The Havasupai Tribe and a coalition of conservation groups praised the decision Tuesday by the U.S. 9th Circuit Court of Appeals to uphold the Department of the Interior's 20-year ban on new uranium mining claims across 1 million acres of public lands adjacent to the Grand Canyon.
The court ruled that the ban, adopted in 2012, complies with the Constitution and federal environmental laws, and that the protected area was not too large, as plaintiff mining companies had argued. The ban protects the aquifers and streams that feed the Colorado River and the Grand Canyon from toxic uranium-mining waste pollution and water depletion.
