The EPA’s RMP Reconsideration Final Rule Fact Sheet has been in effect for a couple of years. Annual notification drills in coordination with emergency responders and field exercises must be done and compliance is required by December 19, 2024. Tabletop exercises are due by December 21, 2026. The scope and frequencies of these notifications and exercises are written in the regulations. Additional regulatory changes to the RMP Program may be implemented in the near future with the EPA’s Risk Management Program Safer Communities by Chemical Accident Prevention Proposed Rule, signed on August 18, 2022. The rule proposes additional changes to the RMP Program, and the public comment period closed on October 31, 2022. IIAR submitted comments, taking input from members of the organization and in partnership with other industry organizations, to provide input to the EPA’s ruling.

IIAR continues to monitor government programs that impact the use of all refrigerants. IIAR also continues to make government agencies aware of the benefits of ammonia and other natural refrigerants for their viability and potential for future use.
