We just received this photo from a Claycordian in Martinez, who says she saw this black smoke, which came from the area of the Shell Refinery in Martinez.
As we reported just a little while ago, authorities are investigating a strong smell of natural gas at the Shell Refinery in Martinez. They say there is no shelter-in-place, but say anybody with pre-existing respiratory issues such as asthma should avoid the area or stay indoors.
The Contra Costa Health Department says two puffs of black smoke were sent into the air from a flare at the Shell Refinery earlier today.
