RODEO -- A steam-operated turbine at the Phillips 66 refinery in Rodeo briefly lost power and caused a smoky flare, prompting a public safety alert Monday afternoon.

The warning was issued at 1:04 and canceled by 1:15 p.m., according to Paul Andrews, a hazardous materials specialist for Contra Costa County. The refinery is located near Interstate 80, where smoke was visible Monday afternoon.

A health warning was issued due to soot from the refinery blowing into Rodeo and nearby Crockett that could affect people with asthma and other respiratory conditions.

The cause of the incident is still under investigation.

Built in 1896, the Phillips 66 refinery processes more than 80,000 barrels of crude oil a day.
