It involved a whopping $1.5 billion upgrade to the three Mon Valley Works plants, all in Pennsylvania â the Edgar Thomson Plant in Braddock, the Irvin Plant in West Mifflin and the Clairton Coke Works in Clairton â with technology and improvements that would have resulted in cleaner air for all three communities as well as good-paying jobs providing regional prosperity for decades.
On April 30, U.S. Steel said that after months of tug of war with the Allegheny County Health Department, it was canceling the $1.5 billion upgrade and idling three batteries at Clairton Coke Works by 2023.
