An examination of the Cape Fear basin plan and the NPDES permit schedule has revealed that the existing expiration dates in Cape Fear NPDES permits do not coincide with the revised permit expiration dates for the basin. This discrepancy could create unnecessary delays in the processing of over 200 permit renewals. Accordingly, the Division is changing the permit expiration dates for NPDES permits in the Cape Fear river basin. This permit modification changes the expiration date of the subject permit in subbasin 30616 to October 31, 2001. Please find enclosed the revised permit cover page. Insert the new cover page into your permit and discard the old page. All 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. In accordance with the modification of the permit expiration date, the new due date for your renewal application is May 4, 2001. Renewal application forms will be sent to you approximately 6-8 weeks in advance of the new due date or you may download the forms from the NPDES web site at http://h2o.enr.state.nc.us/NPDES/documents.html. You will need to download Standard Form C. If you have already submitted a permit renewal form, there is no need to submit any other forms to the Division; the application will be processed during the renewal period for your subbasin. If any part of 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 concerning this permit modification, please contact Natalie Sierra at (919) 733-5083, extension 551.

Our thought is to go ahead and make the pump change now. It sounds like a process change, so no ATC would be needed. We can take another look at the additional fluorocarbons during permit renewal. It doesn't look like they would be limited by either Federal Guidelines or NC water quality standards. At most we might consider monitoring. Are there any analytical tests for effluent that covers these compounds, and would effluent concentrations be expected to increase significantly?

July., 2�, 1999 i 'i F '. � f �::. r, This letter is a notification to you of a proposed change to the DuPont —Fayetteville Works wastewater routing system. The change will not alter the composition, monitoring, or reporting of this site's final effluent water quality. As part of major expansion at this site, a trench system that conveys non -contact cooling water from the Nafion® manufacturing area to our woodlined ditch upstream of Outfall 002 needs to have to its slope changed. This change in slope would result in the pipe conveying the treated Outfall 001 effluent to the same woodlined ditch being suspended in air above the trench, versus its current status of running underground beneath the trench. To deal with this situation, we are planning to have the pipe conveying the Outfall 001 effluent empty into the trench, commingle with the non -contact cooling water of the trench, and a new pipe system would then convey the combined water stream to the woodlined ditch and ultimately to Outfa11002. Since this change is downstream of Outfall 001, the requirements for Outfall 001 would be completely unaffected. Also, as the- two water streams affected by the change are currently FN��n� discharged into the woodlined ditch and completely mixed before reaching Outfall 002, the ��,P1tha,���requirements for Outfa11002 would be completely unaffected by this change. 1��aF� c"�`a`A1 �� If _you have any questions, please feel free to call me at (910) 678-1155.
