MUCC Submits Public Comment in Support of Line 5 Tunnel Project


Lansing, MI — Michigan United Conservation Clubs (MUCC), the nation’s largest statewide conservation organization, has submitted formal public comments urging the U.S. Army Corps of Engineers to approve the Enbridge Line 5 Tunnel Project. In a letter submitted today, MUCC emphasized the need to move this critical infrastructure forward to protect the Great Lakes while maintaining safe, reliable energy transportation.


“MUCC supports the tunnel project as the best available alternative to reduce the risk of an environmental disaster in the Straits of Mackinac while continuing to deliver essential energy products to Michigan families and industries,” said Amy Trotter, CEO of MUCC. “We believe the tunnel project strikes a balance between protecting the environment and maintaining energy security.”


MUCC’s position is backed by a formal resolution passed by its membership, which includes thousands of hunters, anglers, trappers, and outdoor enthusiasts across Michigan. The resolution supports the tunnel as a long-term solution that replaces the aging and exposed pipeline segment currently crossing the Straits, offering greater environmental safeguards through secondary containment.


The organization cited the Draft Environmental Impact Statement (EIS), which acknowledges the tunnel’s benefits, including reduced spill risk and a controlled, buried environment for transporting light crude oil and natural gas liquids. MUCC also rejected the "no action alternative," which would allow the existing line to remain in operation without any new protective infrastructure.


“Other alternatives, like transporting fuel by truck or rail, are inefficient and carry greater environmental and safety risks,” Trotter added. “Allowing the current line to operate exposed on the lakebed indefinitely is simply not acceptable.”


MUCC’s comment stresses that the organization is not weighing in on the type of energy transported, but rather on the environmental risks and safety benefits of the tunnel itself.


Originally approved by the Michigan legislature and governor in 2018, the Great Lakes Tunnel Project represents a once-in-a-generation investment in infrastructure and environmental protection. MUCC urges the U.S. Army Corps of Engineers to issue the necessary permits and move forward with construction without further delay.

On the Ground: Brush Piles and Invasive Species at Denmark Township Mini State Game Area

By Olivia Triltsch • May 21, 2026
On Friday, May 15, 2026, high school students who are part of the Reese High Outdoors Club joined MUCC’s On the Ground Junior program and the Michigan Department of Natural Resources (DNR) at the Denmark Township Mini State Game Area. Students completed a wildlife habitat improvement project by clearing a grassland habitat of invasive woody growth maintained for pheasants. Using the cut vegetation from the area, students constructed several large brush piles throughout the site to benefit small mammals and other wildlife in the area. Maintaining open grassland habitat is important for supporting species that rely on early successional cover for cover or feeding. Due to suppression of natural disturbances, active management helps to control woody vegetation from gradually overtaking the areas and reducing habitat quality for species that rely on the grassland. The project area is near fields planted by the DNR to provide both habitat and food sources for wildlife, making these improvements part of a larger habitat management effort on the property. In total, students directly improved 10 acres of wildlife habitat through this project. Beyond the on-the-ground impact, the event also allowed students to try a hands-on conservation experience and the ability to contribute to habitat management and public land stewardship in Michigan. Projects like this continue to demonstrate the value of engaging the next generation in Michigan's outdoor heritage and wildlife conservation efforts.

On the Ground: Jack Pine Planting Day 2026

By Olivia Triltsch • May 7, 2026
On Saturday, May 2, 2026, a group of dedicated volunteers joined Kirtland's Warbler Alliance, Huron Pines, Saginaw Children’s Zoo, and MUCC's OTG program in planting approximately 4,800 jack pine saplings within the Grayling Forest Management Unit in Crawford County. Jack pines are a critical nesting habitat feature for the once-threatened Kirtland’s warbler. In total, volunteers directly impacted about 7 acres of land were prepared by the Michigan DNR for this planting to allow volunteers to maximize their efforts across the land. This is one of our annual events that is perfect for helpers of all ages and interests.
