Project No. 034-17016 <br /> Site-Specific Health& Safety Plan <br /> Page No. 9 <br /> 16. Following completion of the field and laboratory investigation activities,we will prepare a report. <br /> The report will summarize the investigation methodology and will present the results of the chemical <br /> analysis of the soil,groundwater and soil vapor samples. If contaminants are encountered,we will <br /> identify the contaminants and will include a comparison of the contaminant levels to State or Federal <br /> regulatory screening levels. In addition to presenting our findings,the report will also include our <br /> conclusions and recommendations, based on the results of the laboratory analyses, that we deem <br /> prudent for further assessment, if warranted. The laboratory analytical reports for the soil, <br /> groundwater and soil vapor sample analyses will be appended to the report. Final copies of the report <br /> will include an electronic copy(PDF)and up to two(2)bound copies,if requested,sent to the client. <br /> InvestiEation of Client-Directed AOCs <br /> 1. ON-SITE FUELING SYSTEWUSTS/DISPENSERS — USTS, FUEL DISPENSERS AND <br /> PRODUCT LINES <br /> 20,000-GALLON DIESEL USTs <br /> • Four (4) soil borings will be completed to a depth of 20 to 30 feet bgs (depending on depth to <br /> groundwater),one(1)boring at each end of the location of the two(2)20,000-gallon USTs reported <br /> to be currently occupying the subject site. <br /> • Soil samples will be collected beginning at five (5) feet bgs and at five (5) foot intervals to the <br /> maximum depth of the borings.A total of 24 soil samples will be collected from the USTs area and <br /> field screened with the PID. <br /> • Based upon the results of field screening,the two(2)soil samples from each boring demonstrating <br /> the highest potential for contamination will be submitted to the laboratory for analysis.If no samples <br /> from a boring demonstrate the potential for contamination,the samples from 15 and 25 feet bgs from <br /> that boring will be submitted for analysis. If groundwater is encountered,the deeper sample will be <br /> collected as close as practical to the capillary fringe. The remaining samples will be kept on hold at <br /> the laboratory. <br /> • A total of eight (8)soil samples from the USTs area will be submitted for analysis of TPH-d and <br /> VOCs. <br /> • Two(2)grab groundwater samples will be collected from two(2)of the soil borings completed near <br /> the USTs. The groundwater samples will be analyzed for TPH-d and VOCs. <br /> • One(1)soil vapor boring will be completed to a depth of 5.5 feet bgs near the USTs and one(1)soil <br /> vapor sample will be collected and analyzed for VOCs. <br /> 550-GALLON NEW OIL UST <br /> • One(1)soil boring will be completed to a depth of approximately 12 feet bgs near the 550-gallon <br /> new oil UST. <br /> • Soil samples will be collected at eight(8)and 12 feet bgs. <br /> • The two(2)soil samples will be analyzed for TPH-cc. <br /> 550-GALLON WASTE OIL UST <br /> • One(1) soil boring will be completed to a depth of approximately 12 feet bgs near the 550-gallon <br /> waste oil UST. <br /> • Soil samples will be collected at eight(8)and 12 feet bgs. <br /> • The two(2)soil samples will be analyzed for TPH-cc,VOCs,CAM 17 metals and PCBs. <br /> KRAZAN&ASSOCIATES,INC. <br /> With Offices Serving the Western United States <br /> 03417016 SSI Lathmp HASP Final.doc <br />
