"Sioux tribe's concerns were echoed in official reports by the EPA and two other agencies, but Army Corps of Engineers brushed them aside."
"BISMARCK, N.D.—Senior officials at the U.S. Environmental Protection Agency and two other federal agencies raised serious environmental and safety objections to the North Dakota section of the controversial Dakota Access oil pipeline, the same objections being voiced in a large protest by the Standing Rock Sioux tribe that has so far succeeded in halting construction.
But those concerns were dismissed by the U.S. Army Corps of Engineers, which relied on an environmental assessment prepared by the pipeline's developer, Dakota Access LLC, when it approved the project in July, according to public documents.
The 1,134-mile pipeline would carry approximately 500,000 barrels of crude per day from North Dakota to Illinois along a route that did not originally pass near the Standing Rock reservation, the documents show. After the company rerouted the pipeline to cross the Missouri River just a half-mile upstream of the reservation, the tribe complained that the Army Corps did not consider threats to its water supply and cultural heritage."
