BIG SPRING - It was an open and shut case for part of the ALON USA Refinery in Big Spring on Monday.
Part of that refinery re-opened, only to shut down again.
That's after this fire erupted just after 8 Monday morning.
Investigators say the flames sparked up in an asphalt tank.
Right now, they're not sure how it started.
Officials say no one was hurt, and the fire was put out around 10.
Officials add the plant is in the process of restarting, but there is no timetable when it will be up in running again.
The refinery has been closed since the February 18th explosion.
