Comparison: State vs. Federal
• Rule. Missouri adopts by reference the federal rules 40 CFR 260 for petitions to delist hazardous wastes under the federal Resource Conservation and Recovery Act (RCRA) as it does not have EPA authority to delist RCRA wastes. For additional information see the national sections DELISTING PETITIONS and LISTED WASTES.
However, EPA Region 7 recommends that persons filing a delisting petition first contact DNR for any procedures that may have to be followed for the particular waste for which delisting is sought.
Note: The waste may still be hazardous if it demonstrates certain characteristic properties such as ignitability or toxicity. See the national section CHARACTERISTIC WASTE for more information.
• Administration and enforcement. EPA Region 7 administers and enforces the rules for delisting petitions in Missouri. DNR is responsible for reviewing delistings that have received EPA approval.
10 CSR 25-3.260(2)(C)
Within 60 days after a favorable delisting determination by EPA Region 7, DNR will either approve or disapprove the delisting. If DNR fails to take action on a final EPA Region 7 determination within 60 days, the delisting is considered approved.
