CUPA California Accidental Release Prevention (CalARP)

The California Accidental Release Prevention Program (CalARP) is a part of the Orange County CUPA. 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. This program requires any business that handles more than threshold quantities of a Regulated Substance (RS) to develop a Risk Management Plan (RMP). The RMP is implemented by the business to prevent or mitigate releases of regulated substances that could have off-site consequences.

Regulated Substances and their threshold quantities can be found in Title 19, California Code of Regulations, in the following tables:

  • Table 1: Federal list of Toxic Regulated Substances
  • Table 2: Federal list of Flammable Regulated Substances
  • Table 3: California list of Regulated Substances

The Orange County CUPA implements this program for all Orange County cities except for Anaheim and La Habra.
