Update On Michigan Tar Sand Spill

A report blames the company and federal regulators:

Preventable safety blunders by the pipeline operator Enbridge and lax federal regulation led to the disastrous 2010 rupture and oil spill in the Kalamazoo River, the National Transportation Safety Board said Tuesday.

Corrosion and cracks overlapped in many areas of the pipeline, but the company failed to consider the problem in safety evaluations, it said. The pipeline spewed 843,000 gallons of oil sands crude into the river, soiling 35 miles of wetlands and waterways and sickening 320 people and nearly 4,000 animals.

The company has a history of spills in Wisconsin and a plan to add capacity to its state operations.
