Authorities are still trying to determine the cause of a fire at the Chevron refinery in El Segundo on Tuesday night.
The fire broke out around 10:30 p.m. at or near a malfunctioning pump, said Breck Slover, battalion chief with the El Segundo Fire Department. There was no explosion, but loud bangs from electrical transformers blowing up were heard at the plant. The cause of the pump malfunction is unknown, Slover said.
