The company stated that no jobs will be affected by the closure. U.S. Steel has permanently shut down one of the most prolific batteries at its Clairton Coke Works, part of a settlement reached with environmental groups and the Allegheny County Health Department earlier this year. Battery No. 15 contained around 10% of the facility's coke ovens, according to Zach Barber, a clean air advocate with PennEnvironment. It had been idle since 2020. No jobs will be impacted, according to U.S. Steel. PennEnvironment, along with the Clean Air Council and county health department, reached a settlement with U.S. Steel in January concerning a 2018 fire at the plant that damaged pollution controls. Environmental groups and government officials lauded the deal as a win for the region. "One of the single biggest parts of that settlement was the closure of Battery 15," Barber said. "Seeing that it's happening now, we're hopeful it'll pay health dividends for residents for years to come."
