These levels are within the <br /> range for background lead concentrations and well helow the California Total Thres- <br /> hold Limit Concentration (TTLC) for lead of 1,000 mg/kg. <br /> Remedial Action Goals for Soil <br /> Appendix A is a copy of Table 2-1 from the LUFIF Manual. This worksheet is de- <br /> signed to help determine if soil concentrations of BTEX, TP14-Gas, and TPH-Diesel <br /> can be left in place without threatening groundwater quality. The East Miner location <br /> received a worksheet score of 39 points indicating; that if soil is to be left in place, <br /> BTEX should be nondetectable, TPH-Gas would be less than 10 mglkg, and TPG- <br /> Diesel should be less than 100 mg/kg. These concentration levels were not exceeded in <br /> any of the soil samples collected. The East Miner site soils therefore meet the LUFT <br /> manual criteria and can be left in place. <br /> st'o;iW5sR OW.s1 4-12 <br />
