Hazardous waste management system; identification and listing of hazardous waste--EPA. Final rule and response to comments.

On May 19, 1980, as part of its regulations implementing section 3001 of the Resource Conservation and Recovery Act (RCRA). EPA promulgated a series of criteria for listing wastes as hazardous. On July 19, 1991, the Agency proposed to conform the language of the regulation to reflect the Agency's intent and consistent interpretation of that regulation. Today's rule finalizes the proposed rule.
