Groundwater displaced by destruction <br /> activities will be contained and disposed of properly. The wells were constructed with <br /> 4-inch diameter PVC well casing to total depths ranging from 26-28 feet bsg. The <br /> boreholes for the wells were originally drilled with 10-inch augers; therefore 10-inch <br /> augers must be used for the destruction. <br /> SJC/EHD approves the proposed destruction of the monitoring wells. Please proceed <br /> with submittal of a SJCIEHD well destruction permit application, required $60.00 permit F <br /> fee and with scheduling the approved work. If you have any questions please call Lori <br /> Duncan at (209) 468-0337. <br /> Donna Heran, REHS, Director <br /> Environmental Health Department <br /> I <br /> Lori Duncan, Senior REHS Margar Lagorio, REHS <br /> LOP/Site Mitigation Unit IV Program Coordinator Unit IV <br /> F <br /> t <br /> cc: James Barton, CVRWQCB 4 <br /> Rusty Benkosky, Secor International Inc. <br /> l <br /> } <br /> i <br />
