The Energy Department has given conditional authorization for exports of liquefied natural gas from a proposed terminal in Coos Bay, on the Oregon coast.
The approval Monday means Jordan Cove LNG Terminal is the seventh project to get such authorization, although the start of exports may be years away.
The terminal would ship gas to countries that do not have a free trade agreement with the United States.
The facility would be able to export up to 0.8 billion cubic feet per day of natural gas, for a period of 20 years.
Jordan Cove must still go through an environmental review and final regulatory approval.
The push for natural gas exports comes amid a boom largely resulting from a drilling technique known as hydraulic fracturing, or fracking.
