' offsite receptors Direct exposure to hydrocarbons in soils beneath the site was also evaluated <br /> for both daily site workers and potential future construction workers <br /> The results of the RSCA analysis indicate (1) The risk associated with commercial/industrial <br /> exposure to detected levels of hydrocarbons in surface soils is protective of target levels adopted <br />' by the USEPA, (2) the risk associated with commercial/industrial and residential exposure to <br /> detected levels of hydrocarbons and MTBE in soil vapor beneath the site is protective of target <br /> risk levels adopted by the USEPA, (3) the construction worker exposure risk associated with a <br />' single historical benzene concentration in a soil sample exceeds the USEPA-defined target risk <br /> range, and therefore an appropriate health and safety plan should be developed, ensuring <br /> protection of future construction workers at the site <br /> Based on 1 the historical and existing concentrations of petroleum hydrocarbons in soil <br /> ( ) g p Y <br /> groundwater, and vapor phase, (2) the remedial efforts implemented at the site, and (3) the <br /> results of the RBCA analysis, ETIC recommends no further remedial action at the site A <br /> proposed reduced groundwater sampling schedule and the associated destruction of extraneous <br /> wells is presented in Table S Figure 10 presents graphically which wells will be kept as part of <br /> the monitoring program and which wells are proposed for destruction <br /> 1 <br /> G TIowLt5173942VMAS rFRNWPkRaO8C I ttexC Joc 13 <br />
