The Pennsylvania Land Trust Association has reviewed environmental violations accrued by Marcellus Shale drillers working in Pennsylvania between January 2008 and June 25, 2010. The records were obtained via a Right to Know Request made to the PA Department of Environmental Protection (DEP).
The Pennsylvania Land Trust Association seeks to protect Pennsylvania’s special places and landscapes for today and for generations to come.
To increase the quality and pace of land conservation, PALTA helps conservation practitioners improve their effectiveness, builds public understanding, and advocates for better governmental policy.

In April, 2010, the Academy’s Center for Environmental Policy presented a public panel discussion, “The Marcellus Shale – The Science and the Policy.” Video of this program is available on our website.
On September 28, 2010, Dr. David Velinsky, vice president of the Academy’s Patrick Center for Environmental Research, testified before the City Council of Philadelphia about the scientific questions at hand and need for new research. A copy of his testimony is available for download.
We propose to look at four streams in each of three size classes for each of the three levels of well density (none, low and high). We will also use computer modeling to analyze the impact of drilling on deforestation. When this study has been completed, we will be able to indicate with a much higher level of certainty what the ecological risks are of drilling in the shale and how they might be managed. It is this and other types of scientific studies that are needed to provide regulators and drillers the necessary information for environmentally sound gas extraction from Pennsylvania.
In conclusion, I would like to thank the Council for this opportunity to discuss these

issues. We believe the gas in the Marcellus Shale could have positive effects on the
Pennsylvania economy, and there may be possible ways it could be extracted safely.
Again, I’d like to emphasize that the Academy does not take a position on the overall
advantages or disadvantages of obtaining gas from the Marcellus Shale. At this time,
however, there remain significant uncertainties and we urge a cumulative impact
assessment on the scale described above before any large‐scale drilling occurs.
