Keystone XL Tar Sands Pipeline Could Have 91 Serious Spills in 50 Years

via internet science tech

We've already heard some figures on how bad the ongoing Yellowstone River oil spill would likely be if it was of the capacity of the proposed Keystone XL tar sands pipeline (roughly 20 times worse). Now environmental engineer John Stansbury has set out some scenarios which further detail how bad an oil spill would be with a higher capacity pipeline and just how often serious spills are likely to occur (hint, much more than operator TransCanada would like you to believe).

Stansbury notes that TransCanada, in its estimates, sees the possibility of 11 serious spills on the pipeline during the course of 50 years. He argues existing data suggests a more realistic estimate would be 91 accidents during that half century.

He also took issue with TransCanada's claims that it could shut down a pipeline within 19 minutes of a leak. A slow leak in a remote area of Montana or Nebraska could go undetected for days or even weeks between inspections, he warned. (The Guardian)
