Exhibit 99.1




           U. S. STEEL DISAPPOINTED BY INDIANA COURT OF APPEALS RULING

     PITTSBURGH, March 10, 2008 - United States Steel Corporation (NYSE: X)
announced today that the Indiana Court of Appeals reversed a previous decision
of the Indiana Utilities Regulatory Commission (IURC) involving a rate
escalation provision in U. S. Steel's electric power supply contract with
Northern Indiana Public Service Company (NIPSCO).  The decision, handed down by
the Court on Friday, March 7, 2008, held that a rate provision in a 1999
agreement between the parties applied to certain electric demand charges since
October 1, 2005 - that will continue until July 2009 - and remanded the case to
the IURC for calculation of the charges.  U. S. Steel is surprised and
disappointed over the outcome of the case, which it had won on a summary
judgment motion before the IURC.  U. S. Steel intends to seek a review of this
decision by the Indiana Supreme Court, but expects to establish a pre-tax
reserve of approximately $45 million in its first quarter results related to
prior year effects.
