Richmond and Chevron Choose Fork in the Road.

Competing tours offer two very distinct ways to see the industrial city of Richmond in the East Bay. A ''Toxic Tour,'' led by an environmental justice group, circles Chevron's Richmond Refinery and passes through what the group's local members call the city's ''petrochemical corridor.'' On Chevron's newly offered refinery tours, visitors don hard hats and safety glasses and hear of strict emission standards, exemplary safety records and jobs, jobs, jobs. [ABSTRACT FROM PUBLISHER]
