Review of Predicted Impacts to Aquatic Habitat in Cienega Creek and Empire Gulch

Document ID: 
048927
Year Published: 
2015
Summary: 

The analyses presented by SWCA (2013), and included in the Final Environmental Impact Statement for the Rosemont Copper Project (the Project), attempted to translate predictions of groundwater drawdown as a result of the Project to effects on the aquatic habitat of Empire Gulch and Upper Cienega Creek. These analyses were interpreted by the U. S. Fish and Wildlife Services (USFWS) as evidence that there may be effects to aquatic species as a result of the Project that were not contemplated by the Final Biological Opinion (BiOp). The analyses presented by SWCA (2013) were subsequently used to justify, in part, USFWS’ request for re-initiation of the Section 7 consultation for the Project.
