Oil will start flowing through the Dakota Access Pipeline as early as next week after an appeals court refused to grant an emergency order to Native American tribes that would halt the oil delivery process.
The brief court filing late Monday from Dallas-based Energy Transfer Partners didn't detail the attacks, but said they "pose threats to life, physical safety and the environment".
"These coordinated attacks will not stop line-fill operations", Dakota Access attorneys wrote.
A spokeswoman for the company declined to elaborate on the types of attacks.
"The courts' consistent support of the pipeline in these proceedings is the result of the company's and Army Corps of Engineers' dogged compliance with all applicable laws and regulations", said MAIN spokesperson Craig Stevens.
The company has maintained the pipeline, which will move oil from North Dakota's Bakken oil field more than 1,000 miles across four states to a shipping point in IL, will be safe.
Several tribes, particularly the Standing Rock Sioux Tribe, but also the Yankton Sioux, Oglala Sioux and Cheyenne River Sioux-who make up part of the Oceti Sakowin or Great Sioux Nation-have looked to the courts to stop the $3.78 billion project in separate lawsuits, four of which have been combined, reports the AP.
In their legal argument, the Native American tribes claimed that the pipeline under Lake Oahe would desecrate water used in sacred ceremonies.
The US Court of Appeals for the District of Columbia Circuit ruled on Saturday that the tribes had not met the requirements for the order to be issued. The stretch under the Missouri River reservoir is the last piece of construction for the pipeline.
Judge Patrick Millett, concurring with the denial of the two other judges on the court of appeals panel, Brett Kavanaugh and Robert Wilkins, noted that the tribes' basis for seeking an injunction was tied exclusively to the Religious Freedom Restoration Act (RFRA), even though the district court had yet to decide whether it was going to allow the RFRA claim in the case. Judge Boasberg has said he doesn't think the tribes have a strong case on appeal. The company has said it will begin operating the pipeline as soon as its route is completed.
