TUCSON, Ariz. (AP) - Federal and state environmental regulators are again butting heads over the Rosemont Copper Mine in the Santa Rita Mountains near Tucson, this time over water protections.

The Arizona Daily Star reports (https://bit.ly/1zFIciA) mine operations require a variety of federal and state permits, and any project impacting water sources needs approval from the U.S. Army Corps of Engineers as well.

Rosemont’s certification process has taken years and seen opposition from the Environmental Protection Agency, a group called Save the Scenic Santa Ritas, and Pima County.

The EPA’s most recent letter was sent to the Corps on April 12 and says the Arizona Department of Environmental Quality approved a water quality permit that leaves many protections for the Cienega Creek and its tributaries unenforced.

Mine officials say ADEQ’s decision is based in science, and that the project doesn’t violate state water standards.
