Schuette, Wyant request information on Mackinac Straits Enbridge oil pipelines

 Attorney General Bill Schuette and Department of Environmental Quality Director Dan Wyant today announced they are seeking detailed information on the current status of two Enbridge oil pipelines laid in the Mackinac Straits more than sixty years ago.   The formal request to Enbridge Inc. and Enbridge Pipelines Inc., asks for detailed information to ensure the Great Lakes are protected from a catastrophic spill in the event of a pipeline failure.  


“We have a responsibility to practice good stewardship of the Great Lakes, the crown jewels of Michigan’s ecology and economy,” said Schuette.  “The unique location of these pipelines, in the straits, means failure is not an option.  This request is part of a comprehensive approach to ensure we work aggressively to minimize risks and protect the lakes at every turn.”

“This Administration has worked hard to protect the environment and support the industries we regulate," said DEQ Director Dan Wyant. "We are asking for assurance that Enbridge is monitoring and maintaining its infrastructure. Michigan does not need another pipeline break. Our vast, vital natural resources must be protected.”

The letter signed by Schuette and Wyant asks for detailed information within 60 days, including:

•Pipeline Life Expectancy:  Details on the construction, modification, and estimated life expectancy of the pipelines, as well as any anticipated replacement plans.

•Pipeline Use: Existing and potential uses for the pipelines in the future.

•Preventive Maintenance and Leak Prevention: Pipeline inspection processes and mechanisms for leak prevention, detection and control.

•Spill Response Plans:  Company response plans in the event of a leak or spill.
