Comparison: State vs. Federal
• Rules. Oklahoma adopts by reference the U.S. Environmental Protection Agency's (EPA) Hazardous Waste Generator Improvements Rule, effective in Oklahoma as of September 15, 2018. The state follows the federal requirements for making hazardous waste determinations. In connection with the federal exclusions for solid and/or hazardous waste, the state adopts almost all of them, including the conditional exclusions from the definitions of solid waste as they apply to cathode-ray tubes and solvent-contaminated wipes, the exclusion from the definition of solid waste for recycling certain hazardous secondary materials, and the hazardous waste exclusion for carbon dioxide streams in geologic sequestration activities. The state rules differ from the federal in connection with the description of listed waste F019, and the state does not adopt the conditional exclusion from the definition of hazardous waste concerning the disposal of solvent-contaminated wipes.
