In order to evaluate soil re-use or disposal options, one 4-point composite soil sample, labeled CS-01-04, was collected from the soil stockpile of the former tank excavation. The soil sample was collected by pushing sample tubes into the stockpile at random locations until each was full. After the soil samples were collected, the ends of the sample tubes were covered with Teflon tape and capped. The soil samples were then appropriately labeled, placed in a cooler with ice, and transported under chain-of-custody protocol to the analytical laboratory. Copies of the chain of custodies are included in Appendix E. 2.3 Sample Analyses The samples were transported and submitted to McCampbell Analytical, Inc., an ELAP-certified laboratory in Pacheco, California. The samples were analyzed for total petroleum hydrocarbons _ as diesel (TPH-D) under EPA method 8015 (modified). The samples were further analyzed for benzene, toluene,ethylbenzene, and xylenes (BTEX) constituents under EPA method 8021B and for methyl tertiary butyl ether(MTBE) under EPA Method 8260B. 2.4 Soil Sample Analytical Results TPH-D was encountered in the analysis of the stockpile sample CS-01-04 at a concentration of 3.8 parts per million (ppm). No other analytes were detected in any of the remaining soil �- samples collected. A copy of the laboratory analytical report is included in Appendix E. The analytical results are summarized in Table 1 and depicted in Figure 3. 3.0 Site Restoration Following completion of the UST removal activities,TAIT backfilled the tank excavation using the soil stockpile and clean imported fill material and then compacted. Site restoration activities were conducted by TArr personnel independent of Shaw oversight. 4.0 Conclusions Based on the field observations and laboratory analytical data presented in this report, Shaw concludes the following: CNMOSHAMusl04-02224m 3
