Supplemental Draft EIS Comments

The proper precautions do not seem to have been taken to ensure the Great Lakes are not massively polluted due to this project. It is imperative to protect the Great Lakes not only as they are staples in the culture of the Midwest for everyone to enjoy. But they provide a key source of fresh water for the country as a whole which in increasingly important as droughts continue to plague the west side of the country year after year.

Furthermore the effect the Great Lakes have on preserving and allowing numerous aquatic species to thrive cannot be understated. Too many species to name migrate through these lakes each year to breed and feed allowing them to continue to flourish. This will not continue if we fill them up with pollution.
Finally, there has not been enough of an explanation provided as how this would even benefit the residents of Michigan or the US. It appears the proceeds from this dangerous and irresponsible project would go directly back to a private company based in Canada. The Great Lakes would be assuming all of the risk and receiving none of the reward. At the very least there needs to be more transparency with who this project benefits the most. But all in all you should just leave the damn lakes alone.

Enbridge has not provided sufficient information–on the full project, its potential environmental impacts, or the available alternatives–for EGLE to properly consider its application for a Water Resources Permit under Part 325 and Part 303 of Michigan’s Natural Resources and Environmental Protection Act . When all of the necessary information is considered, it is clear that the tunnel project cannot be lawfully permitted because the project will have more than minimal environmental effects, and because the shutdown of Line 5 is a viable, and much preferable, alternative to constructing an unprecedented tunnel project to house a new section of oil pipeline through the heart of the Great Lakes. Enbridge does not have the necessary legal authorization to operate the proposed tunnel project in the Straits, as required under the Great Lakes Submerged Lands Act and Michigan’s public trust doctrine.

This project is a bait and switch by Enbridge and the Army Corps of Engineers after focusing on the tunnel for years.

Enbridge cannot safely perform HDD drilling in the straits of Mackinaw. Their track record in their line 3 expansion project demonstrates this.

This project still forces Michigan taxpayers to carry all of the risk for a foreign corporation.

The tunnel authority, such as it is, lacks sufficient insurance, a clear violation of the 1953 Easement, and the 1977 Transit Pipeline treaty. Therefore, until and unless they can provide proof of having over $4 Billion in insurance, the tunnel should not be permitted.

Hello. I am writing today to publicly state my staunch opposition to the proposed Line 5 project. There are far too many potential risks, including the likelihood of irreversible devastation to our water, soil and air. Enbridge has repeatedly demonstrated complete disregard for laws, people and land, and there is no reason to believe that they won’t continue to operate in such a manner in their endless pursuit of financial gains. Enbridge also has a clear track record of being unable to safely perform HDD drilling, as demonstrated in the numerous frac-outs in their Line 3 expansion project. Frankly, it is absolutely outrageous that this is even being considered as a viable option.
Alternative: Rather than continuing to double down on energy systems that are known to be finite and running out- ie fossil fuels- we need to shift and invest resources into renewable energy sources.
Again, I am expressing my utmost opposition to the Line 5 project, and strongly urge those in power to reject this proposal, and to instead turn towards alternatives that will be life-affirming for generations to come.
Thank You.

Please see signed attached submission from Canada.

Regarding Line 5 tunnel proposal issued on November 13, 2025 by the US Army Corps of Engineers as a supplement to the May 2025 draft environmental impact statement (EIS), as I resident of the area impacted by this study, I strongly object to this reckless adventure in destroying the stated land and negatively impacting every living thing. Additionally, this proposal would be setting up conditions for an environmental disaster without any possibility to contain or remedy any leaks to the environment so vital to our community. Enbridge has demonstrated inability to safeguard its lines leading to environmental disasters right here in Michigan.

This pipeline should simply be closed!

This is to covey my support of the Enbridge pipeline under the straits of Mackinaw. I believe the benefits outweigh the risks involved.

I oppose any of the plans to continue transporting fossil fuels through a pipeline that crosses the Straits of Mackinac. In considering the environmental impact of any alternative plan to replace the current pipeline, the future greenhouse gas emissions, the necessity of transporting fossil fuels through the Straits, and the potential for significant stranded assets should all be factored in. I believe that there is no adequate justification for undertaking an enormously costly construction project which will continue our reliance on fossil fuels for decades to come and yet still risk polluting the largest body of fresh water in the United States.

I am very much opposed to using land on the south side of the Straits to build the Enbridge pipeline above ground. This would require clearcutting a large amount of public land used by the public and wildlife, and block two roads. It would take a lifetime for the cleared area to grow back to the shape it’s in now. The two blocked roads would require a very lengthy detour for many residents to get to their homes, and could prove life threatening if they needed an emergency vehicle. And noise would be detrimental to those in the vicinity and could prove a health risk.
Land effected include the Headlands which has a Dark Sky Park, and numerous walking and cross-country ski trails. It would cross May Woods which also has a good trail system, and go down the east side of French Farm Lake which has trails and is popular for hunting. As your analysis indicates in addition to the usual type of wildlife, this is a habitat for two types of much needed bats.
In addition, if the pipeline was built this way and there was a leak, how would Enbridge contain it?
