Post -Construction Stormwater Management Permit No. SW8%0614
Leland Industrial Park Lot 58
Brunswick County
Dear Ms. Joyce:
Effective August 1, 2013 the Post -Construction Stormwater Management Program has been transferred from the
Division of Water Quality ("DWQ") to the Division of Energy, Mineral and Land Resources ("DEMLIV ). All
previous references to DWQ will remain in older permits issued prior to August 1, 2013 until they are modified.
Please note that this permit will now reference DEMLR as the Division responsible for enforcement of the permit.
On August 5, 2009, the Governor signed Session Law 2009-406. This law impacted any development approval
issued by the former Division of Water Quality under Article 21 of Chapter 143 of the General Statutes, which
was current and valid at any point between January 1, 2008, and December 31, 2010. The law extended the
effective period of any permit that was set to expire during this time frame 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
a total of four (4) years extension.
The Division of Energy, Mineral and Land Resources received a complete 8-year Permit Renewal Application for
the subject permit on December 211, 2022. The Division is hereby notifying you that permit SW8960614 has
been renewed, updated, and re -issued on January 5`s, 2023, as attached. As requested, a copy of the current
operation and maintenance agreement is also enclosed. Please be aware that the renewal and re -issuance of this
stormwater permit does not imply that the site is currently in compliance.
This permit shall be effective until September 51, 2030, which includes all available extensions, and does not
supersede any other agency permit that may be required. The project shall be subject to the conditions and
limitations as specified therein. This permit does not impose new or increased stormwater control requirements; it
clarifies the rules and requirements of this program to provide you with a better understanding of your obligations
under this permit. Failure to comply with these requirements will result in future compliance problems. Please
note that this permit is not transferable except after notice to and approval by the Division.
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.
If you have any questions concerning this permit, please contact Aisia Freeman in the Wilmington Regional
Office, at phone # [phone] or [e-mail].

Wet Detention Basin Inspection 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.

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 inspection 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
