Director Mr. Glenn Kennedy, District Manager Fork Township Sanitary District PO Box 1515 Goldsboro, NC 27533 Dear Permittee: NORTH CAROLINA Enirkwun n[a/Quaary October 1, 2024 Subject: Draft NPDES Permit NCO087726 Fork Township Water Treatment Plant Physical Chemical WPCS Wayne County The Division has reviewed your request to renew the subject permit. Enclosed with this letter is a copy of the draft permit for your facility. Please review this draft carefully to ensure your thorough understanding of the information, conditions, and requirements it contains. The draft permit includes the following significant changes from the existing permit: ➢ Removed item #3 from the Supplement to Permit Cover Sheet. ➢ Updated footnotes to the effluent table in Section A. (1.). ➢ Added effluent Hardness and instream Hardness, upstream of the facility's discharge, monitoring to the table in Section A. (I.) with corresponding footnotes. These parameters were added to comply with the current NCDEQ water treatment plant strategy. ➢ Reporting for Total Nitrogen (TN) now includes the constituent parameters used in calculating TN. Total Kjeldahl Nitrogen (TKN) and Nitrate + Nitrite Nitrogen (NO3-N + NO2-N) have been added to the effluent table in Section A. (I.) with a corresponding footnote. The Sample Type for Total Nitrogen has been updated from "Grab" to "Calculated". ➢ Added an effluent flow limit to the effluent table in Section A. (1.) to comply with the current NCDEQ water treatment plant strategy. The Division has determined that the volume of Water Treatment Plant (WTP) discharges has the potential to impact receiving waters and should be controlled statewide. The Division is moving to reinstate limits in permit renewals and include limits for new WTP permits. A flow limit of 0.03 MGD has been added to this permit. ➢ Added Duration of Flow monitoring to the effluent table in Section A. (1.) to comply with the current NCDEQ water treatment plant strategy for instantaneous flow monitoring. The measurement frequency was changed from 2/month to "Once per Discharge" because a facility should be reporting flow from all discharge events ➢ Removed iron monitoring from the effluent table in Section A (1.), since there is no longer a water quality standard for iron. ➢ Combined the original sections A (1.) and A (2.) to add the radiological components to the bigger effluent table. ➢ Added the eDMR codes for every parameter to the effluent table in Part 1. Section A. (I.). ➢ Added parameter units to the effluent table in Part I. Section A. (I.). ➢ Updated eDMR language for electronic data submission in Part 1. A. (3). ➢ Updated the map. �7,,(� North Carolina Department of Environmentales Quality I Division of Water Resources es JL 512 North Salisbury Street 11617 Mail Service Groner I Ralelgh.Nurih Carollna276941617 g1q.7oT9o0o Page 2 of 2 NPDES Permit NC0087726 The NPDES standard conditions (Parts II, III, and IV) that are a part of the permit are not included in this draft document (cover, map, and Part I).

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. Reoortin¢ Requirements ISuoersedes Section D. (2.) and Section E. (5.) (a)l 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 intemet. The eDMR system may be accessed at: https://deg.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. Monitoring results obtained during the previous month(s) shall be summarized for each month and reported via the eDMR system no later than the last calendar day of the month following the completed reporting period. 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: Page 5 of 7 NPDES Permit NC0087726 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(I)(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: htttys://www.federalre ig ster.yov/documents/2015/10/22/2015- 24954/national-pollutant-discharee-elimination-system-nodes-electronic-reporting-rule Electronic submissions must start by the dates listed in the "Reporting Requirements" section above. 3. 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 transferrable. 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. rrov/about/divisions/water-resources/edmr Page 6 of 7 NPDES Permit NC0087726 4.
