      Attorney General wants details on status of 61-year-old oil pipeline

      State officials want detailed information about life expectancy, use, maitenance and emergency plans.

      Attorney General Bill Schuette and Department of Environmental Quality Director Dan Wyant are seeking detailed information on the status of two Enbridge oil pipelines laid in the Mackinac Straits more than sixty years ago.

      The letter asks for detailed information to ensure the Great Lakes are protected from a catastrophic spill if a pipeline failed.

      "The unique location of these pipelines, in the straits, means failure is not an option," Schuette said. "This request is part of a comprehensive approach to ensure we work aggressively to minimize risks and protect the lakes at every turn."

      DEQ Director Dan Wyant said the administration has worked hard to protect the environment and support industry.

      "We are asking for assurance that Enbridge is monitoring and maintaining its infratstructure."

      Enbridge Inc. has sixty days to give the administration information about the pipelines' life expectancy, what they are used for, how they are inspected, and emergency plans in case of a spill.

      The pipes were laid in 1953. Earlier this year, Enbridge Energy Partners LP told the Associated Press the pipes are in good shape and pose no threat.

      Concern has rised in the past year after serious spills in Arkansas and North Dakota.

      In 2010, another Enbridge pipeline ruptured, sending more than 840,000 gallons of crude into the Kalamazoo River.
