Indigenous communities gird to fight US Army pipeline plan that threatens sacred waters, treaty rights to fish
The U.S. Army Corps of Engineers approved a permit for Enbridge Energy's Line 5 pipeline update, allowing a new segment to be buried under the Straits of Mackinac. Tribal nations oppose the project, citing threats to sacred waters and treaty rights, while the Army Corps claims the project complies with regulations. Enbridge aims to replace a 4-mile segment of the pipeline that carries oil and natural gas liquids.
