The text in the ARARs Tables needs to be modified to <br /> state more precisely which ARARS will be met. <br /> 5. Section 1. 1. 1.2 , Page 1-1 <br /> The text states that the remediation level for OU-1 ground <br /> water will likely be determined by the RWQCB' s <br /> nondegradation policy. However, Section 2 . 2 .4 . 5 states that <br /> "it is doubtful that the nondegradation policy . . . can be <br /> justified as an ARAR . " Further, Section 2 .2 .4 . 4 <br /> adopts the proposed state RPHLs of 2 . 5 µg/L for TCE and 0.7 <br /> µg/L for PCE as the aquifer cleanup levels. <br /> • These sections are not consistent. Please modify the <br /> text in Section 1. 1. 1. 2 to include the determinations <br /> made in the subsequent sections. <br /> 6. Section 1. 2 . 1. 1, Page 1-2 <br /> Figure 1. 2 . -1 identifies the railroad located to the <br /> southeast of the facility as a Western Pacific Main Line <br /> while the text refers to the railroad as Union Pacific <br /> Railroad. <br /> This discrepancy needs to be resolved. <br /> 7 . Section 1. 2 . 4 . 1, Page 1-9 <br /> The FS needs to list all the organic chemicals of concern <br /> from Section 6. 2 . 4 . 1 of the RI in this section. <br /> 8 . Section 1. 2 . 4 . 1, Page 1-9 <br /> Calculations used to derive the quantities listed in Table <br /> 1. 2-2 are essential for demonstrating the accuracy of the <br /> numbers. <br /> Please provide the requested calculations. <br /> 9 . Section 1 . 2 . 4 .4 , Page 1-10 <br /> Figure 1. 2-2 shows that monitoring well LM76 with a <br /> concentration of 19 . 5 gg/L is the well located furthest from <br /> the facility with a TCE concentration of greater than 5 <br /> µg/L. LM76 is located only 2 , 200 feet from the facility' s <br /> boundary. <br /> • The off-site well located 2 , 800 feet from the depot 's <br /> boundary that is discussed in this section needs to be <br /> identified. <br /> 10.
