Public comment on Line 5 tunnel project permit open

The Line 5 tunnel project, a significant infrastructure initiative in Michigan, has sparked considerable debate and public interest due to its environmental, economic, and legal implications. This project centers on the replacement of a segment of the existing Line 5 pipeline, which currently runs beneath the Straits of Mackinac, a critical waterway connecting Lake Michigan and Lake Huron. Operated by Enbridge, a Canadian energy company, Line 5 transports crude oil and natural gas liquids across the Great Lakes region, serving as a vital energy conduit for Michigan, neighboring states, and parts of Canada. However, the aging pipeline, which has been in operation since 1953, has raised serious concerns about the potential for catastrophic oil spills in one of the most ecologically sensitive areas of the Great Lakes. The proposed tunnel project aims to address these concerns by encasing a new segment of the pipeline within a concrete tunnel beneath the lakebed, a solution that Enbridge argues will significantly reduce the risk of environmental disaster while maintaining the flow of energy resources.

The existing Line 5 pipeline consists of dual pipelines that span approximately 4.5 miles across the bottom of the Straits of Mackinac. Over the decades, the pipeline has faced scrutiny due to its age, exposure to strong underwater currents, and the potential for anchor strikes or other physical damage. Environmentalists and local communities have long voiced fears that a rupture could release millions of gallons of oil into the Great Lakes, which collectively hold about 20% of the world’s surface freshwater and serve as a drinking water source for millions of people. High-profile incidents, such as the 2010 Enbridge oil spill in Michigan’s Kalamazoo River—one of the largest inland oil spills in U.S. history—have only intensified public distrust of the company and heightened calls for the pipeline’s decommissioning. Opponents argue that the risks posed by Line 5 far outweigh its benefits, especially in light of the urgent need to transition away from fossil fuels to combat climate change.

In response to these concerns, Enbridge proposed the tunnel project as a compromise solution. The plan involves constructing a tunnel approximately 100 feet below the lakebed of the Straits of Mackinac, through which a new segment of the Line 5 pipeline would be housed. This tunnel, made of reinforced concrete, is designed to protect the pipeline from external threats such as anchor strikes or natural erosion, while also containing any potential leaks within the tunnel structure itself. Enbridge contends that this engineering feat represents a state-of-the-art approach to pipeline safety, effectively minimizing the risk of an environmental catastrophe in the Straits. The company has also emphasized the economic importance of Line 5, which supplies a significant portion of the propane used for heating in Michigan’s Upper Peninsula and supports refineries and petrochemical industries in the region. Shutting down the pipeline, Enbridge warns, could lead to energy shortages, higher fuel prices, and job losses.

However, the tunnel project has faced fierce opposition from a coalition of environmental groups, Indigenous communities, and concerned citizens who argue that it does not go far enough to address the broader issues associated with Line 5. Critics assert that building a tunnel merely perpetuates the region’s reliance on fossil fuels at a time when renewable energy alternatives should be prioritized. They also question the long-term safety of the tunnel, pointing out that even the most advanced infrastructure can degrade over time or be vulnerable to unforeseen events such as earthquakes or construction flaws. Indigenous tribes, particularly those with treaty rights to fish and hunt in the Great Lakes region, have been vocal in their opposition, citing the potential threat to their livelihoods and cultural heritage. The Bad River Band of Lake Superior Chippewa, for instance, has been engaged in a separate legal battle with Enbridge over a segment of Line 5 that crosses their reservation in Wisconsin, further complicating the pipeline’s future.

The legal and regulatory landscape surrounding the Line 5 tunnel project is complex and contentious. In Michigan, the project has required approvals from multiple state agencies, including the Department of Environment, Great Lakes, and Energy (EGLE) and the Public Service Commission (MPSC). These agencies have been tasked with evaluating the environmental impact of the tunnel, as well as its necessity and feasibility. Public hearings and comment periods have revealed a deeply divided populace, with some residents and business leaders supporting the project as a pragmatic solution to energy needs, while others decry it as a dangerous gamble with the Great Lakes. Michigan Governor Gretchen Whitmer has taken a firm stance against Line 5, ordering its shutdown in 2020 due to the risk it poses to the environment. Her administration has argued that the pipeline violates the public trust doctrine, a legal principle that obligates the state to protect natural resources like the Great Lakes for future generations. Enbridge, however, has resisted this order, leading to ongoing litigation between the company and the state.

Beyond state-level disputes, the Line 5 issue has international dimensions due to its role in cross-border energy trade between the United States and Canada. The pipeline originates in Superior, Wisconsin, crosses into Michigan, and continues into Ontario, making it a critical link in North America’s energy infrastructure. The Canadian government has invoked the 1977 Transit Pipeline Treaty, which governs the operation of pipelines crossing the U.S.-Canada border, to argue that Michigan lacks the authority to unilaterally shut down Line 5. This has escalated tensions, with Canada pushing for federal intervention to keep the pipeline operational while the tunnel project is under review. The Biden administration has so far avoided taking a definitive stance, leaving the matter to state and local authorities, though pressure from both Canadian officials and U.S. energy stakeholders continues to mount.

Public opinion on the Line 5 tunnel project remains sharply polarized. Supporters, including many in the energy sector and some local communities, view the tunnel as a necessary modernization that balances environmental safety with economic stability. They argue that the project will create jobs during construction and ensure a reliable energy supply for years to come. Opponents, however, see it as a shortsighted measure that fails to address the root causes of climate change and perpetuates environmental injustice, particularly for Indigenous communities whose voices have often been marginalized in the decision-making process. Activists have organized protests, petitions, and public campaigns to demand the complete decommissioning of Line 5, advocating for a just transition to renewable energy sources that would render such pipelines obsolete.

The environmental stakes of the Line 5 tunnel project cannot be overstated. The Great Lakes are a unique and irreplaceable ecosystem, home to diverse wildlife and a cornerstone of the region’s economy through tourism, fishing, and recreation. A major oil spill in the Straits of Mackinac could have devastating consequences, not only for the immediate area but for the entire Great Lakes system, as currents could carry contaminants across vast distances. Even with the proposed tunnel, critics argue that the risk of a leak—whether during construction or decades into the future—remains a looming threat. Enbridge, for its part, has committed to rigorous safety protocols and monitoring systems, but skepticism persists given the company’s track record of spills and regulatory violations.

As the debate over the Line 5 tunnel project continues, it serves as a microcosm of broader tensions surrounding energy policy, environmental protection, and climate change in the United States and beyond. The outcome of this project will likely set a precedent for how aging fossil fuel infrastructure is managed in an era of increasing environmental awareness and urgency. For now, the future of Line 5 remains uncertain, caught between competing visions of progress, safety, and sustainability. Whether the tunnel is ultimately built or the pipeline is decommissioned, the decision will have far-reaching implications for the Great Lakes region and the millions of people who depend on its resources. The ongoing public discourse, legal battles, and regulatory reviews underscore the complexity of balancing immediate energy needs with the long-term imperative to protect one of the world’s most vital natural treasures.
