And why is oil via the Capline Pipeline acceptable and not the Keystone?
Canadian Oil Sands Production Finds a New Outlet to the U.S. Gulf Coast The Capline pipeline, connecting Patoka, Illinois to St. James, Louisiana, is now fully operational, transporting heavy crude oil produced in Canada’s tar sands to refiners along the U.S. Gulf of Mexico.
The 632-mile, 40-inch pipeline system historically moved crude from the Louisiana Gulf Coast to Midwestern refiners, but was recently reversed to allow the delivery of oil from Canadian tar or oil sands to Gulf Coast refineries and shipping terminals.
