t <br /> encountered, one grab groundwater sample will be collected at each boring location <br /> (total of four groundwater samples) and submitted for laboratory analyses. If <br /> groundwater is not encountered within 30 feet of ground surface, then one soil sample <br /> from each boring location will be submitted for laboratory analysis. Each sample will be <br /> analyzed for volatile organic compounds (VOCs), including BTEX compounds and <br /> MTBE, using EPA Method 8260 (low level detection limits) and total petroleum <br /> hydrocarbons (TPH) using EPA Method 8015. The TPH analyses (for the diesel fuel <br /> and oil range hydrocarbons) will be preceded by silica gel cleanup to remove naturally <br /> occurring fats or lipids that may cause false positive results. The samples will be <br /> analyzed using a one-week laboratory turn around time. The push rods will be pulled <br /> and the 1.5 inch diameter borings will be cement-grouted to surface. <br /> HEALTH AND SAFETY PLAN <br /> A site-specific Health and Safety Plan (HASP) will be prepared prior to fieldwork. The <br /> HASP will address the scope of work and safety concerns for the Property. An <br /> underground utility clearance will also be performed before the drilling is conducted. <br /> SCHEDULE <br /> The fieldwork will begin as soon as soil boring permit is received from San Joaquin County. <br /> The actual drilling should be completed in one field day, provided sufficient groundwater <br /> enters the boririgs to allow for sampling. The schedule is broken down as follows: <br /> Week 1 Prepare HASP,work plan, submit soil boring permit application. <br /> Week 2 San Joaquin County Department of Environmental Health <br /> reviews the permit application. <br /> Week 3 Perform the fieldwork, including utility clearance and drilling. <br /> Week 4 and 5 Receive laboratory data and prepare the written report. <br /> The laboratory analytical data will be available approximately one week following the <br /> fieldwork. A verbal status report will be provided after the fieldwork is completed and <br /> GeoTrans has received the analytical data. <br /> 2 <br />
