Y <br /> II cement into the well. The well casing will be sealed and a pressure of 25 pounds per <br /> square inch will be applied for a minimum of 10 minutes to allow the grout to infiltrate <br /> into the filter pack. After the cement has set, the vault box for each well will be <br /> removed, and a hole 1 foot larger in diameter than the original borehole will be <br /> excavated to a depth of approximately 3 feet below grade (fbg). The well casing will be <br /> cut off 2.5 fbg (6 inches above the bottom of the excavation). The well will then be filled <br /> with grout and the grout will be allowed to spill over the top of the casing and fill the <br /> hole to a thickness of 1 foot (6 inches above the well casing). The hole will then be <br /> backfilled with soil and capped with concrete, asphalt patch, or soil to match the <br /> surrounding grade. <br /> 2.5 REPORT PREPARATION <br /> After the field activities are completed CRA will generate a report documenting the well <br /> destructions and submit it to the EHD and RWQCB. <br /> 2.6 SCHEDULE <br /> CRA will schedule the field work to occur within 45 days of receiving RWQCB staff <br /> approval of this work plan and receipt of the NFA letter. Well destruction permits and a <br /> C-57-licensed drilling contractor will be obtained prior to starting this work. <br /> 060222(14) 2 CONESTOGA-ROVERS&ASSOCIATES <br />
