A barge with a 5-ton crane aboard sank in Gig Harbor Saturday morning, spilling an unknown amount of oil into the harbor.
The state Department of Ecology and Gig Harbor fire and police departments are responding.
The barge is owned by a company called Marine Floats.
The sunken barge has leaked an unknown amount of fuel, causing an oil sheen on the water.
According to the State Department of Ecology, the fuel has been removed from the barge crane. The barge owner has deployed boom and absorbent materials to help contain the spill, according to the Ecology Department.
