"If you can't stop mining at the Grand Canyon, where can you stop it?" asked Richard Wiles, executive director of the Environmental Working Group.
The energy-versus-environment debate is apparent within the Interior Department, which granted the mining claims through its Bureau of Land Management. Among the mining critics is Steve Martin, superintendent of the Grand Canyon park and an Interior Department employee himself. "There should be some places that you just do not mine," Martin said.
Uranium is "a special concern," he added, because it is both a toxic heavy metal and a source of radiation. He worries about uranium escaping into the local water, and about its effect on fish in the Colorado River at the bottom of the gorge, and on the bald eagles, California condors and bighorn sheep that depend on the canyon's seeps and springs. More than a third of the canyon's species would be affected if water quality suffered, he said.
Martin is not the only one uneasy about potential water contamination. Add to the list the Metropolitan Water District of Los Angeles, which sells wholesale water throughout Southern California from its Colorado River Aqueduct. "In addition to the public health impacts, exploration and mining of radioactive material near a drinking water source may impact the public's confidence in the safety and reliability of the water supply," the district's general manager, Jeffrey Kightlinger, wrote in March to Interior Secretary Dirk Kempthorne.
No one is mining near the Grand Canyon yet, but wooden claim stakes can be spotted throughout the brush-covered plains north and south of the park.
Vane Minerals, a British company, applied last year to start exploratory drilling on seven sites in the Kaibab National Forest, near the canyon's popular South Rim.
Under current mining law the Forest Service had no choice but to allow the drilling, Regional Forester Corbin Newman testified in March to Congress. The mission of a national forest is different from that of a national park, he pointed out. Indeed, signs at the Kaibab Forest's border proclaim that visitors are entering the "Land of Many Uses."
In response to the approval, the Grand Canyon Trust, the Center for Biological Diversity and the Sierra Club sued in federal court, alleging that the Forest Service didn't thoroughly investigate the environmental effect of drilling and prospective mining. In April, a judge issued a temporary restraining order until the case could be heard, probably in the summer.
