The U.S. Environmental Protection Agency seeks to revise its accidental release prevention requirements of Risk Management Programs (RMP) under the Clean Air Act, Section 112(r)(7).

According to EPA, the proposed revisions are intended to modernize its chemical safety and security regulations, guidance and policies, and they are required under Executive Order 13650. The order directs the federal government to carry out a number of tasks intended to prevent chemical accidents such as the explosion in West, Texas, on April 17, 2013.

The proposed revisions include several changes to the accident prevention program requirements. They include:

  • An additional requirement for the process hazard analysis (PHA) required for Program 3 processes.
  • Enhancements to the emergency preparedness requirements.
  • Increased public availability of chemical hazard information.
  • Several other changes to certain regulatory definitions and data elements submitted in the RMPs.
