The well will <br /> then be excavated to appro imately 3 feet below surface grade (bsg). The top 2.5 feet of <br /> the well casing will then be cut and removed and grout will be used to FII the boring to <br /> approximately 0.5 feet above the top of the well casing. The remaining borehole will be <br /> backfilled to surface grade with neat cement and covered with dirt and aggrate road base <br /> for construction. <br /> Upon completion of field work and disposal of soil-cuttings, a well destruction report <br /> describing well destruction activities and procedures,will be prepared and submitted to the <br /> EHD. <br /> If you have any questions or require further information, please contact our office at (209) <br /> 467-1006. <br /> Sincerely, <br /> Advanced GeoEnvironmental, I FtiSs�oNaL sEo�o <br /> No. 7473 <br /> William R.
