Subject: Stormwater Management Permit No, SW8120408
GOGAS #20
High Density Commercial infiltration Basin Project
Brunswick County
Dear Mr. Austin:
Dee Freeman
Secretary
The Wilmington Regional Office received a complete State Stormwater Management Permit Application for GOGAS
#20 on June 4, 2012. Staff review of the plans and specifications has determined that the project, as proposed, will
comply with the Stormwater Regulations set forth in Session Law 2008-211 and Title 15A NCAC 2H.1000. We are
forwarding Permit No. SW8120408 dated June 4, 2012, for the construction, operation and maintenance of the
BMP's and built -upon area associated with the subject project.
This permit shall be effective from the date of issuance until June 4, 2020, 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 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 fled with the OAH within thirty
(30) days of receipt of this permit. You should contact the OAH with all questions regarding the fling 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.
If you have any questions, or need additional information concerning this matter, please contact Kelly Johnson, at
[phone].
Sincerely,

2008-211 and 15A NCAC 2H .1000 (hereafter collectively and separately referred to as the "stormwater rules') and
the approved stormwater management plans and specifications and other supporting data as attached and on file
with and approved by the Division of Water Quality and considered a part of this permit.
This permit shall be effective from the date of issuance until June 4, 2020, and shall be subject to the following
specified conditions and limitations:
I. DESIGN STANDARDS
This permit is effective only with respect to the nature and volume of stormwater described in the application
and other supporting data.
2. This stormwater system has been approved for the management of stormwater runoff as described in
Section 1.8 on page 3 of this permit. The stormwater control has been designed to handle the runoff from
49,424 square feet of impervious area. The infiltration basin has not been designed to accommodate future
impervious area beyond 49,424 square feet.
3. This basin has been designed to infiltrate the 1 Qyear 24hour storm event at half the reported infiltration rate
without discharge. Therefore no bypass or vegetated filter strip are required.
The tract will be limited to the amount of built -upon area indicated in Section 1.8 on page 3 of this permit,
and as shown on the approved plans.
All stormwater collection and treatment systems must be located in either dedicated common areas or
recorded easements. The final plats for the project will be recorded showing all such required easements, in
accordance with the approved plans.
The runoff from all built -upon area within the permitted drainage area of this project must be directed into
the permitted stormwater control system.

and perpendicular to the normal pool of impounded structures, the top of bank of both sides of streams and
rivers, and the mean high water line of tidal waters.

Infiltration Basin Operation and Maintenance Agreement /Vlow/ob
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.
Important maintenance procedures:
The drainage area will be carefully managed to reduce the sediment load to the
infiltration basin.
- Immediately after the infiltration basin is established, the vegetation will be
watered twice weekly if needed until the plants become established (commonly
six weeks).
— No portion of the infiltration basin will be fertilized after the initial fertilization
that is required to establish the vegetation.
— The vegetation in and around the basin will be maintained at a height of
approximately six inches.
After the infiltration basin is established, it will be inspected once a quarter 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 will be kept in a known set location
and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.
