High Density Wet Pond Project
Dear Mr. Lacy:
The Stormwater Permitting Unit received a complete Stormwater Management Permit Application for
the Grays Creek Middle School on Celebration Drive on July 3, 2009. 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. SW6090701, dated July 8, 2009, 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 July 7, 2019, 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

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
