Imperial CUPA California Accidental Release Prevention Program
The purpose of this program is to prevent the accidental releases of hazardous chemicals at a stationary source, which can pose a significant hazard to the community. The CalARP program statutes are in Chapter 6.95, Article 2 of the California Health and Safety Code. The regulations for this program are in the California Code of Regulations (CCR), Title 19, Division II, Section 2700, et seq.
CalARP requires all facilities handling regulated substances above threshold quantities to file a CalARP registration form.These facilities are required to prepare a Risk Management Plan (RMP) describing current and past practices and releases, what the impact of releases may be, and what they do or plan to do to prevent releases and minimize their impact if one occurs. Most CalARP / RMP facilities handle large quantities of chemicals such as ammonia, chlorine, sulfur dioxide, butane, or fumigants.
A Risk Management Plan requires offsite consequence analysis, evaluation of process hazards, and implementation of an accidental release prevention program. The regulated facilities are required to submit a Risk Management Plan containing the followings:
- A facility hazard assessment that identifies the potential effects of an evaluation of the worst case scenario.
- A release prevention program that includes prescribed maintenance of systems containing extremely hazardous materials, monitoring, and training for operators and maintenance personnel, and,
- An emergency response program addressing emergency response training for employees and procedures for informing the public and response agencies in the event of a release.
Facilities with new or modified covered processes are required to prepare Risk Management Plans before operations commence. They were required to file a RMP with the Federal Environmental Protection Agency and the CUPA and implement their prevention programs by the federal deadline of June 21, 1999. 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. Facilities working on the five-year anniversary Risk Management Plan (RMP) update should be aware that EPA has proposed regulatory and technical changes to RMP submissions to be effective early 2004.
