(d) The United States Geological Survey (USGS ) or county map showing the <br /> location of the remediation waste management site is depicted by Figure 1 in the <br /> " Application for RAP Order for Soil Treatment Cell Operation , " January 16 , 2004 . <br /> (e) The following figures in the "Application for RAP Order for Soil Treatment Cell <br /> Operation, " January 16 , 2004 , describe the remediation areas and layout of the <br /> remediation equipment . Figure 2 is an aerial photograph of the South Gifford Road <br /> Landfill area. Figure 3 shows the approximate limits of the proposed excavation <br /> area and soil stockpile locations . Figure 4 is a schematic of the soil treatment <br /> process . <br /> (f) The remediation waste to be treated or stored at the remediation waste <br /> management site consists of soil contaminated by various chlorinated volatile <br /> organic constituents , such as , trichloroethene (TCE) , cis- 1 ,2-dichloroethene (cis- <br /> DCE) , and vinyl chloride . <br /> (g) The estimated amount of soil to be excavated is 6 ,400 cubic yards ; approximately <br /> 1 ,700 cubic yards may require treatment. The actual volume requiring treatment will <br /> be based upon field soil sampling results . <br /> (h) In the event that soil vapor extraction does not reduce the contamination below <br /> the toxicity characteristic leaching procedure (TCLP) criteria and Land Disposal <br /> Restriction (LDR) standards within 90 days , the soil will be disposed at a permitted <br /> hazardous waste disposal site. <br /> (i) The following specific conditions will also apply to the operation of the soil <br /> treatment cells and staging piles identified in the Work Plan : <br /> ( 1 ) The County will maintain a record of the date waste is first placed in each <br /> treatment cell ; and <br /> (2) The County will have a 10 mil reinforced low density polyethylene liner <br /> between the ground surface and any treatment cell containing fill <br /> material , impacted soil , or sediment that exhibits a characteristic of <br /> hazardous waste due to concentrations above the TCLP regulatory <br /> threshold ; and, <br /> (3 ) The County must use a 10 mil reinforced low density polyethylene liner <br /> to cover each treatment cell ; and <br /> (4) Each treatment cell must not be used longer than 90 days ; and <br /> Page 4 <br />
