California Accidental Release Prevention


Environmental Health is responsible for managing the California Accidental Release Prevention (Cal ARP) program. Cal ARP covers businesses that handle one or more regulated substances on a specified list that are more than the threshold quantity.

The most common regulated substances in Santa Cruz County include anhydrous ammonia, gaseous chlorine and certain pesticides. Covered facilities must develop a risk management plan (RMP) and implement an accidental release prevention program. The RMP includes safety information, a hazard review, operating procedures, training, maintenance, compliance audits and incident investigation.

The purpose of this program is to minimize the risk of an off-site release of a regulated substance that would adversely impact the surrounding community.
