+ C A M B R I A <br /> r <br /> Site Safety Plan:A Site Safety.Plan will be prepared for the fieldwork. <br /> Monitoring Well Destruction: The three existing onsite groundwater monitoring wells are <br /> proposed for destruction (MW-1 through MW-3). The wells will be pressure-grouted by an <br /> appropriately licensed well driller under the supervision of a Cambria geologist. The well <br /> casings will be filled with neat cement grout from the bottom up. Once the casings are filled <br /> with grout, pressure seals will be placed'on top of the well casings and the well casings will be <br />'i <br /> pressurized. This forces the grout through the well screens out into the filter pack material. <br /> Then the wellhead vault boxes for each well will be removed, an area measuring approximately <br /> two feet in diameter and approximately 3 feet below grade (fbg) will:be excavated,,the well <br /> casings will be cut to a depth of approximately 2.5 fbg; and the remaining.holes will be <br /> backfilled with concrete to grade. <br /> Documentation: Following completion of the well destructions, Cambria will submit a report i <br /> documenting the activities. Department of _ Water Resources ' (DWR) Well <br /> Completion/Destruction forms will be completed for each of the destroyed wells and will be <br /> submitted to DWR under separate cover. <br /> SCHEDULE <br /> Cambria is scheduled to implement well destruction activities on February 24, 2006. A report <br /> documenting the well destruction activities will be submitted after completion of the field work. <br /> i <br /> 0323 2 <br /> 1 <br /> I ' <br />
