November 2110 <br /> Project No. 1001-0343 <br /> P�asseciatoop RSS G®n` <br /> ® ANVIRONWNTAL RCI6Nf1A7A <br /> 3.5 LABORATORY ANALYTICAL PROGRAM <br /> All collected soil and groundwater samples will be delivered under chain-of-custody <br /> procedures to a State of California-certified laboratory for potential chemical analyses. The <br /> actual soil samples selected for chemical analyses will be based primarily on field observations <br /> (visual, olfactory). The laboratory analytical program includes analyses of selected soil and <br /> groundwater samples for the presence of the following constituents: <br /> • TPH identified as diesel by U.S. EPA method 8015M; <br /> • BTEX by U.S. EPA Method 8260; and <br /> • MTBE by U.S. EPA Method 8260. <br /> 4.0 REPORT PREPARATION <br /> Following receipt and review of the analytical data, Padre will prepare a report <br /> documenting the limited soil and groundwater assessment program. The report will document <br /> the soil and groundwater assessment methodology; site conditions encountered; field <br /> procedures utilized; and will summarize the analytical results. The report will also identify, to <br /> the fullest extent possible, the approximate volume of impacted soil, if encountered. The report <br /> will contain all appropriate figures, and tabular data, and contain our conclusions and <br /> recommendations, as appropriate. The report will be signed and certified by a State of <br /> California-licensed Professional Geologist. <br /> 5.0 SCHEDULE <br /> Padre is proposing to perform the limited soil and groundwater assessment activities <br /> after the existing 8,000-gallon diesel fuel UST has been permanently closed in-place. The <br /> scope of service detailed herein will require approximately four to six weeks to complete. <br /> Permit acquisition will require one to two weeks. The field assessment activities will require one <br /> to two weeks, and chemical analyses of the soil and groundwater samples collected will be <br /> available within one to two weeks. The report will be prepared within two weeks of completing <br /> the fieldwork and receiving the results of the laboratory analyses. <br /> 10.0343.TWP HSP Assessment <br /> - - - 5 - <br />
