About U.S. Natural Gas Pipelines - Transporting Natural Gas           
 based on data through 2007/2008 with selected updates


Currently, there are 58 locations at which natural gas can be exported or imported into the United States, including 9 LNG (liquefied natural gas) facilities in the continental United States and Alaska (There is a tenth U.S. LNG import facility located in Puerto Rico). At 28 of these locations natural gas or LNG currently can only be imported; while at 17 they may only be exported (1 LNG export facility is located in Alaska). At 13 of the 58 locations natural gas may, and sometimes does, flow in both directions, although at each of these sites the flow is primarily either import or export.
