Subject: Permit Correction of NPDES Permit NCO047091
Silver Maples Community WWTP
Cabarrus County
Dear Mr. Boggs: -
Division personnel have reviewed and corrected parts of your existing NPDES Permit to address typographical errors made during the
renewal and issuance process of your existing NPDES permit which was issued December 22,2008. Attachment A. (1) "Effluent
Limitations and Monitoring Requirements", indicates,the daily maximum BODs limit as 9.5 mg/L which was in error. The correct daily
maximum average for BOD should have been 19.5 mg/L.
We are forwarding you this new Attachment A. (1)"Effluent Limitations and Monitoring Requirements"which reflects the correct Daily
'maximum effluent limit for BOD at 19.5 mg/L. You should replace your existing Attachment A. (1)"Effluent Limitations and
Monitoring Requirements'with this corrected Attachment A. (1).
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 October 15,2007 (or as subsequently
amended). If any parts,measurement frequencies or sampling requirements contained in this permit correction 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 150E 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 Bob
Guerra at telephone number(919) 807-6387.
