One person was killed in an overnight fire at a processing unit of Chevron Corp’s 330,000-barrel-per-day refinery in Pascagoula, Mississippi, a Jackson County emergency official said. The fire was contained and extinguished by plant personnel, said Earl Etheridge, director of Jackson County Emergency Services. The refinery is Chevron’s largest and most complex. "There were unconfirmed reports of an explosion," Etheridge said. "There has been one confirmed death." The fire came after a Chevron pipeline exploded on Thursday near a tiny Texas town south of Dallas, prompting evacuations from nearby homes and a school district.
