State Stormwater Management Permit No. SW8 080202

Dear Mr. Wileman:
Effective August 1, 2013 the State Stormwater program has been transferred from the Division of Water Quality
(DWQ) to the Division of Energy, Mineral and Land Resources (DEMLR). All previous references to DWQ will
remain in older stormwater 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 issuance 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
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 June 2, 2021. The Division is hereby notifying you that permit SW8 080202 has been renewed on
June 16, 2021, and shall be effective until December 30, 2029, 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 terms; 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 February 6, 2008 will remain in
full force and effect in accordance with the regulations set forth in Title 15A 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 I50B 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.

Sand Filter 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.
Important maintenance procedures:
— The drainage area will be carefully managed to reduce the sediment load to the
sand filter.
— Once a year, sand media will be skimmed.
— The sand filter media will be replaced whenever it fails to function properly after
vacuuming.
The sand filter will be inspected quarterly 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 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.
