The amount of natural gas in a black rock formation under Pennsylvania is so vast that it could supply all of America’s energy needs for 10 to 15 years, said John Hanger, Secretary of the Pennsylvania Department of Environmental Protection, in an interview with Bay Daily.
The development of a drilling technique called hydraulic fracturing to unlock the gas in the Marcellus Shale formation is a “game changer” for the United States, he said. The discovery could provide cheaper energy and help in the fight against global warming, Hanger said.
But drilling is also environmentally invasive. In northeastern Pennsylvania, drilling has caused chemical spills, contamination of drinking water with methane, an explosion, and fish kill. These incidents in the Dimock area were reported in Monday’s Bay Daily. The problems illustrate the need for Pennsylvania to become increasingly vigilant over the drilling boom, Hanger said.
“We are increasing oversight over this industry, because it is imperative that as this industry grows, oversight must accompany it,” the state environmental secretary said in a recent telephone interview conducted for public radio and the Chesapeake Bay Foundation.
