(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 concentration of 41 The permit holder shall perform at a minimum, quarterh monitoring using test procedures outlined in the "North Carolina Ceriorlaphnia 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 March, June, September, and December. 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: North Carolina Division of Water Quality Environmental Sciences Branch 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 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.

The facility treats domestic and industrial wastewater using preaeration, grit removal, primary clarification, first stage aeration, intermediate clarification, second stage aeration, final clarification, chlorination, anaerobic sludge digestion, sludge drying beds, and post aeration. The facility maintains one outfall 001, which discharges into Aberdeen Creek. Aberdeen Creek is a class C stream and according to the 1999 Lumber River Basinwide Water Quality Plan is meeting its designated uses. The Moore County Regional WWTP is located in subbasin 03-07-50. Aberdeen Creek discharges into Downing Creek. Downing Creek is one of 11 waters in the Lumber River Basin which has a fish consumption advisory because of mercury and appears on the state's 303(d) list. In order to obtain better information for the development of a mercury TMDL the Division has implemented mercury monitoring for several dischargers in the Lumber River Basin. Moore County monitors mercury as part of their Long Term Monitoring Plan (LTMP). As long as Moore County continues to monitor mercury as part of their LTMP the facility will not be required to monitor mercury as a condition for the permit. TOXICITY TESTING: Current Requirement: Chronic Toxicity (Ceriodaphnia) P/F at 41%. Recommended Requirement: Continue with current requirements. COMPLIANCE SUMMARY: 1999 — Per DMRs the facility had no compliance problems through October of 1999. 1998 - Per DMRs the facility had no compliance problems in 1998. 1997 - Per DMRs the facility had no compliance problems in 1997. 1996 - Per DMRs the facility had no compliance problems in 1996. INSTREAM MONITORING: The facility is currently required to monitor the following parameters as part of their NPDES permit: fecal coliform, conductivity, temperature, and dissolved oxygen. It is recommended that the facility continue to PDFS iZ;:11cw."l flare J monitor all of the parameters listed except conductivity. It is recommended that conductivity monitoring be removed from the permit. PROPOSED CHANGES: A condition requiring mercury monitoring if the facility ceases to monitor mercury as part of their Long Term Monitoring Plan. Cyanide Monitoring has been removed from the permit. Since the facility has not detected cyanide in their effluent according to the last fours years of DMR data there is no reasonable potential for cyanide to exceed the allowable concentration. Reviewing Chronic toxicity results the facility has had no violations over the past four years, this further substantiates the removal of cyanide as a condition for the permit.

Notes for Moore County Regional Wastewater Treatment Plant General Information The Moore County Regional WWTP is a permitted 6.67 MGD facility. The Moore County regional Wastewater Treatment plant is a grade IV facility utilizing the following units: preaeration, grit removal, primary clarification, first stage activated sludge, intermediate clarification, second stage aeration, final clarification, anaerobic sludge digestion, sludge drying beds, post aeration. The facility maintains one outfall (001) which discharges into Aberdeen Creek, which is a class C stream, located in the Lumber River Basin. The facility has an approved pretreatment program and manages 4 SIUs. The SIUs appear to be operating in compliance with the WWTPs LTMP. The average flow for the facility is 5.39 MGD. The industrial contribution is 0.371 MGD. Per the NPDES permit renewal application the following may be present in the effluent: Cl, F, Al, Be, Ba, Cd, Cr, Cu, Fe, Pb, Ni, Se, Ag, Zn, chlorinated organic, surfactants, pesticides, Bromodichloro. methane, chloroform, dibromochloro methane. Permit Writer: MJM Permit #: NC0037508 Permit Modification Information January 9,1995 — A permit modification was issued in accordance with the revised pretreatment rules. The modification was to the biolerplate language of Part III.A-B. Wasteload Allocation Information The 1994 Wasteload Allocation for the currently permitted flow of 6.7 MGD states that the receiving stream Aberdeen Creek has a s7Q 10 stream flow of 15.2 cfs. Additionally, the report concludes that the w7Q 10 is 28.7 and that the average stream flow is 47.2 cfs. The drainage area is 36.3 square miles. The WLA states that several POC are monitored through the facilities LTMP. Correspondence File Review Information Speculative limit request was made November 16, 1999. Speculative limits were issued January 12,1999, for flows of 10 and 15 MGD. There is a note in the permit file that states that the speculative limit request was rescinded. DMR Review 1999 — Per DMRs the facility has no compliance issued through October of 1999. 1998 - Per DMRs the facility has no compliance issued through October of 1998. 1997 - Per DMRs the facility has no compliance issued through October of 1997. 1996 - Per DMRs the facility has no compliance issued through October of 1996. Basinwide Plan Review Subbasin 03-07-50 is the uppermost basin in the headwaters of the Lumber River Basin. The 03-07-50 subbasin covers an area of 273 square miles, two square miles of which are water. Land cover in the subbasin is largely forest/wetland and agriculture, 80% and 18%, respectively. Naked Creek is designated as Outstanding Resource water and Drowning Creek has been designated as High Quality water. There is 184.4 mile of tributaries with 178.5 miles `Fully Supporting' their designated uses and the remaining 5.9 miles designated uses are `Fully Supporting but Threatened'. There are five permitted dischargers in the subbasin, with the largest being the Moore County Regional WWTP with a permitted discharge of 6.7 MGD. The only ambient sampling point downstream of the Moore County Regional WWTP's discharge is downstream of the confluence of Aberdeen Creek and Drowning Creek. This ambient station is one of two stations in the subbasin which gather fish tissue data. The other fish tissue ambient monitoring station is located in Horse Creek, which is upstream of the confluence of Aberdeen Creek and Drowning Creek. Fish tissue data gathered in Horse Creek indicates mercury levels above EPA criteria (0.6 ppm), while fish tissue data gathered at the confluence of Aberdeen and Drowning Creek indicate that mercury levels above both the EPA criteria and the FDA criteria (1.0 ppm). General Comments 12/14/99 — Submitted LTMP request form to Steve Amigone (Pretreatment Unit) requesting the facilities LTMP data. 12/17/99 — According to the October 29, 1999 memo from Tom Belnick, Moore County monitors mercury through their pretreatment program. As long as the facility continues to monitor mercury through the LTMP then mercury monitoring will not be required as a condition of the permit. 12/1�/99 — per conversation with Dave Goodrich though the IWC ammonia calculation limit' NH3-N at 2.17 mg/l. It is Division policy to not impose this limit if the facility has a chronic toxicity test and has been in compliance with the toxicity test. Therefore, it recommended that the facility maintain the 17 mg/1 limit in the renewed permit. Reasonable potential analysis — Mercury — the facility has not detected mercury in their effluent according to the last four years of DMR data. Therefore, no reasonable potential exist. Additionally, as long as the facility continues to monitor mercury as part of LTMP, the mercury monitoring is not required. Cyanide — The facility has not detected cyanide in their effluent according to the last four years of monitoring data. Therefore, no reasonable potential exist. Copper — The reasonable potential indicates that there is no reasonable potential for the facility to exceed the action level for this parameter. However, the facility has regularly detected copper in their effluent, therefore it is recommended that copper monitoring remain in the permit. Silver — Reasonable potential indicates that the facility's effluent does have a reasonable potential to cause the receiving stream to exceed the action level standard for silver. Since the facility has had no problems passing chronic toxicity test, it is recommended that the facility monitor for silver. Zinc — Reasonable potential analysis indicate that there is not a reasonable potential for the facility's effluent to cause the receiving stream to exceed the action level standard for Zinc. Since the facility has had several detections of zinc it is recommended that zinc monitoring remain as a condition for the permit.
