S E C O R ---- __ <br /> • System has removed significant SPH. <br /> Rusty then discussed the addition of the soil vapor extraction (SVE)wells to the remedial system <br /> at the site: <br /> • SVE was recently started. <br /> • Start-up sampling and weekly monitoring is underway. <br /> • Due to high concentrations, only 4 wells are currently able to run. <br /> • As site conditions allow, more of the SVE wells will be added. <br /> Robert Traylor asked which wells were currently running. <br /> Dan answered that the four wells were ASVE-1, -2, -3, and -6. All 4 are located under the Delta <br /> View Apartments. <br /> Rusty stated that the next step in ongoing remedial action is the excavation scheduled for <br /> Monday August 29, 2005. <br /> Robert stated that the excavation work scheduled for the Unocal OU is not approved by the RDA. <br /> Mary Serra asked"Why stop remediation that was previously approved by the RWQCB?" <br /> Robert stated that there are no cleanup goals established. <br /> Kitty added, all parties want to do a"Data Gap Assessment"first. <br /> Rusty stated that the L&M Group is prepared to start work on the 29`h and the assessment Kitty is <br /> referring to is separate from the excavation and will not preclude excavation work. <br /> Mary stated that cleanup levels were established in the work plan and asked"To what level and <br /> how Deep?" <br /> Rusty answered to 50 parts per million (ppm)field screened using a photionization detector(PID). <br /> This level was the same as the L&M OU excavation also approved by the RWQCB.Also the <br /> excavation will go to approximately 14 feet below ground surface(bgs).Any product found will be <br /> skimmed during excavation activities. <br /> Robert stated that the L&M OU excavation went to 50 ppm on the PID and "dug up the whole <br /> site." <br /> Tracy stated that the plan is to start Monday, August 29`h and to carry out the RWQCB approved <br /> work plan. <br /> Mary stated that deadlines in letters from the RWQCB are not the same as dates issued in a <br /> cleanup and abatement order.They are, however, a way for RWQCB staff to keep the project <br /> moving forward. <br /> Mary asked"What is the schedule for moving forward?" <br /> 3 <br />
