Martin, Governor William W. Cobey, Jr., Secretary August 24, 1990 Mr. Ron Huff Hobbs Upchurch & Associates P.O. Box 1737 Southern Pines, North Carolina 28388 Subject: Moore County Water Pollution Control Plant Wasteload Allocation Notes NPDES Permit No. NC0037508 Moore County Dear Mr. Huff, George I Everett, Ph.D. Director Attached you will find the wasteload allocation (WLA) notes for the Moore County discharge into Aberdeen Creek. The analysis was performed in December, 1986, for the NPDES Permit renewal. When the permit is renewed, there may be some changes in the effluent limitations and requirements according to new proce- dures, standards, and classification changes. I have also attached the Division of Environmental Management's (DEM) desktop modeling procedure. This document is intended to provide a general summary of the modeling assumptions used by the Technical Support Unit. Procedures can change or assumptions for this particular application may be changed by DEM to more accurately simulate the receiving stream's impact. Please let me know if there are any further questions regarding this analysis.

The North Carolina Ceriodaphnia chronic effluent bioassay proce- dure (North Carolina Chronic Bioassay Procedure - Revised *February 1987) or subsequent versions. The effluent concentration at which there may be no observable inhibi- tion of reproduction or significant mortality is !. % (defined as treatment two in the North Carolina procedure document). The permit holder shall perform gr�eV monitoring using this procedure to establish compliance with the hermit ondition. The first test will be performed within thirty days from issuance of this permit. Effluent sampling for this testing shall be performed at the NPDES permitted final effluent discharge below all treatment processes, including chlorination. There may be no dechlorination of the effluent sample prior to testing. 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 parameter code . Additionally, DEM Form AT-1 (original) is to be sent to the following address: Attention: Technical Services Branch North Carolina Division of Environmental Management P.O. Box 27687 Raleigh, N.C. 27611 Test data shall be complete and accurate and include all supporting chemi- cal/physical measurements performed in association with the toxicity tests, as well as all dose/response data. Total residual chlorine must be measured and reported if employed for disinfection of the waste stream. Should any test data from this monitoring requirement or tests per formed by the North Carolina Division of Environmental Management 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 docu- ment, such as minimum control organism survival and appropriate environmen- tal controls, shall constitute an invalid test and will require immediate retesting. Failure to submit suitable test results will constitute a fail- ure of permit condition. �Or 10 io= K - ?.'
