Court rebuffs enviros, allows motorized rafts at Grand Canyon

An appeals court on Tuesday rejected a challenge by environmentalists to federal rules allowing the use of motorized rafts at the Grand Canyon. Several environmental groups sued the National Park Service in 2006 over its Colorado River Management Plan, which permits the use of motorized rafts in the canyon. The groups argued that the park service ignored its own rules and policies that say canyon uses shouldn't impair the wilderness character of the area. In rejecting that argument, the 9th U.S. Circuit Court of Appeals in San Francisco upheld a lower court's decision that said the plaintiffs failed to show the park service acted arbitrarily and capriciously when it adopted its river management plan...AP
