East berth maintenance dredging – Alliance Grain Terminal

The proposed project is to dredge ~6,500 cubic metres of sediment over a 4,500 square metre area to restore the East berth to the 1995 depths of 13.7 m (45 ft). This berth has not been dredged since 1995, when the pocket was blasted and dredged to increase berth depth for larger vessel access.

Dredging is proposed to be conducted from the water using a barge-mounted crane equipped with a clamshell bucket. Based on sediment characterization at the site, sediments tested are considered contaminated = IL+. Dredged sediment will be loaded onto one or more designated material barge(s) for transport off-site for disposal at an appropriate upland facility. Some sediment is likely to be spilled grain, while other sediment appears to be the result of the three nearby combined storm outfalls, which discharge sediment and debris during rainfall events. Other sediment may have originated from surrounding areas which are not as deep, as a result of marine currents or tug wash. Anthropogenic debris in the area to be dredged includes steel pieces, a tire, and many small bits of garbage.
