If all mining claims in the Grand Canyon region were turned into active mines using the same amount of water as projected by the Canyon Uranium Mine (Canyon Uranium Mine EIS, 1986), the canyon's springs and streams could be decimated, along with all of the plants and animals that depend on the water. Tourism has been the mainstay of the region's economy. On average, 5 million people visit the Grand Canyon every year, making it the key regional economic engine for northern Arizona and southern Utah, adding jobs and driving the growth of small businesses in local communities. Polluting the Grand Canyon with uranium mines and radioactive tailings would have a drastic, negative effect on the area's economic viability. The Grand Canyon is the soul of America's National Park System. To learn more, and to submit a comment by May 4th, go to: http://www.blm.gov/az/st/en/prog/mining/timeout.html.
