Florence Copper applied for this permit with the EPA to begin operating a non-commercial, test in-situ copper mine on State Trust land adjacent to Hunt Highway in the geographic center of the Town of Florence, involving the injection of large quantities of sulfuric acid directly into the groundwater surrounding the copper deposit.   The Town of Florence and the Florence Town Council remain opposed to the test project based, in part, on the likelihood of the mine polluting the Town’s water supply when sulfuric acid is injected directly into a large water aquifer that is used to provide water to neighboring homes and businesses, and which is critical to the future growth of the Town.   

Florence Copper needs permits from both the EPA and the Arizona Department of Environmental Quality (ADEQ) before they can begin injecting acid into the Town’s groundwater.  ADEQ previously issued an Aquifer Protection Permit (APP), which was nullified by the State Water Quality Appeals Board in November upon the recommendation of a judge who, following a six week hearing, found that Florence Copper’s claims supporting the APP were largely unsupported.  Florence Copper must resubmit its application for an APP to ADEQ addressing, among other things, the deficiencies found by the judge and adopted by the Water Quality Appeals Board.  ADEQ must hold a public hearing and solicit public comment in the upcoming months as part of that process. 

It is important to clarify and emphasize that neither EPA nor ADEQ have issued or will necessarily issue the permits, and any claim or implication to the contrary is wrong or misleading.
