FACT:

Pittsburgh and Allegheny County have some of the worst air pollution in the United States — with more than 1.2 million people at risk.

OUR REGION’S AIR IS
STILL POLLUTED

In 2018, air quality in the Pittsburgh region was considered NOT GOOD for 229 days (2/3 of the time). [3]
From 2016-2018, three regional air monitors registered particulate matter (PM 2.5) concentrations worse than 90% of the U.S. [3]
From 2016-2018, seven out of 10 monitors in the Pittsburgh region had PM 2.5 levels worse than 80% of the U.S.
For 2016-2018, two of the Pittsburgh region’s 10 ozone monitors ranked in the worst 20% nationally. [3]

WHO ARE THE BIG POLLUTERS?

Allegheny County Health Department Title V Facilities

These are the biggest polluters in Allegheny County, all required to obtain a Title V permit under the Clean Air Act because they have the potential to emit more than 100 tons of a single pollutant.

The Toxic Ten

Allegheny County polluters are fouling our air and threatening our health. PennEnvironment’s latest report finds that ten industrial facilities in Allegheny County emitted more than 955,000 pounds of toxic pollutants in 2016 – contributing more than 70 percent of the air pollution from all industrial sources in the county.

Our Region's Hazardous Air Pollutants

Our region’s public health crisis is due in large part to pollution from industrial power plants and diesel source like trucks, school buses and heavy machinery. Read the PRETA report.

FRACKING AND THE PETROCHEMICAL RISK

Plans for a petrochemical “hub” in the Ohio River Valley, including the Shell plant in Beaver County currently under construction, present a public health crisis for our region. A petrochemical plant means more fracking, more pipelines, and more gas infrastructure.

Air pollution is the single largest risk of the petrochemical build out. Volatile organic compounds (VOCs) can cause eye, nose and throat irritation, frequent headaches, nausea, and can also damage the liver, kidneys and central nervous system.
