• Rules. Montana incorporates by reference the federal rules for identifying and classifying hazardous waste, including the federal exclusion that conditionally excludes cathode-ray tubes from the definition of solid waste. Check with the Montana Department of Environmental Quality (DEQ) to see whether the state has yet adopted any of these more recent federal conditional exclusions from the definitions of hazardous and/or solid waste: the 2015 solid waste exclusion for recycling of certain hazardous secondary materials; the solid waste and hazardous waste exclusions for solvent-contaminated wipes; and the hazardous waste exclusion for carbon dioxide streams in geological sequestration activities.
• Administration and enforcement. DEQ's Waste and Underground Tank Management Bureau administers and enforces the state's hazardous waste determination rules.
