Oregon Hazardous Waste Rules

On Nov. 17, 2021, DEQ adopted revisions to five sections of Oregon administrative rules governing the treatment, storage and disposal of hazardous waste (Divisions 100, 101, 102, 120 and 135) and related revisions to the Oregon rules governing compliance and enforcement of agency programs (Division 12). In total, the proposed rule amendments modify, update or revise nine elements of Chapter 340 of the Oregon Administrative Rules. These changes will be effective on Jan. 1, 2022

This rulemaking included federal rules adopted by reference, meaning without change from the language as adopted by EPA, and federal rules adopted with Oregon-specific modifications. Five rules required adoption to allow Oregon DEQ to retain its authorization to operate the federal Resource Conservation and Recovery Act (RCRA) hazardous waste program in lieu of EPA in Oregon. Those items are noted in the list below with an asterisk (*). The additional revisions were not required for continued authorization, and will allow Oregon to maintain and implement a protective Hazardous Waste Program reflecting current science and best practices. Visit  the agency rulemaking website for advisory committee meeting and public involvement information, as well as links to the Environmental Quality Commission (EQC) staff report and presentation.

DEQ is currently developing outreach materials for the regulated community such as factsheets and trainings on the adopted rules, which when completed, will be posted here. Below are links to other existing web resources.
