Prior to drilling activities, each proposed drilling <br /> location will be clearly marked and an utility clearance obtained through Underground <br /> Service Alert. <br /> Prior to destruction activities, all wells will be checked for total depth and integrity using a <br /> Solinst water level meter. Any obstructions found in the well will be removed. <br /> Wells MWAA, MWA B, MW-3 through MW-7,and OW-1 through OW-10 will be drilled-out <br /> to one foot deeper then the total depth of the well utilizing 8.25-inch diameter hollow-stem <br /> augers, and well MW-2AlB will be drilled-out to one foot deeper then the total depth of the <br /> well utilizing 10.25-inch diameter hollow-stem augers(10-inch diameter boring).All original <br /> well construction materials will be removed (including well casing, screen, filter pack, and <br /> annular seal) to ensure that no residual contamination is sealed within the abandoned <br /> borehole. Remaining boreholes will be backfilled to surface grade with neat cement and - <br /> covered with concrete or asphalt, depending on the surrounding surface material. <br /> Soil cuttings generated during drilling activities and rinseate will be containerized in <br /> properly labeled Department of Transportation (D.O.T.)-approved 55-gallon drums or a <br /> landfill disposal container, and stored on-site for proper disposal. <br /> Upon completion of field work and disposal of soil-cuttings, a well destruction report <br /> describing well destruction activities and procedures, including documentation of waste <br /> disposal from well destruction'and other activities will be prepared and submitted to the <br /> SJCEHD and CVRWQCB. <br />
