Subject: State Stormwater Management Permit No. SW8 110907
Temporary Lodging Facility Addition
High Density Commercial Wet Detention Pond Project
Onslow County
Dear Mr. Baker
Dee Freeman
Secretary
The Wilmington Regional Office received a complete modified Stormwater Management Permit
Application for the Temporary Lodging Facility Addition on August 3, 2012. Staff review of the plans
and specifications has determined that the project, as proposed, will comply with the Stormwater
Regulations set forth in Title 15A NCAC 2H.1000 and Session Law 2008-211. We are forwarding
Permit No. SWS 110907 dated August 6, 2012, for the construction, operation and maintenance of
the BMP's and built -upon areas associated with the subject project. Please add the attached
approved plans to the previously approved plan set.
This permit shall be effective from the date of issuance until December 7, 2021, and shall be 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 permit, or to renew the permit, will
result in future compliance problems.
The following modification is included and covered by this permit:
• Increasing the drainage area and impervious area associated with the previously approved
wet detention pond. The additional areas are a result of the expansion to the existing office
building.
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

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, or need additional information concerning this matter, please contact
Christine Nelson, at [phone].

PERMISSION IS HEREBY GRANTED TO
MCB Camp Lejeune
Temporary Lodging Facility Addition
Holcomb Blvd, Camp Lejeune, Onslow County
FOR THE
construction, operation and maintenance of one (1) wet detention pond in compliance with
the provisions of 15A NCAC 2H .1000 and Session Law 2008-211 (hereafter collectively
referred to as the "stormwater rules') the approved stormwater management plans and
specifications and other supporting data as attached and on file with and approved by the
Division of Water Quality and considered a part of this permit.
This permit shall be effective from the date of issuance until December 7, 2021, 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. This stormwater system has been approved for the management of stormwater runoff
as described in Section 1.8 on page 3 of this permit. The stormwater control has been
designed to handle the runoff from 45,352 square feet of impervious area.
3. A 30' wide vegetative buffer must be provided adjacent surface waters, measured
horizontally from and perpendicular to the normal pool of impounded structures, the
top of bank of both sides of streams and rivers and the mean high water line of tidal
waters.
4. A vegetated filter strip is not required for this pond as it has been designed for a 90%
total suspended solids removal efficiency.
5. The tract will be limited to the amount of built -upon area indicated on page 3 of this
permit, and per approved plans. This permit does not provide any allocation of built -
upon area for future development.
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.

TFL Renovation - SW8 110907
Gentlemen,
I have finished looking through the submittal to modify the state stormwater permit for the TLF facility at Camp Lejeune,
permit no. SW8 110907. The only items I need are the updated plan sheets detailing the modified outlet structure. As
we discussed in the meeting, if the pond is oversized, you may also want to consider including an allocation for future
impervious area within the set drainage area.
Since these are items we have already discussed, I'm not sending the full blown letter requesting additional
information. Please get the updated plans and any other updated documentation to me by August 3. Let me know if
you have any questions.
Thanks,
Christine

STORM WATER NARRATIVE
Modification of SW Permit # 12-0030
Express Request Submittal
June 29, 2012
I. GENERAL INFORMATION
Project Name & Address: Marine Corps Base Camp LeJeune
Temporary Lodging Facility (TLF) Addition
Holcomb Boulevard
Camp LeJeune, NC 28547
Property Ownership: U.S. Government
Acres Disturbed: < 3 acres
Wetlands Disturbed: There are no wetlands within the limits of construction.
Existing Permits: None known for this project site, but will be verified prior to
Application Meeting
II. EXISTING CONDITIONS
The site is located in an urbanized area on the Marine Corps Base Camp
Lejeune along Holcomb Boulevard, approximately 1400 feet southwest of Birch
Street. The project site is currently developed with an existing Temporary
Lodging Facility. The existing permit (#12-0030) provides for addition of a single
three story structure to the eastern edge of the TLF. This modification request is
to expand the existing office building by an additional 1848 SF, collect the limited
drainage area serving this building and direct less than a quarter acre of
additional drainage to the permitted wet detention facility.
The Marine Corps Base Camp Lejeune owns, maintains and manages the
wastewater collection and water distribution systems on base. The development
is served by collection and distribution mains along the adjacent roadways.
The existing facility is collected in a storm sewer system that drains to an
unnamed tributary. This tributary runs along the northern perimeter of the TLF,
and ultimately connects to Beaverdam Creek.

III. PROPOSED DEVELOPMENT
The proposed project consists of a net increase of impervious surface of
approximately 15,881 SF. The project is a high density commercial design
located within a coastal county. The Coastal Counties Stormwater Law (Session
Law 2008-211) will apply.
This project will be designed, permitted, and constructed in two phases (the
original "Addition" project and the "Renovation" project now proposed).
There are no off -site roadway improvements required for this project.
Stormwater is proposed to be collected for the new and expanded building
footprints and new parking area, routed through a wet detention basin pond (85%
TSS Removal) to achieve the prescribed stormwater treatment.
The following pages provide the Quadrangle, and aerial vicinity map and an
excerpt from the Environmental Sensitivity Map for Onslow County.
