U. S. Steel Announces Management Changes at Its Mon Valley Works Facilities


PITTSBURGH, Feb. 27 /PRNewswire-FirstCall/ -- United States Steel Corporation (NYSE: X) today announced two management changes at its Mon Valley Works operating facilities. Lisa A. Roudabush has been appointed general manager of Mon Valley Works and Mark G. Tabler has been named plant manager- Clairton Plant. Roudabush replaces Anton Lukac, who was named vice president- engineering & technology earlier today. Roudabush will report to Anthony R. Bridge, vice president-operations, East. Tabler replaces Roudabush at Clairton and will report directly to her. The changes are effective March 1.

Roudabush, 47, will be responsible for overseeing operations at four facilities: the Edgar Thomson Plant (primary operations) in Braddock, Pa.; the Irvin Plant (finishing) in West Mifflin, Pa.; the Clairton Plant (coking and coal chemical operation) in Clairton, Pa.; and the Fairless Plant (galvanizing) near Philadelphia.

Roudabush began working at U. S. Steel in 1982 as a student co-op at the Research and Technology Center in Monroeville, Pa. Upon graduating from college later that year, she joined the company as a management associate at the research center and progressed through a series of increasingly responsible research engineer positions before she was named research manager for coated products in 1992.

In 1994, Roudabush was transferred to the quality assurance department at Gary Works in Gary, Ind., to serve as manager of technology planning. She moved through several different quality assurance positions in various areas of the plant before she was named quality assurance manager-sheet products in 1997. Two years later, she advanced to manager of technology for the department.

Roudabush was named manager-process technology at Mon Valley Works in 2001. She returned to the company's Research and Technology Center in 2003 to serve as general manager of research and advanced to general manager-processed products in 2004. She assumed her most recent position, plant manager- Clairton Plant, in December 2006.

Roudabush, a Pittsburgh native, graduated from Carnegie Mellon University in 1982 with a bachelor's degree in metallurgical engineering. She also completed graduate-level work in metallurgical engineering and engineering management at the University of Pittsburgh.

In his new position, Tabler, 46, and a native of Lima, Ohio, will manage coking and coal chemical operations at the largest by-product coke plant in the Western Hemisphere. Coke serves as the primary fuel for the company's blast furnaces. Tabler joined U. S. Steel in November 2006 as director-coke battery assessment at the company's Pittsburgh headquarters. Prior to arriving at U. S. Steel, he spent 19 years at AK Steel, where he advanced through increasingly responsible management positions including general manager of the company's Butler (Pa.) Works and its Ashland (Ky.) Works.

Tabler earned a bachelor's degree in metallurgical engineering from The Ohio State University in 1984. He is married and has four children.
