Stop the Line 5 Oil Pipeline

Construction of a new Line 5 pipeline prolongs our dependence on harmful fossil fuels, threatens Treaty Rights, and puts some of Wisconsin’s most precious natural areas at risk.

Calgary-based Enbridge, Inc. is seeking permits from the Department of Natural Resources that would allow the company to reroute Line 5 across dozens of northern Wisconsin waterways and more than 100 acres of wetlands. The proposed route is upstream of Copper Falls State Park and poses a huge risk to the Bad River watershed.

Clean Wisconsin calls for immediate Line 5 shut down

Clean Wisconsin has filed a brief with the U.S. Court of Appeals for the Seventh Circuit calling for an immediate injunction against Line 5, saying a catastrophic rupture is imminent. Read More

In the last 50 years, Line 5 has leaked 29 times,

spilling more than a million gallons of crude oil into the environment.

Map of Line 5 Pipeline route and alternative routes

Originally built in 1953, Line 5 carries nearly 23 million gallons of crude oil and liquid natural gas every day from Superior, Wis. to refineries in Ontario, Canada. Much of that oil originates in the Canadian Alberta tar sands region.

Line 5 currently runs across the reservation of the Bad River Band of Lake Superior Chippewa, but easements that allowed the company to use tribal land expired in 2013. The tribe has since filed a federal lawsuit to expel Enbridge from its reservation.

Enbridge is now pushing to build a new 41-mile section of pipeline that would be routed around the reservation. But moving the line doesn’t eliminate the enormous risk it carries.

“What Line 5 means for me…”

Join Ojibwe attorney Philomena Kebec as she harvests wild rice in the Kakagon Sloughs, the largest undeveloped wetland system on the Great Lakes.

This sacred region, its waters, wildlife and traditions, is under threat because of the Line 5 pipeline.

Line 5 carries nearly 23 million gallons of crude oil and liquid natural gas across countless wetlands and waterways.

Clean Wisconsin joins a coalition of groups from across Wisconsin and the country opposing Line 5. Enbridge is required to obtain multiple state and federal permits to proceed with the reroute, and Clean Wisconsin will be closely monitoring the process and providing comments to relevant regulatory agencies. Help us tell DNR that Line 5 is bad for the climate and Wisconsin’s environment, and Enbridge shouldn’t be allowed to pollute our air and water for short-term profit.
