Valero’s Wilmington Refinery Still Impaired

Valero Energy Corp. said it would take three or four days before its Wilmington refinery was back at full production after an outage that cut power to most of Los Angeles, including the plant.

Although one coker unit was restored to service after Monday’s outage, another remains shut and may start again in three or four days, Valero said. One crude-oil processing unit also resumed operation. A fluid catalytic cracker is expected to resume operation as well.
