On May 13, 2011, Pennsylvania Governor Tom Corbett signed Senate Bill 265 into legislation. SB 265 sets a minimum distance between natural gas "well clusters" (defined as the area within a well pad holding horizontal wells and comprising an area of no more than 5,000 square feet) overlying workable coal seams, and provides for coordination of gas well drilling and coal mining. Under the new legislation, the Department of Environmental Protection (DEP) will issue no new permits for any well unless that well's cluster is at least 2,000 feet from the nearest well cluster or the operator of the well and owner of any workable coal seams underlying the proposed well provide written consent to spacing of less than 2,000 feet. In addition, no permits will be issued for wells located less than 1,000 feet from any other wells (excluding injection wells not penetrating workable coal seams, plugged wells, nonproducing wells drilled prior to November 30, 1955, or storage wells). The bill also requires well operators intending to drill in any operating coal mine to attach the written consent of the mine operator to permit applications.
