Draft Final Site-Wide ROD -5- 26 January 1998 <br /> DDJC Tracy <br /> 15. Section 9.7.8.3. Ground water has not been evaluated at this site; therefore, the fifth sentence in this <br /> section which states "None of the CoCs has been detected in ground water near the site." is misleading <br /> and should be deleted. <br /> 16. Section 9.7.8.4. The second sentence in this section limits the continued ground water monitoring <br /> to be conducted as part of the selected remedy for Drum Storage Area- Building 30. This is inconsistent <br /> with Section 9.1 of the ROD. This sentence should be deleted. <br /> 17. Section 9.8.1.4. This section indicates that the cleanup levels for soil at S WMUs 2 and 3 are based, <br /> in part, on results obtained during the 1997 excavation activities conducted to complete the EE/CA <br /> removal action at the former Sewage and Industrial Lagoon sites. The ROD should include a technical <br /> memorandum which describes the activities conducted, and presents the analytical results and rationale <br /> used in modifying cleanup levels presented in the RI/FS. <br /> 18. Appendix C. The reporting limits should be provided as part of the results presented for the <br /> additional analysis performed using a deionized water leaching procedure to determine the potential <br /> solubility of target analytes at SWMU 4. <br /> We are available to discuss our comments. We look forward to finalizing the ROD. If you have any <br /> questions, please contact me at (916) 255-3065. <br /> n �►� <br /> Karen Bessette <br /> Project Engineer <br />
