The proposed reroute is expected to cross nearly 200 bodies of water and temporarily affect 55 hectares of wetlands. Enbridge says the nearly 70-year-old pipeline is a vital link to fuel across the region. Wisconsin Public Radio reports that the Great Lakes Indian Fish and Wildlife Commission, which represents 11 Ojibwe tribes, told the DNR in a Dec. 10 letter that the state’s review has significant gaps in information.

They also say it doesn’t assess compliance with the Bad River tribe’s water quality standards or combined impacts of other projects.
