The Keystone XL pipeline ________.

is a proposed 830,000-barrel-per-day crude oil pipeline running from Alberta, Canada to Steele City, Nebraska. The Keystone XL pipeline is a proposed expansion of the existing Keystone Pipeline System, which transports crude oil from Canada and the northern U.S. to refineries in Oklahoma and Texas Gulf Coast. The goal of Keystone XL is to increase the capacity of the existing pipeline and improve its flow from Alberta to Texas Gulf Coast refineries and on to foreign markets. The project has been the subject of heated debate and numerous legal proceedings, largely over environmental and safety concerns and the risk of oil spills along the route. Opponents of the Keystone XL project argue that the prolonged construction process risks irreparable environmental damage and that the potential economic benefits have been overstated.
