Response to Comments Regarding Groundwater Flow Modeling for the Rosemont Project

A response to the May 3, 2012 letter from Coronado National Forest (CNF) concerning their review of documents submitted in support of groundwater impacts for the Rosemont Environmental Impact Statement (EIS). The two issues raised in the letter include: (1) a request for groundwater level change hydrographs at 15 model domain locations depicting the projected upper and lower bounds of change for predictive sensitivity analyses conducted using the Rosemont Mine model and presented in the August 30, 2010 Montgomery & Associates (M&A) report; and (2) a request for additional documentation of the western model boundary to support model defensibility.
