FL! <br /> Site Investigation and No Further Action Request ReportT� <br /> R&L Diesel Services, Project#051111 <br /> srRce M4 <br /> 3.0 SCOPE OF WORK <br /> This description of the scope of work documen s the advancement of one soil boring to <br /> p p g <br /> further define the extent of petroleum hydrocarbon impacted soil and groundwater north of the <br /> �+ historical release (Figure 3). <br /> �.t <br /> 3.1 Project Planning and Permitting <br /> WRM obtained the required boring permit(App ndix A) and work plan approval from the <br /> SJCEHD. <br /> Underground Service Alert (USA) was notified a minimum of 48 hours prior to the <br /> installation of the soil borings to locate any utilities int a vicinity of the planned boring location. <br /> As a further precaution against encountering underground utilities during drilling, the upper five <br /> feet of the boring was hand augered. <br /> Prior to initiating fieldwork, a site-specific heaItt and safety plan (HASP) was prepared. <br /> " The HASP included safety procedures for work to be performed, chemical hazard information, <br /> site safety officers, and a medical emergency location. The HASP was kept on site at all times <br /> during the site investigation work. <br /> All work was performed in accordance with COL my regulations, California Code of <br /> Regulations, Title 23, Section 2647 and 2648, and the alifornia Department of Water <br /> _ Resources Bulletins 74-81 and 74-90. Drilling activities were overseen by a California <br /> Professional Geologist. <br /> P 3.2 Soil Boring Advancement <br /> t <br /> 3.2.1 Soil Sampling and Analysis <br /> On April 20, 2009, Taber advanced vertical boring B-5 approximately 7.5 ft. from the <br /> } center of the abandoned UST. During drilling activities undisturbed soil samples were collected <br /> from brass tubes at intervals directed by the SJCEHD. A field geologist continuously logged the <br /> soil samples for hydrogeologic and lithologic characteristics according to the Unified Soil <br /> Classification System and screened each sample for o ganic vapors using a photoionization <br /> detector(PID). The boring log for B-5 is included as A pendix B. <br /> Based on field observations, PID measurement3, and SJCEHD direction, six (6) soil <br /> samples were collected from boring B-5. The soil sam les were sealed with Teflon®sheets and <br /> plastic end caps, labeled, placed in Ziploe sealable begs, packaged in an iced cooler, and <br /> transported with chain-of-custody documentation to Sp rger Technology, Inc. (Sparger) of <br /> Sacramento, California, a state-certified analytical laboratory (ELAP Certification #1614). Each <br /> of the soil samples was analyzed on a standard turn-arDund time for TPH-D and TPH-G by EPA <br /> Method 8015M and for volatile organic compounds, including BTEX and PCE, by EPA Method <br /> FA826013. <br /> k 6 <br />
