Governor ,, ELIZABETH S.BISER `fttaw�" Secretary S.DANIEL SMITH NORTH CAROLINA Director Environmental Quality December 07, 2021 Mr. Eddie Thomas Town Manager Town of Broadway PO Box 130 Broadway,NC, 27505 Subject: DRAFT NPDES PERMIT NC0059242 Broadway WWTP Grade II Biological WPCS [15A NCAC 08G .0302] Lee County Dear Mr. Thomas: Enclosed with this letter is a copy of the draft permit for your facility. Please review the draft very carefully to ensure thorough understanding of the conditions and requirements it contains. Your permit is among several in the Cape Fear River Basin that the Division has targeted for expedited renewal. This draft contains the following changes from the existing permit: • The supplement to permit cover page has been updated to include stream index and HUC of outfall location. • The facility's classification has been added above the effluent monitoring table. • The language in section A (3.) has been updated to be consistent with current federal guidelines for electronic reporting. • Ammonia limits have been updated to align with current ammonia toxicity strategy. Previous limits seem to have been based on an old wasteload allocation. Current EPA instream criteria for ammonia is 1.0 mg/L during summer, and 1.8 mg/L during winter.A calculation to determine limits was conducted using the summer and winter flow of Daniels Creek,and the WWTP's design flow. Based on the limited dilution available in Daniels Creek, new limits have been assigned as: o Summer- 2.0 mg/L monthly average; 6.0 mg/L weekly average o Winter- 3.1 mg/L monthly average; 9.3 mg/1 weekly average Limits were similarly adjusted for the second flow tier. 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). The conditions are the same as in your current permit. The latest version is available at https://bit.ly/2BZ4xxx and can be viewed online or downloaded as a PDF file. With this notification, the Division will solicit public comment on this draft permit by publishing a notice in newspapers having circulation in the general Lee County area, per EPA requirements.

Permit NC0059242 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.) fall 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. 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. Permit NC0059242 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-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. 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.
