Dear Mr. Heins:
APR 14 2012
DW[Q-
Dee Freeman
Secretary
The Stormwater Permitting Unit received a complete Stormwater Management Permit Application for SOF
Admin / COF on March 21, 2012. Staff review of the plans and specifications has determined that the project,
as proposed, will comply with the Stormwater Regulations set forth in Title 15A NCAC 2H.1000 and Session
Law 2006-246. We are forwarding Permit No. SW6120204, dated March 23, 2012, for the construction,
operation and maintenance of the subject project and the stormwater BMPs.
This permit shall be effective from the date of issuance until March 23, 2020 and shall be subject to the
conditions and limitations as specified therein, and does not supersede any other agency permit that may be
required. Please pay special attention to the conditions listed in this permit regarding the Operation and
Maintenance of the BMP(s), recordation of deed restrictions, procedures for changes of ownership,
transferring the permit, and renewing the permit. Failure to establish an adequate system for operation and
maintenance of the stormwater management system, to record deed restrictions, to follow the procedures for
transfer of the permit, or to renew the permit, will result in future compliance problems.
If 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) days following receipt of this permit.
This request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina
General Statutes, and filed with the Office of Administrative Hearings, P.O. Drawer 27447, Raleigh, NC 27611-
7447. Unless such demands are made this permit shall be final and binding.
This project will be kept on file at the Fayetteville Regional Office. If you have any questions, or need additional
information concerning this matter, please contact Robert Patterson at (919) 807-6375; or at
robert.patterson@ncdenr.gov.
Sincerely,
for Charles Wakild, P.E.

runoff as described in Section 1.8 of this permit. The stormwater control has been
designed to handle the runoff from 55,756 square feet of impervious area.

5. All stormwater collection and treatment systems must be located in either
dedicated common areas or recorded easements. The final plats for the project
will be recorded showing all such required easements, in accordance with the
approved plans.

Infiltration Basin Operation and Maintenance Agreement
1 will keep a maintenance record on this BM. This maintenance record will be kept in a
log in a known set location. Any deficient BM[' 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.

A visible laver of sediment

How I will remediate the problem:
Search for the source of the
sediment and remedy the problem if
possible. Remove the sediment and
dispose of it in a location where it
will not cause impacts to streams or
the BMP.
Provide additional erosion
protection such as reinforced turf
matting or riprap if needed to
prevent future erosion problems.
Remove the weeds, preferably by
hand. If pesticides are used, wipe
them on the plants rather than
spraying.
Search for the source of the
sediment and remedy the problem if
possible. Remove the sediment and
dispose of it in a location where it
will not cause impacts to streams or
the BMP. Replace any media that
was removed in the process.
Revegetate disturbed areas
immediately.
Replace the top few inches of filter
media and see if this corrects the
standing water problem. If so,
revegetate immediately. If not,
consult an appropriate professional
for a more extensive repair.
Remove the plants by hand or by
wiping; them with pesticide (do not
sprav).
Remove shrubs or trees
immediately.
