We focus on preventing oil spills to water and land, and planning for and delivering a rapid, aggressive, and well-coordinated response. Every year, 20 billion gallons of oil are transported through Washington by vessel, rail, and pipeline, posing significant risk of environmental damage. We're designated to coordinate response efforts to oil and hazardous material spills that threaten or impact state waters. Our requirements for prevention and preparation allow a quick and thorough response. Training and certification requirements, inspections, and technical assistance help industries protect the environment. Prevention and response plans help industry and communities practice and prepare for spills.
