DESCRIPTION OF UNLOADING OPERATIONS

Material will be dredged by clamshell from the borrow area and loaded onto a deck barge
where it will be dewatered. The barge when full will be towed to the off-loading site and
maintained in position alongside the conveyor barge. The front end loader will load
material from the piles of aggregate into a feed hopper which will feed the transfer
conveyor mounted on the deck barge. The transfer conveyor will feed the material into a
hopper mounted on the conveyor barge and onto the main conveyor. This conveyor will
extend over the shoreline to the truck staging area where the material will be loaded into
dump trucks.

The conveyor barge is not expected to ground at low water, but if x: appears that this
occurrence is likely: °

a shallow draft deck barge will be mounted under the conveyor to act as a spill
deck, or

operations will be suspended. and the conveyor barge moved to deep water until
the depth is sufficient. 7

Spillage due to this method is minimized or eliminated by the use of conveyors. and the
close moorage between the conveyor barge and the bulkhead and between the deck barge
and the conveyor barge. | |
