In several recent studies on methane emissions relating to the natural gas industry, scientists concluded that the U.S. Environmental Protection Agency (EPA) underestimated the quantity of methane the industry releases to the atmosphere. A study released Monday, based on air samples above wells in the Marcellus Shale formation in Pennsylvania, indicates that methane emissions may be from 100 to 1000 times higher than EPA estimates. But this study also found that hydraulic fracturing was not a primary source of methane emissions.
Also this week, EPA released five white papers for peer review identifying fracking, along with compressors, leaks, liquids unloading and pneumatic devices, as a potentially significant source of methane and volatile organic compound (VOC) emissions. The papers are the first step in President Obama’s Climate Action Plan Strategy to Reduce Methane Emissions targeting several areas, including the oil and gas sector, for reducing methane emissions.
