BIG SPRING, TX (KWES) -

If you were wondering what was going on at the Big Spring Oil Refinery on Wednesday morning, it was just a drill.

Delek U.S., the company who owns the refinery, tells us they were running through an emergency response drill for an underground hydrocarbon storage facility.

You probably know it as a "salt well."

The refinery tells us they were just following railroad commission rules.
