Subject: Stormwater Permit No. SW7081206
South Mills Substation
High Density Stormwater Project
Camden County
Dear Mr. Furr:
The Washington Regional Office received a Stormwater Management Permit
Application for the subject project, located on December 16, 2008. 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.
We are forwarding Permit No. SW7081206 dated February 18, 2009, for the
subject project. FZ f 301-24
This permit shall be effective from the date of issuance until February 18, 2019,
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 and in the submitted application. Failure to establish an adequate system
for operation and maintenance of the stormwater management system 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 150E 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.

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.

❑ does ® does not incorporate pretreatment other than a forebayD01'r k 'NA i f)
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.
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.
