For excavated soils, the property owner should ensure that <br /> potentially-Affected Soil is stockpiled in a separate location from non-Affected Soil to <br /> allow for proper profiling and management. <br /> A construction/utility worker direct contact RBC of 12,563 mg/kg for TPHc was <br /> established by the HHRA presented in CRA's May 13, 2013 Subsurface Investigation <br /> Report and Updated Site Conceptual Model'. Soil samples collected by SHELL's <br /> representative will be analyzed for TPHc by EPA Method 8015M. The soil sample <br /> analytical result(s) will be used to assess and support mitigation of construction/utility <br /> worker exposure. <br /> The soil sample analytical result(s) will also be used to determine if Affected Soil is <br /> adequate for re-use (a geotechnical evaluation would be conducted by others) or <br /> requires off-site disposal. Soil sample analytical result(s) less than the TPHc RBC of <br /> 12,563 mg/kg will be the criteria for determining Affected Soil re-use suitability. If the <br /> Affected Soil is not suitable for re-use, based on soil sample analytical result(s) greater <br /> than the TPHc RBC of 12,563 mg/kg, then SHELL will arrange for the removal, <br /> transportation,and off-site disposal of the Affected Soil by a qualified waste contractor. <br /> 1 http://geotracker.waterboards.ca.gov/profile_report.asp?global_id=SL0607708243 <br /> 060223(33) 5 CONESTOGA-ROVERS&ASSOCIATES <br />
