After being granted a postponement of oral arguments scheduled for November 14 in the U.S. Court of Appeals for the District of Columbia Circuit, the oil and gas industry and the Environmental Protection Agency are in settlement talks to resolve a lawsuit over a requirement that oil and gas companies obtain drinking water permits if they use diesel oil in hydraulic fracturing. The parties have until January 9 to file a motion to dismiss or provide a status report on negotiations. Paul Anastas, assistant EPA administrator for research and development, told the House Science, Space, and Technology Subcommittee on Energy and Environment November 17 that an agency study of the potential impacts of fracking on drinking water and groundwater is necessary to address public concerns, even though there is currently no evidence of contamination.
