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- rift tion of reproduction or significant mortality is 7j % (defined as treatment two in the North Carolina procedure document). The permit holder shall perform monitoring using this procedure to establish compliance with th ermi 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 the appropriate 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. 7Q10 ©. of cfs Permited Flow J&6 MGD Basin & Sub -basin 03 oK O 2 Receiving Stream Lt.j,.W Recommended By , ZoMrAL V C1.'S rv►co� (k.

This model was used since no data are available to support the use of a calibrated model. The empirical estimates of model parameters are presented in this package. Seasonal effluent limits were developed for Clayton based on winter/summer design conditions. There are no other known point source dischargers to Little Creek. The creek is classified as "C" waters for noncontact recreational uses and attainment of biological health. A relatively uniform distribution of forested, agricultural, and urban land uses is continued within the watershed. Schematic Clayton Swift Creek I. U.S.G.S. flow estimates are given on schematic Yield at 7Q10 flow = (0.6 cfs - 0.2 cfs) / 2.7 miles = 0.15 cfs / mi Yield at Winter 7Q10 = 0.6 / 2.7 = .22 cfs/mi II.

Therefore, Summer D.O. = 746 mg/l Winter D.O. = 9.2 mg/l Background BODult was assumed to equal 2 mg/l. Monitoring data indicate that this assumption may not be appropriate. The results of the model (attached) indicated an ultimate BOD allocation of 45 mg/l in the summer. By Division policy, the winter allocation can not be more than 2 times the summer allocation. Using the equation UBOD = BOD5 + 4 • NH3N * the summer and winter allocations are: Summer Winter BOD5 17 mg/l 30 mg/1 NH3N 7 mg/l 15 mg/1 D.O. 6 mg/1 6 mg/l This breakdown is different than that used by EPA.

Should there be a further review of the propos-ed AST requirement? Yes to Additional Explanation of #11-D. Monthly average upstream values for the past year are all well above the stream standard of 5 mg/P. Self -monitoring data shows that the lowest monthly average for the past year is 6.10 mg/P. The highest monthly average BOD5 value is 9.8 mg/l. Therefore, there appears to be some de- gradation from nonpoint sources. The minimum D.O. at the downstream station was 4.48 mg/l. Seasonal Effluent limits North Carolina has adopted a regulation allowing seasonal effluent limits (attached). This regulation became effective on August 12, 1979. The winter model analysis procedure is detailed in the model notes for winter effluent limits. 2-5 Regulation 15 NCAC 2U .0404; LFFLULNT LIMITATIONS IN WATER QUALITY LIMITLD SUMENTS; has been amended and reads as follows: (a) Effluent limitations more stringent than minimum treatment requirements shall be developed by the staff and approved by the director for all existing or proposed dischargers to water quality limited segments of the surface waters of the state. The basis of these water quality effluent limitations shall be maintenance of water quality standards. (b) The staff Shall also provide on a case -by -case basis for seasonal variation in the discharge of oxygen-consuninq wastes. In order to be considered eligible for sea=l eftluenl limitations, a request must be submitted to the director along with a rationale as to the need for such limitations. Permit reissuance or modification during the remaining time of an existing periK will be considered on the basis of demonstrated need. In no cage ,hall tnis variation cause or be expected to cause a receiving wKer body to violate applicable water duality Aandards. (c) For the purpose of determining sca,ondl etfluent limitations, the year shall consiNt of a summer and a winter discharge period. The summer period will begin April 1 and extend thruugh Uctober 31. The winter period shall be that portion of the year from November 1 to March dl. the summer oxygen -consuming wasteload allocation shall be developed using the flow criteria specified in 15 NCAC 21i .0206. The winter oxygen -consuming wasteload allocation shall in no case be less stringent than two times the summer oxygen -consuming waste load limitations nor shall it be less restrictive than minimum treatment requirements. HISTORY NOTE Statutory Authority G.S. 143-215.1; Eff. February 1, 1976; Amended Eff. Aunust 12., 143-215.3(a)(1); 143-215; 1979. Secondary vs. Advanced Secondary Treatment At design stream conditions, the model predicted that the D.O. would sag below the standard of 5.0 mg/l to a minimum of 0 mg/1 if a BODult of 110 mg/l (secondary limits) were discharged. Thus, a secondary allocation would result in a violation of stream standards during certain periods. i i i, �I u rAr zhn v 2i ups 7Pr c&f zrzr� z�� Well 2b�vZ- li 1 'E mon4in paS� y 1 'o m jP .
