BISMARCK, N.D. (AP) - Two American Indian tribes in the Dakotas that are fighting the Dakota Access pipeline in court are making a renewed push to bolster protections for their water supply.
The Standing Rock and Cheyenne River Sioux have filed court documents urging a federal judge to reject the recent arguments of federal officials and the pipeline developer that the tribes' proposals aren't needed.
The Army Corps of Engineers is conducting an additional court-ordered review of the pipeline's impact on tribal interests. While that's done, the tribes want additional protections such as emergency equipment staging at the pipeline's Lake Oahe crossing on the Missouri River, which is their water source.
The Corps and pipeline developer argue that additional protections would be unwarranted and burdensome.
It's not known when the judge might rule.
