Please give a brief project description below. *

The proposed maintenance dredging will occur via hydraulic dredging
(cutter suction) to dredge the material to -36' MLW + 2' overdredge.
Mechanical dredging via clamshell may also be utilized in locations
within the dredge area where timber inhibits the use of hydraulic
dredging. A total of approximately 17,000 cubic yards of material will
be dredged. Dredging equipment will be stored at the berth until the
maintenance dredging is complete. The maintenance dredging is
expected to take approximately 2 weeks to complete. The
hydraulically dredged material will be pumped (booster pump) to the
CDF via a pipeline sunken down to the river bottom. The dredged
material will be discharged at the existing CDF, which is located
directly across Cape Fear River from the dredge area and the CDF
will be isolated by an earthen berm. After the dredged material is
placed in the isolated area, effluent will drain back to the river in a
controlled manner through a strategically placed weir. An excavator
or bulldozer will be used to spread dredge material during disposal.
The mechanically dredged material will be transported and stored via
barge.
National Gypsum Company uses the facility for unloading gypsum for
wallboard production at the wallboard plant across River Road. Daily
operations will be able to continue when the maintenance dredging is
complete. If the berthing area is not dredged, there will be a
significant negative impact to the operations at the National Gypsum
Wilmington facility.
Please give a couple of dates you are available for a meeting.
Please attach the documentation you would like to have the meeting about.
