Dear Mr. Condrey:
A review of the subject permit by Division personnel noted three typographical errors in Section
A.(1.) Effluent Limitations and Monitoring Requirements. This permit minor modification corrects
the following items and is effective on April 1, 2016:
• Instream monitoring frequency for dissolved oxygen, conductivity, and temperature have
been changed to "Footnote 7", which requires that instream monitoring shall be conducted
3/week during June, July, August and September and 1/week during the rest of the year.
Please find the enclosed revised permit page. The revised page should be inserted into your permit.
The old page 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 Agreements between North
Carolina and the U.S. Environmental Protection Agency dated October 15, 2007 (or as subsequently
amended).
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
