Pollution control systems at US Steel’s Clairton Coke Works had been shut down following an electrical fire at the facility. The fire caused closure of the same two control rooms damaged in a December 24 fire. As a result of the fire, Control Rooms 2 and 5, which house equipment and controls used to operate pollution controls, including desulfurization, were shut down. Control Room 1 was operating normally. There were no injuries. Late at night US Steel said “Repairs were completed and normal operations have been resumed at Clairton Coke Works. They have successfully restored the desulfurization process. Restarting the desulfurization facility and minimizing the potential for impacts to the environment and community were of the highest priority for the company. During the suspension of desulfurization capabilities no exceedances of sulfur dioxide were recorded at nearby air quality monitors.”

Desulfurization is a process used to clean coke oven gas, a byproduct of the coke-making process, in order to remove sulfur.

PennEnvironment and the Clean Air Council filed a lawsuit in federal court in April over alleged Clean Air Act violations related to coke oven gas pollution since the December fire. Allegheny County Health Department joined the suit in May. The lawsuit is seeking a court order that would require US Steel to comply with air permits, an order that would require US Steel to remediate harm caused to local communities as well as hefty civil penalties to punish US Steel for past violations and deter future violations.
