DULUTH, Minn. (AP) - U.S. Steel Corp. says it has reached a tentative agreement with the United Steelworkers of America on a three-year labor contract.

The tentative deal announced Sunday would cover 16,000 employees nationwide. That includes 1,620 workers at U.S. Steel's mines in Minnesota's Iron Range.

The union still has to ratify the agreement. Terms of the agreement weren't immediately available.

John P. Surma is the CEO of the Pittsburgh-based company. He says he's pleased with the tentative agreement, and says it's in the best interest of the company, workers and shareholders.

A message left with a United Steelworkers spokesman was not immediately returned.

Contract agreements still haven't been reached between the Steelworkers and two other companies - ArcelorMittal and Cliffs Natural Resources.
