CPC CARB 2008 CoMflestlen Tentlog Page S <br /> 4.0 SornpffW and Analyflcal Procedures <br /> 4.1 Emission Test Methods <br /> chis section describes the procedures that TRC followed during the fief kompling program. The test <br /> methods were CARB Methods and EPA Methods. The test methods and procedures used were: <br /> CARB Method I Sampo and Velocity Traverses far Stationary Sources <br /> CARB Method 2 Detemrinatlon of Stack Gas Velocity and Vowmetric Flow state <br /> CARB Method 4 Deterrhinalion of MoMttre Content in Shack Gases <br /> CARB Method 100 Procedures for Continuous Gaseous Ernission Stock 5ompllog <br /> EPA Method 205 Verification of Gas Dilution Systems for Hefts instrument Calibrations <br /> 4.t.1 Gaseous(Combustion)Meastnsments <br /> For the measurement of NOR,CO.VOC,and SO2,pollutants,and the diluents 02 and COs,a transportable <br /> continuous emission monitoring system (TCEMs)was used. The measurement system Is designed to collect <br /> and analyte a dean dry gas sample on a continuous basis. Effluent gas Is extracted from the source <br /> through a stainless steel probe that is connected to a Teftonrm core heated sample One. The gas passes <br /> through this heated system to a conditioner that removes entrained moisture and particulate. The clean <br /> dried gas Is then directed to the measurement system. Periodic purging of the condensate reservoir of the <br /> sample conditioner insures complete water removal and minimal buildup of condensate In the sample <br /> stream. <br /> A gas manifold and metering system is utlted In the measurement systern to direct sample gas to the <br /> analyzw at the proper sample pressure, as dictated by the operating condrtkxu of the monitor. Only a <br /> portion of the conditioned sample gas Is introduced to the colBxated Instrument for analysis while the <br /> remaining sample Is bypassed from the manifold on a continuous basis. <br /> For the VOC component,a heated sample was passed from the extraction point,directly to a heated FID <br /> instrument. This eiirNnates any potential Was or sample loss associated with sample conditioning In <br /> hydrocarbon measurements.
