SCHEDULE A: WASTE DISCHARGE LIMITS

[1.] Outfall 001 – Permit LimitsTreated effluent from outfall 001 must meet the following limits:

a. BOD5 or CBOD5 and TSS

i. [Adjust summertime dates as needed] May 1 – October 31. [Choose one of the following] During this time period the permittee may not discharge to waters of the state. [or] During this time period the permittee must comply with the limits in the following table:

ii. [Adjust wintertime dates as needed] November 1 – April 30: During this time period the permittee must comply with the limits in the following table:

Table A2: BOD5 or CBOD5 and TSS Limits

ParameterAverage Effluent Concentrations,

mg/LMonthlyAveragelbs/day

WeeklyAveragelbs/day

DailyMaximum

LbsMonthly WeeklyBOD5 or CBOD5 upon requestTSS

iii. 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 permit holder-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 340-041-0061(a).

(C)[(D)] 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.

b. Additional Parameters.

Permittee must comply with the limits inof the following table (year- around except as noted):

Table A3: Limits for Additional Parameters

Year-round(except as noted)

Limits (bacteria limits assume no bacteria TMDL in place)

BOD5 or CBOD5 and TSS Removal Efficiency

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 permit holderpermittees who have elected to build storage capacity to reduce temperature impact)

Daily Maximum

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.pH If compliance is to be established with respect to grab samples:

May not be outside the range of XX to XX S.U.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.

Chlorine, Total Residual20 The monthly average effluent concentration limit is XX mug/L. The daily maximum effluent concentration limit is XX mug/L.

Include if applicable:DEQ has established a minimum Quantitation Limit of 0.05 mg/L215.0 ug/l 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 bioaccumuat-ivebioaccumulative. 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

c.





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. 25

2. Regulatory Mixing Zone

[Include if there is no mixing zone] There is no regulatory mixing zone for this discharge26.

[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.] Outfall Inspection

During the year XXXX (3rd year of permit issuance), the permittee must inspect outfall 001 and submit a written report to DEQ within the same year regarding the integrity of the outfall. The report should include a description of the outfall as originally constructed, the condition of the current outfall and a discussion of any repairs that would need to be performed to return the outfall to its originally designed condition.

[4.] 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 disposed of in a manner that will prevent a violation of the Groundwater Quality Protection Rules (OAR Chapter 340, Division 40).

3.[5.] 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 A427.

b. Managed in accordance with its DEQ-approved Recycled Water Use Plan28 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 quality29.

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 site30.

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 pollutants31.

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 permit holderpermittee decides to change their level of treatment.

If facility uses UV disinfection, include the following:5.[7.] Chlorine Usage

No chlorine or chlorine compounds may be used for disinfection purposes and no chlorine residual resulting from chlorine used for maintenance purposes may be allowed in the effluent. [The purpose of this condition is to avoid having to require the permit holderpermittee to monitor for chlorine to prove they are not using it. If the permit holderpermittee wishes to use either chlorine or UV, the permit must include a permit limit for chlorine as well as a monitoring requirement.]



Include the following for municipalities required to submit these plans. To make this determination, refer to the IMD on Implementation of the Methylmercury Criterion at: http://www.deq.state.or.us/wq/pubs/imds/IMD-methylmercuryCriterion.pdf.6.[8.] 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 permit holderpermittee 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:

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.

f. Ongoing monitoring of effluent to enable evaluation of the effectiveness and implementation of the MMP.

Before approving the plan, The Department DEQ will put the plan out on public notice for 30 days. prior to DEQ’s approval. The permit holderpermittee must begin implementation of the plan within one month of DEQ’s approval. If DEQit is determineds 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.

There are 2 versions of Schedule B. Use this version for facilities that DO NOT monitor for toxics other than chlorine and ammonia (this currently includes most minor domestic facilities).

SCHEDULE B: MINIMUM MONITORING AND REPORTING REQUIREMENTS

1. Monitoring and Reporting Protocols

a. 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, 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 the DEQ permit writer or inspector.

b. Reporting Procedures

i. Significant Figures

Mass load limits all have two significant figures unless otherwise noted51.

ii. Calculating 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. Influent Monitoring and Reporting Requirements

The permittee must monitor influent specify location such as “between the bar screen and the aerated grit chamber” 52 and report results as listed below.

6.[7.] Biosolids Monitoring Requirements

The permittee must monitor biosolids land applied or produced for sale or distribution as listed in the tables below. The samples must be representative of the quality and quantity of biosolids generated and must have undergone the same treatment process used to prepare the biosolids70.



I incorporated this after seeing it in a permit by Jayne West. Ron Doughten said it was a good idea.


Table B7: Biosolids Monitoring

Note: the language in the following table has been written so that it requires no modification by the permit writer. It also captures the situation where a facility’s monitoring may change on a yearly basis, depending on the quantity of biosolids produced, and insures that a facility isn’t required to monitor more or less frequently than required by rule or federal regulation.

7.[8.] Permit Application Monitoring Requirements

The renewal application for this permit requires 3 scans [permit writer may choose to increase to 4] 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.

Table B9: Effluent Monitoring Required for NPDES Permit Application (a minimum of 3? scans required)

Permit writer may choose to increase to 4. Parameters that are already monitored on a regular basis under Table B2 should be deleted from table.

There are 2 versions of Schedule B. Use this version for facilities that monitor for Table 40 toxics. Such facilities include all major domestic facilities, some minor domestic facilities and all industrial facilities. Note that not all facilities need to monitor all pollutants listed in this Schedule. This is especially true for parameters found in the tables entitled “Pesticides and PCBs” and “Other parameters with state water quality criteria”. Refer to the RPA IMD for details.

SCHEDULE B: MINIMUM MONITORING AND REPORTING REQUIREMENTS

1. Monitoring and Reporting Protocols

a. Test Methods

i. Test Methods – monitoring must be conducted according to test procedures in 40 CFR Part 136 and 40 CFR 503 for biosolids or other approved procedures as per Schedule F.

b. 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)83 – 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.

c. 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.



(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 QLs84, 85 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.

d. 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 the DEQ permit inspector.

e. 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, fecal coliformbacteriological analytes, and nitrate-nitrite, total phenols and pH. For temperature and pH, neither the QL nor the DL need to be reported. For these other parameters, the permittee is only required to report the QL and only when the result is ND.

i.[ii.] The permittee must report the same number of significant digits as the permit limit for a given parameter86.

ii.[iii.] CAS Numbers. CAS numbers (where available) must be reported along with monitoring results.

iii.[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.

iv.[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 requirement 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

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].

2. Influent Monitoring and Reporting Requirements

The permittee must monitor influent specify location, such as between the bar screen and the aerated grit chamber87 and report results in accordance with the table below.

Table B1: Influent Monitoring

(Refer to the Monitoring and Reporting Matrices on the Permit Writers’ Corner for monitoring and reporting requirements.)

This is being deleted because there are not criteria for total phenolic compounds, instead there are criteria and monitoring requirements for individual phenolic compounds.


In order to simplify permit development/issuance and the RPA process, the senior permit group has decided to eliminate monitoring for surrogates. The cost savings associated with monitoring for surrogates are negligible.


Pollutanta a CASb QL Pollutanta CASb QLNotes:The permittee must analyze all metals for total concentration. In the case of cadmium, lead, nickel, silver and zinc, if total concentrations exceed the criteria at the “end of pipe”, the permittee must re-monitor and analyze for the dissolved concentration. This is due to the fact that water quality criteria for these metals are based on dissolved concentrations, not total. Chemical Abstract ServiceIf the result for Total Arsenic exceeds 1.0 µg/L, it will be necessary for the permittee to monitor for Arsenic, Total Inorganic Arsenic and Total Inorganic Dissolved Arsenic as part of Tier 2 monitoring. The permittee must use Method 1632A to monitor for the Inorganic Arsenic parameters..

a. The term “total” used in reference to metals is intended to cover all EPA-accepted standard digestion methods and is considered to be equivalent to the term “total recoverable”.

b. Chemical Abstract Servicec. There are multiple approved methods for testing for free cyanide. 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

d. If the result for Total Chromium exceeds 10 µg/L, it will be necessary for the permittee to monitor for Chromium III and Chromium VI as part of Tier 2 monitoring.

[a.] When sampling for Total Cyanide, the permittee must collect at least six discrete grab samples over the operating day with samples collected no less than one hour apart. The aliquot must be at least 100 mL and collected and composited into a larger container that has been preserved with sodium hydroxide to insure sample integrity. If the result for Total Cyanide does not exceed 5.0 µg/L, it is not necessary for the permittee to test for free cyanide. 101

6. Ambient and Additional Effluent Characterization Monitoring (Tier 2 Monitoring)

DEQ will evaluate the results of monitoring required under Schedule B condition 5?: Effluent Toxics Characterization Monitoring (also referred to as Tier 1 monitoring) to determine whether the permittee will be required to conduct additional ambient water quality and/or effluent monitoring (also referred to as Tier 2 monitoring). DEQ will notify the permittee of its determination through a written “Monitoring Action



Letter.” (For help in drafting this letter, see sample on permit development page of sharepoint under the Monitoring and Reporting heading.)

[a.] Sampling Plan

If additional monitoring is needed, the permittee must submit a sampling plan to DEQ for approval within 3 months of receipt of the DEQ Monitoring Action Letter. The sampling plan must include the following:

[i.] Characterization of ambient water quality for any pollutants identified as having the reasonable potential to exceed the water quality criterion at the point of discharge.

[ii.] Additional effluent monitoring for any pollutant for which the concentration of a surrogate is found to exceed the water quality criterion or criteria at the point of discharge. [Surrogate parameters to which this language may apply are as follows:

Total Arsenic for Inorganic Arsenic and Arsenic III Total Chromium for Chromium III and Chromium VI Total Cyanide for Free Cyanide Total Cadmium, Lead, Nickel, Silver and Zinc in lieu of Dissolved Cadmium,

Lead, Nickel, Silver and Zinc respectively. If this condition is included in the permit, Tables B4 and B9 should be modified to require monitoring for the surrogates.]

[iii.] Additional effluent monitoring (six additional samples each) for any pollutants identified by Tier 1 characterization monitoring results as having reasonable potential to exceed the water quality criteria at the point of discharge.

[iv.] Completion of Schedule B sampling requirements that could not be completed due to analytical interferences.

[v.] Characterization of effluent and ambient water quality for new pollutant parameter(s) adopted by the EQC after permit issuance104.

[vi.] Characterization of effluent and ambient water quality, if necessary, when the receiving stream is listed as impaired on the DEQ 303(d) list for new parameter(s).105

[vii.] Sampling locations for receiving water must be located as far upstream from outfall location as necessary to insure that samples contain no effluent.

[viii.] [For permits where information on flow and ambient water quality may not be available] Monitoring of ambient conditions. The sampling plan must include monitoring for flow, temperature, ph, hardness and alkalinity.

[ix.] [For permits with mixing zones]Timing of sampling must coincide with the critical period which is [insert time of year].

[b.] Implementation

The permittee must implement the approved plan within X months of approval and report the ambient and additional characterization by 36 months after permit issuance.



All of this language is being deleted from the permit because it more properly belongs in the monitoring action letter.


7. Whole Effluent Toxicity (WET) Testing Requirements

The permittee must monitor final effluent for whole effluent toxicity as described in Table B10? using the testing protocols specified in Schedule D, condition 12?, Whole Effluent Toxicity Testing for Saltwater or Freshwater (pick one) for Outfall 001 must be collected at the location specified below.

Table B10: WET Test Monitoring

Parameter Minimum Frequency Sample Type/Location ReportAcute toxicity

The permit holderpermittee must monitor 4 times over the permit cycle with each sample collected during a different quarter (modify as needed for seasonal discharges). All four samples may be collected in the first year of the permit or they may be collected during a different quarter each year over 4 years (i.e., Year 1, Qtr 1) (This language may be modified so that WET testing coincides with effluent toxics characterization monitoring) When possible, conduct WET testing concurrent with Effluent Toxics Characterization Monitoring as described in Schedule D, Condition 12?106.

If a particular test shows toxicity at include if there is a ZID: the acute (ZID) or the chronic (RMZ) dilutions, the permittee must re-test and if necessary evaluate the cause of toxicity as described in Schedule D, Condition 12?.

For acute toxicity: Grab or Composite107, taken specify location, such as: after dechlorination and before the effluent flume108. Location should be the same as monitoring for parameters that may contribute to toxicity.

Report must include test results and backup information such as bench sheets sufficient to demonstrate compliance with permit requirements.

Report must include a statement certifying that the results do or do not show toxicity at dilutions corresponding to the edge of the [modify as needed: ZID and the mixing zone]. The corresponding dilutions are as follows:ZID: XX Mixing zone: XX

A template for providing WET test results is provided below.

Chronic toxicity

For chronic toxicity: 24-hr composite, specify location, such as: taken after dechlorination and before the effluent flume109. Location should be the same as monitoring for parameters that may contribute to toxicity.

The permittee must submit the results of WET tests using the template below, along with laboratory reports.

The following should be included in permits for municipal facilities that discharge more than 0.1 MGD. 9.[10.] Permit Application Monitoring Requirements115

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.

[iv.] Unless approved by DEQ in writing, acute tests must be conducted on a control (0%) and the following dilution series: 6.25%, 12.5%, 25%, 50%, and 100% effluent. [If the permit does not specify a ZID, this dilution series is sufficient. If the permit does specify a ZID, the dilution series should include the effluent percentage (equal to 100/dilution) that is expected at the edge of the ZID, as well as the effluent percentages above and below this value. For example, if the expected dilution is 2.5, the effluent percentage at the ZID is 40%, and an appropriate dilution series would be 50%, 40%, 20%, 10% effluent and lab control. For additional help in defining the dilution series refer to http://deq05/wq/wqper-mits/Guidance/WETPermitLanguageInstructions.pdf on the Permit Writers’ Corner.]

[Insert the % effluent at the edge of the RMZ here, if no RMZ remove the language about the mixing zone and insert 100%]





c.[d.] Dual End-Point Tests

i. WET tests may be dual end-point tests in which both acute and chronic end-points can be determined from the results of a single chronic test. The acute end-point must be based on 48-hours for the Holmesimysis costata (mysid shrimp) or A. bahia and 96-hours for the Menidia beryllina (inland silverside).

ii. All test methods and procedures must be in accordance with Short-Term Methods for Estimating the Chronic Toxicity of Effluents and Receiving Waters to Marine and Estuarine Organisms, Third Edition, EPA-821-R-02-014, October 2002.

d.[e.] Sampling Requirements

At the time of WET sampling, the permittee must collect and analyze effluent samples must also be collected and analyzed for XX, XX [Insert parameters from Schedule B that may be of concern in the effluent for toxicity. Note: this language is not meant to be an additional requirement. Instead, the purpose is to insure that sampling for parameters already required in Schedule B hat may contribute to the toxicity of the effluent, occurs at the same time that samples for WET tests are collected. The intent is to facilitate the use of this data in the interpretation of WET tests.]

e.[f.] Evaluation of Causes and Exceedances

i. If any test exhibits toxicity as defined, the permittee must conduct another toxicity test using the same species and DEQ-approved methodology within two weeks unless approved by DEQ.

ii. If two consecutive WET test results indicate acute or chronic toxicity, the permittee must immediately notify DEQ of the results. DEQ will work with the permittee to determine the appropriate course of action to evaluate and address the toxicity. [The IMD offers a variety of actions that can be undertaken to evaluate toxicity. The permit writer, WET coordinator, and facility should work together to define the action.]

f.[g.] Quality Assurance / Reporting

i. Quality assurance criteria, statistical analyses, and data reporting for the WET tests must be in accordance with the EPA documents stated in this condition.

[ii.] All test methods and procedures must be in accordance with Short-Term Methods for Estimating the Chronic Toxicity of Effluents and Receiving Waters to Freshwater Organisms, Fourth Edition, EPA-821-R-02-013, October 2002. If the permittee wants to deviate from the bioassay procedures outlined in this method, the permittee must submit a written request to DEQ for review and approval prior to use. Any deviation of the bioassay procedures outlined in this method must be submitted in writing to DEQ for review and approval prior to use.

[iii.] Unless otherwise approved by DEQ in writing, tests run as dual end-point tests must be conducted on a control (0%) and the following dilution series: 6.25%, 12.5%, 25%, 50%, and 100% effluent.

If the permit does specify a ZID and an RMZ, the dilution series should include the effluent percentages (equal to 100/dilution) that correspond to those expected at the edge of each. For example, if the expected dilution is 2.5 at the ZID is 2.5 and 20 at the RMZ, the effluent percentages at the ZID and RMZ are 40% and 5% respectively, the effluent percentage is 40% at the ZID and 5% at the RMZ, and an appropriate dilution series would be100%, 70%, 40%, 5%, 2.5% and 0% effluent. For additional help in defining the dilution series, refer to http://deq05/wq/wqpermits/Guidance/WETPermitLan-guageInstructions.pdf on the Permit Writers’ Corner.]

ii.[iv.] Toxicity determinations for dual end-point tests must correspond to the acute and chronic tests described in conditions 9.b.v? and 9.c.v? above.

d.[e.] Sampling Requirements

At the time of WET sampling, the permittee must collect and analyze effluent samples for XX, XX [Insert parameters from Schedule B that may be of concern in the effluent for toxicity. Note: this language is not meant to be an additional requirement. Instead, the purpose is to insure that sampling for parameters already required in Schedule B hat may contribute to the toxicity of the effluent, occurs at the same time that samples for WET tests are collected. The intent is to facilitate the use of this data in the interpretation of WET tests.]

e. Evaluation of Causes and Exceedances

i. If any test exhibits toxicity as described in conditions 13.b.v.? and 13.c.v.? above, the permittee must conduct another toxicity test using the same species and DEQ-approved methodology within two weeks unless otherwise approved by DEQ.

ii. If two consecutive WET test results indicate acute or chronic toxicity as described in conditions 13.b.v.? and 13.c.v.? above, the permittee must immediately notify DEQ of the results. DEQ will work with the permittee to determine the appropriate course of action to evaluate and address the toxicity. [The IMD offers a variety of actions that can be undertaken to evaluate toxicity. The permit writer, WET coordinator, and facility should work together to define the action.]





f. Quality Assurance and Reporting

i. Quality assurance criteria, statistical analyses, and data reporting for the WET tests must be in accordance with the EPA documents stated in this condition.

[ii.] For each test, the permittee must provide aA bioassay laboratory report for each test must be prepared according to the EPA method documents referenced in this Schedule. The report must include all QA/QC documentation, statistical analysis for each test performed, standard reference toxicant test (SRT) conducted on each species required for the toxicity tests, and completed Chain of Custody forms for the samples including time of sample collection and receipt. The permittee must submit rReports must be submitted to DEQ within 60 days of test completion.

ii.[iii.] The report must include all endpoints measured in the test: NOEC (No Observed Effects Concentration), LOEC (Lowest Observed Effects Concentration), and IC25 (chronic effect 25% inhibition concentration).

iii.[iv.] The permittee must make available to DEQ upon request the written standard operating procedures they, or the laboratory performing the WET tests, use for all toxicity tests required by DEQ.

g. Reopener

DEQ may reopen and modify this permit to include new limits, monitoring requirements, and/or conditions as determined by DEQ to be appropriate, and in accordance with procedures outlined in OAR Chapter 340, Division 45 if:

i. WET testing data indicate acute and/or chronic toxicity.

ii. The facility undergoes any process changes.

iii. Discharge monitoring data indicate a change in the reasonable potential to cause or contribute to an exceedance of a water quality standard.

END OF FRESHWATER LANGUAGE FOR WET TESTING

The permittee must have its system supervised on a part-time or full-time basis by one or more operators who hold a valid certificate for the type of wastewater treatment or wastewater collection system the operator is supervising and at a grade equal to or greater than the wastewater system’s classification145 specified on page one of this permit.

Include the following for all wastewater systems: e. The permittee's wastewater system may not be without the designated supervisor for more than 30

days. During this period, there must be another person available to supervise who is certified at no more than one grade lower than the classification of the wastewater system. The permittee must delegate authority to this operator to supervise the operation of the system.146

[f.] If the wastewater system has more than one daily shift, the permittee must have another properly certified operator available to supervise operation of the system. Each shift supervisor, if any, must be certified at no more than one grade lower than the system classification.147

f.[g.] The permittee is not required to have a supervisor on site at all times; however, the supervisor must be available to the permittee and operator at all times.148

[h.] The permittee must notify DEQ in writing of the name of the system supervisor. The permittee may replace or re-designate the system supervisor with another properly certified operator at any time and must notify DEQ in writing within 30 days of replacement or re-designation of operator in charge.149 As of this writing, the notice of replacement or re-designation must be sent to Water Quality Division, Operator Certification Program, 700 NE Multnomah St, Suite 600, Portland, OR 97232-41002020 SW 4th Avenue, Suite 400, Portland, OR 97201. This address may be updated in writing by DEQ during the term of this permit.

g.[i.] When compliance with item (e) of this section is not possible or practicable because the system supervisor is not available or the position is vacated unexpectedly, and another certified operator is not qualified to assume supervisory responsibility, the Director may grant a time extension for compliance with the requirements in response to a written request from the system owner. The Director will not grant an extension longer than 120 days unless the system owner documents the existence of extraordinary circumstances.

c.[d.] A description of the applicable reporting requirements. These must be consistent with the reporting requirements found in Schedule F, condition D.5.

This must be included in all POTW permits that don’t already have a pretreatment program: 16. 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 issuance 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 waters. 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 datere-issuance.

Guidance on conducting IU Surveys can be found at http://www.deq.state.or.us/wq/pretreatment/docs/guid-ance/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 permit renewalthe 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 pre-treatment 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 frame150. 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 Pretreat-ment 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 self-monitoring, 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. The results of such activities must be available to DEQ upon request. 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:



a. Description of discharge practices, including non-routine batch discharges;

b. Description of stored chemicals;

c. 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.

9. 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) 151. 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 POTW152.

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



substantial program modifications may be implemented by the delegated program prior to receiving written authorization from DEQ.



SCHEDULE F: NPDES GENERAL CONDITIONS

For this Schedule to appear in the Table of Contents, do not delete the above. Insert the appropriate version of the General conditions. These may be found at:

General Conditions - all versions

This link is from the Permit Development sharepoint page.


1 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.3 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.s-tate.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. 4 If no street address is available, lat/long should be provided.

5USGS 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 3rd 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.htm10

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. 11

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.

12 See OAR 340-045-0080 entitled “Effect of a Permit”.

13 See OAR 340-045-0015 entitled “Permit Required”.

14 See OAR 340-0045-0080 entitled “Effect of a Permit”. 15

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 340-041-0061(9)(a) through (e) may be found at: http://deq05/wq/wqpermits/docs/MassLoadLimitDecisionTree.pdfAs 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 permit holderpermittee 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 Permit holderPermittees may have additional time if they have a hardship exemption. The basis for the hardship is based on the particulars of the permit holderpermittee’s situation. The permit holderpermittee should negotiate the shortest practicable time with the permittee and specify it in the permit. In no case should the time exceed 72 hours.

26 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). 27

See OAR 340-055-0012(2) which is as follows: Any person who uses recycled water may use recycled water only for the beneficial purposes described in this rule, and must comply with the standards and requirements of this rule and the rules of this division.28 See OAR-055-016(2).

29 This is required to comply with OAR 340-055-0020.30 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; considera-tion 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.

31 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."

32 The rules don’t specify what “oxidized” means. The term is not intended to prescribe a form of treatment, instead it

http://en.wikipedia.org/wiki/Geometric_mean#Log-average

http://en.wikipedia.org/wiki/Geometric_mean#Log-average

is intended to ensure recycled water is treated to the point that it is not putrid.

33 The permit holderpermittee is required to filter the water even if they can meet the NTU levels without filtration.

34All 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.

35 In the event that a permit holderpermittee collects multiple samples on a single day, the accepted practice is that the permittee should report the median of all the samples collected on that day. This median value is then one of the required 7 values. See OAR 340-055-0012(7)(c) and (d) for Class A recycled water.

36 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.

37 In the event that a permit holderpermittee collects multiple samples on a single day, the accepted practice is that the permittee should report the median of all the samples collected on that day. This median value is then one of the required 7 values. See OAR 340-055-0012(6)(c) and (d) for Class B recycled water.


39 In the event that a permit holderpermittee collects multiple samples on a single day, the accepted practice is that the permittee should report the median of all the samples collected on that day. This median value is then one of the required 7 values. See OAR 340-055-0012(5)(c) and (d) for Class C recycled water.

40 The rules don’t specify what “oxidized” means. The term is not intended to prescribe a form of treatment. Rather the term is intended to ensure recycled water is treated to the point that it is not putrid.


42 This phrase clarifies that the conditions apply to biosolids that are added to other products.

49 See OAR 340-050-0026. The Biosolids IMD (http://www.deq.state.or.us/wq/pubs/imds/biosolids.pdf) describes pathogen reduction (PR) and vector attraction reduction (VAR) options. DEQ’s Biosolids Specialist may also be contacted. Alternatives 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 information, contact Biosolids Specialist at 503-229-5472.

50 See OAR 340-050-0026(2)(a). The term “ceiling concentration” was chosen instead of say, maximum concentration, in order to be consistent with state and federal regulations. The term “pollutant concentration” was chosen in order to be consistent with state and federal regulation.

52 Permit writer should consult with permit holderpermittee regarding the best description to use. It is important that the location description not restrict permit holderpermittee 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.

53 For continuous monitoring requirements, consider specifying backup monitoring procedure (either grab or backup continuous monitor) in the event of equipment failure.

54 For flow-through facilities, the monitoring location should be either on the influent or the effluent. If the facility has storage (such as lagoon treatment system), require monitoring on both the influent and effluent.

59 The Monitoring Matrix may be found on the Permit Writers’ Corner under the Monitoring heading at: http://deq05/wq/wqpermits/PCGuidance.htm#MR

60 Example: ETL= Qe x (Te-Twq) x C. Check TMDL for formula to use.

61 The Medford permit includes the following language regarding flow monitoring and it is provided as an example for when the permit holderpermittee relies on gages maintained by others for instream flow.

Note B1: The following applies to continuous monitoring when used for the parameters in Schedule B above:a. DEQ must approve the use of stream monitoring data collected by another entity (for example, USGS)

prior to being used; andb. 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.62

Monitoring for UV dose is preferable to monitoring for UV intensity. For more information, refer to Monitoring Matrix on the Permit Writers’ Corner.

63 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.

64 DEQ does not require that WET tests be conducted at the same time as other required monitoring; however it should be emphasized to the permit holderpermittee 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.

65 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.

69 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).

70 See OAR 340-050-0035(2)(c).

71 See OAR 340-050-0035(2)(a).

72 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.

73 Language stating that reports must be in a DEQ-approved format is intended to allow DEQ to specify a format without having to modify the permit.74 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. 75 DEQ’s Biosolids and Water Resuse Coordinator is developing a standard reporting form. Contact at (503) 229-5472 for details.

76 The date and number of recycled water annual reports to be submitted is specified in the Recycled Water IMD section3.4.4, page 42.

77 Wastewater solids differ from biosolids in that they have not yet undergone treatment.

78 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.

79 No date is given in rule. This date was selected to coordinate with the biosolids annual report.

80 The February 19th date is specified in OAR 340-050-0035(6) and 40 CFR §503.18.

81 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.

82 This date is not in rule and is negotiable.

83 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. 84 Elevated TSS levels can result in matrix effects.

85 See page 41 of EPA’s “Solutions to Analytical Chemistry Problems with Clean Water Act Methods”, March 2007 for




why matrix interference needs to be demonstrated, and see page 42 for how to make sure a demonstration. http://water.epa.gov/scitech/methods/cwa/atp/upload/2008_02_06_methods_pumpkin.pdf86 For more information, refer to the Significant Figures IMD at http://www.deq.state.or.us/wq/pubs/imds/Sig-FigsIMD.pdf

99 Previous versions of the template have stated that the QL for mercury may need to be modified for permit holderpermittees 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.

100 Oregon’s water quality criterion is for nitrates however the permit requires monitoring for nitrate-nitrate. This is






http://water.epa.gov/scitech/methods/cwa/atp/upload/2008_02_06_methods_pumpkin.pdf

because of the difference in holding times for the two tests: 48 hours for nitrates as opposed to 28 days for nitrate-ni-trate. 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.

101 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 permit holderpermittee 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

102 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.

103 For more background, refer to DEQ’s analytical memo on the subject of 1,2 Diphenylhydrazine at http://www.de-q.state.or.us/wq/standards/docs/toxics/diphenylhydrazine.pdf

104 This requirement is intended to insure that new water quality criteria are incorporated into permits in a timely manner. Without this requirement, it may take upwards of two permit cycles for a permit to reflect new water quality criteria. By contrast, with this permit condition, monitoring may occur within the term of the current permit cycle and a permit limit (if needed) can be developed when the permit is renewed.

105 This requirement is intended to insure that when the receiving stream is found to be water quality-limited (is placed on the 303(d) list) for a new parameter, permit limits that reflect the listing are incorporated into the permit in a timely a manner. Without this requirement, it may take upwards of two permit cycles for the permit to reflect the 303(d) listing. By contrast, with this permit condition, monitoring may occur within the term of the current permit cycle and a permit limit (if needed) can be developed when the permit is renewed.

106 DEQ does not require that WET tests be conducted at the same time as other required monitoring; however it should be emphasized to the permit holderpermittee 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.

107 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.

114 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.

115 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

http://www.deq.state.or.us/wq/standards/docs/toxics/diphenylhydrazine.pdf


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.”

116 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. 117 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.118 Ron Doughten is developing a standard reporting form. Contact him for details.

127 This language must be included in the permit as per the Compliance Schedule IMD. This IMD may be found at: http://www.deq.state.or.us/wq/pubs/imds/ComplianceSchedule.pdf

128 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.

134 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.

138 OAR 340-050-0031(1) requires only 60 days, however, this time frame is generally too short to meet.

139 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.

140 See OAR 340-049-0010(17).
