Dear Mr. Bean:
Dee Freeman
Secretary
The Stormwater Permitting Unit received a complete Stormwater Management Permit Application for Fort
Bragg — 1081h ADA Brigade Complex on January 24, 2011. 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 2006-246. We are forwarding Permit No. SW6101106, dated
February 4, 2011, for the construction, operation and maintenance of the subject project and the
stormwater BMPs.
This permit shall be effective from the date of issuance until February 3, 2021, 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 inspection 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 adiudicatory hearina upon written recluest within thirty (30) 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 Administrative Hearings, P.O. Drawer 27447, Raleigh, NC
27611-7447. Unless such demands are made this permit shall be final and binding.
This project will be kept on file at the Fayetteville Regional Office. If you have any questions, or need
additional information concerning this matter, please contact Brian Lowther at [phone]; or
[e-mail].
Sincerely,

' F%.' PROJECT INFORMATION
1. In the space provided below, briefly summarize how the stormwater runoff will be treated.
Stormwater will be collected -via piping nehvorks that will discharge into the Wet Detention Ponds The Wet
Detention Ponds are sized to remove 90'/ TSS for the Coastal region. In addition, the Wet Detention Basins
will treat the difference between the pre -construction and ost-construction flows for the 1-year and 2-year
storm event to meet LEEDs requirements.
2. a. If claiming vested rights, identify the supporting documents provided and the date they were approved:

Wet 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 wet detention basin system is defined as the wet detention basin,
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:
— Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
— No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
— Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
— If the basin must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain should be minimized to the
maximum extent practical.
— Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month 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 should be kept in a known set
location and must be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

Wet 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 wet detention basin system is defined as the wet detention basin,
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:
— Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
— No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
— Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
— If the basin must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain should be minimized to the
maximum extent practical.
— Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month 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 should be kept in a known set
location and must be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

Average Depth
Depth of Pond = 3.5 It Depth (dist. btwn. bot. of shelf 8 btm. of pond, excludes sediment)
Average Depth = 3.14 ft
Use Average Depth of = 3.00 ft Round down to nearest 0.5
Required Surface Area - Wetland
SA/DA = 2.39 (90% TSS Removal via Pond)
Min Req'd Surface Area = 48,640 sf (at Permanent Pool)
Required Storage Volume - Using Simple Method
Design Storm = 1 inch (Project Does Not Drain to SA waters)
Determine Rv Value = 0.05 + 0.009 (1) = 0.39 in/in
Storage Volume Required = 66,861 cf (above Permanent Pool)
Side Slopes of Pond = 3 :1
Is Permenant Pool Surface Area Sufficient (yes/no)? Yes ( 90980 > 48640 ) sf
