IT'S JUST A TOTEM:

 In a far corner of North Dakota, just a few hundred miles from the proposed path of the Keystone XL pipeline, 84,000 barrels of crude oil per day recently began flowing through a new line that connects the state's sprawling oilfields to an oil hub in Wyoming.

In West Texas, engineers activated a new pipeline that cuts diagonally across the state to deliver crude from the oil-rich Permian Basin to refineries near Houston. And in a string of towns in Kansas, Iowa and South Dakota, local government officials are scrutinizing the path of pipeline extensions that would pass nearby.

While the Keystone project awaits a final decision, scenes like these are unfolding almost every week in lesser-known developments that have quietly added more than 11,600 miles of pipeline to the nation's domestic oil network.

Overall, the network has increased by almost a quarter in the last decade. And the work dwarfs Keystone.
