 California Accidental Release Prevention (CalARP) Program

The goal of the CalARP program is to reduce the likelihood, and severity of consequences, of extremely hazardous materials releases. Any business which handles Regulated Substances (including Federally listed Extremely Hazardous Substances and State listed Acutely Hazardous Materials) above reportable thresholds is required to prepare a Risk Management Plan. The Risk Management Plan describes current and best practices for releases, what the impact of releases may be, and what the business does or plans to do to prevent releases and minimize the impact of a release if one occurs.

Additional information about the CalARP program and regulations is available at the State of California Office of Emergency Services website. Go to and navigate to the Hazardous Materials page.
