Subject. Permit Renewal
State Stormwater Management Permit No. SW8 970233
Sunset Beach Mini Storage
Brunswick County
Dear Mr. Lampe:
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
stormwater 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 Wilmington Regional Office received a complete 8 year Stormwater Management Permit Renewal Application for
the subject project on September 7, 2021. The Division is hereby notifying you that permit SW8 970233 has been
renewed on September 27, 2021, and shall be effective until April 6, 2028, which includes all available extensions.
For your records, please find enclosed a renewed, updated, and re -issued permit and a copy of the renewal application.
Please keep this permit on file at all times. Please note that the renewed, updated, and re -issued permit does not impose
new or different temis; it merely restates some of the previous terms to provide you with a better understanding of your
obligations under the permit.
The renewal and 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. The plans originally approved on April 6, 1998 and most recently
modified on March 2, 2016, will remain in full force and effect in accordance with the regulations set forth in Title i SA
NCAC 2H.1000.
This permit is 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, procedures for changes of ownership, transferring the permit, and renewing the permit. Failure to establish
an adequate system for operation and maintenance of the stormwater management system, to record deed restrictions,
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.
If you have any questions, need additional copies of the permit or approved plans, please contact Ashley Smith in the
Wilmington Regional Office, at (910) 796-7215 or ashleym.smith@ncdenr.gov.

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 VE
within 24 hours after every storm event greater than 1.0 inches (or 1.5 h r in a
Coastal County). Records of operation and maintenance should be ke a wnisoft
location and must be available upon request. BY:_

Stormwater Wetland 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.
Important maintenance procedures:
— Immediately following construction of the stormwater wetland, bi-weekly inspections will be
conducted and wetland plants will be watered bi-weekly until vegetation becomes established
(commonly six weeks).
— No portion of the stormwater wetland will be fertilized after the first initial fertilization that is
required to establish the wetland plants.
— Stable groundcover will be maintained in the drainage area to reduce the sediment load to the
wetland.
— Once a year, a dam safety expert should inspect the embankment.
After the stormwater wetland is established, I will inspect it monthly 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.
