Hudbay Minerals’ primary mitigation project needed to obtain the federal Clean Water Act permit necessary to construct the $1.9 billion Rosemont Copper Mine is based on a misleading scientific analysis and fails to offset for the loss of desert aquatic resources that would be destroyed by the massive open-pit mine, according to an analysis by a leading expert on rivers and wetlands.
G. Mathias Kondolf, a University of California Professor of Environmental Planning and an internationally-known expert on hydrology and river restoration, prepared the report for Save the Scenic Santa Ritas, a Tucson-based conservation group opposed to the Rosemont mine. SSSR released the report in a Jan. 4 press release.
Kondolf’s Dec. 29, 2017 report was submitted to the U.S. Army Corps of Engineers, which is currently reviewing Hudbay’s application for a Section 404 Clean Water Act permit needed to construct the massive open-pit mine.
The Corps cannot legally issue the 404 permit unless Hudbay provides sufficient mitigation to compensate for the destruction of aquatic resources in the Cienega Creek watershed that will result from construction of the mile-wide, half-mile deep open pit and dumping of waste rock and mine tailings on more than 2,500 acres of the Coronado National Forest.
The Corps’ Los Angeles district office recommended denying the permit in July 2016, in part, because Hudbay failed to provide adequate environmental mitigation. The Corps’ San Francisco regional office is currently reviewing Hudbay’s application. Continue reading
