Box 199 Catawba, North Carolina 28609-0199 Subject: NPDES Permit Modification CommScope Permit No. NC0034754 Catawba County Dear Mr. Waddell: The Division of Water Quality received your request for a permit modification on July 25, 2003. We apologize for the delay in responding to your request. In summary, your request specified that CommScope be allowed to discharge a portion of the contact cooling water into the existing 0.02 MGD treatment system. This request has been granted and is reflected in the change to Part A.(1.) of the permit, which is attached to this letter. The process water in Part A.(1.) has been specified as contact cooling water. CommScope should exercise caution in "bleeding -in" the contact cooling water to the existing treatment system. One pilot study may not provide enough information to ensure proper treatment of the wastestream (the Division of Water Quality would have preferred two more tests). However, based on your conversations with water quality staff, you are aware of these potential issues and will take corrective action as necessary. The revised page should be inserted into your permit. The old page may then be discarded. Ali other terms and conditions contained in the original permit remain unchanged and in full effect. This permit modification is issued under the requirements of North Carolina General Statutes 143-215.1 and the Memorandum of Agreement between North Carolina and the U. S. Environmental Protection Agency. If any parts, measurement frequencies or sampling requirements contained in this permit modification are unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt of this letter. This request must be a written petition conforming to Chapter 150B of the North Carolina General Statutes, filed with the Office of Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-6714). Unless such demand is made, this decision shall be final and binding. If you have any questions regarding the NPDES permit, please contact Susan Wilson at (919) 733 - 5083, extension 510.

I thought I had replied to you? Guess not! Anyway, I have no problem with you clarifying this with a permit modification. The way I read the permit it seems that they have had the authority to do this as well, but if they want to modify the permit so be it. Carry on.

Do you have any issues with this. It looks OK with me. Thanks.

They'd like to 'bleed -in' a certain amount of process wastewater into the domestic system (outfall 001), while still retaining outfalls 002 - 004. Looks like to me they've always had the ability to do this (via the description and fact sheet for 001). I spoke to him about this but it didn't seem like he thought that was the case. Anyway - I have no problem with it and I'm going to clarify it for him with the mod. What are your thoughts on this? I believe I sent the mod request down to you (at least I have a note to that effect).

This letter is intended to supply you with additional information as per your request. The following information is included in this packet: 1) Short Form C. Per our conversation on 7/23/03, the Short Form C was determined not to be applicable and thus is no longer part of the request for information. 2) Major Modification Fee: Check for $215.00 3) Chronic Toxicity Test Results from the treatability Study performed in February 2003 by Water Tech Labs Inc. 4) Estimated Flow information. The max flow associated with each sand filter bleed off is approx. 500 gallons / day per unit. We will have a total of 7 units that will be installed with the potential for 2 additional units (based on business conditions). Assuming 9 filters, this equates to a MAX flow of 4,500 gallons of contact cooling water that would be transferred to the WWTP for treatment. This MAX flow assumes that every pit would discharge the max C:\Documaas end Settings\wadde111My DocumentsEHS FIUNO SYSTEM \02-Calawbal3-&rvironmedal- Walee3.2 Wastewater Issues\WW7P Request for Modification Rev. 1(Juty 2003).doc 1 of 2 amount in 1 day, which is not feasible. The average flows are as follows. To help minimize potential impact on the WWTP the sand filters will be programmed to discharge at different times during the week. Each day of the week their will be 2 sand filters that will discharge / day which will equate to a flow of -1,000 gallons / day. (NOTE: It is believed that the 500 gallons / day is the maximum amount that these units would discharge and that after the system is up and running the actual discharge / day will be much less.) After receiving field data on the effectiveness of these units, adjustments may be needed to allow for more than 2 filters to discharge/ day but not to exceed the 1,000 gallons / day estimate. 5) Offsite costs. Average off -site costs for cleaning of contact cooling water pits and disposal of the contact cooling water is approximately $50,000 / year. 6) 3-Copies of the request packet. I would like to reiterate that we are not asking for an increase of discharge from the WWTP that is currently permitted for a discharge of 0.02 MGD. Additional equalization storage is still under review to allow for fluctuations in manufacturing as well as the ability to isolate incoming waste in the event of a process upset. Outfall # 2, 3 & 4 will not change. This modification will only directly affect outfall #1 If you should have any questions concerning information contained in the report, please feel free to contact me @ 828-241-63 5 6.

The treatment system is a 0.02 MGD conventional treatment system with filtration and chemical pH adjustment, as well as chlorination/dechlorination. The current permit allows some process wastewater, however - I believe the permittee was unsure if industrial process wastewater was allowed from this outfall and wanted to request a review. Outfall 001 is not used for process water at all currently. Outfalls 002, 003, 004 are not used for process wastewater either. The current method for disposal of the contact cooling water is recycle and pump/haul. This method is costly, so CommScope is seeking an additional alternative. The volume of wastewater the permittee wishes to "bleed -in" is approximately 4500 gpd. There are currently 850 employees on -site, with no expected employee growth in the near future. Even with 850 employees, the highest monthly average flow has been 0.008 MGD. With this average flow, the treatment plant should be able to accommodate the increased flow of 4500 gpd ( still under the capacity of 0.02 MGD). The permittee performed one pilot test for the proposed addition of the industrial wastewater. The toxicity test passed at the required 34%. Other chemical tests were conducted which were found to be below permitted levels. Although DWQ would have preferred two more pilot tests - DWQ will not object to the request. Based on conversations with Scott Waddell of CommScope - the permittee wishes to retain the permit requirements for Outfalls 002, 003, and 004. These outfalls were originally developed for the contact cooling water, but have not been used for that in many years. Should a process upset occur - they would like to retain these outfalls. The limits given for Outfall 001 will have to include the limits given for the categorical industry discharge (contact cooling water), as guided by 40 CFR 463. 1 CommScope NC0034754 Major Modification 1/30/03 Notes to file: NOTES FOR APPLICATION OF GUIDELINES: In addition to the existing limits for domestic wastewater, the limits for Outfall 001 will have to be modified to include the limits for contact cooling water. 40 CFR 463 PLASTICS MOLDING AND FORMING POINT SOURCE CATEGORY (STARTING AT 463.12 & 423.13), SUBPART A - CONTACT COOLING AND HEATING WATER SUBCATEGORY The basic permitting for Outfall 001 will have to be modified to include this subcategory. 463.12 Parameter Daily max, mg/1 BOD5 26 Oil & Grease 29 TSS 19 pH 6 - 9 S.U. A load level will be calculated for each contribution (contact cooling water and domestic wastewater) and then converted to a concentration based limit (daily max) for the total flow. BOD5 (daily max) For domestic ww, the existing daily maximum level is 24 mg/1 (summer) and 45 mg/1 (winter). The total flow for the domestic ww can be no greater than: 0.02 MGD (PF) - 0.0045 MGD (the maximum stated input of the contact cooling water) = 0.0155 MGD (total max domestic flow). The domestic load will be: 0.0155 * 8.34 *24 = 3.1025 #/day (summer) 0.0155 * 8.34 * 45 = 5.8172 #/day (winter) The contact cooling water load will be: 0.0045 * 8.34 * 26 = 0.9758 #/day 2 CommScope NC0034754 Major Modification 1/30/03 Total load for BOD5: Summer: 3.1025 + 0.9758 = 4.0783 #/day, which converts to 4.0783 / (0.02 * 8.34) = 24.5 mg/1 Winter: 6.793 #/day, 40.7 mg/1 Because the summer limit by this method is higher than the existing water quality based summer limit - the existing limit will remain in the permit (24 mg/1). Total load for TSS: 0.0155 * 8.34 * 45 = 5.8172 #/day (domestic) 0.0045 * 8.34 * 19 = 0.7131 #/day (contact cooling water) 6.5303 #/day / (0.02 * 8.34) = 39.2 mg/1 This concentration value will be given in the permit. Oil & Grease limit will be given as per the federal guidelines (29 mg/1 daily max) . The permittee's current effluent values are well under these levels. �ylr� T P2 5 \Rt-t. `h/°( —ii <p3-) t2.
