Oct 4 (Reuters) - Chevron ( CVX ) 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 ( CVX ) 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 ( CVX ) spokesperson said.
