Recent Department Comments to EPA or other Proposals:

Marcellus Shale Long-Term Air Monitoring Project Report

The Department of Environmental Protection undertook a project to examine the impacts from air emissions from unconventional gas production within Washington County. Data was collected over a one-year period in 2012-2013 and results were subjected to a series of analyses conducted by DEP, DOH and the federal Agency for Toxic Substances and Disease Registry (ATSDR). Air quality measurements were collected from 5 Washington County sites, and an additional comparison was performed using data from an air monitoring station in Adams County. Air quality was monitored for ground-level ozone, particulate matter, carbon monoxide, nitrogen oxides, hydrogen sulfide and methane. Additionally, the air was tested for over 60 toxic volatile organic compounds (VOCs). Continuous meteorological data was also collected.

The air data was compared to National Ambient Air Quality Standards (NAAQS), ATSDR public health comparison values, Air Quality Index (AQI) indicators, and background values found in Pennsylvania. The data was also subjected to a screening-level risk quantification for hazardous air pollutants. The report from ATSDR can be found here.

Analysis of Data: Long-Term Particulate Matter Monitoring (Bath Borough, PA)

The department initiated continuous, 24-hour ambient air monitoring for total suspended particulate (TSP), sulfate and select metals at a location near the Keystone Cement Company production facility in East Allen Township, Northampton County, PA in 1995. Sampling was initiated to monitor the facility's particulate emissions in the ambient air and to evaluate the potential health effects on the community. Upon completion of the sampling in 2015, the data was analyzed and compared to health-based screening values. The findings from the analysis can be found in the following report.
