a <br /> The project RI entitled Remedial Investigation Report, North Shore Parcels, Stockton, California <br /> (Treadwell &Rollo, 2000a), and the FS entitled Feasibility Study, North Shore Parcels, <br /> Stockton, California (Treadwell & Rollo, 2000b)-were completed in 2000. Two FS addendums <br /> were then completed in response to DTSCcomments (Treadwell & Rollo, 2000c and 2001a). <br /> The amended FS selected.the following remedial action objectives (RAOs) for soil and <br /> groundwater. <br /> r <br /> i <br /> Remedial Action Objectives <br /> s <br /> 4 x ...

The excavations around <br /> hot spot samples will be referred to as RAP excavations. <br /> k <br /> The selected remedial method included conducting RAP excavations at all hot spot sample <br /> locations. At RAP excavations, the initial excavation proposed was six feet long by six feet wide <br /> v <br /> 25971025.DGD 8 11 August 2005 <br />
