Dear Mr. Paul:
The Division of Energy, Mineral and Land Resources received a complete 8-year Permit Renewal Application for
the subject permit on August 10, 2022. The Division is hereby notifying you that permit SW888101 1 has been
renewed, updated, and re -issued on August 24, 2022, as attached. Please be aware that the renewal and re -

This permit shall be effective until October 9, 2029 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

This permit is effective only with respect to the nature and volume of stormwater described in
the application and other supporting data.
2. This stormwater system has been approved for the management of stormwater runoff as
described in Section 1.8 of this permit. The stormwater control has been designed to handle
the runoff from 94,756 square feet of impervious area.
A 50' wide vegetative buffer must be provided and maintained adjacent surface waters,
measured horizontally from and perpendicular to the normal pool of impounded structures, the
top of bank of both sides of streams and rivers and the mean high water line of tidal waters.
A vegetated filter strip is not required for this pond as it has been designed for a 90% total
suspended solids removal efficiency.

Wet Detention 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.
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
be repaired immediately.
