Exhibit 99.1


        U. S. STEEL FURTHER CONSOLIDATES OPERATIONS
                  FOR GREATER EFFICIENCY

     PITTSBURGH, March 3, 2009 - United States Steel

Corporation (NYSE: X) announced today that further

consolidation is necessary to maximize efficiency while

meeting customer demands.  Operations to be temporarily

idled over the next several weeks are the finishing and

coking operations at Hamilton Works in Hamilton, Ontario,

and the steelmaking and finishing operations at Lake Erie

Works near Nanticoke, Ontario.  Coking operations at Lake

Erie Works will continue production.  Approximately 1,500

employees will be affected.  Earlier today, U. S. Steel

representatives met with federal and provincial officials as

well as representatives of the United Steelworkers at these

facilities to notify them of the temporary idling.

     U. S. Steel plans to continue to temporarily

concentrate production at Mon Valley Works near Pittsburgh,

Pa.; Gary Works in Gary, Ind.; and Fairfield Works near

Birmingham, Ala.

     "The difficult decision to continue to temporarily

consolidate our production, we believe, is a necessary

response to current market conditions," said U. S. Steel

Chairman and CEO John Surma.
