REGAN Secrnmy LINDA CULPEPPER Subject: Final NPDES Permit Renewal Permit NCO020451 West Jefferson W WTP Ashe County Facility Class 11 SIC Code 4952 Dear Mr. Price: ha,rim Director Division personnel have reviewed and approved your application for renewal of the subject permit. Accordingly, we are forwarding the attached NPDES permit. This permit is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency dated October 15, 2007 (or as subsequently amended). Please note that the receiving stream is listed as impaired for benthos on the North Carolina 2014 303(d) Impaired Waters List. Addressing impaired waters is a high priority with the Division, and instream data will continue to be evaluated. If there is noncompliance with permitted effluent limits and stream impairment can be attributed to your facility, then mitigative measures may be required. The following changes were made to the draft permit sent to you on November 15, 2017: • The influent flow meter and spray -irrigation system were removed from the components list per comments received from the Town. The final permit maintains the following significant changes identified in the letter sent on November 15, 2017: • The NC 2007-2014 Water Quality Standards (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 NPDES Permitting Unit 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. Further, 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 NPDES Permitting Unit will need site -specific effluent hardness data and instream hardness data, upstream of the discharge, for each facility monitoring these metals in State of North Carolina I Environmental Quality I Water Resources 1617 Mail service Center I Releiyh, North Carolina 27699-1617 919 807 6300 Page 12 order to calculate permit limitations. Effluent hardness and instream hardness sampling, upstream of the discharge, has been added to this permit at a monitoring frequency of quarterly. See Special Condition A. (1.) Effluent Limitations and Monitoring Requirements. • Based on a reasonable potential analysis using the new WQS discussed above along with submitted hardness data from June 2017, total copper showed reasonable potential to violate NC WQS with chronic and acute limits calculated at 37 µg/L and 52 µg/L respectively. Monthly monitoring with monthly average and daily maximum limits have been added to this permit. See Special Condition A. (1.). • A reasonable potential analysis for cyanide, cadmium, beryllium, and zinc did not demonstrate reasonable potential to violate WQS and monitoring for those parameters has been removed from this permit. • Selenium showed reasonable potential to violate WQS in a limited dataset (<8 samples) with only one sample exceeding the standard, therefore monitoring has been added at a frequency of quarterly. See Special Condition A. (1.). • Review of effluent data shows all samples for beryllium were reported at less than detection with detection levels ranging from <1 µg/L to <50 jig/L. In accordance with 15A NCAC 2B .0500 all test procedures must produce detection and reporting levels that are below the permit discharge requirements and all data generated must be reported to the approved detection level or lower reporting level of the procedure. Currently, DWR's laboratory identifies the Practical Quantitation Limit (PQL) for beryllium at <5 µg/L. The allowable discharge concentration for beryllium at your facility is 11.6 µg/L as a monthly average. Therefore, future sampling for beryllium as part of the facility's Effluent Pollutant Scans should sample beryllium to the lower reporting level of the procedure which is <5 µg/L. • Due to adoption of a statewide mercury TMDL in 2012 and no reasonable potential to violate WQS, mercury monitoring has been removed in this permit. • Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program reports. The requirement to continue reporting discharge monitoring data electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR) internet application has been added to your NPDES permit. See Special Condition A. (4.) If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt of this letter. This request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-6714). Unless such demand is made, this decision shall be final and binding. Please note that this permit is not transferable except after notice to the Division. The Division may require modification or revocation and reissuance of the permit. This permit does not affect the legal requirements to obtain other permits which may be required by the Division of Water Resources or any other Federal, State, or Local governmental permits that may be required.

CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY) [I 5A NCAC 02B.0200] The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent concentration of 56%. The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, or subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised- December 2010) or subsequent versions. The tests will be performed during the months of January, April, July, and October. These months signify the first month of each three-month toxicity testing quarter assigned to the facility. Effluent sampling for this testing must be obtained during representative effluent discharge and shall be performed at the NPDES permitted final effluent discharge below all treatment processes. H the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the two following months as described in "North Carolina Phase H Chronic Whole Effluent Toxicity Test Procedure" (Revised -December 2010) or subsequent versions. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the parameter code TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally, DWR Form AT-3 (original) is to be sent to the following address: Attention: North Carolina Division of Water Resources Water Sciences Section/Aquatic Toxicology Branch 1621 Mail Service Center Raleigh, NC 27699-1621 Completed Aquatic Toxicity Test Forms shall be filed with the Water Sciences Section no later than 30 days after the end of the reporting period for which the report is made. Test data shall be complete, accurate, include all supporting chemical/physical measurements and all concentration/response data, and be certified by laboratory supervisor and ORC or approved designate signature. Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream. Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating the facility name, permit number, pipe number, county, and the month/year of the report with the notation of "No Flow" in the comment area of the form. The report shall be submitted to the Water Sciences Section at the address cited above Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be required during the following month. Assessment of toxicity compliance is based on the toxicity testing quarter, which is the three month time interval that begins on the first day of the month in which toxicity testing is required by this permit and continues until the final day of the third month. 4 of 10 Permit NCO020451 Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water Resources indicate potential impacts to the receiving stream, this permit may be re -opened and modified to include alternate monitoring requirements or limits. NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism survival, minimum control organism reproduction, and appropriate environmental controls, shall constitute an invalid test and will require immediate follow-up testing to be completed no later than the last day of the month following the month of the initial monitoring. 5of10 Permit NCO020451 A. (3.) EFFLUENT POLLUTANT SCAN (Municipal POTWs) [G.S. 143-215.1(b)] The permittee shall perform a total of three (3) Effluent Pollutant Scans for all parameters listed below. One scan must be performed in each of the following years: 2018, 2019, and 2020. Analytical methods shall be in accordance with 40 CFR Part 136 and shall be sufficiently sensitive to determine whether parameters are present in concentrations greater than applicable standards and criteria. Samples should be collected with one quarterly toxicity test each year, and must represent seasonal variation [i.e., do not sample in the same quarter every year]. Unless otherwise indicated, metals shall be analyzed as "total recoverable."

The report shall be submitted to the following address: NC DEQ / DWR / Central Files,1617 Mail Service Center, Raleigh, North Carolina 27699-1617. Additional Toidcity Testing Requirements for Municipal Permit Renewal. Please note that Municipal facilities that are subject to the Effluent Pollutant Scan requirements listed above are also subject to additional toxicity testing requirements specified in Federal Regulation 40 CFR 122.216)(5). The US EPA requires four (4) toxicity tests for a test organism other than the test species currently required in this permit. The multiple species tests should be conducted either quarterly for a 12-month period prior to submittal of the permit renewal application, or four tests performed at least annually in the four and one half year period prior to the application. These tests shall be performed for acute or chronic toxicity, whichever is specified in this permit. The multiple species toxicity test results shall be filed with the Aquatic Toxicology Branch at the following address: North Carolina Division of Water Resources Water Sciences Section/Aquatic Toxicology Branch 1621 Mail Service Center Raleigh, North Carolina 27699-1621 Contact the Division's Aquatic Toxicology Branch at 919-743-8401 for guidance on conducting the additional toxicity tests and reporting requirements. Results should also be summarized in Part E (Toxicity Testing Data) of EPA Municipal Application Form 2A, when submitting the permit renewal application to the NPDES Permitting Unit. A. (4.) ELECTRONIC REPORTING OF MONITORING REPORTS [G.S. 143-215.1(b)] Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program reports. The final NPDES Electronic Reporting Rule was adopted and became effective on December 21, 2015. NOTE: This special condition supplements or supersedes the following sections within Part II of this permit (Standard Conditions for NPDES Permits): • Section B. (11.) • Section D. (2.) • Section D. (6.) • Section E. (5.) Signatory Requirements Reporting Records Retention Monitoring Reports 1. Reporting Requirements (Supersedes Section D. (2.) and Section E. (5.) (a)) 7 of 10 Permit NC0020451 The permittee shall report discharge monitoring data electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR) internet application. Monitoring results obtained during the previous month(s) shall be summarized for each month and submitted electronically using eDMR. The eDMR system allows permitted facilities to enter monitoring data and submit DMRs electronically using the internet. Until such time that the state's eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation (CROMERR), permittees will be required to submit all discharge monitoring data to the state electronically using eDMR and will be required to complete the eDMR submission by printing, signing, and submitting one signed original and a copy of the computer printed eDMR to the following address: NC DEQ / Division of Water Resources / Water Quality Permitting Section ATTENTION: Central Files 1617 Mail Service Center Raleigh, North Carolina 27699-1617 If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility being physically located in an area where less than 10 percent of the households have broadband access, then a temporary waiver from the NPDES electronic reporting requirements may be granted and discharge monitoring data may be submitted on paper DMR forms (MR 1,1.1, 2, 3) or alternative forms approved by the Director. Duplicate signed copies shall be submitted to the mailing address above. See "How to Request a Waiver from Electronic Reporting" section below. Regardless of the submission method, the first DMR is due on the last day of the month following the issuance of the permit or in the case of a new facility, on the last day of the month following the commencement of discharge. Starting on December 21, 2020, the permittee must electronically report the following compliance monitoring data and reports, when applicable: • Sewer Overflow/Bypass Event Reports; • Pretreatment Program Annual Reports; and • Clean Water Act (CWA) Section 316(b) Annual Reports. The permittee may seek an electronic reporting waiver from the Division (see "How to Request a Waiver from Electronic Reporting" section below). 2. Electronic Submissions In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the time of each electronic submission. The permittee should use the EPA's website resources to identify the initial recipient for the electronic submission. Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity (EPA or the state authorized by EPA to implement the NPDES program) that is the designated entity for receiving electronic NPDES data [see 40 CFR 127.2(b)]. EPA plans to establish a website that will also link to the appropriate electronic reporting tool for each type of electronic submission and for each state. Instructions on how to access and use the appropriate electronic reporting tool will be available as well.

How to Reauest a Waiver from Electronic Reporting The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to the Division. Requests for temporary electronic reporting waivers must be submitted in writing to the Division for written approval at least sixty (60) days prior to the date the facility would be required under this permit to begin submitting monitoring data and reports. The duration of a temporary waiver shall not exceed 5 years and shall thereupon expire. At such time, monitoring data and reports shall be submitted electronically to the Division unless the permittee re -applies for and is granted a new temporary electronic reporting waiver by the Division. Approved electronic reporting waivers are not transferable. Only permittees with an approved reporting waiver request may submit monitoring data and reports on paper to the Division for the period that the approved reporting waiver request is effective. Information on eDMR and the application for a temporary electronic reporting waiver are found on the following web page: http://deg .nc. gov/about/divisions/water-resources/edmr 4. Signatory Requirements (Supplements Section B. (11.) (b) and Supersedes Section B. (11.) (d)1 All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part II, Section B. (11.)(a) or by a duly authorized representative of that person as described in Part II, Section B. (11.)(b). A person, and not a position, must be delegated signatory authority for eDMR reporting purposes. For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR user account and login credentials to access the eDMR system.

Basic Facility Information Facility Information Applicant/Facility Name: Town of West Jefferson/West Jefferson WWTP Applicant Address: PO Box 490, West Jefferson, NC 28694 Facility Address: 335 Clearwater Drive, West Jefferson, NC 28694 Permitted Flow: 0.5 MGD Facility Type/Waste: MINOR 98% Domestic 2% Industrial Facility Class: Class II Treatment Units: Mechanical bar Screen, grit removal, dual channel oxidation ditches, secondary clarifier, tertiary filters, UV disinfection, post aeration basin, aerobic sludge digester, water reclamation spray -irrigation Pretreatment Program (Y/1) Yes County: Ashe Region Winston-Salem Briefly describe the proposed permitting action and facility background: The Town of West Jefferson has applied for NPDES permit renewal, and submitted a renewal application dated August 27, Page 1 of 11 2015. This facility serves a population of 1,170 residents and operates a pretreatment program with 1 Significant Industrial User (SHD. The receiving stream (1+1 designation) drains to ORW waters. Previous permits used rule 15A NCAC 02B .0225(e)(4)(B)(C) to assign water quality based effluent limits (WQBEL) and treatment standards for the facility. This stream was reclassified in 2010 and is now subject to 15A NCAC 02B .0225(e)(14) which uses 15A NCAC 02B .0224 as the basis for developing WQBELs and treatment standards. That rule states that expanding facilities are to meet certain treatment requirements unless they expand with no increase in permitted pollutant loading. Since the facility had expanded with no increase in permitted pollutant loading the treatment required in 15A NCAC 02B .0224(1)(b)(i)-(vii) does not apply, and using one-half the normal standard for toxicants is not applied in this permit as it was done previously. 2.

Instream Data Summary Instream monitoring may be required in certain situations, for example: 1) to verify model predictions when model results for instream dissolved oxygen (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: The current permit requires instream monitoring for dissolved oxygen, conductivity, and temperature. Review of instream data for the past two years indicates that the dissolved oxygen standard of 6.0 mg/L was maintained, and there was little variation between upstream and downstream stations. The average downstream temperature was 0.65°C warmer than upstream, with 116 out of 199 samples exceeding the 0.5°C differential for trout waters. Effluent temperatures are consistently higher than either upstream or downstream stations. The Winston-Salem Regional Office will be alerted to the situation and investigate any compliance issues with the temperature Page 3 of 11 standard. Upstream conductivity averaged 238 umhos/cm and downstream averaged 298 umhos/cm. This draft permit maintains the same instream monitoring requirements. Figure 1. Instream Parameters.

Compliance Summary Summarize the compliance record with permit effluent limits (past 5 years): The facility reported three BOD violations from June 2014 through May 2015 and one now violation in 2013. Summarize the compliance record with aquatic toxicity test limits and any second species test results (past 5 years): The facility passed 18 of 19 quarterly chronic toxicity tests. The failed test in April 2014 was followed by two monthly multi -dilution tests, both of which passed. Four passing second species chronic toxicity tests were performed from February through May 2017. Summarize the results from the most recent compliance inspection: The last facility inspection conducted in October 2015 found the facility in compliance, well -run, and recommended reissuance of the permit. 6. Water Quality -Based Effluent Limitations (WQBELs) Dilution and and Mixing In accordance with 15A NCAC 213.0206, the following streamflows are used for dilution considerations for development of WQBELs: 1Q10 streamflow (acute Aquatic Life); 7Q10 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 Page 4 of 11 • 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. If permit limits are more stringent than TBELs, describe how limits were developed: Limitations for BOD are assigned by rule 15A NCAC 02B .0225(e)(14) for waters draining to the North Fork New River Outstanding Resource Waters (ORW) area. 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 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: New ammonia - nitrogen monthly average limits of 1.6 mg/L summer and 3.6 mg/L winter will be applied to this permit based on an updated NH3 Wasteload Allocation. New weekly averages using the above chronic/acute criteria will also be applied. 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 %2 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 January 2013 and May 2017. 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: Copper. Page 5 of 11 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: None. 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: Arsenic, Beryllium, Cadmium, Total Chromium, Cyanide, Lead, Molybdenum, Nickel, Silver, Zinc. 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: None. 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: Selenium. 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. Toxicily 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: This is a Minor POTW, and a chronic WET limit at 56% effluent will continue at a quarterly frequency. 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 ilg/L) 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 ilg/L) and/or if any individual value exceeds a TBEL value of 47 rlg/L. Page 6 of 11 Table 2. Mercury Effluent Data Summary. 2013 2014 2015 2016 2017 # of Samples 4 4 4 4 4 Annual Average, n 1.4 0.6 0.5 0.5 0.9 Maximum Value, n 2.70 1.05 0.50 0.60 1.04 TBEL, n 47 WQBEL, n 10.6 Describe proposed permit actions based on mercury evaluation. Since no annual average mercury concentration exceeded the WQBEL, and no individual mercury sample exceeded the TBEL, no mercury limit is required. The facility is < 2 MGD so no AE%IP will be required. Other TMDL/Nutrient Management Strategy Considerations If applicable, describe any other TMDLs/Nutrient Management Strategies and their implementation within this permit: NA Other WQBEL Considerations If applicable, describe any other parameters of concern evaluated for WQBELs: NA If applicable, describe any special actions (High Quality Water (HQW) or Outstanding Resource Water (OR FP)) this receiving stream and classification shall comply with in order to protect the designated waterbody: This area drains to the North Fork New River ORW in the New River (15A NCAC 02B .0225 (e)(14)) with new and expanded wastewater discharges required to comply with BOD=5 mg/L, NH3-N=2 mg/L and TSS=10 mg/L(trout waters). In addition, all ORW waters are subject to the HQW DO >_ 6 mg/L water quality standard. If applicable, describe any compliance schedules proposed for this permit renewal in accordance with 1 SA NCAC 2H. 0107( 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 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) 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). YES If NO, provide a justfcation for alternative limitations (e.g., waste stabilization pond). NA Are 85% removal requirements for BOD5/TSS included in the permit? YES If NO, provide a justification (e.g., waste stabilization pond). NA Page 7 of 11 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): Yes If YES, confirm that antibacksliding provisions are not violated: Based on a reasonable potential analysis of 2013-2017 data, the previous cyanide limit will be removed. Furthermore, the receiving stream was reclassified in late 2010 and using one-half of the WQS for toxicants is no longer applicable in this facility's case. 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. Page 8 of 11 12.Summary of Proposed Permitting Actions: Table 3.

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. 1. To perform a RPA on the Freshwater hardness -dependent metals the Permit Writer compiles the following information: • Critical low flow of the receiving stream, 7Q 10 (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 Permit No. NCO020451 r 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) + (s7010, cfs *Avg. Upstream Hardness, m /&) (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 T h *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(t+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 = (s7010 + Qw) (Cwgs) — (s7Q 10) (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: 1Q10 = used in the equation to protect aquatic life from acute toxicity Page 3 of 4 Permit No. NC0020451 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 pennit in accordance with the U.S. EPA Technical Support Document for Water Quality -Based Toxics Control published in 1991. 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. 8. 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.

Use a default value ofzS mg/L if no hardness data is available. Second, the Dissolved Metal allocations are divided by the Translators to determine the Total Metals that can be allocated tothe Fermittes. These Total Metals values are automatically Inserted Into Table 2 and are the allowable Total Metal allocations determined for the Pancreas prior to allowing for dilution. See Input sheet Table 2. The gnat were and chronic values shown under the RPA sheet are the Total Metal values listed in Table 2 divided by the acute and chronic IWC, respectively. The Translation used in the freshwater RPA are the Partition Coefgclents published by US EPA In 1983. They are TSS dependent equations and can be found listed with the WW hardness dependent equations under the sheet IaWed Equations. A feed T5S value of 10 mg/L is usad to olcuum the Translatorvaluss.

Box 490 West Jefferson, NC 28694 SUBJECT: Compliance Evaluation Inspection (CEI) Town of West Jefferson WWTP NPDES Permit # NCO020451 Ashe County Dear Mr. Price: Donald R. van der Vaart Secretary On October 8, 20.15 a CEI was performed by George Smith. Mr. Charles Call, ORC, was present for the inspection. The inspection is comprised of an overall evaluation in order to document compliance and noncompliance of: facilities equipment, capability to meet effluent limits, and terms & conditions with the NPDES permit. Permit The permit became effective August 1, 2011 and expires March 31, 2016. A correct copy is kept on file. Records & Reports The Repair & Maintenance log is a three ring binder that contains the following sections: pump stations, influent pumps, grit removal, automatic barscreen, traveling bridge on tertiary filter, blowers, clarifiers, oxidation ditch, ultraviolet disinfecting lamps, sludge pump, sludge truck, generator. The Town keeps excellent maintenance records. The chain -of -custody reports are complete, and they clearly document the sample conditions. , The facility documents process control in the oxidation ditch of MLSS, dissolved oxygen, temperature, conductivity, pH, microscopic examination, and clarifier blanket height. These daily logs were in very good order. The Annual Performance Report for 2014 was received in the Raleigh office on February 11, 2015. Facility Site Review The 3 mm automatic barscreen, grit removal, and pre -aeration were all operating properly. All three influent pumps are functioning properly. The oxidation ditch had a light brown color and a good earthy odor indicating good treatment. It is unknown at this time whether the control gate at the - inner ring can be adjusted or is properly supported. Currently it is set to give the highest water level, and therefore the highest dissolved oxygen. The gate will be tested during the winter months when dissolved oxygen from the rotators are not critically needed. All four rotating biological contactors were operating. 450 W Hanes Mill Rd., Suite 300, Winston-Salem, NC 27105 Phone: 336-776-98001 Internet: www.ncdenr.gov The effluent from the new and old circular clarifiers was clear, with a very minor amount of pin flock over the weirs. No algae present. Both skimmers were operating. Both secondary clarifiers are operated in an excellent manner. The effluent from the tertiary sandfilters was clear with no surface solids or scum noticed. The UV disinfection unit appeared to be properly working. The UV lamps were operating and had sufficient power. The post aeration unit was working, and there were no solids present. Flow Measurement The flow recording charts are kept on file for the required minimum of three years. Continuous flow measurement at the plant is performed using a 90' V-notch weir with a Sigma 980 ultrasonic device mounted before the effluent weir. The flow measuring device was calibrated by Milco Calibrations, LLC on November 24, 2014. Paperwork documentation was maintained in the file. The instantaneous flow was 177 gallons/minute (0.250 MGD). Laboratory The municipal lab received field certification (#5284) for Conductivity, Dissolved Oxygen, pH, and Temperature. Conductivity is performed using an Orion Model 122. The Orion Star AT21 pH meter is routinely calibrated and documented using a two -point calibration (pH 4 & 10) and a midrange check (pH 7). The YSI Model 55 field meter is used to measure for Dissolved Oxygen. Air calibration is performed. Temperature is recorded with an Orion 122, and calibrated, which is NIST traceable. The lab measures and documents the field data in an excellent manner. The addition of a good microscope, Olympus, Model CX41 is a very good tool that will aide in identifying biological problems before they become a serious issue. This microscope has proven to be a good investment. Effluent/Receiving Waters The effluent from the POTW was crystal clear with no solids, no color, or no odor. The visual appearance of the effluent is considered to be outstanding at the time of the inspection. The unnamed tributary to Little Buffalo Creek, Class C-Trout + waters showed no adverse impacts. Operations & Maintenance The following Town personnel operate the facility: Charles Call, ORC, Grade IV; Jody Walters, Back-up ORC, Grade 1; and Mr. Brandon Patrick, Maintenance, Grade III. The staff perform their operation & maintenance duties in an outstanding_ manner. The MLSS is approximately 3800 mg/L and the dissolved oxygen was 3.80 mg/L. Self -Monitoring Program A review of the monthly self -monitoring reports from January 2014 through July 2014 revealed a monthly average violation for BOD during June 2014. The Town currently performs influent composite sampling with an Isco Model 3700 FR. A sample aliquot of 250 ml is collected every 10,080 gallons. This complies with the flow proportion sample requirement. The Town currently performs effluent composite sampling with an Isco Model 3700 FR. A sample aliquot of 250 ml is collected every 9,900 gallons. This complies with the flow proportion sample requirement. The influent & effluent sample compartments were documented at VC with MIST traceable temperature reading. The upstream and downstream measurements are performed at the proper locations. Sludge Disposal The digesters are approximately 30% full. This is considered excellent operations of the plant, especially going into the winter months. A screw press was tested during the winter of 2014-2015. It will be available if needed this winter. I &- Brantley Price indicated that a grant proposal was submitted to the Appalachian Regulatory Commission for a dewater project for 851K. This includes a screw press and sewer collection system projects. The inspection is satisfactory. The quality of the effluent is excellent and the plant personnel are considered to perform their jobs in an excellent mantier.

Total storage ability is approximately 250,000 gallons. Thorough aeration and mixing occur within the digesters using coarse air diffusers. Measurement of PH is performed using Orion Star A121 PH meter. An activity log is kept documenting dates of land application. We are using the 30 Day Bench Scale to satisfy the PSRP and Vector attraction reduction criteria. Samples are analyzed on the sludge per 503 regulations and soil samples are taken on the application sites annually. Once the contents of the digester meet PSRP and Vector attraction criteria, sludge is removed from the unit and land applied by surface method. Sludge can be transferred from any other digester to prepare it for surface application. Post Office Box 490 of S.
