Clairton Coke Works
U.S. Steel Corporation is cancelling its $1 billion upgrades to its Mon Valley Works facilities, which includes Edgar Thomson Works in Braddock, Irvin Plant in West Mifflin, and the Clairton Coke Works in Clairton. While the cancellation will likely result in some job losses in the region, it will also reduce the levels of harmful air pollution in the Mon Valley and beyond.
The upgrades, which were announced May 2019, would have included a casting and rolling facility and a cogeneration plant. After several delays due to COVID in 2020 that increased the upgrade costs to a promised $1.5 billion, U.S. Steel pushed the start date of those upgrades to the fourth quarter of 2022. But today, the company announced it would be scrapping those plans entirely.
