Subject: Stormwater Permit Renewal
Stormwater Management Permit SV 7080904
The Shoppes at 10.5
Dare County
Dear Mr. Tillman:
A Division of Energy, Mineral, and Land Resources file review has determined that
Stormwater Permit SV 7080904 for a stormwater treatment system consisting of an
infiltration system serving the Shoppes at 10.5 located at 2515 S Croatan Highway,
Nags Head, NC expires on December 30, 2021. This is a reminder that permit renewal
applications are due 180 days prior to expiration. We do not have a record of receiving
a renewal application.
Please submit a completed permit renewal application along with a $505.00 fee for
permit renewal. Also, it was noted in the file review that a designer's certification that the
project was constructed in accordance with the approved plans as required by the
permit has not been submitted. Please include this with your application. Permit
application forms for renewal can be found on our website at:
https://deq. nc.gov/about/divisions/energy-mineral-and-land-
resources/stormwater/stormwater-program/post-construction-2. North Carolina General
Statutes and the Coastal Stormwater rules require that this property be covered under a
stormwater permit.
If you have questions, please feel free to contact me at (252) 948-3923. 1 will be glad to
discuss this by phone or meet with you. If you would like, I can e-mail you a copy of the
application forms. You can request a copy by e-mailing me at
roger.thorpe(a)ncdenr.gov.

Infiltration Basin Operation and Maintenance Agreement
N/ L NO�.Y-H19ARL)
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.

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 operation and maintenance procedures:
— Stable groundcover will be maintained in the drainage area to reduce the sediment
load to the permeable pavement.
— The area around the perimeter of the permeable pavement will be stabilized and
mowed, with clippings removed.
— Any weeds that grow in the permeable pavement will be sprayed with pesticide
immediately. Weeds will not be pulled, since this could damage the fill media.
— Once a year, the permeable pavement surface will be vacuum swept.
— At no time shall wet sweeping (moistening followed by sweeping) be allowed as a
means of maintenance.
— There shall be no repair or treatment of Permeable Pavement surfaces with other
types of pavement surfaces. All repairs to Permeable Pavement surfaces must be
accomplished utilizing permeable pavement which meets the original pavement
specifications.
— Concentrated runoff from roof drains, piping, swales or other point sources,
directly onto the permeable pavement surface shall not be allowed. These areas
must be diverted away from the permeable pavement.
Initial Inspection: Permeable Pavements shall be inspected monthly for the first three
months for the following:
