Each well cover box will <br /> be removed and the well will subsequently be over-drilled to a depth of approximately 3 to 5 feet <br /> bsg. The over-drilled section will then be filled to surface grade with portland cement. Asphalt patch <br /> may alternatively be used at the surface to match the surrounding pavement. <br /> The piping extending under the current USTs was installed in the pea gravel underlying the tanks. <br /> Therefore, bentonite chips will be used to form a nl,» at+.l,F• tease of lhte �fe*r.r.�1 n=n;ru Tkr ur r<ira` <br /> piping wiil then be liked to surface grade with portland cement. <br /> If you have any questions or comments, please contact our office at (209) 467-1006. <br /> Sincerely, <br /> Advanced GeoEnvironmental, Inc. <br /> RI-t <br /> Kevin McKibben <br /> Senior Staff Geologist <br /> Enclosures <br /> cc: Mr. Robert Phillips <br /> Advanced GeoEnvironmental,Inc. <br />
