Subject: Permit Renewal
State Stormwater Management Permit No. SW8 090625
Centralized Washrack
Onslow 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 90625 has been renewed on
June 7, 2021, and shall be effective until December 30, 2029For 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 28, 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,

I will keep a maintenance record on this BMP. This maintenance record will bekept in
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 after the filter strip is established, any newly planted vegetation
will he watered twice weekly if needed until the plants become established
(commonly six weeks).
— Once a year, the filter strip will be reseeded to maintain a dense growth of
vegetation
— Stable groundcover will be maintained in the drainage area to reduce the
sediment load to the vegetation.
— Two to three times a year, grass filter strips will be mowed and the clippings
harvested to promote the growth of thick vegetation with optimum pollutant
removal efficiency. Turf grass should not be cut shorter than 3 to 5 inches and
may be allowed to grow as tall as 12 inches depending on aesthetic requirements
(NIPC, 1993). Forested filter strips do not require this type of maintenance.
— Once a year, the soil will be aerated if necessary.
— Once a year, soil pH will be tested and lime will be added if necessary.
After the filter strip is established, it will be inspected quarterly and within 24 hours
after every storm event greater than 1.0 inch (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.

Infiltration 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.
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.
