U. S. Steel Names James T. Volanski General Manager-Environmental Affairs

United States Steel Corporation (NYSE: X) announced today that James T. Volanski has been appointed general manager-environmental affairs, replacing J. David Moniot, who has elected to retire after 36 years of service to the company. Volanski will be responsible for overseeing U. S. Steel's environmental efforts in the United States as well as at its operations in Slovakia and Serbia. The appointment was effective January 1, 2007.

"Safeguarding the environment is one of our company's core values," said U. S. Steel Chairman and Chief Executive Officer John P. Surma. "Dave's expertise in environmental affairs was recognized throughout our industry and his efforts during his career helped our company become known as a leading proponent of environmental stewardship among steelmakers around the world.

"Jim's experience in a variety of environmental disciplines and his proven record of effective management will be key to our company's ongoing efforts to maintain our environmental leadership position," Surma noted.

Volanski, 49, graduated from the University of Pittsburgh in 1979 with a bachelor's degree in civil engineering. He joined U. S. Steel that year as a management trainee at Mon Valley Works near Pittsburgh, Pa., and in 1981, was promoted to environmental engineer. Between 1983 and 1993, he worked at several consulting, engineering and environmental service contractors that served the steel industry.

In 1993, Volanski returned to U. S. Steel, and over the next 10 years, he progressed through increasingly responsible positions and was involved in a wide range of environmental matters. In 2003, he was promoted to his most recent position, manager of the environmental department at Great Lakes Works, U. S. Steel's second largest domestic facility located near Detroit, Mich.

Volanski is a registered professional engineer and long-time member of the American Society of Civil Engineers and the Association for Iron and Steel Technology. He is also active in the American Iron and Steel Institute, serving as vice chairman of its Committee on Environment in 2006 before ascending to committee chairman in 2007.

He and his wife, Debra, and three of their children, Kaitlin, Andrew and Jacob, will relocate to the Pittsburgh area, where his eldest daughter, Jessica, attends Robert Morris University.
