Pipeline Break Causes Oil to Pollute Michigan River VOA News 27 July 2010 An oil pipeline break has occurred in the northern U.S. state of Michigan, causing an estimated 19,500 barrels of crude to leak into a creek that flows into the Kalamazoo River. The company operating the pipeline, Enbridge Energy Partners, says the break occurred Monday, forcing the shutdown of the pipeline pumps. The Houston-based company says the cause of the leak is under investigation. No injuries have been reported. Enbridge says crews have been dispatched to the site and are deploying oil skimmers and absorbent booms on the creek and river to minimize environmental impacts. Michigan Senator Carl Levin said Tuesday that his office has been in close contact with the relevant federal agencies to make sure those carrying out the cleanup have all the resources they need to complete the job as soon as possible. The pipeline carries oil from the midwestern state of Indiana into Ontario, Canada. Some information for this report was provided by AP and Reuters. .
