Line 5 Tunnel under the Straits of Mackinac

The Michigan State Department of Great Lakes, Environment and Energy has asked Enbridge to rewrite its permit application to rebuild an oil and gas pipeline underneath the Straits of Mackinac and include alternative options. The State made clear that it was going to apply environmental standards in evaluating the permit; that the agency intends to consider what the impact of that pipeline will be, including on climate change.

The US Army Corps of Engineers has set a public comment period that will last through June 4 on construction of the 4-mile tunnel. Please send a comment to the Army Corps of Engineers today. Deadline is June 4, 2020.

The full Public Notice is here. From the Comments section of this Notice:

Comments on the project should be e-mailed but may also be submitted in writing and postmarked or delivered by the expiration date of this public notice [June 4, 2020]. Comments of a positive or negative nature may be submitted. All responses must refer to file number LRE-2010-00463-56-A19. We will interpret a lack of response as meaning that there is no objection to the permit application.

You must include your name and mailing address – whether you comment by email or snail mail.
