Insert the attached page into your permit and discard the old page. This modified permit includes the following changes from your current permit: ➢ The Manganese limit has been deleted, effective 9/1/2016. 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 [charles.weaver@ncdenr.gov]. Sincerely S. Jay Zimmerman, P.G.

I spoke with Jennifer Bothwell explaining that there is no longer a Manganese standard. I mentioned to her that she should discuss this with the regional office about any enforcement discretion in regard to applying a Manganese limit until such time that we can send out letters. I'm forwarding this to Charles. He has or will be sending out letters for WTP that had Manganese limits. Sincerely, Derek C Denard Environmental Specialist Compliance & Expedited Permitting Unit N.C.
