“The 2019 Air Monitoring Network Plan, an annual report that describes how and where the county is monitoring air pollution, is available here . . . .
“The Liberty monitor, located at South Allegheny Middle/Senior High School in McKeesport, is not meeting U.S. Environmental Protection Act standards for sulfur dioxide or for particulate matter that is 2.5 microns or less — small enough to harm human lungs. The rest of the monitors meet EPA standards, said Ryan Scarpino, department spokesman.
“Among the changes, the plan proposes to reduce the frequency of particulate matter monitoring at the Avalon site from every three days to every six days.
“The plan also proposes adding photochemical assessment monitoring stations in Lawrenceville to measure hourly volatile organic compounds.
