The Sacramento County Environmental Management Department, Environmental Compliance Division is the administering agency responsible for implementing the California Accidental Release Prevention (CalARP) program in Sacramento County.

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. The Environmental Compliance 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) AND have been determined to present a significant likelihood of a regulated substance accident risk.
