Tech Support has evaluated and recommends renewal of existing limits and chronic toxicity test. New analysis of metals and toxicant data has caused a revision of monitoring requirements. Monitoring for these metals: Cd, Cr, Cu, Ni, Pb, Zn and Cn, will be done in the Valdese Pretreatment Program's Long Term Monitoring Plan (LTMP). All new and expanding dischargers of oxygen consuming wastes that discharge to the Catawba River Chain of Lakes or are predicted to increase oxygen demanding waste loading to the lakes, (Lake James, Rhodhiss Lake, Lake Hickory, Lookout Shoals Lake, Lake Norman, Mountain Island Lake, and Lake Wylie) will be required to meet a minimum of advanced treatment limits. Typical NPDES permit conditions for advanced treatment facilities are 15 mg/1 BOD5 and 4 mg/1 NH3-N. These limits will help to protect water quality standards in the Catawba River chain of lakes and will allow for�(continued growth in the re on.

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 4.8 % (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 228.7 cfs Permitted Flow 7.5 MGD IWC 4.8 % Basin & Sub -basin CTB31 Receiving Stream Lake Rhodhiss County Burke QCL PIF Version 9191 VALDESE WWTP 1/5/95 LAKE RHODHISS JMN 030835 Facility requesting renewal of existing NPDES permit for 7.5 MGD plant. Valdese discharges into Lake Rhodhiss, approximately 2 miles downstream of the Morganton (8 MGD) discharge and approximately 1 mile below the Valdese water supply intake. The WTP is planning an expansion from 8 MGD to 12 MGD (per 1993 EA). Staff concluded that the increase in withdrawal would not effect downstream discharges or aquatic life because of the volume of water in Lake Rhodhiss. Current limits are 30/30, monitoring for NH3, DO, chlorine, Cd, Cn, Cr,Cu, Ni, Pb, Zn, Chlorides, Sulfates, and Phenols. No apparent problems with compliance, however have had exceedances of TSS limit in Feb., March, and August 1994. A chronic ceriodaphnia toxicity test of 4.8% (JAN APR JUL OCT) is also included in the permit. Facility has consistently passed tox test since Feb. 1992. The Instream Assessment Unit does not have a lake model and the Level B results are not reliable for this type of water body. However a Level B model that was run (1992) did predict a DO minimum of 3.5 mg/1 about 15 miles downstream of Valdese's discharge. USGS and other agencies are working on a model for the Catawba chain lakes and results should be available within the next permit. BACKGROUND: Original limits of BOD=18, NH3 = 8, TSS of 30 mg/1, fecal of 200, pH = 6-9, TP limit of 1.0 mg/1 (EPA required) were issued in 1978. In 1979, the Town requested a change in the limits to BOD=30, NH3 =5 mg/1. DEM concurred with this request since the UBOD would remain the same. In 1983, new Level B model of Valdese plant was done and limits of 30/30, fecal limit and pH limit were established. No longer had NH3 limit or TP limit.1989 WLA renewed existing limits but added monitoring requirements for NH3, Cd, Cn, Cr, Cu, Ni, Pb, Zn, chlorides, sulfates, and phenols. The chronic toxicity test of 4.8% was also given at that time. RECOMMENDATION: Renewal of all conventional limits: 30/30, fecal limit of 200, pH, effluent monitoring for NH3, chlorine, TP, TN. Toxicity test of 4.8% renewed also. Limit for phenols of 21 µg/i. TOX ANALYSIS - Limit for Phenols of 20.7 µg/1 Monitoring for most metals wool be deleted from NPDES permit and monitored under pretreatment .LTMP based on toxicity analysis. Also monitoring for chloride and sulfates not longer needed. 1/9/95 Meeting w/ Tom Poe of Pretreatment: Concurs with tox analysis, LIMP will be monitoring for Cd, Cr, Ni, Pb, Cn, Cu, and Zn. 0 TiceS /3 /9f, 3o/10- s z — ff 4414;5 - /s/`fe/s-- 7,5-s /, s ,q , a/4h.,7tr- ,, raw,/ 7MC44.
