NBC10 (Philadelphia) is reporting on a study that finds that oil and gas operations in Pennsylvania are contributing to reduced air pollution in the state: "A new state report says Pennsylvania's natural gas industry remained a relatively small contributor of air pollution in 2012 from industrial facilities, despite including more compressor stations than 2011. *** The Department of Environmental Protection released the data Thursday. *** Overall, the amount of pollution from industrial facilities dropped in 2012, and the department said that was at least in part because of increased natural gas use."
