Title: Modernization of the Accidental Release Prevention Regulations Under Clean Air Act 

In response to Executive Order 13650, the EPA is considering potential revisions to its Risk Management Program regulations and related programs. The Agency may consider the addition of new accident prevention or emergency response program elements, and/or changes to existing elements, and/or other changes to the existing regulatory provisions.

Statement of Need:

In response to Executive Order 13650, the EPA is considering potential revisions to its Risk Management Program regulations. The Executive Order establishes the Chemical Facility Safety and Security Working Group ("Working Group"), co-chaired by the Secretary of Homeland Security, the Administrator of the EPA, and the Secretary of Labor or their designated representatives at the Assistant Secretary level or higher, and composed of senior representatives of other federal departments, agencies, and offices. The Executive Order requires the Working Group to carry out a number of tasks whose overall goal is to prevent chemical accidents, such as the explosion that occurred at the West Fertilizer facility in West, Texas, on April 17, 2013, which killed 15 people, injured many others, and did extensive damage to the town. Section 6(a)(i) of the Executive Order requires the Working Group to develop options for improved chemical facility safety and security that identify "improvements to existing risk management practices through agency programs, private sector initiatives, Government guidance, outreach, standards, and regulations.' Section 6(c) of Executive Order 13650 requires the Administrator of the EPA to review the RMP Program (RMP).

Summary of the Legal Basis:

Clean Air Act Section 112(r)(7) authorizes the EPA Administrator to promulgate regulations to prevent accidental releases. Section 112(r)(7)(A) authorizes release prevention, detection, and correction requirements that may include a broad range of methods, make distinctions among classes and types of facilities, and may take into consideration other factors, including, but not limited to, size, location, process and substance factors, and response capabilities. Section 112(r)(7)(B) authorizes reasonable regulations and appropriate guidance to provide, to the greatest extent practicable, for the prevention and detection of accidental releases of regulated substances and for response to such releases by the owners or operators of the sources of such releases.


The EPA is considering revisions to the accident prevention, emergency response, recordkeeping, and other provisions in 40 CFR part 68 to address chemical accident risks. The proposed action will contain the EPA's preferred option, as well as alternative regulatory options. The EPA also is considering publishing guidance to address some issues that may be raised in the proposed action.

Anticipated Costs and Benefits:

Costs will include the burden on regulated entities associated with implementing new or revised requirements, including program implementation, training, equipment purchases, and recordkeeping, as applicable. Some costs will also accrue to implementing agencies and local governments, due to enhanced local coordination and recordkeeping requirements. Benefits will result from avoiding the harmful accident consequences to communities and the environment, such as deaths, injuries, and property damage, environmental damage, and from mitigating the effects of releases that may occur.


The proposed action will address the risks associated with accidental releases of listed regulated toxic and flammable substances to the air from stationary sources. Substances regulated under the RMP program include highly toxic and flammable substances that can cause deaths, injuries, property and environmental damage, and other on- and off-site consequences if accidentally released. The proposed action will reduce these risks by making accidental releases less likely, and by mitigating the severity of releases that may occur. The proposed action would not address the risks of non-accidental chemical releases, accidental releases of non-regulated substances, chemicals released to other media, and air releases from mobile sources.
