Subject: Permit Renewal
State Stormwater Management Permit No. SW8 090632

Onslows County
Dear Mr. Paul:
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.
The Wilmington Regional Office received a complete 8 year Stormwater Management Permit Renewal Application for
the subject project on May 17, 2021. The Division is hereby notifying you that permit SW8 090632 has been renewed
on June 7, 2021, and shall be effective until December 30, 2029. 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 July 2, 2009 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 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 [phone] or [e-mail].
Sincerely,
C4 2ko

1 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 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 operation 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
