This livestream looks at the controversy over re-permitting Enbridge’s Line 5 oil pipeline, which passes through the Upper Peninsula and crosses the Straits of Mackinac along the lakebed. Jeff Towner, U.S. Army Corps of Engineers retired wildlife biologist and UPEC Board member, and Mike Ripley of the Chippewa Ottawa Resource Authority are the guests. Towner explains the regulatory path Enbridge has to go through for the Line 5 tunnel approval. Ripley discusses tribal efforts to shut down Line 5 because of the dangers a spill would pose to their fisheries, which they operate under rights recognized by the Treaty of 1836.
