CHRONIC TOXICITY MONITORING(QUARTERLY) [15A NCAC 02B .0500 et seq.] The permittee shall conduct quarterly chronic toxicity tests using test procedures outlined in the"North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure,"Revised December 2010, or subsequent versions. The effluent concentration defined as treatment two in the procedure document is 90%. The testing shall be performed as a Ceriodaphnia dubia 7day pass/fail test. 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 shall be performed at the NPDES permitted final effluent discharge below all treatment processes. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form(MR-1) for the month in which it was performed,using the parameter code TGP3B. Additionally, DWQ Form AT-1 (original) is to be sent to the following address: Attention: North Carolina Division of Water Quality Environmental Sciences Section 1621 Mail Service Center Raleigh,N.C. 27699-1621 Completed Aquatic Toxicity Test Forms shall be filed with the Environmental 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 and accurate and include all supporting chemical/physical measurements performed in association with the toxicity tests, as well as all dose/response data. 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 Environmental Sciences Section at the address cited above. Should the permittee fail to monitor during a month in which toxicity monitoring is required, then monthly monitoring will begin immediately. 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 Quality 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 Forms submitted. Page 4 of 6 Permit NC0083348 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.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS [NCGS 143-215.1 (b)] Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and specify that, if a state does not establish a system to receive such submittals, then permittees must submit DMRs electronically to the Environmental Protection Agency(EPA). The Division anticipates that these regulations will be adopted and is beginning implementation in late 2013. 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 [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 DENR/DWR/Information Processing Unit ATTENTION: Central Files/eDMR 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. Page 5 of 6 Permit NC0083348 Requests for temporary waivers from the NPDES electronic reporting requirements 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 using eDMR. Temporary waivers shall be valid for twelve(12)months and shall thereupon expire. At such time, DMRs shall be submitted electronically to the Division unless the permittee re-applies for and is granted a new temporary waiver by the Division. Information on eDMR and application for a temporary waiver from the NPDES electronic reporting requirements is found on the following web page: http://portal.ncdenr.org/web/wq/admin/bog/ipu/edmr 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. • 2.
