U.S. District Judge Brian Morris’ came down Thursday. Calgary-based TransCanada was preparing to build the first stages of the oil pipeline in northern Montana. Environmental groups had sued TransCanada and The U.S. Department of State in federal court in Great Falls.
Morris says the government’s analysis didn’t fully study the cumulative effects of greenhouse gas emissions. The analysis also didn’t fully study the effects of current oil prices on the pipeline’s viability or include updated modeling of potential oil spills.
The 1,184-mile pipeline would transport up to 830,000 barrels of crude a day from Alberta, Canada and Montana to facilities in Nebraska.
