WASHINGTON – A proposal for a massive open-pit copper mine in the Santa Rita Mountains will be back in court this month as opponents challenge permits for the project, the latest twist in an 11-year battle over the Rosemont Mine.
The fight pits supporters – who say the mine has been studied to death and will bring much-needed jobs to Pima County – against opponents, who see a flawed review process on a mine in “the absolute worst place” for environmental and public health threats.
It comes as Hudbay Minerals awaits approval of what could be the final step in getting approval for the mine, the Army Corps of Engineers’ issuance of a Section 404 permit. That permit is named for a section of the Clean Water Act regulating the discharge of fill material into waterways.
“The regulatory process that we have is, from the outside, very time-consuming,” said Mike Petersen, public affairs officer for the South Pacific Division of the Corps, but it’s necessary to make a decision that balances “reasonable development of commerce” with water quality.
A previous version of this story incorrectly identified the office of the Army Corps of Engineers’ Mike Petersen. He is the public affairs officer for the South Pacific Division of the Corps. The story has been corrected, but clients who used earlier versions should run the correction found here.
“There’s a lot of information and a lot of considerations we have to take into account,” Petersen said. “We want to make the most informed decision that we can stand behind.”
But while that decision is pending, at least three lawsuits are proceeding that attack earlier environmental permits issued for the mine.
Those suits – one by the Center for Biological Diversity, one by a group called Save the Scenic Santa Ritas and one by the Pascua Yaqui, the Tohono O’odham and the Hopi tribes – are expected to be in court this fall. They charge that earlier reviews by the Forest Service and the Fish and Wildlife Service did not adequately consider the mine’s likely impact on environmental and cultural resources.
Stu Gillespie, a staff attorney with Earthjustice, which is representing the tribes in their suit against the Forest Service, said the service’s recommendation did not go far enough.
“One of our main arguments is that final environmental impact statement and the record of decision by the forest supervisor is that he failed to adequately analyze alternatives,” Gillespie said.
In an emailed statement, Hudbay said the “project has been going through a thorough evaluation” and that the Forest Service set “specific mitigation and monitoring requirements” to ensure the impacts of the mine are measured.
“Any questions asked about the Final EIS impact analysis are a moot point at this time as they have been managed and responded to by the agencies responsible,” said a Hudbay spokeswoman. “The Rosemont Project has gone through this review under the … highest level of review required by the federal government.”
The Department of the Interior, Bureau of Land Management, the Forest Service and Fish and Wildlife Service would not comment on the status of the mine. Tribal officials also did not respond to requests for comment.
The proposed open-pit copper mine would be about 6,500 by 6,000 feet – more than a mile wide in each direction – with a final depth up to 2,900 feet, according to the Forest Service’s final environmental impact statement on the Rosemont project. Of the 1.96 billion tons that would be excavated from the site, about 700 million tons would be ore and the remaining 1.2 billion tons would be waste rock.
The mine would be in operation from 24 to 30 years, generating an estimated $136.7 million in state and local taxes while creating a projected 434 direct jobs and 1,260 indirect jobs per year in Pima County alone, the Forest Service report said.
“It would just be a shame if projects as consequential as this were to take on some sort of partisan coloring,” said Garrick Taylor, the senior vice president for government and communications at the Arizona Chamber of Commerce.
He noted that 17 government agencies have a hand in approval of the permit.
“We believe it’s still a worthwhile project and will do tremendous good for the region and the state,” Taylor said. “Copper mining is incredibly important to the legacy of the state.”
But critics say no amount of economic benefit can outweigh the potential environmental damage of the mine.
“It is the absolute worst place you could pick to put an open-pit copper mine in terms of all the impacts to endangered species, threats to Tucson’s water supply and all these other issues,” said Randy Serraglio, a conservation advocate with the Center for Biological Diversity.
Rep. Raul Grijalva, D-Tucson, said that while Hudbay talks about the economic benefits of the mine, “it ignores its negative environmental impacts that will cause irreparable damage to wildlife habitats, water quality, and land.”
“The health, well-being, and cultural needs of Southern Arizona’s residents should always come before the profits of a mining company,” Grijalva said in an emailed statement.
Fred Palmer, a senior fellow at the Heartland Institute, said he believes that the pros of the mine outweigh its cons on this site, which is federal land sitting on a “terrific” copper deposit.
“It’s inherently within the public interest that this deposit be developed, notwithstanding the protestations from the tribes, who I deeply respect and the environmental community,” he said.
But Gayle Hartmann, president of Save the Scenic Santa Ritas, said the value of the Coronado National Forest, where the mine would be located, is too great to risk.
“This is a beautiful place that has natural attributes … including streams, wildlife, beautiful oak trees, places to camp, a scenic route along the eastern side of the Santa Rita Mountains that people in southern Arizona have enjoyed for centuries,” Hartmann said.
“That value is much, much greater than anything that could come from an open-pit mine,” she said.
