Pa. Studies on Shale-Site Air Emissions Incomplete: Court Documents

"Three widely cited state studies of air emissions at Marcellus Shale gas development sites in Pennsylvania omit measurements of key air toxics and calculate the health risks of just two of more than two dozen pollutants.

State regulators and the shale gas drilling industry over the past four years have repeatedly used the regional studies to support their positions that air emissions from drilling, fracking wastewater impoundments and compressor stations don’t pose a public health risk.

The revelations about the shortcomings of the state Department of Environmental Protection’s short-term air sampling reports are contained in sworn depositions by two DEP air program employees who worked on them."
