Permit NC0025321
Town of Waynesville IX/WI-P

Dear Mr. Vest:
On March 11, 2002, a final permit for the subject facility was sent to the Town of Waynesville. On March 25,
2002, I spoke with Keith Haynes of the Asheville Regional Office and he informed me that instream monitoring
locations listed in the permit were incorrect. These have been changed to reflect the instream monitoring points
listed in the previous permit.
Please find enclosed the revised permit pages. The revised pages should be inserted into your permit. The old
pages,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.
If you have any questions concerning this permit modification,please contact Natalie Sierra at [phone],
extension 551.
