A federal appeals court has ruled against conservationists and tribes in their challenge of a uranium mine north of the Grand Canyon.
The group had sued the U.S. Bureau of Land Management, alleging the agency relied on an outdated and inadequate environmental analysis in allowing the Arizona 1 Mine to resume operation.
The 9th U.S. Circuit Court of Appeals ruled Monday that the BLM hasn't made any decisions that would trigger a new analysis and that the 1988 operation plan allows for temporary closures.
The debate is expected to arise again as companies seek to resume mining near the Grand Canyon. Previous mining operations in the area ceased some 20 years ago.
The Arizona 1 Mine was the first to resume. Its owner, Energy Fuels Inc., plans to restart others.
