Members of the Richmond, Calif., group Urban Tilth protest before the Chevron town hall meeting at the Richmond Memorial Auditorium in Richmond on Tuesday, Aug. 7, 2012. Investigators are waiting for access to the charred crude oil unit of a Chevron refinery where a fire sent a towering plume of black smoke into San Francisco Bay area skies and pushed gas prices higher along the West Coast. Hundreds of people went to hospitals with respiratory issues during the fire; crowds are lining up to file claims against Chevron. The Richmond refinery produces 16 percent of the region's gasoline supply.
