Flow and direction in the various can time is influenced change over by pumping from aquifers such as for irrigation The area of the aquifer other nearby field that Curis will use wells in is not generally used for irrigation and for ISCR thus follows the natural operations gradient towards the northwest and away from the Gila River of the Town The Management Area and hence is within the of Florence project site Designated by the Town if needed be is also noted wastewater should that with the proposed regulated along It WWTP and Anthem are proposed be Ranch Ranch there wells to for Merrill utilized at Merrill is not addressed development This item specifically The Florence Copper currently has an on-site wastewater treatment with Project septic facility to ADEQ and for permit transfer has been submitted and tank leach is in field request at this time process Town of Florences Emergency and services related include Plans Emergency to this Response project Plan hence of emergency Multi-Jurisdictional Multi-Hazard the services Mitigation are yet ability unknown in response be to potential emergency situations the Project site This item should at revisited with services personnel emergency for both the and full commercial Agreed ISCR ISCR During planning test production preparedness and will be thoroughly operations studied in close emergency response Town consultation with of Florence personnel General Plan Amendment The proposed may affect water quality and the to sustain quantity ability demands of near may exist for water quality and future residents pending alterations that quantity have been and funded be that planned This item should revisted Water used will be That said in the ISCR at the Florence Copper process Project recycled to 20% more water will be pumped 10 back approximately out of the aquifer than is recycled it through to maintain into the injection wells This permit condition that is required is water to be consumed by The 10 to 20 control of all injected solutions hydraulic of surplus amounts to about 1300 water ISCR acre This is intensive use operations feet per year less the same than agricultural on land base development the that hosts the In addition aquifer is not generally used for potable water used by Florence water Potable Copper orebody Project the Town the upper is separated from of Florence within upper the aquifer This aquifer is the orebody 20 40 foot natural that hosts by This clay layer prevents aquifer clay layer mixing of the two As such water quality nor water quantity neither for current aquifers or Town domestic uses will be of Florence by the Florence Copper future affected Project RESOURCES ARIZONA USA CURlS INC Hunt Florence Arizona 85132 1575 Highway florencecopperproj ect.com SWVP-019244
