LLNL-TR-720159 <br />Attachment 103 a, b, c <br />a) The non -hazardous waste determination of the granulated activated carbon (GAC) was <br />made by generator and process knowledge based on the area in which the GAC was used <br />at Site 300. After inquiry from SJCEHD, the non -hazardous determination was verified by <br />volatile organic compound and fish toxicity analyses. The complete analytical data <br />packages are provided in this attachment. <br />b) The transformers located outside of B-872 were sampled and analyzed and were <br />determined not to contain any PCBs and the oil is being managed as CA hazardous waste. <br />The complete analytical data packages are provided in this attachment. <br />c) The sludge from the oil water separator at B-879 was analyzed for metals content. Upon <br />review of the data, it was determined that the lead concentration (57.8 mg/kg) was above <br />the 10x rule for CA STLC hazardous waste determination, but below the 20x rule for <br />federal TCLP hazardous waste determination. Therefore, rather than running the waste <br />for the STLC, LLNL will conservatively manage this as CA hazardous waste. <br />PPCEIVED <br />FEB 0 9 2017 <br />ENVIRONMENTAL HEALTH <br />DEPARTMENT <br />Prepared by LLNL under Contract DE-AC52-07NA27344. <br />
