SECOR <br />ConocoPhillips <br />76 Service Station #05447 (Former BP 11191) <br />March 15, 2004 <br />Page 2 <br />SOIL ANALYTICAL RESULTS <br />TPHd was reported in soil samples D-3@3' and T-1 @3' at concentrations of 13 mg/kg and 30 mg/kg, <br />respectively. All other analytes were reported as not detectable above the laboratory reporting limits. <br />Soil analytical data is summarized in Table 1. Locations of the samples are shown on Figure 2. Field <br />and laboratory procedures are included as Attachment A. Certified analytical laboratory reports and <br />chain -of -custody documentation are included as Attachment B. <br />STOCKPILED SOIL <br />All pea gravel removed during the sampling phase of work was reused to backfill the existing <br />trenches. <br />CONCLUSIONS AND RECOMMENDATIONS <br />Based on the results of soil sampling during the dispenser upgrade, minor detections of TPHd was <br />noted in samples D-3 and T-1. Based on the above information no additional assessment appears <br />warranted in the area of the product dispensers at this time. <br />If there are any questions, please call us at (916) 861-0400. <br />Sincerely, <br />SECOR International, IncorporatedE� <br />411f ;/O� //� <br />Clinton Harms <br />a� <br />Project Scientist �`� <br />EW 12/31/08±- <br />Rust Benko�ky, P <br />OF CA `��O <br />Senior Engineer <br />cc: Mr. Bill Borgh, ConocoPhillips <br />Mrs. Liz Sewell, ConocoPhillips <br />Mr. Kyle Christie, BP <br />Attachments: Table 1 — Soil Analytical Data <br />Table 2 — Soil Analytical Data — Stockpiled Soil <br />Figure 1 — Site Location Map <br />Figure 2 - Site Plan <br />Attachment A — Field and Laboratory Procedures <br />Attachment B — Certified Laboratory Analytical Reports and Chain -of -Custody <br />Documentation <br />
