UPPER MICHIGAN (WLUC) – The U.S. Army Corps of Engineers has released the final version of its Environmental Impact Statement for Enbridge’s proposed Line 5 Tunnel Project.

For months, the USACE has been examining the scope, construction and need for Enbridge’s Line 5 project. It would see the current Line 5 replaced with a new tunnel that runs four miles along the Mackinac Straits, and would bury it underground with a one-foot-thick concrete liner.

The USACE just released its final statement on the environmental impact, which assesses the possible risks to the Great Lakes and the surrounding environment. It also assesses possible alternatives to the proposed project. The review will be used to determine if the permit can be issued.

Several groups and tribes have opposed the project, even filing legal challenges with the Michigan Supreme Court. Flow Water Advocates is one of those groups.

In response to the release of this final EIS, Flow officials say in part:

“The proposed Line 5 Tunnel Project would result in both short- and long-term detrimental impacts, including permanent wetland and wildlife habitat losses; potential release of drilling fluids to ground and surface waters; up to six years of construction noise, lights, traffic, and vibrations; limits to recreational activities; destruction of archeological resources; and housing values and tourism.”

But Enbridge’s communications strategist says the EIS has been thorough and science-driven. In a statement, Enbridge said:

“This final EIS incorporates extensive study and meaningful input from stakeholders across Michigan and the Great Lakes region. An EIS is the highest standard of federal environmental review, and the Corps’ detailed work underscores their careful and methodical approach to minimizing environmental and community impacts, an objective we strongly support and share.”

A final permitting decision from the Army Corps of Engineers is expected within 30 days. Enbridge is also awaiting renewal of its permit with the Michigan Department of Environment, Great Lakes and Energy.
