The Arizona Department of Environmental Quality is developing new air pollution permits for three uranium mines near the Grand Canyon. The agency halted the permit renewals last year after elevated levels of uranium were detected near one of the mines. Arizona Public Radio’s Ryan Heinsius reports.

The U.S. Environmental Protection Agency has released its final plan to monitor contamination levels from last summer’s Gold King Mine spill in Colorado. The plan is designed to give the agency broad scientific data about conditions in the Animas and San Juan rivers, which bore the brunt of the spill. Arizona Public Radio’s Ryan Heinsius reports. 


Westerners used to use all kinds of markers to identify the locations of mining claims, such as wooden posts and large stone cairns. The modern way is easy: sink an un-capped PVC pipe into the ground. It’s easy and effective. But there’s a dark side to these innocuous plastic tubes.

State environmental officials have suspended the air-pollution permit renewal process for three uranium mines near the Grand Canyon. Recent tests showed uranium content in the soil near one of the mines is four times higher than previously measured. Arizona Public Radio’s Ryan Heinsius reports.

Environmental groups say three mines near Grand Canyon National Park pose a significant threat to public health and the canyon’s ecology. The groups want state officials to deny the mines’ air-pollution permits, which are up for renewal. Arizona Public Radio’s Ryan Heinsius reports.

Nuclear power has gained more attention as a clean energy source. The raw material needed to make that power is uranium; and the highest-grade uranium deposits in the nation are near the Grand Canyon. The federal government has halted new uranium mining in the region, but old mines can still reopen.
