Following sampling , each of the soil borings will be abandoned using neat cement grout. The <br /> boreholes will be filled with grout from the bottom using a tremie pipe. Following borehole <br /> abandonment, the surface pavement will be restored . <br /> Soil and groundwater samples will be properly contained , labeled , preserved and transported <br /> under chain-of-custody documentation to a state of California certified hazardous waste testing <br /> laboratory for analysis. The soil samples from the capillary fringe interval and from the bottom of <br /> the borehole from each boring will be submitted for laboratory analysis. Based on field <br /> observations and PID measurements, additional soil samples may be submitted for analysis, if <br /> required to adequately characterize the site. Field observations and sample selection will be <br /> reviewed with the EHD inspector, prior to sample submittal to the lab . <br /> The lab will analyze each of the soil samples on a standard turn-around time for TPH-as- <br /> - kerosene, TPH-as-gasoline, and BTEX by EPA Method 8020/8015M . Since concentrations of <br /> TPH-as-motor oil , TPH-as-diesel , oxygenates and 1 , 2-DCA were defined during previous <br /> investigations , further testing for these compounds in soil will be discontinued . <br /> Ii <br /> ` The lab will analyze each groundwater sample on a standard turn-around time for TPH�as- <br /> kerosene, TPH-as-gasoline and BTEX by EPA Method 8020/8015M , and for MTBE , DIPE , <br /> ETBE, TAME , TBA, and 1 , 2-DCA by EPA Method 8260B . Since concentrations of TPH-as- <br /> motor oil and TPH-as-diesel have not been detected during the past four quarters of <br /> groundwater sampling at the site, further testing for these compounds in groundwater will be <br /> - discontinued . <br /> 3.3 Project Report <br /> Ramage Environmental will document the results of the proposed scope of work in an <br /> environmental site investigation report, according to Appendix A of the Tri-Regional <br /> Recommendations for Preliminary Investigation and Evaluation of Underground Storage Tank <br /> Sites. All reports will be prepared and stamped by a state of California Registered Geologist and <br /> submitted to EHD and RWQCB . <br /> I <br /> I ' <br /> 10 <br />
