J it's , Governor \ MICHAEL S.REGAN Secretary LINDA CULPEPPER NORTH CAROLINA Director Environmental Quality August 6, 2019 - Ms. Jacqueline A. Jarrell, Operations Chief Charlotte Water 5100 Brookshire Blvd. Charlotte,North Carolina 28216 Subject: Draft NPDES Permit Renewal Permit NC0036277 McDowell Creek WWTP Mecklenburg County Grade IV Biological WPCS SIC Code 4952 Dear Ms. Jarrell: 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: • Based on the reasonable potential analysis(RPA) showing no reasonable potential to violate state water quality standards, the monitoring requirements for Copper and Zinc have been removed from the permit [See A. (1)]. • Based on the Mercury TMDL evaluation, no Mercury Minimization Plan (MMP) is required during this permit cycle. Therefore, the MMP Special Condition was removed from the permit. • The facility reported Cadmium and Thallium at less than detection, with detection levels< 1.0 µg/L, and< 5.0 µg/L respectively. The facility's allowable discharge concentrations are 1.8 µg/L and 2.2 µg/L for Cadmium and Thallium,respectively. DWR's laboratory identifies the target Practical Quantification Limits(PQLs) for Cadmium as 0.5 µg/L and Thallium as 2.0 µg/L. 15A NCAC 2B .0505 (e) (4)requires that all test procedures must produce detection and reporting levels that are below the permit discharge requirements and all data generated must be reported to the approved detection level or lower reporting level of the procedure. If no approved methods are determined capable of achieving detection and reporting levels below permit discharge requirements, then the approved method with the lowest detection and reporting level must be used. The facility should use sufficiently sensitive test methods for all pollutants, including when performing Effluent Pollutant Scans. No limit or monitoring requirement will be added to the permit at this time. However, failure to analyze to the approved detection level or lower reporting level may result in a limit for Cadmium and Thallium during the next renewal. �D E -4 NorthNorth Carolina DepartmentSalisburyStreet1 of 1617 EnvironmentalMailServiceCenter I Raleigh Quality I Division North of WaterCarolina Resources 512 , 27699-1617 owe. a a :..Maa+\ /'' 919.707.9000 • Some of the wording has changed in Special Condition A. (2), Chronic Toxicity Permit Limit. Please review each paragraph carefully. • Special Condition A. (3)has been modified to include the specific three years in which the Effluent Pollutant Scan shall be performed(2020, 2021, 2022). In addition, at the end of the Special Condition, 2nd Species Toxicity Testing Requirements for municipal permit renewals per Federal Regulations [40 CFR 122.21 (j)(5)] have been added. • 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)internet application has been added to your NPDES permit[See Special Condition A. (4)]. • Parameter codes have been added to the Effluent Limitations and Monitoring Requirements [See A. (1)] • Regulatory citations have been added to the permit. 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 except that agency and division names have been updated.

Page 4 of 10 Permit NC0036277 A. (2) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY) [15A NCAC 02B.0200] The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent concentration of 90%. 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 January,April,July,and October. 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 fmal 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 TIIP3B 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 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. 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.

Page 6 of 10 Permit NC0036277 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 multiple 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. 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 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) ELECTRONIC REPORTING OF 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)I 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. 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 Page 7of10 Permit NC0036277 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; • 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/20 15/10/22/2015-24954/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. Page 8 of 10 Permit NC0036277 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)1 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.
