As part of SkyTruth’s ongoing analysis of gas and oil drilling in Pennsylvania (see HotSpot Map blog and Abandoned Wells blog) we’ve begun exploring the effects of the Marcellus play on national and state forests.
This issue has been of concern to environmentalists and residents alike for several years. In 2009 the U.S. Forest Service was sued by conservation groups for allowing gas drilling to continue without the completion of environmental site assessments of potential drilling effects. The case was ruled in favor of such assessments, but drilling companies and private mineral owners with stakes in the Allegheny were quick to appeal. In September, 2011 the settlement requiring environmental site assessments before drilling can begin was overturned, thus opening up the national forest for new gas and oil drilling, including horizontal drilling with hydraulic fracturing (fracking).
The map below illustrates drilling in Allegheny National Forest from January 2005 – October 2011:
