Box 218 North Wilkesboro,North Carolina 28659 Subject: Draft NPDES Permit Renewal Permit NC0020761 Thurman Street WWTP Wilkes County Grade III Biological WPCS SIC Code 4952 Dear Mr. Hooper: Enclosed with this letter is a copy of the Draft NPDES permit renewal for your facility. Please review this draft carefully to ensure thorough understanding of the requirements and conditions it contains. There are several changes from the existing permit, including the following: • Based on the reasonable potential analysis (RPA) showing no reasonable potential to violate state water quality standards, the monitoring requirement for total silver has been removed from the permit [See A.(1)]. • Per 15A NCAC 02B .0508, monitoring frequencies for instream fecal coliform have been revised [See A.(1.)]. • The Division is implementing dissolved metals standards in all permits,per the 2016 revisions to State water quality standards. As such, 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 order to calculate permit limitations. Effluent hardness and instream hardness sampling,upstream of the discharge,have been added to the permit at a monitoring frequency of quarterly [See A.(1.)]. • Language has been added to Footnote 2 to account for influent and effluent abbreviations [See A. (1.)]. • Some of the wording has changed in Special Condition A. (2.), Chronic Toxicity Permit Limit,please review each paragraph carefully. • Special Condition A. (3.) has been modified to include the specific three years in which the Effluent Pollutant Scan shall be performed(2022, 2023, and 2024). In addition, at the end of the Special Condition, 2nd species Toxicity Testing Requirements for municipal permit renewals per Federal Regulations [40 CFR 122.21(j)(5)] have been added. • A notation was made concerning the Electronic Reporting Rule — NPDES Electronic Reporting Rule — Phase 2 Extension. EPA extended the Phase 2 deadline to December 21, 2025.

Page 7 of 11 Permit NC0020761 A.(4.) ELECTRONIC REPORTING OF DISCHARGE 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.) Signatory Requirements • Section D. (2.) Reporting • Section D. (6.) Records Retention • Section E. (5.) Monitoring Reports 1. Reporting Requirements[Supersedes Section D. (2.)and Section E. (5.) (a)1 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. The eDMR system may be accessed at:https://deq.nc.gov/about/divisions/water-resources/edmr. 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 following address: NC DEQ/ Division of Water Resources/ Water Quality Permitting Section ATTENTION: Central Files 1617 Mail Service Center Raleigh, North Carolina 27699-1617 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 21,2025,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). Page 8 of 11 Permit NC0020761 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. Information on EPA's NPDES Electronic Reporting Rule is found at: https://www.federalregister.gov/documents/2015/10/22/2015-24954/national-pollutant- discharge-elimination-system-npdes-electronic-reporting-rule Electronic submissions must start by the dates listed in the"Reporting Requirements" section above. 3. How to Request a Waiver from Electronic Reporting The permittee may seek a temporary electronic reporting waiver from the Division.
