VALDEZ -- The Coast Guard is monitoring a 49-foot fishing vessel after the crew intentionally grounded it after hitting a rock in Main Bay in Prince William Sound.

The vessel is close to a salmon hatchery so Coast Guard crews are watching for signs of diesel and oil pollution after Monday's grounding. Two crew members aboard the vessel Raidawn safely transferred to another boat.

A Coast Guard helicopter crew spotted a 20-by-15-foot sheen near the grounded ship. The Raidawn reportedly carried about 3,200 gallons of diesel fuel and 500 gallons of gasoline.

The agency has ordered the Raidawn's owner to remove all the fuel and make satisfactory temporary repairs before trying to tow the vessel to Cordova.

Alaska Marine Response has been hired by the vessel's owner to deploy boom and assist with fuel removal.
