Box 1089 Fayetteville, North Carolina 28302-1089 Subject: NPDES Draft Permit Permit No. NC0050105 Rockfish Creek WRF Cumberland County Facility Class IV Dear Mr. Noland: Enclosed with this letter is a copy of the draft permit for your facility. Please review the draft very carefully to ensure thorough understanding of the conditions and requirements it contains. The draft permit contains following significant changes from your current permit: • The special condition A. (10.) was updated. • A new footnote wording for the total residual chlorine limit has been added. • The effluent page for 16 MGD flow was removed. The quarterly mercury monitoring was added' based on the results of the Reasonable Potential Analysis. • The quarterly mercury monitoring for zinc, copper, and silver was removed based on the results of the Reasonable Potential Analysis. - • A mercury TMDL re -opener was added to address upcoming implementation of the TMDL. The Division is unable to grant your request to reduce the monitoring frequency for CBOD, TSS, NH3-N, Fecal Coliform, and Whole Effluent Toxicity. The monitoring frequencies for these parameters are established by 15A NCAC 2B .0500.. Please submit any comments to me no later than thirty days following the public notice date. Comments should be sent to the address listed at the bottom of this page. If no adverse comments are received from 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Location: 512 N.

CHRONIC TOXICITY PERMIT LIMIT (QRTRLY)- for 21 MGD The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent concentration of 4.6%. The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The tests will be performed during the 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 statistical 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 in which tests were performed, using the parameter code TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the following address: Attention: Environmental Sciences Section North Carolina Division of Water Quality 1621 Mail Service Center Raleigh, North Carolina 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, 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 permittee 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 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. 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. (5.) CHRONIC TOXICITY PERMIT LIMIT (QRTRLY)- for 24 MGD The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent concentration of 5%.

A. (6.) CHRONIC TOXICITY PERMIT LIMIT (QRTRLY)- for 28 MGD The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent concentration of 6%. The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
