Enbridge/State of Michigan Agreement


This week, Enbridge and the State of Michigan signed an agreement setting forward a plan to improve coordination between the company and the State for the operation and maintenance of Enbridge’s Line 5 pipeline, while providing enhanced transparency to the citizens of Michigan.

Here are seven ways this agreement protects Michigan’s waters:

  • By June 2018, we will have evaluated three options for the eventual replacement of the dual pipelines in the Straits of Mackinac. The options that we will evaluate with the State include: placing a new pipeline in a tunnel under the Straits; installing a new pipeline below the lakebed of the Straits using horizontal directional drilling (HDD); and, creating a trench on the bottom of the Great Lakes and placing a new pipeline in a secondary containment structure or system.
  • Temporarily shut down the operation of Line 5 when adverse weather conditions create sustained waves higher than eight feet in the Straits
  • Put into place additional safety measures to further protect against a potential anchor strike from boats in the Straits
  •  By June 2018, evaluate additional state-of-the-art tools and underwater technologies that could help further inspect and maintain Line 5 in the Straits and assess the condition of the coating on the twin pipelines
  • Work with the State on plans to enhance safety and reduce the potential impacts at other Line 5 water crossings
  • Replace the Line 5 St. Clair River crossing as soon as we receive the necessary federal (U.S. and Canada) and state approvals. The new pipe will be installed underneath the river bed using HDD; and,
  •  Increase coordination with the State regarding the operations, maintenance and future of Line 5 and promote transparency between Enbridge and the State of Michigan. State representatives will have access to our data, studies, and will collaborate with us every step of the way.
