Regulatory Alert: EPA published the proposed “Common Sense Approach to Chemical Accident Prevention” rule on February 24, 2026 (Federal Register Document No. 2026-03633), proposing significant revisions to 40 CFR Part 68 — the Risk Management Programs under the Clean Air Act Section 112(r). The public comment deadline has been extended to May 11, 2026. Approximately 11,500 facilities are subject to the RMP rule.
The practical lesson buried inside the regulatory language of EPA’s accidental release prevention requirements: risk management programs under the Clean Air Act; common sense approach to chemical accident prevention is this: do not dismantle what you already built. Facilities that spent 2024 and 2025 implementing the Safer Communities by Chemical Accident Prevention (SCCAP) final rule have real compliance infrastructure in place. The proposed rollbacks reduce some near-term burdens, but this is a proposed rule — not a final one. Until ink is dry on a final rule, existing SCCAP obligations remain in force, and facilities that begin unwinding their compliance programs ahead of schedule are creating enforcement risk, not reducing it.
This article explains exactly what EPA is proposing to change, what is being retained, what the timeline looks like, and how ISO 14001-certified facilities should interpret this proposal in the context of their environmental management systems.
Background: What Triggered the Common Sense Approach Proposal
The 2024 SCCAP final rule, published in March 2024, significantly expanded RMP requirements — introducing Safer Technologies and Alternatives Analysis (STAA) requirements, mandatory third-party compliance audits, enhanced employee participation provisions, natural hazards evaluations, and broader public information-sharing obligations. The rule drew substantial support from environmental justice advocates and significant pushback from regulated industries, particularly petroleum and chemical manufacturers, who argued the compliance costs were disproportionate to safety outcomes.
The current proposal represents a shift in enforcement philosophy. Under the framing of accidental release prevention requirements: risk management programs under the Clean Air Act; common sense approach to reducing regulatory burden, EPA is proposing to walk back several of the most operationally demanding SCCAP provisions while retaining the core accident prevention framework that has been in place since the RMP rule’s inception.
A virtual public hearing was held on March 10, 2026. The comment period originally closed April 10, 2026, but was extended to May 11, 2026 (Federal Register Document No. 2026-06444, published April 2, 2026) following stakeholder requests for additional time. The docket is open at regulations.gov under Docket ID EPA-HQ-OLEM-2025-0313.
Key Proposed Changes Under the Common Sense Approach
1. Safer Technologies and Alternatives Analysis (STAA)
The most sweeping proposed change concerns STAA requirements. Under the SCCAP rule, facilities in NAICS codes 324 (petroleum and coal products manufacturing) and 325 (chemical manufacturing) with Program 3 processes were required to conduct STAA evaluations examining whether safer alternatives to highly hazardous chemicals were technically and economically feasible.
The proposal would:
- Rescind STAA evaluation requirements for all covered processes in NAICS 324 and 325
- Rescind STAA implementation and practicability requirements for Program 3 processes in those same NAICS codes
- Retain STAA requirements only for new Program 3 processes commencing operation three or more years after the effective date of the final rule
For facilities with existing processes already subject to STAA obligations, this represents meaningful relief. For facilities planning new chemical or petroleum processes, the STAA framework will still apply — but with a built-in runway before obligations attach.
2. Third-Party Compliance Audits: Two Options on the Table
The SCCAP rule introduced mandatory third-party audit requirements for covered facilities. The proposal presents two distinct options for public consideration, which is notable — EPA is explicitly soliciting comment on which approach better serves the statutory objective of accident prevention:
- Option A: Complete rescission of all third-party audit requirements
- Option B: Retain third-party audits but limit them to facilities that have experienced two or more RMP-reportable accidents within a five-year period, with a 10-year sunset provision on even those limited requirements
Option B is the more defensible position from an enforcement standpoint — it ties enhanced oversight to demonstrated poor performance. Option A eliminates a tool that, when applied to high-risk processes, has genuine accident prevention value. Facilities with strong compliance records have good reason to prefer Option A; facilities with incident histories may want to weigh in on Option B’s parameters.
3. Public Information Sharing
The SCCAP rule required facilities to provide chemical hazard information upon public request. The proposal removes this obligation, instead directing the public to EPA’s RMP Public Data Tool, which allows county-level searches of facility RMP data. This reduces facility administrative burden but also reduces community access to site-specific chemical hazard information — a change that is likely to attract substantive comments from environmental justice organizations.
4. Employee Participation and Worker Protection Provisions
This is the section of the proposal that will generate the most controversy. The SCCAP rule introduced several worker-protective provisions that the proposal would eliminate:
- Stop work authority: The provision allowing frontline workers to halt operations when they identify an imminent hazard — eliminated entirely under this proposal
- Training requirements on employee participation plans — removed
- Anonymous hazard reporting requirements — eliminated
- Expanded employee consultation on process hazard analysis — removed
The stop work authority provision was among the most practically significant SCCAP requirements. Facilities that invested in stop work culture — training workers, updating SOPs, and building reporting mechanisms — should think carefully before dismantling those programs. The safety case for stop work authority is well-established independently of whether it is federally required. Eliminating it as a regulatory requirement does not eliminate the operational risk it was designed to address.
5. Natural Hazards and Emergency Preparedness
The proposal rescinds standalone natural hazards evaluation requirements added by SCCAP, removes backup power mandates for monitoring equipment, and eliminates documentation requirements for declined safety recommendations. For facilities in regions with significant natural hazard exposure — flood plains, seismic zones, hurricane corridors — this is a case where the regulatory floor is dropping below what sound risk management actually requires.
A facility that drops natural hazards evaluation from its RMP program because the regulation no longer mandates it, then experiences a flood-related chemical release, will face a difficult conversation with both regulators and the public. The accidental release prevention requirements: risk management programs under the Clean Air Act; common sense approach to this issue is to maintain natural hazards evaluation as a voluntary element of your process hazard analysis even if it is no longer mandatory.
6. Administrative Simplifications
Several lower-stakes administrative changes are also proposed:
- Hot work permit retention reduced from three years to completion-only
- Removal of RAGAGEP (Recognized and Generally Accepted Good Engineering Practices) gap analysis requirements
- Reversion of retail facility definitions to pre-2024 standards
- Streamlined community notification documentation requirements
These changes reduce paperwork burden without meaningfully affecting safety outcomes for most facilities. The RAGAGEP gap analysis change is worth monitoring closely — RAGAGEP remains a cornerstone of Process Hazard Analysis and PSM compliance, and reducing documentation requirements does not reduce the underlying technical obligation to operate within recognized engineering standards.
What the Proposal Retains
Before facilities start revising compliance programs, it is essential to understand what this proposal does not change. The following core RMP requirements remain in place and are not proposed for rescission:
- Core RMP development: accident prevention programs, effects identification, emergency response procedures
- Employee participation plans for Program 2 facilities
- 10-year emergency response exercise frequency
- Root cause analysis for incident investigations
- May 10, 2027 compliance deadline for incident investigation provisions — this deadline is retained and applies now
The May 10, 2027 incident investigation deadline deserves specific attention. Facilities should not interpret the rollback proposal as a general reprieve. That deadline is active and facilities need to have compliant incident investigation procedures in place by that date regardless of how the broader proposal resolves.

Economic Context
EPA estimates the proposed changes would generate annualized savings of $234.7 to $240.3 million at a 3% discount rate. For regulated industries, that is a meaningful number — particularly for smaller chemical manufacturers operating on thin margins. The economic argument for the proposal is straightforward: SCCAP compliance costs were front-loaded and capital-intensive, and the proposal shifts burden reduction in a direction that does not touch the fundamental accident prevention architecture of Part 68.
Whether those savings are worth the tradeoffs in worker protection and community hazard transparency is precisely the kind of value judgment the public comment process is designed to surface.
What This Means for Your Facility: Practical Guidance
Do Not Prematurely Unwind SCCAP Compliance Programs
This is a proposed rule. The SCCAP final rule from March 2024 remains the operative regulatory requirement until a new final rule is published and effective. Facilities that begin eliminating STAA documentation, dismantling third-party audit programs, or rolling back employee participation provisions before a final rule is in place are exposing themselves to enforcement actions under the current rule. The compliance posture right now is: maintain SCCAP compliance, monitor the rulemaking, and plan for possible changes.
Review Your Legal Register and Flag the Uncertainty
ISO 14001 clause 6.1.3 requires facilities to identify and have access to their applicable legal and other requirements. A pending proposed rulemaking that may substantially change your RMP obligations is exactly the kind of compliance uncertainty that should be documented in your legal register. Flag the SCCAP provisions under review, note the comment deadline and the retained May 2027 deadline, and assign a responsible party to monitor the rulemaking through to final rule publication.
Assess Which SCCAP Provisions You Have Already Implemented
Facilities that have already completed STAA evaluations, established stop work authority programs, or built anonymous hazard reporting channels have invested real resources in those systems. Even if those requirements are ultimately rolled back, the underlying safety value does not disappear. Conduct an internal review: which SCCAP provisions did you implement, what did they cost, what safety benefit are they delivering, and which ones would you choose to retain voluntarily even if the regulatory mandate is removed?
Submit Substantive Comments by May 11, 2026
The comment process is the appropriate mechanism for facilities to influence the final rule. If you have data on STAA compliance costs, documented experiences with third-party audits, or operational perspectives on stop work authority, those are exactly the kinds of substantive comments that inform final rulemaking decisions. Comments should be submitted through regulations.gov, Docket ID EPA-HQ-OLEM-2025-0313. Vague support or opposition is less useful than specific operational data and reasoned arguments.
Maintain Natural Hazards Evaluation Regardless of Regulatory Outcome
Natural hazards evaluation belongs in your process hazard analysis independent of whether 40 CFR Part 68 requires it. A facility in a flood zone, earthquake corridor, or hurricane path that removes natural hazards from its PHA because the regulatory requirement was rescinded has made a risk management decision — not just a compliance decision. ISO 14001 clause 6.1.1 requires identification of risks and opportunities associated with environmental conditions, including natural events, that can affect your organization. That obligation does not change based on where the RMP floor sits.
How ISO 14001 Certification Intersects with RMP Compliance
Under the proposed rule, ISO 14001-certified facilities have one specific, limited benefit: the ability to inform the implementing agency of their certification status, which the agency has discretion to consider when making decisions about third-party audit requirements. This is not an automatic exemption. The proposal does not grant ISO 14001 certification a formal waiver from any RMP provision — it simply places certification status in the same category of information that implementing agencies may weigh when exercising discretionary authority.
That said, ISO 14001 certification is a genuine signal of EMS maturity that goes beyond the RMP framework. Facilities operating under a robust ISO 14001-aligned environmental management system are structurally better positioned to comply with RMP requirements because they already have:
- A functioning legal and regulatory requirements register (clause 6.1.3) that captures and tracks Part 68 obligations
- Documented operational controls (clause 8.1) for managing significant environmental aspects — including chemical release risks
- Emergency preparedness and response procedures (clause 8.2) that align with RMP emergency response program requirements
- An internal audit process (clause 9.2) that overlaps significantly with the compliance audit function the SCCAP rule mandated via third parties
- Management review processes (clause 9.3) that ensure compliance status is visible at the leadership level
The accidental release prevention requirements: risk management programs under the Clean Air Act; common sense approach to integrated compliance management is exactly this: build an EMS that makes regulatory compliance a structural output rather than a periodic exercise. Facilities that run strong ISO 14001 systems routinely find that their RMP compliance gaps are smaller, their incident rates are lower, and their audit findings are less severe than industry peers operating without a formal EMS framework.
If your facility is not yet ISO 14001 certified, the current regulatory uncertainty is actually a compelling reason to pursue it. Certification creates an independent, auditable record of your environmental management rigor — exactly the kind of credential that carries weight with implementing agencies making discretionary judgments about audit requirements.
Looking Ahead: What to Watch
The comment period closes May 11, 2026. After that, EPA will review comments and publish a final rule — a process that typically takes 12 to 24 months for rulemakings of this scope and controversy. Legal challenges to either the proposed rollback or the eventual final rule are probable, given the organized advocacy communities on both sides of the SCCAP debate.
For compliance managers, the watch items are:
- Whether the final rule adopts Option A or Option B on third-party audits — or something entirely different based on public comment
- How the STAA rescission is scoped in the final rule, particularly for facilities with mixed NAICS codes
- Whether any litigation delays the effective date of the final rule, which would extend the period during which SCCAP requirements remain operative
- How implementing agencies exercise their newly expanded discretion under either audit option
The May 10, 2027 incident investigation compliance deadline runs independently of all of this. That date is not proposed for change. Mark it now.
The Bottom Line
EPA’s proposed accidental release prevention requirements: risk management programs under the Clean Air Act; common sense approach to chemical accident prevention reduces near-term compliance burdens for petroleum and chemical manufacturing facilities, particularly on STAA and third-party audit requirements. But it is a proposal, not a final rule, and the gap between the two can be substantial — in content, timing, and legal durability.
Facilities that respond to this proposal with disciplined patience — maintaining current SCCAP compliance, monitoring the rulemaking through its public comment process, and using the comment period to put operational data on the record — are managing this transition correctly. Facilities that treat the proposed rule as the new operating baseline are taking a regulatory risk that the compliance calendar does not currently support.
The retained May 10, 2027 incident investigation deadline, the ongoing core RMP obligations, and the active SCCAP requirements all demand continued attention regardless of how the proposal resolves. A strong ISO 14001-aligned EMS is the structural foundation that makes managing this kind of regulatory complexity tractable over time.
