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/l 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). If applicable, summarize any instream data and what instream monitoring will be proposed for this permit action: NA. Is this facility a member of a Monitoring Coalition with waived instream monitoring (YIN): NO. Name of Monitoring Coalition: NA. 5. Compliance Summary Summarize the compliance record with permit effluent limits (past 5 years): See Attachment D: Monitoring Report Violations Nov2013 to Oct2018, 1 page. No NOVs or NODS were noted. 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: The last facility inspection conducted on 11/06/2018 reported that the facility appeared to be clean and well maintained. See Attachment E: Inspection Report 11/06/2018, 5 pages. 6. Water Quality -Based Effluent Limitations (WQBELs) Dilution and Mixin.. Zones Page 3 of 6 DocuSign Envelope ID: E8F5795C-4481-4A8B-AA44-8E4885D0731F In accordance with 15A NCAC 213.0206, 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/1 for Municipals) may be appropriate if deemed more stringent based on dilution and model results. If permit 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/1(summer) and 1.8 mg/1(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/1(acute impacts). Due to analytical issues, all TRC values reported below 50 ug/1 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. NCG59000 sets the daily maximum limit for TRC at 17 µg/l. Reasonable Potential Analysis (RPA) for Toxicants — NA. 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 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 Page 4 of 6 DocuSign Envelope ID: E8F5795C-4481-4A8B-AA44-8E4885D0731F 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. Describe proposed permit actions based on mercury evaluation: NA. Other TMDL/Nutrient Management Strategy Considerations If applicable, describe any other TMDLs/Nutrient Management Strategies and their implementation within this permit: Under the current general permit NCG590000 nutrient monitoring is not required for Greensand technology that discharges to freshwater. Other WQBEL 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: NA. If applicable, describe any water quality standards variances proposed in accordance with NCGS 143- 215.3(e) and 15A NCAC 2B.0226 for this permit renewal: NA. 7. Technology -Based Effluent Limitations (TBELs) — 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. Page 5 of 6 DocuSign Envelope ID: E8F5795C-4481-4A8B-AA44-8E4885D0731F 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: NC0088498 is to be converted to COC NCG590024.

Coverage (1.) Eligibility of Coverage a. Existing Greensand Water Treatment Plants (WTPs) with individual NPDES permits and new facilities seeking a NPDES permit for a greensand water purification system utilizing Iron and/or Manganese removal systems are eligible for coverage under this general permit. Backwash wastewaters from similar activities such as sand filtration or systems utilizing calcite filtration are eligible and covered under the Greensand WTP effluent requirements section in this general permit. b. Existing Conventional WTPs with a wastewater discharge resulting from water purification facilities with filter backwash, sedimentation basin washdown, and decant from water treatment facilities are eligible for coverage under this general permit. (2.) Limitations on Coverage a. Although this general permit does not cover the following types of discharges, other permits such as an individual NPDES permit, an alternate general permit, or other approval from the Division may be obtained. This permit does not authorize discharges from Water Treatment Plants with the following: • Discharges that are mixed with other process wastewaters. • Discharges to waters classified as High Quality Waters (HQW) or Outstanding Resource Waters (ORW). • Discharges from water purification systems using Membrane Treatment (Reverse Osmosis) or Ion Exchange. • Discharges that would adversely affect a Federal or State listed endangered or threatened species or its critical habitat. • Discharges of pollutants to an impaired waterbody in excess of the wasteload allocation specified in an EPA -Approved TMDL (Total Maximum Daily Load). • Discharges from new Conventional WTPs proposing a discharge to surface waters. b. New Conventional WTPs proposing a discharge to surface waters shall be covered under an individual permit for at least one permit cycle. Upon permit renewal, if an evaluation of the facility's wastewaters shows no need for additional limitations or requirements beyond what is contained in this general permit, then the permittee will be considered for coverage. c. Conventional WTPs proposing to expand existing facilities shall submit a Notice of Intent (NOI) permit application with the proposed expansion/treatment details and an Engineering Alternative Analysis for Division review and approval in order to obtain coverage for the expansion under this permit and receive a revised Certificate of Coverage (CoC). d. This permit does not authorize discharges that the Division has determined to be or which may reasonably be expected to be contributing to a violation of a water quality standard (as defined in the "Red Book" or NC Administrative Code 15A NCAC 02B .0100, .0200, and .0300). e. If the Division determines at any time that the discharge is causing or contributing to a violation of water quality standards or if the Division has any other grounds for modifying or revoking this permit, the Division may require corrective action or require the discharge be permitted differently in accordance with Part II, Section B of this permit. The Division may deny coverage under this permit and require submittal of an application for an individual NPDES permit based on a review of the Notice of Intent (NOI) or other information. f. Whole Effluent Toxicity (WET) test results for the past three years shall be reviewed for existing or expanding Conventional WTPs applying for coverage under this general permit. Permittees with WET test results showing potential for aquatic toxicity may be denied coverage under this general permit which includes a WET limitation of "Pass". (3.) Transfer Coverage from Other Permits Upon issuance of this general permit, all existing and active individual permits for Greensand and Conventional type WTPs will automatically be considered for coverage under this general permit as permit renewal applications are received.
