The program, which would take place over a period of years, involves the construction of two new technologically and environmentally advanced coke batteries and a cogeneration facility, along with environmentally focused rehabilitation of several existing coke batteries.
The new coke batteries would replace the current capacity of several older units and incorporate state-of-the-art emissions control technology that would meet all regulatory requirements of the U.S. Environmental Protection Agency and the Allegheny County Health Department, according to the company. U. S. Steel also plans to rehabilitate Clairton’s remaining coke batteries.
Coke oven gas from coke battery operations would be consumed in the proposed cogeneration facility, which would supply electricity for all three Pittsburgh-area Mon Valley Works facilities: the Clairton plant; the Edgar Thomson plant, a steelmaking operation in Braddock, Pa.; and the Irvin plant, a rolling and finishing facility in West Mifflin, Pa.
U. S. Steel expects to file for environmental permits with the Allegheny County Health Department in early January 2008.
