Final federal approval for what is being called the "new Keystone" came from the Army Corps of Engineers on July 26--allowing the pipeline to move forward. The 1,168-mile long Dakota Access Pipeline (DAPL), also called the Bakken Pipeline, is comparable in length to the Keystone XL. It will cross four states and carry 450,000 barrels of oil a day from North Dakota to a transfer terminal in Illinois where it will connect with other pipelines and be taken to refineries.
