Ms. Phillips: I am the compliance inspector for West Rowan High School WWTP in Rowan County, NC. The last Compliance Evaluation Inspection was conducted on May 3, 2017. It was noted during the subject inspection that this facility does not have chlorination (disinfection) of effluent before discharge into Withrow Creek (Class C waters in Yadkin River Basin). Sampling of the effluent was conducted back in 2005 with Fecal Coliform results of 1100 col/100ml. The treatment facility services a student population of 1,079 persons. With fecal coliform passing through the treatment facility, and a large service population, there is a high probability of pathogenic organisms being present in the effluent. It is therefore the recommendation of this Office that chlorination and dechlorination of effluent be added to the subject permit protect the health of downstream users. If you should have any questions in regards to this facility or require additional in ormation please contact me. Thank you Roberto L.

In particular, therWe_st Rowan_HS permit (single s pass sand filter) doenot require monitoring/adherence p _. to fecal coliform limits based on a_high_dilution, I had sampled this facility's effluent back in 2005 and the fecal coliform result was 11,000 col/100 ml.. I'm surprised the dilution ratio is that high due to the stream not being very wide or deep. In addition, we have a second wastewater treatment facility, Seven Cedars Mobile Home Park (NC0023191), that does not have to monitor/adhere to fecal coliform limits. This is an activated sludge wastewater treatment system and again, a high dilution allows for this. This facility is also in the permit renewal process and the receiving stream, Third Creek, appears to have fecal coliform issues in the stream segment that the discharge enters. I have recently sampled this facility's effluent that included a fecal coliform sample so hopefully I'll have a result soon. I've reviewed the Fecal Coliform Policy on the website and in my opinion, the Division should still require disinfection for these wastewater treatment facilities. At a minimum, effluent and instream fecal coliform monitoring should be required. Thanks for the notifications regarding the permit renewals and the opportunity to provide input.

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). If applicable, summarize any instream data and what instream monitoring will be proposed for this permit action: The current permit requires instream monitoring for Flow.

Compliance Summary Summarize the compliance record with permit effluent limits (past 5 years): There have been no enforcements at all since 2002, and no violations since 2005. In the past, the permit has lacked limits and monitoring for fecal coliform due to the receiving stream providing such dilution to the discharge that they are not required. There has also been no requirement for disinfection. Per Roberto Scheller and Corey Basinger at MRO, chlorination and de -chlorination was suggested to be added to the permit to protect the health of downstream users. Monitoring for fecal was also recommended and a study began Tuesday, November 27', 2018 and continued with a twice per week monitoring schedule for three weeks. The samples were then analyzed by a private lab, and evaluated by MRO. No modifications were made at this time, and will be discussed by John Hennessy and Julie Grzyb at a later time. Summarize the compliance record with aquatic toxicity test limits and any second species test results (past 5 years): N/A Summarize the results from the most recent compliance inspection: There is no record of any recent inspection. 6. Water Quality -Based Effluent Limitations (WQBELs) Dilution and Mixing Zones In accordance with 15A NCAC 2B.0206, the following stream flows 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/1 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: NA 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. Page 4 of 10 DocuSign Envelope ID: E69AFFF5-5C95-4FOF-BEE8-DCE43F7E9A7C Limitations for Total Residual Chlorine (TRC) are based on the NC water quality standard for protection of aquatic life (17 ug/1) and capped at 28 ug/l (acute impacts). Due to analytical issues, all TRC values reported below 50 ug/l are considered compliant with their permit limit. 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 NA 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) stream flows 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 NA. 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: NA • 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 Monitoring: 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 • 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 5 of 10 DocuSign Envelope ID: E69AFFF5-5C95-4FOF-BEE8-DCE43F7E9A7C 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: NA 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/l NA Table.

Technology -Based Effluent Limitations (TBELs) Municipals (if not applicable, delete and skip to Industrials) Are concentration limits in the permit at least as stringent as secondary treatment requirements (30 mg/l BOD5/TSS for Monthly Average, and 45 mg/l for BOD5/TSS for Weekly Average). NA If NO, provide a justification for alternative limitations (e.g., waste stabilization pond). NA Are 85% removal requirements for BOD5/TSS included in the permit? NA If NO, provide a justification (e.g., waste stabilization pond). NA Industrials (if not applicable, delete and skip to next Section INA Describe what this facility produces: List the federal effluent limitations guideline (ELG) for this facility: If the ELG is based on production or flow, document how the average production/flow value was calculated: For ELG limits, document the calculations used to develop TBEL limits: Table. TBEL Development per NA Pollutant Daily Maximum BPT/BAT (lb/1000 lb) Daily Maximum Limit (lb /d) Monthly Average BPT/BAT (lb/1000 lb) Monthly Average Limit (lb/d) If any limits are based on best professional judgement (BPJ), describe development: NA Document any TBELs that are more stringent than WQBELs: NA Document any TBELs that are less stringent than previous permit: NA 8. Antidegradation Review (New/Expanding Discharge): The objective of an anti -degradation 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 anti -degradation review in accordance with 15A NCAC 2B.0201. Each applicant for a new/expanding NPDES permit Page 7 of 10 DocuSign Envelope ID: E69AFFF5-5C95-4FOF-BEE8-DCE43F7E9A7C 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 213.0500; 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: A. Table.
