The Most Expensive Onshore Oil Spill in U.S. History

The largest onshore oil spill in US history -- Enbridge's ruptured Line 6B that released nearly 3 million liters of tar sands diluted bitumen into a tributary of the Kalamazoo River in Michigan -- finally has an official price tag: $1,039,000,000 USD. That's according to newly disclosed figures released by Enbridge in a Revised Application to expand another one of its pipelines, the Alberta Clipper.
