MISCELLANEOUS INFORMATION & SPECIAL CONDITIONS Adequacy of Existing Treatment Has the facility demonstrated the ability to meet the proposed new limits with existing treatment facilities? Yes No If no, which parameters cannot be met? Would a "phasing in",of the new`limits be appropriate? Yes No If yes, please provide a schedule (and basis for that schedule) with the regional office recommendations: If no, why not? Special Instructions or Conditions Wasteload sent to EPA? (Major) (Y or N) (If yes, then attach schematic, toxics spreadsheet, copy of model, or, if not modeled, then old assumptions that were made, and description of how it fits into basinwide plan) Additional Information attached?

QCL PIF Version 9191 ' Ftcility Name Town of Benson WWTP Permit # NCO020389 Pipe # 001 CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY) The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in: 1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic Bioa Procedure - Revised *September 1989) or subsequent versions. The effluent concentration at which there may be no observable inhibition of reproduction or significant mortality is 90 % (defined as treatment two in the North Carolina procedure document). The permit holc shall perform quartermonitoring using this procedure to establish compliance with the permit conditio The first test will be performed after thirty days from the effective date of this permit during the month, Jan., Apr., Jul., and Oct. Effluent sampling for this testing shall be performed at the NPDES perm final effluent discharge below all treatment processes. All toxicity testing results required as part of this permit condition will be entered on the Effluent Dischar 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: Environmental Sciences Branch North Carolina Division of Environmental Management 4401 Reedy Creek Road Raleigh, N.C. 27607 Test data shall be complete and accurate and include all supporting chemical/physical measurements perfc in association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the efflt toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste strea Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly monitorir begin immediately until such time that a single test is passed. Upon passing, this monthly test requireme 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 Environmental Management indicate potential impacts to the receiving stream, this permit may be re-oper 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 wil constitute noncompliance with monitoring requirements. 7Q10 Permitted Flow IWC Basin & Sub -basin Receiving Stream County 0.0 cfs 1.5 MGD 100 % 03-04-04 Hannah Creek Johnston Recommended by: Faaell Keough Z4 4 3 Date QCL P/F Version 9191 4(ZaH3 !;V1 7-6 iq3 Facility Name : Town of Benson WWTP Permit Number / Engineer: NCO020389 Kepler Subasin / Recieving Stream: 03-04-04 Hannah Creek Request Number / Date : 7196 1 1 /2/92 Request Logged -In: Existing WLA File Checked: Staff Report: Topo-map checked: USGS Flows confirmed: PIRF: IWC Spreadsheet: Nutrient Sensitivity: Stream Classification: Instream Data: Comments x x AOIS , /n/ Z M X � COMPLl1 AK-E C1i+t(-- M&,,, (, 0193 History: C"LDAW—(c ,pClAp; rll '10- (31211.,, c OCT .)W4 Ape- JJ' c�xzaE,�t IIMRs RC.Po�T 1�j}q}�l�-ti 1416%4C5' MnnJTNLV NLMQC_q_ V/oluf" ca.ipp,n acc�/Ci 3z1. - A/111N Z TeTat �ul�d5 rr.a /� � 8ci n n � A I NOW mime.
