Compliance Alert: The U.S. EPA has extended the public comment period for its proposed "Common Sense Approach to Chemical Accident Prevention" rule to May 11, 2026. If your facility operates a Risk Management Program under the Clean Air Act, this is a regulatory development you cannot afford to ignore.
What Is Happening — and Why It Matters to Your Facility
On April 2, 2026, the U.S. Environmental Protection Agency published a notice in the Federal Register (Docket No. 2026-06444) extending the public comment period for the proposed rule titled "Accidental Release Prevention Requirements: Risk Management Programs Under the Clean Air Act; Common Sense Approach to Chemical Accident Prevention." The extension was granted in direct response to stakeholder requests for more time to review and respond to a complex, far-reaching proposal.
The lesson here is not just administrative. An extended comment period is a rare and valuable window for regulated facilities to shape the final rule — and a strong signal that the EPA is proposing changes substantial enough that industry, environmental advocates, and the public all need more time to digest them.
If you operate a Program 2 or Program 3 facility under 40 CFR Part 68 — whether you handle ammonia, chlorine, flammable gases, or any of the 140+ regulated substances under the Clean Air Act's RMP provisions — this proposed rulemaking directly affects your compliance obligations, your process hazard analysis (PHA) requirements, and potentially your emergency response planning.
Background: What Is the RMP Rule?
The Risk Management Program (RMP) rule, codified at 40 CFR Part 68, was established under Section 112(r) of the Clean Air Act (42 U.S.C. § 7412(r)). It requires facilities that use extremely hazardous substances above threshold quantities to develop and implement risk management programs designed to prevent accidental chemical releases and minimize their consequences.
Facilities subject to 40 CFR Part 68 must:
- Register their RMP with the EPA
- Conduct hazard assessments, including worst-case and alternative release scenario analyses
- Implement prevention programs, including PHAs, operating procedures, training, and mechanical integrity protocols
- Develop emergency response programs coordinated with Local Emergency Planning Committees (LEPCs)
- Submit RMP plans to the EPA every five years or upon significant process changes
According to the EPA, there are approximately 12,000 facilities in the United States currently subject to RMP requirements. These include chemical manufacturers, water and wastewater treatment plants, oil refineries, cold storage facilities, and agricultural operations.
What the Proposed Rule Would Change: "Common Sense Approach to Chemical Accident Prevention"
The proposed rule, which the EPA has branded a "Common Sense Approach to Chemical Accident Prevention," represents a significant recalibration of the RMP framework. While the full scope of the proposed changes will only be finalized after the comment period closes and the EPA processes public input, the proposal signals movement in several critical areas:
1. Streamlining and Modernizing Compliance Requirements
The EPA has indicated that the rulemaking aims to reduce regulatory burden on smaller facilities while maintaining — and in some areas strengthening — core accident prevention requirements. This dual objective reflects a tension that stakeholders will want to address in comments: simplification must not come at the cost of chemical safety.
2. Revisiting the 2017 and 2019 RMP Rule History
This proposed rule exists within a contentious regulatory history. The Obama-era 2017 RMP Amendments (effective March 21, 2017) significantly expanded requirements, including: - Safer technology and alternatives analysis (STAA) for Program 3 facilities - Third-party compliance audits - Enhanced incident investigation requirements - Improved public disclosure of chemical hazard information
The Trump administration's 2019 RMP Reconsideration Rule then rolled back many of these provisions. Courts subsequently vacated portions of the 2019 rule. The Biden administration's 2024 RMP Amendments (effective May 10, 2024, with compliance dates phased through 2027) restored and expanded upon many of the 2017 provisions.
The current proposed rule under the new administration represents yet another potential shift. Facilities must track which version of the rule governs their current obligations and prepare for the possibility that final rulemaking will introduce a new compliance timeline.
3. Key Areas Under Proposed Revision
| Requirement Area | Current Rule Status (2024 Amendments) | Proposed Direction |
|---|---|---|
| Safer Technology & Alternatives Analysis (STAA) | Required for Program 3 NAICS 324/325 facilities | Under review for potential modification |
| Third-Party Audits | Required following incidents or compliance orders | Scope and triggers under reconsideration |
| Public Information Disclosure | Enhanced requirements added in 2024 | Potential streamlining under consideration |
| Emergency Response Coordination | Active coordination with LEPCs required | Maintained; possible clarification |
| Incident Investigation | Root cause analysis required | Modernization of documentation requirements proposed |
| Compliance Audit Frequency | Every 3 years (Program 2 & 3) | Timeline adjustments under discussion |
Note: The specific provisions under revision will be confirmed once the EPA publishes the full proposed rule text and after the comment period closes on May 11, 2026.
The Extended Comment Deadline: Key Dates at a Glance
| Milestone | Date |
|---|---|
| Proposed Rule Published in Federal Register | April 2, 2026 |
| Original Comment Period Deadline | [Prior to extension] |
| Extended Comment Period Deadline | May 11, 2026 |
| Expected Final Rule Publication | TBD — monitor EPA docket |
| Anticipated Compliance Effective Date | TBD — subject to final rule |
The May 11, 2026 comment deadline is firm. Comments submitted after this date will not be considered part of the official rulemaking record.
Why You Should Submit a Comment — Even If You Think It Won't Matter
Many compliance professionals dismiss the public comment process as performative. That would be a mistake here. The administrative record created during the comment period directly constrains the EPA's final rule. Courts have repeatedly vacated federal rules where agencies failed to adequately respond to substantive comments — the 2019 RMP Reconsideration Rule itself was partially vacated for this reason.
A well-constructed comment from your facility or industry association can:
- Create a record that requires the EPA to explain its reasoning on issues important to your operations
- Provide real-world data (incident rates, compliance costs, operational constraints) that the agency may lack
- Support legal challenges if the final rule is arbitrary or not supported by the record
- Signal to the EPA which provisions create disproportionate burden on specific industries
If you operate in food and beverage cold storage (ammonia refrigeration), water treatment (chlorine handling), or petroleum refining, your facility type is specifically mentioned in prior RMP rulemaking preambles as a target population. Your operational realities should be in the record.
Practical Compliance Guidance: What to Do Before May 11, 2026
Regardless of how the proposed rule evolves, regulated facilities should take the following steps now:
Step 1: Confirm Your Current Program Level and Compliance Status
Determine whether your facility is classified as Program 1, 2, or 3 under 40 CFR Part 68. Program 3 facilities face the most stringent requirements, including PHAs, management of change (MOC) procedures, and — under the 2024 amendments — STAA requirements for certain NAICS codes. Facilities that have not updated their RMP submissions since before 2024 may already be out of compliance with the current rule.
Step 2: Review the 2024 RMP Amendment Compliance Deadlines That Are Already in Effect
The 2024 RMP Amendments introduced phased compliance dates. Key deadlines that are already active or imminent include:
- Employee participation enhancements — effective May 10, 2024
- STAA for Program 3 NAICS 324/325 — compliance required by May 10, 2027
- Third-party audit requirements — triggered upon qualifying incident or compliance order
- Information disclosure updates — coordination with LEPCs within 60 days of significant process changes
Do not wait for the proposed rule to be finalized before addressing obligations under the existing 2024 rule.
Step 3: Engage Legal and Technical Counsel to Draft a Comment
If your facility is materially impacted by the proposed changes, engage qualified environmental regulatory counsel and process safety engineers to prepare a comment. Comments should be:
- Specific — reference specific proposed regulatory text by section
- Data-driven — include cost estimates, incident data, or operational parameters
- Constructive — propose alternative regulatory approaches where you oppose a provision
Generic or boilerplate comments carry little weight in the rulemaking record.
Step 4: Conduct or Update Your Process Hazard Analysis
Whether or not the proposed rule changes PHA requirements, your PHA is the foundation of your entire RMP. If your most recent PHA is more than 3 years old without revalidation, you are likely out of compliance today. A current, documented PHA also positions your facility favorably in any EPA inspection or audit triggered by the new rule's enforcement provisions.
Step 5: Integrate RMP Compliance into Your Environmental Management System
Facilities with a certified ISO 14001 Environmental Management System (EMS) have a structural advantage in RMP compliance. ISO 14001:2015 clause 6.1.1 requires organizations to identify environmental aspects with significant impacts — a requirement that maps directly onto the RMP's hazard assessment requirements. Clause 8.1 (Operational Control) and clause 8.2 (Emergency Preparedness and Response) align with the RMP's prevention program and emergency response planning requirements respectively.
An ISO 14001-certified EMS does not substitute for RMP compliance, but it creates the systematic framework — documented procedures, management review, corrective action processes — that makes RMP compliance sustainable rather than episodic. Facilities operating without a formal EMS are more likely to experience the compliance gaps that trigger EPA enforcement actions.

The Enforcement Reality: Why Chemical Facilities Cannot Afford Gaps
The EPA's enforcement of RMP requirements has intensified in recent years. According to EPA enforcement data, RMP violations are among the most commonly cited findings in Clean Air Act Section 112(r) inspections, with failure to conduct adequate PHAs and inadequate mechanical integrity programs representing the top two deficiency categories.
Penalties for RMP violations can reach $70,117 per day per violation under current Clean Air Act penalty authority (adjusted for inflation under 40 CFR Part 19). Facilities that experience a reportable accidental release without a compliant RMP in place face compounded liability: civil penalties, potential criminal referral, and reputational harm that no compliance budget can fully offset.
The average cost of a major chemical accident at an RMP-regulated facility exceeds $10 million when accounting for emergency response, regulatory penalties, litigation, and operational downtime — a figure that dwarfs the cost of maintaining a robust prevention program.
What ISO 14001 Practitioners Need to Know
As a consultant who has guided 200+ organizations through environmental management system certification at Certify Consulting, I've seen a consistent pattern: facilities with robust, audited EMSs are dramatically better positioned for regulatory inspections — including RMP audits — than those managing compliance in functional silos.
The proposed RMP rule's emphasis on systematic prevention, documented procedures, management accountability, and continual improvement mirrors the architecture of ISO 14001:2015. If you're already certified, you have the infrastructure. The gap, for most facilities, is in explicitly mapping your ISO 14001 procedures to specific 40 CFR Part 68 requirements so that both your EMS auditor and an EPA inspector can trace compliance evidence through the same documented system.
If you're not yet ISO 14001 certified and you operate a Program 2 or Program 3 facility, the combination of the 2024 RMP rule compliance deadlines and this new proposed rulemaking is a compelling case for building that system now — not after the final rule is published.

Frequently Asked Questions
Does the extended comment period delay my current RMP compliance obligations?
No. The comment period extension applies only to the proposed rulemaking process. All compliance obligations under the existing 2024 RMP Amendments (40 CFR Part 68) remain in full effect. If your facility has upcoming compliance deadlines under the 2024 rule, those are unaffected by this notice.
Who should submit comments to the EPA on this proposed rule?
Any facility regulated under 40 CFR Part 68, industry trade associations, local emergency planning committees, environmental organizations, and state environmental agencies have standing to submit comments. You do not need to be a large corporation — small facilities with practical compliance experience provide some of the most useful data points in rulemaking records.
How do I submit a comment before the May 11, 2026 deadline?
Comments must be submitted through the federal rulemaking portal at regulations.gov, referencing Docket ID No. EPA-HQ-OEM-[docket number]. Confirm the specific docket number on the Federal Register notice (2026-06444) before submitting. Include your facility type, NAICS code, and the specific provisions your comment addresses.
Will this proposed rule replace the 2024 RMP Amendments entirely?
Not necessarily. Rulemaking can result in targeted modifications, full replacement, or withdrawal of the proposal. Until a final rule is published in the Federal Register, the 2024 RMP Amendments govern compliance. Facilities should plan compliance around the existing rule while monitoring the rulemaking docket for updates.
How does ISO 14001 certification relate to RMP compliance?
ISO 14001:2015 provides a systematic environmental management framework that structurally supports RMP compliance. Clause 6.1.1 (environmental aspects and risk assessment), clause 8.1 (operational controls), and clause 8.2 (emergency preparedness and response) directly parallel 40 CFR Part 68 prevention program and emergency response requirements. Certification does not substitute for RMP compliance, but it creates auditable, documented systems that demonstrate compliance intent and operational diligence.
