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 23, 2022. The Division is hereby notifying you that permit SW8970847 has been
renewed, updated, and re -issued on August 24, 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 March 7, 2030 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

PERMISSION IS HEREBY GRANTED TO
Marine Corps Base Camp Lejeune
Tactical Support Van Pad
Canal Street, Camp Lejeune, Onslow County
FOR THE
construction, management, operation and maintenance of built -upon area (BUA) for one (1) area of
redevelopment (the "redevelopment area") as well as BUA draining to one (1) wet detention pond
("stormwater control measures" or "SCMs") 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 March 7, 2030 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

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.
APPLICABLE RULES. The drainage area identified as SW8 970219 Proposed Permit Boundary
is subject to the 1995 Rules and the 2017 Rules and as clarified in the 1995 Rules and the 2017
Rules specific conditions listed herein.
BUA REQUIREMENTS. The maximum amount of BUA allowed for the entire project is 376,357
square feet. The runoff from all BUA within the permitted high density drainage area of this
project must be directed into the permitted SCM. The BUA requirements and allocations for this
project are as follows:
Page 1 of 5

a. REDEVELOPMENT. The redevelopment portion of this project is exempt from permitting
requirements under the following conditions:
i. The project must be constructed as shown on the submitted plans.
ii. The redevelopment area proposes 62,058 square feet of BUA, which does not
exceed the existing BUA of 62,058 square feet. This permit does not provide any
allocation of BUA for future development within this redevelopment area.
iii. The proposed stormwater control piped collection system provides equal protection
of surface waters as the existing stormwater control piped collection system.
b. SCM BUA LIMITS. The SCM has been designed to handle the runoff from 314,299 square
feet of BUA within the delineated drainage area. The BUA for the future development is
limited to 64,314 square feet.
PERVIOUS AREA IMPROVEMENTS. At this time, none of the pervious area improvements
listed in G.S. 143-214.7(b2) or the Stormwater Design Manual have been proposed for this
project. Pervious area improvements will be allowed in this project if documentation is provided
demonstrating those improvements meet the requirements of the stormwater rule.
4. SCM REQUIREMENTS. The SCM requirements for this project are as follows:
SCM DESIGN (1995 Rules). The SCM is permitted based on the following design criteria

Wet Detention Basin Operation and Maintenance Agreement
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,
pretreatment including forebays and the vegetated filter if one is provided.
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.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.
