PORTLAND, Ore. -

Canadian authorities have approved sending natural gas to an Oregon terminal where it would be liquefied for export overseas.

The Oregonian reports the National Energy Board of Canada has approved a 25-year natural gas export license for Oregon LNG, whose terminal would be near the mouth of the Columbia River, in Warrenton.

The Canadian board determined that the quantity of gas to be sent to Oregon is surplus to Canadian requirements, and the gas resource base in Canada can accommodate foreseeable Canadian demand.

Oregon LNG faces a number of domestic permitting hurdles, including approval from U.S. regulators to export gas to countries that don't have a free trade agreement with the United States. That includes some of the largest potential customers in Asia, including Japan, China and India.
