CHRONIC TOXICITY MONITORING (QUARTERLY) All samples collected should be from a representative discharge event. There shall be no discharge of floating solids or visible foam in other than trace amounts. A. (2.) CHRONIC TOXICITY PASS/FAIL PERMIT MONITORING (QUARTERLY) [15A NCAC 02B .0500 et seq.] The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Mysidopsis bahia at an effluent concentration of 20 %. The permit holder shall perform at a minimum, quarterly monitoring using procedures described below to establish compliance with the permit condition. The tests will be performed during the months of February, May, August, and November. 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. The test procedure will be based on EPA Method 1007.0, Mysid, Mysidopsis bahia, Survival, Growth, and Fecundity Test, as described in Short -Term Methods for Estimating the Chronic Toxicity of Effluents and Receiving Waters to Marine and Estuarine Organisms, Third Edition, EPA -821-R-02-014. The procedure will be performed as written with the following exceptions: • The test treatments will consist of a control and a 20% effluent concentration. • Mortality for pass/fail tests will be evaluated using the t test described in Section 11.3 in Methods for Measuring the Acute Toxicity of Effluents to Freshwater and Marine Organisms, Fifth Edition. EPA -821-R-02-012, October 2002, applying an alpha level of 0.05. • The growth endpoint for pass/fail tests will be determined using Appendix G of Short - Term Methods for Estimating the Chronic Toxicity of Effluents and Receiving Waters to Marine and Estuarine Organisms, Third Edition, EPA -821-R-02-014, October 2002, applying an alpha level of 0.01. • Mortality and growth endpoints for multiple -concentration tests will be determined using hypothesis testing as described in EPA Method 1007.0, Mysid, Mysidopsis bahia, Survival, Growth, and Fecundity Test, as described in Short -Term Methods for Estimating the Chronic Toxicity of Effluents and Receiving Waters to Marine and Estuarine Organisms, Third Edition, EPA -821-R-02-014, October 2002. • Fecundity will not be evaluated. 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. For pass/fail results, report using the parameter code TGP3E and the DWR Form AT -4 (original), which is to be sent to the address below.

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. Upon submission of a valid test, this monthly test requirement will revert to quarterly in the months specified above. 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. A. (3.) INSTREAM SAMPLE LOCATIONS [15A NCAC 02B.0500 et seq.] The Permittee shall collection grab samples at the designated locations and frequency during a continuous discharge event after a minimum of 1 hour of continuous discharge has occurred. Every effort to replicate the same sample location is requested. To provide a point of comparison the required effluent grab sample should be collected at the same time.

(4) 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 Recerds Retention Monitoring Reports 1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)1 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: Page 6of8 Permit NC0083089 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; 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: http://www2.gpa.gov/compliance/final-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 Page 7of8 Permit NC0083089 shall not exceed 5 years and shall thereupon expire. At such time, monitoring data and reports shall be submitted electronically to the Division unless �`ie 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-reso--irces/edmr 4. Sanatory 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. (I 1.)(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.
