Box 3729 Sanford, NC 27331-3729 Dear Mr. Czar: ROY COOPER Governor MICHAEL S REGAN Seci etai), S JAY ZIMMERMAN Da ectoi Subject: Draft NPDES Permit Renewal Permit NCO024147 Big Buffalo WWTP Lee County Class IV Facility SIC code 4952 Enclosed with this letter is a copy of the draft NPDES permit renewal for your facility. Please review this draft carefully to ensure thorough understanding of the requirements and conditions it contains. There are several changes from the existing permit, including the following: The NC 2007-2014 Water Quality Standard (WQS) Triennial Review was approved by the NC Environmental Management Committee (EMC) on November 13, 2014. The US EPA subsequently approved the WQS revisions on April 6, 2016 with some exceptions. The NC Division of Water Resources NPDES Permitting Unit is required to implement the new dissolved metal standards in all permits public noticed after April 6, 2016. The new standards for most metals include acute standards. Further, the freshwater standards for several metals are expressed as the dissolved form of the metals, and seven metals have hardness -dependent equations. As a result, the NPDES Permitting Unit will need site-specific effluent hardness data and instream hardness data, upstream of the discharge, for each facility monitoring these metals in order to calculate permit limitations. Effluent hardness and instream hardness sampling, upstream of the discharge, has been added to this permit at a monitoring frequency of quarterly. See special condition A. (1) Effluent Limitations and Monitoring Requirements for effluent and instream sampling requirements. • Total copper did not show reasonable potential to violate NC WQS but it did exceed 50% of the allowable discharge limit. Monitoring for total copper has been maintained at a frequency of quarterly and shall be sampled in conjunction with hardness above. • Please be advised that four toxicity tests should be conducted for an organism other than your normal test species during your permit cycle. The results for the four toxicity tests State of North Carolina I Environmental Quality I Water Resources 1617 Marl Service Center I Raleigh, North Carolina 27699-1617 919 807 6300 Page 12 must be submitted with your next renewal application. This condition has been added to your permit under Special Condition A. (3). • The limits and monitoring of mercury have been removed from Effluent Limitations and Monitoring Requirements based on the TMDL evaluation. Sampling for mercury shall be conducted during the 3 effluent pollutant scans [see special condition A. (3)]. Please note the mercury must be sampled using method 1631E as outlined in Special Condition A. (3). Currently you are using EPA method 245. 1, which is not compliant with Effluent Pollutant Scan requirements. • Special condition A. (4) has been added to require a Mercury Minimization Plan (MMP) based on the statewide mercury TMDL approved by EPA in 2012. • The special condition A. (5) Instream Monitoring Requirements has been removed. Instream monitoring is now maintained in special condition A. (1) Effluent Limitations and Monitoring Requirements. Instream monitoring stations at Cumnock Bridge and at Highway 15-501 have been added, but are not required as long as membership in the Upper Cape Fear River Basin Association is maintained. • Special conditions for the 6.8 MGD flow phase limitations, monitoring requirements, and quarterly toxicity test at 32% has been removed since the facility has expanded to 12 MGD. • Instream monitoring for fecal coliform has been removed since the receiving water body is not impaired for fecal coliform, is not classified for primary recreation, and the facility has had no fecal coliform violations. • Monitoring frequencies for CBOD, TSS, and fecal coliform have been reduced to 2/Week in accordance with DWR policy for Reduction of Monitoring Frequencies in NPDES Permits for Exceptionally Performing Facilities, October 22, 2012. • The monitoring for silver, zinc, and chloride have been removed based on the results of the RPA which showed no reasonable potential to exceed water quality standards. • The total residual chlorine limit has been removed since chlorination and dichlorination facilities have been removed and UV is now used for disinfection. • Effluent Pollutant Scan frequency has changed from annual to 3 times per permit cycle [see A. (3)]. • Parameter characteristic codes have been added in special condition A. (1). • An updated outfall map has been included. • The NPDES Standard Conditions (Parts II, III, and IV) are not included with this draft. They can be found at the following link if you would like to review them in conjunction with this draft permit. http: //ncdenr. s3 . amazonaws. com/s3 fs- public/Water%20Qual-�ty/Surface%20Water%20Protection/NPDES/MIS C/NPDES %20 St andard%20Conditions-Boilerplate-DWR-SWP-NPDES-20150410.pdf • Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program reports. The final NPDES Electronic Reporting Rule was adopted Page 13 and became effective on December 21, 2015. The requirement to begin reporting discharge monitoring data electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR) internet application has been added to your final NPDES permit.

Effluent hardness sampling should be performed in conjunction with testing for metals. 8. The permittee shall sample insLream hardness upstream of the facility's discharge. The sample shall be representative of the hardness in the receiving stream. If the permittee is a member of a monitoring coalition program, sampling for instream hardness may be waived as long as the monitoring coalition agrees to sample hardness at the nearest upstream location, at a minimum frequency of quarterly, and the permittee has obtained approval from DWR-NPDES Permitting Unit that the upstream station being monitored by the coalition is representative of the receiving stream for this discharge. The permittee is responsible for submitting instream hardness test results with its permit renewal application package. If coalition membership is cancelled or the coalition terminates instream hardness sampling at the approved station, the permittee will immediately notify the Division and resume sampling for instream hardness upstream of its discharge. THERE SHALL BE NO DISCHARGE OF FLOATING SOLIDS OR VISIBLE FOAM IN OTHER THAN TRACE AMOUNTS. 4of11 Permit NCO024147 A. (2) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY) [15A NCAC 02B.0200 et seq.] The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent concentration of 45%. The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, or subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised- December 2010) or subsequent versions. The tests will be performed during the months of March, June, September and December. These months signify the first month of each three-month toxicity testing quarter assigned to the facility. Effluent sampling for this testing must be obtained during representative effluent discharge and shall be performed at the NPDES permitted final effluent discharge below all treatment processes. If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the two following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -December 2010) or subsequent versions. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form (MR -1) for the months in which tests were performed, using the parameter code TGP3B for the pass/fail results and THP311 for the Chronic Value. Additionally, DWR Form AT -3 (original) is to be sent to the following address: Attention: North Carolina Division of Water Resources Water Sciences Section/Aquatic Toxicology Branch 1621 Mail Service Center Raleigh, NC 27699-1621 Completed Aquatic Toxicity Test Forms shall be filed with the Water Sciences Section no later than 30 days after the end of the reporting period for which the report is made. 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 facility during a month in which toxicity monitoring is 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 5of11 Permit NCO024147 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 final 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. 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. F A. (3) EFFLUENT POLLUTANT SCAN [NCGS 143-215.1 (b)] The permittee shall perform a total of three (3) Effluent Pollutant Scans for all parameters listed below.

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 122.210)(5) and EPA Municipal Application Form 2A. 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 period prior to the application. The second species tests must be multiple concentration (5 concentrations plus the control) These tests shall be performed for acute or chronic toxicity, whichever is specified in this permit. POTWs performing NPDES chronic Ceriodaphma testing should perform chronic Fathead minnow testing. POTWs performing NPDES acute Fathead Minnow testing should perform acute Cenodaphnia testing. POTWs performing NPDES chronic Mysid shrimp testing should perform chronic Silverside Minnow testing. The second 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 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. A. (4) MERCURY MINIMIZATION PLAN (MMP) [NCGS 143-215.1 (b)] The permittee shall develop and implement a mercury minimization plan during this permit term. The MMP shall be developed within 180 days of the NPDES Permit Effective Date, and shall be available 7of11 Permit NCO024147 for inspection on-site. A sample MMP was developed through a stakeholder review process and has been placed on the Division website for guidance (http://deq.nc.gov/about/divisions/water- resources/water-resources-permits/wastewater-branch/npdes-wastewater-permits, under Model Mercury Minimization Plan). The MMP should place emphasis on identification of mercury contributors and goals for reduction. Results shall be summarized and submitted with the next permit renewal. Performance of the Mercury Minimization Plan will meet the requirements of the TMDL (Total Maximum Daily Load) for mercury approved by USEPA on October 12, 2012, unless and until a Waste Load Allocation specific to this facility is developed and this NPDES permit is amended to require further actions to address the Waste Load Allocation A. (5) PERMIT RE -OPENER: SUPPLEMENTARY NUTRIENT MONITORING [NCGS 143-215.1 (b)] Pursuant to N.C. Gen. Stat. Section 143-215.1 and the implementing rules found in Title 15A of the North Carolina Administrative Code, Subchapter 2H, specifically, 15A NCAC 2H.0112 (b) (1) and 2H.0114 (a), and Part II sections B-12 and B-13 of this Permit, the Director may reopen this permit to require supplemental nutrient monitoring of the discharge. 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. A. (6) CALCULATION OF MASS LOADS [NCGS 143-215.1 (b)] The permittee shall calculate monthly and seasonal TN (or TP) Loads as follows: • Monthly TN (or TP) Load (pounds/month) = TN (or TP) x TMF x 8.34 where: TN (or = the average Total Nitrogen or (Total Phosphorus) concentration TP) (mg/L) of the daily composite samples collected during the month TMF = the Total Monthly Flow of wastewater discharged during the month (MG/month) 8.34 = conversion factor, from (mg/L x MG) to pounds • Seasonal TN (or TP) Load (pounds/season) = Sum of the 7 Monthly TN (or TP) Loads for the summer season, April I — October 31 (214 days). The permittee shall report Total Nitrogen and Total Phosphorus concentrations for each sample and the monthly mass loadings in the appropriate discharge monitoring report for each month. The Effluent Nutrients Worksheet (DWQ Form NW 1 s(10/10)) shall be completed and submitted with the April through October discharge monitoring reports, during each calendar year, identifying compliance or non-compliance with NPDES permit nutrient loading limitations. 8of11 Permit NCO024147 A. (7) ELECTRONIC REPORTING OF 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.) • Section D. (2.) • Section D. (6.) • Section E. (5.) Signatory Requirements Reporting Records Retention Monitoring Reports 1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.)

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. Until such time that the state's eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation (CROMERR), permittees will be required to submit all discharge monitoring data to the state electronically using eDMR and will be required to complete the eDMR submission by printing, signing, and submitting one signed original and a copy of the computer printed eDMR 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 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 mailing address above. 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; 9of11 Permit NC0024147 • 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.federalre ister.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 temperary 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://deq.nc.gov/about/divisions/water-resources/edmr 4.
