Feds warned company in Mich. spill about pipeline

A worker monitors the water in Talmadge Creek in Marshall Township, Mich., near the Kalamazoo River as oil from a ruptured pipeline, owned by Enbridge Inc, is vacuumed out the water Thursday, July 29, 2010. A Canadian company whose pipeline leaked hundreds of thousands of gallons of oil into a major Michigan river was warned by government regulators in January that its monitoring of corrosion in the pipeline was insufficient.
