The Michigan Department of Environmental Quality (MDEQ) today  issued a permit to Enbridge Pipelines Line 5 (Lakehead) LLC to install four additional helical anchoring support structures on existing parallel pipelines designated as Line 5 on the bottomland of Lake Michigan beneath the Straits of Mackinac.

The four supports are proposed to maintain the integrity and safety of the existing pipeline and to comply with Enbridge’s Straits of Mackinac Pipeline Easement.  The easement requires the exposed portions of the pipeline be anchored and/or supported with a minimum distance of 75 feet between supports. The company also needs a United States Army Corps of Engineers permit to this project.

Enbridge had requested approval to install up to an additional 18 supports.

Due to significant public comment, and after consultation with The Grand Traverse Band of Ottawa and Chippewa Indians, the MDEQ has decided to defer a permitting decision on the additional 18 supports.

The MDEQ will continue to work with the company, Michigan Tribal Governments, and other stakeholders to address comments received regarding the additional 18 supports.

The DEQ is dedicated to respect for Michigan's citizens, stewardship of the environment, and support for a sustainable economy.
