Comparison of the EPA Risk Management Program with
OSHA's Process Safety Management Program
The Environmental Protection Agency's (EPA) "Risk Management Programs for Chemical
Accidental Release Prevention" (40 CFR Part 68) adds significant new requirements beyond
those in the Occupational Safety and Health Administration (OSHA), "Process Safety
Management of Highly Hazardous Chemicals" (29 CFR 1910.119). In addition, the chemical list
and threshold quantities for the EPA rule differ somewhat from those in the OSHA rule and may
well result in a facility needing to expand their risk management program to other portions of the
facility as shown in Appendix A.

Preparation of written risk management plans to document the risk management program.
EPA makes the plans available to the public, State and local emergency planning officials
and the Chemical Safety and Hazard Investigation Board. Response actions have to be
coordinated with local emergency planning and response agencies.

The key differences between the OSHA rule on process safety management (PSM) and the EPA
Risk Management Program (RMP) are discussed in the following sections.
Risk Management Program
A risk management plan must be developed and implemented by all facilities that manufacture,
process, use, store, or handle regulated substances to provide an integrated approach to
identifying and managing the hazards posed by the regulated substances. The RMP consists of
three major parts (a) a hazard assessment, (b) a prevention program, and (c) an emergency
EPA considers critical its requirement for the owner or operator of a facility to define its
management system and name the person or position responsible for the program. The facility
owner or operator also would be required to document the results of the risk management
program(s) in the risk management plan. Facilities will be required to maintain onsite
documentation of the implementation of the risk management plan.
EPA requires a risk management plan that summarizes the program elements because the
information of most use to the public and local agencies will be related to the hazard assessment
and consequence analysis.
