Dear Mr. Baker:
Alan W. Klimek, P.E. Director
Division of Water Quality
The Wilmington Regional Office received a complete modified Stormwater Management
Permit Application for Landing Helicopter Assault (LHA) Deck on January 16, 2007. 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. We are
forwarding Permit No. SW8 921101 dated January 17, 2007, for the construction of the subject
project.
This permit shall be effective from the date of issuance until January 17, 2017, and shall be
subject to the conditions and limitations as specified therein. Please pay special attention to
the Operation and Maintenance requirements in this permit. Failure to establish an adequate
system for operation and maintenance of the stormwater management system 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 upon written request within sixty (60) days
following receipt of this permit. This request must be in the form of a written petition,
conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of

Dear Linda:
RECEIVED
NOV 17 L1129
On October 27, 2006, the Regional Soil Scientist advanced a soil auger in the area ofthe
proposed infiltration basin for the LHA Deck. It was his recommendation that the basin be
elevated one foot to provide additional separation between the basin bottom and the underlying
confining soil layers. Enclosed please find for your records two copies of the project plans
which have been modified to elevate the basin bottom to one foot.
It is requested that you continue with your review of the Stor mvatcr Permit and if deemed
appropriate, issue the permit. Should you have any questions relating to this matter, please do
not hesitate to call.

Dear Linda:
In response to your June 19, 2006 letter requesting additional information for the referenced project.
Attached please find our resubmittal consisting of the following:
• Project Plans (Two Copies)
• Permit Application (Original and One Copy)
• Stormwater Calculations (Two Copies)
• Request for Soil Scientist Evaluation (One Copy)
Project plans have been modified to incorporate those comments which you offered. Specifically, an
infiltration basin has been designed in the area of the formerly designed sediment trap. The basin has
been designed to catch the full I '/z-inch runoff volume. I have utilized a project area which coincides
with the drainage basin present on the site. The government has modified the concrete pads slightly since
our original submission. The project calculations coincide with those impermeable areas depicted on the
project plans.
It is my understanding that Mr. Vincent Lewis, the Regional Soil Scientist, requires a site visit to evaluate
the soils on the site. I an submitting a request for him to schedule this at his earliest convenience.
It is requested that you continue with your review of the permit application. Should you have any
questions or need any additional information to process this request, please do riot hesitate to call.

All proposed infiltration areas and existing, active utility lines located within the proposed
basin/trench must be marked and flagged. If these areas are not flagged, the Soils Scientist
reserves the right to decline to do the investigation. If the proposed infiltration system will be
located in an area of existing pavement and there is no open area nearby, equipment capable of
breaking through the impervious layer must be provided. The soils investigation does not take
the place of a soils report prepared by an appropriate professional. The Soil Scientist will only
verify the soil conditions that are reported in the Soils Report, and make a determination as to the
suitability of the site to meet the infiltration design requirements under NCAC 2H.1000, and
assumes no liability should the system fail.

Stormwater Project No. SW8 921101 Mod.
LHA Deck
CC# N40085-05-B-6796
Onslow County
Dear Mr. Baker:
The Wilmington Regional Office received a Stormwater Management Permit Application for
LHA Deck on April 13, 2006. A preliminary review of that information has determined that the
application is not complete. The following information is needed to continue the stormwater
review:
Please either delineate all wetlands on site, disturbed or undisturbed, or note on
the plans that none exist.
The classification of this portion of the New River is SA HOW. Please revise the
application accordingly.
This is a permit modification, therefore, the project is subject to the current rules
and interpretations. As previously permitted in 1992, this project was considered
low density, however, under current interpretation, expanding this project to over
73,000 ft2 of built -upon area will result in a pocket of high density. The Division
requests that the project be redesigned to high density and incorporate the use of
an infiltration basin to treat the runoff from 1.5" of rain.
4. The Division issued a Certification of Compliance for the project under low
density on December 16, 1992, for a maximum of 54,450 ft2 of built -upon area.
Please explain why the existing amount of built -upon area reported on the
current application is 55,350 ft , which is 1,100 ft more than what was previously
allowed.
5. One of the plan sheets shows details for a storage shed, however, no shed is
shown on either the grading or layout plans.
6. The original project area in 1992 was 5 acres, verified by UTM coordinates
provided by the Base. This modification is now proposing a project area of 5.81
acres. Low density relies on much more than just moving the imaginary project
boundaries and meeting a magic number, as is evidenced by our determination
that his project is now high density, and must provide appropriate permanent
treatment for the runoff. Hopefully, the sediment trap can be modified to an
infiltration basin to meet the requirements of the stormwater rules. Oii

AE Project No. 05179
Dear Ms. Lewis:
On December 16, 1992, the Division of Water Quality issued a Low Density Stormwater Permit
for the LHA Simulator Pad at Marine Corps Base, Camp Lejeune. The approval was issued
under Stormwater Permit No. SW8 921101. In May 2004, Marine Corps Base, Camp Lejeune
requested that Avolis Engineering, P.A. submit a modification to this stormwater permit to
replace the steel plate simulator pad with a concrete landing deck. At that time, the Government
was not proposing to enlarge the LHA Deck area, but to merely replace it with a concrete surface
to the existing dimensions and grades. A plan revision to the existing stormwater permit was
issued on October 1, 2004.
At this time, Marine Corps Base, Camp Lejeune is requesting that the existing LHA Deck Pad be
enlarged slightly to more closely mimic the ship deck which it is intended to model. Increasing
the size of the LHA Deck Pad will increase the impermeable surfaces at the project site.
We are submitting the following information as a request for a modification to the existing
stormwater permit to allow for the increase in size of the simulator pad and the replacement of the
metal plate deck with a concrete surfacing.

STORMWATER NARRATIVE
LANDING HELICOPTER ASSAULT DECK, LHA DECK
CONSTRUCTION CONTRACT NO. N40085-05-B-6796
MARINE CORPS BASE, CAMP LEJEUNE
ONSLOW COUNTY, NORTH CAROLINA
This project entails the replacement of an existing metal plate LHA Deck which is located in the
southwestern training areas of Marine Corps Base, Camp Lejeune. The existing facilities include
a metal plate system which is anchored to the ground and provides a simulated ship landing deck
for helicopters. The plates are arranged to simulate the deck of ships on which the helicopters
would normally land at sea. A portable deck lighting system is present on the site as is a gravel
drive providing access to the site off of NC Highway 172. A vegetated swale is located along the
eastern side of the project site. All runoff from the impermeable surfaces on the site discharge in a
southeasterly direction towards this vegetated swale. The vegetated swale discharges in a
southerly direction towards a lower lying area which ultimately discharges to the New River.
It is proposed as a part of this project to replace the existing metal deck with a permanent
concrete deck material. In order to more closely simulate the ships landing deck, the pad will be
slightly enlarged. It is proposed that the landing pad be shifted no closer to the banks of the New
River than it exists today. In order to accommodate the enlarged size, the existing vegetated
swale located on the site will be shifted eastward slightly. In order to capture sediment during
construction and to provide a permanent means to provide diffuse flow of runoff from the project
site, a sediment trap will be installed at the end of the vegetated swale. The sediment trap was
sized to contain the one -inch design storm volume for this project. Any excess runoff volume will
cap the back slope of the sediment trap and will discharge in a diffuse flow across the existing
vegetation towards the New River.
It is proposed that a total of 73,260 square feet of impermeable surfaces exist after the
construction of this project within the project drainage basin. This represents an increase of
17,910 square feet over the impermeable surfaces that presently exist on the site. The revised
project built -upon area is 28.9%.
The original LHA Deck simulator was approved for construction under a Division of Water
Quality Stormwater Permit No. SW8 921101 issued on December 16, 1992. In order to
accommodate the proposed construction, a modification to this existing stormwater permit is
being requested.
