Rosemont Hydrology Method Justification
This technical memorandum discusses the selection of the hydrologic methodology/design storm criteria applied to the proposed Rosemont Copper Project (Project) in Pima County, Arizona. This hydrologic methodology and design storm criteria was also compared to Pima County’s methodology. Although Pima County’s requirements do not apply to mining sites, the comparison was performed in order to confirm Rosemont Copper Company’s (Rosemont) selection of the most practical and protective hydrologic methodology and design storm criteria for use at the Project site.
