(4.)PERMIT RE-OPENER: SUPPLEMENTARY NUTRIENT MONITORING/TMDL IMPLEMENTATION [NCGS 143-215.1 (b)] Pursuant to N.C. General Statutes Section 143-215.1 and the implementing rules found in the North Carolina P g Administrative Code at 15A NCAC 2H.0112 (b)(1)and 2H.0114(a)and Part II sections B-12 and B-13 of this permit, the Director of DWQ may reopen this permit to require supplemental nutrient monitoring of the discharge. The purpose of the additional monitoring will be to support water quality modeling efforts within the Cape Fear River Basin and shall be consistent with a monitoring plan developed jointly by the Division and affected stakeholders.In addition,the results of water quality modeling may require that limits for total nitrogen and total phosphorus be imposed in this permit upon renewal. The Division may, upon written notification to the permittee, re-open this permit in order to incorporate or modify effluent limits,monitoring and reporting requirements, and other permit conditions when it deems such action is necessary to implement TMDL(s)approved by the USEPA. A. (5.) ELECTRONIC REPORTING - 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. Page 6 of 9 Permit NC0065480 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: • 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. Information on EPA's NPDES Electronic Reporting Rule is found at: https://www.federalregister.gov/documents/2015/10/22/2015-24954/national-pollutant-discharge- el imination-system-npdes-electronic-reporting-rul e Electronic submissions must start by the dates listed in the "Reporting Requirements" section above. 3. How to Request a Waiver from Electronic Reporting Page 7 of 9 Permit NC0065480 The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an electronic reporting waiver, apermittee must first submit an electronic reporting waiver request to P gP g q 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://deq.nc.gov/about/divisions/water-resources/edrnr 4. Signatory Requirements [Supplements Section B.(11.) (b)and Supersedes Section B.(11.) 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. For more information on North Carolina's eDMR system,registering for eDMR and obtaining an eDMR user account, please visit the following web page: http://deq.nc.gov/about/divisions/water-resources/edmr Certification. Any person submitting an electronic DMR using the state's eDMR system shall make the following certification [40 CFR 122.22]. NO OTHER STATEMENTS OF CERTIFICATION WILL BE ACCEPTED: "I certify, under penalty of law, that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted.

Records Retention [Supplements Section D. (6.)1 The permittee shall retain records of all Discharge Monitoring Reports, including eDMR submissions. These records or copies shall be maintained for a period of at least 3 years from the date of the report. This period may be extended by request of the Director at any time [40 CFR 122.41].
