D.1 Introduction

This Attachment D has been prepared in support of an Application by Florence Copper, Inc. (Florence Copper) to the United States Environmental Protection Agency (USEPA) for issuance of an Underground Injection Control Class III (Area) Permit (UIC Permit) for the planned Production Test Facility, to be located at the Florence Copper Project property in Pinal County, Arizona. As required for Attachment D of USEPA Form 7520-6, this Attachment includes maps and cross sections that depict the vertical limits of all underground sources of drinking water (USDWs) within the Area of Review (AOR) defined in Attachment A of this Application. Figures D-1 and D-2 show the location of regional and site scale cross sections, respectively. Figures D-3 and D-4 are regional scale cross sections. Figures D-5, D-6, D-7, D-8 and D-9 are site scale cross sections depicting the FCP property. Pink shading depicted on cross sections D-3 through D-9 indicates the extent of USDWs outside of the AOR and Aquifer Exemption boundary.

Figure D-10 is a map showing the location of cross sections through the PTF well field. Figures D-11 and D-12 are cross sections through the PTF well field. Blue shading in Figures D-11 and D-12 indicates the extent of USDWs outside of the AOR and Aquifer Exemption boundary.
