Tevine-Fricke-Recon <br /> ENGINEERS.HVDROGEOLOGISTS 8 APPLIED SCIENTISTS <br /> 2. The RI Source Investigation report will be submitted in January 1998. The Sequence 5 soil borings and Sequence 6 well <br /> installation activities will now be conducted as part of the Phase II IRA instead of the RI Source Investigation. <br /> LFR acknowledges this statement. <br /> 3. The proposed locations for the Sequence 5 soil borings and Sequence 6 well installations will he presented to staff in the <br /> Phase II IRA workplan. <br /> Recommendations for Sequence 5 soil borings and Sequence 6 monitoring well installations (if <br /> necessary) will be presented to the RWQCB in the draft Interim Source Area Remedial <br /> Investigation report, and further discussed in the draft Phase H IRA Work Plan. <br /> 4. Additional field work, beyond that described in the September 1996 Work Plan for Environmental Investigation, will be <br /> conducted as part of the Plume Perimeter Investigation. Proposed locations for well installation and CPT locations shall <br /> be submitted to staff in January 1998. <br /> LFR acknowledges this statement. <br /> 5. We agreed that LFR may collect an in-situ groundwater sample from the C zone upgradient of MW-30 in lieu of placing <br /> an additional monitoring well in this location. <br /> LFR acknowledges the RWQCB's approval for LFR to collect an in situ groundwater sample from <br /> the C zone, upgradient from MW-30. The specific location and procedures for collecting the in <br /> situ groundwater sample will be provided to the RWQCB in the proposal for additional field work <br /> for the Plume Perimeter Investigation to be submitted in January 1998. <br /> 6. As discussed, LFR will provide one master list of all deliverables(including items completed as part of the remedial <br /> investigation, health risk assessment,treatability study, feasibility study,and interim remedial actions) before the 2 <br /> December 1997 monthly meeting. <br /> A draft schedule of milestones and draft project schedules were submitted to Ms. Wyels and LPL <br /> on November 24, 1997. We discussed these items with Ms. Wyels and LPL on December 2, 1997 <br /> during our Periodic Meeting. We have incorporated all comments and have attached the revised <br /> schedules and milestones to this letter. These project schedules will be updated periodically, as <br /> necessary. <br /> ADDITIONAL SOIL VAPOR LOCATIONS (10 NOVEMBER 1997) <br /> The locations are approved. <br /> Four additional soil-vapor locations were sampled on December 5, 1997. The results of this <br /> additional investigation were faxed to Ms. Wyels and to LPL on December 11, 1997. <br /> Lt-Resp-RWQCB-Dec97-041 1 1:SRL 9 <br />
