A study analyzing area traffic and ambient air quality data from an air quality monitoring station near U. S. Steel’s Mon Valley Works found
that there was a 40% decrease in particulate matter (PM2.5) ambient air concentrations when comparing
readings from before and after the COVID-19 stay-at-home order in Spring 2020.
In the study, environmental consulting firm Trinity Consultants verified U. S. Steel’s finding that included an analysis of data collected from the Liberty Monitor, along with Pennsylvania Department of Transportation (PennDOT) traffic data taken from within a 40-mile radius of that site. Over the period reviewed, there was no change in production at the Clairton Plant, while the number of total vehicles on southwestern Pennsylvania roadways in the area examined fell by 50%.
