Model results indicate that existing limits for conventional pollutants can be renewed. Facility requested that limits for cadmium, chromium, and silver be deleted from the NPDES permit, however since these are recommended per federal effluent guidelines they should remain. Per Lake Wylie Management Plan, CR Industries will be required to meet state -of -art nutrient removal. The facility will be allowed a five year time frame with which to come into compliance with TP limit of 0.5 mg/l and summer/winter TN limits of 4 and 8 mg/I, respectively. *Used revised 7Q10 flow for toxicity limit & IWC, however renewed existing metals limits until additional review of interaction of toxic substances.

Special Instructions or Conditions Facility Name CR Industries Permit # NC0004260 _ 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 Bioassay Procedure - Revised *September 1989) or subsequent versions. The effluent concentration at which there may be no observable inhibition of reproduction or significant mortality is _3.3_% (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 the effective date of this permit during the months of _FEB MAY AUG NOV . 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: 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 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 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 6.7 cfs Permitted Flow 0.148 _ MGD IWC 3.3 % Basin & Sub -basin CTB37 Receiving Stream Crowders Creek County Gaston QCL PIF Version 9/91 TOXICANT ANALYSIS Facility Name CR INDUSTRIES , NPDES # NC0004260 Qw (MGM 0.148 7010s (cfs) „_„_..._.._.._.._.._.._.._.._.._.._3 7. 0� IWC (%) Reeving Stream _i Crowders Creek ; Stream Class C FINAL RESULTS Phenols Max.

I further certify that this facil- ity is implementing the toxic organic management plan submitted to the permitting [or control] authority." For direct dischargers, this statement is to be included as a "comment" on the Discharge Monitoring Report re- quired by 40 CFR 122.44(1), formerly 1 Environmental Protection Agency 40 CFR 122.62(1). For indirect dis- chargers, the statement is to be includ- ed as a comment to the periodic re- ports required by 40 CFR 403.12(e). If monitoring is necessary to measure compliance with the TI'O standard, the industrial discharger need analyse for only those_pollutants which would reasonably be expected to be present. �(b)-In requesting_the certification_al �ternative, a discharger shall submit a solvent management plan that speci- fies to the satisfaction of the permit- . ting authority (or, in the case of indi- rect dischargers, the control author- ity) the toxic organic compounds used; the method of disposal used instead of dumping, such as reclamation, con- tract hauling, or incineration; and pro- cedures for ensuring that toxic organ- ics do not routinely spill or leak into the wastewater. For direct dischargers, ' the permitting authority shall incor- porate the plan as a provision of the permit. (c) Self -monitoring for cyanide must be conducted after cyanide treatment and before dilution with other streams. Alternatively, samples may be taken of the final effluent, if the plant limitations are adjusted based on the dilution ratio of the cyanide waste stream flow to the effluent flow.
