Facility Name BREVARD WWTP Permit # NC0060534 _ 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 _2.4_% (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 _JAN APR JUL OCT .. 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 161 cfs Permitted Flow 2.5 MGD IWC 2.4 % Basin & Sub -basin CTB35 Receiving Stream French Broad River County Transylvania / /D /28/9 Recommended by: a 3 5 QCL PIF Version 9/91 BREVARD WWTP JMN FRENCH BROAD RIVER C 8274 040301 The facility is requesting renewal of existing NPDES permit for 2.5 MGD plant. There are no expansion or modification requests with the renewal. The last correspondence from the facility was a 1992 request for an exemption from the requirement for 85% removal of BOD5. No info in WLA about whether the exemption was allowed by the Division. However the existing permit says the monthly average effluent BOD5 and TSS concentrations shall not exceed 15% of the respective influent value (85% removal). The wasteflow is 100% domestic with no significant industrial users contributing waste to the Brevard plant. Compliance data shows that the facility is well operated, all limits are being met with the exception of pH, which has violated limits of 6-9 SU for the past six months.

Brevard must meet all three requirements of 40 CFR 133.103 (d) in order to receive an exemption. Brevard must show that: 1.) permit limits for BOD5 are consistently met but percent removal is not met due to less concentrated influent, 2.) significantly more stringent limitations than those required by the permit, i.e., less than 30 mg/I, would be met if 85% removal were achieved, and 3.) the less concentrated influent wastewater is not the result of I&I. Brevard should submit a summary of influent and effluent data for our review and show that the low influent values are not the result of excess I&I. The City of Wilminton's Northside plant requested the same variance last year. We did not delete the 85% removal requirement but reduced it to 79% based on a review of 5 years of influent and effluent data. If the above requirements are met, Technical Support has no objection to a reduction in the 85% removal requirement for the Northside WWTP. If you have any questions regarding my comments, please let me know. cc: Asheville Regional Office Central Files DIVISION OF ENVIRONMENTAL MANAGEMENT Permits and Engineering/ NPDES Unit July 29,1992 Memorandum TO: Technical Support Branch FROM: Randy Kepler ;, SUBJECT: City of Brevard Brevard WWTP/ NC0060534 Transylvania County Attached is a letter from the city of Brevard.

ATTORNEY 20 May 1992 Mr. George T. Everett, Director State of North Carolina Division of Environmental Management Post Office Box 27687 Raliegh, North Carolina 27611-7687 RE: City of Brevard, North Carolina NPDES Permit NC 00605534 Dear Mr. Everett: The purpose of this letter is to request an exemption for the City of Brevard Wastewater Treatment Facility 85% removal effluent limitations. In May of 1986 the construction of this facility was completed and initial start up and operation began. The facility has produce quality effluent and has been in compliance with the NPDES permit since that time. However, with the renewal of the NPDES permit in 1991, and the implementation of the 85% removal regulation, this treatment facility has been in noncompliance with 85% removal during several reporting periods. However, this facility has not exceeded 30 mg\1 of TSS or BOD in the effluent as a monthly average. Extremely low influent BOD loading is the cause of this inability to achieve 85% removal. The facility was designed to treat an influent BODS of 200 mg/1, which is standard engineering ATIVETZ MAY 2, DIV. OF ENVIRONMENTAL MGMNT. DIRECT OFFICE - MAY y 1993 KATHERINE E. ANDERSON MAYOR CITY COUNCIL S. MACFIE MORROW MAYOR PRO TEM N BELL GARET GARREN BRY HARRIS NNY PETERSON 151 W. MAIN ST. BREVARD, NORTH CAROLINA 28712 704 884-4123 1 practice. Influent BOD5 for the Brevard facility have consistently been from 50 to 100 mg/1 since operations began in May of 1986. Effluent BOD5 for the last 5 years have averaged 15 to 18 mg/1. An exemption from the 85% removal of BOD will not contribute to the degradation of the French Broad River, as effluent TSS and BOD have been and are expected to be well below the 30 mg\l permit limits. Thank you for your time and consideration in this matter. If you have any further questions please feel free to call me at 704 883-8468. Sincerely, Donald G.
