MILWAUKEE, Wis. (WRN) — Great Lakes tribes are withdrawing their cooperation in the construction of a pipeline in northern Wisconsin.

The Milwaukee Journal Sentinel reports that construction plans for Enbridge Line 5 line are being fast tracked by the Trump Administration.

The line had to be re-routed around the Bad River Tribe reservation in northern Wisconsin after the Canadian company lost its easement through the tribe’s land. Enbridge also plans to run the line under the Straits of Mackinac separating Lakes Huron and Michigan. Last week, six Great Lakes tribes withdrew from the project review process.

The tribes in Canada and Michigan said the Army Corps of Engineers had informed them that the permit will likely be issued soon, and that the Corps was no longer acting in good faith. The tribes stated they no longer wished to lend credibility to a project that will endanger the lakes if a leak occurs.
