To facilitate safe manoeuvring and berthing of vessels, capital dredging of marine sediment and rock will be required at two berth areas, located south of Frederick Point, and at the Materials Off-Loading Facility. The data presented herein will be used to support the assessment of potential project effects on water quality, and to evaluate management options for dredged sediment. If sediment is deemed suitable for disposal at sea, this information will also be used to prepare an application for ocean disposal of dredged material under the Canadian Environmental Protection Act, 1999.
