PA DEP Report: Counties with Fracking Have More Air Pollution

Last week the Pennsylvania Dept. of Environmental Protection (DEP) reported they filed a required every-three-year air pollution study with the federal Environmental Protection Agency (EPA). The results? Because of fracking and a change away from burning coal to burning natural gas for electrical power generation, all major forms of air pollution, including carbon monoxide, nitrogen oxide and volatile organic compounds, have gone down—significantly (see “Thank You for Fracking” – Air Pollution Goes Down in PA).

MDN now has a copy of the official numbers filed by the DEP to the EPA (see the files embedded below showing the data). It appears to us there is a “rest of the story” in the DEP’s numbers. While air pollution numbers are extremely positive and have gone down significantly as a statewide average, in counties with a lot of Marcellus Shale drilling, air pollution numbers have gone up. Compared to the levels found in other counties, we’d call it a “significant” increase. Is there cause for concern?
