Post -Construction Stormwater Management Permit No. SW8 081222
Pump Station 35 Expansion
New Hanover County
Dear Mr. Theberge:
Effective August 1, 2013 the Post -Construction Stormwater Management 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 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 enforcement 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 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 Division of Energy, Mineral and Land Resources received a complete 8-year Permit Renewal Application for
the subject permit on June 10, 2022. The Division is hereby notifying you that permit S WO81222 has been
renewed, updated, and re -issued on June 20, 2022, as attached. As requested, a copy of the current operation and
maintenance agreement is also enclosed. Please be aware that the renewal and re -issuance of this stormwater
Penn it does not imply that the site is currently in compliance.
This permit shall be effective until February 27, 2027, which includes all available extensions, and does not
supersede any other agency permit that may be required. The project shall be subject to the conditions and
limitations as specified therein. This permit does not impose new or increased stormwater control requirements; it
clarifies the rules and requirements of this program to provide you with a better understanding of your obligations
under this permit. Failure to comply with these requirements will result in future compliance problems. Please
note that this permit is not transferable except after notice to and approval by the Division.
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
OA14 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 concerning this permit, please contact Ashley Smith in the Wilmington Regional
Office, at [phone] or [e-mail].

Sand Filter 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 sand filter.
— The sedimentation chamber or forebay will be cleaned out whenever sediment depth exceeds
six inches.
— Once a year, sand media will be skimmed.
— The sand filter media will be replaced whenever it fails to function properly after maintenance.
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 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.
