The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic Bioassay Procedure - Revised *February 1987) or subsequent versions. The effluent concentration at which there may be no observable inhibition of reproduction or significant mortality is 56 % (defined as treatment two in the North Carolina procedur document). The permit holder shall perfomr quarter(v monitoring using this procedure to establish compliance with the permit condition. The first test vi11 be performed after thirty days from issuance of this permit during the months of lib, /tie{ . Effluent sampling for this testing shall be performed at the �1PDES pertiitted 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 aJdress: 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 chemical/physical r asurements 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 ernoloyed 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 strea.n, this permit may be re -opened and modified to include alternate monitoring requirements or mils. NOTE: Failure to achieve test conditions as specified in the cited document, such as mnmimum control organism survival and appropriate environmental controls, shall constitute an ir.:-alid 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 J5 cfs Permited Flow e.

These limits are described below: Existing Permit Limits Prop. New Limits (Daily Avg.) (Daily Max.) (Daily Max.) Fluoride Nickel 5.0 mg/1 10.0 mg/1 1000 ug/1 2000 ug/1 2.4 mg/1 67 ug/1 In discussions with Mr. Don Bailey, P. E., Director of Engineering, we have been advised that Teledyne foresees difficulty complying with the proposed new limits and questions why there was such a significant change. In discussing this matter with Carla Sanderson, it appears that the principal reason for the change is that a much larger discharge flow (.288 MGD) has been used as compared to the flow used in the previous Waste Load Allocation (<.003 MGD). The discharge flow of .288 MGD was obtained from Teledyne's application documents but, it should be noted that this reflects maximum discharge flow and not average daily flow. Teledyne has provided the attached letter dated January 16, 1989 which provides an estimated average daily flow. Teledyne's treatment facility is two (2) large cooling ponds in series which receive contact and non -contact cooling water, water filter backwash and storm runoff. Teledyne reuses _a Dale Overcash Trevor Clements Page Two January 30, 1989 water from the ponds as makeup water for process uses. Process wastewaters are discharged into the municipal sewer system. The discharge from the lower cooling pond only occurs during wet weather periods when the amount of extraneous flow into the ponds exceeds the recycling needs of the plant thus creating an overflow. Obviously this discharge will not be occurring under 7Q10 conditions. It is obviously inappropriate to base effluent limitations for this facility on a scenario of a maximum daily discharge flow occurring during summer 7Q10 stream flow conditions. At the least, we believe it is more appropriate to evaluate the limits based on the reported average daily discharge flow as reported in the attached letter. The Mooresville Regional office suggests that this information be considered and that Technical Services reconsider the appropriateness of the proposed limitations. If you have any questions or if you need any additional information, please advise.

BOX 5030 MONROE, NORTH CAROLINA 28110-0531 (704) 289-4511 TWX (810) 649.1359 Please find below a list of Teledyne Allvac's average daily flow readings for the months April through December 1988 as we discussed on the telephone.

It is felt that this is a representative effluent flow from the lower cooling pond for developing N.P.D.E.S. effluent limits. In most cases, the only time there is an effluent flow to Richardson Creek is during periods of wet weather which results from storm water run-offs into the cooling ponds. Please notify me if you have any additional need for information concerning this matter. Thank you for the opportunity to express our concerns over the present proposed N.P.D.E.S. limits and your consideration in that regard. Sincerely, Don M. Bailey, P.E.

Facility and Address: Teledyne Allvac (Monroe Plant) Post Office Box 5030 Monroe, North Carolina 28110-0531 2. Date of Investigation: December 1, 1988 3. Report Prepared By: J. Thurman Horne, P. E. 4. Person Contacted and Telephone Number: Mr. Don M. Bailey, P. E.; 704/289-4511 5. Directions to Site: In Monroe, traveling east on Highway 74, turn left on Walkup Avenue, travel approximately 0.2 mile, turn right on Sutherland Avenue, travel approximately 0.2 mile, turn left on Ashcraft Avenue, travel approximately 0.4 mile. Teledyne Allvac is on the right (south) side of Ashcraft Avenue. 6. Discharge Point - Latitude: 34° 59' 05" Longitude: 80° 30' 30" Attach a USGS Map Extract and indicate treatment plant site and discharge point on map. USGS Quad No.: H 16 NE 7. Size (land available for expansion and upgrading): The existing site encompasses approximately 50 acres. There is adequate land available for future expansion and modifications. 8. Topography (relationship to flood plain included): The terrain is mildly rolling with slopes generally less than 10%. The existing site is well removed from any flood plains. 9. Location of Nearest Dwelling: None within 500 feet. 10. Receiving Stream or Affected Surface Waters: Richardson Creek a. Classification: C b. River Basin and Subbasin No.: 03-07-14 Page Two c. Describe receiving stream features and pertinent downstream uses: The receiving stream is small and shallow. The point of discharge is approximately 0.8 mile downstream from a dam impounding Lake Lee. The only known uses of the stream for a reasonable distance below the discharge is for secondary recreation and agriculture. PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS 1. Type of wastewater: 0% Domestic 100% Industrial a. Volume of Wastewater: .288 MGD b. Types and quantities of industrial wastewater: Industrial wastewater discharges flow into a cooling pond (7 million gallon capacity). This pond also receives storm runoff. The majority of the water from the pond is recycled. Therefore, the volume discharged to surface waters is only a fraction of the total wastewater produced from the various industrial processes. Included with the permit application is a flow diagram showing the various volumes and sources of wastewater which are tributary to the pond. Based on the this information, it is estimated that the wastewater discharged to surface waters is comprised of the following percentages of industrial wastewaters: 1. Non -contact cooling water - 59% 2. Contact cooling water - 32% 3. Cooling tower water - 7% 4. Water filter backwash - 2% Note: The water filter backwash is generated from the filtration of water extracted from the ponds that is being reused in the plant processes. c. Prevalent toxic constituents in wastewater: The application contains sampling results which indicate the presence of Fluoride, Oil & Grease, Boron, Copper, Nickel and Zinc. The application also indicates that the following chemicals are added to the cooling waters: 1) Potassium Permanganate, 2) Calcium Hypoclorite and 3) a corrosion inhibitor - C395 manufactured by Industrial Maintenance Corporation. See Attachment "a" for a summary of sampling results. d. Pretreatment Program (POTWs only): N/A 2. Production Rates (industrial discharges only) in Pounds: a. Highest month in the last 12 months: Page Three Nickel -Cobalt Forming - 600,000; Titanium Forming - 300,000 b. Highest year in last 5 years Nickel -Cobalt Forming - 7,200,000; Titanium Forming - 3,600,000 Note: Production rates are based on information provided during site investigation. These are the quantities of metal produced which generate contact cooling water. 3. Description of Industrial Process (for industries only) and Applicable CFR Part and Subpart: Nonferrous Metals Category: 1) Nickel and Cobalt Subcategory; 2) Titanium Subcategory 4. Type of Treatment (specify whether proposed or existing): Wastewater enters either of two (2) existing cooling ponds (in series). Water from the ponds is recycled. Overflow from the lower pond passes through an oil skimmer prior to discharge. 5. Sludge Handling and Disposal Scheme: Due to the nature of the wastewaters and the volume of the cooling ponds, sludge has not accumulated in sufficient quantities to require removal nor is this anticipated to happen. 6. Treatment Plant Classification: Class I 7. SIC Code(s): 3356 Wastewater Code(s): 14 15 17 21 PART III - OTHER PERTINENT INFORMATION 1. Is this facility being constructed with Construction Grants Funds (municipals only)? N/A 2. Special monitoring requests: Continued monitoring for Nickel, Fluoride, Copper and Zinc. 3. Additional effluent limits requests: Nickel and Fluoride 4. Other: None Page Four PART IV - EVALUATION AND RECOMMENDATIONS It is recommended that the Permit be renewed as requested.

Since ammonia is part of the in- dustrial waste for this facility, a Level-B analysis was per- formed. From this analysis it was determined that the facility would receive a stricter limit for ammonia than the BPT given per federal guidelines. Thurman Horne of the Mooresville Regional Office was contacted to inform him of the more stringent ammonia limit for this facility. I am awaiting information from Thurman before processing the WLA. cc: Thurman Horne
