Accordingly, we are forwarding the attached NPDES discharge 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). The following significant changes have been incorporated into this renewal: • Based on the Permitting Guidelines for Statewide Mercury TMDL, the Mercury Minimization Plan special condition will be added to the permit (Please see A. (4)). The mercury monitoring will be removed from the permit. The facility will continue mercury monitoring through PPA. • Monitoring for Cu and Zn has been reduced to quarterly based on the statistical analysis of the effluent data. • Monitoring for Cyanide has been reduced to monthly based on the statistical analysis of the effluent data. • Daily maximum limit for cyanide has been increased to 40.5 µg/L based on the procedures for statistical analysis established by the Division. • Weekly average limit for cyanide has been changed to the monthly average limit in response to the EPA requirements. • Proposed federal regulations require electronic submittal of all discharge monitoring reports (DIVIRs) 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. 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Phone 91907-630011nternet www.ncwaterquality.org An Equal Opportunity 1 Affirmative Action Employer— Made in part by recycled paper The requitement to begin 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.

However, effluent values below 50 ug/L will be treated as zero for compliance purposes. There shall be no discharge of floating solids or foam visible in other than trace amounts. A. (2.) CHRONIC TOXICITY PERMIT LIMIT (QRTRLY) The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent concentraticn of 50.0 %. The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the "North Carolina Cenodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or "North Carolina Phase IJ Chronic Whole Effluent Toxicity Test Procedure" (Re-6sed-February 1998) or subsequent versions The tests will be performed during ,he months of January, April, July, and October. Effluent sampling for this testing 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 -February 1998) or subsequent versions. The chronic value for multiple concentration tests will be determined using the geometric mean of the highest concentration having no detectable impairment of reproduction or survival and the lowest concentration that does have a detectable impairment of reproduction or survival. The definition of "detectable impairment," collection methods, exposure regimes, and further stafistical methods are specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) 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 ir- which tests were performed, using the parameter code TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally, DWR Form AT -3 (original) is to be sent to the following address: Attention: NC DENR / DWR / Water Sciences Section 1621 Mail Service Center Raleigh, North Carolina 27699-1621 Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch 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 Environmental Sciences Branch at the address cited above. Should the permtttee fail to monitor during a month in which toxicity monitoring is required, monitoring will be required during the following month Should any test data from this monitoring requirement or tests performed by Page 4 of 8 ,Plant ♦IndustryFlows • HWA data period •JanuaryI • ' • --- ---------- ---------- ---------- 0.738 1 0.005 0.024 1 0.012 1 0.143 Plant Avg.

Non SIU Flow: Based on the POTW annual average (0.7378 MGD) minus average SIU Flow (.184 MGD) NPDES Permit Limits: Based on NPDES Permit No. NC0020338, effective 7/11/14, expires 11/30/2018. Design Criteria The design criteria for TSS is being used to derive a more conservative loading value vs. NPDES Pass-Thru loading value. Removal Rates Removal Rates for BOD, TSS, Ammonia, Copper, Nickel, Zinc, Total Nitrogen, Total Phosphorus and Mercury are based on DMR/LTMP data and are Site Specific. Removal Rates for Arsenic, Cadmium, Chromium, Cyanide, Lead, Molybdenum, Selenium, and Silver are based on literature values. % detection values were used for all BDL's. Removed 6 Hg(245.1) results from EFF. Data set to improve removal rate %. This still left 12 (1631 Hg) data point to use for calculations. Inhibition Values All of the inhibition values are based on literature values. Sludge Criteria Sludge criteria is based on Class B sludge limits and actual sludge data. Required portions of the 2014-2016 Sludge reports are attached. Acreage was adjusted due to WWTP and WTP utilizing the same sites. Math included on the Sludge data sheet. HASL worksheet values are filled in using the required (2016) data, but are not being utilized. Uncontrollable Based on the mass balance between Influent and SIU data. No site specific uncontrollable sampling was conducted. Sludge Permit: We currently have a permit modification being reviewed by DWR (see attached letter). Calculations were made with an assumed value of 75 acres versus 79.1 acres.
