On March 9, the Group Against Smog And Pollution announced the Allegheny County Health Department fined U.S. Steel $13,200 for a failed stack test at the Clairton Coke Works on February 21.

According to ACHD, one of the company’s batteries emitted nearly four times as much particulate matter than permitted over a three-day period earlier this year.

The February 21 enforcement order, which was posted to the Allegheny County Health Department website March 6, indicates that U.S. Steel failed its emissions tests conducted on Oct. 8-11 and on Oct. 14, 2019 for fine particulate matter (PM2.5) at Clairton Coke Works C Battery.

According to the order, U.S. Steel was pumping out 12.3 pounds of PM 2.5 an hour on average during that period in October. Its installation permit limits the company from emitting more than 3.4 pounds per hour of the air pollutant.

On one of those days—Oct. 14, 2019—the Liberty-Clairton area residents endured some of the worst air quality in the nation, with AQI spiking to 163 that day.

U.S. Steel was also fined $743,000 for emissions violations at its Clairton Coke Works in January.
