WASHINGTON, Aug 7 (Reuters) - The Obama administration on Wednesday approved natural gas exports from a third U.S. facility, the second permit issued in about three months, triggering debate over whether the review of a long backlog of export applications is picking up steam.
The export terminal in Lake Charles, Louisiana, was given a conditional license from the Department of Energy to ship liquefied natural gas to all countries. The terminal is backed by BG Group Plc and Energy Transfer Partners LP's Southern Union Co.
The department's order gives the Lake Charles terminal permission to export up to 2 billion cubic feet of natural gas a day for 20 years. The approval is contingent upon the Lake Charles terminal receiving a permit from the Federal Energy Regulatory Commission for construction of the facility.
