Dear Mr. Paul:
The Division of Energy, Mineral and Land Resources received a complete 8-year Permit Renewal Application for
the subject permit on August 10, 2022. The Division is hereby notifying you that permit SW8100701 has been
renewed, updated, and re -issued on September 6, 2022, as attached. Please be aware that the renewal and re -
issuance of this stormwater permit does not imply that the site is currently in compliance.
This permit shall be effective until December 31, 2029 and does not supersede any other agency permit that may
be required. The project shall be subject to the conditions and limitations as specified therein. This permit does
not impose new or increased stormwater control requirements; it clarifies the rules and requirements of this
program to provide you with a better understanding of your obligations under this permit. Failure to comply with
these requirements will result in future compliance problems. Please note that this permit is not transferable
except after notice to and approval by the Division.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to request
an adjudicatory hearing by filing a written petition with the Office of Administrative Hearings (OAH). The
written petition must conform to Chapter 150B of the North Carolina General Statutes and must be filed with the
OAH within thirty (30) days of receipt of this permit. You should contact the OAH with all questions regarding
the filing fee (if a filing fee is required) and/or the details of the filing process at 6714 Mail Service Center,
Raleigh, NC 27699-6714, or via telephone at 919-431-3000, or visit their website at www.NCOAH.com. Unless
such demands are made this permit shall be final and binding.
If you have any questions concerning this permit, please contact Ashley Smith in the Wilmington Regional
Office, at [phone] or [e-mail].
Sincerely,
Brian Wrenn, Director

POST -CONSTRUCTION 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
US MCB Camp Lejeune
Birch Street Physical Fitness Center, P-1160
Birch Street, 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 and Session Law 2008-211 (hereafter collectively referred to as the
"stormwater rules') as outlined in the application, approved stormwater management plans,
supplement, calculations, operation and maintenance agreement, recorded documents,
specifications, and other supporting data (the "approved plans and specifications") as attached and/or
on file with and approved by the Division of Energy, Mineral and Land Resources (the "Division" or
"DEMLR"). The project shall be constructed, operated and maintained in accordance with these
approved plans and specifications. The approved plans and specifications are incorporated by
reference and are enforceable part of this permit.
This permit shall be effective from the date of issuance until December 31, 2029 and shall be subject
to the following specified conditions and limitations. The permit issued shall continue in force and
effect until the permittee files a request with the Division for a permit modification, transfer, renewal, or
rescission; however, these actions do not stay any condition. The issuance of this permit does not
prohibit the Director from reopening and modifying the permit, revoking and reissuing the permit, or
terminating the permit for cause as allowed by the laws, rules, and regulations contained in Title 15A
NCAC 2H.1000 and NCGS 143-215.1 et.al.
I. DESIGN STANDARDS
This permit is effective only with respect to the nature and volume of stormwater described in
the application and other supporting data.
This stormwater system has been approved for the management of stormwater runoff as
described in Section 1.9 of this permit. The runoff from all built -upon area within the permitted
drainage areas of this project must be directed into the permitted stormwater control systems.
The stormwater controls, Pond 1 and Pond 2, have been designed to handle the runoff from
119,420 and 202,745 square feet of impervious area, respectively.
3. The maximum amount of built -upon area allowed for the entire project is 322,165 square feet.
4. The additional bioretention cells and permeable pavement shown on the plans do not meet
State Stormwater BMP design requirements and therefore are not considered a part of the
approved state stormwater treatment system. These additional measures are incorporated
only by reference and are not enforceable parts of the permit.

Post -Construction Stormwater Management
Permit No. SW8 100701
The drainage areas will be limited to the amounts of built -upon area indicated in Sections 1.2
and 1.9 of this permit, and per approved plans. This permit does not provide any allocation of
built -upon area for future development.
A vegetated filter strip is not required for this pond as it has been designed for a 90% total
suspended solids removal efficiency.
The project shall maintain a 50' wide vegetated buffer adjacent all surface waters, measured
horizontally from the normal pool of impounded structures, the bank of each side of rivers and
streams and the mean high water line of tidal waters. The wet detention pond(s) may not be
located within the buffer and no built -upon area is allowed within the buffer.
All runoff being directed into wetlands shall flow into and through those wetlands at a non -
erosive velocity of 2 fps or less.
The following design criteria have been provided in the wet detention pond and must be
maintained at design condition:

I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
The wet detention basin system is defined as the wet detention basin,

This system (check one):
❑ does ❑ does not incorporate a vegetated filter at the outlet.
This system (check one):
❑ does ❑ does not incorporate pretreatment other than a forebay.
Important maintenance procedures:
— Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
— No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
— Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
— If the basin must be drained for an emergency or to perform maintenance, the
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
within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a
Coastal County). Records of operation and maintenance should be kept in a known set
location and must be available upon request.
