Comparison: State vs. Federal

Rules. Washington's listed wastes are regulated hazardous wastes that are listed in the state's Dangerous Waste Regulations in WAC 173-303-9903 to 173-3-3-9904. Checking the lists is the first step in designating your waste.

These wastes are specifically listed as hazardous. Other wastes may be regulated because they exhibit certain hazardous waste characteristics (ignitability, corrosivity, reactivity, toxicity). See the state section CHARACTERISTIC WASTE for more information.

WDOE allows petitioners to delist classes of waste as long as the class of waste is not regulated under the federal regulations covering listing and identification of wastes. See the state section DELISTING PETITIONS for more information.

Administration and enforcement. WDOE's Hazardous Waste and Toxics Reduction Program administers and enforces the DW, EHW, and special waste rules in Washington.
