City: PORTSMOUTH/NEWINGTON PEASE AIR FORCE BASE Site Information: Site Name: Address: PEASE AIR FORCE BASE PORTSMOUTH/NEWINGTON, NH EPA ID: EPA Region: NH7570024847 01 Site Alias Name(s): US AIR FORCE PEASE AFB 13 IDENTIFIED WASTE AREAS Record of Decision (ROD): ROD Date: Operable Unit: ROD ID: 09/27/1993 01 EPA/ROD/R01-93/083 Media: Soil, Sediment, Debris, GW Contaminant: VOCs, Other Organics, Metals Abstract: The 23-acre Pease Air Force Base (Operable Unit 1) site is part of the 4,300-acre inactive Air Force base located in Newington and Portsmouth, Rockingham County, New Hampshire. Land use in the area is predominantly commercial and residential, with wetlands and woodlands located onsite. Current land use at the site is institutional, agricultural, abandoned land, and unoccupied residential. There are three wetlands areas on and adjacent to the site, and many of the 3,700 dwellings located within a 1mile radius of Pease Air Force Base (AFB) have wells and/or springs located on their associated properties. While the Town of Newington has a largenumber of private wells, the vast majority of Portsmouth residences are serviced by municipal water only. From 1951 to 1991, the site was used as a military installation by the U.S. Navy and Air Force. During its history, Pease AFB was the home of the 100th and the 509th Bombardment Wings, whose mission was to maintain a combat-ready force capable of long-range bombardment operations. The New Hampshire Air National Guard currently is stationed at the air field area and uses some of the facilities. Over time, various quantities of fuels, oils, solvents, lubricants, and protective coatings were used at the base, and releases of contaminants into the environment occurred. Zone 1 encompasses six areas of concern: LF-2, LF-3, LF-4, LF-5 (the source area OU for the Landfill-5 area), the Bulk Fuel Storage Area, and the Paint Can Disposal Area. The 23-acre LF-5 area was used from 1964 to 1979 as the base's primary landfill for domestic and industrial refuse. Types of waste disposed of in LF-5 include waste oil and solvents, paints, paint strippers and thinners, pesticide containers, and empty cans. A small drum staging area located at the southern entrance to the landfill was used for the temporary storage of drums encountered onsite, miscellaneous soil, and metals. In addition, the landfill received an estimated 20,000 gallons of sludge from the base industrial wastewater treatment plant, which may have contained TCE residues, grass clippings, wood chips, miscellaneous soil, and concrete rubble. There are several surface water pathways that channel surface runoff away from the LF-5 area toward the Piscataqua River. Surface drainage from LF-2 and LF-4, other inactive landfills in the vicinity, as well as from a portion of LF-5, flows into ditches located on both sides of the Railway Ditch and leads to a swampy area. A portion of LF -5's surface runoff enters directly into Flagstone Brook and flows north into the Piscataqua River. Site contamination has severely affected surface waters and sediment due to overland flow and ground water discharge. In 1983, an onsite investigation was conducted in three stages at the Pease site as part of the Department of Defense's Installation Restoration Program (IRP). The first stage revealed elevated contamination levels in soil anddebris in the LF-5 area and, in 1987, the second stage identified 5- and 55- gallon drums in the LF-5 area as a potential threat to human health and the environment. In 1991, as part of the third stage of the investigation, 54 85-gallon overpacks containing drums and waste material and more than 2,000 empty, crushed drums were removed and disposed of offsite. Based on the Phase II IRP investigation, a total of 20 sites at Pease AFB will be investigated further. Studies conducted during the RI determined that previous improper landfilling operations have caused contamination of native soil and that burned refuse now is in contact with ground water and fractured bedrock. In 1993, EPA determined that two other landfills in Zone 1 (LF-2 and LF-4) should be considered concurrently with LF-5. This ROD addresses onsite contaminated soil, sediment, debris, and ground water in the LF-2, LF-4, and LF-5 areas, as OU1. Future RODs will address ground water contamination in Zone 1 and sediment contamination in Flagstone Brook, onsite drainage ditches, and associated wetlands, if necessary. The primary contaminants of concern affecting the soil, sediment, debris, and ground water are VOCs, including benzene; other organics, including PAHs; and metals, including arsenic, chromium, and lead. SELECTED REMEDIAL ACTION: The selected remedial action for this site includes excavating, dewatering, and consolidating 221,500 yd[3] of landfill soil and debris that would still be in contact with ground water after capping; consolidating any soil and waste materials from LF-2 and LF-4 on LF-5; backfilling the excavated area with clean fill to a level at least 2 feet above the natural ground water table after capping, and placing excavated waste above the cleanfill; excavating and consolidating 3,200 yd[3] of sediment from the Railway Ditch that contain contaminants exceeding site-specific cleanup goals; utilizing erosion control measures during sediment excavation and transporting excavated sediment to a central staging area for thickening; dewatering and bulking excavated material, as required, and disposing of excavated sediment onsite on LF-5; capping LF-5 after consolidation of all waste and soil with a 1,200,000 ft[2] RCRA-approved composite barrier cap; installing a passive gas collection system to capture and vent landfill gases; treating ground water extracted during dewatering process onsite using multi-media filtration, ion exchange, and activated carbon adsorption; discharging the treated ground water to the onsite wastewater treatment facility; disposing of all treatment residuals including concentrated salt solution, iron sludge, and spent activated carbon offsite; restoring any affected wetlands, as needed; monitoring soil gas, ground water, and air; and implementing institutional controls, including deed restrictions, and site access restrictions such as fencing. The estimated present worth cost for this remedial action is $23,992,000, which includes an estimated present worth O&M cost of $6,629,721 for 30 years. PERFORMANCE STANDARDS OR GOALS: Chemical-specific ground water cleanup goals are based on health and ecological risk-based concentrations for soil and solid waste in the LF-5 area and health-based concentrations for Railway Ditch sediment, and include arsenic 50 ug/l; benzene 5 ug/l; lead 15 ug/l; and TCE 5 ug/l for ground water; arsenic 0.508 mg/kg and lead 0.065 mg/kg for soil and debris; and arsenic 33 mg/kg; lead 35 mg/kg; and total PAHs 4 mg/kg for sediment. Deed restrictions will be implemented to restrict future construction activities that could violate the integrity of the cap. Remedy: This action addresses the principal threat posed by Landfill 5 by preventing endangerment of public health, welfare, or the environment by implementation of this ROD which calls for consolidation and containment of landfill wastes. The selected remedy includes excavation and consolidation, above the groundwater table, of saturated Landfill 5 debris and construction of a cap over Landfill 5. It is also proposed that all soil and debris from Landfills 2 and 4 would be excavated and transported to Landfill 5 for consolidation and used as subgrade fill material prior to capping of Landfill 5. A final decision under CERCLA for Landfills 2 and 4 will be required prior to implementation of the proposed consolidation plan. The selected remedy also includes extraction of groundwater to facilitate excavation of saturated landfill debris, treatment of the groundwater in an on-site mobile treatment system and discharge of treated groundwater to the base wastewater treatment facility. The selected remedy is expected to prevent the potential for direct contact between contaminated landfill soils/debris and human and ecological receptors, and to minimize contaminant leaching to sediments and surface waters of Flagstone Brook and Railway Ditch and to groundwater. The treatment processes used to treat groundwater extracted during construction dewatering will ultimately be selected by the remedial contractor providing the mobile treatment system. Technologies considered in the Feasibility Study include carbon adsorption, ion exchange and multi-media filtration. The preferred discharge method for the treated water is to the base wastewater treatment facility. Coordination with the City of Portsmouth as the current operator, would be required prior to discharge. Treated water will meet the pretreatment criteria established by the City of Portsmouth. Ultimate discharge will be to the Great Bay via a National Pollutant Discharge Elimination System (NPDES) permit. As part of Landfill 5 closure the Air Force will submit a monitoring program for approval by the NHDES and the USEPA. The purpose of the monitoring program is to verify the effectiveness of the containment system. Text: Full-text ROD document follows on next page.

This decision document was developed in accordance with the Comprehensive Environmental Response, Compensation, and Liability Act as amended by the Superfund Amendments and Reauthorization Act of 1986, and, to the extent practicable, the National Contingency Plan. Through this document the Air Force plans to remedy the threat to human health, welfare or the environment posed by contaminated soil, debris, and sediment associated with Landfill 5. Contaminated groundwater, surface water, and additional sediment associated with Landfill 5 will be addressed in the Zone 1 FS. This decision is based on the Administrative Record for the site. The Administrative Record for the site is located at the Information Repository in Building 43 at Pease International Tradeport (formerly Pease AFB, New Hampshire). The Administrative Record Index as applies to Landfill 5 may be found in Appendix D. The State of New Hampshire Department of Environmental Services (NHDES) and the U.S. Environmental Protection Agency (USEPA) concur with the selected remedy. ASSESSMENT OF THE SITE Actual or threatened releases of hazardous substances from Landfill 5, if not addressed by implementing the response action selected in this Record of Decision (ROD), may present an imminent and substantial endangerment to public health, welfare, or the environment. DESCRIPTION OF THE SELECTED REMEDY This action addresses the principal threat posed by Landfill 5 by preventing endangerment of public health,, welfare, or the environment by implementation of this ROD which calls for consolidation and containment of landfill wastes. The selected remedy includes excavation and consolidation, above the groundwater table, of saturated Landfill 5 debris and construction of a cap over Landfill 5. It is also proposed that all soil and debris from Landfills 2 and 4 would be excavated and transported to Landfill 5 for consolidation and used as subgrade fill material prior to capping of Landfill 5. A final decision under CERCLA for Landfills 2 and 4 will be required prior to implementation of the proposed consolidation plan. The selected remedy also includes extraction of groundwater to facilitate excavation of saturated landfill debris, treatment of the groundwater in an on-site mobile treatment system and discharge of treated groundwater to the base wastewater treatment facility. The selected remedy is expected to prevent the potential for direct contact between contaminated landfill soils/debris and human and ecological receptors, and to minimize contaminant leaching to sediments and surface waters of Flagstone Brook and Railway Ditch and to groundwater. The treatment processes used to treat groundwater extracted during construction dewatering will ultimately be selected by the remedial contractor providing the mobile treatment system. Technologies considered in the Feasibility Study include carbon adsorption, ion exchange and multi-media filtration. The preferred discharge method for the treated water is to the base wastewater treatment facility. Coordination with the City of Portsmouth as the current operator, would be required prior to discharge. Treated water will meet the pretreatment criteria established by the City of Portsmouth. Ultimate discharge will be to the Great Bay via a National Pollutant Discharge Elimination System (NPDES) permit. As part of Landfill 5 closure the Air Force will submit a monitoring program for approval by the NHDES and the USEPA. The purpose of the monitoring program is to verify the effectiveness of the containment system. STATUTORY DETERMINATIONS The selected source control remedy is protective of human health and the environment, complies with federal and state requirements, that are legally applicable or relevant and appropriate to the remedial action, is cost effective and uses permanent solutions. Treatment is not the principal element of the source control alternative because treatment of landfill debris is not practical or cost-effective given the size and heterogeneity of the landfill contents. The selected source control remedy may however involve treatment of groundwater extracted during construction dewatering, which should remove much of the contaminants currently present in groundwater. Because this remedy will result in hazardous substances remaining on site, a review will be conducted by the USAF, the USEPA, and the NHDES within five years after landfill closure to ensure that the remedy is providing adequate protection of human health and the environment. This review will be conducted at least every five years as long as hazardous substances remain on site above health-based cleanup levels. The foregoing represents the selection of a remedial action by the United States Air Force and the U.S. Environmental Protection Agency, Region I, with concurrence of the New Hampshire Department of Environmental Services. Concur and recommended for immediate implementation: I. SITE NAME, LOCATION, AND DESCRIPTION Pease AFB is a National Priorities List site consisting of numerous areas of contamination. This ROD addresses source area contamination at Landfill-5 (LF-5). LF-5 encompasses approximately 23 acres in the northern section of Pease AFB. Records indicate that LF-5 was used continuously from 1964 to 1975 as the primary base landfill, although some disposal occurred as late as 1979. Domestic and industrial refuse reportedly disposed of in the landfill includes waste oils and solvents, paints, paint strippers and thinners, pesticide containers and empty cans and drums. In addition, the landfill received sludge from the base industrial wastewater treatment plant. LF-5 has been investigated under the Air Force Installation Restoration Program (IRP). Results of the investigation indicate that sediments, surface water, soil and groundwater have been impacted by activities at LF-5. The 4,365-acre Pease Air Force Base (AFB) is located in the towns of Portsmouth and Newington, Rockingham County, New Hampshire (approximately 3 miles northwest of the City of Portsmouth). As shown in Figure 1, Pease AFB is located on a peninsula bounded on the west and southwest by Great Bay; on the northwest by Little Bay; and on the north and northeast by the Piscataqua River. The base is situated in the approximate center of the peninsula. At the beginning of World War II, an airport at the current Pease AFB location was used by the U.S. Navy. The Air Force assumed control of the site in 1951, and construction of the present facility was completed in 1956. During its history, Pease AFB has been the home of the 100th Bombardment Wing and the 509th Bombardment Wing whose mission was to maintain a combat-ready force capable of long-range bombardment operations. Over time, various quantities of fuels, oils, solvents, lubricants, and protective coatings were used at the base, and releases of contaminants into the environment occurred. The New Hampshire Air National Guard (NHANG) relocated the 157th Military Airlift Group (MAG) from Grenier Field at Manchester, NH, to Pease AFB in 1966. The mission of the group was changed in 1975, when it was designated as the 157th Air Refueling Group. In December 1988, Pease AFB was selected as one of 86 military installations to be closed by the Secretary of Defense's Commission on Base Realignment and Closure. The base was closed as an active military reservation on 31 March 1991. The New Hampshire Air National Guard remains at the airfield and will use some of the existing facilities. The remainder of the reservation will be divided between the State of New Hampshire's Pease Development Authority (PDA), the Department of the Interior, and the USAF. Land use in the vicinity of LF-5 varies. LF-5 is bordered by Merrimac Drive to the north, an abandoned railroad bed to the east; Flagstone Brook to the west; and a Bulk Fuel Storage Area (BFSA) to the southeast (see Figure 2). Zone features near LF-5 include Landfill-2 (LF-2) to the northeast; Landfill -3 (LF-3) to the east; the BFSA to the southeast; a Paint Can Disposal Area (PCDA) to the south; the Air National Guard's (NHANG) North Ramp to the west; and Landfill-4 (LF-4) to the northwest (see Figure 1). LF-2, LF-3, LF-4, LF-5, and the PCDA are inactive disposal areas located within restricted access areas. The BFSA is still used by the NHANG for bulk fuel storage. The NHANG uses the north ramp for large aircraft maintenance and as a temporary staging area. Undeveloped land is located along the western boundary of LF-5. A portion of the site located at the southern entrance of LF-5 was used as a temporary staging area for drums that were removed from the eastern area of LF-5 in the fall of 1989. This area continues to be used to temporarily store drummed solids and liquids generated during investigation activities conducted as part of the basewide Installation Restoration Program (IRP). Stored drummed solids and liquids are eventually disposed of off-base. Off-base, a commercial and residential area is located along Spaulding Turnpike, approximately 1,000 feet northeast of the Pease AFB eastern boundary and approximately 1,500 feet north of LF-5. An abandoned outdoor theater and a water supply booster station are located approximately 150 feet north of the Pease AFB boundary. A small shop and a shopping mall are located on the eastern side of Spaulding Turnpike. There are approximately 3,700 dwellings within a 1-mile radius of Pease AFB. Based on water usage surveys conducted in 1988 and 1992 and on available U.S. Geological Survey (USGS) and New Hampshire Department of Environmental Services (NHDES) information, it was determined that a number of these dwellings have wells and or springs located on their associated properties. The Town of Newington in particular has a large number of private wells. The vast majority of Portsmouth residences surveyed are serviced by town water only. A complete compilation of area springs and wells for Pease AFB, based on information available to date can be found in the Pease AFB Off-Base Well Inventory Letter Report (F-518). Information is presented in tabular form in Tables 1 through 7 of the Letter Report. Well location maps are provided as attachments to the report. Pease AFB is located on a peninsula within the Piscataqua River drainage basin (see Figure 1). Drainage is radially away from the peninsula, into Great Bay toward the west, Little Bay to the northwest and north, and the Piscataqua River to the east. Little Bay flows into the Piscataqua River at the northern end of the peninsula. Great Bay, Little Bay, and the Piscataqua River are all tidally influenced. Consequently, these bodies of water are subject to semidiurnal water-level variations. There are several surface water pathways that channel surface runoff away from the LF-5 area toward the Piscataqua River (see Figure 2). Surface drainage from LF-2, and portions of LF-3 and LF-5, flows into ditches located on both sides of the railway spur (collectively known as the Railway Ditch), which subsequently flows north and enters a swampy area east of the railroad tracks. The Railway Ditch eventually joins with Flagstone Brook, approximately 3,000 feet north of LF-5. A portion of LF-5's surface runoff flows directly into Flagstone Brook, which flows north through a series of weirs and empties into the Piscataqua River near the General Sullivan Bridge. The total drainage area of the stormwater collection system within the headwaters of Flagstone Brook is approximately 78 acres, which includes a number of industrial areas of the base. Below the confluence of the eastern and western branches, Flagstone Brook flows north along the western edge of LF-5. Surface runoff seeps from LF-5 discharge directly into Flagstone Brook. In addition to the Railway Ditch and Flagstone Brook, several wetland areas exist in the LF-5 vicinity. On and immediately adjacent to the landfill are three wetlands: Wetlands XV, XVI, and XVII (see Figure 3). Wetlands XVI drains to Flagstone Brook and Wetlands XV and XVII drain to the Railway Ditch. East of the landfill, between the railroad and Merrimac Drive, are Wetlands I, II, III, IV, V, and VI. Wetlands I, III, IV, and V drain toward Merrimac Drive, and Wetlands II and VI drain to the Railway Ditch. North of the landfill, there are several wetlands associated with the Railway Ditch and Flagstone Brook. Wetlands VII and VIII are associated with the Railway Ditch until it reaches Wetlands IX and joins Flagstone Brook through a culvert under the railroad. Wetlands X is located north of LF-5 and west of Flagstone Brook and has no identified surface water connection to Flagstone Brook. However, subsurface flow may exist under the roadbed. West of the landfill, Wetlands XIII is immediately adjacent to Flagstone Brook and a portion of it flows into Flagstone Brook near its conjunction with Merrimac Drive. It is not known if LF-5 is within a 100-year flood plain, since flood plain location maps were not available for Pease AFB. A more complete description of the site can be found in the Stage 3C Landfill-5 Remedial Investigation (RI) Report (F-500). II. A. SITE HISTORY AND ENFORCEMENT ACTIVITIES Site Use and Response History Records indicate that LF-5 was used continuously from 1964 to 1975 as the primary base landfill, although some disposal occurred as late as 1979. Domestic and industrial refuse reportedly disposed of in the landfill includes waste oils and solvents, paints, paint strippers and thinners, pesticide containers, and empty cans and drums. In addition, the landfill received an estimated 20,000 gallons of sludge from the base industrial wastewater treatment plant. Sludge from the base wastewater treatment facility, which may have contained trichloroethylene (TCE) residues, grass clippings, wood chips, miscellaneous soils, and concrete rubble, was temporarily stored at the landfill pending ultimate disposal. As previously discussed, a small drum staging area used for temporary storage of drums encountered on-base, miscellaneous soils, and metals is located at the southern landfill entrance. Based on aerial photographs, this area may have been a drum storage area as early as 1960. One method of landfilling used between 1964 and 1975 was trenching. Based on review of aerial photographs and other information, trenches were constructed 15 to 20 feet wide, 150 to 300 feet long, and 6 to 8 feet deep (or to bedrock). The trenches were then filled with refuse and covered with local fill. Today, the settled trenches appear to cover about one-third of the 23-acre landfill. The trenches are located in the north-central, central, and southwestern portions of the landfill. Surface filling or backfilling was also a major landfilling technique used at LF-5. The fill between the trench areas was probably emplaced using these methods. In 1983, an IRP Phase I Problem Identification/Records Search was conducted at Pease AFB. The study identified LF-5 as a potential source for the release of contaminants into the environment. In response to this finding, a pre-survey was conducted to obtain sufficient information for use in the planning of a more detailed study. The pre-survey was completed in 1984. Based on the pre-survey, Remedial Investigations (RIs) were conducted in accordance with the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), as amended by the Superfund Amendments and Reauthorization Act (SARA) of 1986, at LF-5 and at 18 other IRP sites at Pease AFB. The investigations were conducted in three stages between 1984 and 1991. During Stage 2 of the investigation (October 1987 through May 1989) 5- and 55-gallon drums were identified in LF-5. Because these drums were determined to present a potential threat to human health and the environment, fast-track remedial action was initiated. Drum removal was completed during Stage 3 RI field activities. The RI field work was completed in October 1991. During drum removal, 54 85-gallon overpacks containing drums and waste material and over 2,000 empty, crushed drums were removed and disposed of at a licensed off-base disposal facility. To date, LF-5 RI activities have included geophysical surveys, sampling of surface and subsurface soils, test pit investigations, sampling of groundwater beneath and surrounding LF-5, sampling of sediments and surface water in Flagstone Brook and the Railway Ditch, a wetlands determination in the area of LF-5, and measurement of groundwater levels and hydraulic gradients at LF-5. Table 1 provides a summary of RI activities performed to date. A more detailed description of the LF-5 site history can be found in the RI in Subsection 2.1. B. Enforcement History The enforcement history at LF-5 is summarized as follows: • In 1976, the Department of Defense (DOD) devised a comprehensive Installation Restoration Program (IRP) to assess and control environmental contamination that may have resulted from past operations and disposal practices at DOD facilities. • In 1983, an IRP Phase I Problem Identification/Records Search was conducted at Pease AFB. result, a total of 18 IRP sites were identified and 16 were recommended for follow-on investigations (Phase II). • In 1984, Phase II (Problem Confirmation and Quantification) was initiated via conducting a presurvey to obtain sufficient information to plan a more detailed study. Based on the presurvey results, LF-5 and 19 other IRP sites (three areas were dropped and four areas were added as IRP sites) were recommended for further study and were entered into the RI/FS process (F-447). • In October 1987, the Air Force initiated a second part of the Phase II study (Stage 2). At this point, the IRP approach was adjusted to be consistent with the U.S. Environmental Protection Agency's (EPA) Remedial Investigation/Feasibility Study (RI/FS) terminology and philosophy. Stage As a 2 field activities were concluded in May 1989. • Following groundwater analyses in Phase II (Stage 2), five sites were identified for initiation of interim remedial measures (IRMs). LF-5 was among these sites, due to the presence of buried drums in the landfill and due to high contaminant levels in LF-5 soils and groundwater (F-455). • On 14 July 1989, Pease AFB was proposed for addition to the National Priorities List (NPL). effective date of addition was February 1990. • In 1990, a Technical Review Committee (TRC) was established to facilitate communication and coordination among various agencies and the public concerning Pease AFB IRP activities. The TRC assists in keeping the local community apprised of investigative/remedial actions and findings at Pease AFB. The TRC is comprised of individuals representing the Air Force; NHDES; EPA; PDA; the Towns of Newington, Greenland, and Portsmouth; and a community representative. TRC meetings are held monthly. • On 24 April 1991, the U.S. Air Force, EPA, and NHDES signed a Federal Facilities Agreement (FFA) establishing the protocol and timetable for conducting the RI/FS and Remedial Design/Remedial Action (RD/RA) processes at Pease AFB. • In October 1991 (Stage 3), a drum removal IRM was conducted at LF-5. During field activities 54 85-gallon overpacks containing drums, waste materials, and over 2,000 empty, crushed drums were removed and disposed of at an off-base, licensed facility (F-463). The As part of the timetable established in the FFA, the U.S. Air Force, in an effort to streamline activities, designed a basewide strategy plan for conducting an RI/FS investigation. This strategy plan grouped the numerous sites into seven zones. The zones were delineated based on hydrogeological similarities, analytical results, geographical location, surface features, and types of source areas contained within the zones. RI/FS reports have been or will be prepared for each zone. As noted for Stage II, prior to inclusion of Pease AFB on the NPL, five sites, including LF-5, were on an accelerated RI/FS approach because of the potential threat they posed to human health and the environment. The U.S. Air Force, EPA, and NHDES agreed that the source area RI/FS reports, as well as the remedial actions at these sites, would continue on an accelerated track toward source area cleanup, independent of the zones in which they were contained. • In April 1992, the U.S. Air Force submitted a Draft Final RI Report for LF-5 (F-500). • In August 1992, the U.S. Air Force submitted a Draft Final FS for LF-5 (F-494). III. COMMUNITY PARTICIPATION Throughout the site's history, the community has been actively involved. EPA, NHDES, and the U.S. Air Force have kept the community and other interested parties apprised of site activities through informational meetings, fact sheets, press releases, public meetings, and TRC meetings. During January 1991, the U.S. Air Force released a community relations plan, which outlined a program to address community concerns and keep citizens informed about and involved in remedial activities. This plan was updated and released in the summer of 1993. Numerous fact sheets have been released by the U.S. Air Force throughout the IRP program at Pease AFB. These fact sheets are intended to keep the public and other concerned parties apprised of developments and milestones in the Pease IRP. The fact sheets released to date that concern LF-5 are summarized as follows: Fact Sheet Release Date Pease AFB Installation Restoration Program Update October 1991 Pease AFB Installation Restoration Program Update December 1992 Proposed Plan for Landfill-5 Source Area January 1993 Revised Proposed Plan for Landfill-5 Source Area July 1993 In addition to the fact sheets, a number of public meetings have been held concerning the remediation of LF-5. On 14 November 1991 an IRP update public meeting was held and on 12 January 1993 and IRP public workshop and meeting was conducted to provide the public with information on the status of the IRP at Pease AFB. On 27 January 1993 the U.S. Air Force conducted a public hearing and information session for the LF-5 Proposed Plan, during which oral comments on the Proposed Plan were received. A transcript of oral comments received during this meeting and U.S. Air Force response to comments are included in the attached Responsiveness Summary (Appendix C). In addition, a public comment period for the Proposed Plan was conducted between 14 January and 13 February 1993. Responses to written comments received during this period are also included in Appendix C. TRC meetings have been held on a monthly basis since 1990 (see Subsection II.B). Through these meetings, lines of communication among the public and the various lead agencies have been kept open. On 5 August 1993, the U.S. Air Force conducted a public hearing and information session for the Revised Proposed Plan for LF-5 during which comments on the Proposed Plan were received. A transcript of comments received during this meeting and the U.S. Air Force response to comments are included in the attached Responsiveness Summary (Appendix C). In addition, a public comment period for both the Revised Proposed Plan for Landfill-5 and the Proposed Plan for Landfills-2 and -4 was held from 20 July to 19 August 1993. Responses to written comments received during that period are also included in Appendix C. A complete information repository, containing documents relating to the Pease AFB IRP, is maintained at Pease AFB in Building 43. An administrative record pertaining to the Pease AFB IRP is located in Building 43 of Pease AFB. An index of the administrative record is maintained in the EPA Region I Headquarters. IV. SCOPE AND ROLE OF OPERABLE UNIT OR RESPONSE ACTION Zone 1 encompasses six areas of concern, including the source area operable unit for LF-5. Other areas of concern include LF-2, LF-3, and LF-4, the BFSA, and the PCDA. The remedy presented in this Record of Decision (ROD) provides for source control at LF-5. Remediation at a Superfund site typically involves activities to remove or isolate contaminant source materials in conjunction with activities that mitigate migration of contamination through groundwater, surface water, and/or air pathways. This ROD addresses only source control measures. Management of contaminant migration will be addressed in a separate ROD for Zone 1, which is scheduled for completion in September 1994. Source materials at LF-5 have been identified as landfill soil and solid wastes, landfill surficial soils, and sediment in the Railway Ditch and associated wetlands. Although sediment in Flagstone Brook may represent an additional source, contaminants present in this medium may be directly related to runoff from other sources and, therefore, are addressed in the Zone 1 Draft FS, which was completed in August 1993, rather than in the LF-5 source control FS. Groundwater and surface water are not considered source materials, however, remedial action objectives (RAOs) and cleanup goals have been established for these media, as well as for the source materials, since they will be affected by source control activities. Subsequent to the completion and public review of the original Proposed Plan for LF-5, it was proposed that two additional source areas, LF-2 and LF-4, be excavated (in their entirety) and consolidated on LF-5. The volume increase of materials consolidated on LF-5 would total approximately 76,320 cubic yards (yd[3]). The two landfills, which are adjacent to (in the case of LF-2) or within 200 feet (in the case of LF-4) of LF-5, cover a total area of approximately 12 acres. The materials in LF-2 and LF-4 are mainly soil and debris as with LF -5. In keeping with the public's desire to consolidate landfill materials wherever possible to provide for more available land whose future use is not restricted, it was determined that consolidation of LF-2 and LF-4 onto LF-5 would be the best strategy in terms of meeting the public's requests. Because LF-2 and LF-4 are part of the Zone 1 operable unit, consolidation of LF-2 and LF-4 onto LF-5 will be addressed in the Zone 1 Proposed Plan and ROD. A final decision under CERCLA will be required prior to implementation of the LF-2 and LF-4 excavation and consolidation plan. The selected source control remedy for LF-5, as described in the Proposed Plan, was developed by combining components of different source control technologies to aid in obtaining a comprehensive approach for site source area remediation. In summary, the remedy provides for: • Excavation and consolidation of selected sediments on the existing landfill. • Excavation of soil and debris in LF-2 and LF-4 and consolidation on LF-5 (not included in the original LF-5 Proposed Plan but added in the revised Proposed Plan). • Excavation of soil and solid wastes predicted to be below the water table after capping and placement of excavated material on the existing landfill. Dewatering of areas requiring excavation, on-site treatment of the extracted groundwater, and discharge to the local publicly-owned treatment works (POTW) may be necessary. • Regrading and capping of the existing landfill. • Conducting long-term environmental monitoring and placement of institutional controls. The remedial action addresses the following primary risks and principal threats to human health and the environment posed by the site: • Risks posed to ecological receptors from direct contact with, or ingestion of, sediment in the Railway Ditch and associated wetlands containing contaminants in excess of concentrations that may present a risk. • Risks posed to humans from direct contact with, or ingestion of, contaminated soils or debris that may present a health risk. • Risks posed to ecological receptors from direct contact with, or ingestion of, soil or debris containing contaminants in excess of concentrations that may present health risks. • Migration of contaminants from soil or debris within the LF-5 source area into the groundwater, which may inhibit attainment of the groundwater RAOs for Zone 1. • Migration of contaminants from soil or debris within the LF-5 source area into surface water, including wetlands, which may inhibit attainment of the surface water ROAs for Zone 1. The selected source control remedy will complete the mitigation of the site risks related to source areas as described in Subsection 1.6 of the LF-5 FS (F-494). V. SUMMARY OF SITE CHARACTERISTICS Subsections 1.3 and 1.4 of the FS contain an overview of the RI. Based on the results of the RI, a working conceptual model was developed that incorporates all known data concerning LF-5 and vicinity, including geological, hydrological, analytical, field measurements, and visual observations. The salient points of the model are summarized as follows: • Several primary, discrete contaminant source areas exist within LF-5. • Landfill operations have caused the excavation of native soils down to bedrock in places; consequently, buried refuse is in direct contact with groundwater and weathered and fractured bedrock. • Contaminated soil is a likely source for some of the contaminants that have been observed in other matrices in the LF-5 area. • An enhanced groundwater recharge area for LF-5 and its vicinity overlaps the central trench area. • Groundwater within LF-5 is contaminated with halogenated volatile organic compounds (VOCs), aromatic VOCs, and semivolatile compounds (SVOCs); metals; and pesticides. The concentrations of a few of these substances exceed federal and state standards. • Aromatic and halogenated VOCs are discharged from groundwater to surface water in the Railway Ditch and Flagstone Brook. • A groundwater plume containing VOCs (halogenated) is migrating from LF-5. • The extent of the halogenated VOC plume east of the Railway Ditch is known; the downgradient limit coincides with wells 5009 and 6003. • Surface water and sediment in Flagstone Brook appear to be affected by other sources in addition to LF-5. • Surface water and sediment in the Railway Ditch appear to be significantly affected by LF-5. The results of the RI as conceptualized are discussed in more detail in the subsections that follow. A. Subsurface Soils and Solid Waste Source characterization at LF-5 included the collection and analysis of subsurface soil and solid waste samples. Subsurface soils refer to material collected at a depth of 2 feet or greater. All subsurface soil samples were collected from the landfill over a period of 4 years. Samples were obtained from approximately 30 test pits and several samples were collected during drum removal operations. Figure 4 depicts the distribution of organics in subsurface soils in and adjacent to LF-5. Major findings of the analyses of all test pit soil samples are summarized as follows: • The highest total SVOCs were detected within the drum removal area. • The highest total VOCs were detected in soils collected near the central trench area. Total xylenes were the largest component [33 milligrams/kilogram (mg/kg)] of the total aromatic VOCs. 1,4-Dichlorobenzene (DCB) was detected in soil from the southwestern corner of the central trench area at a concentration of 0.140 mg/kg. • Low concentrations of total aromatics were detected in test pit soils collected from the northern trench area. • TCE was detected in soils from test pit 9014 at a concentration of 0.005 mg/kg. • Arsenic was detected above the background concentrations in the sample from test pit 9018. The copper background concentration was exceeded in samples from test pit 9013. Zinc concentrations exceeded the background concentration in samples from test pits 983, 9013, 9015, 9016, and 9018. • Cadmium concentrations exceeded the background concentrations in samples from test pits 9013, 9016, and 9021. The mercury background concentration was exceeded in samples from test pits 9016 and 9017. Lead concentrations exceeded the background concentration in samples from test pits 982, 983, 984, and 9016. The nickel background concentration was exceeded in the sample from test pit 9015. Soil samples from test pits 9016 and 9020 were also subjected to the Toxicity Characteristic Leaching Procedure (TCLP). Leachate was analyzed for VOCs, SVOCs, metals, pesticides, and herbicides. Laboratory data indicate that no TCLP regulatory limits were exceeded. Contaminants in subsurface soils at LF-5 are of concern since they are, in some landfill areas, in contact with groundwater and have the potential to migrate from the site via this medium. B. Surface Soils A total of 32 landfill surface soil samples (336 through 367) were collected from a depth of 0 to 2 feet to characterize the landfill cover soil. Surficial (0 to 2 feet) test pit samples were also used to describe the landfill cover soils. Figure 5 depicts the distribution of organics in surface soils in and adjacent to LF-5. The results of the laboratory analyses may be summarized as follows: • Aromatic and halogenated VOCs were detected at low concentrations in soils collected from all areas of the landfill. The highest concentrations were detected in soils from test pit 983 and soil sample 357. • SVOCs were detected in all soil samples. From areas outside the drum removal area, total concentrations ranged from 0.06 mg/kg(9013) to 1,684 mg/kg (360). Most of the highest total SVOCs were detected in soil samples collected from the drum removal area (345,354, and 355) and test pits from the drum removal area (982, 983, and 984). • Polynuclear aromatic hydrocarbons (PAHs) (e.g., chrysene) were most often detected in soil from the drum removal area. • The highest concentrations of total petroleum hydrocarbons (TPHs) were detected in the samples from location 364 (2,500 mg/kg) from the northern trench area and location 345 (2,200 mg/kg) from the drum removal area. • Pesticides were detected in most of the surface soil samples. Both heptachlor and dieldrin were elevated in the sample from location 354 (drum removal area), and dieldrin was detected in the sample from locations 366 and 984. • Most of the samples that contained metals that exceeded the background concentrations were collected from the drum removal area and the northern trench area. Table 2 includes a summary of locations and concentrations that have metals concentrations that exceed background in surface soils at LF-5. • One surface soil sample (9013) was subjected to TCLP. Leachate from the test was analyzed for VOCs, SVOCs, metals, pesticides, and herbicides. Preliminary laboratory data indicate that TCLP regulatory limits were not exceeded. Contaminants in surface soils at LF-5 are of concern because of the potential for direct human and ecological receptor contact with these soils and the potential for contaminants in surface soils to migrate to surrounding surface water bodies and wetlands. C. Surface Water and Sediments The LF-5 surface drainage system consists of two main drainage channels. The first, Flagstone Brook, has its headwaters at the North Ramp and flows northward forming the western boundary of LF-5. The second, the Railway Ditch, flows northward along the eastern border of LF-5, eventually joining Flagstone Brook, approximately 3,000 feet north of LF-5. Flagstone Brook eventually drains to the Piscataqua River to the east of Pease AFB. Nine surface water/sediment stations were sampled to characterize Flagstone Brook, while 15 stations were sampled to determine the impact of LF-5 on the Railway Ditch. Sampling results and data interpretation are discussed in Subsection 4.5 of the Zone 1 Draft Final RI (F-500). The sampling history of all LF-5 surface waters and sediment stations is summarized in Appendix B of that document. Figures 6 and 7 present the distribution of organics in LF-5 surface waters and sediments, respectively. Tetrachloroethene (PCE) is the only VOC confirmed in the surface waters of Flagstone Brook at concentrations greater than 1 microgram per liter (ug/L). This sample was collected at station 821 during the January 1990 sampling round. No SVOCs were detected in the Flagstone Brook surface waters. The pesticide DDT and its metabolite DDE were the only pesticides confirmed in Flagstone Brook surface waters; these two compounds were detected at concentrations of 0.14 ug/L and 0.2 ug/L, respectively, at station 819 during the May 1989 sampling round. Polychlorinated biphenyls (PCBs) were not detected at any location. The highest concentrations of aromatic VOCs and SVOCs in the Flagstone Brook watershed were detected at seeps 8079 and 826, respectively. Total aromatic VOCs were detected at 54 ug/L for station 8079 during the October 1991 sampling round, and the SVOC 4-methylphenol was detected at 3.0 ug/L for station 826 during the September 1989 sampling round. DDT (station 819) was the only organic compound detected in the Flagstone Brook watershed that exceeded ambient water quality criteria (AWQC) (0.001 ug/L). VOCs were not detected in any of the sediment samples taken in Flagstone Brook; however, VOCs were detected in seep sediments. The VOCs detected in sediments were chlorobenzene (0.07 mg/kg) and 1,4-DCB (0.002 mg/kg) at seep 8079. SVOCs have been detected in the sediments of all but two of the stations (stations 821 and 821A) in the Flagstone Brook watershed. Stations 8031 and 8032 had the highest total sediment SVOC concentrations, 3.07 mg/kg and 2.48 mg/kg, respectively. The greatest contributors to the total SVOC concentrations at all stations were PAHs. It is important to note that the highest total SVOC concentration was reported for station 8031, which is upgradient from LF-5. This implies that sources other than LF-5 are contributing SVOCs and possibly other contaminants to surface water and sediments in the Flagstone Brook drainage. Pesticides/PCBs were detected in the sediments at six stations in the Flagstone Brook drainage. The highest total pesticide/PCB concentration was detected at the upgradient station (8031) and was based on a single hit of 1.00 mg/kg for heptachlor epoxide. Other pesticides/PCBs observed in Flagstone Brook drainage sediments, and the number of stations at which they were reported include: 4,4'-DDT (4), 4,4'-DDE (3), gamma-chlordane (1), and Aroclor-1260 (1). Inorganic concentrations in surface waters in the Flagstone Brook drainage were compared with the State of New Hampshire freshwater chronic criteria for the protection of aquatic life, when available. Metals for which criteria are hardness- or pH-dependent have been adjusted assuming hardness of 20 mg/L and pH of 6.5. The state AWQC for seven inorganics were exceeded at one or more stations in the Flagstone Brook drainage. Zinc concentrations at stations 819, 819A, 826, 8031, and 8079 exceeded the state AWQC (0.027 mg/L). The state AWQC for iron (1.0 mg/L) was exceeded at stations 819, 826, 8031, and 8079; and the state AWQC for lead (0.000041 mg/L) was exceeded at three stations (826, 8031, and 8079). The four other compounds that exceeded surface water criteria and the number of stations are beryllium (1), copper (2), nickel (1), and thallium (1). Inorganic sediment concentrations in the Flagstone Brook drainage were compared to concentrations at upgradient station 8031. Station 8031 had the highest detected concentrations of barium (445 mg/kg) and chromium (91.9 mg/kg) in sediments when compared to other Flagstone Brook drainage samples. In general, inorganic sediment concentrations did not exceed the upgradient sample by more than an order of magnitude, the exceptions being mercury and beryllium, which were not detected at station 8031. Mercury was identified in a duplicate sample taken at station 8032 (0.15 mg/kg) in June 1991. Beryllium was identified at stations 819A (0.27 mg/kg) and 8079 (0.41 mg/kg) during June and October 1991 sampling, respectively. The only other compound that exceeded the upgradient concentration by more than an order of magnitude was aluminum, which was detected at station 826 (20,800 mg/kg) in a sample collected in September 1989. Aromatic and halogenated VOCs were detected in surface water at nine stations in the Railway Ditch during the 1991 field investigations at LF-5 (see Figure 7). Aromatic VOCs detected included chlorobenzene, benzene, toluene, ethylbenzene, trimethylbenzene, and butylbenzene. Chlorobenzene was the most frequently detected and also showed the highest concentration of 2.0 ug/L at station 8073. Halogenated VOCs were detected at the same stations where aromatic VOCs were present. Halogenated VOC contaminants included PCE, TCE, transand cis-1,2-dichloroethene (DCE), 1,1-DCA, 1,4-DCB, and 1,2-DCB. TCE, cis-1,2-DCE, 1,1-dichloroethane (DCA), and 1,4-DCB were the dominant halogenated VOCs present in Railway Ditch surface water. TCE was detected at the highest concentration (9 ug/L at station 8074). No aromatic or halogenated VOCs were detected in surface water downstream of station 827. The area of aromatic/halogenated VOC surface water contamination extends from staff gage 8061 downstream to station 820/822. No SVOCs were detected in surface water sampled from the Railway Ditch. The pesticide DDT and its metabolite 4,4'-DDD were detected in surface water collected from four Railway Ditch stations (820, 827, 828, and 8074). The highest concentrations of DDT and 4,4'-DDD in surface water were detected at staff gage 820. No herbicides or PCBs were detected in Railway Ditch surface waters. Aromatic VOCs were detected in sediments at nine stations in the Railway Ditch during the 1991 field investigations at LF-5 (see Figure 7). Aromatic VOCs detected included chlorobenzene, 1,2-DCB, methylene chloride, 2butanone, toluene, and acetone; 2-butanone had the highest detected concentration of 0.2 mg/kg at station 8061. Halogenated VOCs were detected in sediment at three stations in the Railway Ditch and included 1,2-DCE, TCE, and 1,1DCA. The aromatic VOC 1,2-DCE was detected in the highest concentration at station 8036 (0.45 mg/kg). Aromatic VOCs were detected in sediments in the upper Railway Ditch from staff gage 8061 downstream to station 8074, while halogenated VOCs were detected at stations 8074, 8036, and 8073. No VOCs were detected in sediments sampled below station 8074. SVOCs were detected in sediments sampled at eight stations in the Railway Ditch. Phenanthrene, fluoranthene, and pyrene were the most common SVOCs out of a total of 15 SVOC compounds detected. The highest SVOC concentration detected in Railway Ditch sediments was a 27-mg/kg concentration of benzoic acid at station 824. SVOCs were detected throughout the Railway Ditch system from station 824 downstream to station 8033. Pesticides were detected in sediments at 10 stations in the Railway Ditch. DDT was the most widely distributed pesticide in the Railway Ditch sediments and was detected at six stations. The DDT metabolites 4,4-DDE and 4,4-DDD were both detected at seven stations in the Railway Ditch. The highest sediment concentration of pesticide (DDT) was detected at station 8036. No herbicides or PCBs were detected in Railway Ditch sediments. Inorganic concentrations detected in surface waters of the Railway Ditch drainage were compared with the State of New Hampshire freshwater chronic criteria for the protection of aquatic life. State AWQC for five inorganics were exceeded at one or more stations in the Railway Ditch drainage. Arsenic concentrations at stations 8036, 8037, and 8073 exceeded the state AWQC (0.048 mg/L). State AWQC for copper (0.003 mg/L) was exceeded at stations 8035 and 8061. A total of 10 stations (820, 823, 827, 8035, 8036, 8037, 8061, 8072, 8073, and 8074) exceeded the state AWQC for iron (1.0 mg/L). Lead concentrations at seven stations (820, 822, 8035, 8036, 8061, 8072, and 8073) exceeded the state AWQC (0.00041 mg/L), and the state AWQC for zinc (0.027 mg/L) was exceeded at stations 8035, 8036, 8037, and 8061. Railway Ditch sediment concentrations of inorganics were compared to the upgradient station on Flagstone Brook (8031). Inorganics concentrations in Railway Ditch sediments that were one order of magnitude greater in concentration than those detected at station 8031 are described as follows. Eight sediment inorganics were one order of magnitude greater in concentration than those detected at station 8031. These included: arsenic at seven stations, iron at one station, lead at two stations, calcium at three stations, cobalt at one station, potassium at one station, manganese at six stations, and silicon at eight stations. Four inorganics (beryllium, selenium, silver, and thallium) detected in Railway Ditch sediments were not detected at station 8031. Potential pathways by which contaminants have entered Flagstone Brook and the Railway Ditch include overland flow (erosion) and groundwater discharge. The PAHs and pesticides observed in sediments are transported via erosion of LF-5 soils. VOCs detected in the Railway Ditch surface waters reflect contaminated groundwater discharge. The relative absence of VOCs in Flagstone Brook surface waters may result from dilution, losses due to volatilization, or a smaller contaminant load migrating westward, as opposed to eastward toward the Railway Ditch. Halogenated VOCs in Railway Ditch waters have been determined to have originated from three separate source locations in the vicinity of LF-5; the central trench area (chlorobenzene, 1,4-DCB, and C-1,2-DCE), the southern trench area (PCE), and an area south of the landfill near the PCDA. Based on sampling results in Flagstone Brook and the Railway Ditch, it is estimated that approximately 3,000 yd[3] of Railway Ditch sediments will require remediation. D. Groundwater During the LF-5 characterization, 38 groundwater sample locations were tested for VOCs with varied frequency. Both aromatic and halogenated VOCs have been detected on- and off-site. However, the off-site aromatic VOCs have been detected in wells 502 and 5008. Well 5008 is downgradient of both LF-5 and the BFSA. All of the groundwater samples collected from monitor wells installed within the established LF-5 boundary have contained VOCs. Outside the landfill boundary, halogenated VOCs were detected in samples collected from five wells located east of the southern section of LF-5 (502, 538, 568, 626, and 6003); and one well located northeast of the landfill (5011). Figure 8 depicts the distribution of the concentrations of total halogenated VOCs, total aromatic VOCs, and total SVOCs for each well. The highest concentrations of total aromatic VOCs (primarily benzene, chlorobenzene, and 1,4-DCB) and SVOCs are typically detected in groundwater collected from wells near the central trenches (567, 603, 604, 605, and 6005). The highest concentrations of halogenated VOCs, primarily TCE and PCE, in groundwater are hydraulically downgradient of the southeastern corner of LF-5, but low concentrations have been detected in samples from one well, located adjacent to the central portion of the southern boundary, during three separate sampling events. Low concentrations of dichlorinated alkenes and alkanes cis-1,2-DCE, 1,1-DCA, and 1,2-DCA are present across the landfill, but the higher concentrations (>5 ug/L) are restricted to the southeastern region of LF-5. The highest detected concentrations of total SVOCs and total aromatic VOCs have been in the central trench area (605 and 606); benzene has repeatedly exceeded the Federal Maximum Contaminant Level (MCL) of 5 ug/L in samples collected from one well (5014) in this area. No other final or proposed MCLs have been exceeded for aromatic VOCs or SVOCs at LF5. The MCLs for TCE (5 ug/L) and vinyl chloride (2 ug/L) have been exceeded in groundwater samples collected from well 502, and the MCL for PCE (5 ug/L) has been exceeded in all samples from wells 502 and 538. Groundwater samples collected from 38 wells in and around LF-5 have been analyzed for pesticides. Low concentrations (below quantitation limits) of either delta-BHC, endosulfan I, or 4,4'-DDD have been detected in groundwater samples collected from three of the wells (605, 606, and 629). The two samples containing endosulfan I were collected from wells located downgradient of the central trench area (605 and 606). The concentrations present are not above any existing federal or state criteria. No herbicides have been detected in groundwater samples collected from the wells in and around LF-5. A total of 96 groundwater samples collected from 38 wells were analyzed for dissolved metals. Table 3 summarizes those wells at which dissolved metal concentrations have exceeded background. Iron and manganese were consistently present at concentrations above established background concentrations near the central trench area (wells 567, 604, 605, 606, 630, 6005, and 6006). In all wells in which dissolved manganese concentrations exceeded the background concentrations, aromatic VOCs were detected. A similar correlation exists with dissolved iron except in wells 508 and 5010, which do not contain VOCs. The majority of the metals concentrations that were present in elevated concentrations were located in wells near the central trenches. Dissolved arsenic was detected above the background concentration (50 ug/L) in seven wells; six of these wells are located near the central trenches (567, 605, 630, 6005, and 6006) and the seventh (501) is located downgradient of the BFSA. Dissolved arsenic was detected at lower concentrations in wells that are hydraulically upgradient of the trench area (502 and 505), and in well 629. Contaminant migration in groundwater beneath and adjacent to LF-5 is discussed in detail in Subsections 5.2 and 5.3 of the Zone 1 Draft Final RI (F-500). The salient points of the discussion are presented in the paragraphs that follow. Six potential groundwater contaminant migration pathways exist at LF-5. and bedrock groundwater pathways to the north, east, and west of LF-5. The six pathways are overburden The bedrock and overburden water-bearing zones within LF-5 are intimately interconnected hydraulically. Excavating and landfilling activities resulted in removal of much of the relatively low-permeability Marine Clay and Silt (MCS) and Glacial Till (GT) units, that, in many other areas, act as an aquitard between the bedrock and overburden aquifers. Consequently, low permeability material, which would otherwise separate groundwater in the overburden from groundwater in the weathered bedrock, is only sporadically present throughout LF-5. The observed contaminant distributions within LF-5 are consistent with the single hydraulic unit model. Groundwater beneath LF-5 is recharged primarily from the south, although a local groundwater mound, which acts as an enhanced recharge zone, has developed in the central trench area. The center of this recharge zone is located north of well 604 (see Figure 8). The location of this recharge zone coincides with an area characterized by elevated concentrations of several aromatic and halogenated VOCs. A north/south-trending groundwater divide transects this recharge zone along an axis through test pits 925, 927, and 928, and bedrock wells 604 and 605. Groundwater (bedrock and overburden) flows radially away from the recharge area and then joins the dominant flow pattern toward Flagstone Brook to the west and the Railway Ditch to the east. Hydraulic gradients across LF-5 indicate that groundwater flows toward both the Railway Ditch and Flagstone Brook, thereby resulting in discharge from the water table to surface water. Although the Railway Ditch was not flowing during the September 1989 surface water sampling event, it appears to be a perennial stream because flow has been noted during all previous and subsequent sampling rounds. Organic contaminants present in surface water samples from staff gages along the Railway Ditch are the same as found in groundwater at LF-5. Although groundwater is also discharging into Flagstone Brook, with the exception of a small amount of PCE in one of four surface water samples collected at staff gage 821, there is a relative absence of contaminants detected in surface water samples. The relative absence of contaminants in Flagstone Brook may result from dilution, because of its relatively high discharge, contaminant losses resulting from aeration and volatilization, and/or it may be a reflection of a relatively smaller contaminant load migrating westward rather than eastward toward the Railway Ditch. E. Wetlands In addition to the Railway Ditch and Flagstone Brook, several wetlands areas exist in the LF-5 vicinity. On and immediately adjacent to the landfill are three wetlands: Wetlands XV, XVI, and XVII (see Figure 3). Wetlands XVI drains to Flagstone Brook and Wetlands XV and XVII drain the Railway Ditch. East of the landfill, between the railroad and Merrimac Drive, are Wetlands I, II, III, IV, V, and VI. Wetlands I, III, IV, and V drain toward Merrimac Drive, and Wetlands II and VI drain to the Railway Ditch. North of the landfill, there are several wetlands associated with the Railway Ditch and Flagstone Brook. Wetlands VII and VIII are associated with the Railway Ditch until it reaches Wetlands IX and joins Flagstone Brook through a culvert under the railroad. Wetlands X is located north of LF-5 and west of Flagstone Brook and has no identified surface water connection to Flagstone Brook. However, subsurface flow may exist under the roadbed. West of the landfill, Wetlands XIII is immediately adjacent to Flagstone Brook and a portion of it flows into Flagstone Brook near its conjunction with Merrimac Drive. More detailed information pertaining to the wetlands in the LF-5 vicinity is presented in the Wetlands Delineation Report in Appendix M of the LF-5 RI (F-500). Based on wetland area surface soil and sediment sampling results that were available during preparation of the FS, it was assumed that sediment in Wetlands VI and XV, located outside the northern boundary of the landfill on either side of the Railway Ditch and south of Merrimac Drive, would require remediation. The estimated volumes of sediment in Wetlands VI and XV that may require remediation are 4,200 yd[3] and 2,400 yd[3], respectively. However, it should be noted that these volumes were conservatively estimated assuming that the entire wetlands will require sediment excavation. While sediment samples from the portions of these wetlands immediately adjacent to the Railway Ditch contained contaminant concentrations exceeding the No Observable Adverse Biological Effects Levels (ER-Ms), published by the National Oceanic and Atmospheric Administration (NOAA) samples were not collected from these wetlands at locations farther away from the Railway Ditch so there are no data to suggest that remediation of the entire wetlands is necessary. Confirmational sampling has been conducted in these wetlands to confirm whether sediment removal is necessary. Remedial volumes resulting from the sampling results will be confirmed prior to implementation of remedial action. Excavation will be avoided, wherever possible, to avoid the adverse long-term effects of wetlands destruction. VI. SUMMARY OF SITE RISKS A Risk Assessment (RA) was performed to estimate the probability and magnitude of potential adverse human health and environmental effects from exposure to contaminants associated with the Site. The public health risk assessment followed a four-step process: 1. Contaminant identification, which identified those hazardous substances which, given the specifics of the site, were of significant concern. 2. Exposure assessment, which identified actual or potential exposure pathways, characterized the potentially exposed populations, and determined the extent of possible exposure. 3. Toxicity assessment, which considered the types and magnitude of adverse health effects associated with exposure to hazardous substances. 4. Risk characterization, which integrated the three earlier steps to summarize the potential and actual risks posed by carcinogenic risks. The results of the baseline human health and ecological risk assessments for Pease AFB are discussed in the subsections that follow. A. Human Health Risk Assessment A total of 75 contaminants of concern, listed in Tables 4 through 12, were selected for evaluation in the human health risk assessment. These contaminants constitute a representative subset of the more than 98 contaminants identified at the site during the RI. The 75 contaminants of concern were selected to represent potential site-related hazards based on toxicity, concentration, frequency of detection, mobility, and persistence in the environment. A summary of the health effects of each of the contaminants of concern can be found in Subsection 6.3.2 and Appendix L.4 of the LF-5 Draft Final RI (F500). The potential human health effects associated with exposure to the contaminants of concern were estimated quantitatively through the development of several hypothetical exposure pathways. These pathways were developed to reflect the potential for exposure to hazardous substances based on the present uses, potential future uses, and location of the site. LF-5 is the largest of the landfills within Zone 1 and is located in the center of the zone. LF-5 currently is not used. The only site being used within Zone 1 is Site 13, the BFSA. It is assumed that future land use within Zone 1 will be restricted to prohibit building construction on the landfills, which includes LF-5. The areas within the zone that are currently or have previously been used for industrial purposes are assumed to have an industrial future use potential. However, areas adjacent to the landfills could be future residential areas, particularly in the northern, eastern, and western portions of the zone. Two surface water bodies, Flagstone Brook and the Railway Ditch, are associated with LF-5. These surface waters may potentially be affected by site contaminants through groundwater discharge and overland flows. Flagstone Brook and the Railway Ditch have no current uses. It is possible, however, that if residential development were to occur in Zone 1 in the future, these surface waters could be used for recreational activities (e.g., wading). Groundwater is not currently used on or immediately downgradient of the site. However, it is possible that in the future the groundwater may be used on the base for industrial purposes (i.e., drinking water, showering, process water) or, if residences were to be built within Zone 1, for domestic use. As such, human health risks due to exposure to groundwater at LF-5 were evaluated in the LF-5 RA included in the LF-5 FS (F-494). While future groundwater use is evaluated in the RA, it is most likely that current off-base public water supply sources would be used. Groundwater is currently used for domestic purposes by local off-base residents. An extensive survey of private wells has given no indication that groundwater contaminants associated with LF-5 have affected private wells. The following is a brief summary of the exposure pathways evaluated. A more thorough description can be found in Subsection 6.3.1 of the RA (Subsection 6.3.1 of the RI). Only source control remedial actions are considered in this ROD. Groundwater remedial actions will be addressed in the Zone 1 FS, scheduled for completion in September 1993. Only one current exposure pathway was evaluated, based on current land use scenarios. The current on-site maintenance worker was assumed to be exposed to contaminants via: 1) incidental soil ingestion, and 2) dermal contact with soil. In each case, the exposure frequency was assumed to be 250 days/year for a duration of 25 years. For ingestion, rates of 7.8 mg/day for the main landfill, 3.1 mg/day for the drum removal area, and 1.6 mg/day for the staged underground storage tank (UST) area were assumed. The drum removal area and staged UST area are locations on the landfill that were identified as hot spots and were consequently evaluated separately in the RA because of the type and concentrations of contaminants in these areas. Future use exposure pathways evaluated were as follows: • Soil - Future maintenance worker (same exposure parameters as current maintenance worker). • Surface water - There are two potentially exposed populations: • • Future Zone 1 resident - This scenario assumes exposure via dermal contact (wading) at a rate of 1 hour/event at a frequency of 75 events per year for Flagstone Brook and 25 events/year for the Railway Ditch, all over a period of 30 years. • Future Zone 1 recreational user - This scenario assumes the same exposure rate, frequency, and duration as the residential scenario. Sediment - Again, both future residential and recreational users are evaluated. In each case, both incidental ingestion and dermal contact were assumed to occur at a rate of 6.25 mg/day (both Flagstone Brook and the Railway Ditch) at frequencies of 75 events/year and 25 events/year for Flagstone Brook and the Railway Ditch, respectively. In each instance, an exposure duration of 30 years was assumed. Summaries of exposure parameters for each pathway evaluated are presented in Table 13 (i.e., exposure frequency, exposure duration, etc.). For each pathway evaluated, an average and a reasonable maximum exposure estimate was generated corresponding to exposure to the average and the maximum concentration detected in that particular medium. Excess lifetime cancer risks were determined for each exposure pathway by multiplying the exposure level with the chemical-specific cancer factor. Cancer potency factors have been developed by EPA from epidemiological or animal studies to reflect a conservative "upper bound" of the risk posed by potentially carcinogenic compounds; i.e., the true risk is unlikely to be greater than the risk predicted. The resulting risk estimates are expressed in scientific notation as a probability (e.g., 1 x 10[-6] for 1/1,000,000) and indicate (using this example), that an average individual is not likely to have greater than a one-in-one-million chance of developing cancer over 70 years as a result of site-related exposure as defined for the compound at the stated concentration. Current EPA practice considers carcinogenic risks to be additive when assessing exposure to a mixture of hazardous substances. The hazard index was also calculated for each pathway as EPA's measure of the potential for noncarcinogenic health effects. A hazard quotient is calculated by dividing the exposure level by the reference dose (RfD) or other suitable benchmark for noncarcinogenic health effects for an individual compound. Reference doses have been developed by EPA to protect sensitive individuals over the course of a lifetime and they reflect a daily exposure level that is likely to be without an appreciable risk of an adverse health effect. RfDs are derived from epidemiological or animal studies and incorporate uncertainty factors to help ensure that adverse health effects will not occur. The hazard quotient is often expressed as a single value (e.g., 0.3) indicating the ratio of the stated exposure as defined to the reference dose value (in this example, the exposure as characterized is approximately one-third of an acceptable exposure level for the given compound). The hazard quotient is only considered additive for compounds that have the same or similar toxic endpoint and the sum is referred to as the hazard index (HI). (For example, the hazard quotient for a compound known to produce liver damage should not be added to a second whose toxic endpoint is kidney damage.) Calculated risks for each individual chemical of concern for each exposure pathway evaluated are presented in Appendix L.7 of the RA. A summary of additive chemical risks for each pathway evaluated is presented in Table 14 of this ROD. The conclusions of the human health risk assessment are summarized in the paragraphs that follow. For the main landfill soils, the cancer risks ranged from 1 x 10[5] to 9 x 10[-4]. The chemicals contributing most of the risk were PAHs (>10[-4]). Aroclor-1242, Aroclor-1248, dieldrin, and arsenic each posed a risk of >10[-6]. The cancer risks posed by contact with hot spot soils was 5 x 10[7] for the staged UST location and ranged from 1 x 10[-3] to 4 x 10[-3] for the drum removal area. PAHs contributed most of the risk for the drum removal area (>10[-4]), followed by dieldrin (>10[-6]). There was no apparent risk of noncancer health effects posed by contact with either main landfill or hot spot soils. The hazard indices for soil were below 1 at all exposure concentrations. Cancer risks based on future groundwater use ranged from 6 x 10[-6] to 3 x 10[-3] based on filtered samples and 1 x 10[-3] to 7 x 10[-3] based on unfiltered (total) samples. Arsenic posed the highest risk (>10[4]). Benzene, bis-(2-ethylhexyl) phthalate (DEHP), 1,4-dichlorobenzene, 1,2dichloroethane, tetrachloroethene, and trichloroethene each posed greater than a 10[-6] risk. The total hazard indices ranged from 30 to 100 based on filtered samples, and from 10 to 40 based on unfiltered samples. Arsenic and thallium had hazard indices that exceeded 10; manganese had a hazard index that exceeded 1. Thallium was detected in unfiltered samples only during one sampling round. The presence of thallium could not be confirmed during subsequent sampling rounds. The cancer risks posed by surface water contact were minimal, ranging from 9 x 10[-10] to 5 x 10[-8] for Flagstone Brook, and from 1 x 10[-9] to 8 x 10[-8] for the Railway Ditch. The hazard indices for both surface waters were below the criterion of 1. The cancer risks posed by contact with sediment in Flagstone Brook were minimal, ranging from 2 x 10[-10] to 3 x 10[-9]. The cancer risks posed by contact with sediment in the Railway Ditch ranged from 2 x 10[-7] to 4 x 10[-6]. Arsenic was the only chemical of concern that posed greater than a 10[-6] risk. The hazard indices for sediment from both Flagstone Brook and the Railway Ditch were below the criterion of 1. B. Ecological Risk Assessment The objectives of the ecological risk assessment were to identify and estimate the potential impacts associated with the chemicals of concern at LF-5, Pease AFB. The assessment focused potential impacts f chemicals of concern found in the soil, surface waters, and sediments to and aquatic flora and fauna that inhabit or are potential inhabitants of the site, including Brook and the Railway Ditch. ecological on the terrestrial Flagstone The species evaluated and their relevant exposure pathways are listed as follows: White-Tailed Deer • • • Incidental ingestion of soil. Ingestion of vegetation (browse). Ingestion of surface water. Shrew • • Incidental ingestion of soil. Ingestion of soil invertebrates (earthworms). Robin • • Ingestion of soil invertebrates (earthworms). Ingestion of surface water. Earthworm • Ingestion/absorption of soil. Aquatic Biota • • Direct contact with surface water. Direct contact with sediments. Terrestrial Plants • Direct contact with soil. Although wildlife present at LF-5 may be exposed to chemicals of concern through the dermal absorption and inhalation routes, there is little scientific information available with which to assess these types of exposures; therefore, these routes of exposure were not evaluated in the RA. t was assumed that exposure to terrestrial wildlife primarily occurs when he animals feed in those areas affected by site contamination. For this assessment, avian and mammalian species with the greatest potential for exposure were selected for evaluation of exposure. Species selected were representative of major foraging guilds and trophic levels that are present LF-5. Although amphibians and reptiles are important components of this ecosystem, sufficient exposure and toxicity data were not available for their evaluation. However, a brief discussion of potential sensitivity of these phylogentic groups to environmental perturbations were included in the uncertainty analysis. An ecological inventory of Pease AFB by the New Hampshire Natural Heritage program did not identify any threatened, endangered, or species of special concern at LF-5. The aquatic life inhabiting Flagstone Brook and the Railway Ditch was described in Section 3 of the RI. The transport and fate of chemicals migrating from the site via surface water runoff, groundwater discharge, or ir transport of dust or vapors may potentially result in the exposure of flora and fauna that inhabit these surface waters. NHDES has adopted many of the AWQC developed by EPA for the protection of 95% of all aquatic life, including fish, aquatic invertebrates, and plants. Comparisons of surface water concentrations with the New Hampshire AWQC for the protection of freshwater aquatic life were used to assess the likelihood of adverse effects to aquatic life. Where AWQC were not available for contaminants of concern, toxicity values were developed from toxicological data in the literature. Where possible, the lowest observed effect level (LOEL) for a species similar to those reported in Flagstone Brook or the Railway Ditch as used. During the FS, in order to assess potential adverse effects to aquatic life rom exposure to sediments, chemicals of concern identified in the sediments f Flagstone Brook and the Railway Ditch were compared with biological effect levels developed by NOAA. The biological effect level used in this assessment was an environmental Effect Range-Low (ER-L) value, which is a concentration that is the lower tenth percentile of a range of sediment concentrations in which biological effects have been observed. Whenever an ER-L was not available for an organic nonpolar chemical, interstitial water concentrations were estimated using the equilibrium partitioning (EP) approach and compared to AWQC or toxicity data. Since completion of the LF-5 Draft Final FS (F-494), it has been determined via review of RA protocols, review of characterization study results for Pease AFB, RI/FS experience at other sites, and discussions with EPA Region I representatives that ER-Ls are unrealistically conservative. Consequently a revised approach to selecting cleanup goals for organic compounds in sediments was instituted at Pease. Rather than using ER-Ls as cleanup goals for organics in sediments, the EP method was used to calculate sediment cleanup goals. Under this method the cleanup goal for a specific organic compound in sediment would be set at that compound concentration in sediment which would not partition to the pore water at a concentration exceeding an established AWQC or other toxicity value. Cleanup goals established for organic contaminants in sediments, as presented in this ROD, may be revised prior to remediation. Cleanup goals for metals in sediments will continue to be ER-Ls. In addition to the comparisons just described, a qualitative evaluation of the benthic community sampling results was presented in Subsection 3.5.3 of the RI and will be summarized in the paragraphs that follow. The distribution and composition of vegetative communities observed at LF-5 were described in Subsection 3.5.1 of the RI. A direct comparison of soil concentrations with available phytotoxicity data was used to qualitatively assess potential adverse effects on vegetation. There is currently no EPA guidance for quantitatively evaluating potential adverse effects to plants growing in contaminated soils. Based on a visual inspection of plants grown at LF-5, no signs of phytotoxic effects (i.e., necrosis, chlorosis, or stunted growth) were observed. New Hampshire and EPA AWQC provide protection for 95% of all aquatic life, including plants. Therefore, potential toxicity to aquatic plants was not evaluated separately, but was taken into account in the comparison of surface water concentrations to the New Hampshire and EPA AWQC. In the case of rooted or emergent aquatic plants, sufficient toxicity data were not available, and therefore, rooted and emergent aquatic plants were not evaluated in the RA. The results of the environmental evaluation indicate chemicals of concern identified in the surface soils, surface waters, and sediments at LF-5 may adversely affect selected target species and aquatic life. In general, the chemicals of concern, by medium, that contributed most to the total hazard indices were as follows: • Soil - Pesticides, benzo(a)pyrene, lead, and zinc. • Surface waters - Aluminum, copper, iron, lead, zinc, and DDT. • Sediments - Arsenic, DDT, DDD, DDE, alpha-chlordane, gamma-chlordane, and lead. Total hazard indices, for target species, based on average and maximum exposure concentrations ranged from 2.76 (deer; hot spot) for average exposure concentrations to 2.86 x 10[4] (masked shrew; hot spot) for maximum exposure concentrations. The hazard indices for LF-5 surface water evaluations, average and maximum concentrations, ranged from 1.47 (Flagstone Brook; acute criteria) to 2,810 (Railway Ditch; chronic criteria), respectively. The hazard indices calculated for the LF-5 sediment evaluation ranged from 77.4 (Flagstone Brook; average concentration) to 12,800 (Railway Ditch maximum concentration). Macrobenthos population analyses were also conducted in Flagstone Brook and the Railway Ditch to provide information in support of the ecological risk assessment for LF-5. Results of the community analyses are discussed in the paragraphs that follow. A total of 1,626 benthic macroinvertebrates representing 47 taxa were collected in 20 samples from in and adjacent to Flagstone Brook stations 8031, 821, 819, and 818. Information on taxa and pollution tolerance values were used to calculate biotic indices for each of the taxa encountered. The one-way analysis of variance (ANOVA) statistical method was performed on the data set to determine whether a significant difference in the total number of organisms and total number of taxa existed between sampling stations. The data show a downstream increase in the total number of taxa while the total number of individuals exhibits no significant increase. Index values were computed for each sample data set from Flagstone Brook. A general trend was observed in the biotic index for Flagstone Brook. At station 8031, the biotic index of 3.1 is indicative of fair water quality. The next station downstream, station 821, had the highest biotic index value (3.8), which is indicative of poor water quality, while biotic index values at stations 819 (3.2) and 818 (2.7) exhibited an improvement in water quality downstream of LF-5. The lowest biotic index value was observed at station 818, which is indicative of good water quality. This corroborates the diversity, evenness, and community similarity data that indicate a downstream improvement in water quality below LF-5. For the Railway Ditch, a total of 218 benthic macroinvertebrates representing 22 taxa were collected from three stations (826, 826, and 828). Stations 827 and 828 were located in the Railway Ditch, and station 826 was located as a control point west of Flagstone Brook. Station 826 was located in a stream similar in size and characteristics to the Railway Ditch stations for use as a control or reference station to compare surface water, sediment, and macrobenthos data. The control station (826) had the most taxa (13) and the largest number of individuals (190) of the three stations sampled. Stations located downstream of LF-5 exhibited a decrease in the total number of taxa in comparison to station 826. Additionally, downstream stations had lower total numbers of individuals in comparison to station 826. A one-way ANOVA was performed on the quantitative data set to determine whether a significant difference in total number of individuals and total number of taxa existed between each sampling station. The results of this statistical analysis indicated that station 826 (control) had significantly more organisms and taxa than either of the two stations located in the Railway Ditch (827 and 828). There were no statistical differences between the two downstream stations with respect to either the number of organisms or the number of taxa. Station 826, the control station, had a biotic index value of 3.4, which is indicative of fair to poor water quality, while stations 827 and 828 had index values indicative of good water quality. The two downstream stations had similar biotic index values, diversities, and species composition and are different from the community at station 826. Actual or threatened releases of hazardous substances from this site, if not addressed by implementing the response action selected in this ROD, may present an imminent and substantial endangerment to public health, welfare, or the environment. However, remediation of LF-5 soils and sediments under the ROD will serve to eliminate LF-5 as a source of contamination, thereby reducing the threat of endangerment. Additionally, Zone 1 groundwater remediation, which is to be addressed in the Zone 1 Draft Final FS (completed in August 1993) will reduce contaminant mobility such that future human health and ecological risk via exposure to groundwater and surface water at and around LF-5 will be reduced to acceptable levels. VII. A. DEVELOPMENT AND SCREENING OF ALTERNATIVES Statutory Requirements/Response Objectives Section 121 of CERCLA establishes several statutory requirements and preferences, including: remedial actions must be protective of human health and the environment; remedial actions, when complete, must comply with all federal and more stringent state environmental standards, requirements, criteria, or limitations, unless a waiver is invoked; the remedial action selected must be cost-effective and utilize permanent solutions and alternative treatment technologies or resource recovery technologies to the maximum extent practicable; and a preference for remedies in which treatment that permanently and significantly reduces the volume, toxicity, or mobility of the hazardous substances is a principal element over remedies not involving such treatment. Response alternatives were developed to be consistent with these mandates. Based on preliminary information relating to types of contaminants, environmental media of concern, and potential exposure pathways, RAOs were developed to aid in the development and screening of alternatives. These RAOs were developed to mitigate existing and future potential threats to public health and the environment via source control. These response objectives for sediment were: • To protect ecological receptors from direct contact with, or ingestion of, sediment containing contaminants in excess of concentrations that may present a health risk (total hazard index greater than 1). • To protect human receptors from direct contact with, or ingestion of, sediment containing contaminants in excess of concentrations that may present a health risk (total cancer risk greater than 10[-4] and a total hazard index greater than 1). Because contaminants in sediment in Flagstone Brook may be originating from upgradient locations, including the North Ramp, remediation of Flagstone Brook sediments will not be addressed in this ROD, but will be addressed in the Zone 1 ROD, as appropriate. The response objectives for landfill soil and solid wastes were the following: To protect humans from direct contact with, or ingestion of, contaminated soils or debris that may present a health risk (total cancer risk greater than 10[-4] or a total hazard index greater than 1). • To protect ecological receptors from direct contact with, or ingestion of, soil or debris containing contaminants in excess of concentrations that may present health risks (total hazard index greater than 1). • To reduce the migration of contaminants from soil or debris into the groundwater, which may inhibit attainment of the groundwater RAOs for Zone 1. • To reduce the migration of contaminants from soil or debris into surface water, which may inhibit attainment of the surface water RAOs for Zone 1. The source control response objective for groundwater and surface water was the following: To reduce the migration of contaminants from sediments and landfill soil and solid wastes within the LF-5 source area, which may inhibit attainment of the groundwater and surface water remedial objectives for Zone 1. • The remedial response objectives for mitigation of contaminant migration will be addressed in the Zone 1 FS and its subsequent ROD. B. Technology and Alternative Development and Screening CERCLA and the National Contingency Plan (NCP) set forth the process by which remedial actions are evaluated and selected. In accordance with these requirements, a range of alternatives was developed for LF-5. With respect to source control, the RI/FS developed a range of alternatives in which treatment that reduces the toxicity, mobility, or volume (TMV) of the hazardous substances is a principal element. This range included an alternative that removes or destroys hazardous substances to the maximum extent feasible, eliminating or minimizing to the degree possible the need for long-term management. This range also included alternatives that treat the principal threats posed by the site but vary in the degree of treatment employed and the quantities and characteristics of the treatment residuals and untreated waste that must be managed; alternatives that involve little or no treatment but provide protection through engineering or institutional controls; and a no action alternative. VIII. DESCRIPTION OF ALTERNATIVES The information presented in the LF-5 Draft Final RI was used to prepare an FS. The FS provides a screening of 13 source control remedial alternatives. Five alternatives passed through the screening process and were retained for detailed evaluation. This section provides a narrative summary of each alternative evaluated. of each alternative can be found in Table 5.3-1 the FS. A detailed tabular assessment A. Source Control Alternatives Analyzed The source control alternatives analyzed for the site include: • Alternative SC-1: CERCLA). P10O No Action/Institutional Controls (considered as a baseline requirement by • Alternative SC-2A: Sediment and Landfill Consolidation, Landfill Capping, and Potential On-site Construction Dewatering, Treatment, and Disposal. • Alternative SC-3A: Sediment Consolidation, Landfill Capping, and On-site Landfill Waste Dewatering, Treatment, and Disposal. • Alternative SC-4D: Sediment and Landfill Consolidation, Hot Spot Thermal Treatment On-site, Landfill Capping, and Potential On-site Construction Dewatering, Treatment, and Disposal. • Alternative SC-5A: Sediment and Landfill Waste On-site RCRA Landfilling and Potential On-site Construction Dewatering, Treatment, and Disposal. Alternative SC-1 - No Action/Institutional Controls This alternative was evaluated in detail in the FS to serve as a baseline for comparison with the other remedial alternatives under consideration. Under this alternative, no treatment or containment of disposal areas would occur. This alternative does include fencing and deed restrictions for the property, and also includes a long-term monitoring program. This alternative would not meet the source control remedial objectives for the site. Estimated Estimated Estimated Estimated Estimated time for design and construction: 2 months period for operation: 30 years capital cost: $174,400 operation and maintenance cost (net present worth): $2,948,315 total cost (net present worth): $3,123,000 Alternative SC-2A - Sediment and Landfill Consolidation, Landfill Capping, and On-site Groundwater Treatment and Disposal for Construction Dewatering This alternative involves excavation and consolidation of: 1) sediments containing contaminants at levels in excess of established treatment goals, and 2) landfill debris and contaminated soils that would otherwise remain in contact with groundwater after landfill capping. During excavation, air emissions would be controlled with synthetic covers, such as geomembranes. Also during construction, the excavation would be dewatered via a system of advancing well points. Extracted groundwater would be treated in an on-site mobile unit to meet site-specific groundwater treatment goals (either risk-based, or based on federal/state groundwater MCLs). These goals will be met via multimedia filtration, ion exchange, and activated carbon adsorption. Treated water would be discharged to the local POTW via existing sewer lines. Therefore, treated water would meet Federal Clean Water Act (CWA, 40 CFR 403) pretreatment standards for discharge to a POTW. In addition, the treated water would meet New Hampshire pretreatment standards, per Env-Ws 900, Part 904.07, as well as requirements imposed by the local POTW. Following consolidation, the landfill would be capped with a composite-barrier-type cap. A security fence and deed restrictions would be used to prevent unauthorized access and future activities that could compromise the composite-barrier cap integrity. Based on the MODFLOW model, approximately 53,500 yd[3] of saturated landfill material would require consolidation. The total excavated volume is estimated at 145,500 yd[3]. Additionally, sampling results suggest that a total sediment volume of 9,600 yd[3] would require consolidation. The additional LF-2/LF-4 debris, which will also be consolidated on LF-5 (see Sections IV and XII), would increase the total excavated volume by approximately 76,320 yd[3]. This is an increase of greater than 100% in volume. However, when this volume is partially used to fill the excavation at LF-5, and partially spread over an area of 28 acres on top of LF-5, cap design and final grading are unaffected. Additional volumes from LF-2/LF-4 and additional costs (if any) associated with placement of LF-2/LF-4 soils and debris on LF-5 are discussed in the Proposed Plan for LF-2/LF-4 completed in July 1993. Risks posed by exposure to contaminated sediments, soils, and debris would be eliminated as soon as the cap is in place. This would also minimize the potential for LF-5 to act as a source of surface water and groundwater contamination by reducing the mobility of contaminants in the landfill materials and sediments. All soil, sediment, and air applicable or relevant and appropriate requirements (ARARs) would be met. Treatment residuals, including concentrated salt solution and iron sludge, would be disposed of off-site. Spent activated carbon would be transported off-site for regeneration or disposal. For implementation of Alternative SC-2A, acquisition of approvals from and coordination with the New Hampshire Wetlands Board and NHDES would be required. Quarterly air monitoring and bi-annual groundwater modeling would be required. Per CERCLA guidance, the monitoring is estimated to continue for a period of 30 years (for costing purposes), with the understanding that continued monitoring or other remedial actions subsequent to the 30-year period, are the responsibility of the Air Force. Five-year reviews to assess performance of the containment system would also be needed. Estimated Estimated Estimated Estimated Estimated time for design and construction: 1 year time of operation: 30 years capital cost: $17,362,700 operation and maintenance cost (net present worth): $6,629,721 total cost (net present worth): $23,992,000 Alternative SC-3A - Excavation and Consolidation of Sediments on Landfill, Landfill Capping, and On-site Landfill Waste Dewatering, Treatment, and Disposal Under Alternative SC-3A, excavation and placement of an estimated 9,600 yd[3] of contaminated sediments and regrading and capping the existing landfill would occur as described for Alternative SC-2A. No landfill excavation would be performed; however, landfill debris would be dewatered. Dewatering would occur such that-the post-capping water table would be lowered to a level 2 feet below the debris. This difference would minimize some of the short-term impacts associated with landfill excavation; however, it would require long-term groundwater extraction and possibly treatment in order to keep the waste dewatered. The dewatering strategy is based on water-table elevations predicted by the MODFLOW model. The dewatering system would consist of six extraction wells and a collection trench. The combined groundwater extraction rate for the six wells is expected to average 45 gallons per minute (gpm). The bottom of the collection trench would be set at 80 feet above mean sea level (MSL). The extracted groundwater would be treated via lime precipitation and carbon adsorption. Flow rates to the treatment system would average 45 gpm, with a maximum anticipated flow rate of 60 gpm. The treatment system would be enclosed to prevent freezing during winter months. Treated effluent would be discharged to the local POTW, as specified for Alternative SC-2A. Residuals generated from the groundwater treatment system include spent carbon (it is anticipated that two 2,200-pound units would be employed in series), and approximately 11.25 tons per year of hydroxide/carbonate sludge. Treatability studies would be required for verification of these residuals amounts. It is anticipated that the sludge will pass the Toxicity Characteristic Leaching Procedure (TCLP) tests; however, dewatered sludge would have to be analyzed to verify this, in accordance with the Resource Conservation and Recovery Act (RCRA). Sludge would be disposed of off-site in accordance with state and federal regulations. Spent carbon would be regenerated off-site. Treated water would meet the standards for discharge to the local POTW, as described for Alternative SC-2A. Long-term monitoring of on-site groundwater would continue for an estimated 30 years, as for Alternative SC-2A, with the same provisions for extended monitoring or remedial actions, as necessary. As with Alternative SC-2A, institutional controls such as fencing and deed restrictions, would be necessary. Monitoring of groundwater levels within the landfill would be required to ensure that the dewatering system was maintaining water levels beneath the waste material. Estimated Estimated Estimated Estimated Estimated time for design and construction: 1 year period for operation: 30 years capital cost: $13,084,000 operation and maintenance cost (net present worth): $10,916,337 total cost (net present worth): $24,000,000 Alternative SC-4D - Sediment and Landfill Consolidation, Hot Spot Thermal Treatment On-site, Landfill Capping, and Potential On-site Construction Dewatering, Treatment, and Disposal Under this alternative, excavation and consolidation of sediments and landfill debris predicted to be below the water table would be conducted in the same manner as for Alternative SC-2A. The volumes of sediment and landfill material excavated and consolidated would be 9,600 yd[3] and 53,500 yd[3], respectively. Details on consolidating, regrading, and capping of the existing landfill as well as environmental monitoring and placement of institutional controls would be the same as for Alternative SC-2A. Groundwater collected during construction dewatering would be treated and discharged to the local POTW as with Alternative SC-2A. The same type and amount of treatment residuals would be produced and these would be disposed of off-site as described for Alternative SC-2A. Treatment goals and ARARs are expected to be met as with Alternative SC-2A, and the same long-term monitoring requirements as for Alternative SC-2A are anticipated. The only significant difference in the activities posed in Alternative SC-4D versus Alternative SC-2A is the thermal treatment of hot spot soils and the placement of treated residuals back into the landfill. The hot spot soils to be treated include several areas in the drum disposal area which, after drum and tank removal operations, were found to contain high concentrations of contaminants of concern, most notably PAHs. Thermal treatment has been proposed for these soils to reduce the overall toxicities and quantities of LF-5 contaminants. For treatment, the Low Temperature Thermal Treatment system (LT[3]) or its equivalent would be used. As part of the LT[3] process, during soil excavation, field screening would be conducted to determine whether elevated PAH levels remain. Additionally, periodic TCLP analyses of the contaminated soil would be performed to ensure that RCRA LDRs would be met. It is possible that by the time remediation is initiated, the final rule for contaminated soils will become final. In this instance, thermal treatment would be the only LDR compliance necessary. Otherwise, a treatability variance from EPA may be required such that existing LDR treatment standards can be satisfied. Currently, treatment goals are based on current hot spot data and a projected removal efficiency of 95% for the LT[3] system. Treatability studies may be required if a more accurate removal efficiency is required. If LF-5 receives a CAMU designation (see Sections IV, IX, and X), LDRs would not apply to this alternative. Air monitoring would be required throughout hot spot soils excavation and treatment activities, as would institutional controls for minimization of short-term human health risks posed during excavation. Following treatment, TCLP soil analyses would be conducted on the residuals to ensure that metals have not been concentrated or their solubilities changed such that TCLP criteria are exceeded. If TCLP criteria are exceeded, pozzalonic stabilization of residuals will be performed prior to landfilling in order to reduce contaminant leachability (mobility). Estimated Estimated Estimated Estimated Estimated time for design and construction: 2 years period for operation: 30 years capital cost: $23,526,400 operation and maintenance cost (net present worth): $6,605,687 total cost (net present worth): $30,132,000 Alternative SC-5A - Sediment and Landfill Waste On-site RCRA Landfilling and Potential On-site Construction Dewatering and Disposal In this alternative, all of the landfilled solid waste would be excavated and placed into a secure RCRA Subtitle C landfill on-site. Sediment excavation activities, on-site treatment of groundwater for construction dewatering, and environmental monitoring would be performed as described for Alternative SC-2A. The facility would be designed to hold, at a minimum, the 251,000 yd[3] of solid waste estimated to be landfilled. In addition, the facility should have the capacity to hold an estimated 70,000 yd[3] of soil from below the existing waste deposits, and an estimated 19,000 yd[3] of thickened sediments, plus an allowance of 17,000 yd[3] for intermediate cover soil. The new landfill would be constructed to RCRA Subtitle C standards. It would have a double-composite bottom liner system, providing for leachate collection and leak detection. A perimeter containment berm, constructed of selected earthen materials, would define the lateral limits of the lined facility. On completion of filling, the landfill would be capped with a multilayered composite final cover system, such as that described for Alternative SC-2A. The maximum elevation of the new landfill would be 140 (+-) feet MSL, based on a contained volume of about 390,000 yd[3] (including 150,000 yd[3] of excavated material). This elevation would be approximately 40 feet above the maximum elevation of the present site. To achieve that height, the sides of the landfill would rise at a slope not exceeding 3:1 (horizontal:vertical) to about elevation 130. Above elevation 130, top slopes would be at a minimum of 20:1 (5%). Construction of the RCRA Subtitle C landfill, including dewatering, excavation, stockpiling filling, grading, liner and leachate collection systems, waste placement and compaction, and composite cap construction, would be expected to require approximately 2 years. Leachate generated from the landfill would be collected in a wet well and would be pumped into an aboveground storage system. Off-site treatment and disposal of leachate will be performed, as required. Eventually the leachate could be processed through a groundwater treatment plant constructed on the base. Leachate generation has been estimated at between 1,400 and 2,100gallons per day (gpd) based on a preliminary evaluation of the proposed landfill conditions. It has been assumed that the leachate would be treated off-base for the first 5 years of operation and at a plant constructed on the base after that time. Similar to Alternatives SC-2A and SC-4D, groundwater extracted during construction dewatering would be treated on-site with a mobile treatment plant. In this alternative, the mass of contaminants treated would be greater than for Alternatives SC-2A and SC-4D since more extensive dewatering would be conducted. Ion-exchange salt solution and iron sludge from the mobile treatment plant would be disposed of off-site. Activated carbon used in the groundwater treatment plant (GWTP) would be transported off-site for regeneration. No residuals associated with soil handling and capping activities are expected to be produced. It was assumed that 0.5% of the landfill material would require off-site treatment to comply with ARARs; all other waste materials would be incorporated into the RCRA Subtitle C landfill. Risks to human and ecological receptors via exposure to the waste materials, sediment, and surface soils would be minimized under this alternative. Containment of waste materials in the lined facility and collection of leachate for off-site treatment would eliminate potential contributions to groundwater that would exist for all other alternatives. This alternative may help achieve groundwater ARARs more quickly than Alternatives SC-1, SC-2A, SC3A, and SC-4D because of the complete isolation of source contaminants and a reduction in the volume of contaminated groundwater present at the site that would be effected during construction dewatering activities. As in the previous capping alternatives (SC-2A, SC-3A, and SC-4D), indirect treatment of the landfilled material would occur through natural biotransformation and desorption processes within the landfill. These processes may reduce the toxicity of the waste materials. In contrast to the previous capping alternatives, however, contaminants leached from soil and debris by water infiltrating the cap would be collected and treated off-site, thereby reducing the TMV of contaminated leachate. Predicted air emissions from the landfill are expected to be less than EPA's proposed action level of 150 mg/year (above which active control of emissions is required), but air monitoring would be conducted to ensure compliance with federal and state requirements for hazardous and toxic air pollutants. Monitoring of the volume of leachate generated from the bottom collection system of the landfill would evaluate the effectiveness of the inner geomembrane liner. Groundwater quality monitoring around the landfill for conventional leachate parameters would be used to evaluate the entire landfill's containment effectiveness. Periodic sampling and analysis of groundwater around LF-5 for conventional leachate parameters would be conducted as part of the long-term groundwater monitoring program. This program would evaluate the effectiveness of the RCRA cell in containing site contaminants. Coordination and consultation with NHDES would be required for this alternative. Acceptance by the Waste Management Division would be expected. Coordination and consultation with the New Hampshire Wetlands Board would be expected because of activities in and around wetland areas. It is also expected that consultation with the Water Supply and Pollution Control Division of NHDES would be required concerning the effluent discharge from the GWTP. Consultation and coordination with the Air Resources Division of NHDES may also be required because of potential odor and particulate emissions from the excavation areas and stockpiled waste materials. Estimated Estimated Estimated Estimated Estimated IX. time for design and construction: 2 years period for operation: 30 years capital cost: $28,813,600 operation and maintenance cost (net present worth): $11,461,724 total cost (net present worth): $40,275,000 SUMMARY OF THE COMPARATIVE ANALYSIS OF ALTERNATIVES Section 121(b)(1) of CERCLA presents several factors that must be considered when assessing alternatives. Building on these specific statutory mandates, the NCP articulates nine evaluation criteria to be used in assessing the individual remedial alternatives. A detailed analysis was performed on the alternatives using the nine evaluation criteria in order to select a site remedy. The following is a summary of the comparison of each alternative's strengths and weaknesses with respect to the nine evaluation criteria. These criteria are summarized as follows: Threshold Criteria The two threshold criteria described must be met in order for the alternatives to be eligible for selection in accordance with the NCP. 1. Overall protection of human health and the environment addresses whether or not a remedy provides adequate protection and describes how risks posed through each pathway are eliminated, reduced, or controlled through treatment, engineering controls, or institutional controls. 2. Compliance with ARARS addresses whether or not a remedy will meet all of the ARARs of other federal and state environmental laws and/or provide grounds for invoking a waiver. Primary Balancing Criteria The following five criteria are utilized to compare and evaluate the elements of one alternative to another that meet the threshold criteria. 3. Long-term effectiveness and permanence address the criteria that are utilized to assess alternatives for the long-term effectiveness and permanence they afford, along with the degree of certainty that they will prove successful. 4. Reduction of toxicity, mobility, or volume through treatment addresses the degree to which alternatives employ recycling or treatment that reduces toxicity, mobility, or volume, including how treatment is used to address the principal threats posed by the site. 5. Short-term effectiveness addresses the period of time needed to achieve protection and any adverse impacts on human health and the environment that may be posed during the construction and implementation period, until cleanup goals are achieved. 6. Implementability addresses the technical and administrative feasibility of a remedy, including the availability of materials and services needed to implement a particular option. 7. Cost includes estimated capital and operation and maintenance (O&M) costs, as well as present-worth costs. Modifying Criteria The modifying criteria are used on the final evaluation of remedial alternatives generally after public comments on the RI/FS and Proposed Plan are received. 8. State acceptance addresses the state's position and key concerns related to the preferred alternative and other alternatives, and the state's comments on ARARs or the proposed use of waivers. 9. Community acceptance addresses the public's general response to the alternatives described in the Proposed Plan and RI/FS report. Community acceptance of both the original and the revised Proposed Plans for LF-5 was evaluated based on written comments and verbal comments received in public meetings during the public comment period. Detailed tabular assessments of each alternative according to the threshold and balancing criteria can be found in Tables 5.2-1 through 5.2-6 of the FS. Following the detailed analysis of each individual alternative, a comparative analysis, focusing on the relative performance of each analysis against the threshold and balancing criteria, was conducted. This comparative analysis can be found in Table 15. The following subsection presents the nine criteria, including the two modifying criteria not discussed in the FS, a brief narrative summary of the alternatives and the strengths and weaknesses according to the detailed and comparative analysis. A. Overall Protection of Human Health and the Environment In the long term, Alternative SC-1 would minimize the exposure of humans and large animals to landfill soil, solid wastes, and surrounding sediment by restricting site access and development. However, site worker and small animal exposure would not be mitigated. In addition, contaminant leaching to groundwater would continue, thereby, allowing human exposure via potential groundwater use as well as through recreational uses of drainage channels to which a portion of groundwater and overland flows discharge. The continued leaching of contaminants would also affect wetlands habitats at LF5. Alternatives SC-2A, SC-3A, SC-4D, and SC-5A would achieve overall protection of human and ecological receptors from contaminated soils and sediments. These four alternatives would also contribute to attainment of overall Zone 1 groundwater and surface water objectives. For each of the four alternatives, protection of human and ecological receptors from surface water contaminants is expected over the long term, due to elimination of leachate and contaminated sediments as sources. Alternative SC-5A would further reduce the potential for contaminant migration to groundwater and surface water over that of the other alternatives by encasing all landfill wastes in a RCRA cell. Over the short term, groundwater use restrictions would be necessary to mitigate risks associated with groundwater use in the early stages of remediation. B. Compliance with ARARs Complete ARAR compliance would not be attained for Alternative SC-1 due to the lack of remediation planned for that alternative. Of the three types of ARARs (location-specific, action-specific, and contaminant-specific), location-specific ARARs are the only ARARs for which compliance would be attained. Alternatives SC-2A, SC-3A, SC-4D, and SC-5A would all be expected to achieve compliance with locationand action-specific ARARs. For contaminant-specific ARARs, all four alternatives would meet soil, sediment, and air ARARs. C. Long-Term Effectiveness and Permanence The deed restrictions and site access restrictions in Alternative SC-1 would reduce, but would not prevent, human contact with contaminated soils, sediments, surface water, and groundwater. Exposures to ecological receptors would not be mitigated. In addition, no reduction in contaminant TMV would be achieved. Therefore, continued human and ecological receptor exposure is expected over the long term. For Alternatives SC-2A, SC-3A, SC-4D, and SC-5A, significant risk reduction is achieved by eliminating dermal and ingestion exposure routes (both human and ecological receptors) to contamination in site soils and sediments from LF-2, LF-4, and LF-5. For all four alternatives, it is expected that long-term reliability would be enhanced via periodic inspections, and management and monitoring for a period of 30 years (this time-frame is typically chosen for costing purposes). For Alternative SC-3A, it is assumed that groundwater would require treatment for a period of 30 years to maintain long-term effectiveness. Additionally, pursuant to the requirements of CERCLA 120(h)(3)(B)(ii), should any additional remedial actions be required (including continued monitoring) either during or subsequent to the 30-year time period, the Air Force will be responsible for implementation of these actions, regardless of when the need arises. This ensured the long-term effectiveness of Alternatives SC-2A, SC-3A, SC-4D, and SC-5A subsequent to the 30-year monitoring and treatment periods described. There exists a potential for future receptor exposures to site contaminants due to failure of the containment strategy-cap failure for Alternatives SC-2A, SC-3A, SC-4D, and SC-5A. Each source control alternative would contribute to attainment of overall Zone 1 objectives for groundwater and surface water. D. Reduction of Toxicity, Mobility, or Volume Through Treatment Alternatives SC-1 would not reduce the TMV of contaminants through treatment because the alternative does not provide for treatment. Each of the remaining alternatives, Alternatives SC-2A, SC-3A, SC4D, and SC-5A would provide for some degree of reduction in TMV, but would not significantly reduce TMV as a principal element of the remedy. All four alternatives would reduce TMV for groundwater currently in contact with solid waste. This would serve to reduce the mobility of soil contaminants in LF-2, LF-4, and LF-5. In the case of Alternative SC-5A, which provides for on-site RCRA landfilling of contaminated soils and sediments, reduction in the mobility of soil contaminants would be significantly increased over the other three alternatives. For Alternative SC-4D, reduction of the TMV of hot spot soils via thermal treatment (LT[3]) would be achieved. All four alternatives (SC-2A, SC-3A, SC-4D, and SC-5A) involve onsite groundwater treatment, which constitutes irreversible treatment. All four alternatives will produce groundwater treatment residuals (either concentrated ion salt solution, iron sludge and spent carbon, or carbonate and metal hydroxide sludge and spent carbon). In each case, off-site disposal/regeneration is expected. Thermal treatment residuals (Alternative SC-4D) would be tested for TCLP criteria and to determine the percent contaminant destruction achieved prior to placement back in the excavation. E. Short-Term Effectiveness Implementation of Alternative SC-1 would not be expected to have significant impacts on the community. In addition, impacts to workers would not be expected, and use of personal protective equipment (PPE) would minimize potential impacts during fence and wall installation and water sampling activities. Minor environmental impacts would be possible during implementation, and would be mitigated via use of erosion control measures. The total time for implementation of Alternative SC-1 is estimated to be 2 months. Each of the four remaining alternatives (SC-2A, SC-3A, SC-4D, and SC-5A) would result in potential community and worker exposure to emissions generated during remedial activities (landfill excavation Alternatives SC-2A, SC4D, SC-5A; thermal treatment - Alternative SC-4D; groundwater treatment Alternative SC-3A). These impacts would be minimized using engineering controls and site-specific health and safety procedures. Sediment excavation and landfill dewatering during implementation of Alternatives SC-2A, SC-4D, and SC-5D could impact wetlands environments at LF-5. Long-term groundwater extraction during implementation of Alternative SC-3A could result in even greater impacts. Landfill capping could compound the effect by reducing groundwater recharge in the area (Alternatives SC-2A, SC-3A, and SC-4D). Installation of a RCRA landfill (Alternative SC-5A) could further exacerbate the problem. In all cases, wetlands mitigation may be performed as part of remedial activities. F. Implementability Alternative SC-1, with its minimal construction activities, is easily constructed and is not hindered by site conditions. Monitoring and maintenance activities would be easily performed. Composite barrier cap construction, as planned for Alternatives SC-2A, SC-3A, and SC-4D, is a proven and well-known technology. Site conditions are not expected to inhibit construction. Composite-barrier caps are considered reliable engineering controls. Cap construction would have to be limited to warmer months, and modeling would be required to better predict the post-capping water table elevation. More comprehensive modeling and pilot-scale treatability studies would likely be required for Alternative SC-3A due to the expected long-term groundwater pumping and on-site treatment planned. Thermal treatment (Alternative SC4D) is a proven and well-known technology and should not be adversely impacted by site conditions. However, there would be some difficulties associated with materials handling and low throughput rates due to potentially high soil moisture content. Construction of a RCRA landfill (Alternative SC-5A) is a proven and well-known technology. However, site conditions, such as bedrock and water table elevation, actual volume of wastes to be landfilled, and the necessity to import construction fill material could hinder construction. As with Alternatives SC-2A and SC-4D, groundwater treatment for construction dewatering is a well known and reliable technology that is not difficult to implement. All five alternatives (SC-1, SC-2A, SC-3A, SC-4D, and SC-5A) would potentially require acquisition of permits/approvals for implementation. In addition, all alternatives would require some degree of monitoring and maintenance activities. In each case, the activities are easily performed. G. Cost The estimated present worth value of each alternative and the options are as follows: H. State Acceptance NHDES has been involved in the environmental activities at Pease AFB since the mid-1980s, as summarized in Section II of this document. The RI was performed as an Air Force lead, with state and EPA oversight, in accordance with the FFA. NHDES has reviewed this document and concurs with the selected remedy. A copy of the Declaration of Concurrence is attached as Appendix B. I. Community Acceptance The comments received during the public comment periods and the public hearings on both the original and revised LF-5 Proposed Plans are summarized in the attached document entitled "The Responsiveness Summary" (Appendix C). The selected remedy has been modified from that presented in the original Proposed Plan based on public comment, as described in Section X. X. THE SELECTED REMEDY The selected remedy is comprehensive in that it provides for source control and reduction of exposure to site contaminants via containment, and it also contributes to attainment of overall Zone 1 objectives (to be presented at a later date in the Zone 1 FS) of migration control for surface water and groundwater. The selected remedy, Alternative SC-2A, involves excavation and consolidation of sediments, which contain levels of contamination in excess of selected cleanup levels, on LF-5. Landfill debris from LF-5 that was predicted to be saturated after capping (as determined via MODFLOW modeling) would also be excavated and consolidated on LF-5. In addition, LF-2 and LF-4 soil and debris would be excavated and consolidated on LF-5 (see Sections IV and XII). However, since LF-2 and LF-4 are part of the Zone 1 operable unit, final decision under the Zone 1 ROD will be required prior to implementation of the proposed excavation and consolidation plan for LF-2 and LF-4. Following consolidation, the landfill would be covered with a composite-barrier type cap to prevent water infiltration. During construction, in order to facilitate excavation, groundwater would be collected and treated in a temporary on-site mobile system. Discharge of treated water to Flagstone Brook was specified in the original Proposed Plan. Based on public comment to the original Proposed Plan, this strategy was revised to specify discharge to the local POTW via the sanitary sewer. A. Methodology for Cleanup Level Determination Cleanup levels have been selected for each medium of concern at LF5. Cleanup levels have been established for chemicals of concern identified in the risk assessment section of the LF-5 Draft Final RI Report and for contaminants detected at levels exceeding ARARs or risk-based concentrations. The approach human health approach was NHDES. This used to determine risk-based concentrations is consistent with the approach used to evaluate risk in the risk assessment section of the LF-5 Draft Final RI Report (F-500). This originally presented in a protocols document submitted to EPA Region I and document was subsequently amended and a revised version was resubmitted. Risk-based concentrations were derived for the chemicals of concern in each medium, based on the most reasonable maximally exposed human receptor (current or future) for the medium. The chemicals of concern include those substances that were identified as chemicals of concern in the risk assessment section of the LF-5 Draft Final RI Report (F-500). In addition, risk-based concentrations were derived for a few chemicals that were not selected as chemicals of concern in the RA, but whose maximum reported concentration exceeded one or more ARAR. Risk-based concentrations were derived for each noncarcinogenic chemical in a medium based on a goal of a hazard index of 1. For each carcinogenic chemical, the concentrations were derived based on a goal of 10[-6] (1-in-1 million) lifetime cancer risk, with the following exceptions. Some chemicals, although categorized by EPA as carcinogens, are not considered to be carcinogenic through all exposure routes. For example, several metals, including cadmium, chromium (VI), and nickel, are not classified as carcinogens through the oral exposure route. Therefore, in deriving risk-based concentrations for a given medium, if a carcinogenic chemical was not considered to be carcinogenic through the applicable exposure routes, the risk-based concentration for the chemical was based on a hazard index of 1 (i.e., noncarcinogenic risk). Cleanup levels were selected after comparing maximum contaminant concentrations detected for each contaminant of concern in each medium with appropriate chemical-specific ARARs, human health, and, if applicable, ecological risk-based concentrations. In general, where ARARs were available and deemed appropriate, the ARARs were selected as cleanup levels. Where ARARs were not available, or if the basis on which the ARAR was established was not consistent with LF-5 exposure scenarios, a risk-based concentration was selected as the cleanup goal. When ARARs were selected as the cleanup goal a human health risk was calculated for the ARAR concentration. Cleanup levels were not established for chemicals detected at maximum concentrations that were lower than appropriate ARARs or risk-based concentrations. Cleanup levels for the various contaminated media at LF-5 are summarized in the subsections that follow. B. Groundwater Cleanup Levels/Treatment Goals The selected remedy for LF-5 does not address groundwater beneath and in the vicinity of LF-5. Contamination in groundwater will be addressed in the Zone 1 FS, Proposed Plan, and ROD. However, the LF-5 source control remedy would be expected to contribute to attainment of the Zone 1 objectives and cleanup goals via removal of contaminant sources and would facilitate the implementation of potential groundwater actions that will be evaluated during the Zone 1 RI/FS process. For the purposes of this ROD, the Zone 1 cleanup levels are to be considered (TBC) guidelines for treatment of groundwater extracted for construction dewatering purposes. Treatment requirements established in the state, federal, and local POTW pretreatment standards will serve as ARARs. Table 16 presents ARARs, risk-based concentrations, maximum average detected concentrations in groundwater, and selected cleanup levels for contaminants detected in groundwater. The cleanup levels were calculated using the Zone 1 objectives for groundwater. C. Landfill Soil and Solid Waste Cleanup Levels Table 17 presents human health and ecological risk-based concentrations, maximum detected concentrations, and selected cleanup levels for contaminants detected in soils in the landfill, including the hot spots. Cleanup levels were established for 22 contaminants in the landfill (excluding hot spot soils) detected at concentrations exceeding either human health or ecological risk-based concentrations. The majority of cleanup goals were ecological risk-based concentrations. Ecological risk-based concentrations were developed as described in Subsection 2.3 of the LF-5 FS. Cleanup goals were also established for contaminants in the drum removal area hot spot soils. Again, most of the cleanup goals were ecological risk-based concentrations. Drum removal area hot spot contaminants for which cleanup levels were established include seven pesticides, one SVOC, 10 PAHs, and four metals. Cleanup levels were not established for any contaminants in the staged UST location hot spot. D. Sediment Cleanup Levels Table 18 presents human health risk-based concentrations, maximum concentrations detected in sediment, and TBC criteria that were used in determining ecological risks. These TBC criteria are the NOAA biological effects levels (ER-Ls) established by Technical Memorandum NOS OMA 52, March 1990. While NOAA sediment guidelines are not enforceable and, consequently, are not considered ARARs, they appear to be appropriate toxicity benchmark values and were used in deriving ecological risk-based cleanup levels. In all cases, these TBCs were selected as sediment cleanup goals. As a result, cleanup goals were established for five pesticides, seven PAHs, and five metals in the Railway Ditch, and for three pesticides and two metals in Flagstone Brook. As described in Subsection 2.1 of the LF-5 Draft Final FS, remediation of sediment in Flagstone Brook will be an objective of the Zone 1 remedy. It should be noted that DDE, DDD, and DDT were detected in most sediment samples collected at Pease AFB and may be indicative of background levels. Human health risk-based concentrations were typically orders of magnitude greater than the NOAA criteria and were not used to select cleanup goals. As shown in Table 2.4-2 of the FS, there are no human health risks associated with these ecologically based TBC sediment criteria. E. Surface Water Cleanup Levels Table 19 presents ecological risk-based ARARs, human health risk based concentrations, maximum detected concentrations, and cleanup levels for contaminants detected in surface water in the Railway Ditch. The cleanup goals were derived to satisfy the Zone 1 Railway Ditch RAOs. As discussed previously, the LF-5 source control remedy would be expected to contribute to attainment of the Zone 1 objectives and cleanup goals. All cleanup goals were based on New Hampshire surface water standards that are protective of aquatic life. Chronic criteria were used to evaluate ecological risks in the baseline RA and therefore, are selected as the applicable ARARs for Zone 1. Cleanup levels were established for one pesticide, 10 metals in the Railway Ditch, and one pesticide and four metals in Flagstone Brook. Human health risks associated with Zone 1 ARAR concentrations selected as cleanup goals are presented in Table 2.4-7 of the LF-5 Draft Final FS. As shown in the table, cancer risks greater than 10[-6] exist due to the use of ARARs as cleanup goals for DDT, 1,4-dichlorobenzene, and TCE. The maximum residual cancer risk was for TCE (2.15 x 10[-5]). No excess noncancer human health risks would result. F. Description of Remedial Components The chosen LF-5 remedy, whose main remedial goal is source control, will involve the following key components: • Excavation and consolidation of Railway Ditch sediments that contain contaminants at concentrations exceeding site-specific cleanup goals. A mobile laboratory will be on-site to confirm the removal of contaminated material. The excavated material will be dewatered and bulked, if necessary, and consolidated on LF-5. • Landfill debris that would still be in contact with groundwater after capping will be excavated and consolidated on dry locations on the landfill prior to capping. The excavation will be backfilled with clean fill to a level at least 2 feet above the natural groundwater table after capping and excavated waste will be placed above the clean fill. • The LF-5 debris excavation area will be dewatered, as necessary, during the excavation process (i.e., the groundwater table will be artificially lowered rendering the area to be excavated dry). Any groundwater extracted as part of the dewatering process will be treated in an on-site mobile treatment unit to meet site specific groundwater treatment objectives. Treated groundwater will be discharged to the local POTW via the sanitary sewer. • Soil and waste materials from LF-2 and LF-4 will be consolidated on LF-5. A final decision under CERCLA for LF-2 and LF-4 will be required prior to implementation of the proposed consolidation plan for LF-2 and LF-4. • Following consolidation of all wastes, including material from LF-2 and LF-4, the landfill will be capped with a composite barrier cap, which will meet performance standards required in a RCRA cap. As part of the cap construction, a passive gas collection system will be installed to capture and vent landfill gases. It is estimated the cap will cover the entire landfill, an area of approximately 1.2 million square feet. Deed restrictions will be imposed to restrict future construction activities that could violate the integrity of the cap. • The remedial action will be monitored to ensure that the integrity of the cap is maintained as well as monitoring groundwater elevation to ensure that the waste material remains dry. • Five-year reviews would be required as part of the environmental monitoring program. The 5-year reviews would assess the performance of the containment system and make recommendations, as appropriate, regarding additional remedial action. Figure 9 provides a remedial process flow sheet for the selected remedy that depicts the elements described. Detailed descriptions of the various components follow. Sediment excavation and consolidation on LF-5 would be performed in a phased approach. Sediments would first be excavated and placed on compacted soils adjacent to the Railway Ditch. These activities will be conducted in accordance with the requirements of Env-Ws 415. During excavation, silt fences, hay bales, and other erosion control measures would be used for control or erosion and runoff. Following excavation, the sediments would be transported to a central staging area for thickening. Thickening would involve mixing the sediments with sandy soil in a 1:1 ratio. The use of heavy equipment and engineering controls, such as containment, during thickening would be facilitated by the installation of a concrete pad within the staging area. Following thickening, sediments would be placed on LF-5 for compaction, along with excavated landfill debris, prior to landfill regrading and capping. As described in Section VII of this ROD, it is anticipated that 3,200 yd[3] of sediments from the Railway Ditch will be excavated and consolidated, according to the method presented previously. In addition, it is currently believed that a total of 6,600 yd[3] of sediments from two site wetlands may require similar remediation. During remedial design, available data (including additional Stage 4 data) will be used to refine this estimate, as well as to determine the potential for and magnitude of harmful environmental effects resulting from wetlands excavation. During remedial design, it will be determined whether excavation in a particular wetland would result in more harm to the ecosystem and greater human health risks than can be justified by the expected contaminant reduction. Since excavation would result in destruction of portions of the affected wetlands, excavation will be avoided wherever possible. The remedial design also will include wetlands restoration or formation of new wetlands, as necessary. Currently, restoration of the Railway Ditch following excavation is not anticipated. The ditch will likely be allowed to stabilize and revegetate naturally. The necessity for immediate stabilization and revegetation will be reevaluated, if during remedial design, it becomes apparent that regrading and capping actions at LF-5 would adversely impact the ditch. This alternative also involves excavation and consolidation of landfill soil and debris predicted to be in contact with groundwater or within 2 feet above the groundwater table as it would exist following capping of LF-5. Available groundwater elevation data were used in conjunction with the MODFLOW model to predict what portion of landfill soils would require excavation under this scenario. All excavated materials would initially be stockpiled within a bermed area atop the landfill. The MODFLOW model estimates the volume of excavated soil and debris at a total of 145,500 yd[3], approximately 92,000 yd[3] of which represents unsaturated materials that are to be returned to the landfill following placement of clean fill to 2 feet above the water table. The remaining 53,500 yd[3] would be consolidated on the landfill. Material from LF-2 and LF-4 will also be consolidated on LF-5 prior to capping. The quantities of this material were estimated to be approximately 76,320 cubic yards from LF-2 and LF-4 combined. Consolidation of this additional material onto LF-5 is not expected to significantly change the cap design criteria originally presented in the FS. During excavation/consolidation activities, erosion runoff and odor and particulate emissions would be controlled via the use of a temporary runoff detention basin adjacent to the stockpile, and placement of geomembranes on the stockpile and sideslopes of the excavation areas. Continuous onsite air monitoring will also be conducted during excavation. Construction activities during landfill debris excavation and consolidation may be facilitated via dewatering of the excavation below the static water table. A system of well points would be installed, which would allow groundwater extraction at an average rate of approximately 50 gpm. Following extraction, groundwater would be treated in a mobile on-site unit composed of multimedia filtration, ion exchange, and activated carbon adsorption units. Runoff from the stockpile would also be treated in the mobile unit. Treated effluent would comply with MCLs and federal, state, and local requirements for discharge to a POTW. As such, treated water will be: 1) discharged to the local POTW via sanitary sewer lines, or 2) used for site dust control (see Figure 9, for a schematic). Subsequent to consolidation of sediments and landfill materials on LF-5, the landfill would be capped with a composite barrier that would meet RCRA performance standards. The cap would consist of the following (from bottom to top): • A subbase/gas ventilation layer, consisting of a 12-inch lift of sandy soils placed on a graded and compacted 12-inch layer of intermediate soil overlying the landfill. Decomposition gases would be vented via passive gas vents constructed of perforated and solid walled plastic pipe. The vents would be installed at 200-foot intervals through the final cover and linked to the sand subbase layer, which would aid in the interception and transmission of gases to the vents. A geotextile would overlie the sand layer and would serve as a bedding layer for the overlying composite barrier. • A composite barrier layer, consisting of a clay mat overlain by a 40-mil, very low density polyethylene (VLDPE) geomembrane. The clay mat would be composed of bentonite clay bonded to a geomembrane or a geotextile. • A drainage composite layer, composed of a single-layer high-density polyethylene (HDPE) drainage net with a nonwoven needle punched geotextile. This layer would allow for water percolation, while preventing cover soil intrusion. • A protective cover layer, comprised of a minimum of 36 inches of drainage sand and 6 inches of mulched, seeded topsoil. This layer would provide protection against erosion and frost penetration. The drainage composite layer and its underlying geomembrane would be terminated in a perimeter anchor trench. The trench would be fitted with a subdrain of perforated plastic piping embedded in crushed stone. An estimated 18,000 yd[3] of perimeter landfill materials adjacent to the Railway Ditch and Flagstone Brook would be excavated and regraded to allow for appropriate construction of the anchor trench, drainage, access, and setbacks from site waterways. Figure 10 provides a schematic of the final cover system for the barrier cap at LF-5. The composite-barrier cap system would cover an estimated 28 acres. Final grading prior to capping would result in a minimum slope of 5% on top, and a maximum of 33% sideslope. Figure 11 depicts proposed final grades for the landfill barrier cap. Subsidence of the landfill surface would be monitored annually. Final grading may be contoured to blend with the surrounding topography. This grading will be presented in the remedial design. In addition, plans exist for construction of a North Ramp access road, by the PDA, which will traverse a portion of the LF-5 cap. The Air Force has worked and will work with the PDA in coordinating the design and construction activities for the cap and the access road. A figure depicting the planned layout of the access road can be found in the remedial design of Drawing No. 1, sheet 1 of 6, entitled "North Apron Access Road - Conceptual Design," by Hoyle and Tanner Associates. As with excavation activities, capping may result in destruction of wetlands adjacent to LF-5. (Potentially impacted wetlands are shown in Figure 12.) Mitigation of capped wetlands will involve construction of wetlands in non-wetlands areas. Appropriate wetlands reconstruction plans will be based on a wetlands function and value assessment conducted prior to commencement of construction activities. Groundwater will be monitored via sampling and analysis on a semiannual basis for an assumed duration of 30 years. This duration is typically assumed for costing purposes, per CERCLA guidance. As stated in Section IX, any future additional actions found to be necessary, regardless of when, will be conducted by the Air Force. Analysis would likely include VOCs, SVOCs, metals, nitrate, sulfate, chemical oxygen demand (COD), and other selected inorganics. In addition, pesticides and phenols would be monitored bi-annually. It is anticipated that surface water at LF-5 will undergo the same sampling regimen as groundwater, with the addition of biannual PCB analyses. Sediments would be analyzed semiannually for SVOCs and annually for VOCs, pesticides/PCBs, metals, sulfate, nitrate, and other inorganics. Sediments would be tested for phenols biannually. As with groundwater, surface water and sediment monitoring may continue for a period of 30 years. Specifics of the groundwater, surface water, and sediment monitoring programs will be finalized during remedial design. In addition to monitoring of ambient air at three stations on the landfill (upwind, downwind, central), soil gas monitoring along the LF-5 periphery would be conducted to monitor gas buildup beneath the cap. Approximately eight intermediate soil vents would be installed at locations between passive gas vents. In all cases, samples would be analyzed for methane and VOCs over a period of 30 years, unless annual evaluations of the monitoring program indicate that a change in the program is necessary. Five-year reviews of the containment system would be required for performance assessment and possible reevaluation and adjustments to the remediation program. Prior to implementation of Alternative SC-2A, pre-design studies would be required to more accurately determine design parameters. These studies would include: • Wetlands sampling for more accurate determination of design excavation volumes. • Additional groundwater modeling to more closely define the depth of the water table following capping. • Modeling of erosion/runoff from the cap to determine whether restoration of Flagstone Brook or the Railway Ditch (stabilization and revegetation) would be necessary. • Evaluation of sampling results for LF-2 and LF-4 to determine additional consolidated soil and debris volumes in the event that they are consolidated on LF-5. • Groundwater treatability studies for determination of mobile treatment unit design parameters. XI. STATUTORY DETERMINATION The remedial action selected for implementation at Pease AFB site is consistent with CERCLA and, to the extent practicable, the NCP. The selected remedy is protective of human health and the environment, attains ARARs or invokes appropriate waivers, and is cost-effective. The selected remedy does not satisfy the statutory preference for treatment that permanently and significantly reduces the mobility, toxicity, or volume of hazardous substances as a principal element. Additionally, the selected remedy utilizes alternative treatment technologies and resource recovery technologies to the maximum extent practicable. A. The Selected Remedy is Protective of Human Health and the Environment The remedy at this site will permanently reduce the risks posed to human health and the environment by eliminating, reducing, or controlling exposures to human and environmental receptors through treatment, engineering controls, and institutional controls; more specifically: • Excavation and consolidation of contaminated landfill soils and debris and contaminated sediments on LF-5, thereby eliminating leaching for contaminants to groundwater and reducing receptor exposure via containment. • Dewatering of landfill soils and debris during construction and treatment of water to reduce toxicity prior to discharge to a local POTW. • Capping of landfill to prevent water infiltration and reduce volume of leachate produced, and further reducing receptor exposure to contaminants. • Deed restrictions to prevent future construction that may pose a threat to cap integrity, thereby maintaining contaminant containment. Moreover, the selected remedy will achieve potential human health risk levels that attain the 10[-4] to 10[-6] incremental cancer risk range and a level protective of noncarcinogenic endpoints, and will comply with ARARs and other TBC criteria. B. The Selected Remedy Attains ARARs The selected remedy will attain all of the substantive, nonprocedural requirements of federal and state ARARs. ARARs for LF-5 are set forth in Table 20 contained in Appendix E of this document, which contains a complete list of ARARs including the regulatory citation, and a brief summary of the requirement, and the action to be taken to attain the requirement. The ARARs identified for LF-5 include: Chemical-Specific ARARs There were no chemical specific ARARs identified for the LF-5 selected remedy. Location-Specific ARARs • Fish and Wildlife Coordination Act (FWCA) • Executive Order 11990 (40 CFR 6, Appendix A), Protection of Wetlands • Floodplains Executive Order 11888 Minimization Of Flood Impacts And Protection of Beneficial Value of Floodplains • Clean Water Act, Section 404 (40 CFR 230; 33 CFR 320330), Prohibition of Wetland Filling • State of New Hampshire Administrative Code Env-Ws 415 Rules To Prevent Pollution From Activities In Or Near State Surface Waters • State of New Hampshire Administrative Code Env-Wt 300, 400, 600 - Criteria And Conditions For Fill And Dredging In Wetlands Action-Specific ARARs • • • • RCRA RCRA RCRA RCRA - Releases From solid Waste Management Units Closure and Post Closure Preparedness and Prevention Contingency Plan and Emergency Procedures • • • • • • • • • • • • RCRA - Requirements for Tank Systems RCRA - Use and Management of Containers RCRA - Temporary Storage of Hazardous Soils RCRA - Requirements for Equipment Leaks At TSDFs RCRA - Design and Operating Requirements for Waste Piles and Landfills CWA - Pretreatment Standards for POTW Discharge New Hampshire Rules for Identification and Listing of Hazardous Waste New Hampshire Standards for Owners and Operators of Hazardous Waste Facilities New Hampshire Pretreatment Standards New Hampshire Terrain Alteration Requirements New Hampshire Ambient Air Limits for Toxic Air Pollutants New Hampshire Fugitive Dust Control Requirements Policies, Guidelines and Criteria To Be Considered In addition, the following policies, criteria, and guidelines (to be considered, or "TBCs") will be considered during the implementation of the remedial action: • EPA Risk Reference Doses • NOAA Technical Memorandum NOS OMA 52 • EPA Carcinogen Assessment Group Potency Factors • Federal Groundwater Protection Strategy • RCRA - Proposed Air Pollutant Emission Standards For Owners and Operators of TSDFs • CAA - Proposed Performance Standards for NMOC Emissions at New and Existing Municipal Solid Waste Landfill • CERCLA Off-Site Disposal Policy Table 20 included in Appendix A provides a complete listing of the ARARs and TBCs for Alternative SC-2A, including regulatory citations, requirement synopsis, actions to be taken to attain the requirements, and determinations as to whether the requirements represent ARARs or TBCs. The following narrative presents a summary of some of the key ARARs and their applicability to the selected remedy. Federal and State Water Quality Criteria The preferred option for discharge of treated groundwater collected during construction dewatering is to the base wastewater treatment plant. Under this option, discharge limits would be based on factors regulated by the POTW's NPDES permit, pretreatment regulations, and water pollution controllaws, which are discussed under action-specific ARARs. Because final discharge from the POTW would be to Great Bay, federal and New Hampshire Water Quality Criteria are ultimately applicable to this discharge option. Pretreatment standards are being developed with the City of Portsmouth who is the current operator of the plant. Both the Pretreatment Standards and CWA NPDES will be attained upon successful establishment of pretreatment standards for discharge from the on-site mobile groundwater treatment system. Federal and State Air Quality Regulations The technologies proposed in the selected remedy will not create any new sources of air emissions. Therefore, many federal and state regulations governing air quality do not apply to the selected remedy. The only air quality standards that are applicable are particulate standards promulgated under the Clean Air Act and New Hampshire Ambient Air Quality Standards. The particulate standard would apply to remedial construction activities associated with cap installation. These standards would be attained through monitoring and, if necessary, use of dust suppression techniques or engineering controls. Potential emissions from the closed landfill would be in compliance with Performance Standards for Nonmethane Organic Compounds for new and existing municipal landfills as specified under the Clean Air Act. State Location-Specific Regulations All of the location-specific ARARs that apply to the selected remedy are based on the close proximity of the site to Flagstone Brook and Railway Ditch. New Hampshire Environmental Regulations provides that removal of soils or other activities conducted adjacent to streams must not cause unreasonable soil erosion, cause unreasonable harm to significant wildlife habitats, unreasonably interfere with natural water flow, lower water quality, or unreasonably cause or increase flooding. Additionally, NHDES regulations provides standards for erosion control and soil excavation. Implementation of the selected remedy would not impact the drainage or natural flow of Flagstone Brook and Railway Ditch. Erosion control measures will be employed during construction to minimize soil/sediment from entering Flagstone Brook or Railway Ditch. Federal and State Hazardous Waste Regulations The applicability of RCRA and New Hampshire Hazardous Waste Regulations depends on whether the wastes are RCRA hazardous wastes as defined under these regulations. To date, there is no information available (i.e., manifests) to indicate that RCRA-regulated materials were disposed of at LF-5. However, because toxic constituents are present in the waste materials and groundwater at LF-5 many portions of the federal and state hazardous waste regulations are relevant and appropriate to the selected remedy. RCRA General Facility Standards, Preparedness and Prevention, and Contingency Plan and Emergency Procedures will be attained during operation of the mobile groundwater treatment system. The facility will be designed, maintained, constructed, and operated to minimize the possibility of an unplanned release that could threaten human health or the environment. During remedial construction safety and communication equipment will be installed at the site, and local authorities will be familiarized with site operations. Contingency plans will be developed and implemented during site work and treatment system operation. A program will be developed for handling storage, and record keeping in accordance with New Hampshire Hazardous Management Rules. A post closure monitoring program will be developed for LF-5 in accordance with RCRA Releases from Solid Waste Management Units and Closure and Post-Closure regulations. During treatment of contaminated groundwater collected during construction dewatering, sludges containing some toxic constituents will be produced. A component of groundwater treatment includes laboratory analysis of this sludge, including Toxicity Characteristic Leachate Procedure (TCLP) testing. If the sludge fails TCLP testing, this material will be considered hazardous. As a characteristic hazardous waste, RCRA regulations including Land Disposal Restrictions, will apply and the sludge will be treated and disposed of in a RCRA Subtitle C facility. Because toxic constituents are present on site, OSHA regulations protecting worker health hazardous waste sites are applicable to the implementation and long-term operation of the remedy. Site workers will have completed training requirements and will have appropriate and safety equipment on site. Contractors and subcontractors working on site will follow safety procedures. and safety at selected health health and Although LF-5 may take material from LF-2 and LF-4 as subgrade fill, it is not necessary for LF-5 to obtain a permit under the New Hampshire Hazardous Waste Rules or other New Hampshire regulations. Landfills 2, 4, and 5 are all part of a single National Priorities List site, Pease Air Force Base, (55 Federal Register 6154, February 21, 1990), and therefore the activities can be viewed as taking place on site. Moreover, if Landfills 2, 4, and 6 are viewed as separate facilities, CERCLA 104(d)(4) allows the lead agency broad discretion to treat non-contiguous facilities as one site for the purpose of taking response action, including where the sites, as here, are related based on geography or on the basis of waste treatment compatibility. See 55 Federal Register 8690 (March 8, 1990). C. The Selected Remedial Action is Cost-Effective In the judgment of the Air Force, the selected remedy is cost effective (i.e., the remedy affords overall effectiveness proportional to its costs). Once alternatives that were protective of human health and the environment and that either attain, or, as appropriate, waive ARARs were identified, the overall effectiveness of each alternative was evaluated by assessing the relevant three criteria-long-term effectiveness and permanence; reduction in TMV through treatment; and short-term effectiveness. The relationship of the overall effectiveness of these remedial alternatives was determined to be proportional to their costs. A summary of the costs associated with each of the source control remedies follows. presented in net present worth costs. All costs are Four of the alternatives are protective and attain ARARs: SC-2A, SC-3A, SC-4D, and SC-5A. Comparing these alternatives, the selected alternative, SC-2A, combines the most cost-effective remedial alternative components that were evaluated. The remedy provides a degree of protectiveness proportional to its costs. Alternative SC-5A is 40% more costly than Alternative SC2A, without providing a commensurate increase in protectiveness. While Alternative SC-4D considers the EPA preference for a treatment component via thermal treatment of hot spot soils, it is 20% more costly and does not provide an increased degree of protectiveness over Alternative SC-2A, since Alternative SC-2A prevents receptor access to and migration of hot spot contaminants. Alternative SC-3A, like Alternative SC-2A involves the construction of a cap over the landfill and landfill debris dewatering. However, Alternative SC-3A would provide for reduction of contaminant migration via artificial lowering of the water table to a level below in-site debris. In contrast, Alternative SC-2A would reduce migration of contaminants by placing landfill debris on top of the landfill at least 2 feet above the water table. Each would achieve the same degree of protectiveness, but Alternative SC-2A would do so at a slightly lower cost. Additionally, while the costs for Alternative SC-2A and Alternative SC-3A are very nearly the same, it must be remembered that all present worth costs were calculated assuming a 30-year project life. In reality, the pump and-treat component of SC-3A would have to continue indefinitely to provide long-term effectiveness. In addition, continuous pumping of the aquifer beneath LF-5 could adversely affect wetlands in the area by removing an important source of recharge. Additionally, contaminant migration mitigation is addressed in the Zone 1 Draft FS, which was completed in August 1993. Alternative SC-1 (no-action) does not meet all ARARs and is not sufficiently protective of human health and the environment. A summary of costs for key elements of the selected source control remedy follows. present worth. Component of Remedy Landfill excavation/consolidation Sediment excavation/consolidation Groundwater dewatering system Mobile groundwater treatment system Composite barrier cap installation O&M Miscellaneous TOTAL (rounded) All costs are net Present Worth ($) $4,334,050 539,175 651,000 332,610 6,215,160 5,290,669 6,629,721 $23,992,000 O&M includes groundwater, surface water, sediment and air monitoring, 5-year SARA review, surveying and subsidence monitoring, replacement costs for fencing and monitor wells, and access restrictions. Miscellaneous includes mobilization and health and safety costs, contingency costs, and additions and modifications to monitoring systems. D. The Selected Remedy Utilizes Permanent Solutions and Alternative Treatment or Resource Recovery Technologies to the Maximum Extent Practicable Once those alternatives that attain or, as appropriate, waive ARARs and that are protective of human health and the environment were identified, the Air Force identified which alternative utilizes permanent solutions and alternative treatment technologies or resource recovery technologies to the maximum extent practicable. This determination was made by deciding which one of the identified alternatives provides the best balance of trade-offs among alternatives in terms of: 1) long-term effectiveness and permanence; 2) reduction of toxicity, mobility, or volume through treatment; 3) short-term effectiveness; 4) implementability; and 5) cost. The balancing test emphasized long-term effectiveness and permanence and the reduction of TMV through treatment; and considered the preference for treatment as a principal element, the bias against off-site land disposal of untreated waste, and community and state acceptance. The selected remedy provides the best balance of trade-offs among the alternatives. Alternatives SC-3A, SC-4D, and SC-5A all out rank Alternative SC-2A based on emphasis on reduction of TMV through treatment. In addition, both Alternatives SC-3A and SC-4D place greater emphasis on the preference for treatment as a principal element. However, the costs for Alternatives SC-4D and SC-5A exceed those for Alternative SC-2A by 20 and 40%, respectively. As described, implementation of the treatment portion of Alternative SC-3A extends the remedial action beyond the 30-year time frame allotted for costing purposes, and may adversely impact wetlands at LF-5 via dewatering of a wetland recharge area. In addition, implementation of remediation will further address the reduction of TMV and EPA preference for treatment. Alternative SC-1 contains no provision for reduction in TMV or for consideration of the statutory preference for treatment as a component of remediation. E. The Selected Remedy Does Not Satisfy the Preference for Treatment which Permanently and Significantly Reduces the Toxicity, Mobility, or Volume of the Hazardous Substances as a Principal Element The principal element of the selected source control remedy is the containment of waste in LF-5. The principal element of the Zone 1 remedial alternative is management of contaminant migration via groundwater and surface waters. Together, these elements address the primary threat at the site, namely, direct contact with contaminants in landfill soil and debris and migration of this contamination to groundwater and surface waters. Treatment is not the principal element of the selected source control alternative because treatment of landfill debris is not practical or cost-effective given the size and heterogeneity of the landfill contents. The selected source control remedy may, however, involve treatment of groundwater extracted during construction dewatering, which should remove much of the contaminants currently present in groundwater. XII. DOCUMENTATION OF SIGNIFICANT CHANGES The LF-5 Draft Final FS (F-494) was completed in August 1992. The original Proposed Plan for LF-5 was completed in January 1993. This Proposed Plan documented the U.S. Air Force's selected remedy for source control at LF-5. During the public comment period (14 January through 13 February 1993) and public hearing (27 January 1993) that followed the public expressed a preference for consolidating as many Pease landfills as possible in one area, so as to minimize the total acreage of land that would be designated as having restricted use. In addition, several other concerns were raised regarding the selected remedy, such as disposal of treated groundwater from construction dewatering in Flagstone Brook. In response to public input, the U.S Air Force completed a revised Proposed Plan for LF-5 source control, which included as a remedial component, the potential consolidation of LF-2 and LF-4 onto LF-5. This revised Proposed Plan for LF-5 was completed in July 1993 and public comment period for the Revised Proposed Plan was held from 20 July to 19 August 1993. The following paragraphs describe changes to the selected remedy and other minor changes that occurred following issuance of the original Proposed Plan for LF-5. One modification involves the potential consolidation of materials from two other Zone 1 landfills (LF-2 and LF-4) onto LF-5. The change would result in: 1) an increase in the total volume of landfill soil and debris to be consolidated (an additional 76,320 yd[3]), 2) possible changes in the final height and grading of the landfill prior to capping, 3) possible impacts to additional Zone 1 wetlands already expected to be impacted, and 4) increased short-term risks associated with soil inhalation, due to the increased time for and extent of excavation. These changes would be expected to be small in comparison with the entire scope of LF-5 remedial actions and are not expected to significantly alter the cap design criteria presented in the LF5 FS. These changes would not be expected to adversely impact the overall ranking of Alternative SC-2A as the preferred alternative. Sections VIII, IX, and X provide further detail on the potential impacts of adding LF-2 and LF-4 remediation to the scope of Alternative SC-2A. Consolidation of LF-2 and LF-4 onto LF-5 is the preferred alternative in part due to public comments on the original Proposed Plan for LF-5. These comments-expressed a desire for consolidation of as many landfills as possible in order to retain more land at Pease AFB for unrestricted development. The remedial action was also selected due to its relative ease of implementation, and due to the resulting closure of both LF-2 and LF-4 that would result. Excavation and consolidation of LF-2 and LF-4 onto LF-5 is not evaluated in an FS as is the typical practice. Instead, the Air Force's plans to implement this remedy will be outlined in the Proposed Plan and Record of Decision for Zone 1. A final decision under CERCLA will be required prior to implementation of the proposed excavation and consolidation plan for LF-2 and LF-4. A second modification involves disposal of treated groundwater from construction dewatering. Based on public comments received on the original Proposed Plan, discharge of treated groundwater extracted during construction dewatering will be to the sanitary sewer rather than Flagstone Brook. Since issuance of the revised Proposed Plan for Landfill-5, there have been no significant modifications to the LF-5 selected remedy. Public comments and comments from EPA and NHDES pertaining to the specifics of the LF2/LF-4 remedy are addressed in this ROD. XIII. STATE ROLE The NHDES reviewed the various alternatives and has indicated its support for portions of the selected remedy. The state has also reviewed the RI, RA, and FS to determine if the selected remedy is in compliance with applicable or relevant and appropriate state environmental laws and regulations. The NHDES, as a party to the FFA, concurs with the selected remedy for the Pease AFB site. A copy of the declaration of concurrence is attached as Appendix B. XIV.

Babbitt Deputy for Hazardous Materials and Waste; Deputy Assistant Secretary of the Air Force (Environment Safety and Occupational Health) Suite 5C866, Pentagon Washington, D.C. 20330-1660 RE: Site 5 Source Area Record of Decision Pease Air Force Base Superfund Site Pease Air Force Base, New Hampshire Subject: Declaration of Concurrence Dear Mr. Babbitt: The New Hampshire Department of Environmental Services (NHDES) has reviewed the September 1993 Record of Decision (ROD) regarding source control remedial actions at Site 5 - Landfill 5 at the Pease Air Force Base Superfund Site located in Newington and Portsmouth, New Hampshire. Management of contaminant migration will be addressed in the Zone 1 ROD. The source control action consists of a multi-component approach for the containment of contaminant source materials as outlined in the following: I. Excavation and consolidation of selected Railway Ditch sediments on the existing landfill. II. Excavation of soil and solid wastes in Landfills 2 and 4 and consolidation on Landfill 5. III. Excavation of soil and solid wastes predicted to be below the water table after capping and placement of excavated material on the existing landfill. Dewatering of areas requiring excavation, on-site treatment of the extracted groundwater and discharge to the local wastewater treatment plant may be necessary. Treated effluent will also be used for site dust control. IV. Regrading and capping of the landfill with a composite cap. The capwill consist of the following (from top to bottom): • A protective cover layer, comprised of a minimum of 36 inches of drain sand and 6 inches of mulched, seeded topsoil. • A drainage composite layer, composed of a single-layer high density polyethylene (HPDE) drainage net with a nonwoven needle-punch geotextile. The drainage composite layer and the underlying geomembrane will be terminated in a perimeter anchor trench fitted with a subdrain perforated plastic pipe embedded in crushed stone. • A composite barrier layer, consisting of a clay mat overlain by a 40-mil, very low density polyethylene (VLDPE) geomembrane. The clay mat will be composed of bentonite clay bonded to geomembrane or a geotextile. • A 12-inch subbase gas ventilation layer with gas vents overlain with geotextile to serve as a bedding layer for the overlying composite barrier. V. Destruction of wetlands will require the construction of appropriate wetlands, based on a functional evaluation and assessment of wetlands prior to commencement of construction activities, in non-wetland areas. VI. Placement of institutional controls. Deed restriction will be imposed to restrict future activities that could violate the integrity of the cap. VII. Conducting long-term environmental monitoring to ensure the integrity of the cap is maintained and ensure the waste material remains dry. Based upon its review, NHDES has determined the source area remedial action is consistent with, or exceeds, applicable or relevant and appropriate state standards. NHDES, as a party to the Pease Air Force Base Federal Facility Agreement and acting as agent for the State of New Hampshire, concurs with the selected remedial action. This concurrence is based upon the State's understanding that: A. NHDES will continue to participate in the Pease Air Force Base Federal Facility Agreement and in the review and approval of the Zone 1 ROD, remedial design and action documents, and the following Landfill 5 operational designs and monitoring plans: • • • The capping system; The gas management system and post-closure landfill gas monitoring plan; The landfill settlement monitoring system and monitoring plan; - The stormwater management (drainage) system as typically incorporated into landfill closure plans through issuance of a Significant Alteration-of-Terrain Permit; - The groundwater and surface water monitoring system; -Long-term operation and maintenance plan; and - Post closure access control systems. B. The purpose of the NHDES' closure standards is to ensure, "...all facilities shall be closed in a manner that does not endanger public health or adversely affect the environment and which minimizes the potential for accidents that could lead to personal injury or property damage" (Env-Wm 312.01). NHDES' Landfill Capping System Standards (Env-Wm 2505.10) require landfill capping systems be designed to, "...reduce leachate generation by limiting to the extent practicable precipitation and surface water infiltration of the waste, through placement of low-permeability cover materials over the landfilled areas". The low permeability barrier shall, "minimize the infiltration of water into underlying wastes so as to limit continued leachate production and the associated adverse impacts to the quality of groundwater and surface waters; and consist of a geomembrane with a minimum thickness of 40 mils or a low permeability soil, or admixture". NHDES' solid waste closure requirements are primarily performance based and as such, provide a degree of flexibility in allowing capping systems which will provide functionally equivalent protection of human health and the environment. The composite cap, specified by the USEPA, is a RCRA Subtitle C (hazardous waste) type closure cap which exceeds the specifications used at most municipal solid waste landfills (RCRA Subtitle D) in New Hampshire. Although RCRA C type wastes were found within a portion of the landfill during Stage 2 investigations, a drum removal action was completed in January of 1990. Subsequent test pit excavations indicate Landfill 5 is primarily a solid waste landfill which contains some hazardous waste constituents typically found in a municipal solid waste landfill. The environmental impact from Landfill 5 wastes is similar to the impact associated with a typical municipal solid waste landfill and would otherwise be closed under the NHDES' solid waste regulations. C. The excavation and subsequent consolidation of soil and solid waste, in order to remove waste from contact with groundwater, is an accepted source control action. The discharge of treated groundwater, extracted during excavation dewatering activities, from a mobile on-site treatment unit to the base sewer will require the development of discharge limits in coordination with the City of Portsmouth (operator of the base wastewater treatment plant) in order to ensure compliance with the existing National Pollution Discharge Elimination System permit, pretreatment regulations and water pollution control laws. D. Any wetlands adversely impacted by the source control action will be restored, subject to the provisions of RSA 482-A and Env-Wt 100 through Wt 800. E. The Pease Development Authority (PDA) plans to construct an access road to the North Ramp, adjacent to Landfill 5. The Air Force and the PDA will coordinate the consolidation and the design and construction of the landfill cap and access road to ensure the integrity of the cap and capping systems. F. Long-term monitoring will be necessary in order to determine the effectiveness of the source control action. Long-term monitoring of the management of contaminants in groundwater will be addressed in the Zone 1 ROD. The frequency and location of water quality monitoring is determined on a site specific basis and is typically required tri-annually until a baseline condition is established. A comprehensive, detailed review will be conducted by the Air Force, the USEPA and the NHDES within five years after remediation to ensure the remedy provided adequate protection of human health and the environment.

Land use in the area is predominantly commercial and residential, with wetlands and woodlands areas located onsite. Current land use at the site is institutional, agricultural, abandoned land, and unoccupied residential. Three drainage ditches, the Upper Newfields Ditch, the Southern Ditch, and the Test Cell Ditch, which receive runoff from the site, intersect the water table and are discharge points for shallow ground water. The site has been divided into several zones. Zone 3 includes Buildings 244, 113, 229, 222 (Jet Engine Test Cell), 228, 119, 120, and 227. The Jet Engine Test Cell (JETC), known as Site 34, consists of Building 222, the JP-4 Tank Area, the Fuel Oil Tank/Waste Fuel Separator Area, the manhole area, the holding tanks area, and the aircraft parking apron. From 1970 until its closure in 1991, the Air Force used the JETC to test jet engines through complete power ranges using a process during which water was injected into the exhaust stack to reduce exhaust temperature, hydrocarbon emissions, and noise. Runoff from the tests and washdown activities was routed through an oil/water separator and then discharged directly into the Test Cell Ditch. A number of investigations conducted as part of the Department of Defense's Installation Restoration Program (IRP) in 1983, identified records that documented that releases of chemical waste from the JETC to surrounding soil had occurred from the oil/water separator. In 1989, modifications were made to eliminate wastewater discharged to the storm drain by collecting the water in two 3,000-gallon underground storage tanks (USTs). A pilot ground water remediation system, consisting of two bedrock recovery wells and a ground water treatment plant (GWTP), was constructed at Site 34 during 1990 and 1991. Ground water from the recovery wells is treated to remove iron, manganese, and dissolved organic contaminants, and then discharged onsite to the base sanitary sewer system. In addition to these actions under the IRP, the JETC drain system was reconfigured, and holding tanks were installed to eliminate discharges of effluent from the exhaust stack area to the Test Cell Ditch; floor drains in the Test Cell Bay were plugged to prevent contaminant discharges to the Test Cell Ditch; a heating oil tank suspected of leaking was abandoned; a buried JP-4 tank was removed; and anaboveground JP-4 tank equipped with appropriate spill containment was installed. This ROD addresses sources of contamination, ground water treatment, and debris removal at the JETC, as OU2. Future RODs will address ground water contamination in Zone 3 as well as sediment in site drainage ditches and wetlands, if necessary. The primary contaminants of concern affecting the soil, debris, and ground water are VOCs, including benzene, TCE, toluene, and xylenes; other organics, including PAHs; and metals, including arsenic, chromium, and lead. SELECTED REMEDIAL ACTION: The selected remedial action for this site includes excavating approximately 11,900 yd[3] of soil from the JP-4 Tank Area, the Fuel Oil Tank/Waste Fuel Separator Area, the manhole area, and the holding tank area; temporarily storing and dewatering 5,350 yd[3] of contaminated excavated soil onsite; treating the excavated soil offsite using incineration, thermal desorption, or asphalt batching, or disposing of it at a RCRA or Subtitle D landfill; disposing of excavated contaminated material at a location to be determined during the RD phase; backfilling approximately 6,550 yd[3] of soil not requiring treatment that was excavated to access contaminated soil; replacing the excavated areas with clean fill; treating ground water extracted as part of the excavation and/or dewatering process using the existing pilot GWTP, which utilizes potassium permanganate injection in conjunction with flow equalization, greensand filtration, and activated carbon adsorption, with onsite discharge to surface water; removing remaining onsite USTs and associated piping from the manhole and Test Cell Ditch; and conducting environmental monitoring. The estimated present worth cost for this remedial action is $1,169,298, which includes an estimated total O&M cost of $111,351. PERFORMANCE STANDARDS OR GOALS: Cleanup goals are based on State ARARs and SDWA MCLs. Chemicalspecific soil cleanup goals include 1 mg/kg for benzene, ethylbenzene, toluene, and total xylenes. Chemical-specific ground water cleanup goals include arsenic 50 ug/l; benzene 5 ug/l; lead 15 ug/l; and TCE 5 ug/l in the excavation dewatering process, and benzene 0.005 mg/l; toluene 1 mg/l; and total xylenes 10 mg/l for application of the leaching model. INSTITUTIONAL CONTROLS: Not applicable. Remedy: This action addresses the principal threat posed by Site 34 by preventing endangerment of public health, welfare, or the environment by implementation of this ROD through remediation of the soil; thereby minimizing the leaching potential of soil contaminants to groundwater. The selected remedy includes the excavation of contaminated soils and drainage piping associated with Site 34. Also included is groundwater extraction and treatment for excavation dewatering purposes. The treatment and/or disposal of soils removed from the site will include one of the following; thermal desorption elsewhere on the base, asphalt batching of the soils at an off-base vendor location, or disposal at a Subtitle D Landfill or RCRA facility, as deemed necessary at the time of remediation. Groundwater will be extracted during soil removal activities and extraction will continue until backfilling with clean fill is completed. Contaminated groundwater will be extracted via a well and sump extraction system and will be treated at the existing Pilot Groundwater Treatment Plant (GWTP) at Site 34. The groundwater treatment technology to be used includes greensand filtration followed by activated carbon adsorption. Additional storage capacity would be required during remedial activities as the rate of extraction will likely be greater than the existing 20-25 gpm capacity of the GWTP. The preferred discharge method for the treated water is the base wastewater treatment facility as the pilot GWTP already discharges to the basesewer system. However, coordination with the City of Portsmouth as the current operator, would be required prior to any additional discharges. Treated water must meet the pretreatment standards established by the operator of the base wastewater treatment facility. Ultimate discharge will be to the Piscataqua River under a National Pollutant Discharge Elimination System (NPDES) permit. Text: Full-text ROD document follows on next page.

This decision document was developed in accordance with the Comprehensive Environmental Response, Compensation, and Liability Act as amended by the Superfund Amendments and Reauthorization Act of 1986, and, to the extent practicable, the National Contingency Plan. Through this document, the Air Force plans to remedy the threat to human health, welfare, or the environment posed by contaminated soil associated with Site 34. This decision is based on the Administrative Record for the site. The Administrative Record for this site is located at the Information Repository in Building 43 at Pease International Tradeport (Formerly Pease AFB, New Hampshire). The Administrative Record Index as applies to Site 34 may be found in Appendix E. The State of New Hampshire Department of Environmental Services (NHDES) and the U.S. Environmental Protection Agency (USEPA) concur with the selected remedy. ASSESSMENT OF THE SITE Actual or threatened releases of hazardous substances from Site 34 soils, if not addressed by implementing the response action selected in the Record of Decision (ROD), may present an imminent and substantial endangerment to public health, welfare, or the environment. DESCRIPTION OF THE SELECTED REMEDY This action addresses the principal threat posed by Site 34 by preventing endangerment of public health, welfare, or the environment by implementation of this ROD through remediation of the soil; thereby minimizing the leaching potential of soil contaminants to groundwater. The selected remedy includes the excavation of contaminated soils and drainage piping associated with Site 34. Also included is groundwater extraction and treatment for excavation dewatering purposes. The treatment and/or disposal of soils removed from the site will include one of the following; thermal desorption elsewhere on the base, asphalt batching of ?? soils at an off-base vendor location, or disposal at a Subtitle D Landfill or RCRA facility, as deemed necessary at the time of remediation. Groundwater will be extracted during soil removal activities and extraction will continue until backfilling with clean fill is completed. Contaminated groundwater will be extracted via a well and sump extraction system and will be treated at the existing Pilot Groundwater Treatment Plant (GWTP) at Site 34. The groundwater treatment technology to be used includes green sand filtration followed by activated carbon adsorption. Additional storage capacity would be required during remedial activities as the rate of extraction will likely be greater than the existing 20-25 gpm capacity of the GWTP. The preferred discharge method for the treated water is the base wastewater treatment facility as the pilot GWTP already discharges to the base sewer system. However, coordination with the City of Portsmouth as the current operator, would be required prior to any additional discharges. Treated water must meet the pretreatment standards established by the operator of the base wastewater treatment facility. Ultimate discharge will be to the Piscataqua River under a National Pollutant Discharge Elimination System (NPDES) permit. STATUTORY DETERMINATIONS The selected remedy is protective of human health and the environment, complies with federal and state requirements, that are legally applicable or relevant and appropriate to the remedial action, and is cost-effective. This remedy uses permanent solutions and alternative treatment technologies to the maximum extent practicable. The method of disposal or treatment of the excavated soils will be determined during the remedial design phase. The determination will reflect the requirement of CERCLA 120(b)(1) that states "Remedial actions in which treatment which permanently and significantly reduces the volume, toxicity or mobility hazardous substances, pollutants or contaminants is a principal element, are to be preferred over remedial alternatives not involving such treatment". A review will be conducted by the Air Force, the USEPA, and the NHDES within five years after remediation to ensure that the remedy provided adequateprotection of human health and the environment. The foregoing represents the selection of a remedial action by the United States Air Force and the U.S. Environmental Protection Agency, Region I, with concurrence of the New Hampshire Department of Environmental Services. Concur and Recommended for immediate implementation: RECORD OF DECISION SUMMARY I. SITE NAME, LOCATION, AND DESCRIPTION Pease AFB is a National Priorities List site consisting of numerous areas of contamination. This ROD addresses sources of contamination at the Jet Engine Test Cell (JETC) (also designated as Building 222 or Site 34). The JETC site occupies approximately 3 acres in the central portion of the former base. The JETC was used by the Air Force to test the performance of jet engines through complete power ranges. The former base is located in the Town of Newington and the City of Portsmouth, both of which are in Rockingham County, New Hampshire. As shown in Figure 1, Pease AFB is located on a peninsula in southeastern New Hampshire. The peninsula is bounded on the west and southwest by Great Bay, on the northwest by Little Bay, and on the north and northeast by the Piscataqua River. The City of Portsmouth is located southeast of the base. Pease AFB occupies 4300 acres and is located approximately in the center of the peninsula. The current land uses at Pease AFB are institutional, woodland, agricultural, abandoned land, and residential (currently unoccupied). Commercial and residential areas are located off base along Spaulding Turnpike, approximately 1,000 feet northeast of the Pease AFB eastern boundary, and Interstate I-95, which is located along the southeastern base boundary. The largest commercial complex is a shopping mall located on the eastern side of Spaulding Turnpike. Figure 2 is the general land use map for the Industrial Shop/Parking Apron (IS/PA) area of Pease AFB, and shows the location of the JETC within the IS/PA. Prior to the construction of Pease AFB, the area at what is currently the JETC was primarily woodlands. The wetlands currently located on-site were not present before construction of the JETC facility, based on review of historic aerial photos. The development of the wetlands is thought to be due to the grading and paving activities associated with the aircraft parking apron and Dover Avenue. The primary sources of historic and current land use information for the JETC area include the USGS topographic quadrangle maps (Portsmouth Quadrangle, photorevised, 1981), aerial photographs (1958 to 1986), and a series of maps prepared for the New Hampshire Coastal Zone Study (1975). Facilities adjacent to the JETC include an aircraft hangar (Building 227) to the north-northwest, the former Munitions Maintenance Squadron (Building 113), the former Jet Engine Maintenance Building (119) to the northeast, and the aircraft parking apron to the west. Building 227 is currently leased from the Pease Development Authority (PDA) by Business Express (a Delta Commuter Airline) for aircraft storage and maintenance. Buildings 113 and 119 were given the designation Site 32/36, and are also being investigated under the IRP. Building 113 is currently leased to the U.S. Navy, and Building 119 is currently used by the PDA for maintenance activities. The aircraft parking apron is used for aircraft parking, refueling, and minor aircraft maintenance. Surface drainageways at Pease AFB flow radially away from the center of the peninsula, toward Great Bay to the west, Little Bay to the northwest and north, and the Piscataqua River to the east. Great Bay, Little Bay, and the Piscataqua River are all tidally influenced and, consequently, are subjected to semidiurnal variation in water levels. The peninsula has relatively low relief, with the runway and aircraft parking apron located on the topographically highest portion of the peninsula. The runway and aircraft parking apron are on a surface drainage divide, with runoff to the northeast of the divide ultimately discharging to the Piscataqua River, and runoff southwest of the divide ultimately discharging to Great Bay. Locally, the surface hydrology of the JETC may be divided into four hydrologic zones: the paved and storm-drained aircraft parking apron, the relatively well-drained areas immediately adjacent to the aircraft parking apron, the poorly drained wetlands, and three drainage ditches, of which the Test Cell Ditch is one. The relationship of the 100-year floodplain to the JETC site is not known since floodplain location maps are not available for Pease AFB. Surface relief in the area is minimal. The change in elevation from a given low point to the adjacent high is only 10 feet, and slopes are gentle. The highest elevations, approximately 60 feet above mean sea level (ft MSL), are on the aircraft parking apron. The aircraft parking apron is constructed of portland cement concrete, and the joints between the concrete slabs have been sealed. The aircraft parking apron is, therefore, relatively impermeable. The surface of the aircraft parking apron is graded such that most runoff is directed storm drain catch basins for eventual discharge to McIntyre Brook. McIntyre Brook flows from the southwestern edge of the runway toward Great Bay. Snowfall on the aircraft parking apron is cleared and banked on adjacent areas, including the area around Building 222. These snowbanks contribute meltwater to the site. Building 222 is on a relative topographic high, and there is a localized drainage divide. Runoff from Building 222 and areas southwest of the divide flows toward the Test Cell Ditch. Runoff from the Building 222 parking lot and areas northwest of the divide flows toward a northern ditch (Upper Newfields Ditch), which runs parallel with, and approximately 400 feet northwest of, the Test Cell Ditch. A third drainage ditch, the Southern ditch, which begins approximately 300 feet southeast of the Test Cell Ditch, joins the Test Cell Ditch at Dover Avenue. The Test Cell Ditch receives most of the surface runoff from the site (excluding the storm-drained areas of the aircraft parking apron). The Test Cell Ditch and the Southern Ditch discharge to the storm drain system under Dover Avenue for eventual discharge to Grafton Ditch. Flow in Upper Newfields Ditch flows under Dover Avenue near Building 119. All three ditches intersect the water table and, hence, are discharge points for shallow groundwater. This is indicated by dry period flows in the ditches. During prolonged dry periods, the ditches may be dry for most of their lengths as the water table drops. Pumping the GWTP recovery wells affects flow in the Test Cell Ditch because the water table is lowered by pumping. In the past, the Test Cell Ditch received cooling and wash down waters discharged from the JETC. The JETC is no longer in use; however, prior to its being taken out of service, discharges of these waters were rerouted to two holding tanks that are periodically emptied for off-site disposal. Much of the runoff from other areas of the site either pools or infiltrates in the wetlands, and does not reach the drainage ditches as overland flow. There is little runoff from the wetlands; they are primarily an area of infiltration, evapotranspiration, and groundwater recharge. The wetlands are discussed in greater detail in Subsection 2.4.7 of the Draft Final Site 34 RI Report (F-499). II. A. SITE HISTORY AND ENFORCEMENT ACTIVITIES Site Use and Response History The JETC was constructed in the late 1960s and has been in operation from 1970 until closure of the facility in 1991. The JETC was used to test jet engines through complete power ranges. During an engine test, water was injected into the exhaust stack to reduce exhaust temperature, hydrocarbon emissions, and noise. A single test could use 3,000 gallons or more of water. Additional water and wastes (i.e., fuel, hydraulic fluid, and cleaning solvents) were generated during washdown activities in the test bay area. Liquids from the facility were routed through an oil/water separator and then discharged to the Test Cell Ditch. In 1989, modifications were made to eliminate wastewater discharged to the storm drain by collecting the water in two 3,000gallon underground storage tanks (USTs). A UST for jet fuel (JP-4) was located on-site. A more detailed description of site history is presented in Sections 1 and 3 of the Draft Final Site 34 RI Report (F-499). The JETC was first identified as an area of possible environmental concern in 1983 during the Installation Restoration Program (IRP), Phase I Problem Identification/Records Search (F-75). The purpose of that study was to identify and evaluate suspected problems associated with past practices at Pease AFB. Records show that releases from the JETC to surrounding soils occurred from the oil/water separator. Product was visually observed in an excavated septic tank trench near Building 222 during Phase I. Following the Phase I study, Phase II Site Investigations, Stages 1 through 3 were initiated under the IRP. The Phase II, Stage 1 (September 1984 to January 1986) investigation consisted of completing two borings to the southeast of Building 222. One soil sample was collected from each boring for chemical analysis. The results of this investigation are reported in the Phase II, Stage 1 Confirmation/Quantification Final Report (F-44). The Phase II, Stage 2 (October 1987) Site Investigation effort focused on further characterizing the extent of soil contamination and the effect of site activities on groundwater, surface water, and sediment. Stage 2 activities included a soil-gas survey; six soil borings; installation of one bedrock well; and soil, groundwater, surface water, and sediment sampling for laboratory analyses. The results of the Stage 2 investigation are reported in the Stage 2 Draft Final Report (F-455) and Interim Technical Report (ITR) No. 2 (F-453). Based on the data generated during Stage 2, additional field investigations and Interim Remedial Measures (IRMs) were implemented as part of Stage 3. The 1990 Stage 3 field investigations included installing two bedrock wells, test pit investigations, and wetlands delineations. IRMs consisted of soil and sediment removal along the Test Cell Ditch and the design and installation of a pilot groundwater treatment plant (GWTP). A pilot groundwater remediation system (GRS) was constructed as an IRM at Site 34 during 1990 to 1991. The goals of the GRS were to limit the migration of contaminants in groundwater, to remove contaminant mass from the subsurface, and to evaluate potential treatment technologies to be used in the final site remediation. The GRS consists of a groundwater recovery system and a GWTP. The groundwater recovery system consists of two bedrock recovery wells located at the southeastern end of the source area in the dissolved contaminant plume. The average combined yield from the recovery wells is approximately 21 gallons per minute (gpm). Groundwater from the recovery wells is treated to remove iron, manganese, and dissolved organic contaminants. Treated groundwater is discharged to the base sanitary sewer system. Unit processes used at the GWTP are flow equalization, greens and filtration, and activated carbon adsorption. During the first 17 months of operation, from March 1991 through July 1992, the GRS recovered and treated approximately 9.5 million gallons of groundwater. The effluent from the GWTP consistently meets drinking water standards, the requirements agreed on by NHDES and the Air Force for discharge to the base sanitary sewer system. The plant has not presented any major operational difficulties. The GRS has had more than adequate success in meeting its objectives: the groundwater recovery system has shown to be effective in capturing both overburden and bedrock water-bearing unit contaminants, and the GWTP unit processes have been effective in removing organic and inorganic constituents. Based on past operations, only minor modifications are recommended for continued operation of the Site 34 GRS during the interim period until final remedial activities are implemented. Table 1 in Appendix A summarizes the Stage 2 and 3 field investigation activities. Based on the data collected from these IRP investigations, a Site Characterization Summary (SCS) (F-482) was prepared for the JETC. The SCS included a working conceptual model and presented data required to complete a Baseline Risk Assessment (BRA) and Feasibility Study (FS). The data required to complete a BRA and FS were collected during the 1991 Stage 3 field investigation. The 1991 field investigations included installing 13 bedrock and 5 overburden wells and 19 piezometers; completing soil borings; and sampling and analysis of groundwater, soil, sediment, and surface water. A surface geophysical survey was also performed to provide information on bedrock topography and potential fractures in the JETC area. In addition to these activities, several other actions have been taken to reduce the potential for environmental impacts resulting from JETC operations. These actions and their objectives include: • Reconfiguration of the JETC drain system and installation of holding tanks to eliminate discharges of effluent from the exhaust stack area to the Test Cell Ditch. • Plugging of floor drains in the Test Cell Bay to prevent contaminant discharges to the Test Cell Ditch. Fluid generated in the bay are collected with absorbent material and containerized for proper disposal. • In-place abandonment of a heating oil tank suspected of leaking. • Removal of the buried JP-4 tank and installation of an aboveground JP-4 tank equipped with appropriate spill containment. B. Enforcement History In 1976, the Department of Defense (DOD) devised a comprehensive IRP to assess and control migration of environmental contamination that may have resulted from past operations and disposal practices at DOD facilities. In response to the Resource Conservation and Recovery Act of 1976 (RCRA) and in anticipation of CERCLA, DOD issued a Defense Environmental Quality Program Policy Memorandum, dated June 1980 (DEQPPM 80-6), requiring identification of past hazardous waste disposal sites on DOD agency installations. The program was revised by DEQPPM 81-5 (11 December 1981), which reissued and amplified all previous directives and memoranda on the IRP. Pease AFB was proposed to be added to the National Priorities List (NPL) in 1989 and was listed on the NPL in 1990. On 24 April 1991, the Air Force, U.S. Environmental Protection Agency (EPA), and New Hampshire Department of Environmental Services (NHDES) signed a Federal Facilities Agreement (FFA) establishing the protocol and timetable for conducting the Remedial Investigation/Feasibility Study (RI/FS) process at Pease AFB. As part of this timetable, the Air Force, in an effort to streamline activities, designed a basewide strategy plan for conducting an RI/FS. This strategy plan grouped the numerous sites into seven zones or operable units based on geographic location, potential receptors, and potential future uses. RI/FS report will be prepared for each zone. However, ?? to inclusion of Pease AFB on the NPL, ?? sites (including the JETC) were on an ?? RI/FS approach because of the potential threat they posed to human health and the environment. The Air Force, EPA, and NHDES agreed that the source area RI/FS reports, and the remedial actions at these five sites, would continue on an accelerated schedule toward source area cleanup. III. COMMUNITY PARTICIPATION Throughout the site's recent history, there has been community concern and involvement. EPA, NHDES, and the Air Force have kept the community and other interested parties apprised of site activities through informational meetings, fact sheets, press releases, and public meetings. In January 1991, the Air Force released a community relations plan that outlined a program to address community concerns and keep citizens informed and involved during remedial activities. This plan is currently being updated and is scheduled for completion by summer 1993. Numerous fact sheets have been released by the Air Force throughout the IRP at Pease AFB. These fact sheets are intended to keep the public and other concerned parties apprised of developments and milestones in the Pease AFB IRP. The fact sheets released to date that concern the JETC are summarized as follows: In addition to the fact sheets, a number of public meetings have been held concerning the remediation of Site 34. On 14 November 1991, an IRP update public meeting was held, and on 12 January 1993, an IRP public workshop and meeting were conducted to provide the public with information on the status of the IRP at Pease AFB. On 30 March 1993, the Air Force conducted a public hearing and information session for the JETC (Site 34) Proposed Plan, during which oral comments on the Proposed Plan were received. A transcript of oral comments received during its meeting and the Air Force's response to comments are included in the attached responsiveness summary (see Appendix D). A full transcript is available in the Administrative Record file at Pease AFB. In addition, a public comment period for the Proposed Plan was conducted between 14 March and 14 April 1993. Responses to written comments received during this period are also included in Appendix D. A complete Information Repository containing documents relating to the Pease AFB IRP is maintained at Pease AFB in Building 43. An Administrative Record containing correspondence pertaining to the Pease AFB IRP is also located in Building 43 at Pease AFB. An index of the Administrative Record is maintained at EPA Region I Headquarters in Boston, Massachusetts. IV. SCOPE AND ROLE OF OPERABLE UNIT OR RESPONSE ACTION The JETC (Site 34) is one of several contaminant sources within Zone 3. Zone 3 is a grouping of IRP sites and UST sites within the IS/PA area and is shown in Figure 1. The remedy presented in this Record of Decision (ROD) provides for source control at the JETC. Remediation at a Superfund site typically involves activities to remove or isolate contaminant source materials in conjunction with activities that mitigate migration of contamination through groundwater and/or surface water pathways. This ROD addresses only source control measures at the JETC. Management of contamination in groundwater for Zone 3 (operable unit 3) will be addressed in separate zonewide documents, including a separate Zone 3 ROD. Source material at the JETC have been identified as source are soil and associated USTs. Although sediments in site drainage ditches and wetlands areas may represent an additional source, they are not addressed in this document, but will be addressed as part of the Zone 3 remedial decision process. Groundwater and surface water are not considered source materials; however, treatment goals were generated for these media, as they may be affected by source control activities. The selected source control remedy was developed to reduce migration of contaminants from the source area soils to groundwater. In summary, the remedy provides: • Excavation of contaminated soil from the JP-4 Tank Area, the Fuel Oil Tank/Waste Fuel Separator Area, the manhole area and holding tanks area, and transport to an approved off-site treatment/disposal facility. • Dewatering of the site during soil excavation and treatment of the extracted groundwater at the existing on-site treatment facility, with subsequent discharge to the base sanitary sewer. • Backfilling of the excavation with excavated soil not requiring treatment or clean fill. • Environmental monitoring during remedial operations. • Removal of USTs and drain piping from the manhole to the Test Cell Ditch. The remedial action will address the objectives discussed in the following paragraphs. The results of the BRA for Site 34 soils indicated that no significant adverse health effects on human receptors are expected. This includes exposure resulting from incidental ingestion of, or dermal contact with, contaminated soil. The results of the ecological risk assessment indicated that no significant adverse effects on ecological receptors resulting from site-related contamination are expected. However, the potential may exist for contaminants to leach from source area soils into groundwater, resulting in human ingestion of, or direct contact with, contaminated groundwater that may present a health risk. In consideration of the aforementioned conditions, the remedial response objective for source control actions at the JETC is to minimize the leaching of contaminants from the source area soil into groundwater, thereby reducing the potential for the public to ingest or directly contact contaminated groundwater that may present a health risk. The remedy at the JETC is for contaminant source control only. The intention for this remedy is to limit contaminant leaching from soils to groundwater. Owing to the complexity of groundwater flow in the vicinity of the JETC and the priority of other sites and groundwater contaminant plumes, groundwater issues will be better evaluated on a zonewide or operable unit basis, rather than a site-specific basis. This site was targeted for source control because it was considered an area of high contamination and remedial activities for source control could be started prior to completion of the full groundwater evaluation. V. SUMMARY OF SITE CHARACTERISTICS Section 1 of the Draft Final Site 34 FS Report (F-504) contains an overview of the RI activities conducted at the JETC, and Table 1 in Appendix A of this document presents a summary of RI activities conducted at Site 34. The significant findings of the RI are presented in this subsection. A. Site Geology The bedrock in the vicinity of the JETC (Building 222) has been identified from samples obtained from a total of 26 locations as split-spoon samples, well cuttings, and cores. The identified rock types consist of quartzite, felsite, and diabase. The rock types have been tentatively classified as belonging to the Kittery Formation, the Exeter diorite, and the diabase dikes of the White Mountain Series. The bedrock surface beneath the JETC is irregular, probably as a result of preglacial preferential erosion. Overall, the bedrock ranges from highs of 0 ft BGS (outcrop approximately 15 feet northeast of Building 222) to lows of greater than 45 ft BGS. A bedrock high located under Building 222 is bordered on the east and west by steep-sided, broad valleys. Another bedrock high exists east-northeast of Building 222. The upper few inches to approximately 1 foot of thickness of bedrock at the JETC was found to be weathered and highly fractured, based on cores collected from eight boreholes. The weathered and/or fractured bedrock is probably transmissive and grades downward into a more competent bedrock. A well-sorted gravel that overlies the bedrock ranges from a few inches to more than 1 foot in thickness. The gravel unit usually consists of angular bedrock fragments and was field-identified with the overlying till unit. This suggests that the weathered/fractured zone is widely distributed around the bedrock high located under Building 222. At the JETC, the locations of fractures were determined by use of the very low-frequency electromagnetic method. Bedrock lineaments at the JETC consist of a set of eight lineaments that trend approximately N42 E to N54 E. A second set of four lineaments occurs that trends N11 W to N18 W. Two other lineaments that occur at the JETC have orientations that trend N80 E and N24 W. The lineaments that trend approximately northeast-southwest probably are related to the regional strike of the bedrock, while lineaments oriented to the northwest-southeast are probably related to cross fractures or faults in the bedrock. The lineaments of greatest potential concern for contaminant and water migration near Building 222 are the five lineaments that surround the Building 222 bedrock high. The set of lineaments that trends approximately N45 E may represent fractures, faults, or preglacial drainageways. These lineaments may be paths of least resistance for water migration under and away from Building 222. In addition to the descriptions of the natural fractures, the rock quality determination (RQD) of the core was determined. The RQD of a core is equal to the sum of the length of the core pieces separated by natural fractures that are greater than 4 inches long, divided by the length of cored interval (expressed as a percentage). At the JETC, the RQD values indicate that portions of the bedrock are highly fractured, which is indicative of higher potential for groundwater movement through the rock type. The unconsolidated overburden, except for the weathered bedrock and manmade fill, at Pease AFB appears to correlate with the Wisconsinan age glacial episode. Based on present and historic drilling information at Pease AFB, the stratigraphic units are divided into four units as follows (in descending order from youngest to oldest): • • • • Upper Sand (US). Marine Clay Sand Silt (MCS). Lower Sand (LS). Glacial Till (GT). Each of these units is present at the JETC. The nature and distribution of these overburden units have contributed to the distribution and migration of contaminants into the surrounding area. The uppermost surficial materials observed at the JETC are Recent swamp (i.e., bog or marsh) deposits. These deposits are especially common over the MCS unit, and accumulate in the poorly drained areas only. The thickness of the swamp or peat deposits varies between 1 foot and 2 feet. Locally, these low-lying surficial units have been modified by the Air Force using draining or cut-and-fill practices. Also present at the surface at the JETC are fill materials. The fill material varies from an unconsolidated, tan, fine-to medium-grained sand near the underground storage tanks (USTs) to a highly compacted, reddish brown fill under the flight apron. Unconsolidated sand fill near the USTs and the leaching ?? ranged in thickness from 6 to 8 ft BGS; in places it was present from the ground surface to bedrock. The youngest glacial overburden unit at the JETC is the US. In places, the US is difficult to distinguish from the fill, or where the MCS unit is absent from the LS. The US consists of poorly sorted sand with some silt and gravel at the JETC. At many locations in the vicinity of the JETC, the US has been replaced by fill, especially near the USTs and the flight apron. Stratigraphically underlying ?? US is the MCS. The MCS ranges in thickness from 0 to 22 feet and varies in texture from a dark gray, plastic clay with minor very thin interbeds of silty material to well-laminated ?? bedded, fine ?? and clays. The dark gray, plastic clay and elastic silt is defined as a mappable unit at the JETC as one progresses away from the bedrock high toward bedrock lows. The MCS unit grades into an interbedded fine sand and silt unit near the bedrock high. At the site, contacts between the MCS, US, and LS are gradational. The LS at the JETC consists of a poorly sorted, silty sand, with some medium gravel and sand. The LS was absent only in the vicinity of the bedrock high, near Building 222, where, in the absence of the MCS, granular deposits were considered part of the US unit. The GT was found on-site as a more loosely compacted till located near bedrock lows. At some locations, an interval of well-sorted gravel underlies the GT and was sometimes field-identified as weathered bedrock. B. Site Hydrogeology The three hydrogeologic units that have been identified and evaluated for the JETC area are as follows: • Overburden - The saturated overburden deposits, including artificial fill, but not the basal glacial till. • Shallow Bedrock and Glacial Till - The highly weathered and/or fractured interval of crystalline rock that extends from the base of the lower glacial sand to the top of the competent bedrock. Its thickness is typically 10 to 20 feet. • Deep Bedrock - Generally competent bedrock beneath the shallow bedrock. in unweathered fractures. Groundwater flow is primarily Hydraulic tests and water level data indicate that the hydrogeologic units in the JETC area are hydraulically connected, even though each unit has distinct hydrologic properties. The degree of interconnection at any locality depends on the specific lithology of the overburden, the degree of fracturing and weathering, and the location and amount of groundwater pumping. In the JETC area, under natural conditions, groundwater discharge from all hydrogeologic units is to surface streams. C. Site Source Area General Characteristics Soil contamination is present in four distinct areas at the JETC: the JP-4 Tank Area, the Fuel Oil Tank/Waste Fuel Separator Area, the manhole area, and the holding (septic) tanks area (see Figure 3). This subsection summarizes the contaminants found in these source areas (i.e., area of soil contamination). Additional information regarding the nature and extent of soil contaminants is presented in Subsection 1.5.1 of the Draft Final Site 34 FS Report (F-504). Organic contaminants present in soil at the site consist of three groups of compounds: aromatic VOCs, chlorinated VOCs, and PAHs (SVOCs). One or more of these groups have been detected in surface (0 to 2 ft BGS) soil samples and subsurface (greater than 2 ft BGS) soil samples to a maximum depth of 13 ft BGS. Metals concentrations in subsurface soil present above established background levels coincide with areas of organic contamination and are interpreted as additives in JP-4 fuel and fuel (heating) oil used at the JETC. Principally arsenic, chromium, nickel, and sodium are present in areas of hydrocarbon contamination at concentrations above established background levels. Barium and lead concentrations present in surface soil above background levels are not associated with the JETC source area or JETC activities. The highest levels of organic contamination detected in subsurface soils were in the JP-4 Tank Area. The JP-4 Tank Area is located east of the JETC. Contaminants found in soil in the JP-4 Tank Area consist primarily of aromatic VOCs and PAHs. JP-4 was also identified by FID fingerprint analyses. No incidences of spills or other releases from the JP-4 tank have been reported since its installation in 1970. However, based on the distribution and levels of organic compounds present in soil samples collected adjacent to the tank, the JP-4 tank is the most likely source of the soil contamination in this area. In October 1991, the JP-4 tank was emptied to avert any future potential releases. In addition, contaminants detected along the southeastern edge of the JP-4 Tank Area may be attributable to contaminants that were processed through the leaching field. Figures 4 and 5 are stratigraphic cross sections that show a schematic representation of the distribution of soil contamination for the JP-4 Tank Area, and the relationship between the soil contamination and the groundwater flow system. These figures illustrate that the migration of contaminants in soil is controlled primarily by the slope of the bedrock surface. PAHs are the only organic compounds detected in the Fuel Oil Tank/Waste Fuel Separator Area, which is located adjacent to the southern corner of the JETC. Relatively low (<2 mg/kg) levels of PAHs were found in fill material at sample depths of 4 and 6 ft BGS, and in the MCS unit at a sample depth interval of 4 ft BGS. Since PAHs are common constituents of heating oils, the most likely source of the low levels of PAHs in soil is the abandoned steel heating oil tank. Another possible source of the PAH contamination is the waste fuel separator. JP-4contaminated effluent from the JETC may have been released to the soil through breaches in the separator. Effluent received by the waste fuel separator was normally a mixture of hydraulic fluids, degreasing solvents, JP-4, and emulsifiers. The emulsifiers were used to enhance the solubility of the petroleum-based products that accumulate on the floor of the JETC. Both the heating oil tank and the waste fuel separator were installed in the late 1960s, during JETC construction. Since the heating oil tank was abandoned in 1987 and the waste fuel separator has not been in use since mid-1990, they are no longer a source of soil contamination at the JETC. Soil contamination in the manhole area was detected only in the MCS unit and consisted of PAHs and aromatic and chlorinated VOCs. The primary contributor to total PAH levels in the manhole area is naphthalene. Aromatic VOCs present in the manhole area consist primarily of BTEX compounds. The primary contributors to the total chlorinated VOCs are 1,1,1 -trichloroethane and chlorobenzene. The probable sources of these contaminants are spent solvents used in post-test engine cleaning at the JETC. Washdown liquid containing solvents collected in the test cell floor drains may have been released through breaches in the drainage pipe leading to the stormwater manhole or the waste fuel separator. In addition, contaminants that have accumulated in the manhole area may be migrating to the east, toward the Test Cell Ditch, along the backfilled trench that was completed for drain pipe installation. Soil contamination in the holding tanks area consisted primarily of PAHs and was present only in saturated soil samples (i.e., at the top of the shallow water table). In addition, FID analysis reported target VOCs also present in this area. No identification or quantification of VOCs was reported. Contamination in this area was evident prior to december 1989. Petroleum contamination in saturated soil and groundwater was obvious during holding tank installation. A potential source of soil contamination in this area is contaminated effluent from the manhole area. Contaminant Mobility The fate and transport of contaminants within a soil matrix are dependent on the chemical properties of the contaminants, soil types, stratigraphy, and climatic conditions. Contaminant fate and migration are further controlled by transport and attenuation processes. Important transport processes include surface water and groundwater movement, leaching, and erosion. Attenuation processes include retardation resulting from sorption, volatilization, photooxidation, photolysis, and chemical and biological degradation. The major contaminants found at the JETC are components of JP-4 and fuel oil. Significant components of JP-4 include benzene, toluene, ethylbenzene, xylenes, and other complex aromatic hydrocarbons, such as isopropylbenzene. Naphthalene and phenol compounds are also present. Fuel oil contains many of the same compounds as JP-4 and is predominantly a mixture of straight-chain hydrocarbons, aromatic hydrocarbons (including trimethyl-benzenes), and some PAHs. Fuel oil also may include some additives, which may contain phenols, naphthalenes, and heavy metals, such as nickel, chromium, vanadium, zinc, and arsenic (F-299). The fate of JP-4 in the soil environment is a function of the solubility, volatility, sorption, and degradation of its major components. Because of their high volatility, moderate solubility, and moderate adsorption to soils, the major components of JP-4 and fuel oil are relatively mobile and nonpersistent in soil systems. For JP-4 released to surface soils, volatilization to the atmosphere is the primary fate for most of the JP-4 hydrocarbons (F-299). In cases in which the source of contamination is leaks from UST volatile components do not have an opportunity to evaporate before penetrating the ?? and can possibly enter the water table. Biodegradation of the petroleum hydrocarbons comprising JP-4 fuel is expected to be rapid under conditions favorable to microbial activity, especially in an initially aerobic environment (F-299). Because of lower levels of oxygen and organic carbon, contaminant persistence in deep soils and groundwater may be greater than in shallow soils. Benzene is the most mobile and soluble of the aromatic hydrocarbons, and that portion that does not volatilize, sorb, or degrade will ?? into the groundwater. The other aromatic hydrocarbons are less mobile and may be ?? the soil and groundwater. The PAH compounds, except for the naphthalenes, are strongly sorbed to soils and are slightly mobile to immobile and, therefore, tend to persist in the soil until they are degraded. Thus, these compounds are not likely to be found in the groundwater. D. Groundwater Soil at Site 34 is a concern because of the potential for leaching of organic contaminants to groundwater and surface water Groundwater characteristics are presented as a background for source control activities. A remedy for groundwater will be discussed in the Zone 3 RI and FS Reports. Site Groundwater General Characteristics Physiochemical Considerations Many of the contaminants detected in soil and sediment were also detected in groundwater. These contaminants (mostly aromatic hydrocarbons and naphthalene) have relatively low to moderate mobility and are stable. Contaminants detected in groundwater and not detected or detected at low concentrations in soil or sediment are normally compounds that are highly mobile, such as TCE and DCE, and may have been leached from the soil or migrated from outside the JETC area. JP-4 tends to infiltrate into porous, sandy soils, and since it is lighter than water it tends to accumulate at the soil-groundwater interface. There, the more soluble components dissolve into the groundwater and migrate with the groundwater at a rate determined by their retardation factors until they degrade or are discharged to the surface. In cases in which sufficient amounts of JP-4 have been spilled, a separate light, nonaqueous-phase liquid (LNAPL) may form on the surface of the water table. To date, free-phase product has been observed at only one groundwater monitoring point (piezometer 753) during two rounds of water level measurements (January and April 1989). Relatively low levels of chlorinated VOCs, such as TCE and DCE, have been detected in groundwater samples. These compounds have specific gravities greater than water and may exist as dense, nonaqueous-phase liquids (DNAPLs). However, the fact that the concentrations of these compounds in the groundwater are well below their aqueous solubilities, and the probability that the principal sources of chlorinated VOCs originate outside of the JETC area, suggests that separate dense phases are not likely to exist in groundwater at the JETC. Conceptual Site Model of Migration Pathways Based on hydraulic tests and water level data, the deep bedrock, shallow bedrock, and overburden water-bearing units in the JETC area are hydraulically connected. Although each water-bearing unit has distinct hydrologic properties, there is communication among units. The interaction of the three water-bearing units is due to three site conditions: fracturing and subsequent weathering of the bedrock, overburden deposition, and excavation activities. Field data that support the premise that the three water-bearing units are in communication include: (1) the partial dewatering of the overburden and the shallow bedrock water-bearing units observed when groundwater is pumped from the two bedrock groundwater recovery wells (634 and 635); (2) the lack of clay and silt and the presence of porous fill in direct contact with bedrock observed in soil borings and test pits; and (3) the similarities in the organic chemical composition between groundwater sampled from the deep bedrock water-bearing unit and soil sampled from characterization borings. The migration of contaminants from the unsaturated overburden soils to the shallow groundwater flow zone is enhanced by recharge of stormwater. Water level data do not indicate that groundwater in the JETC area has a specific recharge point or area. In addition, groundwater recharge should be significant in backfilled areas associated with JETC construction and subsequent site modifications (i.e., holding tanks and leaching field installations). Geotechnical analysis of two fill samples collected at the JETC reported porosities of 29% and 40%. Consequently, these fill areas would rapidly absorb stormwater and provide a vertical conduit for groundwater recharge. Furthermore, Building 222 is situated over a bedrock high (bedrock outcrops just east of the building), and much of the adjacent fill areas are relatively thin and unsaturated. Groundwater recharge in these areas is directly into the shallow bedrock water-bearing unit. With the exception of arsenic, the distribution of metals in groundwater in the JETC area is not apparently the result of the leaching of metals in source area soils. This premise will be further evaluated and discussed in the Zone 3 FS Report. Groundwater discharge to surface water bodies within and adjacent to the site is considered an important contaminant migration pathway in the JETC area. The hydraulic gradient in the overburden water-bearing unit indicates that groundwater, in general, flows eastward from the source area and is captured by the Test Cell Ditch and other topographically low areas within the wetlands. The Test Cell, Upper Newfields, and Southern Ditches may receive contaminants through discharges from the overburden groundwater flow zone, from stormwater runoff, or from storm drain discharges (Test Cell Ditch only). Based on the location of the JETC source areas, the overburden groundwater gradient, and stormwater drainage, the Test Cell Ditch is the only plausible surface water pathway for the migration of contaminants originating from the JETC source areas. Since the completion of the sediment/soil removal IRM and the reconfiguration of the JETC drainage system, contaminated effluent is no longer a contributor to surface water or sediment contamination in the Test Cell Ditch. Contaminant levels in the overburden groundwater flow zone are relatively low; groundwater sampled from well 5016 had a detected total VOC concentration of 3.4 ug/L. Therefore, groundwater discharging into the Test Cell Ditch also would have relatively low VOC concentrations, and may be further diluted from stormwater runoff captured by the ditch. This is substantiated by trace levels (3.2 ug/L) of total VOCs found in the surface water at staff gage 806. Groundwater contamination will be more fully evaluated in the Zone 3 RI and FS Reports and will be discussed in the rest of this document only with regard to actual source control issues. E. Surface Water/Sediment Surface water and sediment were not evaluated in the Draft Final Site 34 FS Report. The sediment and surface water are currently under evaluation in the Zone 3 FS Report, which will include the groundwater, sediment, and surface water at the JETC. The delineated wetlands for Site 34 and Zone 3 are presented in Figure 6. A complete discussion of the nature and extent of contamination and contaminant fate and transport is presented in Sections 4 and 5 of the Draft Final Site 34 RI Report. VI. SUMMARY OF SITE RISKS A. Human Health Risk Assessment A BRA was performed to estimate the probability and magnitude of potential adverse human health and environmental effects from exposure to contaminants associated with the site. The public health risk assessment followed a four-step process: (1) contaminant identification, which identified those hazardous substances that, given the specific site conditions, were of significant concern; (2) exposure assessment, which identified actual or potential exposure pathways, characterized the potentially exposed populations, and determined the extent of possible exposure; (3) toxicity assessment, which considered the types and magnitudes of adverse health effects associated with ex??e to hazardous substances; and (4) risk characterization, which integrated the three earlier steps to summarize the potential and actual risks posed by hazardous substances at the site, including carcinogenic and noncarcinogenic risks. The results of the human health and ecological risk assessments for the JETC are discussed in this subsection and the following subsection, respectively. The BRA for this site is limited to the source areas evaluated int?? 34 RI and FS Reports. Nineteen contaminants of concern were selected for 0 to 2 ft B?? and ?? contaminants of concern were selected for 0 to 15 ft BGS soils. The contaminants of concern constitute a representative subset of the more than 21 and 37 contaminants identified at the site for 0 to 2 and 0 to 15 ft BGS soils, respectively, during the RI. The contaminants of concern were selected to represent potential site-related hazards based on toxicity, concentration, frequency of detection, and mobility and persistence in the environment. The contaminants of concern are listed in Tables 2 and 3 in Appendix A. A summary of the health effects of each of the contaminants of concern is presented in Section 6 of the Dra??al Site 34 RI Report. Potential human health effects associated with exposure to the contaminants of concern were ??nated quantitatively or qualitatively through the development of several hypothetical exposure pathways. These pathways were developed to reflect the potential for exposure to hazardous substances based on the present uses, potential future uses, and location of the site. The site is intermittently used for industrial purposes, and future land use is assumed to be industrial. This assumption is based on the current plans of the Pease Development Authority (PDA) to attract industrial tenants to the base as a means of boosting the local economy, because the local economy was adversely impacted by the base closure. Of the three potential receptors (building workers, maintenance workers, and trespassers) for the soil pathway, the maintenance worker was selected as the most reasonable maximally exposed individual (RME) under current and future potential land use. The risk from exposure to surface (0- to 2-foot-deep) soils was ??ated for the current and future maintenance worker, and the risk from exposure to surface and subsurface (0- to 15-foot-deep) soils was evaluated for the future maintenance worker. The exposure routes that were evaluated for the soil pathway were incidental soil ingestion and dermal contact with soil. The following is a brief summary of the exposure pathways evaluated. A more thorough description is presented in Section 6 of the Draft Final Site 34 RI Report. For each pathway evaluated, an average and a reasonable maximum exposure estimate were generated corresponding to exposure to the average and the maximum concentration detected in that particular medium. Currently, the JETC is not being used; however, it is expected that it will resume an industrial use soon, and that the future use of this area will be industrial. The current use receptor chosen as the RME for the soil pathway was the maintenance worker. The current maintenance worker exposure was assumed to be 2 hours/day, 1 day/week, 50 weeks/year, for 25 years. The maintenance worker was also chosen as the future RME for the soil pathway; however, the exposure frequency is greater because the site will be more active in the future. The future maintenance worker is projected to be potentially exposed for 2 hours/day, 250 days/year, for 25 years. Excess lifetime cancer risks were determined for each exposure pathway by multiplying the lifetime averaged dose by the chemical-specific cancer slope factor. Cancer slope factors have been developed by EPA from epidemiological or animal studies to reflect a conservative upper bound of risk posed by potentially carcinogenic compounds (i.e., the actual risk is unknown, but is likely to be lower than the calculated risk). The resulting risk estimates are expressed in scientific notation as a probability (e.g., 1 x 10[-6] for 1/1,000,000) and indicate (using this example) that an average individual is not likely to have greater that a 1-in-1-million chance of developing cancer over 70 years as a result of site-related exposure, as defined, to the compound at the stated concentration. Current EPA practice considers carcinogenic risks to be additive when assessing exposure to a mixture of hazardous substances. The hazard quotient was also calculated for each pathway as a measure of the potential for noncancer health effects. A hazard quotient is calculated by dividing the exposure duration-averaged dose by the reference dose (RfD) or other suitable benchmark for noncancer health effects for an individual compound. Reference doses have been developed by EPA to protect sensitive individuals over the course of a lifetime and to reflect a daily exposure level that is not likely to present an appreciable risk of an adverse health effect. RfDs are derived from epidemiological or animal studies and incorporate uncertainty factors to help ensure that adverse health effects will not occur. The hazard quotient is often expressed as a single value indicating the ratio of the stated exposure, as defined, to the reference dose value. The hazard quotient is only considered additive for compounds that have the same or similar toxic endpoint, and the sum is referred to as the hazard index. (For example: the hazard quotient for a compound known to produce liver damage should not be added to a second whose toxic endpoint is kidney damage). Table 4 in Appendix A depicts both the cancer and/or noncancer risk summary for the contaminants of concern in soil evaluated for the JETC to reflect present and potential future exposure pathways corresponding to the average and the reasonable maximum exposure scenarios. From the summary table, it may be noted that the cumulative cancer risk falls within the EPA-acceptable risk range of 10[-4] to 10[-6]. A majority of the contaminants of concern do not result in an individual risk greater than 10[-6]. Of the several contaminants whose risks do exceed 10[-6], most do not exceed a risk of approximately 10[-5]. A more complete discussion of the risks associated with Site 34 is presented in Section 6 of the Draft Final Site 34 RI Report. The hazard indices for soil were all below the EPA criterion of 1. Because the human health risk due to receptor contact with contaminated soils does not exceed the EPA acceptable risk range, remediation at Site 34 is instead based on the potential of soil contaminants to leach to groundwater and contribute to unacceptable human health risks through the groundwater exposure pathways. At this time of the Draft Final Site 34 FS (F-504), the groundwater risk assessment for Zone 3 (including Site 34) was not complete. However, as of the writing of this ROD, the Draft RI for Zone 3 (F-546) has been completed, and the risk assessment indicates that the human health risks through groundwater exposure pathways at Site 34 exceed acceptable levels. B. Ecological Risk Assessment Because ecological receptors are not likely to regularly come in contact with deep soils, the potential risks to ecological receptors at the JETC were evaluated for surface soils (0 to 2 ft BGS) only. The ecological receptors selected to evaluate potential environmental risks (i.e., the short-tailed shrew and the American robin) were chosen because they are representative of the extensive small mammal and ground-foraging avian communities normally found in this habitat type, shrew and robin exposure includes potential bioaccumulation of contaminants identified in surface soil and their transfer across trophic levels, and adequate data exist to determine the likelihood of impact. Short-tailed shrew and American robin exposure routes evaluated in the ecological risk assessment were incidental soil ingestion and ingestion of earthworms. The potential risks to the short-tailed shrew and American robin were assessed by comparing estimated daily doses with Critical Toxicity Values (CTVs). Hazard quotients were calculated, for each contaminant, by dividing the estimated daily intake by the CTV. Hazard quotients were summed across all exposure pathways for each contaminant to develop specific hazard indices. Contaminant-specific hazard indices (average and maximum concentrations) were then added to provide cumulative hazard indices for the shrew and robin. A hazard index of greater than 1 is usually considered the benchmark for concern. Hazard indices for the short-tailed shrew and American robin are presented in Tables 1.8-1 and 1.8-2 of the Draft Final Site 34 FS Report. The cumulative hazard indices for the shrew ranged from 305 to 951; the primary contributors to these indices were lead and barium intake via the invertebrate (earthworm) ingestion pathway. Neither the average nor the maximum cumulative hazard index for the robin exceeded 1. Concern over the uncertainty associated with the exposure results was expressed in the conclusions of the Draft Final Site 34 RI Report. The main concern was related to the impact of anthropogenic contamination that is not site-related on the outcome of the ecological assessment. Inorganic contaminants such as lead and barium were detected at the highest concentrations in areas adjacent to the vehicle parking area and may be more related to normal airfield operation and general industrial use at the base rather than to site-related activities. When the incremental hazards from these suspected anthropogenic contaminants (lead and barium) are subtracted from the total hazard indices, risks from JETC-related activities approach EPA's target range. Therefore, the ecological receptors at the JETC site were not found to be at risk as a result of site-related contamination. VII. DEVELOPMENT AND SCREENING OF ALTERNATIVES A. Statutory Requirements/Response Objectives Under its legal authorities, the le?? agency's (i.e., Air Force) primary responsibility at NPL and similar sites is to undertake remedial actions that are protective of human health and the environment. In addition, Section 121 of CERCLA establishes several statutory requirements and preferences, including that remedial actions must be protective of human health and the environment; the remedial action, when complete, must comply with all federal and state environmental standards, requirements, criteria, or limitations, unless a waiver is invoked; the remedial action selected must be cost effective and use permanent solutions and alternative treatment technologies or resource recovery technologies to the maximum extent practicable; and a preference for treatment remedies that permanently and significantly reduce the toxicity, mobility, or volume (TMV) of the hazardous substances is a principal element for selection over remedies not involving such treatment. Response alternatives for addressing JETC source areas were developed to be consistent with these Congressional mandates. Based on preliminary information relating to types of contaminants, environmental media of concern, and potential exposure pathways, remedial action objectives were developed to aid in the development and screening of alternatives. These remedial action objectives were developed to mitigate existing and future potential threats to public health and the environment. The remedial response objective for source control actions at the JETC was to minimize leaching of contaminants from the source area soils into groundwater or surface water, thereby reducing the potential for the public to ingest or directly contact contaminated groundwater or surface water that presents a health risk (cumulative cancer risk greater than 10[-4], or a hazard index greater than 1 for each contaminant of concern). Any further reduction in risk through soil exposure pathways would be a benefit; however, risks from direct contact with, or ingestion of, source area soils do not exceed the aforementioned criteria and, as such, remediation based on risk due to site soils is not required. However, as discussed previously, the Draft Zone 3 risk assessment indicates that groundwater at Site 34 does exceed acceptable risk levels and as such source actions at Site 34 are expected to reduce groundwater levels. B. Technology and Alternative Development and Screening CERCLA and the NCP set forth the process by which remedial actions are evaluated and selected. with these requirements, a range of alternatives was developed for the site. In accordance With respect to source control, the FS developed a range of alternatives in which treatment that reduces the TMV of hazardous substances is a principal element. This range included an alternative that removes or destroys hazardous substances to the maximum extent feasible, thus eliminating or minimizing to the degree possible the need for long-term management. This range also included alternatives that treat the principal threats posed by the site but vary in the degree of treatment employed and the quantities and characteristics of the treatment residuals and untreated waste that must be managed, alternatives that involve little or no treatment but provide protection through engineering or institutional controls, and a no action alternative. In Section 3 of the Draft Final Site 34 FS Report, technologies were identified, assessed, and screened based on implementability, effectiveness, and cost. These technologies were placed in the categories identified in Section 300.430(e)(3) of the NCP. Section 4 of the Site 34 FS Report presented the remedial alternatives developed by combining the technologies. The purpose of the initial screening was to reduce the number of potential remedial actions for further detailed analysis while preserving a range of options. Each alternative was then evaluated in detail in Section 5 of the Site 34 FS Report. In summary, of the eight source control remedial alternatives screened in Section 4 of the Site 34 FS Report, five were retained for detailed analysis. The following table identifies the five alternatives that were retained through the screening process: III. DESCRIPTION OF ALTERNATIVES This subsection provides a narrative summary of each alternative evaluated. A detailed tabular assessment of each alternative is presented in Tables 5.2 -1 through 5.2-5 of the Site 34 FS Report. A. Source Control Alternatives Analyzed The source control alternatives evaluated for the JETC were a no action alternative (Alternative 1) and four alternatives involving treatment (Alternatives 2A, 3A, 4, and 5A). Alternative 1 - No Action The no-action alternative was evaluated in detail in the Site 34 FS Report to serve as a baseline for comparison with the other remedial alternatives under consideration. Under this alternative, no treatment or containment of source areas would occur. This alternative does include deed restrictions for the property and a long-term soil monitoring program. The GWTP currently operating at the site would continue to operate until the zonewide groundwater issues are addressed in the Zone 3 RI/FS.

SUMMARY OF THE COMPARATIVE ANALYSIS OF ALTERNATIVES Section 121(b)(1) of CERCLA presents several factors that must be considered when assessing alternatives. Building on these specific statutory mandates, the NCP has promulgated nine evaluation criteria to be used in as?? individual ??medial alternatives. A detailed analysis was performed on the alternatives ?? the nine evaluation criteria to select a site remedy. A summary of the comparison of each alternative's strengths and weaknesses with respect to the nine evaluation criteria is presented as follows. Threshold Criteria The two threshold criteria that follow must be met for the alternatives to be able for selection in accordance with the NCP: 1. Overall protection of human health and the environment addresses whether a remedy provides adequate protection and describes how risks posed through each pathway are eliminated, reduced, or controlled through treatment, engineering controls, or institutional controls. 2. Compliance with Applicable or Relevant and Appropriate Requirements (ARARs) addresses whether a remedy will meet all of the ARARs or other federal and state environmental laws, and/or will provide grounds for invoking a waiver. Primary Balancing Criteria The following five criteria are used to compare and evaluate the elements of one alternative to another that meet the threshold criteria: 3. Long-term effectiveness and permanence addresses the criteria that are used to assess alternatives for the long-term effectiveness and permanence they afford, along with the degree of certainty that they will prove successful. 4. Reduction of toxicity, mobility, or volume (TMV) through treatment addresses the degree to which alternatives employ recycling or treatment that reduces the TMV of contaminants, including how treatment is used to address the principal threats posed by the site. 5. Short-term effectiveness addresses the period of time needed to achieve protection and any adverse impacts on human health and the environment that may be posed during the construction and implementation period, until cleanup goals are achieved. 6. Implementability addresses the technical and administrative feasibility of a remedy, including the availability of materials and services needed to implement a particular option. 7. Cost includes estimated capital, operation and maintenance (O&M), and present-worth costs. Modifying Criteria The modifying criteria that are used in the final evaluation of remedial alternatives generally after public comment on the RI/FS and Proposed Plan are received are as follows: 8. State acceptance addresses the state's position and key concerns related to the preferred alternative and other alternatives, and the state's comments on ARARs or the proposed use of waivers. 9. Community acceptance addresses the public's general response to the alternatives described in the Proposed Plan and RI/FS Reports. A detailed tabular assessment of each alternative according to the nine criteria is presented in Tables 5.2-1 through 5.2-5 of the Site 34 FS Report. Following the detailed analysis of each individual alternative, a comparative analysis, focusing on the relative performance of each alternative against the nine criteria, was conducted. This comparative analysis is summarized in Table 5 in Appendix A. The following subsection presents the nine criteria, including the two modifying criteria not discussed in the FS; a brief narrative summary of the alternatives; and the alternatives' strengths and weaknesses according to the detailed and comparative analysis. A. Overall Protection of Human Health and the Environment The no-action alternative (Alternative 1) would not meet this criterion in its restrictions on property use would preclude use of site groundwater and future source area soils; however, this alternative does not provide any minimization source area soil contaminants to groundwater. Additionally, Alternative 1 does soil contaminant TMV, except by natural processes. entirety. The use of deed activities that could disturb of leaching potential of not result in a reduction in Alternatives 2A, 3A, and 4 provide on-site treatment of contaminated source area soils and, therefore, reduce the potential for contaminant leaching from source area soils to groundwater. This would result in a lower potential for human and ecological receptors to be exposed to contaminated soils. All three alternatives result in a reduction of TMV of source area contaminants in both soil and groundwater. Also, by treating the source area soils on-site, liability is not transferred from the original site to an off-site disposal facility as for Alternative 5A. Alternative 5A also minimizes the leaching of source soil contaminants to groundwater by removing contaminated soils from the site. However, the degree of reduction in TMV of soil contaminants at the off-site treatment/disposal facility is unknown because the process would be determined at the time of remedial design to provide the most-cost-effective solution. Implementation of Source Control Alternatives 2A, 3A, 4, and 5A would ultimately aid in achieving the groundwater cleanup goals that will be presented in the Zone 3 FS Report. B. Compliance with ARARs Each alternative was evaluated for compliance with ARARs, including chemical -, action-, and location-specific ARARs. These alternative-specific ARARs are presented in Appendix F of the Site 34 FS Report. In the long term, all of the source control alternatives, including the no-action/institutional control alternative, would achieve chemical-specific ARARs for soil; however, the alternatives differ in the time it would take to achieve compliance. With the exception of the no-action/institutional control source control alternative (Alternative 1), all of the source control alternatives would meet, in time frames ranging from 1 to 4 years, all soil ARARs. In this time frame, Alternative 1 would, most likely, not comply with the State of New Hampshire requirement that soils containing spills of virgin petroleum products achieve a 1 ppm total BTEX concentration. All other alternatives would meet this requirement. The ability of source control alternatives to achieve chemical specific ARARs in groundwater was not evaluated in the Site 34 FS. However, all alternatives that involve extraction and treatment of groundwater would achieve groundwater treatment goals and/or surface water discharge treatment goals prior to groundwater disposal. It is expected that all alternatives would comply with action- and location-specific ARARs, except the New Hampshire Virgin Petroleum Policy with regard to treated soil disposal. The policy indicates that soil requiring treatment should not be placed within 0.5 mile of a water supply well. As the Haven well is less than the prescribed 0.5 mile, Alternatives 3A and 4 would not meet this location-specific ARAR. However, it should be noted that a groundwater divide exists between Site 34 and the Haven Well, such that contamination from Site 34 groundwater is highly unlikely to reach the Haven Well as the groundwater flow is away from the Haven Well. C. Long-Term Effectiveness Since Alternative 1 would not be effective in reducing contaminant leaching to groundwater, potential human health and environmental risks associated with untreated source area soils would still exist. As previously indicated, leaching would reduce the concentrations of contaminants of concern, but this would require many years to achieve and would result in continuing groundwater contamination. Alternatives 2A, 3A, 4, and 5A all involve removal and/or reduction of contaminant concentrations in source area soil. It is expected that all of these alternatives would achieve a residual soil BTEX concentration of 1 ppm; would, therefore, reduce further unacceptable leaching; and, in turn, would reduce contaminant concentrations in source area groundwater. The 1-ppm total BTEX limit is based on a state policy for virgin of long term protectiveness to human health and the environment and differ primarily in the time required to achieve cleanup goals. Because it is difficult to predict the effectiveness of in situ treatment, it was assumed at this time that this technology could achieve the same degree of organic contaminant removal as alternatives involving excavation and treatment or disposal. All four of the action alternatives would further reduce current risks to human health and the environment resulting from ingestion of, and dermal contact with, contaminated soils. This would be attributable predominantly to the treatment or removal of PAHs, which contribute to human health risks exceeding 10[-6]. Alternatives 4 and 5A would likely provide the greater decreases in risks, since the biological processes in Alternatives 2A and 3A may not provide as significant treatment of PAHs. However, as the risk is below acceptable levels, this does not greatly affect comparative effectiveness. D. Reduction in Toxicity, Mobility, or Volume Through Treatment Because it does not involve treatment of source area soils, Alternative 1 would not provide a reduction in contaminant TMV other than natural attenuation that would occur over many years. It is expected that Alternatives 2A, 3A, and 4 would all provide the same order of magnitude reduction in TMV of source area soil contaminants through treatment. Alternative 5A, which involves excavation and off-site disposal of source area soils, would greatly reduce the volume of soil contaminants present at Site 34; however, the degree of overall reduction in contaminant TMV that would occur at an off-site facility is unknown, as the treatment/disposal method would be determined at the time of remedial design. All of the alternatives that incorporate extraction and treatment of groundwater would involve some reduction in TMV of contaminants in source area groundwater. E. Short-Term Effectiveness Implementation of Alternative 1 involves the fewest short-term impacts on human health and the environment because it does not involve activities that would disturb contaminated soil. However, this alternative would not provide any reduction in source area soil contamination other than natural attenuation that would occur over time; therefore, protection of human health and the environment would not be achieved for many years. Alternatives 3A, 4, and 5A all involve similar short-term impacts on site workers, the surrounding community, and the environment as they all involve excavation and subsequent handling of source area soils. However, because Alternative 5A involves off-site disposal rather than on-site treatment, there may be fewer impacts on site workers and the surrounding community than for Alternatives 3A and 4 because of fewer on-site soil handling activities. However, there would be potential risks to communities associated with accid?? spills that could occur during transport to the disposal facility. Potential impacts on workers and the surrounding community would be associated with the release of vapors (volatile BTEX constituents) and particulates during excavation and soil handling activities. Methods that would be implemented to ensure the protection of workers and area residents during soil excavation and treatment are considered reliable and include use of interim geomembrane covers on exposed source area soils, use of appropriate worker personal protective equipment (PPE), implementation of dust and odor suppression techniques to control fugitive dust emissions, and continuous air monitoring to evaluate site conditions. Implementation of Alternative 2A, which involves in situ treatment of source area soil, would involve fewer short-term impacts on site workers and the surrounding community than Alternatives 3A, 4, and 5A because it does not involve extensive excavation and subsequent handling of source area soils. This alternative may, however, have a greater impact on surrounding wetlands environments because of long-term (2 to 4 years) dewatering of source area soils. The alternatives involving excavation (Alternatives 3A, 4, and 5A) would have a slight impact on the wetlands because approximately 0.25 acre would be excavated and/or used as access to the excavated area and would require restoration. Wetlands deline?? for Site 34 and all of Zone 3 is shown in Figure 6. The area impacted as a result of dewatering for Alternative 2A is difficult to predict; however, restoration would occur naturally when the water table returns to its static level. Potential impacts on wetlands from Alternative 2A will be evaluated after the Zone 3 groundwater modeling effort is completed. Alternatives 3A, ??, and 5A, which involve installation of on-site treatment systems and/or stockpiling of excavated soil, may require clearing of surrounding woodlands. However, precautions would be taken to ?? the impacted areas by using existing cleared areas effectively. Alternative 5A would likely ach?? action sooner than the other alternatives because it involves off-site disposal; however, this would depend ultimately on the time frame over which the disposal facility can accept excavated soils. It is expected that Alternative 4 could achieve protection in one construction season, while Alternative 3A could achieve protection in one or two construction seasons. Alternative 2A would require several years to achieve protection. As previously indicated, Alternative 1 would not achieve protection for many years. F. Implementability Alternative 1 would be the most readily implementable alternative because it involves the fewest remedial activities. Alternative 2A would be the most difficult alternative to implement technically because it involves in situ treatment, which is, in general, not as well-proven and more difficult to control than ex situ treatment processes. This alternative involves numerous activities including dewatering of source area soils, distribution of nutrients, and implementation of SVE. All of these activities would have to be carefully controlled to maintain aerobic degradation. Many site-specific conditions could interfere with the implementation of these activities, thus inhibiting the ability to achieve successful biotreatment of source area soil contamination. Because Alternative 2A also involves more extensive groundwater extraction than the other alternatives, the existing groundwater treatment system would have to be modified, thereby complicating the implementation of this alternative to a greater level than the other remedial alternatives. Alternatives 3A and 4, which both involve excavation and on-site treatment of source area soils, would be similar in ease of implementation. Both of these technologies are fairly well-developed and have been used successfully at other sites. However, site-specific conditions could complicate implementation of these technologies at Site 34. For example, potential site specific difficulties associated with implementation of low-temperature thermal desorption (Alternative 4) may include possible soil handling problems because of high moisture content and/or silty soils that could significantly affect system throughput and cost. Both of these treatment technologies would require preliminary bench-scale and, possibly, pilot-scale testing prior to implementation of the technology. testing are expected. No major technical problems associated with bench- or pilot-scale It is expected that Alternative 5A, which involves soil excavation and off-site disposal, would be the alternative most easily implemented technically, except for Alternative 1. In terms of administrative feasibility, Alternative 4 would be the most difficult alternative to implement administratively because it would likely require the greatest time for obtaining agency permits/approvals. Thermal desorption would require rigorous testing to ensure compliance with applicable air quality requirements. Alternative 5A, which involves off-site disposal of source area soil, would require federal and state agency permits for off-site transportation and disposal, which should be easy to obtain, and consultation with the selected disposal facility to ensure that the excavated material is within specifications. All of the alternatives involve technologies and services that are readily available through multiple vendors. Treatment, storage, and disposal facilities also are readily available to accept treatment residuals. G. Cost The estimated present-worth costs of the alternatives follow: H. State Acceptance NHDES has been involved in oversight of the study of Pease AFB since the mid-1980s, as summarized in Section II. NHDES, as a party to the FFA, has reviewed this document and concurs with the selected remedy. A copy of the Declaration of Concurrence is attached as Appendix C. I. Community Acceptance The comments received during the public comment period and the public hearing on the Proposed Plan and FS are summarized in the Responsiveness Summary (see Appendix D). The selected remedy has not been significantly modified from that presented in the Proposed Plan. X. THE SELECTED REMEDY The remedy selected for the JETC (Alternative 5A) involves the excavation of source area soils (shown in Figure 7), with on-site treatment of groundwater extracted for dewatering purposes. The soil will be sent to an off-site treatment/disposal facility. A remedial process flow sheet for alternative 5A is presented in Figure 8. Several options are available for off-site treatment and/or disposal of contaminated soil at Site 34. The disposal will be in accordance with all applicable regulations at the time of disposal, and the actual method of disposal or treatment will be determined during the design phase. The treatment/disposal options include: • Remote (on-/off-base) treatment/disposal facilities such as: • • • • Incinerators. Low-temperature thermal treatment units. Asphalt batching plants. Landfills. With respect to off-base facilities, it is important to consider possible treatment requirements. EPA's land disposal restrictions and treatment standards would only apply if the contaminated soil were to be classified as a hazardous waste. The soil would be a hazardous waste if it failed the TCLP test and was not considered exempt from RCRA because of the petroleum product exemption. However, JETC soils were tested and did not exceed TCLP criteria and, therefore, would be classified as nonhazardous materials. Total petroleum hydrocarbon (TPH) concentrations in the Test Cell Ditch sediments were in the same range of concentrations (1,000 to 10,000 mg/kg) observed in soil samples from the site. It is therefore reasonable to expect that the site soils would pass the TCLP as a nonhazardous waste, and treatment would not be required before disposal. Subsection 2.2 of the Draft Final Site 34 FS Report discusses the exclusion for petroleum-contaminated media that fail the TCLP. There are at least two commercial landfill ?? the region that would accept the untreated soils. This option would provide strictly for disposal, not treatment, of the contaminated soils. The nearest commercial incinerators designed to treat contaminated soil are located several hundred to more than 1,000 miles from the site. Off-site incineration is not a cost effective method of managing Site 34 soils. Low-temperature thermal treatment, using technology as described for Alternative 4, is a more realistic option than incineration for the off-site treatment of nonhazardous petroleum-contaminated soils. A number of permitted facilities in New Hampshire are capable of providing this service. The soil would be excavated and transported to the treatment facility, and the decontaminated soil could either be returned to the site for backfilling, or used for some other application (e.g., landfill cover). The use of a thermal desorption unit for several sites may be a viable option depending on remediation activities planned for other sites on base. An option that provides for both treatment and resource recovery is the incorporation of the contaminated soils as aggregate into asphalt paving material. There are at least two asphalt batching plants within 50 miles of the site that provide this service, one of which has already been used to treat and dispose of the sediments removed from the Test Cell Ditch. The cost of off-site treatment and resource recovery is comparable with off-site landfill disposal. Asphalt batching or low-temperature thermal treatment appear to be the preferred options for managing Site 34 soils on-base or off-site, provided the assigned facility complies with all permit requirements. The petroleum contaminated soils would have to meet the qualification and quantification standards established by NHDES policy and the specific standards of the treatment facility. NHDES sets minimum requirements for analytical methods, acceptable limits, and frequency of sampling. Based on the Test Cell Ditch sediment removal and disposal, the treatment and disposal of Site 34 soils in an asphalt batching process or on-base thermal desorption unit appears to be feasible. A. Methodology for Soil Cleanup Goal Determination Since only sources of contamination at Site 34 are being addressed at this time, the only medium evaluated in the FS and the ROD are site soils. The need for action on the site soils was initially evaluated for direct human and ecological receptor contact and the potential for soil contaminants to leach to and adversely impact groundwater above applicable standards. Based on data developed in the RI and the BRA, remedial measures to address risk associated with possible human and ecological receptor exposure to source soils are not warranted because present and future risks are within or below EPA's acceptable risk range. However, available data suggest that area soils are a potential source of release of VOCs to groundwater. This potential release may result in an unacceptable risk to human receptors who may come in contact with contaminated groundwater. Therefore, cleanup levels for soils were established to protect the water-bearing unit from potential unacceptable soil leachate. The Summers Model was used to estimate residual soil cleanup goals that are not expected to impair future groundwater quality. Interim cleanup levels for groundwater were used as input into the leaching model. Final groundwater cleanup goals will be developed as part of the Zone 3 FS. Tables 6 and 7 in Appendix A present the input data for the leaching model. If the predicted protective soil cleanup goal concentrations were not capable of being detected with good precision and accuracy, then the practical quantification limits of the common soil analytical methods were selected as the cleanup goals for soils. The contaminants evaluated for potential leaching cleanup goals were the contaminants of concern in soil and contaminants detected in both soil and groundwater. Table 8 in Appendix A summarizes the soil cleanup goals required to protect public health and the water-bearing unit from exceeding standards based on leaching of chemicals from soils to groundwater. The leaching potential was determined for organics only. The Summers Model results were then compared to maximum detected concentrations in soil and to ARAR values. Only one organic contaminant of concern exceeded a Summers Model value. Although 2-Butanone exceeded the leaching-based cleanup goal, it was decided that as only one location exceeded the leaching-based cleanup goal, and 2-butanone is a common laboratory contaminant, it did not warrant remediation. Since the model did not indicate the need for remediation based on leaching potential alone, the soil cleanup goals were based on the NHDES Virgin Petroleum Products Policy, which allowed a maximum value of 1 ppm total BTEX in soil. The NHDES cleanup goals were chosen because this regulation is appropriate for this situation. At the request of EPA Region I, Table 9 in Appendix A was developed and presents the human health risks associated with the soil cleanup goals chosen. It should also be noted at this time that monitor wells in the source area (617 and 6041) clearly indicate that the groundwater at Site 34 is being adversely impacted. It is anticipated that source area activities will help to reduce the groundwater contaminant levels and result in a shorter time required for groundwater remediation. These cleanup levels in soils are consistent with ARARs for groundwater, attain EPA's risk management goal for remedial actions, and have been determined by EPA to be protective of human health and the environment. These cleanup goals must be met at the time of implementation. The area of excavation is shown on Figure 7. B. Groundwater Treatment Goals The target levels developed in the FS are only intermediate values for groundwater treated in conjunction with source control actions; final groundwater remediation objectives have been developed in the Zone 3 Draft FS. At the time of Site 34 FS Report preparation, groundwater was not under evaluation at the JETC; however, groundwater will be evaluated fully in the Zone 3 RI and FS Reports. Target treatment levels for groundwater were developed for groundwater extracted during source area remedial activities. The target treatment levels, presented in Table 10 in Appendix A, are based on MCLs, not site-specific risk-based values. These levels are considered to be target treatment levels only for groundwater extracted for source area remedial activities. The extraction of groundwater during remedial activities is only designed to provide easier access to contaminated soils. Source area groundwater and management of migration groundwater has been addressed in a separate Zone 3 FS document. A risk assessment has been performed on groundwater contamination at the JETC as part of the Zone 3 Draft RI Report to determine whether groundwater remedial action is warranted, and final groundwater cleanup goals have been established for Zone 3 in the Zone 3 Draft Feasibility Study. C. Target Surface Water Discharge Concentrations At the time of Site 34 FS Report preparation, surface water was not fully evaluated at the JETC. water has subsequently been evaluated in the Zone 3 Draft RI and Draft FS Reports. Surface However, target treatment levels for groundwater were developed in the Site 34 Draft Final FS Report for discharge of treated groundwater to surface water during source area remedial activities. The target treatment levels are presented in Tables 2.5-6 and 2.5-7 in the Draft Final Site 34 FS Report, and are based on AWQC, not site-specific risk-based values. These levels are considered to be target treatment levels for surface water discharge of treated groundwater extracted for source area remedial activities. A BRA will be performed on surface water contamination as part of the Zone 3 RI Report to determine whether surface water remedial action is warranted. D. Description of Remedial Components The remedy chosen for the JETC, whose main remedial goal is source control, will involve the following key components: • Excavation of JETC soils that contain contaminant concentrations exceeding site-specific cleanup goals. A mobile laboratory will be on-site to confirm the removal of contaminated material. The excavated material will be temporarily stored and dewatered, on-site, prior to removal to the off-site facility. • The excavation will be backfilled with clean fill to a level that matches existing grade ?? the site. • Excavated contaminated materials will be transported to a treatment/disposal location as soon as scheduling allo?? The type of disposal facility will be chosen (i.e., asphalt batch, RCRA ??), Subtitle D landfill, on-base thermal desorption unit, or other) at the time remedial design based on cost and other factors. • Groundwater extracted as part of the excavation and/or dewatering process will be treated at the existing pilot GWTP. Holding tanks will be provided for storage of groundwater prior to treatment. • Prior to completion of remedial activities, EPA and NHDES will conduct a review as part of the regulatory approval process to ensure that the remedial soil cleanup goals have been me?? Figures 7, 8, and 9 provide a plan of the estimated excavation area, process flow sheet, and available staging area at Site 34, respectively. Detailed descriptions of the various components are provided in this subsection. It is expected that 5,?? yd[3] of soils from Site 34 will be excavated; volumes are presented in the following table. Of the possible total of 5,350 yd[3], up to 1,200 yd[3] may need to be excavated using wet excavation techniques and/or draining of the excavation via pumping from the bottom of the hole. As discussed previously, the final volume removed will be determined at the time of remediation using field screening techniques. The volumes presented are estimated and are subject to field verification. Since a portion of the area to be excavated will result in destruction of adjacent wetlands, erosion and sedimentation controls, as well as careful excavation, will be used in the soil removal in these areas. Any wetlands adversely impacted will be restored. During excavation and temporary storage activities, erosion runoff and VOC and particulate emissions will be controlled via the use of a temporary runoff detention area adjacent to the stockpile, and placement of a geomembrane on the stockpile and sideslopes of the excavation areas. Continuous onsite air monitoring also will be conducted during excavation and stockpiling activities. Some dewatering of the excavation area will occur with the use of well points, which will extract groundwater at a rate of approximately 30 gpm. Following extraction, groundwater will be stored in five 20,000-gallon storage tanks. Groundwater will then be treated at the existing pilot GWTP at Site 34, which consists of potassium permanganate injection in conjunction with greensand filtration for iron and manganese removal followed by activated carbon adsorption for VOCs removal. Treated effluent will meet groundwater treatment goals as presented in Subsection 2.5 of the Site 34 FS Report, and will be discharged to the base sanitary sewer system. Excavated soil could potentially be transported to an asphalt batch facility, RCRA TSD facility, Subtitle D landfill, or an on-base mobile thermal desorption unit. The treatment/disposal method will be chosen during remedial design phase based on cost and analytical testing prior to removal activities, and will reflect the statutory preference for treatment contained in CERCLA Section 121(b). XI. STATUTORY DETERMINATIONS The remedial action selected for implementation at the Pease AFB JETC site is consistent with CERCLA and, to the extent practicable, the NCP. The selected remedy is protective of human health and the environment, attains ARARs, and is cost effective. The selected remedy also may satisfy the statutory preference for treatment that permanently and significantly reduces the TMV of hazardous substances as a principal element. Additionally, the selected remedy uses alternate treatment technologies or resource recovery technologies to the maximum extent practicable. A. The Selected Remedy is Protective of Human Health and the Environment The remedy at the site will permanently reduce the risks posed to human health and the environment by eliminating, reducing, or controlling exposures to human and ecological receptors through treatment and by engineering controls, more specifically: • Excavation of contaminated soil and transport to an offsite treatment/disposal facility will reduce the leaching potential of contaminants from soil to groundwater, which would result in unacceptable levels in groundwater. • Treatment of water extracted during construction dewatering will reduce the toxicity of the water prior to discharge. • Backfilling with clean materials will allow future unrestricted use of the site. B. The Selected Remedy Attains ARARs The selected remedy will attain all of the substantive, nonprocedural requirements of federal and state ARARs. ARARs for Site 34 are set forth in Table 11 of Appendix A to this document which contains a complete list of ARARs, including the regulatory citation, and a brief summary of the requirement, and the action to be taken to attain the requirement. In addition, policies, criteria, and guidelines (to be considered, or "TBCs") will also be considered during the implementation of the remedial action. • Chemical-Specific ARARs. • • Location-Specific ARARs. • • • None Fish and Wildlife Coordination Act (FWCA). State of New Hampshire Regulations. Action-Specific ARARs. • Hazardous Materials Transportation Act (HMTA). • • • • CWA. CAA. State of New Hampshire Regulations. To Be Considered (TBCs) Criteria. • • • • EPA Health Advisories (HAs). EPA Risk Reference Doses (RfDs). EPA Carcinogen Assessment Group Potency Factors. NH Interim Policy for the Management of Soils Contaminated From Spills/Releases of Virgin Petroleum Products. The basewide ARARs document (F-530) identifies ARARs for Pease AFB, and Appendix B identifies those for Site 34, and provides detailed discussions of both ARARs and TBCs. Table 11, in Appendix A of this document, provides a complete list of ARARs and TBC criteria for Alternative 5A, including regulatory citations, requirement synopses, actions to be taken to attain the requirements, and determinations as to whether the requirements represent ARARs or TBCs criteria. Federal and State Drinking Water Regulations. Although not an ARAR, Federal and State Drinking Water Standards were used in the development of soil cleanup goals based on leaching. The drinking water standards were entered into a leaching model to estimate soil concentrations which would not cause groundwater to exceed the drinking water ARARs. Drinking water standards, MCLs and other guidance and criteria to be considered (TBCs) were also used to develop of target cleanup levels for the remediation of groundwater extracted during construction dewatering at the site. Chemical-specific ARARs and risk-based target cleanup levels will be met by extracting the contaminated groundwater within the area of excavation, reducing the potential for leaching. Federal and State Pretreatment Standards. The preferred option is discharge of treated water to the base POTW. Under this option, discharge limits would be based on factors regulated by the POTW's existing NPDES permit, pretreatment regulations, and water pollution control laws. Pretreatment standards would be developed with the POTW. Both the Pretreatment Standards and CWA NPDES will be attained upon successful establishment of pretreatment standards for discharge from the groundwater treatment plant. Federal and State Air Quality Regulations. The treatment technologies proposed in the selected remedy will not create any new sources of airemissions. Therefore, many federal and state regulations governing air quality do not apply to the selected remedy. The only air quality standards that are applicable are particulate standards promulgated under the Clean Air Act and New Hampshire Ambient Air Quality Standards. The particulate standard would apply to remedial construction activities. These standards would be attained through monitoring and, if necessary, use of dust suppression techniques or engineering controls. It is noted that, although the requirements, standards and regulations of the Occupational Safety and Health Act of 1970, 29 U.S.C., et seq. are not ARARs, they will be followed throughout the Site 34 remedial activities where necessary See 55 Federal Register 86 9-80, March 8, 1990. It is also noted that the following New Hampshire requirements and guidance, classified as TBCs, will be followed: NH Administrative Code, EnvWs 411, Control of Underground Storage Facilities; NH Administrative Code, Env-Ws 412, Reporting and Remediation of Oil Discharges; and NH Interim Policy for the Management of Soils Contaminated from Spills/Releases of Virgin Petroleum Products. ?? state requirements and guidance are TBCs because they re?? to the ??-up ?? petroleum products which are not hazardous substances as defined by CERCLA. However, since the soil to be remediated at Site 34 contains such petroleum products, the Air Force will follow the requirements as appropriate. C. The Selected Remedial Action is Cost Effective In the judgment of the Air Force, the selected remedy is cost effective (i.e., the remedy affords overall effectiveness proportional to its costs). Once alternatives that were protective of human health and the environment and th?? her attain or, as appropriate, waive ARARs were identified, the overall effectiveness of each alternative was evaluated by assessing the relevant three criteria: long-term effectiveness and permanence, reduction in TMV of contaminants through treatment, and short-term effectiveness. The relationship of the overall effectiveness of this remedial alternative was determined to be proportional to its costs. A summary of the costs associated with each of the source control remedies is presented as follows. costs are presented in net present-worth costs. All Of the aforementioned alternatives, four attain ARARs and are protective: Alternatives 2A, 3A, 4, and 5A. Alternative 5A is the most cost effective alternative overall, and provides a degree of protectiveness proportional to its cost. Alternative 3A is 7.5% more costly than 5A and does provide slightly more protection to human health and the environment; however, this additional protection is not necessary since the risk to human health and the environment at the JETC is acceptable under both alternatives. Alternative 5A provides greater short-term effectiveness at a lower cost than Alternative 3A or 4. Alternative 5A provides equal or greater long-term effectiveness, reduction in TMV (dependant upon final treatment/disposal chosen at the time of remedial design), implementability, and compliance with ARARs and TBC criteria as Alternatives 2A, 3A, and 4, but at a lower cost. The costs for Alternatives 3A and 5A were very nearly the same; however, the time until remediation is completed is very different. Alternative 3A would require approximately 2 years, while Alternative 5A would most likely not require more than 6 months. Continuous pumping of the water-bearing zone at the high rates required for Alternative 2A could adversely affect wetlands in the area by inhibiting groundwater recharge of the wetlands. Alternative 1 (no action) does not meet ARARs and would not provide any additional protection of human health and environment. A summary of costs for key elements of the selected source control remedy (Alternative 5A) is presented as follows. All costs are net present-worth. Miscellaneous includes mobilization/demobilization, access restrictions, health and safety, air monitoring, and SARA review upon completion. Contingency costs and additions and O&M costs are not listed as they are in the table on the previous page. D. The Selected Remedy Uses Permanent Solutions and Alternative Treatment or Resource Recovery Technologies to the Maximum Extent Practicable Once the Air Force identified those alternatives that attain or, as appropriate, waive ARARs and that are protective of human health and the environment, the Air Force identified which alternative uses permanent solutions and alternative treatment technologies or resource recovery technologies to the maximum extent practicable. This determination was made by determining which alternative provides the best balance of tradeoffs among alternatives in terms of the following issues: (1) long-term effectiveness and permanence; (2) reduction in TMV of contaminants through treatment; (3) short-term effectiveness; (4) implementability; and (5) cost. The balancing test emphasized long-term effectiveness and permanence and the reduction in TMV through treatment, and considered the preference for treatment as a principal element, the bias against off-site land disposal of untreated waste, and community and state acceptance. The selected remedy provides the best balance of tradeoffs among the alternatives. Alternative 5A slightly outranks Alternatives 2A, 3A, and 4 in terms of permanence; however, all four action alternatives (Alternatives 2A, 3A, 4, and 5A) have equal rank in long-term effectiveness. In addition, Alternatives 2A, 3A, and 4 place greater emphasis on treatment, but exceed the cost of Alternative 5A by 57%, 7.5%, and 117.5%, respectively, and do not reduce the TMV of contaminants any more than would Alternative 5A, which would most likely involve resource recovery/reuse technologies. Alternatives 2A, 3A, 4, and 5A involve some upgrades to the Site 34 GWTP that may be incorporated in to the Zone 3 groundwater remediation and as such possibly serve in both capacities. All four action alternatives would result in some adverse impact on wetlands, with Alternative 5A creating less impact because of a shorter time of remediation and less time until restoration occurs. Alternative 1 contains no provision for reduction in TMV of contaminants or for consideration of EPA's preference for treatment as a component of remediation. E. The Selected Remedy and the Preference for Treatment that Permanently and Significantly Reduces the Toxicity, Mobility, or Volume of the Hazardous Substances as a Principal Element The selected remedy may not satisfy the statutory preference for treatment which permanently and significantly reduces the toxicity, mobility or volume of hazardous substances as a principal element depending on the treatment and/or disposal method chosen at the time of implementation. The selected remedy is consistent with EPA's preference for containment of wastes which it is not practicable to treat. The principal element of the selected source control remedy is offsite treatment/disposal of source area soil. This element addresses the primary threat at the site (contamination of groundwater resulting from leaching of source area soils), and complies with the NHDES Policy on Virgin Petroleum Products (F-338). The method of disposal or treatment of the excavated soils will be determined during the remedial design phase. The determination will reflect the requirement of CERCLA 120(b)(1) that states "Remedial actions in which treatment which permanently and significantly reduces the volume, toxicity or mobility hazardous substances, pollutants or contaminants is a principal element, are to be preferred over remedial alternatives not involving such treatment". XII. DOCUMENTATION OF SIGNIFICANT CHANGES The Air Force presented a Proposed Plan (Alternative 5A) for remediation of the site in December 1992. source control portion of the preferred alternative included: The • Excavation of contaminated soil and transport to an approved off-site treatment/disposal facility. It is expected that approximately 5,350 yd[3] of contaminated soils would be excavated. Soil samples would be collected and analyzed as the operation concluded to ensure all soil above the cleanup goals was removed. • Dewatering of the site during soil excavation and treatment of the extracted groundwater at the existing on-site treatment facility, with subsequent discharge to the base sanitary sewer. • Backfilling of the excavation with excavated soil not requiring treatment or clean soil. • Environmental monitoring during remedial operations. • Removal of the remaining USTs and piping from the manhole to the Test Cell Ditch. This tank cluster and any remaining piping at the site will require removal incidental to excavation of the surrounding contaminated soil. There have been no significant changes in the selected alternative since publication of the Draft Final Site 34 FS Report and Proposed Plan other than the removal of the JP-4 tank and the oil/water separator in fall 1992. It should be noted that several regulations have been updated and some are now enforceable, where they were not previously. Appendix B presents Subsection 2.2 of the Draft Final Site 34 FS Report. Regulatory updates, as of the signing of this ROD, have been added to the appendix. XIII. STATE ROLE NHDES, as a party to the FFA, has reviewed the various alternatives and has indicated its support for the selected remedy. The state has also reviewed the Site 34 RI, BRA, and FS to determine whether the selected remedy is in compliance with ARARs. The State of New Hampshire concurs with the selected source control remedy for the JETC. A copy of the Declaration of Concurrence is attached as Appendix C.

The following subsections present and discuss ARARs and other to be considered (TBC) criteria that may affect remediation at Site 34. A list of ARARs appropriate to the preferred alternative selected for detailed evaluation at Site 34 is presented in Table 11, in Appendix B. 2.2.1 Identification of ARARs Identification of ARARs must be performed on a site-specific basis. NCP and SARA do not provide universal standards for determining whether a particular remedial action will produce an adequate remedy at a particular site. Rather, the process recognizes that each site has unique characteristics that must be evaluated and compared to those requirements that apply under the given circumstances. ARARs are defined as follows: • Applicable requirements are those cleanup standards, standards of control, and other substantive environmental protection requirements, criteria, or limitations promulgated under federal, state, or local laws that specifically address a hazardous substance, pollutant, contaminant, remedial action, location, or other circumstance found at a CERCLA site. • Relevant and appropriate requirements are those cleanup standards, standards of control, and other substantive environmental protection requirements, criteria, or limitations promulgated under federal, state, or local laws that, while not "applicable" to a hazardous substance, pollutant, contaminant, remedial action, location, or other circumstance at a CERCLA site, address problems or situations sufficiently similar to those encountered at a CERCLA site. • TBC information refers to other federal and state criteria, advisories, guidance, and proposed standards and local ordinances that are not legally binding, but that may provide useful information or recommended procedures. ARARs may be divided into the following categories: • Chemical-specific requirements are health- or risk-based concentration limits or ranges in various environmental media for specific hazardous substances, pollutants, or contaminants. These limits may take the form of action levels or discharge levels. • Location-specific requirements are restrictions on activities based on the characteristics of a site or its immediate environment. An example is restrictions on wetlands development. • Action-specific requirements are controls or restrictions on particular types of activities in related areas such as hazardous waste management or wastewater treatment. An example is Resource Conservation and Recovery Act (RCRA) incineration standards. Because such requirements are triggered by the particular remedial alternative action considered, and the FS evaluates a wide range of alternative actions, many different action-specific requirements may be applicable. The chemical-, location-, and action-specific ARARs for Site 34 are summarized in Table 2.2-1. 2.2.2 Chemical-Specific ARARs Chemical-specific requirements "set health- or risk-based concentration limits or discharge limitations in various environmental media for specific hazardous substances, pollutants, or contaminants" (52 FR 32496). These requirements generally set protective cleanup levels for the chemicals of concern in the designated media, or indicate a safe level of release that may be incorporated into a remedial activity. Clean Water Act The provisions of CERCLA Section 121 state that remedial actions shall attain federal water quality criteria where they are relevant and appropriate. Federal water quality criteria documents have been published for 65 pollutants or groups of pollutants listed as toxic under the CWA. These criteria are unenforceable TBC guidelines that may be used by states to set surface water quality standards. Although these criteria were intended to represent a reasonable estimate of pollutant concentrations consistent with the maintenance of designated water uses, states may appropriately modify these values to reflect local conditions. The water quality criteria are generally represented in categories that are aligned with different surface water use designations. Most aquatic life that exhibits levels below specified concentrations is protected against acute or chronic effects (24-hour average). Specific criteria have not been established for many chemical compounds because of insufficient data. Table 2.2-2 provides the most recent water quality criteria for the protection of aquatic life and human health. Clean Air Act The CAA was enacted to protect and enhance the quality of air resources to protect public health and welfare. The CAA is intended to initiate and accelerate national research and development programs to achieve the prevention and control of air pollution. Under the CAA, federal agencies are to provide technical and financial assistance to state and local governments for the development and execution of their air pollution programs. EPA is the administrator of the CAA and has the responsibility to meet CAA objectives. CAA requirements are potentially applicable to remedial actions that result in air emissions, such as excavation, landfilling, and treatment activities. National Ambient Air Quality Standards are listed in Table 2.2-3. State of New Hampshire Regulations Groundwater Draft New Hampshire Code of Administrative Rules (NHCAR) and Env-Ws 410 Protection of Groundwater, have been developed and the NHCAR is under the public comment period. The NHCAR rules are not yet enforceable, and EnvWs 410 has been officially adopted and is enforceable, the State of New Hampshire Department of Environmental Services (NHDES) has consistently applied the requirements set forth in these proposed rules and, as such, they are TBCs and ARARs, respectively. The chemical-specific requirements of these rules are discussed in Env-Ws 410.03, Groundwater Quality Criteria, and are presented as follows: • No person shall cause groundwater quality to be altered in any way that would make groundwater unsuitable for use as a source of drinking water. • No person shall cause groundwater to contain any regulated contaminant at concentrations above the groundwater quality standards adopted under the New Hampshire Revised Statutes, Annotated (RSA)485-C:6. • Prior to the adoption of specific groundwater quality standards, no person shall cause groundwater to contain any regulated contaminant in a concentration above the maximum contaminant level established in Env-Ws 310 through 319, or above health advisory levels issued by EPA or the New Hampshire Division of Public Health Services. • No person shall cause groundwater to exceed surface water quality standards, as established in RSA 485-A and Env-Ws 430 through Env-Ws 439, at a point of discharge of groundwater to the surface water body. • No person shall cause degradation of groundwater that results in a violation of surface water quality standards, as established in RSA 485-A and Env-Ws 430 through Env-Ws 439, in any surface water body. Table 2.2-4 presents State of New Hampshire MCLs and MCLGs established in Env-Ws 310 to 319, Drinking Water Quality Standards as well as the advisory levels established by the New Hampshire Division of Public Health and Services (NHDPHS). Regulated SMCLs (established primarily for aesthetic purposes) in Env-Ws 319 are also presented in Table 2.2-4 and will be considered in selecting site-specific groundwater cleanup goals. The aforementioned requirements would apply to new discharges to groundwater outside a Groundwater Management Zone (Env-Ws 410.26), but would not apply to discharges to the groundwater within the capture zone of a groundwater extraction and treatment system associated with remediation of contaminated groundwater under a groundwater monitoring permit. Further discussion of Env-Ws 410, including the state's policy for dealing with sites where groundwater has been contaminated by past discharges (Groundwater Management Zone Policy), is presented in Subsection 2.2.4. Wastewater to POTW NHCAR Env-Ws 900, Part 904, has established pretreatment standards and guidelines for wastes that are discharged to a publicly owned treatment works (POTW). Air Emissions NHCAR Env-A 300, Parts 303 and 304, have established primary and secondary ambient air quality standards (equivalent to federal standards). These requirements are listed in Table 2.2-3 and are summarized as follows: (a) • Particulate Matter The annual arithmetic mean for particulate matter shall not exceed 50 ug/m[3]. The maximum 24-hour average concentration for particulate matter shall not exceed 150 ug/m[3]. • (b) Sulfur Dioxide • The annual arithmetic mean for sulfur dioxide shall not exceed 0.030 ppm or 80 ug/m[3]. • The maximum 24-hour concentration shall not exceed 0.14ppm or 365 ug/m[3] more than once per year. • For secondary standards, the maximum 3-hour concentration shall not exceed 0.5 ppm or 1,300 ug/m[3] more than once per year. (c) Carbon Monoxide • The maximum 8-hour concentration shall not exceed 9 ppm or 10 mg/m[3] more than once per year. • The maximum 1-hour concentration shall not exceed 35 ppm or 40 mg/m[3] more than once per year. (d) Nitrogen Dioxide • (e) For primary and secondary standards, the annual arithmetic mean for nitrogen dioxide shall not exceed 0.05 ppm or 100 ug/m[3]. Ozone • (f) For primary and secondary standards, the maximum 1-hour average concentration of ozone shall not exceed 0.12 ppm or 235 ug/m[3]. Hydrocarbons In order to achieve primary and secondary standards, the maximum 3 consecutive hour concentration, from 6:00 a.m. through 9:00 a.m., of nonmethane hydrocarbons shall not exceed 0.24 ppm or 160 ug/m[3] more than once per year. • (g) Lead • In order to achieve primary and secondary standards, the maximum arithmetic mean averaged over a calendar quarter shall not exceed 1.5 ug/m[3]. NHCAR Env-A, Part 1303, identifies toxic air pollutants to be regulated. These pollutants are also listed by EPA in 40 CFR 61. Toxic ambient air limits (AALs) established for some of the chemicals detected at Site 34 are listed in Table 2.2-3. NHCAR Env-A, Chapters 600, 1000, and 1200, have established standards for the release of air emissions, including VOCs and hazardous air pollutants. Applicable standards include the most stringent of the following requirements: • New Source Performance Standards (40 CFR 60). • National Emission Standards for Hazardous Air Pollutants (40 CFR 61). • New Hampshire State Implementation Plan Limits. See RSA 125-C:6, NHCAR Env-A 101.09, and Env-A 606.01. Remedial action may be necessary to prevent unpermitted air emissions from the site, including volatilization of soil contaminants, during remedial activities. 2.2.3 Location-Specific ARARs Location-specific requirements "set restrictions on activities depending on the characteristics of a site or its immediate environs" (52 FR 32496). In determining the use of these location-specific ARARS to select remedial actions for CERCLA sites, one must investigate the jurisdictional prerequisites of each of the regulations. Basic definitions, exemptions, etc., should be analyzed on a site-specific basis to confirm the correct application of the requirements. A description of Site 34 and its immediate environs is contained in Section 1. Fish and Wildlife Coordination Act The purposes of the FWCA are to conserve and promote conservation of fish and wildlife and their habitats. The FWCA pertains to activities that modify a stream or river and affect fish or wildlife. Actions must be taken to protect those fish and wildlife resources affected by site activities. State of New Hampshire Requirements Wetlands Impact RSA 485-A:17 and Env-Ws 415 establish criteria for conducting any activity in or near state surface waters that significantly alters terrain or may otherwise adversely affect water quality, impede natural runoff, or create unnatural runoff. Activities within the scope of these provisions include excavation, dredging, filling, mining, and grading of topsoil in or near wetlands areas. Remedial activities near or adjacent to wetlands or surface water must comply with these criteria for the protection of state surface waters. RSA 482-A and (Env-Wt) 300 to 400, 600, and 700 regulate filling and other activities in or adjacent to wetlands, and establish criteria for the protection of wetlands from adverse effects on fish, wildlife, commerce, and public recreation. Remedial activities in wetlands located in or adjacent to the site must comply with these wetlands protection requirements. Wellhead Protection Program The New Hampshire Wellhead Protection Program, instituted under RSA 485:48 of the New Hampshire Administrative Code, has been approved by the Council on Resources and Development and EPA. Under the program, wellhead protection areas (WHPAs) for public wells (private homeowner wells are not included in this program) will be delineated and potential groundwater contamination sources (PCSs) within those areas will be identified and managed. The state's program for managing PCSs will include educating industry personnel on management and handling practices that reduce the risk of groundwater contamination. These practices are called Best Management Practices (BMPs). Management inspections will be performed periodically at each identified operation in a WHPA to ensure that BMPs are being used. Rules for these BMPs and the authority to enforce them at the state and local levels are proposed under a draft groundwater classification system for the state. Additional regulatory and nonregulatory tools are available to local governments for the management of PCSs in WHPAs; guidance on these will be made available through the Office of State Planning. 2.2.4 Action-Specific ARARs Action-specific ARARs are technology- or activity-based requirements or limitations on actions taken with respect to hazardous wastes. These requirements are triggered by the particular remedial activities that are selected to accomplish an alternative. Since there are usually several alternative actions for any remedial site, different requirements can come into play. These action-specific requirements do not in themselves determine the remedial alternative; rather, they affect how a selected alternative must be achieved. The distinction between substantive requirements and administrative requirements at a CERCLA site is important when reviewing different action alternatives. Substantive requirements pertain directly to actions or conditions in the environment while administrative requirements pertain to permits that facilitate implementation of a requirement. At CERCLA sites, actions taken on-site are exempt from the administrative requirements. For example, discharge to an on-site stream would be exempt from permit requirements, but discharge to a POTW would not be exempt. Wetlands Protection Through Executive Order No. 11990, regulations regarding protection of wetlands were promulgated by EPA under 40 CFR 6.302. As wetlands areas exist at Site 34, the following action-specific regulatory requirements represent potential ARARs: • Avoid adverse impacts associated with the destruction or loss of wetlands. • Avoid new construction on wetlands unless no other practicable alternative exists. • Prepare a wetlands assessment if wetlands will be affected. • Minimize adverse impacts on wetlands if no practicable alternative to the action exists. Hazardous Materials Transportation Act Through the Hazardous Materials Transportation Act (49 USC 1801 to 1813), regulations regarding the transportation of hazardous materials were promulgated by the Department of Transportation (DOT) under 49 CFR 107 and 171 to 177. If transportation of DOT-defined hazardous materials off-site is a potential remedial action at Site 34, the following action-specific regulatory requirements represent potential ARARs: • Hazardous materials table (49 CFR 172.101). • Required manifest information (49 CFR 172.101, 172.203, and 173). • Transportation mode requirements (49 CFR 172.101 and 174 to 177). • Packaging, labeling, and marking requirements (49 CFR 172, 178, and 179). • Transportation placarding requirements (49 CFR 172, Subpart F). Occupational Safety and Health Act The Occupational Safety and Health Act (OSHA) (29 USCA 651) resulted in creation of the Occupational Safety and Health Administration to protect worker safety and to administer regulatory control for worker safety. Under OSHA, general industry standards have been promulgated under 29 CFR 1910. The action-specific requirements given under 29 CFR 1910.120, Hazardous Waste Operations and Emergency Response, may apply to remedial activities at Site 34. Clean Water Act CWA regulations establish effluent standards for point source discharges as follows: • Direct discharge to a surface water is governed by the National Pollutant Discharge Elimination System (NPDES) permitting requirements (Section 402 of the CWA). Specific permitting requirements are contained under 40 CFR 125, while specific effluent guidelines and standards are given in 40 CFR 401. It should be noted that no categorical effluent guidelines or standards have been established for hazardous waste sites. It should be noted, however, that standards established in 40 CFR 403.6 for various industrial uses may be indirectly applicable to hazardous waste site operations if the types of technologies employed during remediation are similar to the processes used in the regulated industry. • Indirect discharge to a POTW is governed by pretreatment regulations [Section 307(b) of the CWA]. National pretreatment standards are addressed under 40 CFR 403. The standards specifically prohibit discharge of the following items (40 CFR 403.5): • • • • • • Ignitable or explosive wastewater. Reactive or toxic fume-generating wastewater. Used oil. Solvent waste. Pollutants that pass through the POTW without treatment, interfere with POTW operations, contaminate POTW sludge, or endanger the health or safety of POTW workers. Transported pollutants, except at points designated by the POTW. NPDES discharge limitations are based on meeting the following criteria: • Location-specific, federally approved state water quality standards (40 CFR 122.44 and 131.40). • Action-specific best available technology (BAT) economically achievable requirements to control toxic and nonconventional pollutants and best conventional technology (BCT) requirements to control conventional pollutants [40 CFR 122.44(a)]. However, technology-based limitations may be determined on a caseby-case basis. Compliance with established limitations is based on discharge monitoring of pollutant mass, effluent volume, and frequency of discharge (40 CFR 122.41). Approved sampling and test methods must be used for monitoring (40 CFR 136.1 to 136.4). Discharge of CERCLA waste waters to a POTW would constitute an off-site activity and, thus, is subject to all permitting requirements and local pretreatment requirements. When considering discharge of CERCLA waste waters to a POTW, the POTW's record of compliance with its NPDES permit and pretreatment program requirements must be assessed to determine whether the POTW is a suitable disposal site for CERCLA wastewater. EPA's Groundwater Protection Strategy for the 1990s In July 1989, EPA established a Groundwater Task Force to review EPA's groundwater protection programs and to develop concrete principles and objectives to ensure effective and consistent decision making in all EPAactivities affecting the resource. The outcome of this effort is a report entitled, Protecting the Nation's Groundwater: EPA's Strategy for the 1990s. Since this policy is intended to direct the course of EPA's efforts in the coming years, it has the potential to significantly affect any action taken to remedy contaminated groundwater at Pease AFB, which in turn may impact groundwater and source area remediation at Site 34. Specific components of this policy that may significantly affect groundwater remediation at Pease AFB are summarized as follows: EPA's Groundwater Protection Principles • The overall goal of EPA's groundwater policy is to prevent adverse effects on human health and the environment and to protect the environmental integrity of the nation's groundwater resources. • In determining appropriate prevention and protection strategies, EPA will also consider the use, value, and vulnerability of the resource, as well as social and economic values. Thus, in decision making, EPA must take a realistic approach to restoration based on actual and reasonably expected uses of the resource as well as social and economic values. • The primary responsibility for coordinating and implementing groundwater protection programs has always been and should continue to be vested with the states. An effective groundwater protection program should link federal, state, and local activities in a coherent and coordinated plan of action. EPA's Policy on Use of Quality Standards in Groundwater Protection and Remediation Activities • MCLs under the SDWA will be used as reference points for water resource protection efforts when the groundwater in question is a potential source of drinking water. • When MCLs are not available, EPA Health Advisory numbers or other approved health-based levels are recommended as points of reference. • Water quality standards under the CWA will be used as reference points when groundwater is closely connected hydrologically to surface water ecological systems. • In certain cases, MCLGs under the SDWA, or background levels, may be used in order to comply with federal statutory requirements. • In general, remediation will attempt to achieve a total lifetime cancer risk level in the range of 10[-4] to 10[-6] and exposures to noncarcinogens below appropriate reference doses. More stringent measures may be selected based on such factors as the cumulative effect of multiple contaminants, exposure from other pathways, and unusual population sensitivities. Less stringent measures than the reference point may be selected where authorized by law based on such factors as technological practicality, adverse environmental impacts of remediation measures, cost, and low likelihood of potential use. Clean Air Act The CAA (42 USC 7401 et seq.) mandates EPA to establish regulations to protect ambient air quality. As such, it may be applied as an ARAR to Site 34 for remedial actions that potentially result in air emissions. Under the CAA, three areas were identified for regulation: • Establishment of National Ambient Air Quality Standards (NAAQS). • Establishment of maximum emission standards as expressed under the National Emission Standards for Hazardous Air Pollutants (NESHAP). • Establishment of maximum emission standards as expressed under the New Source Performance Standards (NSPS). NAAQS and NESHAP represent chemical-specific requirements (see Table 2.2-3). The NSPS contain action-specific requirements. The CAA was amended in 1990; however, most of the final rules to support this amendment have not yet been issued. It is expected that the new rules will include expanded permit requirements and maximum available control technologies for hazardous waste facilities. State of New Hampshire Regulations Hazardous Waste Regulations The hazardous waste rules for the State of New Hampshire are presented in the NHCAR, Subtitle Env-Wm. These rules establish a hazardous waste permit program and a mechanism for monitoring hazardous wastes subject to other regulatory programs, such as NPDES. A waste is considered hazardous by NHDES if it is listed in Env-Wm 400 of the Hazardous Waste Rules or is listed in 40 CFR 261. A waste also may be considered hazardous if it exhibits any of the ignitability, corrosiveness, reactivity, or TCLP characteristics set forth in 40 CFR 261. These provisions establish standards applicable to the identification, listing, and delisting of hazardous waste; permitting; inspection; enforcement; and recycling requirements. These rules also set requirements for owners and operators of hazardous waste facilities, and transporters and generators of hazardous waste. These regulations may be applicable or relevant and appropriate for remedial activities at Site 34. Any activity involving handling or moving a waste or soil and debris determined to be hazardous may involve Env-Wm Hazardous Waste Rules. Solid Waste Requirements State of New Hampshire requirements for solid waste management are Rules. NHCAR Env-Wm 100 to 320 and 2100 to 2800. These provisions treatment, storage, and disposal of solid waste and the closure of waste on-site must be managed, stored, treated, and disposed of in Act and the rules there under. contained in the New Hampshire Solid Waste establish standards applicable to the solid waste facilities. Nonhazardous solid accordance with the Solid Waste Management Underground Storage Tank Requirements State of New Hampshire requirements for the installation, permitting, testing, operation, maintenance, and closure of USTs are contained in the NHCAR, Env-Ws 411, General Requirements for Tanks at Underground Storage Facilities. These regulations outline procedures and requirements for management of underground storage facilities, including the following: • • • • • • • • • • Facility Registration (Env-Ws 411.04). Permit to Operate (Env-Ws 411.07). Transfer of Facility Ownership (Env-Ws 411.08). Inventory Monitoring (Env-Ws 411.11). Tank Tightness Testing (Env-Ws 411.13). Spill/Overfill Protection (Env-Ws 411.25). Release Detection for Tanks Without Secondary Containment and Leak Monitoring (Env-Ws 411.29). Corrosion Protection for Steel Tanks (Env-Ws 411.32). Permanent Closure (Env-Ws 411.18). Secondary Containment for New Tanks (Env-Ws 411.23). These regulations apply to tanks with capacities greater than 110 gallons that store regulated substances, including motor fuels, heating oils, lubricating oils, other petroleum products, and petroleum-contaminated liquids and hazardous substances. These regulations would apply to the JP-4 and oil/water underground tanks at Site 34. If remediation activities at the site involve testing, retrofitting, or removal of USTs, these activities will be executed in accordance with the aforementioned requirements. The State of New Hampshire has also developed a guidance document entitled, Interim Policy for the Management of Soils Contaminated from Spills/Releases of Virgin Petroleum Products (NHDES Virgin Petroleum Products Policy). This policy identifies options for treatment, current analytical methods, and remediation goals for virgin petroleum-contaminated soils. Remediation of soils at Site 34 that have been contaminated by virgin petroleum products will be handled in accordance with this policy. Remediation goals established for virgin petroleum-contaminated soil are as follows: Gasoline • • Benzene, toluene, ethylbenzene, and xylene (BTEX) - 1.0 ppm. Total petroleum hydrocarbons (TPHs) - 10.0 ppm. Diesel fuel or other fuel oils • • BTEX - 1.0 ppm. TPHs - 100.0 ppm. According to NHDES, remediation goals for soil contaminated with JP-4 would be the same as those presented for diesel and other fuel oils. Currently, NHDES does not have a formal policy for the handling of soils contaminated by hazardous wastes or waste oils resulting from the operation of underground storage systems. These materials will be dealt with in a future NHDES policy document. Groundwater As previously indicated, the State of New Hampshire has adopted Groundwater Protection Rules (Env-Ws 410). These rules present the state's policies and procedures for dealing with new discharges of contaminants to groundwater and to groundwater already contaminated by past discharges. Air Emissions The air emissions requirements of the State of New Hampshire are summarized as follows: • • • • • • • • Demonstrating Conformance (Env-A 101.26). Testing and Monitoring Procedures (Env-A 800.07 and 800.09). Malfunctions/Breakdowns of Air Pollution Control Equipment (Env-A 902). Fugitive Dust Emission Control (Env-A 1002). Incinerator Emission Standards (Env-A 1201). Control of VOC Emissions (Env-A 1204). Impact Analysis and Permit Requirement (Env-A 1305). Toxic Air Pollutants (Env-A 1300). Water Resources Water resource requirements of the State of New Hampshire are as follows: • Water Use Registration - Env-Wr 700, Part 701. Users of 20,000 gallons of water or more per day over 7 days or 600,000 gallons over 30 days must register with the Water Resources Division. Water flow measurements are defined in Part 702. Remedial activities involving the use of these quantities of water must comply with the requirements of this section. Safety Relevant safety requirements promulgated by the State of New Hampshire include the New Hampshire Department of Safety Rules for Transport of Hazardous Materials (Safety Ch. 600). These regulations govern the transport of hazardous materials and wastes. They must be complied with when removal action requires off-site transportation of hazardous waste. Water Discharge Requirements The water discharge requirements of the State of New Hampshire are summarized as follows: • New Hampshire Industrial and Municipal Wastewater Discharge Permits (Env-Ws 403). • Pretreatment Standards (Env-Ws 904).

Babbitt Deputy for Hazardous Materials and Waste; Deputy Assistant Secretary of the Air Force (Environment, Safety and Occupational Health) Suite 5C866, Pentagon Washington, D.C. 20330-1660 RE: Site 34 Source Area Record of Decision Pease Air Force Base Superfund Site Pease Air Force Base, New Hampshire Subject: Declaration of Concurrence Dear Mr. Babbitt: The New Hampshire Department of Environmental Services (NHDES) has reviewed the September 1993 Record of Decision (ROD) regarding Source Area Remedial Action at Site 34 - the Jet Engine Test Cell at the Pease Air Force Base Superfund Site located in Newington and Portsmouth, New Hampshire. The intent of the source control action is to reduce the potential lea groundwater, surface water and sediment contamination will be addressed in the Zone 3 ROD. A description of the source control actions, together with NHDES' position follows: I. Excavation of contaminated soil from the JP-4 Tank Area, the Fuel Oil Tank/Waste Fuel Separator Area, the manhole area and holding tanks area, and transport to an approved off-site treatment/disposal facility. The final volume of soil to be removed will be determined at the time of remediation using field screening techniques. Removal of USTs and drain piping from the manhole to the Test Cell Ditch will also be incorporated into the source control action. As noted in the NHDES, "Interim Policy for the Management of Soils contaminated from Spills/Releases of Virgin Petroleum Products", soil excavation and treatment is one of many appropriate remedial methods which minimizes transfer of contaminants from one environmental medium to another. Treatment in a thermal desorption process system, treatment and resource recovery at a NHDES permitted asphalt batch plant, as well as, disposal in a specifically authorized RCRA Subtitle D Landfill or RCRA facility are accepted methods for processing virgin petroleum contaminated soils. Field screening of the excavation will be conducted in accordance with Section VII -Sampling and Analysis Protocols of the NHDES Policy on Virgin Petroleum Contaminated Soils. Any wetlands adversely impacted by the source control action will be restored, subject to the provisions of RSA 482-A and Env-Wt 100 through Wt 800. II. Dewatering of the site during soil excavation and treatment of the extracted groundwater at the existing on-site treatment facility, with subsequent discharge to the base sanitary sewer. The discharge of treated groundwater from the Pilot Groundwater Treatment Plant to the base sewer will require the development of discharge limits in coordination with the City of Portsmouth (operator of the base wastewater treatment plant) in order to ensure compliance with the existing National Pollution Discharge Elimination System permit, pretreatment regulations and water pollution control laws. III. Environmental monitoring: Long-term monitoring will be necessary in order to determine the effectiveness of the source control action. Water quality monitoring is determined on a site specific basis and will be addressed in the Zone 3 ROD. Frequency and location of water quality monitoring is typically required on a tri-annual basis until a baseline condition is established. A comprehensive, detailed review will be conducted by the Air Force, the USEPA and the NHDES within five years after remediation to ensure the remedy provided adequate protection of human health and the environment. Based upon its review, NHDES has determined the source area remedial action to be consistent with applicable or relevant and appropriate state requirements and policies. NHDES, as a party to the Pease Air Force Base Federal Facility Agreement, and acting as agent for the State of New Hampshire, concurs with the selected remedial action. Sincerely, Robert W.

It is not the officially approved abstract drafted by the EPA Regional offices. Once EPA Headquarters receives the official abstract, this text will be replaced. The 4,365-acre Pease Air Force Base, Sites 8, 9 and 11, site is located in the Towns of Newington and Greenland and in the City of Portsmouth, in Rockingham County, New Hampshire. Pickering Brook is the primary surface water pathway that carries runoff away from the site toward the Piscataqua River. In addition to Pickering Brook, several wetlands area exist northeast of site 11. Peverly Brook, an approximate 10-acre emergent wetlands, is located west of Site 9. Groundwater occurs in both the bedrock and overlying unconsolidated deposits at Pease AFB. The bedrock in the vicinity of Pease AFB is composed of metamorphosed sedimentary, volcanic, and intrusive igneous rocks of the Proterozoic to lower Ordovician age Merrimac Group. This group includes the Kittery and Eliot Formations, which are variably composed of quartzite, phyllite, and metagraywacke. Land uses at Pease AFB since its closure on 31 March 1991 include industrial/commercial, military, and a wildlife refuge. Land use in areas immediately surrounding the site varies. Sites 9 and 11 are bounded by the runway and Taxiway D to the south and southeast, and by undeveloped forested land to the northeast. The site was used between 1956 and 1991 and is currently inactive. There are approximately 3,700 dwellings within a 1-mile radius of Pease AFB. Site 9 (Construction Rubble Dump 1) served as a soil borrow area and disposal site for construction debris, including concrete, asphalt, wood, tree stumps, brush, and scrap metal. Phase I records indicate that disposal of construction debris in the area began in 1958; however, there is no evidence of this type of disposal in the 1960 or 1962 aerial photographs. The 1974 and 1987 aerial photographs show a small circular excavation pit on the site. Currently, Site 9 is not in use. A taxiway and north ramp of the flightline form the southwestern and southeastern boundaries of the Site 11 (Fuel Maintenance Squadron) area of investigation. The site was chosen based on evidence of stressed vegetation, organic vapors detected in the surface soil, and disturbed areas. The Phase I study suggested that, prior to 1971, solvents used to remove the protective cosmoline coating from new aircraft parts may have been intermittently disposed of at the site. Site 8 was active as a fire training area from 1961 to 1988. The majority of the fire training exercises were performed in a large circular pit area located in the southeastern portion of the site. Small and large aircraft crash fires were simulated using approximately 200 and 500 to 1,000 gallons of JP-4 fuel, respectively. Prior to 1971, mixed waste oils, solvents, and fuels were collected from drums and bowers located across the base and transported to Site 8 as the main method of disposal. The pit area was first presaturated with water, and then the waste oils, solvents, and fuel were poured on top of the water and onto mock aircraft. The mixture was allowed to burn for 1 to 2 minutes and was extinguished using an aqueous film-forming foam. During the mid 1970s, the practice of mixing waste oils and solvents with fuel for training fires ceased, and only JP-4 fuel was used. The Stage I investigation, which began in 1984, was designed to identify potential impacts of previous site activities and to investigate potential soil contamination at Site 11. Stage 2 field work was performed from October 1987 through May 1989. The primary purposes of the Stage 2 investigation were to characterize the source areas and to delineate the extent of contamination in the groundwater. Stage 4 field work was conducted at Sites 9 and 11 from 1991 to 1993. The objectives of the Stage 4 activities were to assess the extent of contamination in soil and groundwater to support the risk assessment at Site 9 and to select additional soil and groundwater samples at Site 11 to support a No Further Action Decision Document. This ROD presents the selected remedy at Sites 9 and 11. There were no contaminant source materials identified at Sites 9 and 11, thus, no further action is warranted under CERCLA. Remedy: The selected remedial action for this site is no further action because the Baseline Risk Assessment has shown that risk-based levels are not exceeded and the site poses no unacceptable risk to human health and the environment.

Enforcement History at Pease AFB In 1976, the Department of Defense (DOD) devised a comprehensive control migration of environmental contamination that may have re operations and disposal practices at DOD facilities. In response Conservation and Recovery Act (RCRA) of 1976 and in anticipation issued a Defense Environmental Quality Program Policy Memorandum dated June 1980, requiring identification of past hazardous waste agency installations. The program was revised by DEQPPM 81-5 (11 which reissued and amplified all previous directives and memorand Pease AFB was proposed to be added to the NPL in 1989 and was lis 1990. On 24 April 1991, the Air Force, U.S. Environmental Protec NHDES signed a Federal Facilities Agreement (FFA) establishing th timetable for conducting the Remedial Investigation/Feasibility S Pease AFB. As part of this timetable, the Air Force, in an effor designed a basewide strategy plan for conducting an RI/FS.

Typical Superfund sites involves activities to remove or isolate contamin conjunction with activities that mitigate migration of contaminat and/or surface water pathways. Sites 9 and 11 have been investigated under the Air Force IRP beg records search that identified the sites as areas of potential so could be released to the environment. During Stages 1, 2, and 4, analyses were performed to characterize surface and subsurface co 11 and their vicinity. The results of these investigations show materials were identified at Sites 9 and 11. The baseline risk assessment for Site 9 indicated that the cancer resulting from incidental ingestion of, and dermal contact with, or surface water (filtered and unfiltered) at the site did not ex of 10-6 to 10-4, and the total hazard index for human receptors f scenarios did not exceed EPA's benchmark of concern of 1. Both c risks posed by bedrock groundwater were within acceptable ranges compounds and either filtered or unfiltered (total) inorganic com cancer risk posed by exposure to overburden groundwater (organic compounds) from filtered groundwater samples was slightly greater 99% of this calculated risk was due to the presence of arsenic. posed by arsenic in Site 9 overburden groundwater is lower than t the current Maximum Contaminant Level (MCL). MCLs are enforceabl based drinking water standards. The ecological risk assessment i adverse health effects on ecological receptors resulting from inc dermal contact with, soil, surface water, or sediment are expecte The potential for contaminants to leach from soil into groundwate receptor ingestion of, or direct contact with, contaminated water This evaluation indicated that existing concentrations of chemica soil, subsequent to leaching, would not result in groundwater con groundwater Remedial Action Objectives (RAOs). RAOs are defined conceptual goals of remedial actions, such as compliance with App Appropriate Requirements (ARARs) or reducing risks. A baseline risk assessment was prepared as part of the Site 11 NF contaminant levels detected at the site pose unacceptable risks t receptors. The results of the risk assessment indicated that soi do not pose an unacceptable human health risk, or an unacceptable risk. In all media, for both sites, a comparison of site-specific chemi regulatory criteria and/or background concentrations revealed tha concentrations are within these criteria. The concentrations of several metals from unfiltered groundwater CRD-1 exceeded regulatory guidelines. These elevated levels are sampling artifacts and are not representative of actual condition EPA resampled four CRD-1 groundwater monitor wells using a low-fl to confirm the actual metals concentrations at the site. The res concentrations were well below regulatory guidelines. In additio filtered groundwater samples from CRD-1 wells have consistently b levels. Based on this assessment, no further action at Sites 9 and 11 is However, mitigation/elimination of potential physical hazards ass construction debris at Site 9 will be performed under NHDES closu construction debris landfills, independent of CERCLA. V. SUMMARY OF SITE CHARACTERISTICS Section 1 of the Draft Final Zone 5 RI Report (G-635) contains an activities conducted at Sites 9 and 11.

Geology This subsection provides a brief summary of basewide and site-spe A more detailed description of Zone 5 geology is presented in the Report (G-635). Bedrock Geology The bedrock in the vicinity of Pease AFB is composed of metamorph volcanic, and intrusive igneous rocks of the Proterozoic to lower Group. This group includes the Kittery and Eliot Formations, whi of quartzite, phyllite, and metagraywacke. The Eliot Formation comprises the bedrock underlying Site 9, wher primarily of phyllite and metagraywacke, commonly interbedded on The phyllite is light to medium gray, chlorite-quartz-sericite ph phyllite, commonly with gray quartzite or metagraywacke laminatio The phyllite is moderately to strongly foliated with crenulations tan-weathering, medium to dark gray, light green-gray, fine-to-me chlorite-sericite-quartz-feldspar metagraywacke.

Distribution of Contamination Site 9 Soil Quality Throughout the three stages of investigation at Site 9, soil samp suspected to be potential contaminant sources. During these inve debris was identified at the site. The soil quality at Site 9 do significantly affected by the construction debris or by previous whether contaminant concentrations in the soil were related to pr could impact human health or the environment, the detected concen to background concentrations and a risk assessment was performed. appropriate, the detected concentrations were compared to EPA and criteria. In general, relatively low concentrations and sparse occurrences detected at the northern and western portions of CRD-1. The VOCs samples were present at low concentrations. Total petroleum hydr detected at two locations at concentrations above NHDES guideline contamination. Only one of the locations, however, contained TPH above background concentrations. Semivolatile organic compounds (SVOCs) were detected at eight of locations at Site 9. The presence of these SVOCs is likely attri debris such as asphalt. Low concentrations of pesticides were de samples, and the levels detected did not pose unacceptable risks receptors. With the exception of isolated, low-concentration detections of S with asphalt in soil collected at CRD-1, the contamination distri be related to known site activities.

The contaminated groundwater at Site 8 wil Site 8 remedial action. With the exception of contamination asso bedrock groundwater plume, bedrock VOC contamination at CRD-1 is contaminants, and is not believed to be associated with Site 9 ac this contamination has not been identified at CRD-1. No SVOCs or detected in overburden groundwater samples. Site 9 Surface Water and Sediment Quality Peverly Brook is located west of CRD-1, with its headwaters immed runway. Polynuclear aromatic hydrocarbons (PAHs) and TPHs were d samples collected from Peverly Brook, but, based on the hydrogeol contaminants are most likely related to deposits from jet engine used on the runway light supports, rather than disposal activitie concentrations detected in the surface water and sediment at this occurring, and are not related to site activities. One organic c detected in a single surface water sample. However, the presence related to aircraft takeoffs and landings and not to site-related sediment quality in the wetlands and Upper Peverly Brook do not a affected by CRD-1 activities. Site 11 Soil Quality Throughout the three stages of investigation at Site 11, soil sam suspected to be potential contaminant sources. Based on these in contaminant source was identified at the site. Furthermore, the not appear to be significantly affected by the reported site acti the compounds detected in soil were related to previous site acti human health or the environment, the detected contaminant concent compared to background concentrations established for off-base so was performed.

To evaluate whether contaminant concentrations in related to previous site activities or could impact human health concentrations were compared to background concentrations obtaine assessment was performed. In addition, where appropriate, the de were compared against EPA and NHDES regulatory criteria. Based o of groundwater samples collected from six monitor wells, and on t background and risk-based concentrations, the groundwater quality affected by past site activities. Metals were detected in Site 11 unfiltered groundwater samples at regulatory guidelines. However, these elevated levels are most l sediment, which also affected the detected metals concentrations concentrations of several metals from unfiltered groundwater samp exceeded regulatory guidelines. These elevated levels are most l artifacts and are not representative of actual conditions at CRDresampled four CRD-1 groundwater monitor wells using a low-flow s confirm the actual metals concentrations at the site. The result concentrations were well below regulatory guidelines. In additio filtered groundwater samples from CRD-1 wells have consistently b levels. Nitrate/nitrite was detected in one groundwater sample from Site 1988 at a concentration that exceeded the nitrate/nitrite MCL. N in subsequent samples from the same well at concentrations below concentrations of trichloroethene (TCE) were detected in groundwa from one piezometer. The absence of this compound in soil sample site suggests that its presence also is localized. In addition, groundwater flow directions between Site 8 and 11 indicate that t detected at the one location at Site 11 do not originate from Sit VI. SUMMARY OF SITE RISKS Human health and ecological risk assessments were performed to es and magnitude of potential adverse human health and environmental to contaminants associated with Sites 9 and 11 in Zone 5. The hu assessment followed a four-step process: 1. Contaminant identification, which identified those haza given the specifics of the site, were of significant co 2. Exposure assessment, which identified actual or potenti characterized the potentially exposed populations, and of possible exposure. 3. Toxicity assessment, which considered the types and mag health effects associated with exposure to hazardous su 4. Risk characterization, which integrated the three earli the potential and actual risks posed by cancer risks. The results of the baseline human health and ecological risk asse are discussed in the subsections that follow. Site 9 A baseline risk assessment was prepared as part of the RI to eval concentrations in Zone 5 soil, groundwater, surface water, or sed risks to human and ecological receptors. The risk assessment for following current and future use scenarios. Under current land u inactive), access to Site 9 is limited to maintenance workers and worker was selected as the current RME for the soil pathway for S maintenance worker was assumed to be more likely than a trespasse contact with soil on a regular basis. Because groundwater is not a current RME was not selected for the groundwater pathway. It w future land use of Site 9 will continue as industrial. Site 9 is runway, which will continue to operate in the future. Therefore, inactive in the future, serving only as an access route to the ru runway lights. Future receptors at Site 9 would be limited to ma trespassers. Therefore, a maintenance worker was chosen as the f pathway for Site 9. An off-base resident was selected as the fut groundwater pathway for Site 9. The results of the risk assessme summarized in this subsection. Human Health Risk The results of the baseline risk assessment for Site 9, completed that no unacceptable adverse health effects on human receptors re ingestion of, or dermal contact with, contaminated soil sediment, expected. Cancer risks are within EPA's acceptable risk range of indices are less than 1. Both cancer and noncancer risks posed by bedrock groundwater are ranges. The cancer risk posed by exposure to overburden groundwa (ranging from approximately 1 x 10-4 to 5 x 10-5). More than 99% presence of arsenic. Arsenic is naturally occurring at Pease AFB concentrations below the MCL (50 µg/L). Consequently, the calcul arsenic in Site 9 overburden groundwater is lower than that posed MCL. At the current MCL for arsenic, the lifetime cancer risk to drinking water ingestion is calculated to range from approximatel Ecological Risk The baseline risk assessment for Site 9 indicated that no signifi on ecological receptors resulting from ingestion of, or contact w expected. The total hazard indices for ecological receptors asso did not exceed 1. The total hazard indices for the ecological re surface water were greater than 1, but were less than 10 based on concentrations. A hazard index between 1 and 10 is subject to in toxicity of the chemical and the uncertainty in the calculation. and the more uncertainty in the risk calculation, the less concer indices between 1 and 10. The primary contributor to chronic sur total risk) in Peverly Brook was aluminum, wich exceeded criteria Hazard indices for ecological receptors as a result of exposure t The primary contributors to sediment risk were PAHs and pesticide quotients for pesticides detected in Peverly Brook sediments, bas ER-M values, exceeded 10.

Given the single exceedance of a hazard quotient of 10 for pe exceedances of a hazard quotient of 1 for PAHs as determined by e the ecological risks for sediments were found to be at an accepta The baseline risk assessmest, presented in Section 6 of the Draft (G-635), is available in the Administrative Record at the Pease A Repository. Site 11 A baseline risk assessment was prepared as part of the NFADD to e contaminant levels detected at Site 11 pose unacceptable risks to receptors. The risk assessment for Site 11 was based on the foll use scenarios. Because of the proximity of Site 11 to the aircra it was assumed that future use of Site 11, as with current use, w commercial/industrial use (i.e., residential development would no worker was chosen as the RME for the soil pathway. A future offselected as the RME for the groundwater pathway. Groundwater is Site 11. The results of the risk assessment are summarized in th Human Health Risk The results of the risk assessment revealed that exposure to soil pose a risk (either cancer or noncancer) to potential current or above the EPA threshold criteria. Cancer risks are within EPA's 10-4 to 10-6, and hazard indices are less than 1. Ecological Risk Ecological risk was determined for representative ecological spec maximum reported concentrations for the chemicals in surface soil concentrations for only one compound (4,4'-DDT). While 4,4'-DDT reported concentration does present a potential risk to ecologica only positively identified (0.037 J mg/kg) in one 0- to 2-foot-de VII. STATUTORY DETERMINATION A. Rationale for Selecting No Action at Site 9 The statutory determinations required by CERCLA Section 121 for r applicable because risk-based levels are not exceeded at Site 9. The baseline risk assessment conducted during the RI at Site 9 (s the basis for concluding that Site 9 poses no current or potentia health or the environment. More information on the baseline risk in the Draft Final Zone 5 RI Report (G-635). Concentrations of c environmental media at the site do not create human health and en resulting from exposure to site-related contaminants exceeding EP Therefore, no action is required under CERCLA. B. Rationale for Selecting No Action at Site 11 The statutory determinations required by CERCLA Section 121 for r applicable because risk-based levels are not exceeded at Site 11. The baseline risk assessment, as described in Section VI, conduct provides the basis for concluding that the conditions at Site 11 future threat to human health or the environment. The human heal risks do not exceed EPA's acceptable ranges. Groundwater quality and federal primary drinking water standards and ambient water qu minimal surficial contamination observed at Site 11 did not excee guidelines. Therefore, no further action is required. More info assessment is presented in the IRP Site 11 NFADD (G-619). The cu controls on the property, as stipulated by the FFA in the airport ensure that the Site 11 area will only be used consistent with th in Section VI. VIII.

It is not the officially approved abstract drafted by the EPA Regional offices. Once EPA Headquarters receives the official abstract, this text will be replaced. The 4,365-acre Pease Air Force Base, Sites 8, 9 and 11, site is located in the Towns of Newington and Greenland and in the City of Portsmouth, in Rockingham County, New Hampshire. Pickering Brook is the primary surface water pathway that carries runoff away from the site toward the Piscataqua River. In addition to Pickering Brook, several wetlands area exist northeast of site 11. Peverly Brook, an approximate 10-acre emergent wetlands, is located west of Site 9. Groundwater occurs in both the bedrock and overlying unconsolidated deposits at Pease AFB. The bedrock in the vicinity of Pease AFB is composed of metamorphosed sedimentary, volcanic, and intrusive igneous rocks of the Proterozoic to lower Ordovician age Merrimac Group. This group includes the Kittery and Eliot Formations, which are variably composed of quartzite, phyllite, and metagraywacke. Land uses at Pease AFB since its closure on 31 March 1991 include industrial/commercial, military, and a wildlife refuge. Land use in areas immediately surrounding the site varies. Sites 9 and 11 are bounded by the runway and Taxiway D to the south and southeast, and by undeveloped forested land to the northeast. The site was used between 1956 and 1991 and is currently inactive. There are approximately 3,700 dwellings within a 1-mile radius of Pease AFB. Site 9 (Construction Rubble Dump 1) served as a soil borrow area and disposal site for construction debris, including concrete, asphalt, wood, tree stumps, brush, and scrap metal. Phase I records indicate that disposal of construction debris in the area began in 1958; however, there is no evidence of this type of disposal in the 1960 or 1962 aerial photographs. The 1974 and 1987 aerial photographs show a small circular excavation pit on the site. Currently, Site 9 is not in use. A taxiway and north ramp of the flightline form the southwestern and southeastern boundaries of the Site 11 (Fuel Maintenance Squadron) area of investigation. The site was chosen based on evidence of stressed vegetation, organic vapors detected in the surface soil, and disturbed areas. The Phase I study suggested that, prior to 1971, solvents used to remove the protective cosmoline coating from new aircraft parts may have been intermittently disposed of at the site. Site 8 was active as a fire training area from 1961 to 1988. The majority of the fire training exercises were performed in a large circular pit area located in the southeastern portion of the site. Small and large aircraft crash fires were simulated using approximately 200 and 500 to 1,000 gallons of JP-4 fuel, respectively. Prior to 1971, mixed waste oils, solvents, and fuels were collected from drums and bowers located across the base and transported to Site 8 as the main method of disposal. The pit area was first presaturated with water, and then the waste oils, solvents, and fuel were poured on top of the water and onto mock aircraft. The mixture was allowed to burn for 1 to 2 minutes and was extinguished using an aqueous film-forming foam. During the mid 1970s, the practice of mixing waste oils and solvents with fuel for training fires ceased, and only JP-4 fuel was used. In 1983, a study identified that Site 8 was a potential source for the release of contaminants into the environment. From 1984 through 1992, investigations were conducted in three stages. Stage 1 investigation, which began in 1984, was designed to identify potential impacts of previous fire training activities on soil and groundwater. From October 1987 to May 1989, Stage 2 was conducted which was designed to characterize the source areas and to more accurately delineate the extent of groundwater contamination. Stage 3 activities were performed from September 1989 to June 1993 and included two interim remedial measures and a pilot-scale soil vapor extraction (SVE) treatability study. The results of the SVE treatability study demonstrated the effectiveness of SVE as a remedial technology for soil at Site 8. Pease Air Force Base was listed on the NPL in 1990. In 1991, EPA and New Hampshire Department of Environmental Services (NHDES) signed a Federal Facility Agreement (FFA) establishing the protocol and timetable for conducting the RI/FS process at Pease AFB. This ROD addresses Site 8 which discusses both source control measures and management of migration of contaminated groundwater to minimize the leaching of potential soil contaminants. Remedy: The selected remedy includes in situ soil vapor extraction (SVE) treatment of source area soil contaminated above cleanup goals, and treatment of extracted soil vapor for removal of volatile organic compounds (VOCs); construction of an asphalt concrete cap to minimize rainfall and snowmelt infiltration into the area of SVE treatment; the cap will help to minimize the moisture content of the soil to be treated by SVE; recovery and off-base disposal of free-phase product floating on the water table in the source area; design of a groundwater recovery system to capture dissolved-phase contamination in overburden groundwater that exceeds cleanup goals and to prevent continued migration of contaminated groundwater to the bedrock groundwater; construction of an on-site groundwater treatment plant (GWTP) for long-term treatment of recovered groundwater; and environmental monitoring.

The exact date on which this change occurr was most likely after the pit was refurbished in 1974. Refurbishment of the large circular pit occurred from 1974 to 1975, and installation of a sprinkler and drain system. An underground sprinkler- installed that allowed JP-4 to be sprayed onto the pit area through an u An 8-inch-diameter drain pipe, approximately 200 feet long, was construc the burn pit. Excess fuels and fire training materials eventually disch into a drainage ditch at the northern end of the site. In 1983, an Installation Restoration Program (IRP) Phase I Problem Ident Search was conducted at Pease AFB (G-84). The study identified Site 8 a source for the release of contaminants into the environment. In respons presurvey was conducted to obtain sufficient information for use in the detailed study. The presurvey was completed in 1984. Based on the pres conducted at Site 8 and 18 other IRP sites at Pease AFB in accordance wi Comprehensive Environmental Response, Compensation, and Liability Act (C amended; the NCP; and all relevant EPA guidance, including EPA's guidanc RI/FSs under CERCLA. The investigations were conducted in three stages through 1992. The Stage 1 investigation at Site 8, which began in 1984, was designed t impacts of previous fire training activities on soil and groundwater qua results of those investigations were presented in the IRP Phase II - Con Quantification, Stage 1 Final Report for Pease AFB (G-525), submitted in Stage 2 field work at Site 8 was performed from October 1987 through May primary purposes of the Stage 2 investigation were to characterize the s more accurately delineate the extent of groundwater contamination. The investigations are described in detail in four Interim Technical Reports MK01\RPT:00628026.003\site8rod.txt 4) (G-530; G-531; G-536; G-537) and in the IRP Stage 2 Draft Final Repor Force Base (G-533). Soil-gas and soil sampling and aerial photograph re conclude that the former burn areas at Site 8 were potential source area organic compounds (VOCs). During fire training exercises, surface runof discharged from the former burn areas to the drainage ditch located nort burn areas. Based on this information, the ditch was identified as a se source. Stage 3 activities at Site 8 were performed from September 1989 through include the Site 8 RI/FS, two interim remedial measures (IRMs), and a pi vapor extraction (SVE) treatability study. Site 8 RI activities include test pit investigations; surface and subsurface soil sampling; groundwat sediment sampling; historic aerial photograph reviews; and hydrogeologic provides a summary of RI activities performed to date at Site 8. The Dr and FS Reports were submitted in November 1992 and January 1993, respect The first IRM was performed in February and March 1990 and involved the approximately 262 tons of contaminated soil from a drainage ditch locate northeastern corner of the site. main burn pit. This drainage ditch received surface r The purpose of the soil removal IRM was to prevent poten contaminants from the relatively highly contaminated drainage ditch soil groundwater. The excavated soil was disposed of off base at a licensed facility. The second IRM is a pilot groundwater remediation system, which has been since August 1990. The groundwater remediation IRM was designed to init off-site dissolved VOC migration and to evaluate a pump-and-treat system source control measure. Data collected during the operation of the grou IRM were used in the preparation of the FS Report, and will be used for remedial action at the site. MK01\RPT:00628026.003\site8rod.txt The pilot groundwater remediation system consists of extraction wells, a treatment plant (GWTP), and subsurface recharge trenches.

A explanation of the pilot groundwater remediation system is presented in Groundwater Treatment Plant Report (G-552). To date, the pilot groundwa system has extracted and treated approximately 5.1 million gallons of co groundwater, and has recovered approximately 1,100 gallons of free-phase subsurface at Site 8. After preparation of the FS, which proposed SVE and other treatment tech remediate contaminated soils at Site 8, the Air Force performed a pilotstudy to evaluate the effectiveness of SVE as part of the remedy selecti results of the SVE study demonstrate the effectiveness of SVE as a remed soil at Site 8, and are detailed in the Site 8 Soil Vapor Extraction Tre Report (G-680). The results of the SVE study will be used to help estab for a full-scale SVE system at Site 8. B. Enforcement History In 1976, the Department of Defense (DOD) devised a comprehensive IRP to control migration of environmental contamination that may have resulted operations and disposal practices at DOD facilities. In response to the Conservation and Recovery Act (RCRA) of 1976, and in anticipation of CER MK01\RPT:006280260.003\site8rod.txt issued a Defense Environmental Quality Program Policy Memorandum, dated (DEQPPM 80-6), requiring identification of past hazardous waste disposal agency installations. The program was revised by DEQPPM 81-5 (11 Decemb which reissued and amplified all previous directives and memoranda on th Pease AFB was proposed to be added to the NPL in 1989 and was listed on 1990. On 24 April 1991, the Air Force, U.S. Environmental Protection Ag NHDES signed a Federal Facility Agreement (FFA) establishing the protoco for conducting the RI/FS process at Pease AFB. As part of this timetabl in an effort to streamline activities, designed a basewide strategy plan RI/FS. This strategy plan grouped the various sites into seven zones or based on geographic location, potential receptors, and potential future inclusion of Pease AFB on the NPL, five sites (including Site 8) were on RI/FS approach because of the potential threat they posed to human healt environment. The Air Force, EPA, and NHDES agreed that the RI/FS Report five sites and the remedial actions would continue on an accelerated sch remaining RI/FS Reports for each zone have been prepared as outlined in III. COMMUNITY PARTICIPATION Throughout the site's recent history, there has been community concern a EPA, NHDES, and the Air Force have kept the community and other interest apprised of site activities through informational meetings, fact sheets, public meetings. In January 1991, the Air Force released a community relations plan that to address community concerns and keep citizens informed and involved du activities. This plan was updated and released in summer 1993. Numerous fact sheets have been released by the Air Force throughout the AFB. These fact sheets are intended to keep the public and other concer MK01\RPT:00628026.003\site8rod.txt apprised of developments and milestones in the Pease AFB IRP.

SCOPE AND ROLE OF OPERABLE UNIT OR RESPONSE ACTION Zone 5 encompasses three sites, including the operable unit for Site 8. are Sites 9 and 11. The locations of these sites are shown in Figure 1. Remediation at a Superfund site typically involves activities to remove contaminant source materials in conjunction with activities that mitigat contamination through groundwater and/or surface water pathways. This R both source control measures and management of migration of contaminated at Site 8. In general, the maximum extent of soil contamination is within 500 feet areas horizontally and from the surface to approximately 30 feet below g BGS) vertically. The majority of soil contamination consists of aromati (AHCs) (e.g., benzene and toluene) and total petroleum hydrocarbons (TPH Groundwater in both the overburden and bedrock water-bearing zones has b by past activities at Site 8. In the overburden, two distinct plumes ar a plume of free-phase product that is floating on the water table. Obse borings, piezometers, and monitor wells across the site indicate that th may exist in multiple, isolated pockets within a narrow band extending f areas northward to Merrimac Drive. The second plume contains dissolved (both aromatic and chlorinated VOCs) and extends from the former burn ar boundary, the Newington Town property, and the properties owned by Harve Coleman. The locations of these properties are shown in Figure 2b. In phase product has been detected; however, a plume of dissolved VOC conta been detected that originates at Merrimac Drive and extends northwest of Newington Town property. There are two surface water bodies in the vicinity of Site 8: Brook. Pickering Pesticides, polynuclear aromatic hydrocarbons (PAHs), and metals MK01\RPT:00628026.003\site8rod.txt in Pickering Brook. Low levels of VOCs and PAHs also were detected in t samples from Knights Brook. The selected remedy for Site 8, as described in the Draft Final Site 8 P (G-679), provides for the potential combination of two source area remed evaluated in the FS and for management of contaminant migration in the o bearing zone. The primary source area remedial alternative consists of source area soil (Alternative SC-3 in the Draft Final Site 8 FS Report) secondary source area action is installation of downgradient groundwater Also included in this alternative is recovery and off-base disposal of f management of dissolved-phase contaminant migration in the overburden wa zone, on-site treatment of recovered groundwater, discharge of treated g subsurface recharge trenches, and institutional controls. Specifically, alternative includes the following elements: In situ SVE of source area soil with contaminant concentratio cleanup goals. This includes installing vapor extraction ven vacuum on the vents to remove VOCs from the soil. The vapors from the soil will be treated to remove VOCs. Construction of an asphaltic concrete cap (blacktop pavement) rainfall and snowmelt infiltration into the area of SVE treat will aid in lowering the water table. The cap will be instal existing clearing at the source area. The area will be limit minimal disturbance of the Newington Town Forest.

The figure was prepared from data recorded on 20 Jan which time recovery wells 562A, 563, 564, and 566 had not been operating water level elevations were the highest recorded over a 12-month period. measured from hybrid wells are included in Figure 4 for reference only a in developing the contours. Where appropriate, water elevation data wer effect of free-phase product. In the former burn areas, groundwater flows principally from east to wes of the bedrock trough along a horizontal gradient of 0.01 ft/ft. Near t former burn areas, the groundwater flow direction changes to the north-n horizontal gradient decreases to 0.002 ft/ft. Farther to the north, gro directed to the northeast, toward Pickering Creek, where the horizontal to 0.03 ft/ft. Groundwater elevations in the overburden were observed to fluctuate 2 to The highest groundwater elevations typically occurred in the spring and the lowest groundwater elevations typically occurred in the late summer MK01\RPT:00628026.003\site8rod.txt A series of aquifer and laboratory tests was conducted to characterize properties of the overburden at Site 8. The hydraulic testing included pumping tests, and long-term pumping tests in the overburden and bedroc spoon samples were tested using a flexible-wall permeameter to calculat conductivity. Vertical hydraulic conductivities also were calculated f but were considered to be inaccurate because the soil samples used in t composited and recompacted, thereby destroying the horizontal structure hydraulic conductivity estimated from the slug and pumping tests ranged ft/day, and the geometric mean was 4.11 ft/day.

The second test, conducted d 1993, was performed at pumping rates between 16.5 and 15.8 gpm, resulti approximately 9 feet of drawdown in well 562A. The average results of and recovery data analyses yielded an estimated transmissivity of 9,980 hydraulic conductivity of approximately 1,275 ft/day. Bedrock Hydrogeology The bedrock at Site 8 consists of weathered and/or fractured (shallow) competent bedrock. All Site 8 bedrock wells were completed in competen the exception of monitor wells 6021, 6083, and 513, which were construc bedrock wells. Bedrock integrity influences the permeability of the bedrock. Factors bedrock integrity include chemical and physical weathering and fracture Weathering and shallow fracturing are limited in areal extent across Si the shallow bedrock is likely less important as a discrete hydrogeologi MK01\RPT:00628026.003\site8rod.txt <IMG SRC 0194093D> elsewhere at Pease AFB. For example, weathered bedrock was observed in rock cores collected from Site 8, and shallow fracturing was observed in from Site 8. Competent bedrock in the vicinity of the site has negligible primary (in thus, movement of groundwater in the competent bedrock is directly relat structural fabric (i.e., bedding plane separations, foliation patterns, sets). Lithologic heterogeneities in the bedrock (e.g., diabase dikes) groundwater flow locally, but are expected to have little influence on r groundwater flow. Groundwater elevations in the bedrock at Site 8 typically range from 95 FDTA-2 to 86 ft MSL west of FDTA-2, near monitor wells 620 and 637. Fig the Draft Final Site 8 FS Report (G-611) is a potentiometric elevation c on measurements in bedrock wells collected on 20 January 1992. In the b groundwater flows toward the west and northwest across the site. Horizo range from 0.008 ft/ft across Site 8 to 0.03 ft/ft northwest of Site 8 t Similar to overburden groundwater, groundwater elevations in the bedrock feet seasonally. The highest groundwater elevations typically occur in summer, while the lowest elevations occur in late summer and fall. The hydraulic properties of the bedrock water-bearing zone at Site 8 wer slug test data collected from well 513, the results of three short-term results of the long-term (48-hour) pumping test at well 622. Appendix I Site 8 FS Report (G-611) contains the results of the long-term pumping t bedrock well 622. The hydraulic conductivity of the competent bedrock r slug tests and short-term pumping tests ranged from 0.02 to 0.30 ft/day, mean was 0.13 ft/day. However, data collected from the long-term pumpin indicated that the mean hydraulic conductivity of the competent bedrock 4 ft/day. The results of the long-term pumping test are considered to b MK01\RPT:00628026.003\site8rod.txt representative of actual site conditions since studies have indicated th (i.e., the longer the duration) of a pumping test, the greater the perme (G-93). The higher hydraulic conductivity value estimated from the long is attributed to the interception of more fractures during longer term t porosity of the competent bedrock is estimated at 0.001 based on the res term pumping test at well 622. Groundwater seepage rates were estimated for the bedrock water-bearing z range of horizontal hydraulic gradient values (0.008 to 0.03 ft/ft), a h value of 4 ft/day, and a range of effective porosity of 0.01 to 0.001. and these input values, the estimated bedrock groundwater seepage rates from 3.2 to 120 ft/day.

The l extents of AHCs and TPHs beneath the three source areas are shown in a s maps (Figures 5 through 7) that represent the area from the ground surfa approximately 30 ft BGS. The highest concentrations of TPHs and AHCs in (0 to 5 ft BGS) were detected in the center of the two former burn areas MK01\RPT:00628026.003\site8rod.txt <IMG SRC 0194093E> <IMG SRC 0194093F> 09/16/ <IMG SRC 0194093G> contamination extending away from the former burn areas toward the north field investigation, free-phase product was observed in wells 510, 540, (see Figure 7), and soil contamination (TPHs and AHCs) probably exists a 15 ft BGS, near the water table. Thus, although soil analytical results depths greater than 15 ft BGS for the northern portion of the free-phase deeper soil contamination (AHCs and TPHs) is assumed to be associated wi phase product observed near the water table.

Oxygenated hydrocarbons (OHCs) were detected north of the two former bur smaller former burn area, and southwest of the larger former burn area. detected in Site 8 soil include isophorone, vinyl acetate, 4-methyl-2-pe acetone, and 2-butanone. The highest concentration of OHCs (34,000 æg/k 2-pentanone) was detected in boring 714 at 7 ft BGS. None of these comp detected in Site 8 groundwater. The distribution of PAHs at Site 8 appears to be limited to the former b some PAHs were detected from 0 to 2 ft BGS south and west of the former Naphthalene and 2-methylnaphthalene were the most commonly detected PAHs soil. Phenanthrene, pyrene, and chrysene also were detected at several general, PAHs were detected in the former burn areas, to depths of 26.5 water table. PAHs are known components of JP-4, and the occurrence of P strongly with the occurrence of elevated levels (>100 mg/kg) of TPHs in Naphthalene is the most mobile of the PAHs detected at Site 8, and is th to migrate to the groundwater. Naphthalene and 2-methylnaphthalene were detected in groundwater at the highest concentrations. Site 8 soil was originally sampled for total dioxins.

The receptors and exp evaluated in the ecological risk assessment are presented in Table 24. The potential risk posed to ecological receptors (i.e., deer mouse, chip aquatic communities) was assessed by comparing estimated daily doses or concentrations with critical toxicity values (CTVs) or appropriate mediu values. Hazard quotients were calculated, by contaminant, for each rece estimated daily intake by the CTV, or, when medium-specific criteria wer concentrations were compared directly to criteria to determine the corre quotient. Hazard quotients were summed across all exposure pathways for contaminant, by receptor, to develop specific hazard indices. A hazard index of less than 1 indicates adverse effects are not likely t is required. A hazard index of greater than 10 indicates that risks are and action is usually required. A hazard index between 1 and 10 is subj MK01\RPT:00628026.003\site8rod.txt based on the toxicity of the chemical and the uncertainty in the calcula the chemical, and the more uncertainty in the risk calculation, the less with hazard indices between 1 and 10.

DEVELOPMENT AND SCREENING OF REMEDIAL ALTERNATIVES Statutory Requirements/Response Objectives Section 121 of CERCLA establishes several statutory requirements and pre including the following: remedial actions must be protective of human h environment; remedial actions, when complete, must comply with all feder stringent state environmental standards, requirements, criteria, or limi is invoked; the remedial action selected must be cost-effective and use and alternative treatment technologies or resource recovery technologies extent practicable, and a preference for remedies in which treatment tha significantly reduces the toxicity, mobility, or volume (TMV) of the haz is a principal element over remedies not involving such treatment. Reme were developed to be consistent with these mandates. Based on preliminary information relating to types of contaminants, envi of concern, and potential exposure pathways, remedial action objectives developed to aid in the development and screening of alternatives.

SUMMARY OF THE COMPARATIVE ANALYSIS OF REMEDIAL ALTERNATIVES Section 121(b)(1) of CERCLA presents several factors that must be consid assessing remedial alternatives. Building on these specific statutory m promulgated nine evaluation criteria to be used in assessing individual A detailed analysis was performed on the alternatives using the nine eva select a site remedy. A summary of the comparison of each alternative's weaknesses with respect to the nine evaluation criteria is presented as in Table 32 in Appendix E. A detailed comparison of alternatives is pre 5 of the Draft Final Site 8 FS Report (G-611). Threshold Criteria The two threshold criteria that follow must be met for the remedial alte eligible for selection in accordance with the NCP: 1. Overall protcetion of human health and the environment addres remedy provides adequate protection and describes how risks p each pathway are eliminated, reduced, or controlled through t engineering controls, or institutional controls. 2. Compliance with Applicable or Relevant and Appropriate Requir (ARARs) addresses whether a remedy will meet all of the ARARs federal and state environmental laws, and/or will provide gro invoking a waiver. MK01\RPT:00628026.003\site8rod.txt 09/16/ Primary Balancing Criteria The following five criteria are used to compare and evaluate the element to another that meet the threshold criteria: 3. Long-term effectiveness and permanence addresses the criteria assess alternatives for the long-term effectiveness and perma along with the degree of certainty that they will prove succe 4. Reduction of toxicity, mobility, or volume (TMV) through trea the degree to which alternatives employ recycling or treatmen the TMV of contaminants, including how treatment is used to a principal threats posed by the site. 5.

Implementability addresses the technical and administrative f remedy, including the availability of materials and services implement a particular option. 7. Cost includes estimated capital, operation and maintenance (O present-worth costs. Modifying Criteria The modifying criteria that are used in the final evaluation of remedial generally after public comments on the RI and FS Reports and Proposed Pl are as follows: 8. State acceptance addresses the state's position and key conce preferred alternative and other alternatives, and the state's ARARs or the proposed use of waivers. 9. Community acceptance addresses the public's general response alternatives described in the Proposed Plan and RI and FS Rep MK01\RPT:00628026.003\site8rod.txt 09/16/94 A detailed tabular assessment of each alternative according to the nine in Tables 5.2-1 through 5.2-8 of the Draft Final Site 8 FS Report (G-611 Following the detailed analysis of each alternative, a comparative analy relative performance of each alternative against the nine criteria, was comparative analysis is summarized in Table 32. The following subsections describe the nine criteria, including the two discussed in the Draft Final Site 8 FS Report (G-611); a brief narrative alternatives; and the alternatives' strengths and weaknesses according t comparative analysis. A. Overall Protection of Human Health and the Environment Overall protection of human health and the environment addresses how an a whole will protect human health and the environment. This includes an how human health and environmental risks are properly eliminated, reduce through treatment, engineering controls, or institutional controls. The preferred alternative (Alternative 4) for remediating contamination designed to provide overall protection by preventing continued leaching from soil containing contaminant concentrations exceeding cleanup goals groundwater. This will be accomplished by removing VOCs from soil via S recovering free-phase product using the skimmer pumps and, potentially, recovery trench. Alternative 4 also is designed to prevent further migr groundwater via groundwater extraction. All the other alternatives, exc action/institutional control alternative (Alternative 1), also are prote and the environment. MK01\RPT:00628026.003\site8rod.txt 09/16/ B. Compliance with Applicable or Relevant and Appropriate Requirements Compliance with ARARs addresses whether a remedy complies with all state environmental and public health laws and requirements that apply or are appropriate to the conditions and cleanup options at a specific site. I met, the reasons must be clearly stated and a waiver may be required. With the exception of the no-action alternative (Alternative 1), all the received detailed analysis in the FS would meet the ARARs. The no-actio would not meet ARARs because it would potentially allow continued migrat contaminants from the highly contaminated source area groundwater and so site. C. Long-Term Effectiveness and Permanence Long-term effectiveness and permanence refers to the ability of an alter reliable protection of human health and the environment over time once t have been met. All the alternatives, except the no-action/institutional control alterna would provide long-term effectiveness because they all include removing contamination from source area soil. Alternative 1, the no-action/insti alternative, is not considered permanent or effective in the long term. D. Reduction of Toxicity, Mobility, or Volume of Contaminants Through T Reduction of TMV of contaminants through treatment includes the three pr of the overall performance of an alternative. The 1986 amendments to th Amendments and Reauthorization Act (SARA) emphasize that, whenever possi remedy should be selected that uses a treatment process to permanently r MK01\RPT:00628026.003\site8rod.txt 09/1 of toxicity of contaminants at the site, the spread of contaminants away contamination, and the volume or amount of contamination at the site. All the source control alternatives, except Alternative 1 (the no-action alternative), reduce, to some extent, the TMV of contaminants because th either soil treatment and/or groundwater migration control. E. Short-Term Effectiveness Short-term effectiveness refers to the likelihood of adverse impacts on environment that may be posed during the construction and implementation alternative until cleanup goals are achieved. All of the alternatives retained for detailed analysis in the FS would b term. Because of the potential for release of contaminants through vola excavation activities, however, special engineering precautions would be the potential for contaminant emissions to ensure short-term protection nearby residents during cleanup-related construction activities. Becaus 5 require no large-scale excavations and have less risk of contaminant e alternatives rated higher than Alternatives 6, 7, and 8, which do includ excavation and handling of highly contaminated soil. F. Implementability Implementability refers to the technical and administrative feasibility including the availability of materials and services needed to implement All the alternatives in the detailed analysis are implementable and have successfully at other sites. However, potential difficulties in staging alternatives (Alternatives 6, 7, and 8) could prove to be extremely diff larger quantities of soil and the limited area available to stage the so MK01\RPT:00628026.003\site8rod.txt G. 09/1 Cost The estimated present-worth costs of the alternatives are shown in Table H.

THE SELECTED REMEDY The selected remedy (Alternative 4) is comprehensive in that it provides and management of migration, and it also contributes to the overall atta objectives. The components of this alternative involve: In situ SVE treatment of source area soil contaminated at con exceeding cleanup goals; and treatment of extracted soil vapo of volatilized organics. Construction of an asphaltic concrete cap to minimize rainfal infiltration into the area of SVE treatment. The cap will he moisture content of the soil to be treated by SVE.

The groundwater recovery system will be designed to ca phase contaminant overburden groundwater that is contaminated cleanup goals, and to prevent migration of contaminated groun bedrock water-bearing zone. Construction of an on-site GWTP for long-term treatment of re groundwater. trenches. Treated groundwater will be discharged to subsu Environmental monitoring, such as groundwater sampling, groun elevation monitoring, surface water (including wetlands) moni contamination monitoring, during remedial operations. Long-term environmental monitoring, including groundwater, su and sediment sampling and analysis. Figure 14 is a schematic diagram of the remedial processes employed in A Institutional controls will be implemented in the same manner as for Alt described in the Draft Final Site 8 FS Report (G-611). Site access rest restrictions will remain in-place until sampling and analysis confirmed had eliminated the need for restrictions. Environmental monitoring also implemented as described in Appendix G of the Draft Final Site 8 FS Repo Soil Vagor Extraction of Source Area Soil SVE will be implemented in Site 8 vadose zone soil that has contaminant that exceed cleanup goals. Most of the soil contaminated in excess of c the vicinity of the water table, at approximately 21 to 25 ft BGS, and i floating free-phase product, or is smeared with product constituents as water table fluctuations. Soil cleanup goals also are exceeded in the 0 in areas of Site 8 where contaminants were discharged at the ground surf MK01\RPT:00628026.003\site8rod.txt 09/19/9 <IMG SRC 0194093N> SVE removes volatile contaminants from the subsurface by mechanically dr through the pore spaces of the vadose zone soil. The increased flow of pores enhances volatilization of organic compounds and results in moveme vapors through the soil to extraction vents. The extraction vents are c blower system that draws the contaminant-laden airstream to the surface. typically treated for removal of contaminants prior to discharge to the SVE has several advantages over other available technologies for remedia contaminated soil: SVE is an in situ method that has the potential for treating soil at reasonable costs in comparison to other available tec SVE systems are relatively easy to install and use standard, equipment. This allows for rapid mobilization and implementa remedial actions. SVE systems are generally relatively simple in design. A pilot-scale SVE treatability study was conducted at Site 8 during Apri 1993. The results of the study indicate that SVE will be effective in r zone soil at Site 8 that is contaminated at concentrations that exceed c objectives of the treatability study included: Determination of whether soil deeper than 15 ft BGS has suffi permeability to allow enhanced movement of contaminant-laden the extraction vents. Collection of site-specific data to estimate the rate at whic contaminants from the subsurface. Determination of the types of organic contaminants that SVE w from the subsurface at Site 8. Collection of site-specific data necessary to evaluate the im cost of SVE at Site 8. MK01\RPT:00628026.003\site8rod.txt 09/16/94 Typical SVE systems consist of an array of vents in the area of the unsa zone requiring remediation. These vents are manifolded to blowers or va Valves connected to each pipe provide the flexibility to withdraw air fr at different air flow rates. Extracted soil vapors are normally pretreated prior to passing through b emission control systems. Water droplets and particulate matter are rem decreasing the velocity of the vapor stream in air/water separators. Th air/water separator passes through a filter, blower or vacuum pump, and treatment unit prior to discharge to the atmosphere. The air emissions system will be treated to comply with NHDES regulations. The final design of a full-scale SVE system for Site 8 will be based on conducted at the site. The system will consist of SVE vents; passive ai manifold, blower, and air emission control systems. A low-permeability cap, constructed of asphaltic concrete, will be place be treated by SVE, excluding the area within the Newington Town Forest. of the capping scenario using a numerical model calibrated to conditions that the cap will result in a lowering of the water table in the soil to approximately 12 to 18 inches. This will allow the SVE system to provid in the smear zone that would have otherwise been below the water table. generated by the asphalt cap will be controlled by detention basins, swa surface drainage structures as shown in Figure 15. Operational monitoring of the SVE system will include monthly sampling a vapor extracted from the subsurface by the SVE system. The relative con VOCs in the vapor will be measured with a photoionization detector (e.g. ionization detector (eg., OVA) and recorded. If the concentration of VO decreases to nondetectable levels, or if the concentration stabilizes at soil samples in the contaminated areas will be collected and analyzed fo MK01\RPT:00628026.003\site8rod.txt 09/19/9 <IMG SRC 0194093O> sample analytical results indicate that cleanup goals have been achieved remedial action to address soil contamination will be considered complet concentrations in the soil are not below cleanup goals, additional remed modification of the SVE system to enhance treatment will be considered. the soil cleanup goals will be achieved within 5 years based on the esti contamination and the estimated vapor extraction rates.

The Air Force will verify through the submittal of evaluations and 5-year reviews to EPA and NHDES that the cleanup of the bedrock zones, is progressing. If the data indicate that the cleanup of not progressing, then the Air Force will implement a bedrock groundwater Groundwater Treatment Groundwater will be treated by a new GWTP to be constructed at Site 8. possible, the new GWTP will use equipment from the pilot GWTP.

Methodology for Cleanup Level Determination Cleanup levels have been selected for each medium of concern at Site 8. have been established for chemicals of concern identified in the risk as the Draft Final Site 8 RI Report (G-577) and for contaminants detected a ARARs, risk-based concentrations, or leaching-based concentrations. The approach used to determine risk-based concentrations is consistent w used to evaluate both human health and ecological risks in the risk asse the Draft Final Site 8 RI Report (G-577). This approach is presented in Generation of Baseline Risk Assessments for Pease Air Force Base (G-568) Risk-based concentrations were derived for the chemicals of concern in s groundwater based on the RME (current or future) for the medium. The ch concern include those substances that were identified as chemicals of co assessment section of the Draft Final Site 8 RI Report (G-577). In addi concentrations were derived for a few chemicals that were not selected a concern in the risk assessment, but whose maximum reported concentration or more ARAR. Risk-based concentrations were derived for each noncarcinogenic chemical based on a goal of a hazard index of 1. For each carcinogenic chemical, were derived based on a goal of 10-6 (1-in-1 million) lifetime cancer ri exceptions. Some chemicals, although categorized by EPA as carcinogens, considered to be carcinogenic through all exposure routes. For example, including cadmium, chromium VI, and nickel, are not classified as carcin oral exposure route. Therefore, in deriving risk-based concentrations f if a carcinogenic chemical was not considered to be carcinogenic through MK01\RPT:00628026.003\site8rod.txt 09/19/ exposure routes, the risk-based concentration for the chemical was based of 1 (i.e., noncarcinogenic risk). Ecological risk-based concentrations were calculated for chemicals of co (0 to 2 ft BGS) at Site 8. These concentrations were based on the maxim ecological receptor to ensure that the concentrations are protective of that can be evaluated. Ecological risk-based concentrations for surface were evaluated using AWQC and NOAA ERÄÄL values, respectively. Cleanup levels were selected after comparing maximum contaminant concent detected for each chemical of concern in each medium with appropriate ch ARARs, human health risk-based concentrations, and, if applicable, ecolo concentrations. In general, where ARARs were available and deemed appropriate, the ARARs selected as cleanup levels. Where ARARs were not available, or if the b ARAR was established was not consistent with Site 8 exposure scenarios, concentration was selected as the cleanup goal. When ARARs were selecte goal, a human health risk was calculated for the ARAR concentration.

The selected remedy also satisfies the st for treatment that permanently and significantly reduces the TMV of haza as a principal element. Additionly, the selected remedy uses alternativ technologies or resource recovery technologies to the maximum extent pra A. Protection of Human Health and the Environment The remedy at the site will permanently reduce the risks posed to human environment by eliminating, reducing, or controlling exposures to human receptors through treatment and by engineering controls. Specifically, employs in situ SVE of source area soil to remediate soil contaminated a This will involve extraction of VOCs from the soil. destruction of VOCs.

The current risks associated with ingestion and soil requiring remediation currently fall within the target range of 10soil contaminants into the groundwater, however, may result in exceedanc cleanup goals, which could result in increased risks associated with the exposure pathways. EPA regulates maximum risk at hazardous waste sites acceptable risk level within this range. Treating the soil by in situ S to within the range of acceptable exposure levels and also reduce leachi into the groundwater to within acceptable levels. By capping the site t into the area of soil vapor treatment, the risks of exposure through dir further reduced. The current risks posed by groundwater exceed EPA's ta range of 10-6 to 10-4.

Of those alternatives that are p health and the environment and comply with ARARs, EPA and NHDES have det that the selected remedy provides the best balance of tradeoffs in terms effectiveness and permanence, reduction in TMV of contaminants through t term effectiveness, implementability, and cost, while considering the st treatment as a principal element and considering state and community acc The selected remedy does offer as relatively high a degree of long-term permanence as do the excavation alternatives, and it will significantly hazards posed by the contaminated soil through SVE of the VOCs and will hazards posed by groundwater by extraction and treatment. The hazard po phase product would be removed by recovery and off-base disposal of the product. The selected remedy treats the principal threats posed by the soil, achi VOCs reductions. The implementability of the selected remedy is compara nontreatment alternatives and significantly better than the excavation o remedy also is the least costly in situ option and is less expensive tha The selection of this remedy is consistent with program expectations tha toxic and mobile wastes are a priority for treatment and that treatment to ensure the long-term effectiveness of a remedy. Since all in situ an options are reasonably comparable with respect to long-term effectivenes and mobility reductions achieved, the major tradeoffs that provide the b decision are short-term effectiveness, implementability, and cost.

DOCUMENTATION OF SIGNIFICANT CHANGES The Air Force presented a Proposed Plan (Alternative 4) for remediation January 1994 (G-679). The components of the preferred alternative inclu In situ SVE of source area soil. Construction of a cap. Construction of groundwater/free-phase product recovery trenc contingency. Recovery and off-base disposal of free-phase product. Management of migration in overburden groundwater. Management of migration in bedrock groundwater as a contingen Construction of an on-site GWTP for treatment of recovered gr Environmental monitoring during remedial action. Long-term monitoring. There have been no significant changes in the selected alternative since Draft Final Site 8 FS Report (G-611) and Proposed Plan (G-679). It should be noted that several regulations have been updated and some a enforceable, where they were not previously. MK01\RPT:00628026.003\site8rod.txt this ROD, have been added to Appendix A.

Based upon its review of the S and acting as agent for the State of New Hampshire, the Department concu remedial action decision, selected under CERCLA, for Site 8. The Site 8 ROD was developed in accordance with the Comprehensive Environmental Response, Compensation, and Liability Act of 1986 (CERCLA) outlines source control actions and management of migration actions to b by the Air Force in order to remedy the threat to human health and the e by contamination at Site 8. Prior to Pease Air Force Base becoming a Superfund site, and as a p "Pease Federal Facility Agreement Under CERCLA Section 120" (Pease FFA), Department has been actively involved in the oversight of the Air Force' response activities at Site 8. The approach to site remediation, as out ROD, is generally consistent with the approach the Department would requ Remedial Action Plan for similar sites in the State of New Hampshire, re Superfund status.

The preferred alternative involves soil and floating f mixture cleanup at the source area and groundwater containment and treat The subsections that follow describe the background on community involve 8 activities and the Air Force's response to both written and verbal com during the Site 8 Proposed Plan Public Comment Period of 26 January to 1 BACKGROUND ON COMMUNITY INVOLVEMENT Prior to the start of the public comment period for Site 8, the Air Forc that summarized the contents of the Site 8 Proposed Plan. Presentations work being conducted and results of the work at Site 8 area were made to Technical Review Committee (TRC). Additionally, the content of the Site was provided to the TRC members in draft format and discussed with the T in November 1993. Input from the TRC members was taken into account in final Site 8 Proposed Plan. Announcements were mailed to all individual AFB Community Relations Plan mailing list in January 1994 prior to the b public comment period. Additionally, press releases were issued to the the beginning of the public comment period. Announcements were publishe newspapers prior to the public hearing date of 1 March 1994. The origin scheduled for 9 February 1994, had to be postponed due to inclement weat cancellation were sent to all media and interested parties. The resched date and public comment period extension announcements were published in newspapers. It is noted that the public comment period and public heari concurrent with Zone 5. Proposed remedial actions for Site 8 and Zone 5 equally to the public. SUMMARY OF COMMENTS RECEIVED DURING THE COMMENT PERIOD AND AIR FORCE RESPONSES During the public comment period, three sets of written comments were re individuals provided comments at the public hearing held on 1 March 1994 received during the comment period are summarized as follows, along with response to each comment. A copy of the public hearing transcript is av along with the written comments received on the Site 8 Proposed Plan, at Information Repository located at 61 International Drive, Building 43, a Hampshire. MK01\RPT:00628026.003\site8rod.apc 1. 2. 3. 4. 5. Comment (written): There should be mention of a written Section 1 110 process which would address the preservati forest. Response: As part of the remedial action evaluation proc Force has to evaluate all Applicable or Releva Appropriate Requirements, of which the Nationa Preservation is one. Reference to this Act is 8 Feasibility Study (FS) and will be reference Record of Decision (ROD). Comment (written): In all of the maps for both publications, the Forest designation is not correct nor outlined Response: The designation and location of the Newington will be clearly shown in the figures included Site 8 RODs, as will Site 11, the Field Mainte Equipment Cleaning Site. Comment (written): Proposed Plan 3 (sic) does not include the spe the site is on the National Register of Histor Response: Reference will be made in the Site History sec 8 ROD that a portion of Site 8 lies within the Town Forest. A brief discussion of the histor Forest will be included. Comment (written): Why is the ROD not submitted to SHPO (NHDHR) f approval? Response: SHPO does not have approval authority for envi remedial action RODs; this authority rests wit Comment (written): Why is not the National Register designation this definitely affects the management of the be a consideration. Response: 6. 09/14/ Reference to the fact that the Newington Town Fore on the National Register of Historic Places will b the Site 8 ROD. See response to comment no. 4. Comment (written): How do you expect to keep the NHDHR advised o next 30 years of your cleanup operations at Zone 5 Response: The Air Force believes the question is intended toward the Site 8 action because that is the only would involve the NHDHR. The Air Force and NHDHR MK01\RPT:00628026.003\site8rod.apc in the process of developing a Memorandum of (MOA) governing the Site 8 remedial activities occur within the boundaries of the Newington T One aspect of this MOA will be a provision for these activities.

Comment (written): Is there a written management plan about the d (now and future) to the Town Forest? Response: As stated in response to comment no. 6, th NHDHR are in the process of developing an MOA govern the Site 8 remedial action work within of the Newington Town Forest. On 28 February Force met with representatives of the NHDHR, a representatives from the Newington Selectmen's review the proposed activities for Site 8 and potential impact and methods to minimize them. of this discussion are being used to develop t Town of Newington will be a concurring party t Comment (written): The Newington Historic District Commission wis informed of the remedial operation and hopes t Newington Forest Management Plan recommendatio a consideration as you implement your remediat Response: The Air Force has established a Technical Rev (TRC) that meets monthly to review and discuss environmental activities at Pease AFB, includi action activities at Site 8. The Town of Newi Selectmen's Office has a representative on the provide the up-to-date status of the Site 8 ac various Newington Boards and Commissions. For management operation, consistent with the hist the Newington Town Forest, is one of the facto in the development of the MOA referenced in re comment no. 6. Comment (written): As for the matter at hand this evening, we co proposed remediation of Site 8, with the unde every effort will be made to avoid adverse im Newington Town Forest, the oldest such forest States, a status that was duly recognized by the U MK01\RPT:00628026.003\site8rod.apc 09/14/94 of the Interior when the forest was listed on Register of Historic Places. Response: 10. Comment (written): It is the recommendation to cap rather than re contaminated soil that I strongly oppose. I belie removal of contaminated soil from the surface to t the high water table is a justified despite the co capping is not an acceptable alternative. Response: 11. The Air Force intends to fully clean up the s source area at Site 8, meeting the cleanup goals s the Proposed Plan. The remedial technology select Air Force to accomplish this cleanup is soil vapor (SVE). SVE will remove the contaminants within th without having to excavate the soil. This process to take approximately 5 years to complete. The ca commentor refers to is only a component of the SVE The cap makes the SVE process more efficient. Sev excavation options were considered in the FS; howe the nine required criteria to evaluate each altern Force determined that the SVE was overall a better technology to apply at Site 8 for soil remediation excavation and on-site treatment of soil. Comment (written): On Figure 1, the General Site Map for Site 8, AF Preferred Alternative Site Plan, the property b for the Cross lot do not correctly reflect the cur maps and site plan for my lot on file in the Rocki County records. This correction is important as i that the plume of contamination is across my land been directly impacted. For your final report att please adjust the lines as indicated on the c Response: 12. The Air Force is taking into account the pote Site 8 actions might have on the Newington Town Fo The Air Force is working with the NHDHR to develop MOA governing the work activities in the Town Fore In development of the MOA, strong consideration wi given to specifying methods of work execution to m negative effects to the Town Forest area. The general site map for Site 8 and other app will be correct in future documents, including the to correctly show the Cross property boundary. Comment (written): The last sentence on Page 4-1 states 262 tons soil were removed. What was the cost to treat this soi MK01\RPT:00628026.003\site8rod.apc 09/14/94 what was done to it? Does it become much chea done on a large scale? Response: The 262 tons, or 175 cubic yards (yd3), of co were transported to a secure landfill in Main Environmental Recovery Facilities, Inc., of H February 1990. The cost of this disposal pro approximately $52,000. The cost of disposal today and on a larger scale would not be nece cheaper (unit price). It would potentially b because of new regulations that have been put specify how, where, and what pretreatment mus before contaminated items can be disposed of. this past disposal method is an example of ju contaminated media from point A to point B wi reduction of contaminant toxicity or volume. preferred EPA objective for remedial actions contaminated toxicity, mobility, and volume t actions, i.e., treament inplace rather than m contamination to another location. 13. Comment (written): Page 4-2, Para 4.2.1: How many tons of soil a within 500 feet horizontally to a depth of 30 feet? How rapidly does the level of contamination decrease with d Can you remove a good portion of the problem with remov only the top "X" many feet? For example, if you remove down to the top of the water table level, how many feet it be? Response: 14. The levels of contamination in the soil actua depth, with the highest level of contamination being in smear zone at the water table. This smear zone is approximately 7 feet wide (vertical) and occurs at a de approximately 25 feet below ground surface (ft BGS). T total volume of soil that would have to be removed to excavate the contaminated soil in the smear zone is est at 175,000 yd3, of which approximately 59,000 yd3 of so actually contaminated. Comment (written): Page 4-2, Para 4.2.2: Are the contaminants o Brook not site related because they are a different typ found at Site 8? I could not locate Knights Brook in F 1. Did I overlook it? Since you refer to it in the re would help to label it in Figure 1. Response: The results of the Site 8 Remedial Investigat that groundwater from the site discharges to Pickering MK01\RPT:00628026.003\site8rod.apc 09/19/94 The surface water and sediment sampling locations as part of the Site 8 Remedial Investigation detec contaminants in Pickering Brook. The contaminants in Pickering Brook are not considered to be Site 8 because of the limited ability of the contaminants from Site 8 to Pickering Brook. However, sin has been owned by the Air Force for the past 40 ye contamination in Pickering Brook is most likely th Air Force activities. Regardless of the source of contamination, the levels of these contaminants de Pickering Brook were either below regulatory crite exceeded criteria at a low frequency. These excee occurred infrequently during sampling rounds at on two of the sampling locations along Pickering Broo results of the Site 8 risk assessment revealed tha to human and ecological receptors were acceptable consequently, do not require remediation. In addi Force continues to monitor surface water and sedim at Pease AFB and will be monitoring surface water Pickering and Knights Brooks as part of the remedi for Site 8. Labeling of Knights Brook was inadver off of Figure 1. Knights Brook begins in the wetl shown in the Frink Trust property in Figure 1. 15. Comment (written): Page 5-1: Human Health Risk: None posed. D that there should be no restrictions on use of the nature trail where hikers would sit on or touch th Ecological Risk: Risks posed to mouse and sparrow is the risk to animals that may catch and eat thos risk? Response: True, for all media except for groundwater. surface use of the area would be unrestricted. Fo nonresidential use, risks were evaluated assuming industrial/commercial use of the property in the v former burn areas. This future use assumption is with the current zoning for this area. Based on t assumption, risks were evaluated for a maintenance who is the most likely maximally exposed individua potential for health risks was below EPA's benchma concern.

Comment (written): Page 7-3, 2nd Bullet: The statement that the in lowering the water table is incorrect unless the cap water rather than just shielding it. Doesn't the water run to the sides and flow horizontally under to the sam Isn't the groundwater recovery system based on this fre horizontal flow? Would you consider rephrasing your statement to say the cap in the cleared area has a mini disturbance to the remaining trees although it prevents Town Forest from reclaiming the FDTA cleared area by re growth for 30 years? Response: The cap will be graded such that the water interce cap is drained away from the site. This will fluctuations in the water table as the Site 8 former bu represent a groundwater recharge area. The Newing Forest area, as listed on the National Register of Hist Places, does not include the former burn areas of Site boundary for the Town Forest is the stone wall that lie of the Site 8 fire training area. Future use of the pr encompassed by the Site 8 fire training area will be at option of the new property owner once transfer occurs. Currently, a majority of the Site 8 fire training area the Airport District at the Pease International Tradepo surrounding area is zoned airport industrial by the Tow Newington. The Air Force is unaware of any plan by the reuse organization(s) for Pease to expand the Town Fore into the Site 8 fire training area. The groundwater re system is based on horizontal flow, the cap helps stabi vertical components of the groundwater units. A statem MK01\RPT:00628026.003\site8rod.apc 09/19/94 will be made in the Site 8 ROD that the area will have a minimal effect on the adjacent To 19. Comment (written): Response: 20. 21.

Please note this show the location of the Town Forest areas in ROD. As for the recovery trenches, first the established if it is determined that the recov needed, then a location must be determined. I recovery trenches need to be located in the To the Air Force will have to coordinate this act accordance with the MOA governing work in the area. As the Town of Newington will be a conc this MOA, its input to the location of the tre solicited. Comment (written): Response: Page 7-3: How deep would the recovery trench locations shown in Figure 3, how would you pre damage to the existing Town Forest? To what e Newington have a voice in whether and where th will be dug? Page 7-3: Is there a formal report by which notified of progress in attaining the overburd Will these only be changed with Newington's co The cleanup goals will be specified in the Site 8 goals can only be changed through revision to, or modif of, the ROD. This would require EPA and NHDES concurrence and public input before the decision proces completed. The Newington representative on the TRC wil kept apprised of the status of the remedial action at S Additionally, the reoccurring, 5-year review process wi become public information. Comment (written): Page 7-3, Last Bullet: Why is worker protecti needed if the soil is safe for human contact as stated 5-1? How are we sure that funds will continue to be av for the monitoring and reporting? Response: The risk assessment for human health was based on maintenance worker who is exposed to soil in the 0- to 0- to 15-foot levels year-round on a long-term basis. assumes that no major disturbance of the soil occurs. Th construction work during installation of the SVE system w MK01\RPT:00628026.003\site8rod.apc 09/16/94 result in soil below 15 feet, where the highe exist, being brought to the surface. This could r worker exposure to both soil themselves and vapors emanate from the soil and to large quantities of s be generated during construction activities. The the construction worker is for the potential risk relatively short-term exposure to higher doses of The risks can be very different from those posed t maintenance worker as a result of long-term exposu doses. Therefore, worker protection monitoring ne put into place during the construction phase. It of the Air Force to fully fund this remedial actio future fund distributions are really a function of Congress authorizes to the Air Force as part of DO process. The future congressional actions are out control of the Air Force. 22. Comment (written): Please send me the cleanup goal (æg/kg) for b, DCA; and TCE.

And one of the though in the past is, even when I built my house, the ba they would give me a mortgage at first was re of things about contamination on the soil and been done in the past before they would even mortgage. And so if there are easements that deed for certain monitoring of that property, flag, saying to any mortgage company, uh-huh, here? Now I know the land right now is owned Base, but there is a potential that could bec public land in the future. Response: 29. Comment (verbal): The area of Site 8 that would require deed restric be called a Groundwater Management Zone (GMZ) zone boundary line is where the groundwater q from unacceptable to acceptable, and usually zone. For Site 8, the GMZ would mostly be on Force property, with a small portion being on Town property, Town Forest area behind the st adjacent to Pease AFB boundary. If the Air F transfer the property to a private entity in covenant would be in the deed that states the could not be used, ensure rights of access to Air Force, and state Air Force responsibility remedial action at the site. These actions w that the responsibility for remedial action a to the Air Force and would insulate the new o liabilities from past Air Force activities. The next comment I have related to...I've loo alternatives and, you know, tried to understa mean by each one of them. But nowhere have I figure out that the efficiency of this soil v Somewhere along the line it was determined th efficient enough process to remove this conta period of 30 years, and I couldn't see anythi me how that related to excavation. So this w you can remove this contamination by these hy I guess it's pumping water, whatnot, doesn't Will that be ultimately as efficient as takin it differently? Is it a time difference? Wh years? MK01\RPT:00628026.003\site8rod.apc Response: 09/19/94 There are two efficiency issues: one of the various source area (burn pit) actions, in th SVE process versus excavation, and the other of the hydraulic controls (groundwater pump a Regardless of which source area action is imp 8, pumping and treatment of the groundwater w The time it will take to remediate the ground acceptable levels would not likely be signifi selection of one source area action over anot difference between the various source area ac years), as compared to the estimated 30 years groundwater treatment, is not that great.

Section 5 of the D 8 FS Report contains more detailed informatio implementability of the various alternatives Site 8. 30. Comment (verbal): The third point that I had is, I've looked at alternatives, I can't really figure out who d of these to choose. It sound like the Air Ba several of them and decided that they would l what is SC-3, MM2. And then some of the othe said, you know, we're withholding our accepta MK01\RPT:00628026.003\site8rod.apc Response: 09/19/94 The Air Force identifies the alternative that most appropriate for the site to EPA and NHDES. T done in the draft Proposed Plan submitted to EPA a NHDES under the provisions of the Pease AFB Federa Facility Agreement. One aspect of the review of t proposed plan by EPA and NHDES is acknowledgment o acceptance of the alternative selected by the Air acceptance of the alternative cannot be made, the EPA, and/or NHDES meet to resolve any outstanding and come to an agreement on the most appropriate alternative. This agreed upon preferred alternati the other alternatives evaluated in the FS are pre public in the final Proposed Plan. What was meant statement that other boards (NHDES) were withholdi acceptance is that final acceptance was being with satisfactory completion of the public comment proc public comment process, especially the input recei the public, plays an important role in the remedia decisionmaking process. The final decision really made until public input is received and considered 31. Comment (verbal): It seems to me that as an absolute minimum, yo to, from the very beginning, accept MM-3 as yo criteria. And the reason I say that is that y there is contamination in the bedrock water. accept that as the minimum alternative right n figure out at what point in the future in thes plans that you would then go back and decide t There's nothing that says there would be publi that, and it's just some undetermined date in I don't feel comfortable with. If it was mand of the alternative that gets adopted, if it tu a problem, you just don't have to do it, but a put into the proposal to begin with that is so needs to be addressed. Response: The Air Force understands the commentor's conc contamination in the bedrock water-bearing zon equally concerned. The contamination at Site from the former burn areas and enters the over bearing zone. Migration of contamination in t flows in a northerly direction, and, at a poin 8 former burn areas, some portion of the conta overburden flows into the bedrock water-bearin Air Force, based on data developed for Site 8, the migration of contaminated water from the o the bedrock can be controlled by hydraulic con MK01\RPT:00628026.003\site8rod.apc 09/19/9 implemented in the overburden. Contamination bedrock water-bearing zone would then attenua As part of the design process, the Air Force evaluate the migration control process to ens really work. Additionally, a perform standar measuring stick, will be developed to measure effectiveness of the migration control implemented in t overburden. The development of the performance standar will be done as part of the design process, which will EPA and NHDES review and require their concurrence before the design can become final. A timeline would a part of the performance standard that would specify whe measurements would be taken and at what point a determination would be made to implement pumping of the bedrock water-bearing zone if it were determined to be necessary. Public involvement is available at the pres through the Technical Review Committee. If it is found necessary or appropriate, additional public meetings co held. In addition, the EPA regulatory process requires formal review of the remediation process at 5-year inte If performance of the remedial action is not meeting th requirements of the ROD, the remedial process could be revised, as necessary. 32. Comment (verbal): Now the next comment I have relates to, again, concept of what is your next alternative, this SC4-MM3, actually involves excavation and biological treatment. I can't tell from this why that wouldn't be a preferred alternative. I've looked at some of your charts, A, B, all of the criteria that you judged, and it seems that, I can tell, that's just based on cost. And so it gets question, again, is the water pumping efficient or is t efficient, and how was that decision made? Because rig it's not possible to tell. It does seem to me that the treatment of excavated soil is probably a bit of an ove I still have real strong questions about why there about Alternative 6 that disqualifies i me that Alternative 5 has to be the bare mini Alternative 6 still has to be addressed. Response: The presentation made in Table 3 of the Site 8 Proposed Plan, using the A, B, C designation is an extreme oversimplification of the detailed analysis evalua performed in the FS. The need to pump the groundw common to all the remedial actions except for Alte no action. The major difference between the vario alternatives is how the contamination in the soil MK01\RPT:00628026.003\site8rod.apc 09/19/94 with, either treatment in-place or by excavation a on-site. The major factor that distinguishes treatment methods between one another is the implement the action. In this case, the exca is much more difficult to implement than is t process. An evaluation of the efficiencies of the treatment processes is provided in response t 29. Additionally, Section 5 of the Draft Fin much more detailed information on the evaluat various alternatives, including soil treatmen 33. Comment (verbal): Now the last comment I wanted to make relates your drawing of where you put your MCL line. being very careful to say that right now that Pease boundary. Now I certainly would acknow Air Base has been excellent in testing our sp and in telling us what the levels of contamin in the spring. It's certainly true that thos what the health regulations, the whatever min that you're using, but it's also very dear th decreased after 5 years of treatment over on It's not going down, it's not going up, but i coming from the bedrock water that's going, I underground and coming up in springs, which t it's fairly arbitrary to, at this point in ti water and the management of that is not neces point of view, it's absolutely necessary.
