The cross-border Keystone XL pipeline was hit with another setback on Aug. 15 when a U.S. District Court judge in Montana ordered the U.S. State Dept. to perform a supplemental environmental impact statement on a new route through Nebraska. Developer TransCanada had planned to begin construction in mid-2019. The new route was approved by state regulators in 2017 as an alternative to TransCanada’s preferred route through the state’s environmentally sensitive Sandhill region. The new route was not covered by the line’s 2014 environmental impact statement. Keystone XL would move oil from the Canadian oil sands to Nebraska. The company did not respond to a question about how the ruling could impact its construction schedule. Work is expected to take two years.
