Hoke County
Dear Mr. Floyd:
MW
Dee Freeman
Secretary
The Stormwater Permitting Unit received a complete Stormwater Management Permit Application for Turnberry
Section I on August 11, 2011. Staff review of the plans and specifications has determined that the project, as
proposed, will comply with the Stormwater Regulations set forth in Title 15A NCAC 2H.1000 and Session Law
2006-246. We are forwarding Permit No. SW61 10803, dated August 29, 2011, for the construction, operation and
maintenance of the subject project and the stormwater BMPs.
This permit shall be effective from the date of issuance until April 13, 2018, and shall be subject to the conditions and
limitations as specified therein. Please pay special attention to the Operation and Maintenance requirements in this
permit. Failure to establish an adequate system for inspection and maintenance of the stormwater management system
will result in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to request an
adjudicatory hearing upon written request within thirty (30) days following receipt of this permit. 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, P.O. Drawer 27447, Raleigh, NC 2761 1-7447. Unless such demands are made
this permit shall be final and binding.
This project will be kept on file at the Fayetteville Regional Office. If you have any questions, or need additional
information concerning this matter, please contact Mike Randall at (919) 807-6374; or mike.randall@ncdenr.gov.
Sincerely,
for Coleen H. Sullins
