Dear Ms. Maranville:

NPDES Permit Correction
NPDES Permit No. NC0044962
North Stokes High School
Stokes County
On January 14, 1997, the Division issued the subject permit. A review of the permit file has
indicated that an error was inadvertently made in the permit. Accordingly, we are forwarding
herewith modifications to the subject permit to correct the error. This permit correction affects the
effluent limitations page by changing the type of sample to be collected for chronic toxicity. This
sampling change will allow for a more accurate sampling of the facility discharge.
Please find enclosed the amended effluent page which should be inserted into your permit. The old
pages should be discarded. All other terms and conditions contained in the original permit remain
unchanged and in full effect. This permit correction is issued pursuant to 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 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 27447, Raleigh, North Carolina 27611-
7447. Unless such demand is made, this decision shall be final and binding.
If you have any questions concerning these permit modifications, please contact Charles Weaver at
telephone number [phone], extension 511.
