Enbridge has filed environmental permitting applications for the Great Lakes Tunnel project with Michigan Dept. of Environment Great Lakes and Energy (EGLE) and the US Army Corps of Engineers (USACE).
The permit filing will keep the project on schedule and moving forward. While the tunnel is constructed, the safe and continued operation of the existing Line 5 pipeline, is essential to Michigan's oil and gas industry and the small, local businesses who depend on consistent access to the pipeline to ship their product.
The design of the tunnel hasn’t been finalized, but the permit application outlines an 18-foot to 21-foot diameter tunnel running 60 to 250 feet below the lake bed. Work will begin on about 25 acres in the Lower Peninsula and move north to an about 16-acre Enbridge-owned parcel in the Upper Peninsula.
Livonia-based Jay Dee Contractors Inc. and Obayashi Corp. will construct the tunnel, while Arup will handle engineering and design.
Given the importance of Line 5 to Michigan’s communities, our economy, and the survival of our businesses, its encouraging to see that the tunnel project is on schedule and that Enbridge anticipates construction to be underway as early as the end of 2021.
Additionally, Enbridge has created more fact sheets on the tunnel project:
