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 34.0% (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 March, June, September and December. 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.

Color monitoring should consist of ADMI monitoring as specified below. All samples taken should have complete descriptive recordings of the color in the sample container including hue (distinctive characteristics and tint), clarity (clearness of the color sample) and luminance (brightness or glowing quality) of the sample as it looks in the collection container. Descriptions of stream color should also be recorded when color samples are collected. Color samples should be analyzed as follows: a) at natural pH b) free from turbidity (True Color); and c) Samples shall be analyzed in accordance with the provisions of Method 2120 E.4. as described in the 18th Edition of Standard Methods for the Examination of Water and Wastewater. Using a narrow -band scanning spectrophotometer to produce a COMPLETE spectral curve of the visible spectrum (350-75- nm), calculate and report results in ADMI values for true color values at the sample's ambient pH value. All color data including visual observations should be submitted with the monthly DMRs. Color Monitoring Location and Frequencies: Color Monitoring shall take place instream above the effluent outfall, downstream below the effluent outfall and in the effluent. Frequency shall be 3 consecutive days (preferably Tuesday, Wednesday and Thursday) once per month. Cherryville WWTP JMN Indian Creek Class C 11/1/94 030835 Facility requesting renewal of existing NPDES permit for discharge into Indian Creek. Background Notes: Cherryville outfall was previously located in Lick Fork with limits of 30/13/6 but EPA review found these limits tOe unacceptable because it caused DO = 0 mg/l in Indian Creek (downstream receiving/stream of Lick Fork). EPA recommended that limits of 5/2/6 be assigned for the Cherryville plant discharging into Lick Fork, in order to keep DO above 5 mg/1 in Indian Creek. Correspondence in WLA indicates that facility requested to be relocated the larger Indian Creek. New Level B models were run and limits of 30/17/5 were developed for discharge into Indian Creek. Limits for toxics (Cd, Ni, Pb, Cn, and Cr) were developed as well as inclusion of a quarterly whole effluent toxicity test @ 34% . Monitoring for Cu and Zn, as well as Phenols (because of effluent samples taken by MRO). Review of compliance data has shown 3 violations for flow and 1 violation for TSS. No violations for toxics that are sampled, in fact, all parameters are consistently below detection. Only one value each for Cr, Ni, and Pb above detection in the past 12 months. Talked with Joe Pearce of Pretreatment concerning POCs and future monitoring/limits. Per Joe, Cherryville will no longer have a long term monitoring plan. The facility will receive the new Modified Pretreatment Program - for POTWs with a design flow of > 2 MGD and having few than 4 SIUs. Under the new program, once every five years the facility will have to monitor the influent and effluent for four consecutive days. Cherryville has two SIUs, one textile @ 1 MGD and the other industry at 75,000 GPD. Recommendation: 1) Per SOP, upon renewal of NPDES permit, Quarterly monitoring for Cadmium, Nickel, Lead, Cyanide,Chromium, Copper, and Zinc. *These monitoring requirements added in order to have enough data values to evaluate toxicity analyses at next permit renewal, since modified pretreatment program will not provide enough data. 2) Deletion of phenols monitoring because Indian Creek is not classified as WS stream. 3) Renewal of conventional limits and modification of fecal limit from 1000 to 200/100 ml.

Other Special Items: PART IV - EVALUATION AND RECOMMENDATIONS The City of Cherryville is applying for renewal of its permit for the operation of wastewater treatment facilities. The wastewater treatment facilities were in good operational condition at the time of inspection. Effluent quality appeared excellent and no detrimental effect was observed on the receiving stream. Self -monitoring data was reviewed for the period December, 1992, through November, 1993. Three Notices Of Violation (NOV) were issued for exceeding the monthly flow limits of 2.0 MGD. Moreover, the facility has exceeded the daily flow 28 times between January and April 1993. According to Mr. Shull, Plant Supervisor, surface water is entering the plant through broken pipes in the sewer system, and the City has initiated the repairs. Pending receipt and approval of a Waste load Allocation, it is recommended that the permit be renewed.
