The purpose of the California Accidental Release Prevention (CalARP) program is to protect the community from the release of extremely hazardous substances into the environment.

CalARP was adapted from the Federal accidental release program established by the Clean Air Act Section 112 (r) and modified to meet California’s needs. The goal of the CalARP Program is to prevent accidental releases of substances that pose the greatest risk of immediate harm to the public and the environment. Environmental Health Division conducts inspections at CalARP facilities and reviews Risk Management Plans.

A CalARP facility is a facility that handles, manufactures, uses, or stores any of the listed regulated substances found in tables 1-3 of the California Code of Regulations, Title 19 Division 2, Chapter 4.5 above threshold quantities. Facilities must submit a Risk Management Plan (RMP) if they handle a Federal Regulated Substance in amounts greater than federal threshold quantities (see Tables 1 & 2) OR if they handle a State Regulated Substance in amounts greater than the state threshold quantities (Table 3).
