Box 550 Newton, NC 28658 Dear Mr. Sigmon, Coleen H. Sullins, Director Division of Water Quality Subject: Error correction Permit NC0036196 Clark Creek WWTP Catawba County On January 8, 2009, the Division of Water Quality issued NPDES Permit No. NC0036196 for Clark Creek WWTP. Due to our oversight the copper monitoring was not removed from the effluent pages. Therefore, the Division made a correction to the Effluent pages. Please insert the enclosed corrected effluent sheets and discard the old sheets. This permit modification becomes effective on the effective date of the permit. All other terms and conditions in the original permit remain unchanged and in full effect. These modifications are issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency dated December 6, 1983. If any parts, measurement frequencies or sampling requirements contained in this 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 in the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of Administrative Hearings, Post Office Drawer 11666, Raleigh, North Carolina 27604. Unless such demand is made, this decision shall be final and binding.
