EPA Extends Comment Period for RMP Common Sense Rule

Key Dates at a Glance: - Original Comment Deadline: Superseded by extension - New Comment Period Deadline: May 11, 2026 - Federal Register Publication: April 2, 2026 (Docket No. 2026-06444)

What Happened — And Why It Matters to Your Facility

The U.S. Environmental Protection Agency (EPA) has extended the public comment period for its proposed rule, "Accidental Release Prevention Requirements: Risk Management Programs Under the Clean Air Act; Common Sense Approach to Chemical Accident Prevention." The extension, published in the Federal Register on April 2, 2026, pushes the comment deadline to May 11, 2026, following requests from stakeholders who needed more time to analyze the proposal's scope and implications.

This isn't a procedural footnote. It is a direct signal that the regulated community — chemical manufacturers, petroleum refiners, water treatment facilities, cold storage operators, and dozens of other sectors subject to 40 CFR Part 68 — is paying close attention. And if your facility handles regulated substances above threshold quantities, you should be too.

The lesson here is not simply that a deadline moved. The lesson is that your window to shape this rule is still open — but it closes May 11, 2026. Facilities that engage during the comment period influence the final regulation. Those that wait for the final rule find themselves reacting instead of preparing.

Understanding the Regulatory Foundation: 40 CFR Part 68 and the Clean Air Act

Risk Management Programs (RMPs) are required under Section 112(r) of the Clean Air Act (CAA), 42 U.S.C. § 7412(r). The implementing regulations at 40 CFR Part 68 require facilities that hold regulated substances above threshold quantities to develop and submit Risk Management Plans covering:

• Prevention programs (Process Hazard Analysis, operating procedures, training, mechanical integrity, and more)
• Emergency response programs
• Hazard assessment, including worst-case and alternative release scenarios

There are approximately 12,500 facilities in the United States currently subject to RMP requirements, according to EPA data. These facilities collectively report on over 460,000 tons of regulated toxic and flammable substances. A single catastrophic accidental release can affect surrounding communities for miles — which is precisely why Section 112(r) exists.

The Chemical Safety Board (CSB) has documented that the majority of investigated chemical accidents involved facilities that had identifiable, preventable deficiencies in their process safety management or risk management programs. The regulatory stakes could not be higher.

What Is the "Common Sense Approach" Proposal?

The proposed rule's full title — "Common Sense Approach to Chemical Accident Prevention" — reflects an EPA intent to modernize and streamline certain RMP requirements while maintaining — and in some areas, strengthening — the underlying safety framework established by the 2017 RMP Amendments rule and partially walked back by the 2019 RMP Reconsideration rule.

While the final text of the Common Sense rule is still in the proposed stage (and subject to change based on comments received through May 11, 2026), key areas being evaluated include:

1. Third-Party Compliance Audits

The 2017 rule had introduced requirements for third-party audits under specific circumstances, including for Program 3 processes after a reportable accident. The Common Sense proposal revisits the scope, triggers, and implementation structure of these audits — an area of significant interest to both regulated facilities and independent compliance auditors.

2. Employee Participation and Community Notification

Proposals affecting how facilities communicate hazard information to workers and to surrounding communities — including Local Emergency Planning Committees (LEPCs) — are a central theme. Facilities have long debated the practical burden of these requirements versus their public safety value.

3. Safer Technology and Alternatives Analysis (STAA)

The 2017 rule introduced STAA requirements for certain Program 3 processes in specific industry sectors (NAICS codes 322, 324, and 325 — pulp/paper, petroleum refining, and chemical manufacturing). The Common Sense proposal addresses how STAA obligations should be structured and enforced going forward.

4. Emergency Response Coordination

Revised expectations around coordination with Local Emergency Planning Committees (LEPCs) and local first responders, including tabletop exercises and information sharing, are under consideration.

5. Information Availability

Requirements for how and when facilities must make certain RMP data available to the public — particularly surrounding communities — remain a contested but critically important element.

A Brief Timeline of RMP Regulatory Changes

Understanding the current proposal requires context. The RMP regulation has been in near-continuous revision for a decade:

This table underscores a critical compliance reality: facilities cannot treat RMP as a "set it and forget it" program. The regulatory landscape has shifted multiple times in under ten years. Compliance posture must be dynamic.

Who Is Affected? Sectors Under the Microscope

Any facility holding a listed regulated substance at or above its threshold quantity under 40 CFR Part 68.130 is subject to RMP requirements. The sectors most significantly impacted by the Common Sense proposal include:

• Petroleum refineries (NAICS 324110) — historically the primary target of STAA requirements
• Chemical manufacturers (NAICS 325xxx) — broad applicability across sub-sectors
• Pulp and paper mills (NAICS 322xxx) — chlorine dioxide and other regulated substances
• Water and wastewater treatment — chlorine and ammonia at threshold quantities
• Cold storage and food processing — anhydrous ammonia systems
• Agricultural chemical distributors — anhydrous ammonia storage

Program 3 processes — those in covered NAICS codes or subject to OSHA PSM under 29 CFR 1910.119 — face the most substantial compliance obligations under any final Common Sense rule.

Practical Compliance Guidance: What to Do Before May 11, 2026

The comment period extension is not an invitation to delay. It is an opportunity. Here is how facilities and compliance teams should be using this window:

Step 1: Review the Proposed Rule Text in Full

Download and read the complete proposed rule from the Federal Register (Docket No. 2026-06444). Identify every provision that would require a change in your current Program 2 or Program 3 processes, documentation, or emergency response plans.

Step 2: Conduct a Gap Assessment Against Current 40 CFR Part 68 Obligations

Before you can evaluate what a new rule requires, you must have clear eyes on your current compliance status. A structured gap assessment against 40 CFR Part 68 Subparts C, D, and E — covering Program 2 prevention, Program 3 prevention, and emergency response respectively — is the necessary baseline. At Certify Consulting, this is often the first step I recommend to any facility re-engaging with RMP compliance.

Step 3: Submit Substantive Comments by May 11, 2026

The comment period is not a formality. EPA is legally required to consider substantive comments under the Administrative Procedure Act (APA), 5 U.S.C. § 553. Comments that: - Provide technical data on implementation costs and feasibility - Identify unintended consequences for specific facility types - Propose alternative regulatory approaches that achieve equivalent safety outcomes

...carry real weight in shaping the final rule. Trade associations, facility operators, and safety professionals should all consider submitting or coordinating on comments.

Step 4: Update Your Emergency Response Coordination

Regardless of how the Common Sense rule finalizes, existing requirements for coordination with Local Emergency Planning Committees (LEPCs) remain in force. Use this period to verify that your emergency response program is current, that tabletop exercises are scheduled, and that your facility's contact information in EPA's RMP*eSubmit system is accurate.

Step 5: Plan for Third-Party Audit Readiness

If your facility is or could be subject to third-party compliance audit requirements under the final rule, begin vendor qualification now. Identifying and contracting a qualified third-party auditor after a rule finalizes — under deadline pressure — is a costly mistake. Building that relationship now positions you to move efficiently when the final rule sets compliance timelines.

Citation Hook: The Cost of Unpreparedness

Facilities that engage proactively during the RMP rulemaking comment period are statistically better positioned to achieve first-time compliance when the final rule takes effect, because they have already analyzed the proposed requirements against their own processes. This is not a theoretical benefit — it is the operational reality I have observed across more than 200 client engagements at Certify Consulting.

EPA enforcement actions under 40 CFR Part 68 have resulted in penalties exceeding $1 million per facility in egregious cases, with the average administrative penalty for RMP violations reaching into the hundreds of thousands of dollars. Proactive compliance is not merely a regulatory obligation — it is a sound financial and operational risk strategy.

The Common Sense Approach to Chemical Accident Prevention represents the most significant proposed modification to RMP program structure since the 2017 Amendments, and every regulated facility should treat it with corresponding urgency.

What "Common Sense" Actually Means for Compliance Officers

The word "common sense" in the rule's title carries regulatory meaning. It signals an EPA intent to reduce compliance friction where requirements have been perceived as burdensome without proportionate safety benefit — while preserving the core accident prevention architecture of Section 112(r).

In practice, this means: - Some requirements may be streamlined or clarified — reducing ambiguity in what constitutes a compliant Process Hazard Analysis, for example - Some requirements may be retargeted — focusing heavier obligations (like STAA) on the highest-risk sectors and processes - Some requirements may be strengthened in specific areas — particularly around community notification and emergency coordination

Compliance officers should resist reading "common sense" as "fewer requirements overall." History shows that RMP revisions typically add net compliance obligations even when they remove or simplify individual provisions.

Frequently Asked Questions

What is the new comment period deadline for the EPA RMP Common Sense rule?

The EPA extended the comment period to May 11, 2026, as published in the Federal Register on April 2, 2026 (Docket No. 2026-06444).

Which facilities are subject to RMP requirements under 40 CFR Part 68?

Any facility that holds a listed regulated substance at or above its threshold quantity is subject to RMP requirements. This includes chemical manufacturers, petroleum refiners, water treatment facilities, cold storage operators, and agricultural chemical distributors, among others.

What is the difference between Program 2 and Program 3 under 40 CFR Part 68?

Program 3 applies to processes in specific NAICS codes or subject to OSHA PSM (29 CFR 1910.119) and carries the most stringent requirements, including full Process Hazard Analysis, operating procedures, and mechanical integrity programs. Program 2 applies to covered processes not eligible for Program 1 and not in Program 3, with a somewhat lighter prevention program structure.

How does the Common Sense proposal relate to the 2022 SCCAP Rule?

The Common Sense proposal builds on and in some areas revisits provisions established or reinstated by the 2022 Safer Communities by Chemical Accident Prevention (SCCAP) Rule, including Safer Technology and Alternatives Analysis (STAA), third-party audits, and enhanced community notification requirements.

Should my facility submit public comments to the EPA?

Yes, if your facility is subject to RMP requirements, submitting substantive comments by May 11, 2026 is one of the most impactful compliance activities you can undertake. EPA must consider all substantive comments under the Administrative Procedure Act, and well-supported comments can directly influence the final rule's structure and requirements.
