The NC 2007-2014 Water Quality Standard (WQS) Triennial Review was approved by the US EPA
on April 6, 2016 with some revisions. The approved WQS no longer includes a standard for Manganese. We
have therefore removed the Manganese limit from permit NC0085154.
This permit modification 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 October 15, 2007 (or as subsequently amended). Insert the attached page into your
permit and discard the old page.
This modified permit includes the following changes from your current permit:
D The Manganese limit has been deleted.
If any parts, measurement frequencies or sampling requirements contained in this 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
(6714 Mail Service Center, Raleigh, North Carolina 27699-6714). Unless such demand is made, this
decision shall be final and binding.
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 any other Federal, State, or Local governmental
regulation. If you have any questions concerning this matter, please contact Charles H. Weaver at (919)
807-6391 or via e-mail [[e-mail]].
