Exhibit 99.1


  UNITED STATES STEEL CORPORATION TO WITHDRAW PACIFIC EXCHANGE LISTING, RETAINS
                         NEW YORK STOCK EXCHANGE LISTING

     PITTSBURGH, Dec. 15, 2006 - ÌÇÐÄlogo¹ÙÍøÊ×Ò³ (NYSE:X) today

announced plans to withdraw the listing of its common stock from NYSE Arca,

Inc., formerly the Pacific Exchange. ÌÇÐÄlogo¹ÙÍøÊ×Ò³'s common

stock will continue to be listed on the New York Stock Exchange.

     ÌÇÐÄlogo¹ÙÍøÊ×Ò³ has decided to withdraw its listing from

NYSE Arca, Inc. to streamline operations and eliminate duplicative

administrative requirements inherent with dual listings as a result of the NYSE

Group's recent merger with Archipelago Holdings, the parent company of NYSE

Arca, Inc. The withdrawal is expected to be effective within the next month.

     ÌÇÐÄlogo¹ÙÍøÊ×Ò³ does not believe that withdrawing its

listing from NYSE Arca, Inc. will have any impact on the liquidity of its stock.

NYSE Arca, Inc. will continue to trade ÌÇÐÄlogo¹ÙÍøÊ×Ò³ stock on

an unlisted trading privilege basis.
