NORTH CAROLINA Director Environmental Quality August 2,2022 Mr.Tyler W.Thomas,Town Manager Town of Pembroke 100 Union Chapel Rd Pembroke,North Carolina 28372 Subject: Final NPDES Permit Renewal&Expansion Permit NC0027103 Pembroke WWTP Robeson County Grade III Biological WPCS SIC Code 4952 Dear Mr. Thomas: Division personnel have reviewed and approved your application for renewal of the subject permit. Accordingly,we are forwarding the attached NPDES permit.This permit is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency dated October 15, 2007 (or as subsequently amended). No changes were made to the draft sent to you on June 6,2022; this final permit maintains the following significant changes identified in the letter sent on June 6,2022: • Based on the Town's request to modify the permit to authorize a plant expansion to 2.0 MGD, review and approval of the submitted Engineering Report/Environmental Information Document for the proposed expansion,an Effluent Limits and Monitoring Requirements sheet for 2.0 MGD has been added to the permit [See A.(2.)]. • A component list for the proposed 2.0 MGD expansion flow tier has been added to the Supplement to Permit Cover Sheet. • As part of the expansion review, updated streamflows at the discharge were calculated by USGS at Division request. The resulting updated streamflows were used in updating a set of speculative limits that were originally calculated for the 2.0 expansion flow in 2013. As a result, the whole effluent toxicity test limit has been revised from 1.7% effluent to 3.0% effluent at 1.33 MGD [See A. (1.)] and a 4.5%limit was added at 2.0 MGD [See A. (2.)]. • The Town reported Total Silver at less than detection,with detection levels<5.0 µg/L,and< 3.0 µg/L in the submitted Effluent Pollutant Scan results. The Town's allowable discharge concentrations for Total Silver are 1.0 µg/L at 1.33 MGD and 0.7 µg/L at 2.0 MGD. DWR's laboratory identifies the target Practical Quantification Limits (PQLs) for silver is 1.0 µg/L. DE ..

(1.)and A.(2.)]. • Based on NPDES guidance regarding the reduction of monitoring frequencies in NPDES permits for exceptionally performing facilities, monitoring requirements for BOD, TSS, Ammonia and Fecal Coliform has been maintained at 2/week at 1.33 MGD [See A. (1.)]. • Based on DWR Instream Fecal Coliform Monitoring Guidance,since the facility discharges to a Class B water, instream fecal coliform has been added to the permit[See A.(1.)and A. (2.)]. • Some of the wording has changed in Special Condition A.(3.),Chronic Toxicity Permit Limit, please review each paragraph carefully. • Special Condition A. (4.) has been modified to include the specific three years in which the Effluent Pollutant Scan shall be performed(2024,2025,and 2026). • 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. • Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program reports. The requirement to continue reporting discharge monitoring data electronically using the NC DWR's Electronic Discharge Monitoring Report(eDMR)interne application has been added to your NPDES permit [See A. (5.)]. • Parameter codes have been added to the Effluent Limitations and Monitoring Requirements for both flow tiers[See A.(1.)and A.(2.)]as well as the Effluent Pollutant Scans[See A.(4.)]. • Regulatory citations have been added to the permit. Pretreatment updates in response to NPDES permit renewal: • On March 30, 2023, 180 days after the effective date of this NPDES permit renewal, the Town is required to submit to the Division a written technical evaluation of the need to revise local limits (i.e., an updated IWS/HWA-AT/L-STMP, or documentation of why is not needed). This action may include revising, updating, or adding to the list of SIUs regardless of timeframe. o Submit the updated Short-Term Monitoring Plan(STMP) • If there are new industries within the service area, submit an updated Industrial Waste Survey(IWS) • Review pollutants of concern (POCs) and update the STMP to reflect pollutants in industrial user permits(IUPs)and sludge management permit. • Update the POC PQLs to recommended levels: • Arsenic(As)at 2.0 µg/L • Cadmium(Cd)at 0.5 µg/L • Lead(Pb) at 2.0 µg/L • Molybdenum(Mo)at 10.0 at µg/L • Silver(Ag)at 1.0 at 2.0 µg/L o As part of the local limits assessment, please submit the updated Headworks Analysis(HWA).

Test data shall be complete, accurate, include all supporting chemical/physical measurements and all concentration/response data, and be certified by laboratory supervisor and ORC or approved designate signature.Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream. Should there be no discharge of flow from the facilityduringa month in which toxicitymonitoringis g required, the permittee will complete the information located at the top of the aquatic toxicity(AT)test form indicating the facility name,permit number,pipe number,county,and the month/year of the report with the notation of"No Flow" in the comment area of the form. The report shall be submitted to the Water Sciences Section at the address cited above. Should the Permittee fail to monitor during a month in which toxicity monitoring is required,monitoring will be required during the following month. Assessment of toxicity compliance is based on the toxicity testing quarter,which is the three-month time interval that begins on the first day of the month in which toxicity testing is required by this permit and continues until the fmal day of the third month. Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water Resources indicate potential impacts to the receiving stream,this permit may be re-opened and modified to include alternate monitoring requirements or limits. If the Permittee monitors any pollutant more frequently than required by this permit, the results of such monitoring shall be included in the calculation&reporting of the data submitted on the DMR& all AT Form submitted. NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism survival, minimum control organism reproduction, and appropriate environmental controls, shall constitute an invalid test and will require immediate follow-up testing to be completed no later than the last day of the month following the month of the initial monitoring.

Additional Toxicity Testing Requirements for Municipal Permit Renewal. Please note that Municipal facilities that are subject to the Effluent Pollutant Scan requirements listed above are also subject to additional toxicity testing requirements specified in Federal Regulation 40 CFR 122.21(j)(5).The US EPA requires four (4) toxicity tests for a test organism other than the test species currently required in this permit. The second species tests should be conducted either quarterly for a 12-month period prior to submittal of the permit renewal application,or four tests performed at least annually in the four and one- half year(4'/2)period prior to the application.Samples should be collected with one quarterly toxicity test each year,and must represent seasonal variation[i.e.,do not sample in the same quarter every year]. These tests shall be performed for acute or chronic toxicity, whichever is specified in this permit. The multiple species toxicity test results shall be filed with the Aquatic Toxicology Branch at the following address: North Carolina Division of Water Resources Water Sciences Section/Aquatic Toxicology Branch 1621 Mail Service Center Raleigh,North Carolina 27699-1621 Or results can be sent to the email:ATForms.ATB@ncdenr.gov. Contact the Division's Aquatic Toxicology Branch at 919-743-8401 for guidance on conducting the additional toxicity tests and reporting requirements.Results should also be summarized in Part E(Toxicity Testing Data) of EPA Municipal Application Form 2A,when submitting the permit renewal application to the NPDES Permitting Unit.

ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS [NCGS 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)j 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 monthly electronically using eDMR.The eDMR system allows permitted facilities to enter monitoring data and submit monthly 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 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.

Electronic Submissions In accordance with 40 CFR 122.41(1)(9),the pennittee must identify the initial recipient at the time of each electronic submission. The pennittee 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 five(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/edmr 4. Signatory Requirements(Supplements Section B.(11.)(b)and Supersedes Section B.(11.)(d)l 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.
