Subject: State Stormwater Management Permit No. SW8 960117
French Creek WWTP Improvements
High Density Commercial Project
Onslow County
Dear Mr. Baker
Natural Resources
Dee Freeman
Secretary
The Wilmington Regional Office received a complete Stormwater Management Permit Application for French Creek
WWTP Improvements on August 17, 2012. This modification included the demolition and removal of an existing access
road and the construction of several buildings along with accompanying drives, parking, and sidewalk access resulting in a
net increase of 19,080 square feet of impervious surface. These modifications eliminated drainage area "Alternate" (the
road drainage area), modified drainage area "A", and left drainage area "B" unchanged. 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 960117 dated August 17, 2012, for the construction of the
subject project.
On August 5, 2009, the Governor signed Session Law 2009-406, This law impacts any development approval issued by
the Division of Water Qualityy under Article 21 of Chapter 143 of the General Statutes, which is current and valid at any
point between January 1, 2008, and December 31, 2010. The law extends the effective period of any stormwater PPermit
that was set to expire during this time frame up to three (3) years from its current expiration date. On August 2, 2010, the
Governor signed Session Law 2010-177, which granted an extra year for an extension of up to four (4) years.
This permit shall be effective from the date of issuance until February 19, 2022, which includes all available extensions,
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, certification
of the BMP's, procedures for changes of ownership, transferring the permit, and renewing the permit. Failure to establish
an adequate s stem for operation and maintenance of the stormwater management system, to record deed restrictions, to
certify the BMA, to transfer the permit, or to renew the permit, 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 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 contact the OAH with all questions regarding the filing fee (if a filing fee is required)
and/or the 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

IV. PROJECT INFORMATION
1. In the space provided below, briefly summarize how the stormwater runoff will be treated.
Additional Stormwater from construction of the French Creek W WTP Improvements will be routed via a
combination of yard inlet/pipes, and grassed swales from impervious areas to the existing stormwater wet -
detention basin, "Pond A". The wet -detention basin was permitted with enough additional capacity to treat
the minimum required volume from the 1 5" storm associated with the new impervious area This project is
not located within 1/2 mile of SA waters or within 575 ft of ORW waters.
2. a. If claiming vested rights, identify the supporting documents provided and the date they were approved:
❑ Approval of a Site Specific Development Plan or PUD Approval Date:

6. Total Surface Water Area: 0 acres
7. Total Property Area (4) - Total Coastal Wetlands Area (5) - Total Surface Water Area (6) = Total Project
Area':20.1 acres
Total project area shall be calculated to exclude the following: the normal pool of impounded structures, the area
between the banks of streams and rivers, the area below the Normal High Water (NHW) line or Mean High Water
(MHW) line, and coastal wetlands landward from the NHW (or MHI) line. The resultant project area is used to
calculate overall percent built upon area (BUA). Non -coastal wetlands landward of the NHW (or MHW) line may
be included in the total project area.
8. Project percent of impervious area: (Total Impervious Area / Total Project Area) X 100 = 23.03
9. How many drainage areas does the project have?2 (For high density, count 1 for each proposed engineered
stormwater BMP. For low density and other projects, use 1 for the whole property area)

Project Description
This document is to serve as a modification to an existing permit (SW8 960117)
for the USMCB Camp Lejeune — French Creek Waste Water Treatment Plant
Improvements Project (FC WWTP). The proposed FC WWTP is located near French
Creek Area of Marine Corps Base Camp Lejeune in Onslow County, North Carolina.
The proposed project involves the demolition of an existing access road and the
construction of multiple improvements to the FC WWTP including a new head works,
equalization basin, blower building, pump station, generator pad and an associated
access road on the Northwest portion of the site. The project limits are currently
comprised of grassed areas within the FC WWTP.

Identify Project Involvement
The proposed project is located in the White Oak River Basin. The project drains
to French's Creek (NCDWQ Index Number 19-24), which has an NCDWQ Stream
Classification of SC, NSW.
The FC WWTP Improvements project includes the demolition of an existing
access road that is approximately 11,564 sf of existing impervious area and the
construction of approximately 21,022 sf of impervious, resulting in a net increase in BUA
of approximately 9,458 sf. The proposed project stormwater management will meet the
requirements of retaining the runoff volume from the 1.5 inch rainfall event per the
requirements by the state as referenced from the DWQ Stormwater Manual, July 2007.
Approximately 17,667 sf of the proposed impervious area will be captured and treated
via extra capacity provided in Stormwater "Pond A" of the existing Stormwater Permit
Number: SW8 960117. The two stormwater ponds are currently being used to treat two
drainage areas and were originally designed with excess capacity to allow for future
development. This project is not within 1/2 miles of SA waters, or 575 feet of ORW
waters.
Stormwater Design Parameters
The existing stormwater ponds were designed in accordance with the state
stormwater regulations in 1996. These requirements differ from today's requirements, as
only the first 1" had to be treated. However, in a scoping meeting held with DWQ it was
stated that the ponds do not have to be redesigned to meet current stormwater
RE CEIVED
AUG 1 5 2012
BY:

regulations if they have enough capacity to treat the 1.5" design storm from the increase
in BUA associated with the proposed project.
Discussion of Treatment Measures
The existing permitted treatment utilizes the two existing permitted stormwater
ponds to treat the required volume from the 1" design storm and meet the TSS and Peak
Flow requirements set forth by DWQ.
This modification is addressing the adjustments due to the increase in drainage
area and amount of impervious area for the associated stormwater "Pond A".
Specifically, to insure that the existing stormwater pond has enough additional capacity
to account for the additional runoff from these proposed improvements. According to
Stormwater Permit Number SW8 960117, Pond A has enough additional permitted
capacity to treat the 1.5" rainfall depth runoff volume for the proposed improvements.
See table below for a breakdown of volumes and capacity:

Subject: Stormwater Permit No. SW8 960117 Renewal
French's Creek Waste Water Treatment Plant
High Density Project
Onslow County
Dear Mr. Baker:
The Wilmington Regional Office received a complete Stormwater Management Permit
Application for French's Creek Waste Water Treatment Plant on September 19, 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 960117 dated February 19, 2008, for the construction and
operation of the subject project.
This permit shall be effective from the date of issuance until February 19, 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.
The reissuance of this stormwater permit does not imply that the site is currently in compliance
with the terms and conditions of this state stormwater permit.
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 David Cox, or me at [phone].

Project Description
This document is to serve as a modification to an existing permit (SW8 960117)
for the USMCB Camp Lejeune — French Creek Waste Water Treatment Plant
Improvements Project (FC WWTP). The proposed FC WWTP is located near French
Creek Area of Marine Corps Base Camp Lejeune in Onslow County, North Carolina.
The proposed project involves the demolition of an existing access road and the
construction of multiple improvements to the FC WWTP including a new head works,
equalization basin, blower building, pump station, generator pad and an associated
access road on the Northwest portion of the site. The project limits are currently
comprised of grassed areas within the FC WWTP.

Identify Project Involvement
The proposed project is located in the White Oak River Basin. The project drains
to French's Creek (NCDWQ Index Number 19-24), which has an NCDWQ Stream
Classification of SC, NSW.
The FC WWTP Improvements project includes the demolition of an existing
access road that is approximately 11,564 sf of existing impervious area and the
construction of approximately 21,022 sf of impervious, resulting in a net increase in BUA
of approximately 9,458 sf. The proposed project stormwater management will meet the
requirements of retaining the runoff volume from the 1.5 inch rainfall event per the
requirements by the state as referenced from the DWQ Stormwater Manual, July 2007.
Approximately 17,667 sf of the proposed impervious area will be captured and treated
via extra capacity provided in Stormwater "Pond A" of the existing Stormwater Permit
Number: SW8 960117. The two stormwater ponds are currently being used to treat two
drainage areas and were originally designed with excess capacity to allow for future
development. This project is not within 1/2 miles of SA waters, or 575 feet of ORW
waters.
Stormwater Design Parameters
The existing stormwater ponds were designed in accordance with the state
stormwater regulations in 1996. These requirements differ from today's requirements, as
only the first 1" had to be treated. However, in a scoping meeting held with DWQ it was
stated that the ponds do not have to be redesigned to meet current stormwater
RECEIVED
AUG 1 5 Z012
BY:

regulations if they have enough capacity to treat the 1.5" design storm from the increase
in BUA associated with the proposed project.
Discussion of Treatment Measures
The existing permitted treatment utilizes the two existing permitted stormwater
ponds to treat the required volume from the 1" design storm and meet the TSS and Peak
Flow requirements set forth by DWQ.
This modification is addressing the adjustments due to the increase in drainage
area and amount of impervious area for the associated stormwater "Pond A".
Specifically, to insure that the existing stormwater pond has enough additional capacity
to account for the additional runoff from these proposed improvements. According to
Stormwater Permit Number SW8 960117, Pond A has enough additional permitted
capacity to treat the 1.5" rainfall depth runoff volume for the proposed improvements.

Project Description
This document is to serve as a modification to an existing permit (SW8 960117)
for the USMCB Camp Lejeune — French Creek Waste Water Treatment Plant
Improvements Project (FC WWTP). The proposed FC WWTP is located near French
Creek Area of Marine Corps Base Camp Lejeune in Onslow County, North Carolina.
The proposed project involves the demolition of an existing access road and the
construction of multiple improvements to the FC WWTP including a new head works,
equalization basin, blower building, pump station, generator pad and an associated
access road on the Northwest portion of the site. The project limits are currently
comprised of grassed areas within the FC WWTP.

Identify Project Involvement
The proposed project is located in the White Oak River Basin. The project drains
to French's Creek (NCDWQ Index Number 19-24), which has an NCDWQ Stream
Classification of SC, NSW.
The FC WWTP Improvements project includes the demolition of an existing
access road that is approximately 11,564 sf of existing impervious area and the
construction of approximately 21,022 sf of impervious, resulting in a net increase in BUA
of approximately 9,458 sf. The proposed project stormwater management will meet the
requirements of retaining the runoff volume from the 1.5 inch rainfall event per the
requirements by the state as referenced from the DWQ Stormwater Manual, July 2007.
Approximately 17,667 sf of the proposed impervious area will be captured and treated
via extra capacity provided in Stormwater "Pond A" of the existing Stormwater Permit
Number: SW8 960117. The two stormwater ponds are currently being used to treat two
drainage areas and were originally designed with excess capacity to allow for future
development. This project is not within 1/2 miles of SA waters, or 575 feet of ORW
waters.
Stormwater Desictn Parameters
The existing stormwater ponds were designed in accordance with the state
stormwater regulations in 1996. These requirements differ from today's requirements, as
only the first 1" had to be treated. However, in a scoping meeting held with DWQ it was
stated that the ponds do not have to be redesigned to meet current stormwater
EFCETVED
AUG u 5 2012
BY:.

regulations if they have enough capacity to treat the 1.5" design storm from the increase
in BUA associated with the proposed project.
Discussion of Treatment Measures
The existing permitted treatment utilizes the two existing permitted stormwater
ponds to treat the required volume from the 1" design storm and meet the TSS and Peak
Flow requirements set forth by DWQ.
This modification is addressing the adjustments due to the increase in drainage
area and amount of impervious area for the associated stormwater "Pond A".
Specifically, to insure that the existing stormwater pond has enough additional capacity
to account for the additional runoff from these proposed improvements. According to
Stormwater Permit Number SW8 960117, Pond A has enough additional permitted
capacity to treat the 1.5 rainfall depth runoff volume for the proposed improvements.
See table below for a breakdown of volumes and capacity:

Conclusion
This Stormwater Management Plan represents an environmentally sensitive and
effective plan for utilizing the proposed stormwater treatments to accommodate the
increased runoff of the proposed site development.

Express Review Fee - Modification
Linda,
I am planning on submitting a high density stormwater permit modification for the French Creek Waste Water
Treatment Plant on MCB Camp Lejeune next week and 1 had a question in regards to the permit fee. We had a scoping
meeting with you for this project over a year ago but it was put on hold until recently. Essentially they are proposing
some improvements consisting of a headwork's facility and an open equalization basin and runoff from the new
impervious surfaces are being captured and routed to the existing permitted stormwater "Pond A" which was built with
enough extra capacity to handle the required treatment volume from the 1.5" rainfall on the new impervious surfaces.
Per our scoping meeting the pond will not be modified since it has enough capacity so we are really just routing more
drainage area and impervious area to the pond. Previously I have been told that as long as the BMP is not being
modified then it is a minor modification. My question is to just clarify if this needs to be a minor modification fee of
$2,000 or a major modification of $4,000?
Please let me know as soon as you can as I need to submit the check request by 2PM today in order to get the check in
time. Thank you in advance for your response!
