The New York State Department of Environmental Conservation (DEC) has been engaged in a comprehensive review of the potential environmental impacts of development of the Marcellus Shale in New York since 2008. The DEC is the regulatory agency in New York responsible for issuing drilling permits and regulating oil and gas exploration and production. The DEC had previously studied the environmental impacts of hydraulic fracturing in 1992, at which time it issued a Generic Environmental Impact Statement recommending certain safeguards in that practice. In 2009, the DEC issued for public comment a "Draft Supplemental Generic Impact Statement" analyzing the impact of hydraulic fracturing of horizontal Marcellus wells. As a result of comments received, the DEC has issued a revision of that draft report, which will be finalized later this year and again issued for public comment. During this study, New York has imposed a moratorium on issuance of any permits for horizontal wells in the Marcellus Shale.
The Marcellus extends over a huge area from West
Virginia through Pennsylvania and covers a substantial part of New York
State. Potential Marcellus reserves in New York are huge, and
exploration companies have leased huge areas in New York for
exploration. New York landowners have watched impatiently as wells have
been drilled in Pennsylvania, while environmental activists in New York
have opposed any drilling in that state.
The most recent version of the New York DEC's study
and recommendations is several hundred pages and provides a thorough
study of the potential impacts of drilling Marcellus wells on the
environment, including impacts on groundwater, surface water, air
quality and wildlife. The report proposes many revisions to DEC's
existing regulations concerning the construction of well pads, the
drilling and casing of horizontal wells, the handling and disposal of
frac fluids and chemicals, the disposal of returned frac water and drill
cuttings, the use of best available technology to reduce emissions from
equipment during drilling and completion operations, and the protection
of groundwater and surface water. The report discusses the current
state of technologies for use of fluids other than fresh water for
hydraulic fracturing and for the recycling of frac water. The authors
also discuss recent incidents in Pennsylvania of groundwater and surface
water contamination from drillsites and their cause. There is a
comprehensive summary of the geology of shale formations and water
resources in New York.
