in any of the samples. The analytical results are summarized in Table 1 and depicted in Figure 3. <br /> Copies of the analytical reports are included in Appendix E. <br /> 3.0 Site Restoration <br /> ' Following completion of the UST removal activities, TAIT backfilled the excavation using <br /> stockpiled soils and clean imported fill material and then compacted. Reuse of the stockpile was <br /> ' approved by Mr. Catanyag of the SJCEHD, based on analytical results. <br /> ' Site restoration activities were conducted by TAIT personnel independent of IT oversight. <br /> ' 4.0 Conclusions <br /> Based on the field observations and laboratory analytical data presented in this report, IT <br /> concludes the following: <br /> • On April 29, 2002, following emptying and rinsing, the 2,000-gallon diesel UST <br /> and associated piping were removed and transported off-site for disposal. <br /> 1 . No soil staining or petroleum hydrocarbon odors were observed within the tank <br /> excavation or fill material during tank removal activities. <br /> • Groundwater was not encountered within the excavation. <br /> • Results of the laboratory analyses encountered TPH-D at a concentration of 4.4 <br /> ' ppm in the composite sample collected from the soil stockpile. <br /> • No TPH-D or BTEX constituents were encountered in the soil samples collected <br /> from the tank excavation or pipeline trench. <br /> ' • The excavation was subsequently backfilled using stockpiled soils and clean <br /> imported fill material, as approved by the SJCEHD. <br /> • No further action is warranted for this site. <br /> CNCD\06-25-02\SHARE\UST102-0057.doc <br />' 4 <br />
