STATE STORMWATER MANAGEMENT PERMIT
HIGH DENSITY DEVELOPMENT
In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North
Carolina as amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
USMCB Camp Lejeune
TECOM (MCCSSS) Interim Facilities-Humvee Garage
Neuse Road, Camp Johnson Area, MCB Camp Lejeune, Onslow County
FOR THE
construction, operation and maintenance of two (2) wet detention ponds in compliance with the
provisions of 15A NCAC 2H .1000 (1995 Rules) as amended by Session Law (SL) 2006-246 and as
subsequently amended on January 1, 2017 (2017 Rules), as applicable (collectively, the "stormwater
rules') and the approved stormwater management plans and specifications and other supporting data
as attached and on file with and approved by the Division of Energy, Mineral and Land Resources
(the "Division" or "DEMLR") and considered an enforceable part of this permit.
This permit shall be effective from the date of issuance until December 30, 2029, and shall be subject
to the following specified conditions and limitations:
I. DESIGN STANDARDS
This permit is effective only with respect to the management and volume of stormwater
described in the application and other supporting data. The maximum amount of built -upon
area (BUA) allowed for the entire project is 91,801 square feet.
2. This stormwater system has been approved for the management of stormwater runoff as
described in Section 1.6 this permit. The stormwater control measures labeled Pond 1 and
Pond 2 have been designed to handle the runoff from 45,871 and 45,930square feet of built -
upon area, respectively. This permit does not provide any allocation of built -upon area for
future development.
All stormwater collection and treatment systems must be located in either dedicated common
areas or recorded easements. The final plats for the project will be recorded showing all such
required easements, in accordance with the approved plans.
The runoff from all built -upon area within the permitted drainage area of this project must be
directed into the permitted stormwater control system.
A vegetated filter strip is not required for these ponds as they have been designed for a 90%
total suspended solids removal efficiency.
The built -upon areas associated with this project shall be located at least 30 feet landward of
all perennial and intermittent surface waters.

flushing of sediment through the emergency drain should be minimized to the
maximum extent practical.
— Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month and
