documentation is attached If the applicant has designated an agent in the Stormwater Management Permit
Application Form, the agent may initial below Attach justification if a requirement has not been met.

IV. INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT
1 After every runoff producing rainfall event and at least monthly inspect the infiltration system for erosion,
trash accumulation, vegetative cover, and general condition
2 Repair eroded areas immediately, re -seed as necessary to maintain adequate vegetative cover, mow
vegetated cover to maintain a maximum height of six inches, and remove trash as needed
3 After every runoff producing rainfall event and at least monthly inspect the bypass, inflow and overflow
structures for blockage and deterioration Remove any blockage and repair the structure to approved
design specifications
4 Remove accumulated sediment from the pretreatment system and infiltration basin annually or when
depth in the pretreatment unit is reduced to 75% of the original design depth The system shall be restored
to the original design depth without over -excavating Over -excavating may cause the required water
table separation to be reduced and may compromise the ability of the system to perform as designed
Removed sediment shall be disposed of in an appropriate manner and shall not be handled in a manner
that will adversely impact water quality (i a stockpiling near a stormwater treatment device or stream,
etc.)
A benchmark shall be established in the pretreatment unit The benchmark will document the original
design depth so that accurate sedtment accumulation readings can be taken The measuring device used
to determine the depth at the benchmark shall be such that it will give an accurate depth reading and not
readily penetrate into accumulated sediments
When the design depth reads •'7S — feet in the pretreatment unit, the sediment shall be
removed from both the pretreatment unit and the infiltration basin.
5 If the Division determines that the system is failing, the system will immediately be repaired to original
design specifications If the system cannot be repaired to perform its design function, other stormwater
control devices as allowed by NCAC 2H 1000 must be designed, approved and constricted
I acknowledge and agree by my signature below that I am responsible for the performance of the five
maintenance procedures listed above I agree to notify DWQ of any problems with the system or prior to any
changes to the system or responsible party

Footnotes
When using the Division SA/DA tables, the correct SA/DA ratio for permanent pool sung should be computed based upon the
actual impervious % and permanent pool depth Linear interpolation should be employed to determine the correct value for non-
standard table entries
In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90% TSS removal The NCDFNR BW manual provides design tables for both 85% TSS removal and 90% TSS removal

1 After every significant runoff producing rainfall event and at least monthly
a. Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition
b Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within
2 to 5 days as designed
2 Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed
3 .inspect and repair the collection system (i a catch basins, piping, swalcs, nprap, etc ) quarterly to maintain
proper functioning
4 Remove accumulated sediment from the wet detention basin system semi-annually or when depth is
reduced to 75% of the original design depth (see diagram below) Removed sediment shall be disposed of
in an appropriate manner and shall be handled in a manner that will not adversely impact water quality (i e
stockpiling near a wet detention basin or stream, etc )

Location of Property The project site is a cleared parcel behind the Shallotte Church of God, 286 Brick
Landing Rd , Shallotte, Brunswick County, North Carolina
Description of Unauthorized Activity Unauthorized activities include mechanical clearing, dredging,
and sidecastmg of sediments in jurisdictional wetlands The cleared wetlands on site are part of a pocosin
dominated by pond and loblolly pine, gall berry, and fetterbush plants The wetland is hyrdologically
connected to the Shallotte River, a designated water of the U S
During an April 1, 2004 inspection of the referenced property, U S Army Corps of Engineers staff
documented disturbance activities in jurisdictional wetlands A review of district records indicates that
the U S Army Corps of Engineers has not authorized these activities Initial calculations show that
unauthorized impacts— dredging with sidecasting and mechanical clearing ---to jurisdictional waters of

Remedial Action Requested
We will welcome any evidence you may have to demonstrate that the described work has been authorized
by the Army Corps of Engineers If the project has not been authorized, we request that the site be
restored Prior to restoration, please submit a restoration plan and sketch for Corps review and approval
On April 5, 2004, Pastor Gibson telephoned this office and stated that he intends to restore the site The
plan should include specifications for removal of the fill and regrading to oiiginal wetland elevations
Please submit the plan to the letterhead address (attn Thomas Farrell) within 30 days after receiving this
letter
All removed material must be deposited on upland and stabilized to prevent its return to waters of the
U S Erosion and control measures may include a silt fence, hay, or straw and must be installed as
necessary during construction to prevent sediment from eroding into adjacent waters and wetlands The
plan should include specifications for replanting the disturbed areas with appropriate native wetland
vegetation
