The tugboat, Island Champion, became grounded in the Steamboat Slough of the Snohomish River at about 1830 4/15/07. An estimated 150 gallons of red-dyed diesel fuel was spilled to the water and an additional approximate 1500 gallons was removed from the vessel's fuel tanks before it could spill. Most of the spilled fuel oil was immediately contained with hard boom and is believed to have been recovered with absorbent pads within about 16 hours of the spill. The vessel was re-floated later in the evening of 4/16/07. Please see the first and final Pollution Report for further information.
