Comparison: State vs. Federal

Rules. At present, Washington has no commercial landfills that accept dangerous waste (DW) or extremely hazardous waste (EHW). However, the state's DW management program retains DW landfill regulations that follow the federal rules and additional state requirements. The state's regulations for DW landfills focus on disposal restrictions, location standards, performance standards, and lab packs. The state has a special facility at Hanford that manages the DW and EHW generated exclusively on that site.

Washington has its own rules for solid (nondangerous) waste landfills. The federal solid waste landfill requirements also apply in Washington. See the state section SOLID WASTE for more information.

Administration and enforcement. WDOE administers and enforces both the dangerous and solid (nondangerous) waste landfill requirements in Washington.
