Dear Mr. Paul:
Effective August 1, 2013 the Post -Construction Stormwater Management Program has been transferred from the
Division of Water Quality ("DWQ") to the Division of Energy, Mineral and Land Resources ("DEMLR" ). All
previous references to DWQ will remain in older permits issued prior to August 1, 2013 until they are modified.
Please note that this permit will now reference DEMLR as the Division responsible for enforcement of the permit.
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 SW8091 113 has been
renewed, updated, and re -issued on September 14, 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 January 1, 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
an adjudicatory hearing by filing a written petition with the Office of Administrative Hearings (OAH). The
written petition must conform to Chapter 150E 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.NCOA14.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,

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
Commanding Officer US Marine Corps Base Camp Lejeune
P688 Apron Expansion Phase Il, P683IP687 MV-22 Hangar and PO Parking Garage
Curtis Road, Camp Lejeune, Jacksonville, Onslow County
FOR THE
construction, operation and maintenance of one (1) infiltration basin, four (4) sand filters and a
Rainwater Harvesting System, in compliance with the provisions of Session Law 2008-211 and 15A
NCAC 2H .1000 (hereafter collectively and separately referred to as the "stormwater rules') and 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 January 1, 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
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 Sections 1.9, 1.10 and 1.11 of this permit. The stormwater controls labeled IB-1,
SF-1, SF-2, SF-3, SF-4 and RHS have been designed to handle the runoff from 2,439,933 sf;
56,613 sf; 81,644 sf; 115,666 sf; 76,898 sf; and 67,150 sf of built -upon area, respectively.
Infiltration Basin I13-1 has 38,712 square feet of future allocation available.
3. The infiltration basin I13-1 must be operated with a 50 foot vegetated filter, designed to pass
the peak flow from the 10 year storm in a diffuse and non -erosive manner. The four sand
filters are not required to be operated with a vegetated filter.

Post -Construction Stormwater Management
Permit No. SW8 091113
4. The RHS cistern is designed to collect the runoff from 67,150 sf of the MV-22 roof area
(horizontal component), reuse it as airplane washdown water and bypass any excess design
overflows to SF-2. The RHS cistern is designed to hold 80,000 gallons of runoff, or 10,695
cubic feet. The dedicated use is 57,600 gallons a week for airplane washdown water. The
hose bibs provided for airplane washing operations will automatically pull from the RHS tank.
When the RHS tank goes dry, a sensor will close the valve and water will be supplied from the
public line. The washdown area will have a valve to the sewer system which must be opened
during washing operations to allow that wastewater to drain to the sewer system, and then
closed so that new stormwater runoff can be directed to the RHS system. Adequate signage
and instructions must be provided in the washdown area.
5. The drainage area and built -upon area for each BMP will be limited to those amounts indicated
in Sections 1.9, 1.10 and 1.11 of this permit, as provided in the calculations, and as depicted on
the approved plans.
6. 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.
7. The runoff from all built -upon area within the permitted drainage areas of this project must be
directed into the permitted stormwater control system.
8. The project shall provide a 50 foot wide vegetated buffer adjacent all surface waters,
measured horizontally from and perpendicular to the normal water line of impounded
structures, the top of bank of both sides of streams and rivers, and the mean high water line of
tidal waters. Except as allowed for water -dependent uses, no built -upon area can be
constructed in the buffer.
9. The following design criteria have been permitted for the proposed sand filters and must be
provided and maintained at design condition:

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.
Important maintenance procedures:
— The roof area will be maintained to reduce the debris and sediment load to the
system. Excess debris can clog the system and lead to bypass of the design
storm, and reduced reuse volume.
— To ensure proper operation as designed, a licensed Professional Engineer,
Landscape Architect, or other qualified professional will inspect the system
annually.
— The system components will be repaired or replaced whenever they fail to
function properly.
— If the outlet is metered, use must be recorded at a minimum of monthly. These
records shall be kept on site for inspection by DWQ.
The system will be inspected by the owner/operator at least monthly and within 24
hours after each rain event. Records of operation and maintenance will be kept in a
known set location and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

Sand Filter 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.
Important maintenance procedures:
— The drainage area will be carefully managed to reduce the sediment load to the sand filter.
— The sedimentation chamber or forebay will be cleaned out whenever sediment depth exceeds
six inches.
— Once a year, sand media will be skimmed.
— The sand filter media will be replaced whenever it fails to function properly after maintenance.
The sand filter will be inspected quarterly 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 will be kept in
a known set location and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall be repaired
immediately.
