One of the dingbat poobahs, speaking on national television, stated that the Keystone Pipeline was absolutely necessary to reduce our dependence on "foreign oil." Looks like this particular politician is a spokesman for the "awl bidness" as they say in Texas. But I have to wonder what rock he lives under.?
This pipeline is designed to carry sour crude, extracted from Alberta tar sand, to refineries in the Houston area. Last time I checked the atlas, Alberta is in Canada and Canada is not in the United States. Ipso facto, this will be "foreign oil."
This pipeline is designed to cross the Ogallala Aquifer, the major source for water in the central US. A bad leak in that area would prove disastrous.
Those target refineries are clustered in the Houston area. That makes it very convenient for a major hurricane, or terrorist action to take them all out. For what this pipeline is going to cost, it seems to me that it would be cheaper to build a new refinery in Wyoming.
As for the claim that no tax payer money will be involved, if you believe that, I have some Las Vegas real estate and some Nigerian treasury bonds I will sell you at a real good price.
