4.0 PROPOSED SCOPE OF, <br /> WORK <br /> 4.1 SITE HEALTH AND SAFETY PLAN I <br /> 4.1.1 EnviroSearch will prepare a Site Health ari}d Safety Plan. <br /> 4.2 SITE EXCAVATION <br /> 4.2.1 EnviroSearch will excavate both laterally and vertically until all visual and <br /> i <br /> P.I.D. readings of contamination have been' removed. <br /> i <br /> 4.2.2 Excavate soils will be stockpiled on A/C al�d composite sampled. . <br /> 4.3 CONFORMATION SAMPLING <br /> 43.1= EnviroSearch will collect five (5).discrete c nfirmation samples. One (1) from f <br /> i <br /> bottom of excavation and one (1) from each side wall one foot off bottom of <br /> excavation. i# I <br /> a <br /> 43.2 Samples will be collected in brass tubes from, excavator bucket. Tubes will <br /> ;! E <br /> be sealed with teflon end caps and placed on ice for delivery to F.G.L. <br /> !� E <br /> Laboratories, a state certified lab, under chain-of-custody. t <br /> 4.4 SAMPLE ANALYSIS " <br /> 4.4.1 EnviroSearch will analyze for total petroleumf hydrocarbons .(TVPH as gasoline, <br /> benzene, toluene, xylene, and ethyl benzene} (B.TX&E) 8015, 8020. <br /> 4.5 EXCAVATION BACKFILL <br /> 4.5.1 _ EnviroSearch will back fill excavation with clean imported backfill F <br /> after excavation is determined to be free of contamination" based on <br /> laboratory test results. s <br /> -4.6 STOCKPILED SOIL REMEDIATION 9i <br /> Upon receipt of stockpile soils analysis a remediation plan will be implemented if <br /> results received are an acceptable level. <br /> it <br /> i <br /> ' 1 <br /> I <br /> i <br />
