Samples will 69 be analyzed for BTEX, TPHg, and MTBE using EPA methods 802018015; and for total lead using EPA method 200.8. If MTBE is detected in a sample using EPA method 8020, that sample will be run for oxygenates utilizing EPA method 8260. 3.3 TECHNICAL REPORT Upon completion of the field investigation and laboratory testing, a Site Investigation and V Evaluation report will be prepared summarizing results and findings, following Tri-Regional Board Staff Recommendations (Central Valley Regional Water Quality Control Board, 1991). The data obtained during this investigation will be evaluated along with the historical data collected from the site to evaluate the lateral and vertical extent of PHCs beneath the site. Based on these findings, appropriate actions will be recommended. This report will also include a figure depicting the site location and existing features, a geologic cross section depicting PHC-impacted areas and the depth to groundwater, tabulated analytical results, and copies of all permits obtained for the work. V 3.4 HEALTH AND SAFETY B&R Health and Safety plan for the subsurface investigation is provided in Appendix E. A copy of this plan will be available on-site during the field work.
