California Accidental Release Program (CalARP)

Facilities with new or modified covered processes are required to prepare Risk Management Plans and implement accident prevention programs before operations commence. The risks related to regulated substances may also trigger additional studies or mitigations for new facilities seeking land use approval. Those facilities that have submitted a RMP previously are required to submit a revised RMP no later than 5 years after the initial RMP submission.

For more information about the San Bernardino County CUPA CalAPR submission process, please contact the CalARP subject matter specialist in our office.

The California Accidental Release Prevention Program regulations and other Statewide information regarding CalARP are located at the web site of the California Office of Emergency Services. Extensive guidance is available from US EPA’s web site and these tools are useful for stationary sources preparing RMPs whether they are subject to the federal rule or not.

A Risk Management Plan requires offsite consequence analysis, evaluation of process hazards, and implementation of an accidental release prevention program. Stationary sources are required to coordinate the development and documentation of the prevention program with the CUPA. The most common regulated substances found in San Bernardino County that require a RMP are chlorine, nitric acid, ammonium hydroxide, and anhydrous ammonia. There are hundreds of other chemicals that may require the RMP at specified threshold quantities. These specific chemicals and their threshold quantities are listed in the CalARP regulations found in CCR Title 19.
