Establishes the oil transportation safety act.

Establishes appropriate measures to reduce the risk of oil spills from vessels, encourages the adoption of spill prevention measures by transporters of oil by vessel, ensures that the public has access to information about the movement of oil through the state, and ensures that communities are fully informed about any risks posed to their safety by the transportation of oil.

Requires the department of ecology to work with the United States coast guard to urge that, with respect to the shared inland marine waters of Puget Sound and coastal approaches to Puget Sound, the appropriate provincial and national regulatory entities in Canada require comparable oil transportation safety standards to that required under this act.
