UPDATE: 7:51 p.m. EST
A celebration is underway at Standing Rock after the U.S. Army Corps of Engineers denied an easement to allow the Dakota Access pipeline to cross Lake Oahe.
The Army Corps of Engineers announced Sunday that it has denied the current route for the Dakota Access pipeline, according to Standing Rock Sioux Chairman David Archambault II.
"Today, the U.S. Army Corps of Engineers announced that it will not be granting the easement to cross Lake Oahe for the proposed Dakota Access Pipeline," Archambault said in a statement. "Instead, the Corps will be undertaking an environmental impact statement to look at possible alternative routes."
The 1,172-mile pipeline is nearly complete except for a portion near the Missouri River reservoir in North Dakota where Native Americans and environmentalists have been camped out for weeks protesting to try and save the land.
"We wholeheartedly support the decision of the administration and commend with the utmost gratitude the courage it took on the part of President Obama, the Army Corps, the Department of Justice and the Department of the Interior to take steps to correct the course of history and to do the right thing," Archambault said.
News of this development first appeared on social media, according to CBS News. A man identified as Remi Baldeagle said the secretary of the Army had denied the pipeline easement.
“Up until this point the American government has failed us, but the American people haven’t, so I feel American today," Baldeagle said in the video.
The Dallas-based Energy Transfer Partners previously said it was unwilling to reroute the pipeline, which is a $3.8 billion venture to transport crude oil through the Dakotas, Iowa, and Illinois.
Rep. Kevin Cramer (R-N.D.) said the Army Corps' decision was a "very chilling signal" for the future of infrastructure in the U.S.
"Roads, bridges, transmission lines, pipelines, wind farms and water lines will be very difficult, if not impossible, to build when criminal behavior is rewarded this way," Cramer said.
