(Reuters) – Chevron  said on Saturday that it will be making operational adjustments to its 285,000 barrel-per-day El Segundo refinery to meet Southern California’s fuel demands after a large fire erupted on Thursday night at the refinery.

The El Segundo refinery is the second-largest in California and Chevron’s second-biggest refinery in the United States. The facility supplies a fifth of all motor vehicle fuels and 40% of the jet fuel consumed in Southern California.

An unplanned flare event occurred at the El Segundo refinery on Saturday following the extinguishing of the fire. “Future intermittent flaring is a possibility as these operational adjustments occur,” a Chevron spokesperson said.
