• Rules. Missouri incorporates and follows the federal regulations for identifying and managing characteristic hazardous wastes, including the criteria for identifying hazardous waste by the characteristics of ignitability, corrosivity, reactivity, and toxicity. The federal characteristic waste requirements are described in the national section CHARACTERISTIC WASTE.
Wastes may be classified as hazardous because of their characteristics or if they have been placed on hazardous waste lists by the Environmental Protection Agency (EPA). Missouri has additional regulations in connection with dilution, exclusions from the solid waste and hazardous waste definitions, and additional state-listed hazardous wastes. See the state section LISTED WASTES for additional guidance.
Although Missouri has received EPA authorization to administer the federal Resource Conservation and Recovery Act (RCRA) rules, the Missouri Department of Natural Resources (DNR) does not have authority to delist RCRA wastes under federal rules 40 CFR 260.22. EPA Region 7 is responsible for administering and enforcing the rules for hazardous waste delisting petitions in Missouri. See the national section DELISTING PETITIONS for more information.
