It was unclear whether there were injuries or whether a fire was burning at the refinery owned by Dallas-based Alon USA, which employs about 170 people and produces about 70,000 barrels a day.

"All I know is that it blew up," said the dispatcher, who declined to give her name.

John Moseley, managing editor of the Big Spring Herald, heard the blast and said, "I thought it would knock the walls down."

Blake Lewis, a spokesman for Alon USA, said the company had an unconfirmed report of an incident but did not know any details. He said a plant manager was on the way to the plant.

Big Spring is about 280 miles west of Dallas.
