WORK PLAN <br /> FUTURE SAFEWAY STORE, 2782 COUNTRY CLUB BLVD <br /> STOCKTON, CALIFORNIA <br /> Page 2 <br /> Based on our knowledge of soil conditions at the site, a Geoprobe drill rig will be <br /> used to complete the soil and groundwater sampling. Soil samples will be <br /> collected using a piston core sampler equipped with a new acetate sample <br /> sleeve. Each soil sample will be capped, labeled and placed on ice in a <br /> thermally insulated chest pending laboratory analysis. Groundwater samples will <br /> be collected using a new disposable polyethylene bailer. Temporary new PVC <br /> well screen and casing will be inserted into each boring to facilitate the collection <br /> of each groundwater sample. Each groundwater sample will be placed in <br /> containers appropriate for the selected analyses, labeled and placed on ice in a <br /> thermally insulated chest pending laboratory analysis. <br /> Following completion of the sampling activities, each boring will be grouted to the <br /> surface using neat cement. The grout will be allowed to "free fall" down hole, as <br /> the borings will be less than 30 feet in depth. It is anticipated that no waste <br /> materials will be generated during this investigation. <br /> 3.0 LABORATORY ANALYSES <br /> The two soil samples and four groundwater samples will be analyzed for volatile <br /> organic compounds (VOCs), including BTEX compounds and MTBE, using EPA <br /> Method 8260 (low level detection limits) and total petroleum hydrocarbons (TPH) <br /> using EPA Method 8015. The TPH analyses will be preceded by silica gel <br /> cleanup to remove naturally occurring fats or lipids that may cause false positive <br /> results. The samples will be analyzed using a one-week laboratory turnaround <br /> time at CLS Laboratories of Rancho Cordova, California. <br /> 4.0 HEALTH AND SAFETY PLAN <br /> A health and safety plan has been prepared to address safety issues associated <br /> with the proposed drilling at this site, as well as three other Safeway sites where <br /> HIS GeoTrans will be performing similar work in other Counties. A copy of the <br /> safety plan is attached. <br /> 5.0 REPORTING <br /> A brief letter report summarizing the findings of the baseline sampling will be <br /> prepared following completion of the field activities and receipt of the laboratory <br /> analytical data sheets. The report will include a description of the field work, a <br /> comparison of the analytical data to relevant regulatory criteria, and present our <br /> conclusions and recommendations, if any. Tabulated data, a sample location <br /> figure, and the laboratory data sheets will be included. <br />
