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. Program 4 CalARP stationary sources are subject to further requirements under 19 CCR Article 7.
NOTE: Owners or operators of Program 4 facilities are required to submit a report to CalEPA and the UPA every year on June 30 for the period from January 1 to December 31 of the prior year containing the Process Safety Performance Indicator information listed in 19 CCR Section 5110.19(h)(1) subsections (A) through (E).
The completed Annual Process Safety Performance Indicator Form must be submitted every year on June 30 for the period from January 1 to December 31 of the prior year to both:
- CalEPA’s CalARP Unit at CalARP@calepa.ca.gov
