Oo Facility Name D - • CHRONIC TOXICITY TESTING REQUIREMENT (QRTRLY) The effluent discharge shall at no time exhibit chronic toxicity in any two consecutive toxicity tests, using test procedures outlined in: . 1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic Bioassay Procedure - Revised `February 1987) or subsequent versions. The effluent concentration at which there may be no observable inhibition of reproduction or significant mortality is % (defined as treatment two in the North Carolina procedure document). The permit holder shall perform quarterl monitoring using this procedure to establish compliance with the permit condition. The first est will be erformed after thirty dm-s from issuance of this permit duringthe months of -40 v Effluent sampling for this testing shall be performed at the NPD S permitted final effluent discharge below all treatment: processes. All toxicityI sung results required as art of this permit condition will be entered on the Effluent g q P Discharge Monitoring Form (MR-1) for the month in which it was performed, using th% parameter code TGP3B. 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 chemical/physical measurements performed in association with the toxicity tests, as well as all dose/response data. Totes residual chlorine of the effluent toxicity sample must be m6asured and reported if chlorine is employed for disinfection of the waste stream. Should any single quarterly monitoring indicate a failure to meet specified limits, then :: onthly monitoring will begin immediately until such time that a single test is passed. Upon passing, 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 Environmental Management indicate potential impacts to the receiving stream, this permit maybe 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 and appropriate environmental controls, shall constitute an invalid test and will require immediate retesting; (within 30 days of initial monitoring event). Failure to submit suitable test results will constitute noncompliance with monitoring requirements. 7Q10 _I•'a cfs Permited Flow-. 0 _ MGD Recommended by: IWC% 39, 9 Basin & Sub -basin f)30'766/�A " Receiving Stream. rd Crenk County Date **Chronic Toxicity (Ceriodaphnia) P/F ate% % v; Oct, See Part, Condition .T .
