Dear Mr. Bumgarner:
The Division received your application for a wastewater discharge permit on January 13, 2005.
Division personnel have reviewed and approved your application. Accordingly, we are forwarding the
attached NPDES discharge permit. This permit is 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 May 2004, and as subsequently amended.
A Total Residual Chlorine (TRC) limit has been added to this permit. Because you may need time to
make modifications to your plant in order to comply with this new condition, the TRC limit will not take effect
until February 1, 2007.
If any parts, measurement frequencies or sampling requirements contained in this permit 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,
6714 Mail Service Center, Raleigh, North Carolina 27699-6714. Unless such demand is made, this decision
shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may
require modification or revocation and reissuance of the permit.
This permit does not affect the legal requirements to obtain other permits which may be required by
the Division of Water Quality or permits required by the Division of Land Resources, the Coastal Area
Management Act or any other Federal or Local governmental permit that may be required.
If you have any questions concerning this permit, please contact Vanessa Manuel at telephone
number [phone], extension 532.
Sincerely,
