Rosemont Mine's water permit upheldPosted: Updated:
An administrative judge has ruled that opponents have failed to prove that a proposed new open pit mine near Tucson would harm groundwater supplies.
The Arizona Daily Star reports that Law Judge Thomas Shedden upheld last week the Rosemont Mine's aquifer protection permit from the state. He said opponents didn't show that the Arizona Department of Environmental Quality's granting of the permit was "arbitrary, unreasonable, (or) unlawful".
The permit allows Rosemont Copper Co. to discharge materials if it can show that it's using the best-known technology to prevent pollutants from reaching groundwater.
Shedden's ruling dismisses 19 issues raised by 11 individuals and five environmental groups opposing the proposed mine. They contended the state permit will allow Rosemont Copper to pollute local groundwater supplies.
