Keystone XL Would Put Jobs At Risk With Expensive, Toxic Oil Spills | A new report from the Cornell University’s Global Labor Institute shows how the expected spills from the Keystone XL tar sands pipeline risks many more permanent jobs than the 20 pipeline-operating jobs it could create. A study conducted by Dr. John Stansbury at the University of nebraska estimated that 91 significant Keystone XL spills can be expected over 50 years. Keystone XL will cross approximately 90.5 miles of recreational and special interest areas in Montana, South Dakota, Nebraska, Oklahoma, and Texas. Agricultural land and rangeland comprise 79 percent of the land area affected by the proposed Keystone XL pipeline — 93 percent of Keystone’s Nebraska route is farmland. Spills from corrosive and toxic tar sands crude risks the jobs of the 571,000 workers in the agricultural sector in the six states along the Keystone XL corridor and the $67 billion in tourism spending.
