Dear Mr. Paul:
Effective August 1, 2013 the State Stormwater 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 stormwater 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 issuance of the permit.
The Wilmington Regional Office received a complete 8 year Stormwater Management Permit Renewal Application for
the subject project on July 27, 2021. The Division is hereby notifying you that permit SW8 091111 has been renewed
on July 29, 2021, and shall be effective until February 20, 2029. For your records, please find enclosed a renewed,
updated, and re -issued permit and a copy of the renewal application. Please keep this permit on file at all times. Please
note that the renewed, updated, and re -issued permit does not impose new or different terms; it merely restates some of
the previous terms to provide you with a better understanding of your obligations under the permit.
The renewal and reissuance of this stormwater permit does not imply that the site is currently in compliance with the
terms and conditions of this state stormwater permit. The plans originally approved on May 7, 2010 and most recently
revised on March 17, 2011 will remain in full force and effect in accordance with the regulations set forth in Title 15A
NCAC 2H.1000.
This permit is subject to the conditions and limitations as specified therein. Please pay special attention to the
conditions listed in this permit regarding the Operation and Maintenance of the BMP(s), recordation of deed
restrictions, procedures for changes of ownership, transferring the permit, and renewing the permit Failure to establish
an adequate system for operation and maintenance of the stormwater management system, to record deed restrictions,
to transfer the pemut, or to renew the permit, 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 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

STATE STORMWATER MANAGEMENT PERMIT
HIGH DENSITY COMMERCIAL 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 Marine Corps Base, Camp Lejeune
Courthouse Bay BEQ, P-1142
Grace Street, Camp Lejeune, Onslow County
FOR THE
construction, operation and maintenance of one (1) infiltration basin with storage in a remote basin in
compliance with the provisions of Session Law 2008-211 and 15A NCAC 2H .1000 (hereafter
collectively and separately referred to as the "stormwaterrules'� 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 February 20, 2029, and shall be subject
to the following specified conditions and limitations:
I. DESIGN STANDARDS
1. This permit is effective only with respect to the nature and volume of stormwater described in
the application and other supporting data.
2. Within the redevelopment portion of the project area, there is a total of 119,620 square feet of
existing impervious area. This project proposes a total of 96,773 square feet of impervious
area, as shown on the approved plans, which is a reduction of 22,847 square feet of
impervious area. Due to a portion of the proposed impervious area being located closer to the
surface water, the runoff from 33,859 square feet of impervious area will be collected and
treated in the infiltration basin. The remaining 62,914 square feet of impervious area will be
treated via sheet flow through vegetated areas prior to entering an existing ditch, which has
been found to be equal or better stormwater control than had previously existed.
3. This stormwater system has been approved for the management of stormwater runoff as
described in Section 1.8 on page 2 of this permit. The infiltration basin with storage in the
remote basin has been designed to handle the runoff from 267,686 square feet of impervious
area. This permit does not allocate any impervious area for future development.
4. This infiltration basin 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.
Page 1 of 5
State Stormwater Management Systems
Permit No. SW8 091111
5. 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.
6. The runoff from all built -upon area within the permitted drainage area of this project must be
directed into the permitted stormwater control system.
Under redevelopment guidelines, a 30 foot wide vegetated buffer must be provided adjacent to
surface waters measured perpendicular to and horizontally from, the normal pool of
impounded structures, the top of bank of streams and rivers, and the mean high water mark of
tidal waters.
8. The following design criteria have been permitted for the infiltration basin stormwater facility

Dry Extended 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 dry extended detention basin system is defined as the dry detention basin, outlet
structure, 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:
— The drainage area will be managed to reduce the sediment load to the dry
extended detention basin.
— Immediately after the dry extended detention basin is established, the vegetation
will be watered twice weekly if needed until the plants become established
(commonly six weeks).
— No portion of the dry extended detention pond will be fertilized after the first
initial fertilization that is required to establish the vegetation.
— I will maintain the vegetation in and around the basin at a height of
approximately six inches.
— Once a year, a dam safety expert will inspect the embankment.
After the dry extended detention basin is established, it will be inspected once a quarter
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.

Filter Strip, Restored Riparian Buffer and Level Spreader
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:
— Immediately after the filter strip is established, any newly planted vegetation
will be watered twice weekly if needed until the plants become established
(commonly six weeks).
— Once a year, the filter strip will be reseeded to maintain a dense growth of
vegetation
— Stable groundcover will be maintained in the drainage area to reduce the
sediment load to the vegetation.
— Two to three times a year, grass filter strips will be mowed and the clippings
harvested to promote the growth of thick vegetation with optimum pollutant
removal efficiency. Turf grass should not be cut shorter than 3 to 5 inches and
may be allowed to grow as tall as 12 inches depending on aesthetic requirements
(NIPC, 1993). Forested filter strips do not require this type of maintenance.
— Once a year, the soil will be aerated if necessary. VE
Once a year, soil pH will be tested and lime will be added if ne s y'.

After the filter strip is established, it will be inspected quarterly and Ithin 24 hours
