Flaring activity at Chevron Richmond Refinery sends off huge plume of black smoke

RICHMOND, Calif. (KGO) -- A huge plume of black smoke could be seen rising from flaring activity at the Chevron Richmond Refinery on Tuesday afternoon.

Around 2:40 p.m., Chevron notified Contra Costa County that flaring was happening at the plant due to an "unplanned upset in one of its systems" causing the release of Sulfur Dioxide.
