Subject: Stormwater Permit No. SW8 080126
MCB Camp Geiger — Parade Deck
High Density Project
Onslow County
Dear Mr. Baker:
The Wilmington Regional Office received a complete Stormwater Management Permit
Application for MCB Camp Geiger — Parade Deck on February 6, 2008. 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 080126 dated February 6, 2008, for the construction of the subject project.
This permit shall be effective from the date of issuance until February 6, 2018, 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 150E of the North Carolina General Statutes, and filed with the Office of
Administrative Hearings, P.O. Drawer 27447, Raleigh, NC 27611-7447. 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 Chris Baker, or me at [phone].

Dear Mr. Baker:
Michael F. Easley, Govemor
William G. Ross Jr., Secretary
North Carolina Department of Environment and Natural Resources
Coleen 11. Sullins Director
Division of Water Quality
The Wilmington Regional Office received a Stormwater Management Permit Application for MCB Camp Geiger — Parade
Deck on January 28, 2008. A preliminary review of that information has determined that the application is not complete.
The following information is needed to continue the stormwater review:
On the stormwater application the latitude, longitude appear to be reversed, please correct.
The drainage basin is listed as the New River on the application. Camp Lejeune is in the White Oak
drainage basin, please correct.
A 2" diameter orifice is listed on the wet detention basin supplemental form. The plans call for a 1-1/2"
diameter orifice, please make the proper correction.
Please note that this request for additional information is in response to a preliminary review. The requested information
should be received by this Office prior to February 5, 2008, or the application will be returned as incomplete. The return of a
project will necessitate resubmittal of all required items, including the application fee.
If you need additional time to submit the information, please mail or fax your request for a time extension to the Division at
the address and fax number at the bottom of this letter. The request must indicate the date by which you expect to submit the
required information.
The construction of any impervious surfaces, other than a construction entrance under an approved Sedimentation Erosion
Control Plan, is a violation of NCGS 143-215.1 and is subject to enforcement action pursuant to NCGS 143-215.6A.
Please reference the Stale assigned project number on all correspondence. Any original documents that need to be revised
have been sent to the engineer or agent. All original documents must be returned or new originals must be provided. Copies
are not acceptable. If you have any questions concerning this matter please feel free to call me at [phone].

OF A NEW WET DETENTION BASIN AND A REDUCTION TO THE TREATMENT AREA OF THE
BASIN THAT IS PERMITTED UNDER STORMWATER PERMIT SW8 960501. THE
COMPLETED PARADE DECK WILL PROVIDE A PAVED PARADE DECK BETWEEN THE
EXISTING BARRACKS AT CAMP GEIGER.

IDENTIFY PROJECT INVOLVEMENT
THIS PROJECT IS A PART OF THE NEW RIVER BASIN, AND IS CURRENTLY NOT
SUBJECT TO ANY BUFFER RULES. THE SITE IS APPROXIMATELY 3600 FEET FROM THE
NEW / WHITE OAK RIVER, JUST OUTSIDE OF JACKSONVILLE, NC AND IS LOCATED IN
ONSLOW COUNTY, WHICH IS A PHASE II - NPDES REQUIREMENT COUNTY.
THE PROPOSED PROJECT STORMWATER PLAN WILL MEET THE REQUIREMENTS
OF DETAINING THE 1.5 INCH RAINFALL EVENT FOR A PERIOD OF APPROXIMATELY 5
DAYS, PER THE 85% REMOVAL REQUIREMENT FOR TSS. THE WET DETENTION BASIN
WILL PROVIDE NUTRIENT REMOVAL FOR TN AND TP, THOUGH IT IS NOT REQUIRED FOR
THIS PERMIT. ADDITIONALLY, THE BASIN DESIGN, OUTLET STRUCTURE AND THE USE
OF GRASSED SWALES WILL PROVIDE A POST DEVELOPMENT PEAK FLOW RATE THAT IS
LESS THAN THE EXISTING CONDITION, PER THE JULY 2007 START DATE FOR MEETING
PHASE II REQUIREMENTS.
STORMWATER DESIGN PARAMETERS
THE MODIFICATIONS TO THE EXISTING DETENTION BASIN ARE BASED ON THE
FOLLOWING PARAMETERS OR OBJECTIVES:
• PROVIDE 85% TSS REMOVAL
• PROTECT THE VALUE OF THE RECEIVING WATER RESOURCE
• 1,5" RAINFALL FOR TEMPORARY BASIN STORAGE SIZING
• THE 1 YR RAINFALL FOR OUTLET STRUCTURE AND ROUTING DESIGN TO
MAINTAIN A POST DEVELOPMENT PEAK FLOW THAT IS LESS THAN PRE -
DEVELOPMENT PEAK FLOW
• RATIO OF IMPERVIOUS SURFACE TO THE TOTAL AREA OF THE DRAINAGE AREA
• FLOW LENGTH RATIO TO PROVIDE INTENDED TSS REMOVAL

DISCUSSION OF TREATMENT MEASURES
THE PROPOSED TREATMENT IS TO CONSTRUCT AN ADDITIONAL BASIN AND
REMOVE 1.9 ACRES OF THE PROJECT SITE FROM THE II.1 ACRES OF THE
CONTRIBUTING DRAINAGE AREA OF THE CURRENTLY PERMITTED BASIN. AS THE
REQUIREMENTS OF DWQ ARE MORE STRINGENT TODAY THAN THEY WERE WHEN THE
EXISTING BASIN WAS PERMITTED, RETROFITTING THE EXISTING BASIN IS IMPRACTICAL
AND UNFEASIBLE DUE TO SITE CONSTRAINTS. FURTHERMORE, THE EXISTING BASIN IS
FULLY FUNCTIONAL AND WELL ESTABLISHED. THE PROPOSED BASIN WILL REDUCE
THE RUNOFF THAT THE EXISTING BASIN IS RECEIVING AND FURTHER AUGMENT THE
FUNCTION OF THE EXISTING BASIN.
THE PROPOSED BASIN MEETS ALL OF THE FUNDAMENTAL REQUIREMENTS OF
DESIGN CONFIGURATION THAT ARE DEFINED BY DWQ. THE ATTACHED SUPPLEMENT
FORM, CALCULATION SHEETS AND DESIGN PLANS INDICATE HOW THESE
REQUIREMENTS MEET MINIMUM SPECIFICATION FOR:
• MINIMUM REQUIRED STORAGE VOLUME FOR THE 1.5" RAIN EVENT
• MINIMUM AVERAGE DEPTH OF 3' ABOVE SEDIMENT REMOVAL ELEVATION
• MINIMUM SA/DA RATIO
• FOREBAY GEOMETRY AND VOLUME
• FLOW LENGTH RATIO
• LENGTH TO WIDTH RATIO
• DISCHARGE ENERGY DISSIPATION AND 30' VEGETATED FILTER STRIP
• VEGETATIVE SHELF GEOMETRY
• MAINTENANCE ACCESS
• SEDIMENT REMOVAL
• OUTLET CONFIGURATION AND TRASH RACK
PHASE II REQUIREMENTS ARE MET BY USING ADEQUATE BASIN GEOMETRY,
OUTLET CONFIGURATION AND A GRASSED SWALE TO REDUCE PEAK FLOWS FOR THE 1
YR. 24 HR STORM. A 1.5 INCH ORIFICE YIELDS AN ESTIMATED DRAW DOWN TIME OF 5
DAYS AND PROVIDES A MAXIMUM AMOUNT OF TIME FOR INFILTRATION TO
GROUNDWATER AND TREATMENT OF TSS AND NUTRIENTS. THE PROPOSED OUTLET,
ROUTING AND BASIN DESIGN WILL HAVE A PEAK OUTLET FLOW RATE OF
APPROXIMATELY 0.41 CFS AT APPROXIMATELY 13 HOURS, WHICH HIS LESS THE PRE -
DEVELOPMENT FLOW RATE OF 1.04 CFS. (HYDROCAD MODEL RESULTS ARE ATTACHED)
CONCLUSION
THIS STORMWATER MANAGEMENT PLAN REPRESENTS AN ENVIRONMENTALLY
SENSITIVE AND EFFECTIVE PLAN FOR UTILIZING THE STORMWATER TREATMENTS TO
ACCOMMODATE THE INCREASED RUNOFF OF THE PROPOSED SITE DEVELOPMENT.
