(Clairton, PA) U.S. Steel is now facing new fines levied by the Occupational Safety and Health Administration (OSHA) as a result of findings that shed new light on why a valve ruptured at its Clairton Coke Works plant on August 11th, 2025 that led to an explosion at the location outside of Pittsburgh that left two people dead. The fines total nearly $120,000 for U.S. Steel and they are also levied against the contractor of MPW Industrial Services, whose employees were working to clean the valve that eventually broke on the day of the explosion last year. That contractor faces nearly $62,000 in fines. According to a statement from the U.S. Department of Labor released yesterday, the contractor failed to provide a relief valve for a high-pressure water system.
