and North Slope producers more time to explore the best market for Alaska gas. By the summer of 2014 the project became more focused on export, so the state and TransCanada terminated their AGIA agreement. History Initial evaluations Large natural gas reserves were discovered in Prudhoe Bay in 1967. Talk of a pipeline peaked during the 1973 OPEC oil embargo and several companies came out in favor of large pipeline projects. Canadian Arctic Gas Pipeline, Ltd.—a consortium of large oil companies including Shell, Exxon, and TransCanada—proposed a route from Alaska's Prudhoe Bay across northern Yukon to the Mackenzie Delta, and then south through the Mackenzie Valley to Alberta. In addition, the Foothills Pipeline consortium pursued a competing Mackenzie Valley Pipeline, starting at the Mackenzie Delta and also running along the river valley to Alberta. Either proposal required the approval of the Canadian government, which named Thomas Berger to lead an inquiry into the proposals. Berger's inquiry resulted in a recommendation for a ten-year moratorium on development of the pipeline to deal with issues such as Aboriginal land claims and setting aside of conservation areas. In the United States, three competing applications were filed with the Federal Power Commission to construct a natural gas pipeline from Prudhoe Bay. A proposal sponsored by El Paso Corporation routed the pipeline to Valdez along the oil pipeline route with LNG tankers then transporting the gas to terminals on the west coast. The other two proposals would cross Canada on a route parallel to the Alaska Highway. The Federal Power Commission conducted lengthy hearings on the relative merits of the three plans, and under the Natural Gas Act the Commission had the legal right to select the final route. Following the 1976 elections where John McMillian, CEO of Northwest Pipeline was a major supporter of Jimmy Carter, President Carter proposed special legislation to transfer the task of selecting a project from the Federal Power Commission to the President. Congress adopted the Alaska Natural Gas Transportation Act of 1977, and Carter selected the project sponsored by Northwest to the exclusion of the other two projects. The Commission then proceeded to conduct further proceedings to issue certificates of public convenience and necessity to authorize construction of pipelines from Prudhoe Bay and extending to San Francisco and Chicago, and the United States and Canada entered into an agreement regarding having the gas pipeline follow the Alaskan Highway route.
