The EPA is withdrawing its proposed rule entitled "Definition of Hazardous Waste Applicable to Corrective Action for Releases From Solid Waste Management Units." The Agency issued the proposed rule to: amend the regulatory definition of hazardous waste applicable to corrective action to address releases from solid waste management units at hazardous waste treatment, storage, and disposal facilities permitted under the RCRA and make conforming amendments related to the definition amendment; and add the statutory corrective action authorities to the section of the regulations that provides notice that the statutory definitions, rather than the regulatory definitions, apply to certain sections of the statute. The Agency has concluded that the proposed revisions to the existing regulations would have complicated, rather than contributed to, efficient implementation of corrective action. For those reasons EPA has determined that withdrawal is appropriate. The proposed rule published on 8 February 2024 (89 FR 8598) is withdrawn as of 8 May 2026.
