Coast Guard personnel responded to a 42-foot commercial fishing vessel after it sank while moored in the Hoquiam River Wednesday.
Global Diving and Salvage personnel placed containment boom around the sunken vessel Wednesday night and removed an estimated 200 gallons of marine diesel from the fuel tanks Thursday morning, according to a statement from the Coast Guard.
The Coast Guard received a report at 3:40 p.m. from Hoquiam Police Department personnel that the vessel Perwyn, with a maximum potential of 800 gallons of diesel aboard, had sunk and there was a sheen on the surrounding water.
Members from the Coast Guard Sector Columbia River Incident Management Division opened the Oil Spill Liability Trust Fund for up to $50,000 and contracted Global Diving and Salvage marine casualty responders for cleanup purposes.
An absorbent boom has been left in place and members of the Washington Department of Ecology will continue to monitor the site.
