Members of the Richmond group Urban Tilth stage a protest before the Chevron town hall meeting at the Richmond Memorial Auditorium in Richmond, Calif., on Tuesday, Aug. 7, 2012. in Richmond, Calif., on Tuesday, Aug. 7, 2012, to pick up a claim form in response to the Chevron refinery fire that impacted the community. 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 at the Richmond refinery that produces 16 percent of the region's daily gasoline supply.
