If you have not already uploaded the work plan, please make the <br /> following corrections to the work plan prior to uploading it. <br /> Table 1, you indicate that there was no contamination in soil and groundwater collected from MW-3R. This is not <br /> correct. Contamination was found in both soil and groundwater from MW-3R and this well must be drilled out, not <br /> pressure grouted. (Also, DPE10 (s) did not have contamination in the soil samples.) <br /> Figure 1 is not included in the work plan, but Figure 3 is and it is difficult to read this well location map. <br /> Figure 2 illustrates that cement/bentonite slurry will be used but the narrative states that neat cement will be used <br /> to grout the annular seal. Please use neat cement and correct Figure 2. <br /> You did not mention using a tremie pipe, nor did you mention what pressure will be applied, nor the length of time <br /> the pressure will be applied when pressure grouting. <br /> I have reviewed previous reports and was able to find documentation for all wells except MW-10 and MW- <br /> 11 stating that eight-inch augers were used when installing the wells. (You can use eight-inch augers to <br /> destroy wells that were installed using eight-inch augers.) <br /> Please revise the work plan to include this information. <br /> Thank you, Javad. <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: vmccartneva-sicehd.com <br /> 04 -- <br /> From: Javad Masoudi [mailto:jmasoudi@emscorp.us] <br /> Sent: Friday, March 28, 2014 3:10 PM <br /> To: Vicki McCartney [EH] <br /> Cc: GOsterkamp@osterkampgrp.com; DZumberge@hotmail.com <br /> Subject: RE: work plan for groundwater remediation at Frontier Transportation Facility in Tracy <br /> Hello Vicki, <br /> Attached is the proposed well destruction method for your review and comment. We will apply <br /> for and obtain all permits necessary for this work after receipt of your approval of this destruction <br /> method. <br /> For cost saving purposes, we will plan to do all construction work in one mob/demob event. <br /> 4/4/2014 <br />
