kn KLEINFELDER <br />C <br />1 4.1.3 Sample Handlin; <br />After collection, the soil and groundwater samples were labeled, logged on a chain -of -custody, <br />and immediately stored in an iced cooler. The samples were transported under chain -of -custody <br />control to Kleinfelder's office and then transported by courier in a sealed container to Sequoia <br />Analytical of Sacramento, California (Sequoia) for chemical analysis. Sequoia is certified by the <br />California Department of Health Services to perform the requested analyses. The soil and <br />groundwater samples were submitted to Sequoia to perform the proposed analyses on a regular <br />turnaround schedule, usually requiring ten to fourteen working days for completion. <br />4.2 RECYCLING OF DEBRIS <br />The debris excavated from Site 13 was segregated from the soil/lime material. The debris from <br />Site C was also segregated from the soil, but was additionally sifted so the excavated soil could <br />be reused to fill the excavation. The soil and slaked lime excavated from Site B was moved to <br />the lime ponds [all the lime in the lime ponds will be handled in accordance with the Waste <br />Discharge Requirements (WDRs) for the lime ponds]. <br />The debris excavated from these two disposal areas at the site were stockpiled with existing <br />waste construction materials for future recycling. The concrete is to be transported to a <br />temporary onsite crushing plant that will be processing concrete rubble (primarily from the <br />demolished buildings and stora(,e silos) into aggregate that will be used in road construction. <br />Metal will be pulled from the cxcavated debris for later transport to a metals recycling facility. <br />4.3 MONITORING WELL ABANDONMENT <br />4.3.1 Permitting and Pre -Field Activities <br />tKleinfelder submitted a well destruction application for six monitoring wells MW -7 through <br />MW -12 to PHS/EHD on July 8. 1999 for their review. The well destruction application/permit <br />was also obtained on July 8. 1999. For a copy of the well destruction permit please refer to <br />' Appendix C. <br />4.3.1 MonitorinL Well Abandonment <br />Monitoring wells MW -7 through MW -9 were previously installed around the perimeter of Site B <br />and Monitoring wells MW -10 through MW -12 were installed around the perimeter of Site C. The <br />wells were initially installed to monitor groundwater conditions in the vicinity of the two disposal <br />20-3978-03.W36/2019766 Paac I I oi' 20 <br />© 1999. Kleinfeldcr.
