Additional information for the limits in Tables A1 and A2 above.
(A)
Include when using technology-based CBOD5 limits: The CBOD5 concentration
limits are considered equivalent to the minimum design criteria for BOD5 specified
in OAR Chapter 340, Division 41.
(B)
Average dry weather design flow to the facility equals XX MGD15. Mass load limits16 are based on XX MGD.
(C)
Mass load limits for older facilities are supposed to be based on the Design Average Wet Weather Flow (AWWF). In the case of some older facilities, they may
not be, and the AWWF may not even be known. If this is the case and the permittee is requesting new AWWF-based mass load limits for wintertime flows, include
the following: In accordance with OAR 340-041-0061(9)(d), the mass load limits
are interim limits. Within 12 months of permit issuance, the permittee must submit

to DEQ the design average wet weather flow and hydraulic secondary treatment
capacity. Upon review and approval of the design flow information, DEQ may
modify the permit and include final mass load limits as described in OAR 340041-0061(a).
(D)
b.
If summer period concentration limits are higher than the basin’s minimum design
criteria, include17:In accordance with OAR 340-041-0061(3)(c), compliance with
the more stringent minimum design criteria that apply to this basin in the summer
period will be deferred until it is necessary to expand or otherwise modify or replace the existing treatment facilities.
Additional Parameters.
Permittee must comply with the limits in the following table (year-round except as noted):
Table A3: Limits for Additional Parameters
Year-round
(except as noted)
BOD5 or CBOD5 and TSS
Removal Efficiency
Limits (bacteria limits assume no bacteria TMDL in
place)
May not be less than 85% monthly average for BOD5 or CBOD5
and TSS. With systems where preliminary treatment occurs in
septic tanks, such as STEP systems, include reference to Note a.
Regarding the 85% removal, this can be reduced for lagoons,
trickling filters and when influent is less concentrated. See 40 CFR
133.103.
Include the following for dischargers with TMDL temperature WLAs(Waste Load Allocations):
Temperature
Expressed as (choose one): Maximum 7 day rolling average ETL or
Daily Maximum ETL (Excess Thermal Load)
Effluent Flow (for permittees
Daily Maximum
who have elected to build
storage capacity to reduce

Include the following for discharges to freshwater and estuarine waters other than shellfish growing
waters:
E. coli Bacteria (see Note b.)
Monthly log mean (same as geometric mean18) may not exceed 126
organisms per 100 ml.
No single sample may exceed 406 organisms per 100 ml.
Include the following for discharges to marine and estuarine shellfish growing waters (for help in
delineating, refer to Bacteria IMD):
Fecal Coliform Bacteria
Monthly Median concentration may not exceed 14 organisms per
100 ml.
No more than 10% of the samples collected in a calendar month
may exceed 43 organisms per 100 ml.
Include the following for discharges to coastal areas with primary contact recreation uses (for help,
refer to Bacteria IMD):
Enterococcus Bacteria
Monthly geometric mean may not exceed 35 organisms per 100 ml.

Year-round
(except as noted)
Chlorine, Total Residual20
Limits (bacteria limits assume no bacteria TMDL in
place)
If compliance is to be established with respect to continuous
monitoring:
May not be outside the range of XX to XX for more than a total of
7 hours and 2619 minutes in any calendar month, and no individual
excursion from this range may exceed 60 minutes.
The monthly average effluent concentration limit is XX mg/L.
The daily maximum effluent concentration limit is XX mg/L.
Include if applicable:
DEQ has established a minimum Quantitation Limit of 0.05 mg/L21
for Total Residual Chlorine. In cases where the monthly average or
daily maximum limit for Total Residual Chlorine is lower than the
Quantitation Limit, DEQ will use the reported Quantitation Limit
as the compliance evaluation level.
Other limits
Example: ammonia. Note: limits should be expressed in
concentration and mass whenever possible22. Exceptions include
those parameters which are neither conservative nor bioaccumulative. Ammonia again is an example: it oxidizes rapidly into nitrate
and so cumulative effectives outside the mixing zone are not a
concern.
Notes: (update lettering as necessary)
a. Include the following with systems where preliminary treatment occurs in septic tanks, such
as STEP systems: Due to preliminary treatment that occurs within the septic tanks, the influent BOD5 and TSS concentrations are assumed to be 200 mg/L for calculation of the percent
removal efficiency. 23
b. No single E. coli sample may exceed 406 organisms per 100 mL; however, DEQ will not cite
a violation of this limit if the permittee takes at least 5 consecutive re-samples at 4 hour intervals beginning within 28 hours after the original sample was taken and the geometric
mean of the 5 re-samples is less than or equal to 126 E. coli organisms/100 mL. 24
2.
Regulatory Mixing Zone
[Include if there is no mixing zone] There is no regulatory mixing zone for this discharge25.
[Include if there is a mixing zone] Pursuant to OAR 340-041-0053, the permittee is granted a regulatory
mixing zone as described below:
[Insert mixing zone description. Note: if current description contains the phrase “shall be defined
as”, replace with “is”].
3.
Groundwater Protection
The permittee may not conduct any activities that could cause an adverse impact on existing or potential
beneficial uses of groundwater. All wastewater and process related residuals must be managed and disNPDES permit template version 2.1 10/01/2015

posed of in a manner that will prevent a violation of the Groundwater Quality Protection Rules (OAR
Chapter 340, Division 40).
4.
Use of Recycled Water
The permittee is authorized to distribute recycled water if it is:
a.
Treated and used according to the criteria listed in Table A426.
b.
Managed in accordance with its DEQ-approved Recycled Water Use Plan27 unless exempt as provided in Schedule D, condition 5?.
c.
Used in a manner and applied at a rate that does not have the potential to adversely impact
groundwater quality28.
d.
Applied at a rate and in accordance with site management practices that ensure continued agricultural, horticultural, or silvicultural production and does not reduce the productivity of the site29.
e.
Irrigated using sound irrigation practices to prevent:
i.
Offsite surface runoff or subsurface drainage through drainage tile;
ii.
Creation of odors, fly and mosquito breeding, or other nuisance conditions; and
iii.
Overloading of land with nutrients, organics, or other pollutants30.
Earlier versions of the permit template directed the permit writer to delete rows in Table A4 pertaining to higher classes of treated water than the permittee can achieve, on the grounds that failure to do
could make determining compliance on DMRs difficult. Permit writers are now advised to leave any type
of treatment in the permit that has a reasonable likelihood of being employed during the permit cycle, so as
to preclude the need for a permit modification if the permittee decides to change their level of treatment.

Mercury Minimization Plan
By the end of the twenty fourth month [timeframe is at discretion writer but must not exceed 24 months]
after permit issuance, the permittee must submit an MMP (Mercury Minimization Plan) for approval. At a
minimum, the MMP must include the following:
a.
Identification and evaluation of current and potential mercury (both MeHg and total) sources
b.
Identification and evaluation of conditions (i.e., anaerobic conditions) that might contribute to the
methylation of elemental mercury in the collection and treatment systems
c.
Identification of industrial, commercial and residential sources of mercury
d.
A monitoring plan to confirm current or potential sources of mercury (Monitoring Plan)
e.
Identification of potential methods for reducing or eliminating mercury. These may include but are
not limited to:
f.
i.
BMP requirements or limits for industrial and commercial sources of mercury to a collection system
ii.
Material substitution
iii.
Material recovery
iv.
Spill control and collection
v.
Waste recycling
vi.
Process modifications
vii.
Laboratory housekeeping, use and disposal practices and
viii.
Public education.
Ongoing monitoring of effluent to enable evaluation of the effectiveness and implementation of the
MMP.
Before approving the plan, DEQ will put the plan out on public notice for 30 days. The permittee
must begin implementation of the plan within one month of DEQ’s approval. If DEQ determines
that the MMP is not effective at reducing sources of mercury from entering its collection system, or
if a water column translation of the fish tissue criterion is developed, DEQ may reopen the permit
to modify the permit conditions. These modifications may include but are not limited to the addition of a numeric effluent limit.

136 and 40 CFR 503 for biosolids or other approved procedures as per Schedule F.
Detection and Quantitation Limits
i.
Detection Level (DL) – The DL is defined as the minimum measured concentration of a
substance that can be distinguished from method blank results with 99% confidence. The
DL is derived using the procedure in 40 CFR Part 136 Appendix B and evaluated for reasonableness relative to method blank concentrations to ensure results reported above the
DL are not a result of routine background contamination. The DL is also known as the
Method Detection Limit (MDL) or Limit of Detection (LOD).
ii.
Quantitation Limits (QLs)50 – The QL is the minimum level, concentration or quantity of a
target analyte that can be reported with a specified degree of confidence. It is the lowest
level at which the entire analytical system gives a recognizable signal and acceptable calibration for the analyte. It is normally equivalent to the concentration of the lowest calibration standard adjusted for sample weights, volumes, preparation and cleanup procedures
employed. The QL as reported by a laboratory is also sometimes referred to as the Method
Reporting Limit (MRL) or Limit of Quantitation (LOQ).
iii.
For compliance and characterization purposes, the maximum acceptable QL is stated in
this permit.
Implementation
i.
The Laboratory QLs (adjusted for any dilutions) for analyses performed to demonstrate
compliance with permit limits or as part of effluent characterization, must be at or below
the QLs specified in the permit unless one of the conditions below is met.

d.
e.
(A)
The monitoring result shows a detect above the laboratory reported QL.
(B)
The monitoring result indicates nondetect at a DL which is less than the QL.
(C)
Matrix effects are present that prevent the attainment of QLs51, 52 and these matrix
effects are demonstrated according to procedures described in EPA’s “Solutions to
Analytical Chemistry Problems with Clean Water Act Methods”, March 2007. If
using alternative methods and taking appropriate steps to eliminate matrix effects
does not eliminate the matrix problems, DEQ may authorize re-sampling or allow
a higher QL to be reported. In the case of effluent characterization monitoring,
DEQ may allow the re-sampling to be done as part of Tier 2 monitoring. Sections
B.5? and B.6? contain more information on Tier 1 and Tier 2 monitoring.
Laboratory Quality Assurance and Quality Control
i.
Laboratory Quality Assurance and Quality Control (QA/QC) – The permittee must develop
and implement a written QA/QC program that conforms to the requirements of 40 CFR
Part 136.7.
ii.
If QA/QC requirements are not met for any analysis and the sample results are deemed invalid, the permittee must re-analyze the sample. If the sample cannot be re-analyzed, the
permittee must re-sample and analyze at the earliest opportunity. If a sample does not meet
QA/QC requirements, the permittee must include the result in the discharge monitoring report (DMR) along with a notation (data qualifier) explaining how it does not meet QA/QC
requirements, but the permittee must not use the result in any calculation required by the
permit unless authorized by DEQ.
Reporting Sample Results - The permittee must follow the procedures listed below when reporting
sampling results.
i.
The permittee must report the laboratory DL and QL as defined above for each analyte,
with the following exceptions: pH, temperature, BOD, CBOD, TSS, O&G, hardness, alkalinity, bacteriological analytes and nitrate-nitrite. For temperature and pH, neither the QL
nor the DL need to be reported. For the other parameters, the permittee is only required to
report the QL and only when the result is ND.
ii.
The permittee must report the same number of significant digits as the permit limit for a
given parameter53.
iii.
CAS Numbers. CAS numbers (where available) must be reported along with monitoring
results.
iv.
(for Discharge Monitoring Reports) If a sample result is above the DL but below the QL,
the permittee must report the result as the DL preceded by DEQ’s data code “e”. For example, if the DL is 1.0 µg/l, the QL is 3.0 µg/L and the result is estimated to be between
the DL and QL, the permittee must report “e1.0 µg/L” on the DMR. This requirement does
not apply in the case of parameters for which the DL does not have to be reported.
v.
(for Discharge Monitoring Reports) If the sample result is below the DL, the permittee
must report the result as less than the specified DL. For example, if the DL is 1.0 µg/L and
the result is ND, report “<1.0” on the discharge monitoring report (DMR). This requireNPDES permit template version 2.1 10/01/2015
Expiration Date:
Permit Number:
File Number:
Page 17 of 62 Pages
ment does not apply in the case of parameters for which the DL does not have to be reported.
f.
Calculating and Reporting Mass Loads
The permittee must calculate mass loads on each day the parameter is monitored using the following equation:
Example calculation: Flow (in MGD) X Concentration (in mg/L) X 8.34 = Pounds per day
2.
i.
Mass load limits all have two significant figures unless otherwise noted.
ii.
When concentration data are below the QL: To calculate the mass load from this result, use
the DL. Report the mass load as less than the calculated mass load. For example, if flow is
2 MGD and the reported sample result is <1.0 µg/L, report “<0.02 lb/day” for mass load on
the DMR (1.0 µg/L x 2 MGD x conversion factor = 0.017 lb/day, round off to 0.02 lb/day).
[This last sentence may be deleted from permit if it is included in the Permit Evaluation
Report.]
iii.
When concentration data are above the DL, but below the QL: To calculate the mass load
from this result, use the detection level. Report the mass load as the calculated mass load
preceded by “e”. For example, if flow is 2 MGD and the reported sample result is e1.0
µg/L, report “e0.02 lb/day” for mass load on the DMR (1.0 µg/L x 2 MGD x conversion
factor = 0.017 lb/day, round off to 0.02 lb/day). [This last sentence may be deleted from
permit it is included in the Permit Evaluation Report].
Influent Monitoring and Reporting Requirements
The permittee must monitor influent specify location, such as between the bar screen and the aerated grit
chamber54 and report results in accordance with the table below.

Permit Application Monitoring Requirements80
The renewal application for this permit requires 3 (permit writer may increase to 4) scans for the parameters listed in the table below. This data may be collected up to 4.5 years in advance of submittal of the renewal application. DEQ recognizes that some facilities may find it difficult to collect 3 scans that are representative of the seasonal variation in the discharge from each outfall within the permit renewal
timeframe, and is therefore requiring that this monitoring be completed as part of compliance with this
permit. Delete those parameters for which there are already effluent monitoring requirements.

Industrial User Survey
The permittee must conduct an industrial user survey to determine the presence of any industrial users discharging wastewaters subject to pretreatment and submit a report on the findings to DEQ within 24 months
of the permit effective date. The purpose of the survey is to identify whether there are any categorical industrial users discharging to the POTW, and ensure regulatory oversight of these discharges to state waNPDES permit template version 2.1 10/01/2015

ters. If the POTW has already completed a baseline IU Survey the results of this survey are to be provided
to DEQ within two months of the permit effective date.
Guidance on conducting IU Surveys can be found at
http://www.deq.state.or.us/wq/pretreatment/docs/guidance/IUSurveyGuidance.pdf
Once an initial baseline IU Survey is conducted it is to be maintained by the POTW and made available for
inspection by DEQ. Every 5 years from the effective date of the permit, the permittee must submit an updated IU survey.

SCHEDULE E: PRETREATMENT ACTIVITIES
1.
Program Administration
[If new program, insert the following] The permittee must develop and submit for DEQ approval all elements of a federally equivalent Industrial Pretreatment program by insert date. The submittal must include
an industrial user survey, sewer use ordinance and any other related legal authorities required for implementation (e.g., inter-jurisdictional agreements, if applicable), a local limits technical evaluation, pretreatment procedures implementation manual and enforcement response plan. Prior to the full program submittal, the permittee must also submit a plan of study regarding the local limits technical evaluation, for review
by DEQ. Upon DEQ approval, the permittee will immediately implement the approved program. The
permittee must conduct and enforce its Pretreatment Program, as approved by DEQ, and comply with the
General Pretreatment Regulations (40 CFR part 403). The permittee must secure and maintain sufficient
resources and qualified personnel to carry out the program implementation procedures described in this
permit as required by 40 CFR § 403.8(f)(3).
2.
Legal Authorities
The permittee must adopt all legal authority necessary to fully implement its approved pretreatment program and to comply with all applicable state and federal pretreatment regulations. The permittee must also
establish, where necessary, contracts or agreements with contributing jurisdictions to ensure compliance
with pretreatment requirements by industrial users within these jurisdictions. These contracts or agreements
must identify the agency responsible for all implementation and enforcement activities to be performed in
the contributing jurisdictions. Regardless of jurisdictional situation, the permittee is responsible for ensuring that all aspects of the pretreatment program are fully implemented and enforced.
3.
Industrial User Survey
[If new program, insert the following]The permittee must conduct a baseline Industrial User Survey and
submit results of the survey to DEQ by insert date. The permittee must update its inventory of industrial
users at a frequency and diligence adequate to ensure proper identification of industrial users subject to pretreatment standards, but no less than once per year. The permittee must notify these industrial users of applicable pretreatment standards in accordance with 40 CFR § 403.8(f)(2)(iii). Survey update procedures
must ensure that IUs potentially subject to pretreatment are identified and issued a control mechanism, if
required, on a timely basis but no later than 6 months after receipt of information indicating the IU is subject to pretreatment.
4.
National Pretreatment Standards
[If new program, insert the following]The permittee must conduct a technical evaluation of the need to develop local limits and either develop local limits or demonstrate that local limits are not necessary by date.
Prior to conducting the local limits evaluation, the permittee must submit a plan of study for the local limits
evaluation for review by DEQ. The permittee must enforce categorical pretreatment standards promulgated
pursuant to section 307(b) and (c) of the Clean Water Act, prohibited discharge standards as set forth in 40
CFR § 403.5(a) and (b), or local limits developed by the permittee in accordance with 40 CFR § 403.5(c),
whichever are more stringent, or are applicable to any non-domestic source regulated under section 307(b),
(c), or (d) of the Act.

5.
Local Limits
The permittee must perform a technical evaluation of the need to revise local limits within 18 months after
permit re-issuance unless DEQ authorizes or requires, in writing, an alternate time frame115. Locally derived discharge limits must be defined as pretreatment standards under section 307(d) of the Act and must
conform to 40 CFR § 403.5(c) and § 403.8(f)(4). Technically based local limits must be developed in accordance with the procedures established by DEQ and the EPA’s Local Limits Guidance.
6.
Control Mechanisms
The permittee must issue an individual control mechanism to all Significant Industrial Users except where
the permittee may, at its discretion, issue a general control mechanism as defined by 40 CFR
§ 403.8(f)(1)(iii); or certification in lieu of a control mechanism for Non-Significant Categorical Industrial
Users (NSCIUs) as defined by 40 CFR § 403.3(v)(2), and Non-Discharging Categorical Industrial Users
(NDCIUs). All individual and general control mechanisms must be enforceable and contain, at a minimum,
the requirements identified in 40 CFR § 403.8(f)(1)(iii)(B); and, may contain equivalent concentration and
mass based effluent limits where appropriate under 40 CFR § 403.6(c)(5) and (6). Unless a more stringent
definition has been adopted by the permittee, the definition of Significant Industrial User must be as stated
in 40 CFR § 403.3(v).
7.
Compliance Monitoring
a.
Industrial User Sampling and Inspection
The permittee must randomly sample and analyze the effluent from Industrial Users at a frequency
commensurate with the character, consistency, and volume of the discharge and conduct surveillance activities in order to identify, independent of information supplied by Industrial Users, occasional and continuing noncompliance with Pretreatment Standards. The permittee must conduct a
complete facility inspection; and, sample the effluent from each Significant Industrial User at least
once a year at a minimum, unless otherwise specified below:
i.
Where the permittee has authorized the Industrial User subject to a categorical Pretreatment Standard to forego sampling of a pollutant regulated by a categorical Pretreatment
Standard in accordance with 40 CFR § 403.12(e)(2), the permittee must sample for the
waived pollutant(s) at least once during the term of the Categorical Industrial User's control
mechanism. In the event that the permittee subsequently determines that a waived pollutant
is present or is expected to be present in the Industrial User's wastewater based on changes
that occur in the User's operations, the permittee must immediately begin at least annual effluent monitoring of the User's Discharge and inspection.
ii.
Where the permittee has determined that an Industrial User meets the criteria for classification as a Non-Significant Categorical Industrial User, the permittee must evaluate, at least
once per year, whether an Industrial User continues to meet the criteria in 40 CFR §
403.3(v)(2).
iii.
In the case of Industrial Users subject to reduced reporting requirements under 40 CFR §
403.12(e)(3), the permittee must randomly sample and analyze the effluent from Industrial
Users and conduct inspections at least once every two years. If the Industrial User no longer meets the conditions for reduced reporting in 40 CFR § 403.12(e)(3), the permittee must
immediately begin sampling and inspecting the Industrial User at least once a year.

b.
Industrial User Self Monitoring and Other Reports
The permittee must receive and analyze self-monitoring and other reports submitted by industrial
users as required by 40 CFR § 403.8(f)(2)(iv) and § 403.12(b),(d),(e),(g) and (h). Significant Industrial User reports must include Best Management Practice (BMP) compliance information per 40
CFR § 403.12(b), (e), (h), where appropriate.
c.
Industrial User Monitoring in Lieu of Self-Monitoring
Where the permittee elects to conduct monitoring of an industrial user in lieu of requiring selfmonitoring, the permittee must gather all information which would otherwise have been submitted
by the user. The permittee must also perform the sampling and analyses in accordance with the protocols established for the user and must follow the requirements in 40 CFR § 403.12(g)(2) if repeat
sampling is required as the result of any sampling violation(s).
d.
Sample Collection and Analysis
Sample collection and analysis, and the gathering of other compliance data, must be performed
with sufficient care to produce evidence admissible in enforcement proceedings or in judicial actions. Unless specified otherwise by the Director in writing, all sampling and analyses must be performed in accordance with 40 CFR part 136 or 40 CFR part 503 for biosolids analytes.
8.
Slug Control Plans
The permittee must evaluate whether each Significant Industrial User needs a slug control plan or other action to control slug discharges. Industrial Users identified as significant after October 14, 2005, must be
evaluated within 1 year of being designated a Significant Industrial User. A slug discharge is any discharge
of a non-routine, episodic nature, including but not limited to an accidental spill or a non-customary batch
discharge that has a reasonable potential to cause interference or pass through or in any other way violate
the permittee’s regulations, local limits, or conditions of this permit. Per 40 CFR Part 403:8(f)(2)(vi), the
permittee is required to track and document any slug discharge by Significant Industrial Users and make it
available to DEQ upon request. The permittee must require Significant Industrial Users to immediately
notify the permittee of any changes at its facility affecting potential for a slug discharge. If the permittee
determines that a slug control plan is needed, the requirements to control slug discharges must be incorporated into the Significant Industrial User’s control mechanism and the slug plan must contain, at a minimum, the following elements:

Procedures for immediately notifying the permittee of slug discharges, including any discharge that
would violate a prohibition under 40 CFR § 403.5(b) with procedures for follow-up written notification within five days; and
d.
If necessary, procedures to prevent adverse impact from accidental spills, including inspection and
maintenance of storage areas, handling and transfer of materials, loading and unloading operations,
control of plant site run-off, worker training, building of containment structures or equipment,
measures for containing toxic organic pollutants (including solvents), and/or measures and equipment for emergency response.
Enforcement
The permittee must identify all violations of the industrial user's permit or local ordinance. The permittee
must investigate all such instances of industrial user noncompliance and take all necessary steps to return
users to compliance. The permittee’s enforcement actions must follow its approved legal authorities (for
example, ordinances) and Enforcement Response Plan developed in accordance with 40 CFR § 403.8(f)(5).
The permittee must periodically review administrative penalties to ensure that the penalties serve as an effective deterrent of noncompliance.
10.
Public Notice of Significant Noncompliance
The permittee must publish annual notification in a newspaper(s) of general circulation that provides meaningful public notice within the jurisdiction(s) served by the permittee of industrial users which, at any time
during the previous 12 months, were in significant noncompliance with applicable pretreatment requirements. For the purposes of this requirement, an industrial user is in significant noncompliance if it meets
one or more of the criteria listed in 40 CFR § 403.8(f)(2)(viii).
11.
Data and Information Management
The permittee must develop and maintain a data management system designed to track the status of the industrial user inventory, discharge characteristics, and compliance. In accordance with 40 CFR § 403.12(o),
the permittee must retain all records relating to pretreatment program activities for a minimum of 3 years
and make such records available to DEQ and EPA upon request. The permittee must also provide public
access to information considered effluent data under 40 CFR part 2.
12.
Annual Pretreatment Program Report
The permittee must submit a complete report to DEQ on or before March 31 that describes the pretreatment
program activities during the previous calendar year pursuant to 40 CFR § 403.12(i) 116. For guidance on
the content and format of this report, contact DEQ’s pretreatment coordinator. Reports submitted to DEQ
regarding pretreatment must be signed by a principal executive officer, ranking elected official or other duly authorized employee if such employee is for overall operation of the POTW117.
13.
Pretreatment Program Modifications
The permittee must submit in writing to DEQ a statement of the basis for any proposed modification of its
approved program and a description of the proposed modification in accordance with 40 CFR § 403.18. No

The lat/long for the outfall can be obtained from the Outfall Location Tool at http://deq05/wqoutfalls/EOPbasics.aspx. It may
also be obtained from the permit application or other method such as Google Maps.
2
In the past, information on the facility type has been included on the face page of the permit along with the facility location.
Since this information can potentially trigger the need for a permit modification if the treatment technology changes, it is no
longer included. Note that even without such a description, the permit may still need to be modified as the result of a treatment
modification if the modifications mean that different TBELs (which includes basin standards) apply, or if the change(s) in
process or facility create the need for different permit conditions.
Oregon’s water quality criteria (found in OAR 340-041-0101 through 340-041-0350) are developed for specific basins
defined by the Oregon Water Resources Department (WRD). A map of these basins may be found at:
http://www.deq.state.or.us/wq/rules/div041/basinmap.pdf. The LLID tool is scheduled to be modified so that it may be used to
determine the WRD basin. Until this is complete, call GIS specialist at (503)229-6798.

If no street address is available, lat/long should be provided.

USGS subbasin names are used in TMDL development. A map of the USGS subbasins in Oregon may be found at:
http://www.deq.state.or.us/wq/assessment/usgssubbasinmap.htm. For a comparison of the USGS and WRD systems, go to
http://deq05/wq/wqpermits/Tools/BasinNamingConventions.pdf
6
Confirm that the LLID is correct and that it is a named stream. If you have to, go downstream until you find a named stream
and use that LLID. The LLID is two parts. Part 1 is the LLID of the named stream. Part 2 is the river mile (the discharge
location into a named stream or if the discharge is to an unnamed tributary, where that tributary enters a named stream). The
river mile should be updated from the LLID maps. In the past, there was a 3 rd part, which was a letter suffix. As of 10/1/2014,
the suffix should no longer be used.
7
Include treatment level as per the Wastewater System Classification Worksheet.
8
This number uniquely identifies the permit to the EPA. It is assigned by SIS. Within PCS, this number indicates the permit
type (e.g., Standard, General, Stormwater General).
9
This statement is included on the permit face to ensure that DEQ actions (e.g., permits, certifications) that affect land use are
in accordance with state land use planning goals and city and county comprehensive land use plans (OAR Chapter 340,
Division 18). Rather than have DEQ staff review local land use regulations to determine whether a DEQ action is compatible
with local land use regulations, DEQ requests the assistance of local governments through the completion of a Land Use
Compatibility Statement (LUCS). If the local government completes the LUCS in the affirmative (checks “yes”), DEQ may
rely on the LUCS to indicate compatibility with local land use requirements and, because state land use goals are implemented
through local land use regulations, DEQ may also use the LUCS to demonstrate that its actions are compatible with state goals.
If a LUCS is checked “no” or contains additional information, further work will need to be done to ensure that DEQ’s action
complies with local land use regulation and state land use goals. For renewals, the permit writer usually only reviews the LUC
if the facility is being remodeled or if increased limits are requested. See OAR 340-018-0050(2)(b) for more detail. The
LUCS form is available on DEQ’s web page: http://www.deq.state.or.us/pubs/permithandbook/lucs.htm
10
This date is to be entered by the permit coordinator, and it is 20 days from the date the permit is signed and mailed (the
issuance date). This is consistent with the definition of the permit effective date in OAR 340-045-0035.
Some NPDES permits issued by DEQ refer to both “waters of the state” and “public waters”. Though OAR Division 45
(“Regulations Pertaining to NPDES and WPCF Permits”) uses these terms interchangeably, the permit template uses the term
“waters of the state” exclusively to reduce the potential for confusion.

The average dry weather design flow (ADWDF) should be included in the permit. In addition to being used to develop mass
load limits for most permits, it is used to determine monitoring requirements and permit fees.
16
See OAR 340-041-0061(9) for rules on how mass load limits are calculated. A graphical representation of OAR 340-0410061(9)(a) through (e) may be found at: http://deq05/wq/wqpermits/docs/MassLoadLimitDecisionTree.pdf
As described in the OAR and explained in the graph, mass load limits may be based on average dry weather flow, average wet
weather flow, a TMDL waste load allocation, or they may be established by the EQC. The date that a wastewater treatment
plant was built (before or after June 30, 1992) can also determine how mass load limits are calculated.
17
This language must be included in the permit as per OAR 340-041-0061(3)(c).
18
The 2004 Bacteria position paper uses the term log mean and geometric mean interchangeably, while the Bacteria Rule
(OAR 340-041-009) simply uses the term log mean. This is unfortunate because log mean can be confused with logarithmic
average which is something different (see Wikipedia at http://en.wikipedia.org/wiki/Geometric_mean#Log-average). The
permit template includes both log mean and geometric average to avoid the confusion that could result from using the term log
mean by itself.
19
This is equivalent to 1% of a 31 day month.
20
Former versions of the permit template asked the permittee to report the amount of chlorine used. This information is not as
useful as total residual chlorine and so the requirement is no longer included.
21
DEQ Quality Assurance Officer Scott Hoatson with the DEQ Lab says that according to Standard Methods procedures, the
lowest detectable concentration under ideal conditions is between 0.010 mg/L and 0.020 mg/L. Wastewater however does not
represent ideal conditions. Scott therefore suggests no less than 0.050 mg/L for wastewater. He also suggests that for some
industrial wastes we may need to go to 0.10 mg/L (e.g. fish processing).
22
See federal regulations. 40 CFR § 122.45(f).
23
This note applies to STEP systems only. It was developed by Western Region permitting staff using Best Professional
Judgment. The reason DEQ has decided to assume that influent BOD and TSS concentrations are 200 mg/L is that the
municipalities that have such systems are typically very small, and have limited ability to establish performance-based limits.
24
Permittees may have additional time if they have a hardship exemption. The basis for the hardship is based on the particulars
of the permittee’s situation. The permittee should negotiate the shortest practicable time with the permittee and specify it in the
permit. In no case should the time exceed 72 hours.
25
Past versions of the permit template have included the following language: All effluent limitations must be met at the end of
the outfall pipe. No wastes may be discharged or activities conducted that cause or contribute to a violation of water quality
standards in OAR 340-041 applicable to the XXX basin except as provided for in OAR 340-045-0080. DEQ has elected to
remove the first sentence because it is redundant. DEQ has elected to delete the second sentence because it may create
confusion on the applicability of the permit shield rule in OAR 340-045-0080(1).

29
This is required to comply with OAR 340-055-0020.
See ORS 215.246(a). The complete reference is as follows:
215.246 Approval of land application of certain substances; subsequent use of tract of land; consideration of
alternatives. (1) The uses allowed under ORS 215.213 (1)(y) and 215.283 (1)(v):
(a) Require a determination by the Department of Environmental Quality, in conjunction with the department’s
review of a license, permit or approval, that the application rates and site management practices for the land application of reclaimed water, agricultural or industrial process water or biosolids ensure continued agricultural, horticultural or silvicultural production and do not reduce the productivity of the tract.
30
These are good management practices to prevent water quality impacts and nuisance conditions as well as meet the
requirements of ORS 215.246(1)(a) that requires DEQ to determine that the application rates and site management practices
"ensure continued agricultural, horticultural or silvicultural production and do not reduce the productivity of the tract."
The rules don’t specify what “oxidized” means. The term is not intended to prescribe a form of treatment, instead it is
intended to ensure recycled water is treated to the point that it is not putrid.

The permittee is required to filter the water even if they can meet the NTU levels without filtration.
33
All new facility designs should be consistent with OAR 340-055-0012(7)(c)(A) to place filtration before disinfection. Since
the reverse design is a poor engineering practice, legacy facilities are expected resolve the design problem during future plant
upgrades.

to the primary PR and VAR methods may be used when identified in the approved BSMP. The BSMP should require that
DEQ be notified when alternate methods are used. Additional methods may be added to the BSMP during the term of the
permit without public notice, because changes to PR and VAR measures are not part of the land application plan. For more

DEQ recognizes that high TSS levels in influent can make achievement of QLs difficult, and at this time DEQ is not
requiring that influent monitoring be performed using the QLs listed in the permit.

Permit writer should consult with permittee regarding the best description to use. It is important that the location description
not restrict permittee from changing treatment technology or upgrading facilities for the duration of the permit, while at the

a. DEQ must approve the use of stream monitoring data collected by another entity (for example, USGS) prior to being
used; and
b. DEQ acknowledges that uninterrupted data collection is not guaranteed. In the event of equipment failure or less, the
permittee must notify DEQ and deploy repaired or new equipment to minimize interruption of data collection. During
any period of data loss beyond the reasonable control of the permittee, temperature and/or pH may be estimated by
any method acceptable to DEQ.
Note B5: Receiving stream flow rate may be derived from the USGS gauging stations 4339000 Rogue River at Dodge
Bridge, near Eagle Point, and USGS gage 14348000 Little Butte Creek Below Eagle Point, Oregon. In the event that this
data is temporarily unavailable, the permittee may use the historical average adjusted by the relative flows from the nearest
available USGS gauging station. In the event the data from either gauging station becomes permanently unavailable, the
permittee must obtain DEQ approval for an alternative flow determination strategy.

Monitoring for UV dose is preferable to monitoring for UV intensity.
64
This note applies to STEP systems only. It was developed by Western Region permitting staff using Best Professional
Judgment.
65
Permit writer should consult with permittee regarding the best description to use. It is important that the location description
not restrict permittee from changing treatment technology or upgrading facilities for the duration of the permit, while at the
same time it should be sufficiently specific that samples are collected in a consistent fashion.
66
Previous versions of the template have stated that the QL for mercury may need to be modified for permittees located in the
Willamette, Monitoring results by various municipalities indicate that a QL of 0.005 ug/L is sufficient to detect the presence of
mercury. There is no rule language regarding QLs, and TSD states that the setting of QLs is a state prerogative.
Oregon’s water quality criterion is for nitrates however the permit requires monitoring for nitrate-nitrate. This is because of
the difference in holding times for the two tests: 48 hours for nitrates as opposed to 28 days for nitrate-nitrate. The holding
time of only 48 hours for nitrates poses logistical challenges. Furthermore, nitrite is almost always not detected or is detected
at very low concentrations, so running nitrate-nitrite as N gives pretty much the same result.

In the event that it IS necessary to test for free cyanide, note that there are multiple approved methods for doing so, and that
the permittee may prefer one over another. For more information, refer to DEQ’s analytical memo on the subject of cyanide
monitoring at http://www.deq.state.or.us/wq/standards/docs/toxics/cyanide.pdf
69
Taking one sample over a 24 hour period would likely result in the loss of VOCs before the sample is analyzed. To reduce
this likelihood, the permit therefore requires the collection of 6 separate samples.

DEQ does not require that WET tests be conducted at the same time as other required monitoring; however it should be
emphasized to the permittee that apart from the upfront cost, there are advantages to doing so. These include potentially
reduced costs of followup investigations if the WET test results indicate toxicity.
72
The type of sample (grab or composite) is dependent on the type of facility, discharge and pollutants of concern. Grab
samples are appropriate for smaller facilities that may not have a composite sampler. Grab samples are also appropriate for
intermittent discharges and for discharges where the pollutants of concern include volatiles.

Other monitoring parameters may be added as necessary for a particular facility. This should be determined based on the
screening information provided with the permit application, sources of wastewater collected, and the end use (as necessary to
protect public health, the environment, and continued agricultural productivity of soils).

See OAR 340-050-0035(2)(a). Note that though some older permits require monitoring for Ag and Cr, the OAR does not
require this. It does however require monitoring for Mo.
The language from the EPA permit application form is as follows: “Applicants that discharge to waters of the US must
provide effluent testing data for the following parameters. Provide the indicated effluent testing for each outfall through which
effluent is discharged. All information reported must be based on data collected through analysis conducted using 40 CFR Part
136 methods. In addition, this data must comply with QA/QC requirements of 40 CFR Part 136 and other appropriate QA/QC
requirements for standard methods for analytes not addressed by 40 CFR Part 136. At a minimum, effluent testing data must be
based on at least three pollutant scans and must be no more than four and one-half years old.”
80
81
Language stating that reports must be in a DEQ-approved format is intended to allow DEQ to specify a format after the
permit has been issued without having to modify the permit.

Though DEQ has not been requiring electronic versions in the past and DOJ says we can start requiring electronic reporting
(with a significant grace period) even if the permit does not specify that reports be submitted electronically.

Wastewater solids differ from biosolids in that they have not yet undergone treatment.
86
Wastewater solids report provides metrics on use/disposal for facilities and data for compliance/technical assistance. A
reporting form will be developed with the biosolids annual report.

A Class I sludge management facility is any publicly-owned treatment works (POTW) required to have an approved
pretreatment program. The CFR language is as follows: 40CFR§503.9(c) Class I sludge management facility is any publicly
owned treatment works (POTW), as defined in 40 CFR 501.2, required to have an approved pretreatment program under 40
CFR 403.8(a) (including any POTW located in a State that has elected to assume local program responsibilities pursuant to 40
CFR 403.10(e)) and any treatment works treating domestic sewage, as defined in 40 CFR 122.2, classified as a Class I sludge
management facility by the EPA Regional Administrator, or, in the case of approved State programs, the Regional
Administrator in conjunction with the State Director, because of the potential for its sewage sludge use or disposal practice to
affect public health and the environment adversely.
90
This date is not in rule and is negotiable.

Though the OAR does not specifically require that all facilities have an I/I program or that they submit an annual report,
including such requirements in the permit will help municipalities maintain the investment of public funds that their collection
system represents. These requirements may be waived in the case of small commercial facilities that don’t really have
collection systems or that have no evidence of I/I.

OAR 340-050 requires a land application plan regardless of the Class of biosolids. However, since the land application of
Class A biosolids are not subject to the same conditions as Class B biosolids, the land application plan may not require the
same level of detail. In any case, Class A facilities may want to maintain a land application plan that allows them the option of
land applying Class B biosolids. See the Biosolids IMD for more information.

It is preferred that the West Coast species are tested if possible, but there may be some difficulty in getting some of the
organisms especially the west coast mysids. As always test organisms should be chosen based on potential toxicants & areas of
concern, ie. If the discharge is into a shellfishing area, it is recommended that a mussel or oyster test be conducted for the
invertebrate instead of the mysids. For more information, contact DEQ WET test specialist Lori Pillsbury.
