APT Project CMX2453 Test Report, Kiln Stack Emissions (March 24, 2003} using a K-type thermocouple and an S-type pitot tube. Prior to sampling, the sorbent trap was cleaned, packed with XAD-2 resin, and spiked with isotopically labeled PCDD and PCDF congeners by Philip Analytical personnel. The first two impingers each contained 100 mil{iliters of high performance liquid chromatography (HPLG) grade water. The third impinger was empty. The fourth impinger contained approximately 250 grams of dried silica gel. Following each sampling period, the probe filter, the sorbent trap, and a series of solvent rinses (acetone, toluene and methylene chloride in separate containers in accordance with Philip Analytical recommended procedures) of the probe, Houle, and condenser, and the impinger contents were recovered for subsequent GC/MS analysis for the Method 23 PCDD and PCDF target analytes, Method 428 PCB target analytes, and the Method 429 PAH target analytes . The various sample fractions were composited, as applicable, with no analysis or reporting of results for separate sample fractions. The laboratory data were combined with field data to calculate the PCDD/PCDF emissions in units of toxic equivalent emission concentration (nanograms per dry standard cubic meter}, corrected to 7% OZ (TEQ ng/dscm @ 7% OZ). PCB laboratory results were all reported as non-detected (please see Appendix 3 -Laboratory Data). PAH results were calculated in units of Ib(hr. As these runs were conducted simultaneously with the EPA Method 29 sample runs, the diluent (oxygen and carbon dioxide) data remain the same. 5.2.1. Suaolemental QAlQC Procedures - PCDDslPCDFs, PCBs and PAHs As required by the method, the sorbent spike recoveries were determined for all isotopically labeled congeners, and the D6225 2,3,7,8-TCDF quantification column procedures will be used. Proper caution was exercised in both field sampling and sample handling to minimize the risks of contamination and/or spike foss. Additionally, a true sample train blank was collected and analyzed concurrent with the emission samples. Field blank collection procedures were identical to those detailed in Section 5.1.1 for PM /Metals. Additionally, a reagent blank (acetone, methylene chloride, toluene, and quartz fiber filter) was archived for possible analysis pending review of the laboratory data. 5.3. Hvdrooen Chloride (HCI HCI emissions were determined in accordance wfth EPA Method 26A. PM emissions were also determined using the particulate catch from the EPA Method 26A sampling train as a double check on the EPA Method 29 PM results. page 16
