n a } <br /> iN <br /> Beacon No. 698 - LodE ' <br /> Work Plan <br /> Page No. 12 <br /> 1) Prepare a Site Safety Plan discussing the precautions and protective <br /> equipment required for work at the site. <br /> 2) Acquire all necessary permits from the appropriate regulatory <br /> € agencies to drill and install the three monitoring wells and abandon <br /> the five wells. <br /> 3) drill out monitoring wells MW-1 through MW-5 and grout the hole with <br /> a cement/bentonite slurry. <br /> E 9, <br /> t 4) Drill three 10- to 12-inch diameter soil borings to a maximum depth <br /> of approximately 70 feet each. <br /> 5) Collect and classify relatively undisturbed soil samples from the <br /> borings at 5 foot intervals, or obvious sedimentary contacts, <br /> � . begining at 5 feet below ground surface. An OVM or similar device s <br /> will be used-in the field to subjectively evaluate the potential <br /> concentration of hydrocarbons in the soil samples collected above the <br /> + saturated zone. <br /> 5) Submit an estimated two soil samples per boring for laboratory y <br /> analysis (one sample associated with the highest OVM reading and one i <br /> from directly above the saturated zone) Additional samples may be <br /> ! _ analyzed, as warranted. The samples will be analyzed for the <br /> purgeabie gasoline constituents BTEX, and TPH as gasoline... <br /> 7) Construct one 4-inch-diameter, PVC cased ground-water monitoring well <br /> in each boring and develop th <br /> enew <br /> wells for <br /> sampling. ° <br /> 8) Collect ground-water samples from the monitoring wells and submit the <br /> samples for laboratory analysis for BTEX and TPH. <br /> 9) Survey the wells using a land surveyor and evaluate the ground-water <br /> { gradient and flow direction: <br /> 10) Prepare a technical report summarizing field and laboratory <br /> procedures,.findings, interpretations, conclusions, and ` <br /> recommendations. <br /> S-iteSafety Plan <br /> Field work performed by Dltramar's consultant at the site will be <br /> conducted.in accordance with a Site Safety Plan.
