Valero Refinery Explosion: What Caused the Port Arthur, Texas Explosion?

Emergency services rushed to the Valero refinery in Port Arthur, Texas, after nearby residents reported a loud explosion that rocked their homes.

A shelter-in-place order was also reportedly issued for the west side of Port Arthur as thick black smoke from the fire filled the sky.
