MDEQ Approves Permit to Add Four Helical Supports to Enbridge Line 5

The Michigan Department of Environmental Quality issued a permit Monday, October 3, to Enbridge Pipelines Line 5 (Lakehead) 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 complete this project.

Enbridge had requested approval to install up to an additional 18 supports. Because of significant public comment, and after consultation with the Grand Traverse Band of Ottawa and Chippewa Indians, the DEQ will defer a permitting decision on the additional 18 supports.

The DEQ will continue to work with the company, Michigan tribal governments, and others to address comments received regarding the proposed additional 18 supports.
