Enbridge’s contentious plan to reroute an aging pipeline around a northern Wisconsin tribal reservation moved closer to reality Thursday after the company won its first permits from state regulators.

Wisconsin Department of Natural Resources officials announced they have issued construction permits for the Line 5 reroute around the Bad River Band of Lake Superior Chippewa’s reservation. The energy company still needs discharge permits from the DNR and the U.S. Army Corps of Engineers.

The project has generated fierce opposition. The tribe wants the pipeline off its land, but tribal members and environmentalists maintain rerouting construction will damage the region’s watershed and perpetuate the use of fossil fuels.

The DNR issued the construction permits with more than 200 conditions attached. The company must complete the project by Nov. 14, 2027, hire DNR-approved environmental monitors and allow DNR employees to access the site during reasonable hours.

The company also must notify the agency within 24 hours of any permit violations or hazardous material spills affecting wetlands or waterways; can’t discharge any drilling mud into wetlands, waterways or sensitive areas; keep spill response equipment at workspace entry and exit points; and monitor for the introduction and spread in invasive plant species.

Enbridge issued a statement praising the approval, calling it a “major step” toward construction that will keep reliable energy flowing to Wisconsin and the Great Lakes region.

Bad River tribal officials warned in their own statement Thursday that the project calls for blasting, drilling and digging trenches that would devastate area wetlands and streams and endanger the tribe’s wild rice beds. The tribe noted that investigations identified water-quality violations and three aquifer breaches related to the Line 3 pipeline’s construction in northern Minnesota.
