SUBJECT: Stormwater Management Permit SW6100203
New Maintenance Building for the Village of Whispering Pines
High Density Project
Moore County
Dear Mr. DeBolt:
Dee Freeman
Seer
�u�„�el<..ry
The Fayetteville Regional Office of the Division of Water Quality received a complete Stormwater
Management Permit Application for the New Maintenance Building for the Village of Whispering
Pines project on February 1, 2010. Staff review of the plans and specifications, along with additional
information received on February 8, 2010, has determined that the project, as proposed, will comply
with the Stortmwater Regulations set forth in Title 15A NCAC 211 .1000. Therefore, we are forwarding
herewith Stormwater Management Permit SW6100203 dated February 19, 2010, for the construction,
operation, and maintenance of stormwater treatment facilities associated with the subject project.
This permit shall be effective from the date of issuance until February 18, 2020 and shall be subject to
the conditions and limitations as specified therein. Please pay special attention to the Operation and
Maintenance requirements in this permit. Failure to establish an adequate system for operation and
maintenance of the stormwater management system will result in future compliance problems.
I f any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to
request an adjudicatory hearing upon written request within thirty (30) calendar days following receipt
of this permit. This request must be in the form of a written petition conforming to Chapter 15013 of the
North Carolina General Statutes and filed with the Office of Administrative Hearings, PO Drawer
27447, Raleigh, NC 2761 1-7447. Unless such demands are made this permit shall be final and binding.
If you have any questions, or need additional information, please contact Mike Lawyer or myself at
(910) 433-3300.
Sincerely,
Belinda S. Henson

areas or recorded easements. The final plats for the project will be recorded showing all such
required easements in accordance with the approved plans.
5. The runoff from all built -upon area within the permitted drainage area of this project must be
directed into the permitted stormwater control system.
6. The built -upon area associated with this project shall be located at least 30 feet landward of all
perennial and intermittent surface waters.

Infiltration 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.
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.
