BIG SPRING - A bad welding job.
That's what officials at the ALON Refinery blame for an explosion at the plant earlier this year.
They tell us the blast was caused by a poor welding job on a pump case.
The refinery is checking similar pumps in the plant to make sure they are safe.
The unit involved in the blast is not being used right now, but officials say it doesn't play a big role in their production.
