Army Corps Expects Permit Decision on Line 5 Tunnel This Fall

The U.S. Army Corps of Engineers has announced an expedited timeline for its review of Enbridge's proposed Line 5 tunnel project beneath the Straits of Mackinac, following a presidential declaration of a national energy emergency. The draft Environmental Impact Statement (EIS) will be released on May 30, launching a shortened 30-day public comment period instead of the usual 60 days. This tunnel aims to house a replacement segment of the Line 5 pipeline, which transports oil and natural gas liquids between the Midwest and Ontario. Supporters argue the tunnel will enhance safety, while environmental groups and Indigenous tribes warn it could threaten the Great Lakes and undermine adequate public participation. The Army Corps' permit decision could come as early as this fall, months ahead of previous expectations, though final project approval also requires state permits. The public can submit feedback on the project through a dedicated website during the comment period.
