By ETHAN SWOPE and HALLIE GOLDEN, Associated PressEL SEGUNDO, Calif. (AP) — A fire broke out at a Chevron oil refinery just outside Los Angeles on Thursday night, sending towering flames into the air that were visible for miles. Residents near the Chevron El Segundo Refinery described feeling a rumble, then they saw the flames. The El Segundo police and fire departments did not immediately comment on the fire, which appeared to have erupted suddenly. El Segundo is a beachside city located about a mile south of Los Angeles International Airport. An air quality index map Friday showed good levels for the Los Angeles area, according to the South Coast Air Quality Management District.
