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 q 9 % (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 issuance of this permit during the months of V MP( AOcr, Na . Effluent sampling for this testing shall be performed at the I4PDES` 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 P.O. Box 27687 Raleigh, N.C. 27611 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. 7 Q 10 cfs Permited FI w .O0T MGD Recommended by: 1WC% too Basin & Sub -basin (1)3- o'.I - 0 3.

Martin, Governor George T. Everett, Ph.D. William W. Cobey, Jr., Secretary June 1, 1990 Director Albert E. Finley Pope Industrial Park P.O. Box 18571 Raleigh, NC 27619 Subject: Chlorine Toxicity NPDES Permit No. NC0060526 Wake County Dear Mr. Finley: Chlorine, a widely used wastewater disinfectant for the treatment of coliform organisms, often remains instream in residual amounts that may prove to be toxic under critical low stream flow conditions. In the last decade, EPA assessed the potential adverse effects of chlorine to the aquatic environment and has taken steps to reduce the impacts through the development of federal criteria. In 1986, EPA recommended that all states have a chlorine standard by their next triennial review of water quality standards. In revising its water quality standards in 1989, North Carolina developed an action level for chlorine of 17 ug/1 (freshwater classes only). In addition, the fecal coliform limit was reduced from 1000 colonies/100 ml to 200 colonies/ 100 ml. Under a new DEM procedure, dechlorination and chlorine limits are now recommended for all new or expanding dischargers proposing the use of chlorine for effluent disinfection. The Division is reviewing chlorine levels from all existing dischargers as part of their NPDES permit renewal process. Our records indicate that chlorine from your facility's effluent discharge is considered toxic to the receiving stream under low flow.. conditions, i.e., the amount of chlorine discharged causes a violation of the instream action level for chlorine (17 ug/1) under 7Q10 conditions (the average flow for seven (7) consecutive days during a ten (10) year period). Action should be taken to reduce the effluent concentration of chlorine to an acceptable level. Based on your facility's instream waste concentration of 100%, an acceptable level of chlorine in your effluent is 17 ug/l. If this level is not feasible, you should consider dechlorination or alternate methods of disinfection for your facility to ensure that both chlorine and bacterial limits are met. In addition, if your facility plans to undertake any phase of construction, dechlorination or alternate disinfection should be included. However, please note that an authorization to construct must be obtained from this Division prior to any alteration to your treatment plant. Polludon Prevention Pays P.O.

Artinn FmnInvvr -2- The Division is currently reviewing its water quality regulations pertaining to chlorine. In the future, effluent limits and/or dechlorination may be required of existing facility's with chlorine problems. If the chlorine levels in your facility's effluent remain unchanged, a chlorine limit or a whole effluent toxicity testing requirement may be added to your permit limitations. Please feel free to call Tim Donnelly of the Division's Regional Office at (919) 733-2314, if you have any questions or comments regarding this issue.

The following commercial & light industrial businesses were discharging waste to the wastewater treatment plant at the time of the site inspection: Pope Industrial Park Page -4- 1. Raychem - Warehouse storage 2. Norman Killette Printing Co. - has the potential of discharging printing make up solution waste and was discharging waste from a silver recovery unit - may discharge waste w/approximately 15 mg/1 of Ag. 3. Boxes unlimited - box storage 4. Thomas & Howard Co. - Food Distributors. This facility has 2 five -gallon buckets of insecticide. 5. Young Moving and Storage Co.- furniture moving and storage. 6. Weatherking - Offices 7. Caskie Paper Co. - Paper Storage 8. Dept of Human Resources - furniture storage 9. Veterinary medical Supply - Storage of pharmaceuticals 10. Hefner Tire Co. - Wholesale tire sales 11. Winn Dixie Any of these businesses could at times discharge toxicants to the WWTP. Duke Finley, VP of Pope Industrial Park has ordered the Kilette Printing Co. to cease discharging of process wastewater to the WWTP. However, until an alternative waste disposal method is available and used by the Kilette Printing Company, it is recommended that a limit for Silver be placed in the permit. The Pope Industrial Park WWTP effluent has been tested for toxicity and the results indicated that the discharge may cause toxicity problems in the stream. Therefore, monitoring and a limit for chronic toxicity is recommended. The WWTP itself has been experiencing toxicity problems causing die -off of activated sludge and the need to reseed the plant quite frequently. Therefore it is recommended that tests for Priority Pollutants be required. It is recommended that the permit be reissued in accordance with the basin -wide permitting plan and wasteload that considers the industrial components.
