Greater Welch's Chapel Baptist Church
High Density Project
Chowan County
Dear Mr. Saunders:
The Washington Regional Office received a Stormwater Management Permit
Application for renewal of the subject permit on September 10, 2020. Staff review of the
applications have determined that the permit can be reissued. We are forwarding Permit
No. SW7100904 dated October 2, 2020, for the continued operation of the subject
project.
This permit, upon its effective date, will replace all previous State Stormwater permits for
this project. This permit shall be effective from February 1, 2021 until January 31, 2029
and shall be subject to the conditions and limitations as specified therein, and does not
supercede any other agency permit that may be required. 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.
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, 6714 Mail Service Center, Raleigh, NC 27699-6714.
Unless such demands are made this permit shall be final and binding.
If you have any questions, or need additional information concerning this matter, please

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. SEP 9 2010
This system (check one):
❑ does ® does not incorporate pretreatment other than a forebay."t v
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.
