The Keystone Pipeline system consists of the operational Phase I, Phase II, and Phase III, the Gulf Coast Pipeline Project. A fourth, proposed pipeline expansion segment Phase IV, Keystone XL, failed to receive necessary permits from the United States federal government in 2015. Construction of Phase III, from Cushing, Oklahoma, to Nederland, Texas, in the Gulf Coast area, began in August 2012 as an independent economic utility. Phase III was opened on January 22, 2014, completing the pipeline path from Hardisty, Alberta to Nederland, Texas. The Keystone XL Pipeline Project (Phase IV) revised proposal in 2012 consists of a new pipeline from Hardisty, Alberta, through Montana and South Dakota to Steele City, Nebraska, to "transport of up to of crude oil from the Western Canadian Sedimentary Basin in Alberta, Canada, and from the Williston Basin (Bakken) region in Montana and North Dakota, primarily to refineries in the Gulf Coast area". The Keystone XL pipeline segments were intended to allow American crude oil to enter the XL pipelines at Baker, Montana, on their way to the storage and distribution facilities at Cushing, Oklahoma. Cushing is a major crude oil marketing/refining and pipeline hub.
