Subject: Permit Renewal
State Stormwater Management Permit No. SW8 090528
Brunswick Unit 1- Capacitor Bank

Dear Mr. Ratcliff:
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 17, 2021. The Division is hereby notifying you that permit SW8 090528 has been renewed
on June 23, 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 July 23, 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 150E 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.

elements noted in the inspection will be corrected, repaired or replaced in a time
manner. 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 be watered twice weekly if needed until the plants become established
(commonly six weeks).
— Once a year, the filter strip will be reseeded, if needed, 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 in a timely manner.
