Subject: Modification of NPDES Permit NC0066397
Casar Elementary School %V'vVrP
Cleveland County
The Division issued the subject permit on October 9, 2003. That permit contained two typographical errors
regarding the permitted flow at the facility: 0.066 MGD was written where 0.0066 MGD should have been.
This modification corrects the two typographical errors. No other changes to the permit have been made.
Please find enclosed the revised pages, which 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 Charles Weaver of the NPDES
Unit at [phone], extension 511.
