Check Out The Major Sources Of Industrial Air Pollution In Allegheny County


Whether you’re new to the Pittsburgh region or have lived here your whole life, you probably want to know what’s in the air you’re breathing and where it’s coming from.

This map from PublicSource identifies the facilities that federal standards say are the “major sources” of industrial air pollution in Allegheny County and the amount of pollutants they are allowed to release.

The air permits, issued by the Allegheny County Health Department, were collected by the Group Against Smog and Pollution (GASP), which allowed PublicSource to map and publish the information.

The permits are publicly available information, but are not easily accessible information, said Jamin Bogi, policy and outreach coordinator with GASP.
