Opponents of the proposed Rosemont Mine have filed suit, seeking to overturn a state decision awarding a groundwater protection permit to mine owners Rosemont Copper Co.
The permit allows the company to discharge materials if it can show it’s using the best available technology to keep pollutants from reaching groundwater.
The suit, filed last week by 14 individuals and groups, challenges the July decision by the State Water Quality Appeals Board to uphold issuance of the permit by the Arizona Department of Environmental Quality in April 2012.
