U <br />Subject: Meeting Notes of November 10, 2005 <br />Date: 12/6/2005 <br />Page 3 of 3 <br />pavement, incorporating the separators and pump island; <br />3) Excavating and removing the two separators; <br />4) Collecting and analyzing soil samples from the two excavations; <br />5) Excavating additional soil if contamination is detected; <br />6) If possible, installing conduits for electricity and pipelines across the excavation for a <br />possible remediation system; <br />7) Backfilling, compacting, and resurfacing once excavation is completed; <br />8) Profiling contaminated soil for transportation and offsite disposal; <br />9) Transporting concrete for recycling; <br />10)Evaluating the analytical data; and <br />11) Preparing a report of separator removal and associated remediation activities. <br />Mr. Henderson suggested that we perform a pilot test to determine whether full-scale <br />implementation of remediation would be effective. He also suggested testing wells separately <br />to evaluate the effectiveness of each. We discussed pilot testing with air sparging coupled with <br />SVE and also considered dual-phase extraction (DPE). As noted above, PSC and ETIC will <br />correlate analytical data with hydrogeologic data and review prior system performance data to <br />evaluate the potential effectiveness of various remedial strategies. From this evaluation, we <br />will develop and propose a remediation plan. ' <br />• After evaluating various remedial approaches, PSC and ET1C will prepare and submit a <br />remediation work plan to SJCEHD for approval. Permitting, installation of the system, start- <br />up, and operation, maintenance, and monitoring would follow. <br />Should you have any questions about this information, please, feel free to contact Paul Anderson <br />at (618) 281-1543 or Tom Neely at (925) 602-4710, extension 17. <br />Respectfully yours, <br />• , &� <br />Paul Anderson <br />PSC -Project Manager <br />LIST OF ATTACHMENTS <br />FIGURES <br />Figure 1.
