Based on a recent telephone conversation between Ms. Nandra <br />Weeks of GeoSyntec and Mr. Al Smith (Chief Compliance Officer, CCC), Ilia <br />recommended analyses for characterization purposes include TCLP for RCRA Inetals, <br />volatile compounds (EPA Method 8260), and serni-volatile compounds (EPA Method <br />8270). GeoSyntec will collect samples (as detailed below) and subttnit the samples to a <br />fixed -base laboratory for analyses in accordance with CCC's requirements to enable <br />Indian River County to characterize the solid drummed waste (i.e., drill cuttings). One <br />sample will be collected from each drum containing drill cuttings. For purposes of the <br />budget estimate, GeoSyntcc has estimated that six drums will be filled with drill <br />cuttings and, thus, will need to be sampled and analyzed for the above-mentioned <br />parameters. The results of the analyses will be used to assess whether or not the <br />waste(s) (i.e., drill cuttings contained in each drum) are hazardous. <br />The analytical results of the monitoring well sampling and analysis will be used to <br />characterize the purge water. from talking to you, GcoSyntec understands that Indian <br />River County has deternnined that purge water collected during sampling of the Gifford <br />Road Landfill monitoring wells is considered to be leachate and, as such, is disposed of <br />in the Indian River County sewer system. GeoSyntec will provide the results of <br />groundwater sampling to Indian River County to assist in Indian River County's waste <br />characterization. <br />Thew drill cuttings and purge drums will be market] as intlicatcd earlier, placed on <br />wood pallets, and stored at an on-site location designated by the SWDD. Any transport <br />and disposal of wastes from the site will be arranged by the SW DD. <br />SCHEDULE <br />In accordance with Figure 5-4 presented in the PRAP, the fieldwork associated <br />with the tasks described above can be initiated within approximately two weeks of <br />receipt of an executed work order. We anticipate that the fieldwork associated with <br />Tasks 2 and 3 will require approximately three weeks to complete. Based on typical <br />three-week laboratory turnaround times and the effort anticipated to evaluate the data <br />XR99170IRO00067.doc <br />F—`l <br />
