MONITORING TOXIC POLLUTANTS

Toxic pollutants are a group of 187 pollutants identified by the federal Clean Air Act that have been associated with a wide variety of adverse health effects, including cancer. Toxic pollutants are emitted from various sources, including major stationary, area, as well as mobile sources. Although the focus on toxics in ambient air is relatively new, there are many local, state and national programs aimed at reducing toxic pollutants in the air we breathe.

MARCELLUS MONITORING

DEP Conducting Long-Term Marcellus Shale Air Monitoring Study in Southwestern Pennsylvania
The Department of Environmental Protectionhas begun a long-term, one-year air monitoring study of Marcellus shale development. The study, which is taking place in Washington County,measures ambient airborne pollutants in an effort to determine potential air quality impacts associated with the processing and transmission of unconventional natural gas.

The data from the study will allow DEP to assess any potential long-term impact of emissions from unconventional natural gas operations to nearby communities. This initiative will also assist the DEP in its efforts to address the cumulative impact of these operations in the Marcellus shale region.

For more information, call DEP's Bureau of Air Quality at 717-787-9702.

On Aug. 1, 2013, DEP released the Technical Support Document that outlines the methodology, study goals and technical information about the study.
