California Accidental Release Prevention Program
CalEPA oversees the statewide implementation of the California Accidental Release
Prevention (CalARP) program, which aims to prevent accidental releases of extremely
hazardous substances that pose the greatest risk of immediate harm to the public and
the environment, minimize the damage if releases do occur, and to satisfy community
right-to-know laws.
Program 4 for Refineries
Program 4 (Refineries) Overview
Following the 2012 Chevron Refinery Fire, California created an Interagency Refinery Task Force (IRTF) headed by CalEPA with participation from Department of Industrial Relations and 11 other federal, state, and local agencies and other departments. The purpose of Program 4 is to prevent major incidents at petroleum refineries in order to protect the health and safety of communities and the environment.

Program 4 expands the prevention program requirements for refineries and requires annual process safety performance indicators to be submitted to the CUPA.
