Flaring has stopped at Chevron Refinery in Richmond

RICHMOND, Calif. (KGO) -- The Chevron Richmond Refinery experienced flaring activity due to an upset at a process unit on Friday, officials said. But a Chevron spokesperson says flaring has stopped now.

This was unplanned, and is under control, said Chevron.

Richmond firefighters say there was no impact outside of the refinery property.

Due to the smoke, a Community Warning System Level 1 was issued. Level 1 is one of the lowest on the CWS scale.

Chevron says, it is working with regulators, and investigating what went wrong.

The refinery is operating normally.

Chevron told ABC7 a "process unit" is a refinery term for one of their big pieces on equipment, "a unit," which helps refine the oil.

Refinery officials say flaring can be used to "relieve pressure during the refining processes and help keep our equipment and plants operating safely."
