Klimek, P.E., Director Division of Water Quality May 19, 2003 Subject: Modification of NPDES Permit NCO060755 Saddlewood WW`TP Gaston County The Division received your request for clarification regarding the subject permit on May 1, 2003. You correctly noted a typographical error in Part I. A. (1.). We apologize for any confusion this may have caused. This modification corrects the error, identifying that weekly temperature monitoring will be done instream (in addition to daily monitoring at the effluent). This modification is to correct the typographical error only; no other changes to the permit have been made. Please find enclosed the revised page, which should be inserted into your permit. The old page may then be discarded. 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. 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.

MAY - 1 2003 We are in receipt of the permit renewal for this facility effective May 1, 2003. We just caught what appears to be a typographical error in the limits and monitoring section. As you can see from the page attached [Section (A)(1)], temperature for effluent is listed as both Daily and Weekly which makes no sense. We would appreciate your assistance to correct this discrepancy and forward a revised page at your earliest convenience. We will abide by the old permit for this parameter until we receive your response. If you should have any questions, please do not hesitate to contact me at 704-525-7990, Ext. 216 or e-mail me at lashua_cws@bellsouth.net. Thank you in advance for your assistance.
