Total Residual Chlorine monitoring is required only if chlorine or chlorine derivative is added during the treatment process. The Division shall consider all effluent TRC values reported below 50 ug/1 to be in compliance with the permit. However, the Permittee shall continue to record and submit all values reported by a North Carolina certified laboratory (including field certified), even if these values fall below 50 ug/1. 3. After submitting 12 months of data and a minimum of 12 data points, the permittee may request the Division reevaluate themonitoring requirements. 4. See Special Condition A. (2.).

CHRONIC TOXICITY MONITORING (QRTRLY) The permittee shall conduct quarterly chronic toxicity tests using test procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, 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. 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: NC DENR / DWQ / 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 then 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. 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.

After careful review, the draft permits have been revised and copies are enclosed with this letter. Please review the drafts very carefully to ensure thorough understanding of the conditions and requirements they contain. After obtaining additional information regarding your treatment process and since the source water is groundwater, the monitoring requirements for another type of water treatment plant have been applied in accordance with the Division's permitting strategy for potable water treatment plants. The limits for Total Suspend Solids have been reduced for the Maxton WTP and Kenric Road WTP in accordance with Title 15A NCAC 02B .0224 as these facilities discharge into high quality waters of the state. Additionally, Zinc monitoring must remain in the permit for the Maxton WTP because zinc orthophosphate is used as a corrosion inhibitor at that facility. Submit any comments to me regarding these revised draft permits by September 11, 2009. Comments should be. sent to the address listed at the bottom of this page.
