In a report submitted to the Securities and Exchange Commission on Monday, Enbridge increased its estimate of how much it will cost to clean up the company’s Kalamazoo River oil spill. The Kalamazoo Gazette reports that the company has revised its cleanup estimate from $585 million to $700 million. Enbridge spokeswoman Terri Larson told the Gazette that costs have increased due to a need for additional testing, continual reassessments, shoreline cleanup and more operations to recover submerged oil.
