4 <br /> Sample Analysis <br /> Selected samples will be immediately placed on ice and delivered under chain-of-custody <br /> documentation to a State-certified laboratory for analysis. Soil.samples will be analyzed for total <br /> petroleum hydrocarbons as gasoline (TPHg) and total petroleum hydrocarbons as diesel (TPHd) <br /> using EPA Method 8015 Modified, benzene, toluene, ethylbenzene, and xylenes (BTEX) using <br /> EPA Method 8020, and total lead. Groundwater samples will be analyzed for TPHg, TPHd, <br /> BTEX, oxygenate fuel additives using EPA Method 8260, and total lead. <br /> Report Preparation <br /> Upon completion of all field activities, a summary report will be prepared for submittal to <br /> PHS/EHD. ATC/Smith Technology will prepare a report that will include a description of all <br /> field activities, laboratory analytical results, boring logs, and recommendations. <br /> All work described in this workplan will, be performed under the direction' of a California <br /> Registered Professional Engineer. A completed Site Safety Plan(SSP) is contained in Attachment <br /> 1 and a Quality Control/Quality Assurance Plan is contained in Attachment 2. A11 field work will <br /> be completed in accordance with these plans. <br /> Projected Schedule <br /> Once approval of this workplan has been received, ATC/Smith Technology will schedule drilling <br /> activities. It is anticipated the drilling will be completed in one day and drilling has been J <br /> tentatively scheduled for'December 3, 1997. ATC/Smith Technology will notify PHS/EHD at <br /> least 48 hours prior to beginning any field activities. The summary report will be submitted to <br /> PHS/EHD approximately four to five weeks after the completion of field activities. <br /> w:114980lrepoM4kp.doc 3 <br /> . SIYRH <br />
