California Accidental Release Prevention Program

Overview

The California Accidental Release Prevention (CalARP) program was implemented on January 1, 1997, and replaces the former California Risk Management and Prevention Program (RMPP). The purpose of the CalARP program is to prevent accidental releases of substances that can cause serious harm to the public and the environment, and to minimize the damage if releases do occur.

CalARP requires certain facilities (referred to as “stationary sources”) which handle, manufacture, use, or store any regulated substances above threshold quantities to take actions to proactively prevent and prepare for accidental releases. Facilities subject to CalARP requirements must submit a Risk Management Plan (RMP).

The California Environmental Protection Agency (CalEPA) oversees the implementation of the CalARP program at the state level, while this Department implements the CalARP program in the City.
