Subject: NPDES Permit Correction
NPDES Permit #NC0044440
Cherryville WWTP
Gaston County
Dear Mr. Childers:
On June 26, 1995, the Division of Environmental Management issued NPDES Permit No.
NC004'1110 to the Town of Cherryville. Based on a review of the facility rating, it has been determined
that the subject treatment plant was actually a Class III facility at the time of permit issuance, rather than a
Class II. Therefore, in accordance with Division regulation 15A NCAC 2B .0500, the monitoring
frequencies for BOD5, TSS, fecal coliform, NH3-N, DO, temperature, conductivity, pH and total residual
chlorine have been revised. The attached effluent sheets have been modified to relect these changes.
Please replace the existing sheets with the enclosed effluent sheets. This modification becomes effective
on October 1, 1995, to allow sampling and laboratory schedules to be revised.
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 this correction is 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 questions concerning this permit, please contact Mr. Greg Nizich at telephone
number (919) 733-5083, extension 541.
Sincerely,
A. Preston Howard, Jr., P.E.
