Dear Mr. Baker:
Coleen H. Sullins, Director
Division of Water Qua]iq'
The Wilmington Regional Office received a complete, modified Stormwater Management
Permit Application for Courthouse Bay Regional Pond on August 28, 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 030720 Modification dated August 28, 2007, for the construction of the subject project.
This modification will cover the addition of P-1030, Enlisted Dining Facility to the project area.
This permit shall be effective from the date of issuance until January 26, 2015, 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
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

Date: Tue, 28 Aug 2007 08:41:09 -0400
To: Stephen Thomas <[e-mail]>, Nick Lauretta <[e-mail]>
Steve:
The revised forebay calculation is incorrect. The forebay volume is based on 20% of
the permanent pool volume, which is the volume provided in the pond from the bottom
to the permanent pool elevation. The latest sealed calculations appear to conclude
that the permanent pool volume is 368,006. This is not correct. Based on
interpolating the numbers provided in the revised calculations, the permanent pool
volume at elevation 7.38 is only 193,648, as reported on the supplement, meaning
that the maximum range of forebay volumes is 34,857 to 42,603 (.18 and .22 times
193,648).
The supplement and calculations report 71,303 as the provided volume, however, this
number appears to be what is provided at elevation 9.92, well above the permanent
pool elevation. Please revise the forebay calculations such that the permanent pool
volume is correctly reported as 193,648 and the calculation of the required forebay
volume (from the bottom of the forebay to elevation 7.38) is based on that number
and the provided forebay volume is within the range stated above.
Please submit revised forebay sizing calculations (sealed, signed & dated).

Steve:
This is my fault- Rhonda had asked me about how to handle the project, and I made
my comments back to her, but then she wanted me to do the review. I either didn't
realize it was an Express project, or I forgot it was Express. I've already got a
meeting scheduled for this afternoon, but if I get the chance, I'll get the full
review done after my meeting.
Preliminarily, there appears to be some confusion about whether this project is a
modification, plan revision or offsite. Based on my review of the existing
Courthouse Bay file, the dining facility appears to be located within the permitted
drainage area, but because the street names are not consistent, I can't be sure. If
it is within the DA, then it will be an Offsite project, not a modification. The
Dining Facility will receive its own permit. If it comes out that the Dining
Facility is not within the existing approved DA for Courthouse Bay Regional pond,
then in addition to the offsite permit for the Dining Facility, a modification to
the Courthouse Bay pond permit is also needed.

STORMWATER IMPACT ANALYSIS
CAMP LE]EUNE ENLISTED DINING FACILITY (P1030)
CAMP LE]UENE, NORTH CAROLINA
EXECUTIVE SUMMARY
This Stormwater Impact Analysis has been prepared specifically to address
the requirements of Section 15A NCAC 02H .1005 of the North Carolina
Administrative Code as it pertains to the stormwater requirements for coastal
counties. The project site does not drain to Outstanding Resource Waters nor is it
within one-half mile of SA waters or unnamed tributaries of SA water. Therefore,
stormwater management must be in accordance with Rule .1005 (3).
Site Information
The Camp Lejeune Enlisted Dining Facility is located at the southwest corner
of Jackson Street and Horn Road in Camp Lejeune, North Carolina. The site lies
within the White Oak River Basin and is outside of any stream buffers, floodpiains,
wetlands, and Water Supply Watersheds. The project site sits in a relatively flat
area and entirely drains to the existing stormwater management pond, which will
be utilized to meet water quality and quantity regulations.
One permitted water quality device currently exists within the drainage area
for stormwater treatment, which is a wet detention pond (NCDENR, DWQ Permit
#SW8 030720). In order to drain this project's built -upon -area to the existing
pond, existing permit SW8 030720 will be modified to include treatment required
for the proposed Dining Facility.
Proposed Improvements
The project proposes to add one new building; the Dining Facility building.
This project also proposes to construct a large parking area having 160 spaces, a
service entry/loading dock area, and multiple sidewalks. In order to construct the
new Dining Facility, an existing concrete storage area and concrete drainage swale
will be demolished. The site has a total area of 4.76 ac of which 2.52 ac is
proposed built -upon -area. The total Courthouse Bay Regional Pond drainage area
will increase from 45.81 ac to 50.57 ac due to piped stormwater conveyed to the
pond. The project proposes a net increase of 2.52 ac of impervious bring the
proposed total impervious area, within the regional pond drainage area, to 17.50 ac
(34.6%).
The improvements proposed for the existing Courthouse Bay Regional Pond
stormwater facility include the expansion of the wet detention pond and forebay.
The proposed expansion of the existing regional facility will be used to meet water
quality regulations set forth by the State.

Design Requirements
Per Section 15A NCAC 02H .1005 (3) of the North Carolina Administrative
Code for sites that are not with 575 ft of Outstanding Resource Water or within 0.5
miles of SA waters the State Stormwater Regulations mandate that the runoff from
the first one (1) inch of rainfall be captured and released over a period of 2 to 5
days. The treatment device proposed is the expansion of the existing Courthouse
Bay Regional Facility. The existing wet pond provides a bypass as well as a
vegetated buffer, requiring the treatment and release over a period of 2 to 5 days
of the first inch of rainfall.
Design Procedure
Per State Stormwater Management Systems Permit Number SW8 030720,
the existing Courthouse Bay Regional Pond was planned to provide water quality
treatment for future phased development within the drainage area. The proposed
expansion of the existing wet pond falls well under the entire pond design criteria.
Four exhibit maps accompany this report to provide additional information.
Exhibit EX-1 shows the existing conditions of the site along with the impervious
surface that will be removed. Exhibit EX-2 shows the proposed conditions of the
site. Exhibit EX-3 shows typical dimensions of existing and proposed impervious
area within the drainage basin. Exhibit EX-4 shows the existing site with the
proposed basin expansion overlaid.
The pond expansion has been sized to capture the runoff from the first one
(1) inch of rainfall for its entire drainage area. The existing pond provides a bypass
and grassed Swale for overflow; therefore it has only been sized for the first one (1)
inch.
Overall Results / Summary
Table 1 below shows the statistics for the proposed regional pond expansion. The
proposed pond expansion achieves the required storage volume, therefore
treatment credit is assumed for the entire drainage area.

Conclusions
Based on the results of this Stormwater Impact Analysis, the requirements of
Section 15A NCAC 02H .1005 of the North Carolina Administrative Code as it
pertains to the stormwater requirements for coastal counties have been met for the
proposed project. Runoff from all new impervious area has been captured and
treated in the existing regional pond.

Footnotes:
When using the Division SAIDA tables, the correct SA/DA ratio for permanent pool sizing should be computed based upon the
actual impervious % and permanent pool depth. Linear interpolation should be employed to determine the correct value for non-
standard table entries.
2 In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90% TSS removal. The NCDENR BMP manual provides design tables for both 85% TSS removal and 96% TSS removal.
II. REQUIRED ITEMS CHECKLIST

This system (check one) /does 0 does not incorporate pretreatment other than a forebay.
Form S W U-102 Rev 3.99 Page 2 of 4

Maintenance activities shall be performed as follows:
1. After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within
2 to 5 days as designed.
2. Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed.
3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to maintain
proper functioning.
4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is
reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed of
in an appropriate manner and shall be handled in a manner that will not adversely impact water quality (i.e.
stockpiling near a wet detention basin or stream, etc.).
The measuring device used to determine the sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.
When the permanent pool depth reads 3 feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads 3 feet in the forebay, the sediment shall be removed.

CC: Cameron Weaver <[e-mail]>
Steve:
Thanks for letting me know. I do remember discussing that now and it's making more
sense to me. I think when we were talking about it earlier, the proposed dining
facility project was presented to me as NOT being within the approved drainage area of
the pond, thus my comments that a modification was needed. I think that the way the
original pond was intended to be permitted and modified was with an established maximum
drainage area of 77.85 acres that was flexible in its location, depending on what the
Base needed. Each separate.new proposed project, either already within the DA, or
wanting to be in the DA, would require a permit modification to establish the new DA
boundary and tally up the total BUA to date.
So, in light of that, please address the following inconsistencies in the application:
1. Provide a new map delineating the 50.574 acre drainage area.
2. The calculations use a permanent pool surface area of 62,870 (interpolated) but
64,930 has been reported on the supplement. The numbers must match up.
3. The temporary pool volume reported on the application is only 68,266. The value to
report should be the actual volume stored in the pond between the designated permanent
pool and temporary pool elevations. Based on the surface areas and accumulated volumes
reported in your calculations, between 7.38 and 8.92, there would be over 102,000 cubic
feet of volume provided. ((62,870 + 70,091)/2) x (8.92 - 7.36) = 102,380 cubic feet.
4. The calculations show area and volume tables which are based on a bottom elevation
of 3.92, but the actual bottom elevation for the pond is 3.38. This appears to affect
the calculation of the permanent pool volume. Based on interpolating the values
reported in the tables, the permanent pool volume is 177,443 cubic feet.:Please provide
verification of how you arrived at 181,851.
Please submit the requested information by close of business August 17, 2007.

review. I either didn't realize it was an Express project, or I forgot
it was Express. I've already got a meeting scheduled for this
afternoon,
but if I get the chance, I'll get the full review done after my
meeting.
Preliminarily, there appears to be some confusion about whether this
project is a modification, plan revision or offsite. Based on my
review
of the existing Courthouse Bay file, the dining facility appears to be
located within the permitted drainage area, but because the street
names
are not consistent, I can't be sure. If it is within the DA, then it
will be an Offsite project, not a modification. The Dining Facility
will
receive its own permit. If it comes out that the Dining Facility is
not
within the existing approved DA for Courthouse Bay Regional pond, then
in addition to the offsite permit for the Dining Facility, a
modification to the Courthouse Bay pond permit is also needed.

I think I may have been wrong in regard to needing a separate offsite
permit & modification to 030720 for this project. In the non-military
world, that would be the case, but because this is the Base, and the
same people are going to own the pond AND the projects that drain to
it, only a modification to 030720 is required.
I'll get this scheduled ASAP.

Linda,
I have few details I would like to clarify concerning the Camp Lejeune
Permit:
1. The existing permit (DWQ Permit #SW8 030720) was permitted for the
entire build out of the drainage area including the construction of
P-1030.
2. A permit modification (DWQ Permit # SW8 041104) was granted on
January 26, 2005 to build a smaller pond due to monetary constraints
with the idea that future development within the drainage area would
require an expansion of the pond not to exceed the original permit (DWQ
Permit # SW8 030720) specifications.
Question:
Does the current pond expansion require a revision to the DWQ permit;
even if the current expansion is still less than original permit
specifications?
If a permit modification is required, will it be a modification to the
original permit (DWQ Permit #SW8 030720) or the permit modification (DWQ
Permit #SW8 041104)?
Attached is a summary sheet from the permit modification.
Thanks,
Nick Lauretta

Nick,
Please email with Linda to clarify which reviews will be necessary for
the project. It is my understanding that only a modification to the
existing stormwater permit will be required, as the project site drains
(in its entirety) to the existing pond, and we are increasing the total
built -upon area which drains to the pond to a level higher than the
original permit accounted for (please confirm this with Linda).
Linda,
Nick is an engineer with 2.5 years experience in Virginia that recently
joined our staff here in Wilmington. He has performed the design and
applications (under my supervision) for the project.
Thanks,
Steve
