However, depending on <br /> the size and condition of the finished excavation, additional soil samples may need to be obtained <br /> above what is proposed in the workplan. Please be prepared to collect additional samples, if needed. <br /> Should the over-excavation fail to remove all impacted soil and groundwater, fate and transport <br /> modelling may be needed to indicate future environmental impact. Therefore, the soil samples being <br /> collected may also be analyzed for several model input parameters, such as organic carbon content, <br /> porosity, hydraulic conductivity, etc, if needed. <br /> The workplan does not address the ultimate fate of the soil to be generated by over-excavation. <br /> Therefore, a soil treatment and/or disposal plan should be submitted at the same time as the report of <br /> findings. <br /> The work as proposed in the workplan can be scheduled to begin at any time. Please provide <br /> PHSIEHD with at least 48 hours advance notice prior to beginning site work. <br /> If you have any questions or wish to discuss this letter in more detail, please contact Linda Turkatte, <br /> Senior REHS, at (209) 468-3441. <br /> Donna Heran, REHS, Director <br /> Environmental Health M&Twj� <br /> Linda Turkatte, Senior REHS Diane M.
