Comparison: State vs. Federal

Rules. Oregon has adopted by reference the federal regulations for identifying and classifying hazardous waste, including the federal conditional exclusion from the definition of solid waste for cathode-ray tubes. Although the state has adopted the federal rules "through June 30, 2014," the state has specifically not adopted several federal hazardous waste exclusions that were adopted under the federal rules by that date, such as those for solvent-contaminated wipes and for carbon dioxide streams in geological sequestration activities. In addition, Oregon modifies two federal exclusions from the definitions of hazardous waste and solid waste.

Oregon also regulates certain additional wastes, including various residues, as state-only hazardous wastes. See the state section LISTED WASTES for more information.

Administration and enforcement. The Oregon Department of Environmental Quality's (DEQ) Land Quality Division administers and enforces the hazardous waste identification and classification rules in Oregon.
