On or about October 13, 2004 the tank vessel POLAR TEXAS, owned by Polar Tankers, Inc., discharged crude oil into waterways in or near Dalco Passage, Washington. The oil washed ashore on Vashon and Maury Islands in the Dalco Passage area off Commencement Bay.
The Natural Resource Trustees alleged that the spill caused injuries to various intertidal and subtidal species, including Puget Sound Chinook salmon and other salmonids, Hardshell Clams, Surf Smelt, and Sand Lance, and their habitats, as well as birds and other wildlife. The spill resulted in oiling and temporary closures of beaches on Vashon and Maury Islands. A settlement agreement between the responsible party and the trustees was developed to compensate the public for damages to natural resources.
