Our "zero spills" strategy helps prevent oil and hazardous substances from entering state waters. Our spill prevention requirements apply to industries that handle or transport oil in Washington, such as large vessels, refineries, oil storage and marine fueling terminals, mobile oil suppliers, and certain marinas and boatyards. Our prevention work includes assessing the potential risks that oil transportation poses to people and the state's major waterways, Puget Sound, and the Columbia River.
Evaluations of spill prevention plans and operations manuals, oil-handler training and certifications, inspections, and technical assistance help industries meet our prevention requirements while protecting Washington's environment. We also conduct spill investigations to seek out causes of spills and provide recommendations for prevention of future incidents.
