05:43 AM EDT, 04/17/2026 (MT Newswires) -- Valero Energy ( VLO ) has partially restarted operations at its Port Arthur, Texas oil refinery after an explosion and fire on March 23 lead to a shutdown, Reuters reported Thursday, citing two people familiar with the matter.

While the production line from the AVU 147 crude distillation unit is operating, Valero is still repairing the heater in the AVU-146 crude distillation unit and keeping that production line shut until the work is complete, according to the report.

Valero did not immediately respond to MT Newswires' request for comment on the matter.
