Today Dr. John Stansbury, a Professor of Environmental and Water Resources Engineering at the University of Nebraska, released a study of the worst case spill scenarios for TransCanada's proposed Keystone XL tar sands pipeline. His study, the first independent analysis of the worst-case spill scenarios for the Keystone XL pipeline, cites significant flaws in TransCanada's methodology for calculating both the frequency and severity of expected spills on Keystone XL. The study finds that Keystone XL will have more than eight times as many spills, take more than ten times as long to shut down in the event of a rupture and spill more than six times as much raw tar sands as TransCanada estimates.
