The Sierra Club said Thursday it will try to block an energy company's plan to export liquefied natural gas to find new markets for the drilling boom that has flooded the Mid-Atlantic with natural gas. Virginia-based Dominion Resources Inc. is seeking to export 1 billion cubic feet per day through a terminal it owns in Maryland. A previous legal settlement dating to the 1970s gives the Sierra Club the ability to reject any significant changes to the purpose or footprint of the existing natural gas terminal in Cove Point, Md., 60 miles southeast of Washington.
