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. These facilities are required to prepare a Risk Management Plan 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. These facilities are usually cold-storage warehouses, water and wastewater treatment facilities, or industrial chemical manufacturers or dealers.
