In a court-ordered review, the U.S. Army Corps of Engineers concluded that the Dakota Access Pipeline poses "no significant potential impact" to nearby hunting and fishing resources, and its crossing of the Missouri River does not create a "disproportionately high and adverse" risk to nearby Native American tribes, some of whom oppose the $3.8 billion, 1,200-mile crude oil pipeline. A federal judge ordered the review in June 2017, but allowed the pipeline to continue operations. Sponsor Energy Transfer Partners LP reported this June that the pipe, which has transported more than 100 million bbl, is moving 500,000 b/d, or close to half of the Bakken Shale's daily production.

Enbridge Energy Partners LP and the Fond du Lac Band of Lake Superior Chippewa have reached an agreement to replace the Line 3 crude oil pipeline, which traverses the band's reservation in northeast Minnesota. Financial terms were not disclosed. The agreement gives Enbridge easements for six existing oil pipelines through 2039. Line 3 was built in the 1960s and carries Canadian crude from Alberta through North Dakota and Minnesota to Enbridge's terminal in Superior, WI.
