Dear Ms. Higgins:
On behalf of the U.S. Army's Military Ocean Terminal at Sunny Point ( MOTSU), enclosed
is a "For Record Only" Pre - Construction Notification regarding proposed releases of return
water from Disposal Area (DA) 4 located on the MOTSU facility near Southport, Brunswick
County, North Carolina.
The DA 4 is located on the southern side of the MOTS,U facility. It is a diked upland
disposal site and has a functioning outfall structure and pipe that discharge into open water of the
Cape Fear River. MOTSU proposes to release water on an as- needed basis. Projects anticipated
to require a release of water include maintenance dredging of MOTSU'"s basins and channels in
the Cape Fear River and ditching of the interior of DA 4 for the purpose of drying out soil for a
future dike raise, and periodic releases of rainwater that accumulates during times of non -use of
the DA. All discharges of return water will be in compliance with conditions of the North
Carolina Division of Water Resources' General Certification No. 3888 and the U.S. Army Corps
of Engineers' Nationwide Permit No. 16.
Should you have any questions or need additional information, please contact Mr. Jeff
Richter of my staff at (910) 251 -4636.

B (3")(d) Explain the purpose of the project
Water currently contained within the DA will be released thru the outfall structure and pipe
Projects anticipated to require a release of water include periodic maintenance dredging of MOTSU's
basins and channels in the Cape Fear River and ditching of the interior of DA 4 for the purpose of drying
out soil for a future dike raise, and periodic releases of rainwater that accumulates during times of non-
use of the DA All releases will be in compliance with all conditions of GC #3888 and the US Army Corps
of Engineers' Nationwide Permit #16
B (3)(e) Describe the overall project in detail, including the type of equipment to be used.
Projects anticipated requiring a release of water include periodic maintenance dredging of MOTSU's
basins and channels in the Cape Fear River and ditching of the interior of DA 4 for the purpose of drying
out soil for a future dike raise, and periodic releases of rainwater that accumulates during times of non-
use of the DA
Maintenance dredging projects at MOTSU in which dredged material is disposed in the DA will involve
discharging the dredged mix as far as possible from the outfall structure to allow for maximum settling
of sediments prior to release of return water
Prior to ditching, any existing ponded water will be released through the existing,outfall structure and
outfall pipe to discharge into open water adjacent to the Cape Fear River. This release is necessary to
facilitate the ditching, which will allow the surface soil to drain and dry. Excavated soil will be retained
in the DA's dikes The ditching will be performed by a tractor or excavator with all excavated material
stockpiled beside the ditches No excavated material will be placed in wetlands or in a location that
allows erosion into waters or wetlands
When return water is being released through the outfall pipe, turbidity at the discharge end will be
monitored to ensure compliance with General Water Quality Certification #3888. The rate of discharge
is controlled at�fhe outfall structure in the'DA.
B (15)(b) Explanation of permits or certifications obtained in the past.,
The majority of MOTSU maintenance dredging is conducted by mechanical means (clamshell, bucket,
etc) with disposal in the Wilmington Ocean Dredged Material Disposal Site (ODMDS) The dredging,
regardless of method, and disposal in either ODMDS or an upland site has been determined to be
consistent with the North Carolina Coastal Management Program by concurrence letter dated July 11
1980 (SCH File #071 -80) and June 12, 1995 (CD95 -09). The dredging project has not changed in scope
since the 1995 concurrence.
Dredged material has been discharged'in DA 4 in the past, and each event has obtained project - specific
approval for the release of effluent into the Cape Fear River. The last time effluent was discharged from
DA 4 in association with a maint dredging project Was,in 2003 MOTSO obtained required Corps'
Regulatory and NC Div Water Resources (NCDWQ in 2003) approvals for the specific project
B(6)(b). Future Project Plans: is this a phased project?
Projects anticipated to require a release of water include periodic maintenance dredging of MOTSU's
basins and channels in the Cape Fear River and ditching of the interior of DA 4 for the purpose of drying
out soil for a future dike raise, and periodic releases of rainwater that accumulates during times of non-
use of the DA

The majority of MOTSU maintenance dredging is conducted by mechanical means (clamshell, bucket,
etc) with disposal in the Wilmington Ocean Dredged Material Disposal -Site DA 4 will, be used for the
disposal of dredged material when necessary, determined by the availability of dredge plant, funding
requirements and availability, timing, etc
Ditching will be done for the purpose of drying out soil within DA 4 for subsequent raising of the dikes
The discharge location of dredged material into the DA will be as far from the spillway as possible to
allow for maximum settling of sediments prior to release of return water Compliance with all
conditions, including limits of acceptable turbidities, of the appropriate GC (currently GC #3888) and
Corps Regulatory Nationwide Permit #16 will occur for the duration of each release event
