5. Table 4, DDJC-Sharpe OU 2 Remedial Actions, Page 17 and Figure 3, Operable Unit 2 Remedial Actions, Solid Waste Management Units and Other Areas of Soil Contamination,DDJC-Sharpe: The table shows that SVE systems were installed at 5 sites (i.e., P-IA, P-1B, P-1C, T-1 E, and P-6A); however, based on the figure, an SVE system was also installed at P-8A(although the label next to the SVE system symbol indicates that P-8A is a NFA site). Please resolve this discrepancy. 6. Sections 2.2.2.5, OU 2 Soil Remedial Actions (VOCs), Page 17: The Report refers to a modeling effort which indicated that the impact of the remaining VOC mass in the soil to groundwater will be below ACLs. However, the Report does not 1)provide a reference to a document where this modeling effort is presented and 2) indicate whether this model was approved by the regulatory agencies. Please provide a reference in the Report to a document where the modeling effort is discussed and indicate whether this model was approved by the regulatory agencies. 7. Section 2.2.2.8, OU 2 Soil Remedial Actions (VOCs), Page 17: The Report states that economic evaluations show that SVE operational costs greatly exceed groundwater remediation costs. However, the Report does not 1)provide a reference to a document where these economic evaluations are presented and 2) indicate whether this document was approved by the regulatory agencies. Please provide a reference in the Report to a document where the economic evaluations are discussed and indicate whether this document was approved by the regulatory agencies. 8. Sections 2.2.2.17 and 2.2.2.21, OU 2 Soil Remedial Action (Metals), Pages 19 and 20, and Section 2.2.3.2,Institutional Control Sites, Page 20: In Sections 2.2.2.17 and 2.2.2.21, the Report states that residual concentrations of lead and chromium at Sites S-3 and S-26, respectively, are consistent with U.S. EPA Preliminary Remediation Goals (PRGs) for industrial use, but in Section 2.2.3.2, the Institutional Controls (ICs) discussion does not include Sites S-3 and S-26. Sites with residual concentrations exceeding residential PRGs may require institution of ICs because site risks may exceed those recommended for unrestricted use. For clarity,please indicate why ICs are not necessary for Sites S-3 and 5-26. 9. Section 2.2.3.4, Institutional Control Sites,Page 21: The Report states that Land Use Controls (LUCs) will be implemented for the entire DDJC-Sharpe South Balloon Area south of Crane Way. However, Crane Way is not shown in any of the figures in the Report. For clarity,please include the location of Crane Way in Figures 2 and/or 3. 2
