Chevron officials say the flaring event was caused by a power disruption to part of the refinery. A thorough investigation will be conducted to determine the cause.
Due to the visibility of smoke, Chevron says a Community Warning System (CWS) Level 1 was issued in place to keep residents informed. Level 1 is one of the lowest on the CWS scale.
Bay Area Air District tweeted high temperatures are allowing the smoke plume to move up into the atmosphere. They advise local residents to follow instructions from authorities.
