AFAE <br /> 4WU -. <br /> Should the Division not approve the CKD using activated carbon and hydrated lime, CEMEX <br /> will remove the material from C-Pit and landfill in an appropriate method. The material will <br /> be stored in a manner as to distinguish itself from the capping material and existing C-Pit <br /> storage. <br /> Enclosed is Attachment 1 which is a schematic of Waste Dust(CKD)from baghouse to C-Pit. <br /> The process of CKD handling and processing would not change with the addition of lime and <br /> carbon <br /> The Kiln dust sampling plan will consist of the following parameters: <br /> • A baseline kiln baghouse sample shall be obtained with no lime or carbon injection. <br /> This will consist of 1 composite sample under normal operating conditions. The <br /> sample will consist of 4 individual samples over a 30 minute period which will mixed <br /> into 1 composite sample. The sample point will be the exit end of the baghouse prior <br /> to dust silo. <br /> The sample will be analyzed for TCLP Metals (EPA Method 1311),Total Metals as listed in <br /> Table 1 of the CDPHE,Water Quality Control Commission 5 C.C.R. 1002-41, Regulation 41 - <br /> The Basic Standards for Groundwater(analytes omitted from analysis include; asbestos, <br /> cyanide, nitrite, nitrate, and total nitrite and nitrate). In-addition, Paste pH test will be <br /> conducted. <br /> • Activated Carbon/Lime Injection-A composite sample shall be gathered while <br /> injecting activated carbon and hydrated lime. The composite sample will consist of <br /> one sample every 15 minutes for a total of 4 samples. The injection rate used for <br /> testing will be 12 Ib/hr activated carbon and hydrated lime application rate of 200 <br /> Ibs/hr. Note typical injection rates are expected to be less than the maximum <br /> projected. <br /> The sample will be analyzed for TCLP Metals(EPA Method 1311),Total Metals as listed in <br /> Table 1 of the CDPHE,Water Quality Control Commission 5 C.C.R. 1002-41, Regulation 41 - <br /> The Basic Standards for Groundwater(analytes omitted from analysis include; asbestos, <br /> cyanide, nitrite, nitrate, and total nitrite and nitrate). In-addition, Paste pH test will be <br /> conducted. The sample point will be the exit end of the baghouse prior to dust silo. <br /> 2 of 3 <br />
