Please amend DMRs accordingly: • Monthly TN loading should be reported 12 times a year. Reporting of Monthly TN Loading for February, March and April is missing. • Data was reported as zero (0) for Ammonia, BOD, Fecal Coliform, and TSS. Reporting zero for any parameter, with few exceptions such as temperature, is inadequate reporting. The method PQL should be reported along with the data modifier "less than" (<) instead of zero. Minimum detection and reporting levels (MDLs & PQLs) are defined by the DWR Water Sciences Section as follows: Each analytical procedure has a Practical Quantitation Limit (PQL), which is defined as "the lowest concentration that can be reliably achieved within specified limits of precision and accuracy during routine laboratory operating conditions." PQLs are subjectively set at some multiple of typical Method Detection Limits (MDLs) for reagent water (generally 3 to 5 times the MDL). The PQL for a procedure may also be defined by: a reporting limit or minimum limit (ML) specified by the analytical method; sample volume and buret graduations; and/or minimum measurement values that are method - defined. The established PQL for a procedure serves as a reliable and routinely achievable reporting limit for a biological or chemical parameter (hgps://deq.nc. gov/about/divisions/water-resources/water-resources-data/water-sciences- home-page/microbiology inorganics-branch/methods-p-gls-qa). In accordance with NPDES Standard Conditions Part II Section D. 4., the following is required for test procedures: To meet the intent of the monitoring required by this permit, all test procedures must produce minimum detection and reporting levels that are below the permit discharge requirements and all data generated must be reported down to the minimum detection or lower reporting level of the procedure. If no approved methods are determined capable of achieving minimum detection and reporting levels below permit discharge requirements, then the most sensitive (method with the lowest possible detection and reporting level) approved method must be used. • Units of Measure (UoM) — mg/L, vs. µg/L: For Total zinc please carefully report the correct units of measurement in eDMR. When your contract lab report results in mg/L the conversion is to µg/L is to multiply by 1000. When converting from µg/L to mg/L the result is divided by 1000. Please report results for Zinc in µg/L for consistency with permits limits. • For 2016, annual TN loading (parameter code QY600) was reported in February 2016. For 2018 the yearly parameter QY600 for yearly TN was reported 6 times. This parameter QY600 should only be reported once per year in December. The parameter code QM600 should be used for monthly reporting of TN. 4. Instream Data Summary Instream monitoring may be required in certain situations, for example: 1) to verify model predictions when model results for instream DO are within 1 mg/1 of instream standard at full permitted flow; 2) to verify model predictions for outfall diffuser; 3) to provide data for future TMDL; 4) based on other instream concerns. Instream monitoring may be conducted by the Permittee, and there are also Monitoring Coalitions established in several basins that conduct instream sampling for the Permittee (in which case instream monitoring is waived in the permit as long as coalition membership is maintained). Page 4 of 12 DocuSign Envelope ID: 713338A4-3347-4D43-AA05-88EOF55E3FOD If applicable, summarize any instream data and what instream monitoring will be proposed for this permit action: Is this facility a member of a Monitoring Coalition with waived instream monitoring (YIN): Yes. Name of Monitoring Coalition: Lower Neuse River Association. 5. Compliance Summary Summarize the compliance record with permit effluent limits (past 5 years): See attached Monitoring Report Violation BIMS export Oct2015 to Sep2018, 17 pages. The facility received three (3) NODs for BOD and one NOD for Ammonia. For BOD, one (1) was for a monthly average exceedance and two (2) were for weekly average exceedances. For ammonia, the NOD was for a monthly average exceedance. All other violation actions decisions were noted as No Action, best professional judgement (BPJ) or No Action, Facility Reporting Error. Summarize the compliance record with aquatic toxicity test limits and any second species test results (past 5 years): NA. Summarize the results from the most recent compliance inspection: See attached Water Compliance Inspection Report 12/10/18. 6. Water Quality -Based Effluent Limitations (WQBELs) Dilution and Mixing Zones hi accordance with 15A NCAC 2B.0206, the following streamflows are used for dilution considerations for development of WQBELs: 1 Q 10 streamflow (acute Aquatic Life); 7Q 10 streamflow (chronic Aquatic Life; non -carcinogen HH); 30Q2 streamflow (aesthetics); annual average flow (carcinogen, HH). If applicable, describe any other dilution factors considered (e.g., based on CORMIX model results): NA. If applicable, describe any mixing zones established in accordance with 15A NCAC 2B.0204(b): NA. Oxygen -Consuming Waste Limitations Limitations for oxygen -consuming waste (e.g., BOD) are generally based on water quality modeling to ensure protection of the instream dissolved oxygen (DO) water quality standard. Secondary TBEL limits (e.g., BOD= 30 mg/l for Municipals) may be appropriate if deemed more stringent based on dilution and model results. Ifpermit limits are more stringent than TBELs, describe how limits were developed: Limitations for BOD are based on a Streeter Phelps model (Level B) for instream DO protection. No changes are proposed from the previous permit limits. Ammonia and Total Residual Chlorine Limitations Limitations for ammonia are based on protection of aquatic life utilizing an ammonia chronic criterion of 1.0 mg/l (summer) and 1.8 mg/l (winter). Acute ammonia limits are derived from chronic criteria, utilizing a multiplication factor of 3 for Municipals and a multiplication factor of 5 for Non -Municipals. Limitations for Total Residual Chlorine (TRC) are based on the NC water quality standard for protection of aquatic life (17 µg/1) and capped at 28 µg/l (acute impacts). Due to analytical issues, all TRC values reported below 50 µg/l are considered compliant with their permit limit. Page 5 of 12 DocuSign Envelope ID: 713338A4-3347-4D43-AA05-88EOF55E3FOD Describe any proposed changes to ammonia and/or TRC limits for this permit renewal: There are no proposed changes. Reasonable Potential Analysis (RPA) for Toxicants If applicable, conduct RPA analysis and complete information below. The need for toxicant limits is based upon a demonstration of reasonable potential to exceed water quality standards, a statistical evaluation that is conducted during every permit renewal utilizing the most recent effluent data for each outfall. The RPA is conducted in accordance with 40 CFR 122.44 (d) (i). The NC RPA procedure utilizes the following: 1) 95% Confidence Level/95% Probability; 2) assumption of zero background; 3) use of detection limit for "less than" values; and 4) streamflows used for dilution consideration based on 15A NCAC 2B.0206. Effective April 6, 2016, NC began implementation of dissolved metals criteria in the RPA process in accordance with guidance titled NPDES Implementation of Instream Dissolved Metals Standards, dated June 10, 2016. A reasonable potential analysis was conducted on effluent toxicant data collected between May2016 and Sep2018. Pollutants of concern included toxicants with positive detections and associated water quality standards/criteria. Based on this analysis, the following permitting actions are proposed for this permit: • Effluent Limit with Monitoring: The following parameters will receive a water quality -based effluent limit (WQBEL) since they demonstrated a reasonable potential to exceed applicable water quality standards/criteria: Total Zinc. • Monitoring Only: The following parameters will receive a monitor -only requirement since they did not demonstrate reasonable potential to exceed applicable water quality standards/criteria, but the maximum predicted concentration was >50% of the allowable concentration: NA. • No Limit or Monitorin;: The following parameters will not receive a limit or monitoring, since they did not demonstrate reasonable potential to exceed applicable water quality standards/criteria and the maximum predicted concentration was <50% of the allowable concentration: NA. • Summary of new limits added based on RPA: Parameter Monthly Average Limit Daily Maximum Limit Zinc 125.7 µg/L 125.7 µg/L • Summary of existing limits deleted based on RPA: NA. • Other: NA. • POTW Effluent Pollutant Scan Review: Three effluent pollutant scans were evaluated for additional pollutants of concern. o The following parameter(s) will receive a water quality -based effluent limit (WQBEL) with monitoring, since as part of a limited data set, two samples exceeded the allowable discharge concentration: NA. o The following parameter(s) will receive a monitor -only requirement, since as part of a limited data set, one sample exceeded the allowable discharge concentration: NA. If applicable, attach a spreadsheet of the RPA results as well as a copy of the Dissolved Metals Implementation Fact Sheet for freshwater/saltwater to this Fact Sheet. Include a printout of the RPA Dissolved to Total Metal Calculator sheet if this is a Municipality with a Pretreatment Program. Toxicity Testing Limitations Permit limits and monitoring requirements for Whole Effluent Toxicity (WET) have been established in accordance with Division guidance (per WET Memo, 8/2/1999). Per WET guidance, all NPDES permits Page 6 of 12 DocuSign Envelope ID: 713338A4-3347-4D43-AA05-88EOF55E3FOD issued to Major facilities or any facility discharging "complex" wastewater (contains anything other than domestic waste) will contain appropriate WET limits and monitoring requirements, with several exceptions. The State has received prior EPA approval to use an Alternative WET Test Procedure in NPDES permits, using single concentration screening tests, with multiple dilution follow-up upon a test failure. Describe proposed toxicity test requirement: This facility is a minor municipal with a 100%. Toxicity monitoring is not required. No changes are proposed from the previous permit. Mercury Statewide TMDL Evaluation There is a statewide TMDL for mercury approved by EPA in 2012. The TMDL target was to comply with EPA's mercury fish tissue criteria (0.3 mg/kg) for human health protection. The TMDL established a wasteload allocation for point sources of 37 kg/year (81 lb/year), and is applicable to municipals and industrial facilities with known mercury discharges. Given the small contribution of mercury from point sources (-2% of total load), the TMDL emphasizes mercury minimization plans (MMPs) for point source control. Municipal facilities > 2 MGD and discharging quantifiable levels of mercury (>1 ng/1) will receive an MMP requirement. Industrials are evaluated on a case -by -case basis, depending if mercury is a pollutant of concern. Effluent limits may also be added if annual average effluent concentrations exceed the WQBEL value (based on the NC WQS of 12 ng/1) and/or if any individual value exceeds a TBEL value of 47 ng/1 No mercury date is available for the facility. Describe proposed permit actions based on mercury evaluation: To be consistent with 2012 Statewide Mercury TMDL Implementation total Mercury must be monitored once during the permit cycle for a minor municipality. Mercury monitoring is included to provide a database for future mercury management and TMDL evaluation. See Special Condition A. (7). Other TMDL/Nutrient Management Strategy Considerations If applicable, describe any other TMDLs/Nutrient Management Strategies and their implementation within this permit: Total Phosphorus (TP) effluent limits have been changed from Monitor & Report to 2.0 mg/L (weekly average) per the Neuse Permitting Summary Feb 2013. Other WOBEL Considerations If applicable, describe any other parameters of concern evaluated for WQBELs: NA. If applicable, describe any special actions (HQW or ORW) this receiving stream and classification shall comply with in order to protect the designated waterbody: NA. If applicable, describe any compliance schedules proposed for this permit renewal in accordance with 15A NCAC 2H. 010 7(c) (2) (B), 40CFR 122.47, and EPA May 2007 Memo: A 4-year compliance schedule is proposed for meeting the new zinc effluent limit. Annual milestones are included for this Special Condition. If applicable, describe any water quality standards variances proposed in accordance with NCGS 143- 215.3(e) and 1 SA NCAC 2B. 0226 for this permit renewal: NA. 7. Technology -Based Effluent Limitations (TBELs) Municipals if not applicable, delete and skip to Industrials) Page 7 of 12 DocuSign Envelope ID: 713338A4-3347-4D43-AA05-88EOF55E3FOD Are concentration limits in the permit at least as stringent as secondary treatment requirements (30 mg/l BODS/TSS for Monthly Average, and 45 mg/l for BODS/TSS for Weekly Average). YES. If NO, provide a justification for alternative limitations (e.g., waste stabilization pond). NA. Are 85% removal requirements for BODS/TSS included in the permit? YES. If NO, provide a justification (e.g., waste stabilization pond). NA. 8. Antidegradation Review (New/Expanding Discharge): The objective of an antidegradation review is to ensure that a new or increased pollutant loading will not degrade water quality. Permitting actions for new or expanding discharges require an antidegradation review in accordance with 15A NCAC 2B.0201. Each applicant for a new/expanding NPDES permit must document an effort to consider non -discharge alternatives per 15A NCAC 2H.0105( c)(2). In all cases, existing instream water uses and the level of water quality necessary to protect the existing use is maintained and protected. If applicable, describe the results of the antidegradation review, including the Engineering Alternatives Analysis (EAA) and any water quality modeling results: NA. 9. Antibacksliding Review: Sections 402(o)(2) and 303(d)(4) of the CWA and federal regulations at 40 CFR 122.44(1) prohibit backsliding of effluent limitations in NPDES permits. These provisions require effluent limitations in a reissued permit to be as stringent as those in the previous permit, with some exceptions where limitations may be relaxed (e.g., based on new information, increases in production may warrant less stringent TBEL limits, or WQBELs may be less stringent based on updated RPA or dilution). Are any effluent limitations less stringent than previous permit (YES/NO): NO. If YES, confirm that antibacksliding provisions are not violated: NA. 10. Monitoring Requirements Monitoring frequencies for NPDES permitting are established in accordance with the following regulations and guidance: 1) State Regulation for Surface Water Monitoring, 15A NCAC 2B.0500; 2) NPDES Guidance, Monitoring Frequency for Toxic Substances (7/15/2010 Memo); 3) NPDES Guidance, Reduced Monitoring Frequencies for Facilities with Superior Compliance (10/22/2012 Memo); 4) Best Professional Judgement (BPJ). Per US EPA (Interim Guidance, 1996), monitoring requirements are not considered effluent limitations under Section 402(o) of the Clean Water Act, and therefore anti - backsliding prohibitions would not be triggered by reductions in monitoring frequencies. For instream monitoring, refer to Section 4. 11. Electronic Reporting Requirements The US EPA NPDES Electronic Reporting Rule was finalized on December 21, 2015. Effective December 21, 2016, NPDES regulated facilities are required to submit Discharge Monitoring Reports (DMRs) electronically. Effective December 21, 2020, NPDES regulated facilities will be required to submit additional NPDES reports electronically. This permit contains the requirements for electronic reporting, consistent with Federal requirements. 12.Summary of Proposed Permitting Actions: Table.

The facility classification Grade IV Biological Water Pollution Control System has been added to the effluent page. 4. Total Phosphorus (TP) effluent limits have been changed from Monitor & Report to 2.0 mg/L (weekly average) per the Neuse Permitting Summary Feb 2013. 5. Section A. (7.) has been added to reflect current language regarding electronic submission of effluent data. Federal regulations require electronic submittal of all discharge monitoring reports (DMRs). 6. The NC 2007-2014 Water Quality Standard (WQS) Triennial Review was approved by the NC Environmental Management Committee (EMC) on November 13, 2014. The US EPA subsequently approved the WQS revisions on April 6, 2016 with some exceptions. The NC Division of Water Resources is required to implement the new dissolved metal standards in all permits public noticed after April 6, 2016. The new standards for most metals include acute standards. Furthermore, the freshwater standards for several metals are expressed as the dissolved form of the metals, and seven metals have hardness -dependent equations. As a result, the Division will need site -specific effluent hardness data and instream hardness data, upstream of the discharge, for each facility monitoring these metals in order to calculate permit limitations. The metal of concern for this permit renewal is Zinc. To evaluate dissolved Zinc, a Reasonable Potential Analysis (RPA) was conducted using data reported on DMRs from November 2015 to March 2018. Results indicated a reasonable potential Page 10 of 12 DocuSign Envelope ID: 713338A4-3347-4D43-AA05-88EOF55E3FOD to exceed both the Acute and Chronic allowable concentrations for Zinc, 125.7 µg/L and 126.7 µg/L, respectively. The Acute value is typically used as the daily maximum limit and Chronic value is typically used as the monthly average limit. However, the Chronic value for Zinc is less stringent. The monthly average limit must be more stringent or equal to the daily maximum limit. Therefore, the daily maximum limit and monthly average limit for Zinc will be the Acute value as follows: Parameter Outfall Monthly Average Daily Maximum Limit Zinc 001 125.7 µg/L 125.7 µg/L Please note that on May 29, 2018 additional information was requested for Total Hardness. The total hardness data should have included five (5) days of Total Hardness (CaCO3 or (Ca + Mg)) data for the effluent and upstream of Outfall 001. This data would have been used in a recalculation of Zinc limits for the draft permit. However, no response was received within 60 calendar days [per 15A NCAC 2H.0107(b)]. Therefore, the permit renewal was drafted without the benefit of the requested Hardness data. Therefore, a default hardness of 25 mg/L was used to calculate effluent limits for Zinc as indicated above. 7. A schedule of compliance [Section A. (3.)] has been added for the Total Zinc limits in Section A. (L). Compliance with this limit shall commence approximately 48 months form the permit effective date. 8. Effluent and upstream quarterly monitoring for Total Hardness have been added. 9. Division personnel have reviewed and approved your permit modification request to reduce the effluent and influent monitoring frequencies for Biochemical Oxygen Demand (BOD5), Total Suspended Solids (TSS), Ammonia, and Fecal Coliform from daily to 2/week monitoring. The modification was based upon an evaluation of three years of facility effluent monitoring data. The facility's performance satisfies the criteria established in the "DWQ Guidance Regarding the Reduction of Monitoring Frequencies in NPDES Permits for Exceptionally Performing Facilities" as approved by the Director of the Division of Water Resources on October 22, 2012 and justifies reduced monitoring for these parameters. Please note that additional NPDES permit requirements will include: • Eligible facilities may be granted a reduction from existing permit monitoring frequencies to a 2/week minimum frequency for the four target parameters. Reductions will be made for both effluent and influent sampling. • Where monitoring is reduced to twice per week, it must occur on any two non- consecutive days during the calendar week (Sunday through Saturday). • Required monitoring frequency reductions establish new permit minimums for monitoring. As always, facilities may monitor more often than required in the permit. • If a reportable event, as defined by the permit [e.g., Part 11(E) (6 & 9)] occurs, any facility granted reduced monitoring frequencies will be encouraged to monitor on a daily basis until the episode is resolved. 10. Total Mercury must be monitored once during the permit cycle. Mercury monitoring is included to provide a database for future mercury management and TMDL evaluation. See Special Condition A. (2.).

However, application of the dissolved and hardness -dependent standards requires additional consideration in order to establish the numeric standard for each metal of concern of each individual discharge. The hardness -based standards require some knowledge of the effluent and instream (upstream) hardness and so must be calculated case -by -case for each discharge. Metals limits must be expressed as `total recoverable' metals in accordance with 40 CFR 122.45(c). The discharge -specific standards must be converted to the equivalent total values for use in the RPA calculations. We will generally rely on default translator values developed for each metal (more on that below), but it is also possible to consider case -specific translators developed in accordance with established methodology. RPA Permitting Guidance/WOBELs for Hardness -Dependent Metals - Freshwater The RPA is designed to predict the maximum likely effluent concentrations for each metal of concern, based on recent effluent data, and calculate the allowable effluent concentrations, based on applicable standards and the critical low -flow values for the receiving stream. If the maximum predicted value is greater than the maximum allowed value (chronic or acute), the discharge has reasonable potential to exceed the standard, which warrants a permit limit in most cases. If monitoring for a particular pollutant indicates that the pollutant is not present (i.e. consistently below detection level), then the Division may remove the monitoring requirement in the reissued permit. To perform a RPA on the Freshwater hardness -dependent metals the Permit Writer compiles the following information: • Critical low flow of the receiving stream, 7Q10 (the spreadsheet automatically calculates the 1 Q 10 using the formula 1 Q 10 = 0.843 (s7Q 10, cfs) 0.993 • Effluent hardness and upstream hardness, site -specific data is preferred • Permitted flow • Receiving stream classification 2. In order to establish the numeric standard for each hardness -dependent metal of concern and for each individual discharge, the Permit Writer must first determine what effluent and instream (upstream) hardness values to use in the equations. The permit writer reviews DMR's, Effluent Pollutant Scans, and Toxicity Test results for any hardness data and contacts the Permittee to see if any additional data is available for instream hardness values, upstream of the discharge. If no hardness data is available, the permit writer may choose to do an initial evaluation using a default hardness of 25 mg/L (CaCO3 or (Ca + Mg)). Minimum and maximum limits on the hardness value used for water quality calculations are 25 mg/L and 400 mg/L, respectively. If the use of a default hardness value results in a hardness -dependent metal showing reasonable potential, the permit writer contacts the Permittee and requests 5 site -specific effluent and upstream hardness samples over a period of one week. The RPA is rerun using the new data. Page 2 of 4 DocuSign Envelope ID: 713338A4-3347-4D43-AA05-88EOF55E3FOD Permit No. NCO021644 The overall hardness value used in the water quality calculations is calculated as follows: Combined Hardness (chronic) _ (Permitted Flow, cfs *Avg. Effluent Hardness, mg/L) + (s7Q10, cfs *Avg. Upstream Hardness, mg/L) (Permitted Flow, cfs + s7Q 10, cfs) The Combined Hardness for acute is the same but the calculation uses the IQ 10 flow. 3. The permit writer converts the numeric standard for each metal of concern to a total recoverable metal, using the EPA Default Partition Coefficients (DPCs) or site -specific translators, if any have been developed using federally approved methodology. EPA default partition coefficients or the "Fraction Dissolved" converts the value for dissolved metal at laboratory conditions to total recoverable metal at in -stream ambient conditions. This factor is calculated using the linear partition coefficients found in The Metals Translator: Guidance for Calculating a Total Recoverable Permit Limit from a Dissolved Criterion (EPA 823-B-96-007, June 1996) and the equation: Cdiss = 1 Ctotal 1 + { [Kpo] [ss('+a)] [10-6] } Where: ss = in -stream suspended solids concentration [mg/1], minimum of 10 mg/L used, and Kpo and a = constants that express the equilibrium relationship between dissolved and adsorbed forms of metals. A list of constants used for each hardness -dependent metal can also be found in the RPA program under a sheet labeled DPCs. 4. The numeric standard for each metal of concern is divided by the default partition coefficient (or site -specific translator) to obtain a Total Recoverable Metal at ambient conditions. In some cases, where an EPA default partition coefficient translator does not exist (ie. silver), the dissolved numeric standard for each metal of concern is divided by the EPA conversion factor to obtain a Total Recoverable Metal at ambient conditions. This method presumes that the metal is dissolved to the same extent as it was during EPA's criteria development for metals. For more information on conversion factors see the June, 1996 EPA Translator Guidance Document. 5. The RPA spreadsheet uses a mass balance equation to determine the total allowable concentration (permit limits) for each pollutant using the following equation: Ca = (s7Q 10 + Qw) (Cwgs)—(s7Q10) (Cb) Qw Where: Ca = allowable effluent concentration (µg/L or mg/L) Cwqs = NC Water Quality Standard or federal criteria (µg/L or mg/L) Cb = background concentration: assume zero for all toxicants except NH3* (µg/L or mg/L) Qw = permitted effluent flow (cfs, match s7Q 10) s7Q 10 = summer low flow used to protect aquatic life from chronic toxicity and human health through the consumption of water, fish, and shellfish from noncarcinogens (cfs) * Discussions are on -going with EPA on how best to address background concentrations Flows other than s7Q 10 may be incorporated as applicable: IQ 10 = used in the equation to protect aquatic life from acute toxicity Page 3 of 4 DocuSign Envelope ID: 713338A4-3347-4D43-AA05-88EOF55E3FOD Permit No. NCO021644 QA = used in the equation to protect human health through the consumption of water, fish, and shellfish from carcinogens 30Q2 = used in the equation to protect aesthetic quality 6. The permit writer enters the most recent 2-3 years of effluent data for each pollutant of concern. Data entered must have been taken within four and one-half years prior to the date of the permit application (40 CFR 122.21). The RPA spreadsheet estimates the 95th percentile upper concentration of each pollutant. The Predicted Max concentrations are compared to the Total allowable concentrations to determine if a permit limit is necessary. If the predicted max exceeds the acute or chronic Total allowable concentrations, the discharge is considered to show reasonable potential to violate the water quality standard, and a permit limit (Total allowable concentration) is included in the permit in accordance with the U.S. EPA Technical Support Document for Water Quality -Based Toxics Control published in 1991. 7. When appropriate, permit writers develop facility specific compliance schedules in accordance with the EPA Headquarters Memo dated May 10, 2007 from James Hanlon to Alexis Strauss on 40 CFR 122.47 Compliance Schedule Requirements. The Total Chromium NC WQS was removed and replaced with trivalent chromium and hexavalent chromium Water Quality Standards. As a cost savings measure, total chromium data results may be used as a conservative surrogate in cases where there are no analytical results based on chromium III or VI. In these cases, the projected maximum concentration (95th %) for total chromium will be compared against water quality standards for chromium III and chromium VI. 9. Effluent hardness sampling and instream hardness sampling, upstream of the discharge, are inserted into all permits with facilities monitoring for hardness -dependent metals to ensure the accuracy of the permit limits and to build a more robust hardness dataset. 10.

Purpose In its efforts to reduce the regulatory burden upon permittees while maintaining adequate compliance oversight over point source discharges, DWQ has developed the following guidance for the reduction of monitoring frequencies in NPDES permits for specific target parameters. Standard minimum NPDES monitoring frequencies are established in 15A NCAC 2B .0508 for discharges from facilities with specific Standard Industrial Classification (SIC) categories. However, 2B .0508(b)(1) states: "If it is demonstrated to the satisfaction of the Director that any of the tests and measurements, sampling points, or frequency of sampling requirements, as required in this Rule for a particular SIC group, are not applicable to the discharge of a particular water pollution control facility, or if it can be demonstrated that the objectives of this Section can be achieved by other acceptable means then such requirements may be waived or modified to the extent that the Director determines to be appropriate." This document identifies criteria to be used by DWQ that satisfies the regulatory standard for the allowance of reduced monitoring frequencies for facilities included in SIC 4952. This guidance applies to facilities with outstanding NPDES program compliance histories, exhibiting effluent discharges that are excellent in both quality and consistency. Such performance will demonstrate that compliance for particular parameters can be adequately evaluated with less monitoring. Facilities demonstrating consistent, long-term treatment performance at levels far below effluent limitations (<50%) may be considered for a reduction in monitoring from existing permit frequencies to a 2/week minimum frequency for the parameters BOD5, CBOD5 TSS, NH3-N and fecal coliform/enterococci (the "target parameters"). B. Approval Criteria Individual NPDES facilities shall submit a written request to modify their NPDES permit specifying which parameters are to be considered for reduced monitoring . Permit holders must include with their requests sufficient data, statistical analyses, and other information to support the justification for reduced monitoring. NPDES permit staff shall review the application and supporting information. Approval of reduced monitoring frequency shall be granted if all the criteria below are met: • The facility has no more than one civil penalty assessment for permit limit violations for each target parameter during the previous three years. • Neither the permittee nor any of its employees have been convicted of criminal violations of the Clean Water Act within the previous five years. • The facility is not currently under an SOC for target parameter effluent limit noncompliance. • The facility is not on EPA's Quarterly Noncompliance Report for target parameter limit violations. • For BOD5, CBOD5, TSS, NH3-N and TSS, the three year arithmetic mean of effluent data must be less than fifty percent of the monthly average permit limit. For fecal coliform or enterococci, the DocuSign Envelope ID: 713338A4-3347-4D43-AA05-88EOF55E3FOD three year geometric mean must be less than 50 percent of the monthly average permit limit. For parameters with summer and winter limits, an annual arithmetic mean of the seasonal limits may be used in the calculation. • With the exception of fecal coliform or enterococci, no more than 15 daily sampling results over the 3-year review period can be over 200% of the monthly average limit for BOD5, CBOD5, TSS, or NH3-N . Values associated with documented impacts of extreme weather or events beyond the control of the permittee will not be included. • For fecal coliform or enterococci, no more than 20 daily sampling results may be over 200% of the weekly average limit. Values associated with documented impacts of extreme weather or events beyond the control of the permittee will not be included. • For the four target parameters, sampling results shall not show more than two non -monthly average limit violations during the previous year. • Reduced effluent monitoring must not impair assessment of sensitive downstream uses, such as endangered species. C. Implementation After DWQ review and approval, the facility's NPDES permit will be reissued with reduced monitoring frequencies for qualified parameters. Additional NPDES permit requirements will include: • Eligible facilities may be granted a reduction from existing permit monitoring frequencies to a 2/week minimum frequency for the four target parameters. Reductions will be made for both effluent and influent sampling. • Where monitoring is reduced to twice per week, it must occur on any two non-consecutive days during the calendar week (Sunday through Saturday). • Required monitoring frequency reductions establish new permit minimums for monitoring. As always, facilities may monitor more often than required in the permit. • If a reportable event, as defined by the permit [e.g., Part 11 (E) (6 & 9)] occurs, any facility granted reduced monitoring frequencies will be encouraged to monitor on a daily basis until the episode is resolved. Monitoring frequency reduction from the minimum frequencies reductions established by the rules are based upon consistent, exceptional performance. DWQ may revoke on a case -by -case basis these reductions if the facility begins to perform in noncompliance with permit limits. If a facility's monitoring reduction for a specific parameter is removed through permit modification, reconsideration of monitoring frequency reduction will only occur three years following the revocation/permit modification action, or at the next permit renewal.
