Subject: NPDES Permit Correction
Permit Number NC0020664
Spindale WWTP
Rutherford County
Dear Mr. Hodge:
It has come to our attention that the upstream and downstream sampling locations were
inadvertently switched during your recent permit renewal. Division personnel have corrected this error
in Part I, Sections A(1), A(2), and A(3) of the subject permit. The attached permit pages should be
placed in the permit and the old pages discarded. This permit correction 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 9, 1994 (or as subsequently
amended).
If you have any questions or need additional information, please do not hesitate to contact Toya
Fields of my staff at [phone], extension 551.
