Dear Mr. Arwood:
The Division issued the subject permit on March 13, 2000. A review of the new permit by personnel in the
Mooresville Regional Office noted a typographical error in the permit. This permit modification corrects the error on
the Effluent Limitations and Monitoring Requirements page (flow Emit).
Please find enclosed the revised permit page. The revised page 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.
If you have any questions concerning this permit modification, please contact Charles Weaver at [phone],
extension 511.
Sincerely,
K r T. Stevens

Dear Mr. Stevens:
We noticed on the NPDES Permit for Knollwood Elementary School in Rowan County
issued on March 13, 2000 that the flow (monthly average requirement) was 0.0011
MGD.
On the previous permit, it was 0.011 MGD a day. Was this indeed supposed to change
or is this a typographical error?
Please advise. Thank you.
Sincerely,
