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 if % (defined as treatment two in the North Carolina procedure document). The permit holder shall perform quarterly monitoring using this procedure to establish compliance with the permit condition. The first test will be performed after thirty days from issuance of this permit during the months of MAK .7"14 SEP DEe . 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, 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, ad 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 any single quarterly monitoring indicate a failure to meet specified limits, then monthly 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 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 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 77 cfs Permited Flow 6.0 IWC% it MGD Recommended by: Basin & Sub -basin C79Jf Receiving Stream Sogrotek cAtm.id4 2&t County Linlc.d4 **Chronic Toxicity (Ceriodaphnia) P/F at /1 %, MAR7uAlJ6P het , See Part 3 , Condition x. DIVISION OF ENVIRONMENTAL MANAGEMENT January 3, 1989 MEMORANDUM TO: Rex Gleason THROUGH: David Vogt -v Trevor Clements FROM: Jackie Nowel4 SUBJECT: Recommendation for Addition of Phenols Limit to City of Lincolnton's NPDES Permit NPDES Permit No. NC0025496 Lincoln County The Technical Support Unit has recently completed the waste - load allocation for renewal of the NPDES Permit for the City of Lincolnton. Upon review of file data, we found that a water quality'sample of Lincolnton's effluent taken in September, 1988 recorded a data value for phenols of 18 ug/1. Although this was the only datum for phenols, it does show the presence of this constituent in Lincolnton's wastewater. The pretreatment head - works analysis that accompanied the wasteload allocation did not have phenols included in domestic or industrial loadings. How- ever, based on the water quality sample and the fact that the Lincolnton WWTP discharges into WSIII waters, we are recommending the inclusion of a phenols limit of 9.3 ug/1 in the renewed Lin- colnton permit.
