Kudos to President Barack Obama for rejecting the Keystone XL pipeline project ("Au revoir, Keystone," Nov. 8). As a civil engineer, I have worked on a number of pipeline projects, and I have yet to see any persuasive evidence that construction and operation of the Keystone pipeline will yield any economic or environmental benefits to the United States.
The pipeline is intended to convey oil extracted and liquefied from tar sands in Canada and conveyed through the U.S. for export to foreign markets. None of the product is intended for our domestic market. Oil pipelines are notoriously prone to leakages that can cause significant environmental damage. So we have here a project where the benefits of cheaper oil are shipped overseas and the risk of environmental damage is retained in the U.S. Not exactly a good deal for us.
