Executive Summary
This Class A-3 Response Action Outcome Statement (RAO Statement) has been
prepared by ARCADIS for Solutia Inc., for a Tier II site identified as the Former Vinyl
Chloride Gas Holder Area located within the Indian Orchard Plant at 730 Worcester
Street, in Hampden County, Springfield, Massachusetts, Release Tracking Number
(RTN) 1-11901 (site). This RAO Statement documents that a condition of No
Significant Risk and other requirements associated with a Class A-3 RAO has been
achieved for the site in accordance with the Massachusetts Contingency Plan (310
Code of Massachusetts Regulation [CMR] 40.1000).
A Class A-3 RAO is applicable to the site as described in this RAO Statement for the
following reasons:
•
Response actions were conducted and a condition of No Significant Risk has been
achieved; no additional Phase V operation, maintenance and/or monitoring
activities are required.
•
Constituents in soil have been reduced to below UCLs. As a result, groundwater
concentrations and extent have been reduced. The source to soil (i.e. PVC
manufacturing) has been eliminated. For these reasons the source is under
control.
•
An MCP -defined Permanent Solution has been achieved.
•
Constituents in the environment are not reduced to background; the feasibility of
achieving background was evaluated and was found impractical under current
conditions.
•
One or more Activity and Use Limitations (AULs) are applied to maintain a
condition of No Significant Risk.
A copy of the RAO Statement BWSC (Bureau of Waste Site Cleanup) Form 104 is
included in Appendix A of this RAO Statement.

1. Introduction
On behalf of Solutia Inc. (Solutia), ARCADIS has prepared this Class A-3 Response
Action Outcome Statement (RAO Statement) to document the completion of an RAO
for the Former Vinyl Chloride Gas Holder Area (FGHA) located within the Indian
Orchard Plant, an active manufacturing facility at 730 Worcester Street, Hampden
County, Springfield, Massachusetts (site). The site is identified as Release Tracking
Number (RTN) 1-11901 with the Massachusetts Department of Environmental
Protection (MassDEP). The Bureau of Waste Site Cleanup (BWSC) Form 104 is
included in Appendix A of this RAO Statement. A Representativeness Evaluation and
Data Usability Assessment (REDUA) and an Activity and Use Limitation (AUL) to
support the RAO are provided in Appendices B and C, respectively.
1.1 Property and Site Location
The FGHA is a small less than 0.1 acre Tier II-classified site located on eastern portion
of the Solutia Indian Orchard Plant (Figure 1). The site boundaries of the FGHA are
provided in Figure 2 of Appendix B and in the AUL in Attachment C-1 of Appendix C.
The Indian Orchard Plant is an active manufacturing facility and will remain so for the
foreseeable future.
The 170 acres of land owned by Solutia is zoned Industrial according to a city of
Springfield Planning Board, Zoning Ordinance (dated March 11, 1996) and has been
used for industrial purposes since at least 1904. There are no outstanding proposed
zoning changes. Of the 6-acre area surrounding the FGHA, which is within the 170acre Indian Orchard Plant, 50 percent is currently used for process equipment,
manufacturing or temporary raw materials storage. The remainder of the area
surrounding the FGHA is used for parking, manufactured goods, and employee and
contractor transportation (pedestrian, vehicle and railcar) corridors within the Solutia
Property. Although the buildings in the vicinity of the FGHA are used to house process
equipment and are not used by 8-hour workers, general workers periodically perform
process equipment operation and maintenance activities both indoors and outdoors.
The Indian Orchard Plant as a whole is secured by fencing, and entrance gates are
maintained 24 hours per day by security guards. Transportation corridors consist of
roads and railroads on which Solutia personnel move equipment or materials within the
site. One railroad track with locked gates allows for railroad employee and vender
access and egress through the Solutia properties.

On the Solutia Property, there are three gated entrances that allow for access and
egress for Solutia employees. However, no routes through the Indian Orchard Plant
Property are accessible to the general public. These gates and access routes are
secured 24 hours per day and are manned by guards to prevent unauthorized
entrance. A fence surrounds the entire Indian Orchard Plant boundary, prohibiting
access by the general public. In addition, a fence separates the Solutia portions of the
Indian Orchard Plant from the portion of the property owned and operated by others.
An individual is allowed to enter the Indian Orchard Plant through a secured gate only
after passing an annual Solutia plant-specific health and safety training exam, and
when escorted by an authorized Solutia employee.
The surrounding off-site land use in the vicinity of the FHGA is primarily a mixture of
commercial/industrial/ forested.
There are no known groundwater users or water-supply zones within a 1.2-mile radius
of the Indian Orchard Plant (ARCADIS BBL, 2007). The Indian Orchard Plant and the
surrounding properties use the city of Springfield public water supply (pers. com., Kate
Brown, Springfield Public Health Office, City of Chicopee Health Department, March 1,
1996). Furthermore, the nearest aquifer that could potentially be productive is located
1.2 miles hydraulically upgradient of the Indian Orchard Plant.
The property is not within a zone classified as a “potentially productive aquifer” (PPA)
(Blasland, Bouck & Lee, Inc. [BBL], 1996; ARCADIS BBL, 2007). In addition, based on
review of available literature, the potential well yield from the Chicopee River drainage
basin would be less than 100 gallons per minute, locally. Installation of new watersupply wells is controlled; new private wells are permitted through the local health
department and municipal water-supply wells are permitted through the MassDEP. If
this property was located within a PPA, the criteria for classification as a nonpotential
drinking-water source area (NPDWSA) per policy WSC-97-701 would apply because
the following criteria are met:
•
•
The plant encompasses an area of greater than 100 acres.
This 100 plus acres is used for industry and/or electrical power.
The city of Springfield obtain their water from a municipal water supply system
originating from Cobble Mountain Reservoir, Quabbin Reservoir or Springfield
Reservoir, at distances ranging from 6 to 20 miles hydraulically upgradient of the site.
The GW-1 criteria do not apply to this site because water is supplied by the city of

Springfield; and groundwater is not used for drinking water, has little potential for future
use as drinking water due to low yield and would meet the MADEP NPDWSA
designation.
1.2 Background and Release Description
The FGHA is a Tier II-classified site (as of June 1998) located on the eastern portion of
the Solutia Indian Orchard Plant Property near a former aboveground process vessel
(“gas holder”) that recycled vinyl chloride (VC; see Figure 2 of Appendix B). VC was
used in the gas holder tank in the southern portion of the site at former Building 85
during the manufacturing of polyvinyl chloride (PVC) from 1946 to 1975. Volatile
organic compounds (VOCs), consisting primarily of VC, exist in a layer of fine, white
granular material (partially polymerized PVC) approximately 5 to 6 feet below ground
surface (bgs) in a small 3,000-square-foot (less than 0.1 acre) area. The source of the
VC detected in soil and groundwater is likely the VC vapor condensation holder tank
vessel. This holder tank contained residual and partially polymerized PVC that may
have been emptied onto the ground from the gas holder and then buried with soil when
the area was regraded. Since the manufacturing of PVC was terminated, a continued
source of VC to soil has been eliminated.
Prior to remediation activities, white material in soil was discovered in the subsurface
(which was confirmed to be off-specification, standard-grade PVC or partially
polymerized PVC) and initially exhibited concentrations of VC up to approximately 450
milligrams per kilogram (mg/kg). This initial finding exceeded the Massachusetts
Contingency Plan (MCP) upper concentration limits (UCLs). Lesser concentrations of
trichloroethene, 1,2-dichloroethene and 1,2-dichloroethane were detected above MCP
reportable concentrations (RCs), but below UCLs. As such, on June 30, 1997, a 120day release notification was reported to MADEP.
Groundwater flow direction at the FGHA is toward the southwest, as presented in the
MCP Phase II Comprehensive Site Assessment Report for RTNs 1-10793, 1-10868, 110869, 1-11692, 1-11693, 1-11694, and 1-11901 Investigation Areas (MCP Phase II
CSA Report) (BBL, 2000a) and subsequent status reports prepared for Solutia
(BBLES, 2001b, 2002a, 2002b, 2003a, BBL 2003b, BBLES 2004a and 2004b). The
dissolved VC plume in groundwater has been defined and is within the Solutia Property
boundaries (BBL, 2000a; BBLES, 2001a; BBLES, 2001b, BBLES, 2006b). The plume
does not extend to the Chicopee River, which is located more than 700 feet
hydraulically downgradient from the edge of the plume (BBLES, 2000a; BBL, 2000c;
BBLES, 2001a).

2. Response Action Summary
2.1 Compliance Status
The site was listed as a Tier II site following a 120-day release notification following the
discovery of VC in soils above RCs in March 1997. Consistent with Response Action
Deadlines and Requirements for Tier II disposal sites, specified in the MCP 310 CMR
40.0560, a Phase I Initial Site Investigation was completed within one year of
notification and a Phase II CSA with Method 3 Risk Characterization was completed in
February 2000 (within 2 years of the effective date of the Tier Classification). In-situ
remediation of soils was initiated under the Release Abatement Measure (RAM) dated
April 2000. The Phase III or RAO was originally due on July 7, 2000 based on the Tier
classification date; however, an extension was requested to allow time to achieve the
objectives of the RAM and provide data to support remedy selection for the Phase III.
As such, Tier II extensions were requested to allow for continued RAM activities. On
August 14, 2003, the Phase III Remedial Action Plan and the Phase IV Remedy
Implementation Plan were prepared for the FGHA (BBL, 2003b). A Phase V Remedy
Operation Status was achieved by August 2004.

2.2
Response Action Descriptions
ARCADIS completed an investigation of source, nature and extent in support of the risk
characterization. A total of 159 groundwater samples and 94 soil samples were
collected and analyzed for VOCs in and around the FGHA, as presented in the REDUA
(Appendix B). The selection of soil samples was based on 122 soil borings and the
collection of 389 field-screened soil samples, as presented in Section 3.3.2 of
Appendix B.
Remedial activities involved the injection of a chemical oxidant additive (sodium
permanganate [NaMnO4]), according to the following documents:
•
MCP Release Abatement Measure Plan Letter for the Former Gas Holder Area,
RTN 1-11901 (RAM Plan) (BBL, 2000b)
•

Sodium permanganate was injected to treat the off-specification PVC found to contain
VC at concentrations above MassDEP soil UCLs. Although the VC was leaching to
groundwater at concentrations below GW-3 standards, the specific objectives of the
MCP Phase V injection and monitoring activities were to:
•
degrade the VC average concentration in soil below UCLs as part of an MCP
Permanent Solution RAO within the source-area materials
•
reduce the potential for VC to leach to groundwater
•
demonstrate the adequacy of natural attenuation (NA) mechanisms in groundwater
in support of a monitored NA remedy (MNA) downgradient of the source area
Between May 2000 and November, 2004, nearly 10,000 gallons of 3 to 4 percent
NaMnO4 solution was injected into the subsurface within the target zone to treat and
reduce VC concentrations in soil in-situ. Injection of oxidant (NaMnO4) was dispersed
throughout the approximately 3,000-square-foot target area through 110 injection
points (Figure 2 of Appendix B).
2.3 Method 3 Risk Characterization
The MCP Phase II CSA Report (BBL, 2000a) was completed to comprehensively assess the
site with respect to:
•
source, nature and extent of constituents detected in the soil and groundwater or
affected media
•
potential receptors and exposure pathways
•
risks to health, safety, public welfare and the environment per 310 CMR 40.0900 in
conformance with RAPS 310 CMR 40.0900
The MCP Phase II CSA Report was prepared to meet the requirements of 310 CMR 40.0800
and 40.0900 of the MCP (October 31, 1997, amended October 29, 1999), with various
updates including the MassDEP’s Preservation Techniques for Volatile Organic Compound
(VOC) Soil Sample Analyses, WSC #99-415 (March 8, 1999).
To minimize uncertainty, the data included in the risk characterization were validated
and met the MCP Response Action Performance Standards, 310 CMR 40.0191

(Massachusetts Department of Environmental Protection (MADEP [now MassDEP],
1997), as well as current presumptive certainty requirements (Appendix B).
Additionally, although all of the data collected as part of the ongoing site
characterization were reviewed; only those validated data considered to reflect current
conditions were included in the actual risk characterization. This provided that the data
used were of sufficient quality to reduce the uncertainty associated with estimating
exposure point concentrations.
2.3.1 COC Selection
Constituents of concern (COCs) were selected based on the criteria set forth by the
MCP guidance document (MADEP, 1995) with reference to the United States
Environmental Protection Agency’s (USEPA’s) Risk Assessment Guidance for
Superfund (RAGS; USEPA, 1991). In the first step of the selection process,
constituents were retained only if they were detected at least once in a particular
medium. All constituents that met the above criteria were considered COCs unless
they required elimination per the following criteria:
•
The constituents were present at a low frequency of detection and in low
concentrations (relative to the method detection limit).
•
The constituents were present at levels consistent with “background”
concentrations for the area and there was no evidence that their presence was
related to site activities.
•
The constituents were field or laboratory contaminants (designated as “B”).
•
All the reported values for a particular constituent in a particular media were
qualified as “J” – the values were only estimated and below the reported sample
quantitation limit (SQL); therefore, the results were uncertain and not appropriate
for use in quantitative risk estimates.
Selection rationale for individual COCs are presented in the risk assessment (BBL,
2000a).

2.3.2 Exposure Pathway Conceptual Model
Based on the current and future use conditions, an exposure pathway conceptual
model was developed to identify potential human receptors. The following five potential
receptors were identified for further evaluation:
•
General Worker: Individual involved in the day-to-day operations at the plant;
spends the majority of the on-site time in operational buildings. (Current and
identifiable foreseeable use of the site are expected to remain in place, such as
process areas and loading facilities, precluding new building construction).
•
Utility Worker: Individual engaged in ground-intrusive activity associated with
repairing or laying utility lines or pipe. Relevant media include soils and
groundwater for very limited exposure frequencies, but longer exposure periods.
•
Construction Worker: Individual engaged in ground-intrusive activity associated
with construction activity. Relevant media include soils for longer frequencies, but
shorter exposure period.
•
Maintenance Worker: Individual involved in maintaining the physical plant
including routine maintenance, trash collection and yard and road maintenance.
2.3.3 Exposure Pathways
The potential exposure pathways for each receptor population were provided in the risk
assessment (BBL, 2000a) and are presented in Table 2. These represent the most
quantitatively important pathways for which humans may be exposed to site-related
constituents. Certain of these potential exposure pathways may appear unlikely or
insignificant, but they are nonetheless routinely considered in the risk assessment
process. Table 2 lists the exposure pathways and potentially exposed site populations,
whether or not a particular exposure pathway is complete for a particular population, as
well as the rationale for selection or exclusion of the exposure pathway. Pathways
considered for each potentially exposed population include ingestion, dermal and
inhalation exposure to constituents in surface soil and subsurface soil, and in
groundwater.

No
General worker will not routinely be
exposed to subsurface soil (i.e., groundintrusive activity not expected for general
workers). There are currently no
buildings, nor are there expected to be
buildings in the currently active process
areas.
Ingestion and dermal exposure to
volatile constituents in groundwater.
No
The site groundwater is not potable and
the intrusive activity putting them in
contact with the aquifer is not expected
for the general worker.
Inhalation exposure to volatile
constituents in groundwater.
Yes
The groundwater is within 30 feet of an
existing occupied building and the
average annual depth is less than 15 feet;
as such, groundwater is considered to be
a potential source of vapors to indoor air.
2.4 Summary of 2000 Human Health Risk Characterization
Threshold and nonthreshold cumulative hazards and risks for the various receptors
and exposure media for the FGHA from the risk assessment (BBL, 2000a) are
summarized in Tables 3 and 4. Characterizing the exposure to site-related constituents
via three different media to four potentially exposed human receptors at the site lead to
the following conclusions regarding site-specific risks and hazards. With one exception,
a cumulative cancer risk to a construction worker (attributable to exposure to VC in
subsurface soil), a condition of “No Significant Risk of Harm to Human Health” was
determined at the site. This determination was based on the criteria of a cumulative
cancer risk threshold of 1 in 100,000 (1E-05), set forth at 310 CMR 40.0993(7), which
was the driver for further response actions and remediation. Other concentrations of
COCs in all areas and all exposure media did not result in cumulative hazards or risks
constituting “significant risk of harm.”

noncancer risks are lower than utility worker.
2.5 Cleanup Objectives
Based on the original 2000 risk assessment, a risk-based VC soil cleanup objective
was calculated (BBL, 2000a). However, the calculated value was higher than the 1993
MCP UCL for VC (20 mg/kg)1. Accordingly, the remedial objective was to degrade the
average VC concentration in soil to below the UCL (BBL, 2000a) in order to achieve an
acceptable residual risk level and eliminate the UCL exceedance; both conditions were
1
The UCL for VC in soil was subsequently changed form 20 mg/kg to 300 mg/kg as
par t of the 2003 revisions to the MCP, effective April 6, 2006

required to achieve a condition of No Significant Risk (NSR) for continued industrial
land use.
According to the risk assessment, the site-specific cleanup criteria for VC in soil was
calculated (BBL, 2000a); however, because this value was higher than the 1993 MCP
UCL for VC (20 mg/kg), the cleanup objective was set at the current default UCL of 20
mg/kg.
2.6 Imminent Hazard Evaluation
The site was evaluated for imminent hazards per the Imminent Hazard Evaluation
(IHE), as described in 310 CMR 40.0950. The relevant human receptors for the IHE,
given the short period of time considered in the evaluation, would be the general
worker and the maintenance worker. These individuals are on site on a daily basis, and
represent the greatest exposure potential to site constituents. Based on the conceptual
exposure model developed as part of the Method 3 Risk Characterization, the primary
exposure media likely encountered by these receptors (surface soil and groundwater)
was considered in the IHE as described below.
As described in MCP Phase II Report (BBL, 2000a), the surface soils represent a small
fraction of the total site area. Based on a review of the available data, the small area
does not contain constituent concentrations that would cause it to be characterized as
a "hot spot," which according to the MCP "shall be the primary, but not exclusive focus"
of the IHE. In fact, the maximum surface soil concentrations reported from the most
recent sampling effort were below the S-3 Soil Standards. Therefore, the surface soils
currently found on site do not constitute an imminent hazard to human health.
According to the MCP, groundwater should be considered in the IHE to evaluate
drinking-water exposures. As described MCP Phase II Report (BBL, 2000a), the
groundwater beneath the site, which has been impacted by facility activities, is not
currently a drinking-water source. There are no future plans to use the groundwater as
a drinking-water supply. Therefore, the groundwater was not considered a relevant
exposure pathway for consideration in the IHE.
In summary, the site conditions and uses, as they currently exist and will exist for the
foreseeable future, were evaluated to determine if an imminent hazard exists at the
site. Given the unique conditions found at the site (i.e., minimal accessible surface soil,
groundwater [not a drinking-water supply]) and the relatively low concentrations of site

constituents reported in the most recent sampling effort, it was determined that an
imminent hazard does not exist at the site.
2.7 Characterization of Risk to Safety
Risk to public safety was characterized in accordance with 310 CMR 40.0960.
ARCADIS evaluated conditions within the disposal areas to determine if they pose or
may pose a threat to public welfare and safety. This evaluation considers, for example,
threat of fire or explosion, rusted or corroded drums, presence of uncontainerized
materials that may pose a risk due to corrosivity, reactivity and/or infection potential,
and conditions that currently or in the foreseeable future would pose a threat of
physical harm or bodily injury to people.
The site is an active manufacturing plant that is operated in accordance with applicable
federal, state and local safety requirements. Solutia employs health and safety
personnel to maintain compliance with the required safety standards. In accordance
with the Occupational Safety and Health Administration (OSHA) standards, Solutia has
safe operating policies and procedures in effect to maintain safe conditions on site. No
readily obvious or known site-related conditions exist that pose or may pose a threat to
safety beyond those of a typical industrial/manufacturing environment. Therefore, the
conclusion of this safety evaluation is that there is no significant risk (i.e., no threat of
physical harm or bodily injury to people) related to the release or threat of release of
materials at the site disposal areas.
2.8 Environmental Risk Characterization
A site-specific baseline risk characterization was deemed unnecessary due to the
results of a Stage I Environmental Screening. The results of the Stage I Environmental
Screening areas are discussed below.
No visible impacts were observed to have occurred to wildlife. Complete exposure
pathways do not exist on the site due to lack of suitable habitat for wildlife species.
Also, adjacent areas did not have any recordings of species of concern, and no ACECs
were within one mile of the investigation areas. Therefore further risk characterization
was deemed unnecessary.
As a result of the findings of Stage I Environmental Screening, it is concluded that a
level of no significant risk of harm to the environment exists for both current and future
conditions for the FGHA area of the site.

2.9 Post-Remediation Sampling
Between May 2000 and May 2006, 73 post-injection soil samples were collected in the
target area to assess remedial progress and re-evaluate risk.
An average concentration of VC in soil was provided in the Phase V ROS Report
(BBLES, 2006). These post-remediation data support that the average concentration
within the source area (hot spot and target area) is below the current UCL of 300
mg/kg. In addition, the 19 post-treatment soil samples collected from the target area in
October 2000 were not included in the average provided in the Phase V ROS Report
(BBLES, 2006). These post-treatment soil samples further lowered the average soil
concentration in the target area from 108 mg/kg to 94 mg/kg (Table 5), and from 160
mg/kg to 130 mg/kg for all soils (Table 6.
In addition, eight rounds of groundwater samples for VOCs were collected to evaluate
NA and the effectiveness of soil treatment. Based on historical groundwater sampling
analytical results, VC concentrations have decreased from 1998 to 2008 as a result of
ongoing NA. A significant decrease in VC concentrations was observed post-injection
(i.e., after April 2000) and has not rebounded (Appendix B). Although quarterly
groundwater sampling has not been completed, 12 years of annual monitoring has
been completed during each season (winter, spring, summer and fall) to evaluate
seasonal trends. As shown in Appendix B of the REDUA (Attachment 1 – Seasonal
Groundwater Concentration Monitoring Graphs), there were no conclusive seasonal
trends. The decreasing concentrations were observed occurred regardless of season
and/or changes in water table elevation.
As discussed in Section 3.3 of the attached REDUA (Appendix B), VC remains present
below UCLs in the subsurface as partially polymerized PVC. However, the decrease in
groundwater concentrations support that in-situ soil treatment has reduced the source
in soil to levels suitable for continued NA, as demonstrated in the MCP Second SemiAnnual Release Abatement Measure 2002 Status Report (BBL, 2002b) and confirmed
in six subsequent groundwater sampling events. Concentrations in groundwater have
always been and continue to be below target GW-3 criteria. Since in-situ treatment,
groundwater concentrations in groundwater have decreased and the plume extent is
stable.
Twelve groundwater sampling events have occurred annually prior to, during and postremediation from February 1997 to July 2008 in winter, spring, summer and fall

seasons for VOCs (see Appendix B, Attachment 1 – Seasonal Groundwater
Concentration Monitoring Graphs).
For each event, the VC concentrations and any associated trends are well documented
and have been replicated through the years, supporting the accuracy of the data as
well as the following supporting conclusions:
•
•
•
VC concentrations in groundwater are decreasing
VC concentrations decrease independent of the season and water table elevation
extent of VC in groundwater is stable or decreasing
Although VC remains present in the subsurface as partially polymerized PVC, the
decrease in groundwater concentrations support that in-situ treatment has reduced the
source in soil to levels suitable for continued NA, as demonstrated in the MCP Second
Semi-Annual Release Abatement Measure 2002 Status Report for Former VC Gas
Holder Area RTN 1-11901 (BBLES, 2002b) and confirmed in six subsequent
groundwater sampling events. Concentrations in groundwater have always been and
continue to be below target GW-3 criteria and are stable or diminishing through time,
as demonstrated by time series plots (Appendix B, Figure 5).
Per Tables 1 and 2 of the REDUA (Appendix B), soil and groundwater samples were
collected to meet presumptive certainty requirements (i.e., Level IV reporting package
that complies with the MassDEP’s content, format and certification requirements). In
addition, beginning in 1999, soil for VOC analyses was collected using EncoresTM for
laboratory preservation with methanol and sodium bisulfate.
2.10 Post-Remediation Reassessment of Risks
ARCADIS completed a reassessment of risk following remediation and post-injection
sample collection to evaluate potential utility upgrades in the FGHA. In the initial site
assessment, the construction worker’s cumulative cancer risk attributable to exposure
to VC in subsurface soil was the only exposure that exceeded the criteria of a
cumulative cancer risk threshold of 1 in 100,000 (1E-05), set forth at 310 CMR
40.0993(7). As a result, in addition to reassessing the utility worker risks, cancer and
noncancer risks posed to the construction worker were also reassessed.
Based on the risk assessment completed by BBL in 2000, a condition of NSR of harm
to human health was demonstrated for a utility worker in the FGHA, assuming one 8hour day of excavation per year for 25 years (BBL, 2000a), but not for a construction

worker, which assumes 125 eight-hour days of excavation for one year. A condition of
NSR was determined assuming an exposure point concentration (EPC) for VC of 490
mg/kg, the maximum concentration detected within the source area of the FGHA
consistent with the requirements of the MCP 40.0926(3)(b)(2) as of January 2000. In
the risk assessment completed in 2000, it was conservatively assumed that 100
percent of utility activity would occur in the FGHA source area.
The default MassDEP-recommended value for the duration of a utility worker exposure
scenario is one 8-hour work day for one event per year. This is the value that was
appropriately used in the risk assessment presented in the MCP Phase II CSA Report
(BBL, 2000a). However, it is possible that a utility worker could be working within the
aerial extent of the treatment area (previously the source area) at the FGHA for an
extended period, possibly for 3 to 5 days. Therefore, risk was re-evaluated for a
hypothetical 5-day period, as well as for the maximum acceptable exposure duration
for a utility worker, using post-remediation data. In this reassessment, it was assumed
that the exposure frequency for groundwater remained at one day per year, consistent
with the exposure assessment in the 2000 risk assessment. This assumption states
that although direct contact with groundwater may occur, it is assumed that the
exposure “would be experienced only occasionally by laborers repairing pumps used to
dewater excavation holes, an activity that would result in an acute exposure.”
In addition to the expected change in exposure duration by the utility, remedial
activities at the site have resulted in an overall decrease in the VC concentration in the
FGHA. The maximum concentration of VC detected in soil in 1997 was 490 parts per
million (ppm), with a frequency of detection of 13 of 28. Evaluation of the data
according to the MCP requirements indicated that the EPC should be a conservative
estimate of the site average [40.0926(3)(b)(2)]. Therefore, the maximum concentration
was used to determine risk for the site in completing the original site assessment (BBL,
2000a). Post-remediation data show a frequency of detection of 17 of 73 and an
average of 108 ppm (BBLES, 2006). Evaluation of the more recent soil data [per MCP
40.0926(3)(b)(2)] indicates that a simple arithmetic average adequately represents the
soil data. This is because 75 percent of the data points used in the averaging are less
than the average concentration and no data point used is greater than 10 times the
resulting average (BBLES, 2006) (MassDEP, 2006).
Post-remediation groundwater monitoring in the FGHA shows a decrease in
constituent concentrations (BBLES, 2006). As a result, the EPCs have been modified
to reflect the most current data collected in 2006 (BBLES, 2006). Review of the
groundwater data (1986 through 2006) indicated that several compounds not detected

prior to early 1999 (when the initial risk assessment was completed) were detected in
groundwater at low concentrations. These data are evaluated for frequency and
magnitude of detection for the amended risk assessment (Table 7). Any data detected
at a frequency of less than 10 percent and at concentrations not exceeding the
applicable GW Method 1 Standards were eliminated from further consideration. For the
remaining compounds, the maximum concentrations from 2006 were used as the EPC
concentrations (Table 7). Ambient air concentrations were calculated as described in
Section 7.3.3.2 of the original risk characterization (BBL, 2000 a), and are presented in
Table 7.

In the initial site assessment, the construction worker’s cumulative cancer risk
attributable to exposure to VC in subsurface soil was the only exposure that exceeded
the criteria of a cumulative cancer risk threshold of 1 in 100,000 (1E-05), set forth at
310 CMR 40.0993(7). As a result, in addition to reassessing the utility worker risks,
cancer and noncancer risks posed to the construction worker were also reassessed.
This new evaluation of risk at the FGHA included the use of the more recent data
(arithmetic average of 108 ppm for VC), any revised toxicity values since 2000 and any
modified default exposure assumptions. Table 8 is an excerpt from the original risk
assessment document, and the revised exposure assumptions are highlighted and
bolded. Table 9 outlines the toxicity factors that were modified to reflect the values
currently available from the MassDEP (http://www.mass.gov/dep/service/compliance/

Using the assumptions outlined in Table 8, the reassessment of risk resulted in NSR of
harm to human health based on the criteria of a cumulative cancer risk threshold of 1 in
100,000 (1E-05) and a cumulative noncancer hazard index equal to one, set forth at
310 CMR 40.0993(7) for both the utility worker and construction worker. As a result,
the total (groundwater plus soil) cancer and noncancer risks posed to the utility worker
at the FGHA is 3.9E-06 and 1E-02, respectively (Table 10). These values assume a
maximum exposure frequency for the utility worker of 5 days per year for soil, and 1
day per year for groundwater.
Assuming a utility worker is assumed to be actively repairing utilities in the FGHA for a
conservative exposure duration of 20 days per year2, the resulting cancer risk is within
an acceptable risk at 9.8E-06 for soil and 1.5E-06 for groundwater (with the exposure
frequency for groundwater assumed to be no greater than 1 event per day). The
noncancer hazards are 3E-02 and 6E-03 for soil and groundwater, respectively. The
resulting total cancer and noncancer risks are 1.1E-05 and 4E-02, respectively. These
values are less than or essentially equal to the criteria of NSR established by 310 CMR
40.0993(7) (a cumulative cancer risk threshold of 1 in 100,000 [1E-05] and a
cumulative noncancer hazard index equal to one). As a result, a utility worker exposed
to site conditions as described, for 20 days, will not be exposed to any significant
increase in risk.

3. Response Action Outcome
A Class A RAO is applicable to the site as described in this RAO Statement because
remedial response actions were conducted. Subsequently, a condition of NSR has
been achieved without Phase V operation, maintenance and or monitoring activities to
maintain a condition of NSR.
3.1 Class of RAO
This RAO Statement complies with 310 CMR 40.1056 and applies to the FGHA portion
of the Solutia Property. A Class A-3 RAO reflects the following considerations:
•
Permanent Solution has been achieved
•
level of oil and hazardous material in the environment has not been reduced to
background
•
one or more Activity and Use Limitations have been implemented pursuant to 310
CMR 40.1012 to maintain a level of NSR
•
oil or hazardous material at the disposal site do not exceed an applicable UCL in
soil or groundwater listed at 310 CMR 40.0996(7)
3.2 Relationship of RAO to Other RAOs
This RAO does not cover the other areas (RTN 1-0184), of the Solutia Indian Orchard
Plant Property, which includes 14 disposal areas. These areas are being addressed
separately by Solutia in a Supplemental RCRA Facility Investigation/MCP Phase II
CSA submitted to the USEPA and the MassDEP in April 1996 (BBL, 1996), a Revised
Phase II and Method 3 Risk Assessment in June 2007 (ARCADIS-BBL, 2007) and an
MCP Phase III in January 2008 (ARCADIS-BBL, 2008). RTN 1-0184 encompasses the
remainder of the Solutia Indian Orchard Plant not addressed with the activities at the
FGHA. The RTN 1-0184 portion of the property is currently being addressed under a
MassDEP RCRA program using MCP process.
3.3 Condition of No Significant Risk
ARCADIS prepared this RAO Statement on behalf of Solutia. This RAO Statement was
prepared as part of response actions conducted under the MCP 310 CMR 40.0000

associated with the site. As described in this RAO Statement, response actions have
been completed and the remedial goals were met as presented in the Final 2006 SemiAnnual Remedy Operation Status/Phase V Operation, Maintenance, and Monitoring
Report (BBLES, 2006).
The Method 3 Risk Characterization prepared for the Phase II CSA Report (BBL,
2000a) and re-assessment of risks concluded that a condition of NSR of harm to
human health was demonstrated for potential receptors, including a general worker,
utility worker in the FGHA assuming one 8-hour day of excavation per year for 25 years
(BBL, 2000a) and a construction worker assuming 125 eight-hour days in one year
(BBLES, 2006). In addition, BBL determined that a utility worker exposed to current site
conditions at the FGHA for 20 days per year would not be exposed to any significant
increase in risk. The supplemental evaluation, performed in 2006 (BBLES, 2006) using
updated analytical data, determined that utility workers working in the former source
area for up to 5 days per year were at NSR of harm to human health as well. The
construction worker was also reassessed at this time, with a finding of NSR of harm to
human health (BBLES, 2006). However, an AUL is required to maintain the current
land use assumed in the risk assessment.
A copy of Bureau of Waste Site Cleanup (BWSC) transmittal form BWSC104 is
included in Appendix 1.
3.4 AUL
In accordance with the MCP 310 CMR 40.1074, an AUL Opinion was prepared to
support a condition of NSR for a portion of the Solutia Property located at 730
Worcester Street, Springfield, Massachusetts. A certified copy of the AUL is provided in
Appendix C.
An AUL is required to maintain a condition of NSR. A site-specific MCP Method 3 Risk
Characterization and a post-remediation Method 3 reassessment have shown that the
site poses NSR based on the current industrial land use and implementation of certain
access restrictions assumed in the risk assessment. That is, although post-remediation
soil concentrations have decreased to below the remedial objectives consistent with
industrial land use (i.e., below UCLs), the risk assessment assumed that future land
use associated with residential, day care, school and recreational areas would be
prohibited. As such, land use other than commercial/industrial land use must be
restricted.

•
Residential development or use as a park, school, nursery, daycare, public
recreational area and/or other such use where frequent (e.g., daily) direct contact
by children and/or adults involved in high-intensity activities (such as contact
recreation, dirt bike riding and/or gardening) within Areas 1 and 2.
•
Agricultural uses, including vegetable gardening and grazing of livestock within
Areas 1 and 2.
•
Relocation of soil affected by visual fine white granular material potentially located
at depths greater than 3 feet below the surface grade (approximately at 141 feet
above mean sea level [amsl]) to a shallower depth within Area 2, unless activity is
first evaluated by a Licensed Site Professional who renders an opinion that such
relocation is consistent with maintaining a condition of NSR.
•
Long-term (i.e., involving an individual worker spending more than a total of 125
eight-hour days) intrusive work (including underground demolition, construction or
nonemergency utility work) within Area 2 that may result in unrestricted direct
contact with, or potential disturbance of (including, but not limited to, permanent
removal of and/or relocation) soil at depths 3 feet or greater below the surface
(approximately at 141 feet amsl), unless such work is conducted in accordance
with the MCP (310 CMR 40.0000) and the obligations and conditions identified in
Section 5 of this RAO Statement.
•
Permanent removal of the top 3 feet of soil within Area 2 without replacement by
an equivalent thickness of suitable material (e.g., soil, asphalt, gravel, crushed
stone).
•
Any activities and uses within Area 2 not listed above that may result in high
frequency and/or high-intensity contact with soil.

3.5 Feasibility of Achieving Background
MassDEP regulations describe conditions when it is not feasible to cleanup a site to
background levels for COCs. These conditions include the following:
1. If achieving background levels requires the excavation of soils from under the
foundation of a building or other permanent structures, such that the integrity of the
structure may be compromised (e.g., [FGHA]).
2. When COCs are attributed to coal or wood ash associated with fill material.
3. When COCs are associated with releases to groundwater from a water supply
system.
4. When petroleum residues occur that are incidental to normal operation of a motor
vehicle.
5. When degradable/nonpersistent compounds are present, except for small volumes
considered to be easily accessible (e.g., <3 feet deep).
6. When persistent compounds are present, but are located in areas with lower
exposure potential, such as S-3 category soils (e.g., chloroethene).
An excavation alternative was considered to fulfill requirements to evaluate the
feasibility of achieving background in the MCP Phase III Remedial Action Plan and
Phase IV Remedy Implementation Plan (BBL, 2003b). This alternative involves the
excavation underneath buildings, and around underground utilities and manufacturing
structures. This scenario was considered impractical, because it would require the
removal of buildings, utilities and surrounding structures. The incremental cost of
conducting an excavation remedial alternative and building and manufacturing
structure replacement is substantial and disproportionate to the incremental benefit or
risk reduction, environmental restoration and monetary and nonpecuniary value.
Considering the risks to structures involved in implementing this solution, the cost
benefit and the significant disruption to ongoing operations at the site and to buildings
and/ or building foundations, achieving background is not feasible.

5. Conclusions/LSP Opinion
This Class A-3 RAO applies to the FGHA portion (RTN 1-11901), in the eastern portion
of the Solutia Indian Orchard Plant. This RAO does not cover the other areas (RTN 10184), of the Solutia Indian Orchard Plant Property. RTN 1-0184 is addressed
separately by Solutia in a Supplemental RCRA Facility Investigation/MCP Phase II
CSA submitted to the USEPA and the MassDEP (BBL, 1996), Revised Phase II and
Method 3 Risk Assessment (ARCADIS_BBL, 2007) and an MCP Phase III evaluation
in January 2008. RTN 1-0184 encompasses the remainder of the Solutia Indian
Orchard Plant not addressed with the FGHA RTN 1-11901.
As described in this RAO Statement, response actions have been completed and the
remedial goals were met as presented in the Final 2006 Semi-Annual Remedy
Operation Status/Phase V Operation, Maintenance, and Monitoring Report (BBLES,
2006).
The source of PVC to soil has been eliminated as the PVC manufacturing process was
terminated in 1975. The residual PVC remaining in soil post treatment has been
reduced to an average concentration below UCL. Given that groundwater
concentrations have been reduced, the extent in groundwater has stabilized and trends
for concentrations and extent continues to decrease over the past 7 years, the source
to groundwater is under control.
The Method 3 Risk Characterization prepared for the Phase II CSA Report (BBL,
2000a) and re-assessment of risks (BBLES, 2006c) concluded that a condition of NSR
of harm to human health was demonstrated for potential receptors, including a general
worker, utility worker in the FGHA assuming one 8-hour day of excavation per year for
25 years (BBL, 2000a) and a construction worker assuming 125 eight-hour days in a
year (BBLES, 2006c).
Using revised and current toxicity factors and the available average of 108 mg/kg, a reassessment of risk was evaluated for a construction worker and a utility worker postremediation (BBLES, 2006c). The reassessment confirmed the original Method 3 risk
assessment results for a utility worker (i.e., a condition of NSR existed for this receptor)
and that a condition of NSR was achieved for a construction worker. Although
reassessment was not performed on a general worker or maintenance worker, a
condition of NSR already existed for these receptors prior to remediation. Therefore,
not only was the remedial objective achieved by reducing average concentrations to
below UCLs, but the average concentration achieved met a condition of NSR through a

Method 3 reassessment of risks (Attachment 2 of the Appendix B). However, average
concentration values used for the reassessment of risk are actually lower when
including the initial post-injection soil samples collected in October 2000. The revised
averages are presented in Tables 5 and 6.
As a result of the findings of Stage I Environmental Screening, it is concluded that a
level of no significant risk of harm to the environment exists for both current and future
conditions for the FGHA area of the site.
Risk to public safety was characterized in accordance with 310 CMR 40.0960 to
evaluate conditions within the disposal areas to determine if they pose or may pose a
threat to public welfare and safety. The conclusion of this safety evaluation is that there
is no significant risk (i.e., no threat of physical harm or bodily injury to people) related to
the release materials at the site disposal area.
An excavation alternative was considered to fulfill requirements to evaluate the
feasibility of achieving background in the MCP Phase III Remedial Action Plan and
Phase IV Remedy Implementation Plan (BBL, 2003b) and was deemed not feasible.
Achieving background conditions is considered impractical, because it would require
the removal of buildings, utilities and surrounding structures. The incremental cost of
conducting an excavation remedial alternative and building and manufacturing
structure replacement is substantial and disproportionate to the incremental benefit or
risk reduction, and environmental restoration.
The site conditions and uses, as they currently exist and will exist for the foreseeable
future, were evaluated to determine if an imminent hazard exists at the site. Given the
unique conditions found at the site (i.e., minimal accessible surface soil, groundwater
that is not a drinking-water supply) and the relatively low concentrations of site
constituents reported in the most recent sampling effort, it was determined that an
imminent hazard does not exist at the site.
Although post-remediation soil concentrations have decreased to below the remedial
objectives consistent with industrial land use (i.e., below UCLs), the risk assessment
assumed that future land use associated with residential, day care, school and
recreational areas would be prohibited. As such, an AUL has been applied to the
property at the specific location identified in the attached AUL (Appendix C).

1. Introduction
This Data Representativeness Evaluation and Data Usability Assessment (REDUA)
was prepared to address Massachusetts Contingency Plan (MCP; 310 CMR 40.0000,
effective December 14, 2007) (Massachusetts Department of Environmental Protection
[MassDEP], 2007a) requirements related to site closure. As described in Section
40.1056(2)(k) of the MCP, the purpose of a REDUA is to document that the data upon
which a Response Action Outcome (RAO) is based are valid and defensible; are of
sufficient level of precision, accuracy and completeness; and are spatially and
temporally adequate. This REDUA has been prepared to address these requirements,
and is provided in support of a Class A-3 RAO for a portion of the Indian Orchard Plant
Site (i.e. the Former Vinyl Chloride Gas Holder Area) in Springfield, Massachusetts
(Massachusetts Department of Environmental Protection [MassDEP] Release Tracking
Number [RTN] 1-11901) (site; Figure 1).
Guidance available from the MassDEP (MCP REDUA Policy #WSC-07-350 [Policy]
[dated September 19, 2007] [MassDEP, 2007b]), was relied upon for guidelines
regarding the purpose, approach and content of a REDUA. This REDUA summarizes
the results of the site-specific REDUA, and is organized as follows:

2. Data Summary
As described in Table 2 of the MCP REDUA Policy there are several types of analytical
data, as follows:
•
CAM-compliant data – analytical data generated after August 1, 2003, that achieve
“presumptive certainty” (i.e., analytical data that meet the requirements of
MassDEP’s Compendium of Analytical Methods [CAM; established August 1,
2003])
•
Pre-CAM data – analytical data generated prior to August 1, 2003, before
MassDEP’s establishment of CAM requirements and associated requirements for
completing REDUAs
•
CAM noncompliant data – analytical data compiled after August 1, 2003, using
analytical methods included in the CAM, but in a manner that is not consistent with

3.1 Conceptual Site Model
The Former Vinyl Chloride Gas Holder Area (FGHA) is a Tier II-classified site located
on the Solutia portion of the Indian Orchard Plant near a former aboveground process
vessel (“gas holder tank”) that recycled vinyl chloride (VC; Figure 2). VC was used in
the process vessel in the southern portion of the site at former Building 85 during the
manufacture of polyvinyl chloride (PVC) from 1946 to 1975.
Volatile organic compounds (VOCs), consisting primarily of VC, exist in a layer of fine,
white granular material (partially polymerized PVC) approximately 5 to 6 feet below
ground surface (bgs) next to the former location of the process vessel. The source of
the VC detected in soil and groundwater is likely from the VC vapor condensation
holder process vessel, which contained residual and partially polymerized PVC. The
vessel may have been emptied onto the ground and then buried when the area was
regraded.
Prior to treatment, the layer of white material (confirmed to be off-specification,
standard-grade PVC or partially polymerized PVC) exhibited concentrations of VC up
to approximately 450 milligrams per kilogram (mg/kg), which exceeds current MCP
upper concentration limits (UCLs), with lesser concentrations of trichloroethene, 1,2dichloroethene and 1,2-dichloroethane detected above MCP reportable concentrations
but below UCLs. The partially polymerized PVC is in contact with groundwater, as the
water table is shallow (ranging between approximately 3 to 4.5 feet bgs). Although VC
from the partially polymerized PVC leaches to the groundwater, the maximum VC
concentrations in groundwater in this area (0.24 milligrams per liter [mg/L]) are three
orders of magnitude below the GW-3 standard of 50 mg/L.
Groundwater flow direction at the Former VC Gas Holder Area is toward the southwest,
as presented in the MCP Phase II Comprehensive Site Assessment Report for RTNs
1-10793, 1-10868, 1-10869, 1-11692, 1-11693, 1-11694, and 1-11901 Investigation

subsequent status reports prepared for Solutia by BBL (BBLES, 2001b, 2002a, 2002b,
2003a, 2003b, 2004a, 2004b, 2005a, 2005b, 2006a, BBLES ARCADIS, 2006b). The
dissolved VC plume in groundwater has been defined and is within the Solutia property
boundaries (BBL, 2000a, 2001a, 2001b). The plume does not extend to the Chicopee
River. The downgradient edge of the plume is located more than 700 feet hydraulically
upgradient from the river (BBL, 2000a, 2000b, 2001a). The groundwater

concentrations have been decreasing and the plume extent is either reducing or static.
Based on a solute transport analytical model, natural attenuation (NA) parameter
monitoring and historical VOC monitoring, NA is ongoing (BBL, 2002b, BBLES
ARCADIS, 6b).
The Method 3 risk characterization provided in the MCP Phase II CSA Report (BBL,
2000a) evaluated potential soil, groundwater, surface water and sediment exposure
pathways and potential receptors. Five potential on-site receptors were identified in the
risk characterization for further evaluation:
•
General Worker: Individuals involved in the day-to-day operations at the plant;
spend the majority of the on-site time in operational buildings.
•
Utility Worker: Individual engaged in ground-intrusive activity associated with
repairing or laying utility lines or pipe. Relevant media include soils and
groundwater for very limited exposure frequencies, but longer exposure periods.
•
Construction Worker: Individual engaged in ground-intrusive activity associated
with construction activity (relevant media include soils for longer frequencies, but
shorter exposure period).
•
Maintenance Worker: Individual involved in maintaining the physical plant
including routine maintenance, trash collection and yard and road maintenance.
•
Recreational User: Does not visit on site, but has the potential to be in contact
with the Chicopee River during recreational activities.
The exposure profiles evaluated in the Method 3 Risk Characterization (BBL, 2000a)
represented the greatest potential exposures based on likely current and reasonably
foreseeable receptors, receptor age, frequency and intensity of use, and accessibility,
as per 310 CMR 40.0933 As a result of the physical restrictions to prevent
unauthorized access to the facility, adults are the only potential current receptors. The
potential exposure pathways for each receptor population evaluated represented the
most quantitatively important pathways for which humans may be exposed to siterelated constituents. Pathways considered for each potentially exposed population
include ingestion, dermal and inhalation exposure to constituents in surface soil and
subsurface soil, as well as ingestion, dermal and inhalation exposure to constituents in
groundwater (BBL, 2000a).

Given that land use is industrial for the current and foreseeable future, residential
receptors were not considered. Furthermore, because on-site and surrounding
groundwater is not used for drinking water (nor meets the transmissivity criteria as
potentially productive) and potable water is supplied to the plant and surrounding areas
by a public water supply, groundwater potable use was not considered. Therefore,
groundwater at the FGHA is not classified as GW-1. Groundwater is classified as GW2, in addition to being classified GW-3, because the depth to groundwater at the site
averages less than 15 feet bgs. This classification conservatively assumes that a
building may be constructed at the site, if one does not exist already.
Considering the type of activities likely to occur at the Former VC Gas Holder Area and
the frequency of exposure, the exposure potential can be currently classified, pursuant
to the MCP, as “low frequency/high intensity,” “high frequency/low intensity” and “low
frequency/low intensity.” Given these combinations of receptor age, accessibility of soil,
and frequency and intensity of exposure, soil categories S-2 and S-3 currently apply at
the site and will continue to apply under the current commercial/industrial land use
scenario.
Based on the Method 3 risk characterization, except for the construction worker’s
cumulative cancer risk attributable to exposure to VC in subsurface soil, a condition of
“No Significant Risk of Harm to Human Health” has been demonstrated based on the
criteria of a cumulative cancer risk threshold of 1 in 100,000 (1E-05), set forth at 310
CMR 40.0993(7). The threshold and nonthreshold cumulative hazards and risks for the
various receptors and exposure media were summarized in the risk characterization
and are presented in Tables 3-1 and 3-2. Other concentrations of constituents of
concern (COCs) in all areas and all exposure media did not result in cumulative
hazards or risks constituting “significant risk of harm.”

Pursuant to the risk assessment conclusions, soil remediation was completed at the
Former Gas Holder Area to reduce the concentrations of VC in the soils to MCPestablished UCLs or the site-specific remedial goals developed based on the Method 3
risk characterization, whichever was lowest.
In-situ chemical oxidation treatment using sodium permanganate was completed in
three separate injection events (May/June 2000, March 2001 and November 2004) to
treat the subsurface and source to groundwater (BBLES ARCADIS, 2006b). The initial
soil concentration detected in the target area was reduced from 470 mg/kg to an
average at 160 mg/kg. Post-treatment soil concentrations are below the target UCL
remedial goal of 300 mg/kg.
A condition of No Significant Risk of Harm to Human Health was achieved, following a
re-assessment of site risks to construction worker and utility worker using posttreatment soil concentrations.
3.2 Sampling Rationale
For all events, soil sample location and depths, and groundwater monitoring well
locations and screened intervals (which monitor various groundwater zones) were
selected to support site delineation and risk characterization efforts. Further, locations
were selected based on direct knowledge anecdotal information related to historical
site operations. The findings of the investigations support the recorded information
regarding historical use. As a result, sampling locations have provided representative
analytical data that adequately characterize the site area.

3.2.1 Groundwater
Groundwater sampling and analysis has been conducted annually from July 1986 to
May 2006 to accomplish the following:
•
characterize the nature and extent of groundwater impacts
•
evaluate concentration trends following the source-area in situ chemical oxidation
treatment in 2000
•
determine the effectiveness of natural attenuation
Based on the groundwater analytical data, the primary constituent of interest is VC with
ethylbenzene, styrene, toluene and xylenes detected infrequently or sporadically.
Generally, nine wells (MW-58S, MW-83S, MW-87S, MW-92S, MW-93A, MW-94S,
MW-95S, MW-96SF and MW-98D) are sampled annually to provide data related to site
COCs in groundwater (Figure 3). A trend of decreasing VC concentrations further
supports a monitored NA (MNA) remedy. The COCs in the site area have been
delineated (BBL, 2000a; BBLES, 2002a, BBLES ARCADIS, 2006b. The plume is well
characterized, and as based on historical groundwater sampling analytical results, VC
concentrations have decreased from December 1998 to May 2006 in support of
ongoing NA. The groundwater flow direction is also evaluated seasonally and is
consistently toward the west (Figure 4).
3.2.2 Soil
Soil sampling events were conducted in the FGHA in January/February 1997, April
1997, August 1997, December 1998, June 2000, October 2000, June 2001 and May
2006. Within the FGHA, a total of 99 soil samples from depths ranging from 2 to 24 feet
have been collected from 65 borings (Figure 2). Based on the soil analytical data, the
primary constituent of interest is VC with 1,2-dichloroethane (1,2-DCA), 1,2dichloroethene, tetrachloroethene (PCE), trichloroethene (TCE), acetone, benzene,
ethylbenzene and toluene detected less frequently and sporadically.
Most of the samples were taken from depths of 4 feet or greater based on field
screening in order to target the source area (i.e., a layer of off-specification product, as
discussed in Section 3.1). Twenty-eight of the 99 soil samples were collected in June
and October 2000 to measure the reduction in concentrations following the injection of

sodium permanganate (BBLES ARCADIS, 2006b). These samples were used to
demonstrate the effectiveness of the injections in reducing VC concentrations in the
FGHA. A total of 15 surface soil (0 to 1 foot) samples were collected from borings to
evaluate site conditions for surface soil volatilization to ambient air conditions.
Post-injection soil data for VC were averaged and compared to the applicable MCP
standards. Soil data were averaged using the data collected in the treatment target
area (hot spot) pre- and post-treatment, as well as data around the perimeter of the
target area, for an average concentration within the target area and a total average for
the disposal site.
Based on the May 2006 post-injection soil sampling results, concentrations of VC in the
subsurface within the target zone ranged from below detection limit (0.0051 mg/kg) at
SB-132 to 550 mg/kg at SB-140.
An average VC concentration in soil of 108 mg/kg was estimated across the disposal
site per 310 CMR 40.0996 (2)(a) using current and historical data (BBLES ARCADIS,
2006b). These data include surface and subsurface soil, as well as data within the
target area and data from around the perimeter of the target area or “hot spot.”
However, it should be noted that 80 percent of the data was within the target area.
An average VC concentration in soil of 161 mg/kg was estimated for samples within the
“hot spot” per 310 CMR40.099b (2)(b) using the pre-treatment and post-treatment
historical data. This average excludes surface soil and perimeter data (BBLES
ARCADIS, 2006b).
The average VC concentration in soils around the perimeter of the target area was
estimated at 0.05 mg/kg (BBLES ARCADIS, 2006b).
Based on this evaluation, average VC concentrations of both the more recent postinjection data collected in 2006 and the historical data within the target area are below
the current UCL of 300 mg/kg.
3.3 Distribution of Samples
This component of the Representativeness Evaluation involves justifying that the
number and spatial distribution of samples within a given sampling area are sufficient
to support the RAO.

3.3.1 Number of Samples
A total of 88 groundwater samples and 99 soil samples were collected within the FGHA
(Tables 3 and 4).
3.3.1.1 Soil Samples
From 1997 to 2006, a total of 99 soil samples were collected at the Former VC Gas
Holder Area at the Indian Orchard Plant (Table 3). Of the total, 15 were surface soil
and 84 were subsurface soil. Of the 15 surface soil samples, VOCs were analyzed in
these 15 surface soil samples. Because these samples were used to determine site
boundaries and remediation limits as well as used in the Risk Assessment, they are all
considered critical samples.
Of the 84 subsurface soil samples, 79 were analyzed for VOCs. The miscellaneous
parameter (i.e., total organic carbon) was analyzed in the other five subsurface soil
samples. The 79 sample results for VOCs were used to determine site boundaries and
remediation limits as well as assess risk; as such, are all considered critical samples.
The TOC was used to evaluate physical properties of the soils.
3.3.1.2 Groundwater Analytical Data
From 1986 to 2008, a total of 159 groundwater samples were collected from monitoring
wells or temporary wells at the Former Gas Holder Area at the Indian Orchard Plant
(Table 4). Of these, 158 samples were analyzed for VOCs.
Miscellaneous analytical parameters (i.e., inorganics, gasses and biological
parameters) were also collected from 33 of the 159 groundwater samples to evaluate
the potential for MNA. Because the 105 samples for VOCs were used to determine site
boundaries, remediation limits, risks and/or confirm NA, these are all considered critical
samples.
3.3.2 Spatial Distribution of Samples
Samples, field observations and field measurements have been made at numerous
locations, as reported in various submittals to the MassDEP (BBL, 2000a; BBLES
ARCADIS, 2006b). More than 389 (2- to 4-foot interval) soil samples have been
collected out of 122 soil borings in and around the target area to define the source,
nature and extent. These soil samples were visually examined and field screened

using a photo ionization detector (PID) to select samples for further laboratory analysis.
Analytical samples are densely located within and around the FGHA target area as88
soil sample were collected and analyzed within a 3,000-foot square area (Figure 2).
The sample locations have specifically targeted the known and potential source of
release. Sample locations are also well-distributed throughout the site and are
representative of various depth intervals. For vertical distribution, 17 soil borings were
drilled to the top of the glacial till confining unit. Accordingly, the soil sample distribution
and frequency of samples are considered spatially representative of the site area.
Groundwater samples are collected from 16 monitoring wells in and around the target
area. Four of these 16 monitoring wells are hydraulically upgradient. Given that the
thickness of the saturated unit below the shallow water table (at 4 feet) above the
confining unit is found at depths greater than 30 feet at two downgradient locations,
deep and shallow well clusters monitor the vertical distribution. The monitoring wells
were installed to monitor the axis for the plume, as well as the downgradient edge of
the plume.
3.3.3 Temporal Distribution of Samples
Soil analytical sample data for the site and surrounding area date back to 1997.
Although groundwater data dates back to 1986, the majority of the groundwater data
was collected between 1997 and 2008. Data were collected through time to further
delineate the specific site area, pursue treatment options and/or monitor NA. The most
recent analytical data were collected in 2006 from soils and in 2008 from groundwater.
Twelve groundwater sampling events have occurred annually between February 1997
and July 2008 in winter, spring, summer and fall seasons, for the target constituent for
VOCs (Attachment 1 – Seasonal Groundwater Concentration Monitoring Graphs).
Through these multiple sampling events occurring for 12 years, the VC concentrations
and any associated trends are well documented and have been replicated through the
years, supporting the accuracy of the data as well as the following supporting
conclusions:
•
•
•
VC concentrations are decreasing
VC concentrations decrease independent of the season and water table elevation
extent of VC in groundwater is stable or decreasing
Although VC remains present in the subsurface as partially polymerized PVC, the
decrease in groundwater concentrations support that in-situ treatment has reduced the
source in soil to levels suitable for continued NA as demonstrated in the MCP Second

since they began decreasing in 2001. No exceedances of MassDEP criteria for
groundwater discharge to surface water (at 40 mg/L) have been detected, either pre- or
post-injection.

3.4 Field Screening Data
With the exception of using PID field units during typical field soil boring and soil
sampling activities, field screening methods were not used as part of response actions
within the site area. Further, PID data have not been used quantitatively in site
evaluations or as a basis for exclusion of any area from remedial activities.
3.5 Completeness
There are no identified data gaps for soil or groundwater in the site area. There are no
soil vapor data, but indoor air was modeled. There are no current indoor air receptors.
As discussed in the MCP Phase II CSA Report (BBL, 2000a), three different sources of
chemicals in air were identified for on-site receptors. Air exposure resulted from indoor
air from groundwater, ambient air from groundwater and ambient air from subsurface
soil.
The model used to calculate air concentrations resulting from volatilization of
constituents in groundwater into indoor air is based on Johnson and Ettinger’s (1991)
approach to modeling subsurface vapor intrusion into buildings (BBL, 2000a). To
assess inhalation exposure to constituents in groundwater for the utility worker
(ambient air), a method that models volatilization releases of compounds from water
bodies was used in conjunction with an equation that derives air concentrations from
modeled air emissions from water (United States Environmental Protection Agency
[USEPA], 1988). For ambient air from subsurface soil, volatilization factors were
calculated using the equations presented in the USEPA’s 1996 Soil Screening
Guidance: Technical Background Document. The modeled result concentrations are
presented in Table 7-15 of the MCP Phase II CSA Report (BBL, 2000a).
The risk outcome was determined to be a condition of “No Significant Risk of Harm to
Human Health” (BBL, 2000a). Although the FGHA does not border a river and the
downgradient edge of the VC plume in groundwater was more than 700 feet
upgradient from the river and not advancing, sediment and surface-water data were
reviewed as part of the Method 3 risk characterization.
3.6 Inconsistency and Uncertainty
The Representativeness Evaluation should justify that inconsistent information and
sources of uncertainty are not sufficient to undermine the RAO Opinion. The
conservative nature of the methodologies used for the risk assessment and post-

treatment risk assessment revision minimizes uncertainty. The principal uncertainty of
this Representativeness Evaluation and Data Usability Assessment is related to the
exclusion of J-qualified data that were not included in the risk assessment. As stated in
the MCP Phase II CSA Report (BBL, 2000a), for several analytes in various media the
majority of the data were J-qualified. Often these values were not incorporated into the
risk characterization. Whether this resulted in an underestimate of risk relative to those
calculated if the qualified data were used cannot be determined. However, given the
nature of these data, there is only a low probability that risks were not appropriately
quantified and the impact of eliminating them on cumulative risk estimates is minor.
Regardless, based on information presented in the previously mentioned reports, it has
been determined that planning, implementation and document procedures completed
during response actions resulted in a quality data set. Examples of the procedures
used to minimize uncertainty are presented as follows:
•
Written work plans were developed prior to conducting field sampling events,
including identification of standard operating procedures (including step-by-step
sample collection, handling and documentation procedures) and quality assurance/
quality control (QA/QC) procedures (including, generally, identification of
appropriate analytical methods, collection frequency for QA/QC samples and
required reporting limits).
•
Soil and groundwater sample collection methods, sample locations, sample depths
and analytical parameter groups were scoped using published guidance and
professional experience related to site investigation procedures, published
information related to environmental fate and transport of site-specific oil and/or
hazardous materials, site-specific historical information, and laboratory data from
previous sampling events.
•
Field personnel developed detailed documentation of field events, including
documentation of daily activities in a field logbook, as well as documentation of soil
and groundwater conditions (e.g. geology, visual observation of site-related
impacts and field parameters, such as photoionization readings and groundwater
quality parameters).
•
Field sampling was performed consistent with appropriate procedures and
applicable Massachusetts guidance documents that were publicly available at the
time of sampling.

•
Chain-of-custody forms and handling procedures were used consistently with
sample shipments from the site to the laboratory.
•
Massachusetts-certified and/or National Environmental Laboratory Accreditation
Program- (NELAP-) accredited laboratories were used for analysis of field
samples.
•
Data summary tables were prepared using laboratory electronic data deliverables
or other electronic files.
•
Unvalidated analytical data were not included in the risk assessment.
Although not resulting in a significant risk, exposure to the general worker to indoor air
was based on modeled air concentrations. There are no current indoor air receptors,
so this is not considered a significant risk.
3.7 Unrepresentative Data
Section 6.8 of the REDUA Policy indicates that a Representativeness Evaluation
should identify information generated during the response actions that was not used to
support the RAO because it was determined to be unrepresentative or no longer
representative of disposal site conditions.
All laboratory data were used and considered during site characterization for the Phase
II evaluation. No data were thrown out or disregarded. For the RAO, the pre-injection
soil data in the target area (hot spot) data were not included in concentration averages
used in the re-assessment of site risks (pers. com., BBL memo to Roy Hart, Solutia,
November 13, 2006) second risk assessment (Attachment 2), because soil
concentrations were reduced following remediation and were not representative of
current site conditions. However, when the original soil are included in the average, the
average soil concentrations are lower than that used on the November 11, 2006 reassessment of risk and reported in the Phase V completion statement (BBLES
ARCADIS, 2006b).

4. Data Usability Assessment
Consistent with the Policy, this REDUA comprises two assessment components:
•
•
analytical data assessment
field assessment
As described in Section 7.0 of the REDUA Policy, the analytical data assessment is
conducted to determine “whether analytical data are scientifically valid and defensible,
and of a sufficient level of precision, accuracy and sensitivity to support the RAO.” As
described in Section 7.2 of the Policy, a field assessment is conducted to determine
whether appropriate sampling procedures are followed, resulting in usable data. These
two components of the REDUA are presented in Sections 4.1 and 4.2, respectively.
4.1 Analytical Data Usability Assessment
4.1.1 CAM-Compliant Data
Soil and groundwater sample data used to support the Final Semi-Annual Phase V
Operation, Maintenance, and Monitoring Report and Completion Statement (BBLES
ARCADIS, 2006b) (Phase V) meet the requirements for CAM compliance and are
presented in Table 1.
4.1.1.1 CAM-Compliant Data Evaluation Criteria
Because CAM-compliant data have achieved, by definition, “presumptive certainty”
(i.e., precision, accuracy and sensitivity have been adequately determined through
adherence to CAM procedures), the REDUA Policy indicates that a limited assessment
of data usability is needed for these types of data (Section 7.1.1 of the REDUA Policy).
As a result, the assessment of CAM-compliant data included a review of laboratory
case narratives, and assessments of laboratory method blanks and laboratory
reporting limits, consistent with the REDUA Policy.
4.1.1.2 Evaluation of CAM-Compliant Data
A review of the CAM-compliant data determined that:

No issues identified in the case narratives resulted in an unacceptable level of
uncertainty.

•
Method blank data were nondetect.
•
Reporting limits were below applicable MCP Reportable Concentrations and/or
Method 1/Method 2 standards (effective February 14, 2008).
The assessment of the CAM-compliant data, on which the above findings are based, is
detailed in Table 1.
4.1.2 Pre-CAM and Non-CAM Data
Soil and groundwater sample data used to support the MCP Phase II CSA Report
(BBL, 2000a) meet the requirements for pre-CAM and non-CAM compliance, and are
presented in Table 2.
Based on Section 7.1.2 of the REDUA Policy, the pre-CAM and non-CAM data
assessment includes a quantitative assessment of the following review elements, when
available: laboratory case narratives; instrument calibrations; internal standards;
method blanks; laboratory control samples (LCSs) and laboratory control sample
duplicates (LCSDs); matrix spikes (MSs) and matrix spike duplicates (MSDs);
surrogate recoveries (organics), fractionation check standards (extractable petroleum
hydrocarbons) and interference checks (metals); laboratory reporting limits; and
laboratory analytical methods.
4.1.2.1 Evaluation of Pre-CAM and Non-CAM-Compliant Data
An assessment of the data based on the above parameters resulted in the findings
detailed in Table 2. Unless used only for field screening purposes, all data (except for
data from the August 1997 field event) were validated. Overall, the validation results
and this REDUA indicate that samples were analyzed using appropriate procedures
and state-of-the-art methods at the time the samples were collected and the data were
generated. None of the assessment findings affect the overall quality of the dataset.
The REDUA for pre-CAM and non-CAM data (based on the assessment presented in
Table 2) is summarized below:
•
Appropriate analytical methods were used (i.e., either methods identified in the
CAM, methods that are earlier versions of those identified in the CAM, or
specialized methods used to achieve site-specific objectives (i.e., USEPA SW-846

Method 8015, used to analyze diesel-range organics [DROs] and gasoline-range
organics [GROs], and Method 9060, used to analyze total organic carbon [TOC]).
•
Certain data were qualified as estimated (i.e., J-qualified) due to recoveries outside
QC limits based on data validation determinations. However, estimation of data
does not affect the usability of the results for its intended uses.
•
Some constituents were detected in some method blanks, rinse blanks and/or trip
blanks at low levels. For data that underwent validation, adjustments were made to
certain data to correct for the presence of the detected constituents. Although
these detections could indicate low-level laboratory and/or field contamination, the
levels observed do not affect usability of the data (results in potential
overestimation of constituent).
•
Certain data packages from sampling rounds used for screening purposes were
not validated; these data results are used to show consistency in the data sets.
•
In most cases, full Level IV CLP-like validated data packages were available for
review. However, not all data review elements were available within laboratory
data packages (e.g., calibration and tune data were not included in some of the
laboratory packages). However, the most commonly evaluated parameters (i.e.,
those parameters most often used to support data quality, such as surrogates,
method blanks, rinse/trip blanks, MS/MSD and LCS/LCSD) were available and
within control limits unless otherwise stated in Table 2. Therefore, because the
parameters available for review were consistently of acceptable quality, the quality
of these data is considered usable regardless of the lack of calibration data.
•
Some data packages contained nondetect results for constituents in which the
identified reporting limits (RLs)1 are above MCP RCS-2 or RCGW-2 reportable
concentrations. In most cases, the detection limits were unavoidably elevated due
to laboratory dilutions of certain samples exhibiting visual/olfactory characteristics
and were performed to protect the analytical instruments from damage.
Additionally, the nondetect results with elevated reporting limits are typically
associated with constituents that are not COCs related to the site.
•
Laboratory data packages for SB-79, SB-80 and SB-81 (three of the eight soil
borings collected in April 1997) were not available as part of this REDUA and

The RL is the lowest detection limit achievable by the laboratory instrument/equipment.

therefore could not be reviewed. However, laboratory data for the remainder of this
sampling group (i.e., SB-72, SB-73, SB-74, SB-77 and SB-78) were available,
reviewed and validated, and were determined to be of sufficient quality. In addition,
data for the three borings are consistent with other site data collected during the
MCP response action process with respect to concentration and detected
constituent groups. As such, this data is considered usable.
4.2 Field Quality Control Assessment
Field QC procedures were established and the field investigations were conducted
consistent with procedures described in the Baseline Environmental Assessment
Scope of Work (BEA SOW; Blasland, Bouck and Lee, Inc. [BBL], 1996) and the BEA
SOW Field Sampling Plan (BBL, 1997).
As identified in Table 3 of the MassDEP Policy, this field QC assessment includes the
following review elements: confirmation that appropriate sampling procedures were
used; appropriate sample containers and preservatives were used; samples were
analyzed within acceptable holding time limits; and the number of field duplicates, rinse
blanks, MS/MSDs and trip blanks collected per sample delivery group is
commensurate with CAM requirements and/or investigation-specific goals. In addition,
the data were assessed to determine that appropriate sample handling and shipment
procedures were followed, and that chain-of-custody forms were used and completed
accurately.
The field QC assessment determined that, overall:
•
Field procedures used during site investigations were performed consistent with
the plans identified above and were appropriate at the time they were collected.
•
All evaluated data were analyzed within acceptable holding time limits with the
exception of SB-138, which was analyzed one day over the method-specific hold
time. Validation of the data resulted in the “J” qualification (estimation) of the
results for this sample. The results for this sample are similar to results for other
data that are of acceptable quality. Therefore, these data are considered usable.
•
Appropriate sample containers and preservatives were used.
•
Number of field QA/QC samples collected (on a per-sampling-event basis) meet or
exceed CAM requirements and are consistent with investigation-specific goals.

5. Rejection of Analytical Data
No data quality indicators assessed as part of the CAM, pre-CAM and non-CAM
REDUA (Tables 1 and 2) meet the “gross failure” criteria provided in Appendix IV of the
Policy (resulting in rejection of data). Criteria that would lead to the rejection of data
include holding times greater than two times the allowable limit, sediment/soil samples
without methanol or water preservation (volatile petroleum hydrocarbons [VPHs] and
VOCs only), and/or LCS and LCSD recoveries, surrogate recoveries or MS and MSD
recoveries less than 10 percent and/or laboratory-specified rejection criteria.
There were two holding time violations, as listed above, which do not meet the “gross
failure” criteria. All surrogate recoveries and MS/MSD recoveries passed acceptance
criteria. As additional support for data usability, data quality indicators did not fail
vendor-specific control limits to a degree that would cause rejection of data, as
documented in Tables 1 and 2. As a result, no data were determined to be gross
failures.

6. Summary
The information summarized in this REDUA indicates that site data were collected and
analyzed using appropriate bases for characterizing the site including, but not limited
to, appropriate sample distribution, analytes, methods and QA/QC procedures. As
described in Section 3.6, many factors have contributed to compiling a quality dataset
including, but not limited to, collection of data by qualified personnel, analysis of
samples by reputable/certified laboratories and development of and adherence to
written field sampling and QA plans. As a result, the dataset adequately characterizes
the nature and extent of site-related OHM and provides an adequate number of
samples from within the site to accurately represent potential exposure points/exposure
point concentrations. Further, samples within areas subject to remediation were
collected at locations and depths that provided for accurate and precise selection of
excavation limits. In summary, the data are usable, representative of site conditions
and are of acceptable quality for supporting the RAO.

(a). Well MW-83S - the reporting limit for styrene (0.25U) is greater than the MCP
standard (0.1). Well 87S - the reporting limits for styrene and vinyl chloride (1U and
2U) are greater than the MCP standard (0.1 and 0.002, respectively). Well MW93A - the reporting limit for styrene (0.1U) equals the MCP standard ((0.1). Wells
MW-93B and MW-95S - the reporting limit for vinyl chloride (0.01U) is greater than
the MCP standard (0.002). Well MW-94S - the reporting limit for vinyl chloride
(0.02U) is greater than the MCP standard.
(b). Acetone was detected in the method blank and has been qualified as
undetected in sample MW-86S.
(c). With the exception of sample MW94S, no chains of custody were included in
the data package.
(d). Compounds in the C9-C18 range were detected in the EPH method blank, the
reported sample has been corrected for blank content.
(e). No EPH initial calibration standards were included in the data package.
(f). Continuing calibration standards were outside RPD limit, therefore methyl-tertbutyl-ether in sample MW94S has been qualified as estimated with the potential for
false negatives.
(a). Methylene chloride was detected in the trip blank and has been qualified as
undetected in samples MW-26S, MW-25D, MW-28D, MW-43D and MW-53D .
(b). Only MW-85S in this SDG is part of the FGHA and it is a background location.
(a). Samples used for screening purposes only.
Results only for screening purposes from Univ. of Connecticut lab.

Notes:
2. Data was validated by Blasland, Bouck and Lee of Syracuse, NY for the Phase II Comprehensive Site Assessment Report, February 2000.
3. Data was validated by Blasland, Bouck and Lee of Syracuse, NY for the Final Semi-Annual Phase V Operation, Maintenance, and Monitoring Report and Completion Statement, August 2006.
4. Constituents detected in rinse blanks and trip blanks (i.e., "blank contamination") may indicate that reported sample data for these constituents are overestimated. That is, actual field concentrations may be less than reported by the laboratory. If validated, associated sample concentrations would either remain unqualified or be qualified as not detected (U-qualified).
5. Per the Baseline Environmental Assessment Scope of Work, Blasland, Bouck and Lee, Inc. (BBL) 1997, appropriate sample containers were utilized.
6. Per the Phase II Comprehensive Site Assessment Scope of Work (Atlantic Environmental Services , 1996), appropriate containers were supplied by the laboratory based on analysis being performed depending on the sample result and level of blank contamination

Former VC Gas Holder Area
Post-Remediation Addendum to
MCP Phase II Risk Assessment
Solutia Inc. Indian Orchard Plant
As reported previously, underground utilities are present near the treatment area of the Former Vinyl
Chloride Gas Holder Area (FGHA) at the Indian Orchard Plant in Springfield, Massachusetts (Blasland,
Bouck & Lee, Inc. [BBL], 2000) (BBL, 2003). These underground utilities may need repairs and/or new
underground utilities may need to be installed. BBL completed this supplemental risk characterization
and obtained a Licensed Site Professional- (LSP-) of-record opinion for utility repair that may extend
beyond the assumptions presented in the original risk assessment for post-remediation conditions.
Based on the risk assessment completed by BBL in 2000, a condition of No Significant Risk (NSR) of
harm to human health was demonstrated for a utility worker in the FGHA, assuming one 8-hour day of
excavation per year for 25 years (BBL, 2000). NSR was determined assuming an exposure point
concentration (EPC) for vinyl chloride (VC) of 490 milligrams per kilogram (mg/kg), the maximum
concentration detected within the source area of the FGHA consistent with the requirements of the MCP
40.0926(3)(b)(2). In the risk assessment completed in 2000, it was conservatively assumed that 100% of
utility activity would occur in the FGHA source area.
The default MADEP-recommended value for the duration of a utility worker exposure scenario is one 8hour work day for one event per year. This is the value that was appropriately used in the risk assessment
presented in the MCP Phase II Comprehensive Site Assessment (BBL, 2000). However, it is possible that
a utility worker could be working within the aerial extent of the treatment area (previously the source
area) at the FGHA for an extended period, possibly for 3 to 5 days. Therefore, BBL has re-evaluated risks
for a 5-day period, as well as determined the maximum acceptable duration for a utility worker, using
post-remediation data. In this reassessment, it is assumed that the exposure frequency for groundwater
remained at one day per year, consistent with the exposure assessment in the 2000 risk assessment. This
assumption states that although direct contact with groundwater may occur, it is assumed that the
exposure “would be experienced only occasionally by laborers repairing pumps used to dewater
excavation holes, an activity that would result in an acute exposure.”
In addition to the expected change in exposure duration by the utility worker, remedial activities at the
site have resulted in an overall decrease in the VC concentration in the FGHA. The maximum
concentration of VC detected in soil in 1997 was 490 ppm, with a frequency of detection of 13 of 28.
Evaluation of the data according to Massachusetts Contingency Plan (MCP) requirements indicated that

the EPC should be a conservative estimate of the site average (40.0926(3)(b)(2)). Therefore, the
maximum concentration was used to determine risk for the site in completing the original site assessment
(BBL, 2000). More recent data show a frequency of detection of 17/73 and an average of 108 parts per
million (ppm) (BBLES, 2006). Evaluation of the more recent soil data (per MCP 40.0926(3)(b)(2))
indicates that a simple arithmetic average adequately represents the soil data. This is because 75% of the
data points used in the averaging are less than the average concentration and no data point used is greater
than 10 times the resulting average (BBLES, 2006) (Massachusetts Department of Environmental
Protection [MADEP], 2006).
Post-remediation groundwater monitoring in the FGHA shows a decrease in constituent concentrations
(BBLES, 2006). As a result, the EPCs have been modified to reflect the most current data collected in
2006 (BBLES, 2006). Review of the groundwater data (1986 through to 2006) indicated that several
compounds not detected prior to early 1999 (when the initial risk assessment was completed) were
detected in groundwater at low concentrations. These data are evaluated for frequency and magnitude of
detection for this amended risk assessment (Table 1). Any data detected at a frequency of less than 10%
and at concentration not exceeding the applicable GW Method 1 Standards were eliminated from further
consideration. For the remaining compounds, the maximum concentrations from 2006 were used as the
EPC concentrations (Table 1). Ambient air concentrations were calculated as described in Section 7.3.3.2
of the original risk characterization (BBL, 2000) and are presented in Table 1 of this memo.

In the initial site assessment, the construction worker’s cumulative cancer risk attributable to exposure to
VC in subsurface soil was the only exposure that exceeded the criteria of a cumulative cancer risk
threshold of 1 in 100,000 (1E-05), set forth at 310 CMR 40.0993(7). As a result, in addition to
reassessing the utility worker risks, cancer and noncancer risks posed to the construction worker were also
reassessed. This new evaluation of risk at the FGHA includes the use of the more recent data (arithmetic
average of 108 ppm for VC), any revised toxicity values since 2000, and any modified default exposure
assumptions. Table 2 is an excerpt from the original risk assessment document, with the revised exposure
assumptions are highlighted and bolded. Table 3 outlines the toxicity factors that were modified to reflect
the values currently available from the MADEP (http://www.mass.gov/dep/service/compliance/

mg/day = milligrams per day.
cm2/day = square centimeters per day.

mg/cm = milligrams per square centimeter.
μg/m3 = micrograms per cubic meter.
m3/hr = cubic meters per hour.
kg = kilogram.
Using the assumptions outlined in Table 2, the reassessment of risk resulted in NSR of harm to human
health based on the criteria of a cumulative cancer risk threshold of 1 in 100,000 (1E-05) and a
cumulative noncancer hazard index equal to one, set forth at 310 CMR 40.0993(7) for both the utility
worker and construction worker. The revised cancer risks for soil for the utility worker and the
construction worker were 2.5E-06 and 2.6E-06, respectively. The revised noncancer hazards from soil for
the utility and construction workers were 8E-03 and 4E-01, respectively. The revised groundwater cancer
and noncancer risks for the utility worker were 1.5E-06 and 6E-03, respectively. As a result, the total
(groundwater plus soil) cancer and noncancer risks posed to the utility worker at the FGHA is 3.9E-06
and 1E-02, respectively (Table 4). These values assume a maximum exposure frequency for the utility
worker of 5 days per year for soil, and 1 day per year for groundwater.
If a utility worker is assumed to be actively repairing utilities in the FGHA for a maximum exposure
duration of 20 days per year, the resulting cancer risk is 9.8E-06 for soil and 1.5E-06 for groundwater (the
exposure frequency for groundwater is assumed to be no greater than 1 event per day). The noncancer
hazards are 3E-02 and 6E-03 for soil and groundwater, respectively. The resulting total cancer and
noncancer risks are 1.1E-05 and 4E-02, respectively. These values are less than or essentially equal to the
criteria of NSR established by 310 CMR 40.0993(7) (a cumulative cancer risk threshold of 1 in 100,000
(1E-05) and a cumulative noncancer hazard index equal to one). As a result, a utility worker exposed to
site conditions as described, for 20 days, will not be exposed to any significant increase in risk.
