TEMPORARY MEANS OF DISINFECTION [NCGS 143-215.1(a)] In the event that the wastewater treatment plant's ultraviolet(UV) disinfection system should fail, underperform, or otherwise be removed from effective service, the permittee or his agent should immediately inform the Surface Water Protection Section staff of the Wilmington Regional Office of this development and discuss temporary, alternate means for disinfection of the effluent. If chlorine compounds are used as temporary means of disinfection,the total residual chlorine (TRC) concentration of the effluent must be monitored on a daily basis while this method of disinfection is in use and values must be reported on the discharge monitoring report. TRC in the effluent may not exceed 17 µg/L; therefore, dechlorination methods may also be necessary to ensure protection of water quality in the receiving stream. The Division shall consider all effluent TRC values reported below 50 µg/L to be in compliance with the permit. However, the Permittee shall continue to record and submit all values reported by a North Carolina certified laboratory(including field certified), even if these values fall below 50 µg/L. Use of a disinfection system other than the permitted UV system during circumstances not deemed as emergency and/or temporary(replacement of lamps, lamp cleaning or maintenance, etc.)will be considered a violation of the terms of this permit. A. (3.) 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)[ 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 Page 4 of 6 DocuSign Envelope ID: 1 E84CDE3-93E8-4516-B901-313B6BD8A109 Permit NC0045276 Grade I Biological Water Pollution Control System[15A NCAC 08G.0302] 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 21,2020,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. 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-rile 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. 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 Page 5 of 6 DocuSign Envelope ID: 1 E84CDE3-93E8-4516-B901-313B6BD8A109 Permit NC0045276 Grade I Biological Water Pollution Control System[15A NCAC 08G.0302] 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/edmr 4. Signatory Requirements [Supplements Section B. (11.) (b) and Supersedes Section B. (11.) (d)I 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.
