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.
