Subject: Permit Renewal
Post -Construction Stormwater Management Permit No. SW8080717
H & S Hotel
Carteret County
Dear Mr. Holz:
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 2009406. 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 November 17'", 2022. The Division is hereby notifying you that permit SW8080717 has
been renewed, updated, and re -issued on January 3rd, 2023, 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 permit does not imply that the site is currently in compliance.
This permit shall be effective until December 30', 2029, 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 thisprogram to provide you with a better understanding of your obligations
under this permit. Failure to comply withthese 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
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.

Filter Strip, Restored Riparian Buffer and Level Spreader
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:
— 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 to maintain a dense growth of
vegetation
— Stable groundcover willbe 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.

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 of the infiltration trench will be carefully managed to reduce
the sediment load to the sand filter.
— The water level in the monitoring wells will be recorded once a month and after
every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County).
The infiltration trench 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). Recorc

Infiltration Trench 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 of the infiltration trench will be carefully managed to reduce
the sediment load to the sand filter.
— The water level in the monitoring wells will be recorded once a month and after
every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County).
The infiltration trench 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.
