Coast Guard Marine Safety Detachment Ketchikan personnel are working with responders to assess and mitigate pollution from the 60-foot Silver Bay II that reportedly sank at its moorings at the Wrangell Silver Bay logging sawmill along Zimovia Strait Wednesday. Containment boom has been mobilized around the site of the sinking and the owner of the vessel has hired divers to conduct an assessment of the vessel and cap fuel tanks. Dive operations have been placed on hold due to weather, which has delayed the salvage company’s transit and arrival time. Coast Guard personnel are on site and are working with the owner, Alaska Department of Environmental Conservation and other federal, state and local agency partners to develop a response plan.
