East Carolina University Grounds Complex Relocation
Pitt County
Dear Mr. Bagnell:
The Stormwater Permitting Unit received a complete Stormwater Management Permit Application for
East Carolina University Grounds Complex Relocation on August 18, 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. SW7090811, dated August 19, 2008, for the construction, operation and maintenance of
the subject project and the stormwater BMPs. I y R l
f
This permit shall be effective from the date of issuance until gust 18, 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 stornwater 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 27611-7447. Unless such demands are made this permit shall be final and
binding.
This project will be kept on file at the Washington Regional Office. If you have any questions, or need
additional information concerning this matter, please contact Mike Randall at [phone]; or
[e-mail].
Sincerely, �

Re: 50142.02 — East Carolina University — Grounds Complex Relocation
Dear Mike:
Construction of the storm water management devices for the referenced project, as
permitted under the North Carolina Department of Environment and Natural Resources
Division of Water Quality Storm Water Permit Number SW7090811, has been
completed. A copy of the Designer's Certification covering the wet detention pond is
enclosed
Due to the fact that the observed stabilized groundwater elevation at the time of
construction was approximately 10 — 12 inches below the design elevation, the pond
littoral shelf was lowered such that the installed plants would appropriately engage the
permanent pool. The pond outlet orifice and overflow structures remain unchanged
from the design drawings. Accordingly, the water quality orifice is positioned
approximately 10 — 12 inches above the pool elevation. A modified permit application is
included with this submittal to document the design alteration.
Please let us know if you require anything further
