Oklahoma Department of Environmental Quality (DEQ) Land Protection Division Hazardous Waste Section
See national section for basic information and federal regulations.
Comparison: State vs. Federal
• Rules. Oklahoma incorporates by reference the federal regulations for identifying and classifying hazardous waste. Because the state incorporates the federal rules that were in effect as of July 14, 2014, the federal conditional exclusions from the definitions of solid and hazardous waste as they apply to cathode-ray tubes and solvent-contaminated wipes, and the hazardous waste exclusion for carbon dioxide streams in geologic sequestration are in effect in Oklahoma. Check with the Oklahoma Department of Environmental Quality (DEQ) to see whether the state has yet adopted the 2015 exclusion from the definition of solid waste for recycling of certain hazardous secondary materials.
See the national section HAZWASTE DETERMINATION (CLASSIFICATION) to review the federal rules.
• Administration and enforcement. DEQ's Land Protection Division administers and enforces the state's hazardous waste determination rules.
