Comparison: State vs. Federal
• Rules. Washington follows the federal requirements for generators accumulating (storing) hazardous waste on-site without a permit through its adoption of the U.S. Environmental Protection Agency's (EPA) Hazardous Waste Generator Improvements Rule, effective in Washington on April 30, 2019. The state has more stringent hazardous waste storage requirements in connection with dangerous waste storage tanks, surface impoundments, dangerous waste storage facilities, and generators accumulating dangerous wastes on-site.
• Administration and enforcement. The Washington Department of Ecology's (WDOE) Hazardous Waste and Toxics Reduction Program administers and enforces the dangerous waste storage requirements in Washington.
