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.

 Government scientists have gathered data to answer the question of whether a new uranium mining operation will contaminate the Grand Canyon region.

Scientists with the U.S. Geological Survey spent two years collecting and analyzing soil samples from around the Canyon Mine near Tusayan. The study gives them a baseline of the environment they can use to compare with future soil samples.

The mine on U.S. Forest Service land was approved in the 1980s, but ore never was pulled from the ground.

Environmental groups and some elected officials are urging President Obama to create the Greater Grand Canyon Heritage National Monument. A new survey shows statewide support for the proposal that would set aside nearly 2 million acres outside Grand Canyon National Park. Arizona Public Radio’s Ryan Heinsius reports.

A recent poll showed a majority of Arizonans support the possible designation of a national monument outside Grand Canyon National Park. But a group of current and former state wildlife officials have voiced their opposition to the idea. Arizona Public Radio’s Ryan Heinsius reports.

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. 


Federal officials have reached a settlement with a natural gas company over the costs of field work at abandoned uranium mines on the Navajo Nation.

Under the settlement announced Monday, El Paso Natural Gas Company LLC must repay the government about $500,000. The company is the corporate successor to former uranium mine operators near Cameron from 1952 to 1961.

The U.S. Environmental Protection Agency has been working to identify parties responsible for hazardous or potentially hazardous waste.

The Antiquities Act gives the President of the United States power to declare national monuments. A bill sponsored by Republican Arizona Congressman Paul Gosar wants to limit that presidential authority, which has been in place for more than 100 years.

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.

Arizona Congressman Raul Grijalva plans to introduce a bill that would establish a Grand Canyon Heritage National Monument. At a press conference yesterday, he was joined by tribal leaders who say it would protect cultural resources and outlaw uranium mining in the area. Arizona Public Radio’s Ryan Heinsius reports.
