Federal environmental regulators have recommended that a planned copper mine in the Santa Rita Mountains near Tucson not be given a permit under the Clean Water Act, AP reports
The U.S. Environmental Protection Agency made its recommendation regarding the Rosemont Mine in a letter sent earlier this month to the U.S. Army Corps of Engineers.
Regional EPA officials say the mine’s proposed activities for mitigating the effects of the operation would not be enough to avoid significant degradation of the aquatic ecosystem.
