A court has ordered the Dakota Access Pipeline to shut down, delivering a victory for tribes that have opposed it.
Judge James Boasberg on Monday ruled that the pipeline has to be shut down within 30 days while the Army Corps of Engineers works to prepare an environmental impact statement for a rule relaxation that allowed it to cross the Missouri river.
The court had ruled already that the U.S. Army Corps of Engineers had violated environmental laws when it gave Dakota Access an easement to construct a segment of the pipeline.
The new decision determined that the easement should be overturned while the government works to rectify this.
“Clear precedent favoring vacatur during such a remand coupled with the seriousness of the Corps’ deficiencies outweighs the negative effects of halting the oil flow for the thirteen months that the Corps believes the creation of an [environmental impact statement] will take,” wrote Boasberg, an Obama appointee.
The Standing Rock Sioux Tribe has sued over the controversial pipeline, which crosses native lands and has drawn protesters from across the country. The 1,200-mile project carries oil from North Dakota to Illinois.
Meanwhile, the Trump administration is working to roll back part of the National Environmental Policy Act, on which Boasberg’s decision was based. The law requires environmental review of projects like pipelines.
The Monday decision follows the recently announced cancellation of the separate Atlantic Coast Pipeline, which would have carried natural gas from West Virginia to North Carolina.
