Chevron Submits Root Cause Analysis Report

Friday, April 12, 2013


The Contra Costa Health Services Hazardous Materials Division has received a final report from Chevron on what Chevron's finding are regarding the root causes of the August 6, 2012 fire at its refinery in Richmond.

The report talks about what Chevron's investigation covered, factors that led to the incident, management systems that failed and the corrective actions that they are taking to address those issues.

Contra Costa Health Services Hazardous Materials is reviewing the report and will continue to work with the U. S. Chemical Safety and Hazard Investigation Board, US EPA, Cal/OSHA, and the Bay Area Air Quality Management District to investigate the circumstances and cause of the refinery fire. When the final reports are issued by these agencies, Contra Costa Health Services Hazardous Materials will determine if there are any additional issues that need to be addressed or actions taken.


The report was received Friday, April 12 and is available to the public online at


The City of Richmond Industrial Safety Ordinance requires facilities that have a major chemical accident or a release to perform an incident investigation including a root cause analysis. The ordinance requires the facilities to submit the final incident investigation and root cause report to Contra Costa Health Services when it is complete. Contra Costa Health Services Hazardous Materials will review the report and submit any follow-up questions and comments to Chevron to address if any are needed.
