Dear Mr. Gilbert:
On April 22, 2008, the Division of Water Quality issued NPDES Permit No. NC0088722 for Killian Creek

disinfection. 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. If you have any
