We concur with your proposal. <br /> Vicki McCartney, Senior REHS <br /> San Joaquin County <br /> Environmental Health Department <br /> 1868 East Hazelton Avenue <br /> Stockton, California 95205 <br /> Phone: (209)468-9852 <br /> Email: vmccartne sicehd.com <br /> x <br /> From: Vicki McCartney[EH] <br /> Sent: Thursday, March 27, 2014 10:18 AM <br /> To: 'Magee, Amanda' <br /> Cc: Adrienne Ellsaesser [EH] <br /> Subject: RE: 7-11 #20632, 4627 DaVinci Drive, Stockton <br /> Hi Amanda, <br /> have discussed Stantec's proposal to pressure grout MW-4R with Adrienne Ellsaesser, Program Coordinator. <br /> Instead of destroying MW-4R by.pressure grouting, please destroy MW-4R as follows: <br /> Insert an additional Schedule 40 casing at least eight-inches larger in diameter than the outside diameter of the <br /> present casing of MW-4R to total depth of fifteen feet below surface grade (bsg); if the pea gravel extends beyond <br /> fifteen feet bsg, then extend the casing to the total depth of the pea gravel. This should contain the pea gravel <br /> and prevent the pea gravel from entering the area around MW-4R. Drill out MW-4 as originally proposed and <br /> grout the borehole with near cement grout to the surface while removing the outer casing. <br /> I have fieldwork today and will be leaving the office around 10:50 a.m. You can reach me on my cell phone <br /> at(209)481-9257 if you have any questions. <br /> Thanks, Amanda. <br /> Vicki McCartney, Senior REHS <br /> San Joaquin County <br /> Environmental Health Department <br /> 1868 East Hazelton Avenue <br /> Stockton, California 95205 <br /> Phone: (209)468-9852 <br /> Email: vmccartney(c sicehd.com <br /> 3/27/2014 <br />
