Line 5 Wisconsin Segment Relocation Project

Line 5 is a vital link to propane and other energy supplies for the upper Midwest, and has been safely operating across northern Wisconsin since 1953. Every day, this 645-mile-long, 30-inch diameter pipeline plays a critical role transporting 540,000 barrels of light crude oil, light synthetic crude oil, and natural gas liquids to a regional network for this area.


In July 2019, the Bad River Band of Lake Superior Chippewa Indians filed a lawsuit seeking the removal of Line 5 from the Bad River Reservation. Enbridge is proposing a relocation of a 12-mile section of Line 5 from the Bad River Reservation, replacing it with approximately 41 miles of pipe outside of the Reservation.

Line 5 in Wisconsin: Consider the alternative
The Line 5 underground pipeline was built in 1953 to remove oil-carrying tanker traffic from the Great Lakes, and avoid oil transportation by truck and rail. We’ve been safely operating Line 5 for more than 65 years.

Consider the alternative. If we were to transport the same amount of product by tanker truck, an estimated 2,100 trucks would need to travel east every day on US-2 from Superior to transport products currently carried by Line 5.

Our commitment to the environment
Safety of people, and protection of the environment, is our top priority. Whether we’re planning, building, maintaining or operating a pipeline, we take special care to minimize our impact on the surrounding environment.

From wildlife protection strategies, to Horizontal Directional Drilling, to using pre-existing corridors of activity, to habitat restoration, we work hard to minimize our long-term impact to land along our pipeline routes.

Sustainability at Enbridge
Sustainability is central to everything we do. Across our business, we’ve committed to net-zero GHG emissions from our operations by 20501, 3—and reducing emissions intensity from our operations 35% by 2030.1, 2

We have an important role to play in providing access to cleaner energy. That role involves contributing to GHG emission reductions goals and seeking new and improved ways to deliver energy safely, responsibly and sustainably.

Pipeline construction: Safety and the environment
Project information
‘No good alternatives to a pipeline’

That’s what Superior, WI business leader Todd says about Line 5. Moving product by truck or rail “is just going to mean higher prices and higher costs . . . a pipeline is the safest, most economical way to transport these energy fuels.”

'You couldn’t live out here without heat'

Chris, who delivers propane to communities, says propane “makes it possible” to live and work in northern Wisconsin. Chris supports the Line 5 Wisconsin Segment Relocation Project: “It’s been proven the safest way to move petroleum product, by far, is a pipe.”

‘I always come back’ to Wisconsin’s natural beauty

Joe, an engineer with Enbridge, was born in Mellen and still has a family cabin in the area “to reconnect with the woods.” Joe takes pride in ensuring safety, and notes the L5WSRP has earned 100% landowner approval.

‘I call Enbridge my neighbors’

Kelly and her husband Doug own and operate a hobby farm on the Minnesota-Wisconsin border, with Enbridge pipelines crossing their property. “I have found all the land agents to be really easy to work with,” says Kelly.

Superior Terminal tank safety drill

“We’re practicing for the scenarios that we hope will never happen.” Chief Scott Gordon of the Superior, WI, Fire Department says he knows of no other mutual aid groups with emergency response preparedness like the Superior Petroleum Partnership.

Strong roots in the Wisconsin community

Hayward, Wisconsin has hosted the Lumberjack World Championships every year since 1960, with Enbridge its title sponsor for more than a decade. D.J., Chief of Competition for the annual showcase event, recalls that Enbridge stepped in to save the event during the economic downturn of 2009. “We were in some really rocky waters,” he says. “That relationship (with Enbridge) made this event that much better.”

Committed to Ashland and Iron Counties

Joe Barabe is Mayor of Mellen, Wisconsin, “a little city that works.” Joe talks about Enbridge’s $1.5-million purchase of five acres of city land for our Line 5 Segment Relocation Project, and how those funds will benefit multiple projects in Mellen. “It’s been win, win, win across the board,” he says.

A life-saving tool when minutes count

A grant from the Enbridge Safe Community First Responder program has paid for an Automated External Defibrillator (AED) to be placed in each of the Iron County Sheriff’s Department’s 11 squad cars in Hurley, WI. “The AEDs now arrive with the deputies on patrol, and can be used anytime we respond to a medical emergency,” says Sheriff Paul Samardich.

Connecting Wisconsin communities with nature

Copper Falls State Park is a 600-acre jewel in northern Wisconsin. A pair of Enbridge grants will help connect local communities to this majestic park by establishing a new walking and cycling trail: “We can all work together to create a project that we can all be proud of—that all of us can use.”

Regulatory information
Project permit applications: Wisconsin Department of Natural Resources (DNR)

Several permitting agencies review the project. Construction will not begin until permits are received, and Enbridge encourages public participation in the process.

The construction process

1 GHG emissions included within our targets are from assets over which we have operational control (Scope 1 and Scope 2 emissions). Projected reductions of GHG emissions intensity and absolute emissions is relative to the 2018 baseline year. For more information, see our 2023 Sustainability Report.
2 This metric aggregates emissions and throughput for each business unit on the basis of tonnes of carbon dioxide equivalent per energy delivered in petajoules (“PJ”).
