EPA's RMP rollback proposal: what changes for PHA and compliance work as the final rule approaches

The biggest open regulatory question for U.S. process safety programs this year is what survives of the 2024 Risk Management Program amendments. In February, EPA published its proposed rule, “Accidental Release Prevention Requirements: Risk Management Programs Under the Clean Air Act; Common Sense Approach to Chemical Accident Prevention”, which would roll back substantial parts of the 2024 rule. The comment period closed April 10, and EPA has signaled it expects to finalize late in 2026.

What the proposal would change

The stated aim is to reduce compliance burden and re-align RMP with OSHA’s Process Safety Management standard. Key elements of the proposal include scaling back the Safer Technology and Alternatives Analysis (STAA) requirements that the 2024 rule imposed on certain Program 3 facilities, reconsidering third-party compliance audit triggers, narrowing public availability of hazard information, and aligning administrative details — such as hot work permit retention — with OSHA PSM rather than the stricter 2024 provisions.

Legal analyses from Sidley Austin and Holland & Knight frame the proposal as the fourth swing of a regulatory pendulum that has now reversed direction with each administration since 2017.

What it means for hazard analysis work

For facilities covered by both PSM and RMP, the process hazard analysis obligations themselves — five-year revalidation cycles, team composition, documentation — are not the target of the rollback. The practical effects sit around the PHA rather than inside it.

STAA is the clearest example. Facilities that began scoping inherently-safer-technology reviews to meet the 2024 rule now face a choice: complete the work on the current schedule, or wait for the final rule and risk a compressed timeline if the requirement survives in modified form. Deferral is the path many will take, but a hazard-review program built to the stricter standard remains defensible under any outcome — a point worth making in scoping conversations this year.

The audit provisions matter too. If third-party audit triggers are removed or narrowed, some facilities will revert to self-audits, which shifts scrutiny back onto the quality of internal PHA revalidations and their action-item closure records.

Nothing is final until the rule is. EPA’s docket and the Federal Register entry above remain the primary references, and the final rule — expected before year end — will set the compliance landscape for 2027 and beyond.
