A nine-plus hour fire at the Chevron El Segundo Refinery has left motorists anticipating higher prices with the facility closed for cleanup and repairs while nearby were largely moving on after being rattled in the hours after an explosion sparked the flames, observers said Saturday. The South Coast Air Quality Management District said pollution levels were elevated near the refinery overnight, but had settled by Friday morning. California’s largest refinery is Marathon Oil Corp.’s Los Angeles Refinery in nearby Carson. “Following Chevron’s active response along with support from the cities of El Segundo and Manhattan Beach emergency services, the fire is now out.
