Revised Draft SGEIS on the Oil, Gas and Solution Mining Regulatory Program (September 2011)

Well Permit Issuance for Horizontal Drilling and High-Volume Hydraulic Fracturing in the Marcellus Shale and Other Low-Permeability Gas Reservoirs

DEC received more than 13,000 public comments on the Draft Supplemental Generic Environmental Impact Statement (SGEIS) issued in September 2009. The Draft SGEIS addresses permit conditions required for gas drilling in Marcellus Shale and other areas of the State.

In response to issues raised, DEC has prepared a Revised Draft SGEIS. As of September 7, 2011, the document was available for public review. To help those interested in understanding the issues involving horizontal drilling and high-volume hydraulic fracturing, several fact sheets were also available.

The comment period on the proposed regulations regarding high-volume hydraulic fracturing (HVHF) ended on January 11, 2013.
