Learn about the EPA’s Risk Management Program v. OSHA’s Process Safety Management Plan
Do you have crossover plan development duties under Process Safety Management (PSM) and the Risk Management Program? Read this article to get the basic differences between each requirement and what you should know. Even if your workplace only follows or requires one type of program/plan, this article will ensure you have key information to understand when one is required over the other.
It is crucial for all employees who may be impacted to be aware of the hazards associated with storing, mixing, or processing chemicals. They should clearly understand how each process works and identify when equipment malfunctions or operates outside safe limits.
According to quarterly raw data releases from the Chemical Safety and Hazard Investigation Board (CSB), in fiscal year 2023, reportable incidents increased by 51% compared to the previous year. Incidents involving serious injuries increased by 11%, and there was a significant 78% increase in chemical accidents resulting in fatalities.
Employees should know the appropriate response procedures and who to contact for assistance in case of equipment malfunction, an emergency, or a chemical release.
PSM
The Occupational Safety and Health Administration’s (OSHA’s) Process Safety Management (PSM) standard applies to processes that involve a certain quantity of chemicals listed in Appendix A of the PSM standard. It also applies to processes that contain a specific amount of flammable gases or liquids with a low flashpoint.
Additionally, the PSM standard covers the manufacture of explosives or pyrotechnics. However, there are exceptions to the standard, such as retail facilities, certain fuel usage, storage of flammable liquids in atmospheric tanks, oil or gas well operations, and normally unoccupied remote facilities. As of June 2024, OSHA continues rulemaking efforts to update its PSM standard.
RMP
The Environmental Protection Agency (EPA) has established regulations and guidelines for preventing chemical incidents at facilities that handle hazardous substances. These regulations are outlined in the Risk Management Program (RMP) rule, which can be found in 40 CFR Part 68.
The RMP rule requires facilities to provide specific information that aids local fire, police, and emergency response teams in preparing for and addressing chemical emergencies. Additionally, making RMPs accessible to the public promotes communication and awareness, ultimately enhancing incident prevention and emergency response efforts at the local level.
RMP v. PSM
The Clean Air Act establishes the obligation to create RMPs and the requirement for PSM. RMPs' main objective is to safeguard the surrounding population outside of a facility, while PSM focuses on protecting employees within the facility.
The EPA is responsible for administering and enforcing the RMP rule, whereas OSHA oversees the administration and enforcement of PSM.
Under the RMP rule, facilities must submit plans to the EPA and local emergency responders to ensure they are informed about potential environmental and exposure risks when responding to an incident. Apart from this distinction, the standards for RMPs and PSM are nearly identical.
Does your workplace need to submit an RMP?
Suppose a facility utilizes a quantity of any chemical listed in the List of Regulated Substances (40 CFR 68.130) that exceeds a specific threshold. In that case, they must adhere to the Risk Management Plan (RMP) regulations established by the Environmental Protection Agency (EPA).
These regulations require that the owners or operators of these facilities implement a risk management program and submit an RMP to the EPA. It is important to note that RMPs must be reviewed, updated, and resubmitted every five years to ensure compliance.
What chemicals must be reported
Chemicals listed on the EPA's RMP List of Regulated Substances (40 CFR 68.130) and present in quantities exceeding a specific threshold must be reported under the Risk Management Program (RMP). It is worth noting that several of the chemicals included in this list can also be found on OSHA's List of Highly Hazardous Chemicals (29 CFR 1910.119 Appendix A).
In closing, employers should also know that the RMP and PSM plans require employers to cover certain elements. Creating and maintaining each of these programs/plans requires adequate resources, facility-specific information, and internal and external checks and balances, ensuring workers and/or the community are properly notified about key information and protected in the event of an accidental release.
Key to Remember
The Clean Air Act establishes RMPs to protect the community and PSM to safeguard employees. Employers should understand if they have crossover duties that must be followed in their workplace.
