Method descriptions are provided below while quality assurance/quality control data is provided in Appendix C. Table 3-l: Source Testing Methodology 3.1 U.S. EPA Reference Test Method 3A - Oxygen/Carbon Dioxide The oxygen (O2) and carbon dioxide (COz) testing was conducted in accordance with U.S. EPA Reference Test Method 3A,. Data was collected online and reported in one-minute averages. The sampling system consisted of a stainless-steel probe, Teflon sample line(s), gas conditioning system and the identified gas analyzer. The gas conditioning system was a non-contact condenser used to remove moisture from the stack gas. If an unheated Teflon sample line was used, then a portable non-contact condenser was placed in the system directly after the probe. Otherwise, a heated Teflon sample line was used. The quality control measures are described in Section 3.6. 3.2 U.S. EPA Reference Test Method 7E - Nitrogen Oxides The nitrogen oxides (NOx) testing was conducted in accordance with U.S. EPA Reference Test Method 7E. Data was collected online and reported in one-minute averages. The sampling system consisted of a stainless-steel probe, Teflon sample line(s), gas conditioning system and the identified gas analyzer. The gas conditioning system was a non-contact condenser used to remove moisture from the stack gas. If an unheated Teflon sample line was used, then a portable non-contact condenser was placed in the system directly after the probe. Otherwise, a heated Teflon sample line was used. The quality control measures are described in Section 3.6. 3.3 U.S. EPA Reference Test Method l0 - Carbon Monoxide The carbon monoxide (CO) testing was conducted in accordance with U.S. EPA Reference Test Method 10. Data was collected online and reported in one-minute averages. The sampling system consisted of a stainless-steel probe, Teflon sample line(s), gas conditioning system, and the identified gas analyzer. The gas conditioning system was a non-contact condenser used to remove moisture fiom the gas. If an unheated Teflon sample line was used, then a portable non-contact condenser was placed in the system directly after the probe. Otherwise, a heated Teflon sample line was used. The quality control measures are described in Section 3.6. 3.4 U.S. EPA Reference Test Method l9 - Volumetric Flow Rate The gas volumetric flow rate was determined in accordance with U.S. EPA Reference Test Method 19 using the measured oxygen concentration, the published fuel factor, a calibrated gas meter and the fuel heating value.

An initial three (3) point calibration was conducted, using individual Protocol I gases, on the analyzer used to complete the dilution system field check. Multiple dilution rates and total gas flow rates were utilized to force the dilution system to perform two dilutions on each mass flow controller. The diluted calibration gases was sent directly to the analyzer, and the analyzer response recorded in an electronic field data sheet. A mid-level supply gas, with a cylinder concentration within l0% of one of the gas divider settings described above, was introduced directly to the analyzer, and the analyzer response recorded in an electronic field data sheet. The cylinder concentration and the analyzer response agreed within 2Yo. These steps were repeated three (3) times. The average analyzer response agreed within 2Yo of the predicted gas concentration. No single injection differed more than 2Yo from the average instrument response for that dilution. Copies of the Method 205 data can be found in the Quality Assurance/Quality Control Appendix. 3.6 Quality Assurance/Quality Control - U.S. EPA Reference Test Methods 3A, l0 and 7E Cylinder calibration gases used met EPA Protocol I (+l- 2%) standards. Copies of all calibration gas certificates can be found in the Quality Assurance/Quality Control Appendix. Low Level gas was introduced directly to the analyzer. After adjusting the analyzer to the Low-Level gas concentration and once the analyzer reading was stable, the analyzer value was recorded. This process was repeated for the High-Level gas. For the Calibration Error Test, Low, Mid, and High-Level calibration gases were sequentially introduced directly to the analyzer. All values were within 2.0 percent of the Calibration Span or 0.5 ppmv absolute difference. High or Mid-Level gas (whichever was closer to the stack gas concentration) was introduced at the probe and the time required for the analyzer reading to reach 95 percent or 0.5 ppm (whichever was less restrictive) of the gas concentration was recorded. The analyzer reading was observed until it reached a stable value, and this value was recorded. Next, Low Level gas was introduced at the probe and the time required for the analyzer reading to decrease to a value within 5.0 percent or 0.5 ppm (whichever was less restrictive) was recorded. If the Low-Level gas was zero gas, the response was 0.5 ppm or 5.0 percent of the upscale gas concentration (whichever was less restrictive). The analyzer reading was observed until it reached a stable value and this value was recorded. The measurement system response time and initial system bias were determined from these data. The System Bias was within 5.0 percent of the Calibration Span or 0.5 ppmv absolute difference. High or Mid-Level gas (whichever was closer to the stack gas concentration) was introduced at the probe. After the analyzer response was stable, the value was recorded. Next, Low Level gas was introduced at the probe, and the analyzer value recorded once it reached a stable response. The System Bias was within 5.0 percent of the Calibration Span or 0.5 ppmv absolute difference or the data was invalidated and the Calibration Error Test and System Bias were repeated. Drift befween pre- and post-run System Bias was within 3% of the Calibration Span or 0.5 ppmv absolute difference. If the drift exceeded 3Yo or 0.5 ppmv, the Calibration Error Test and System Bias were repeated. To determine the number of sampling points, a gas stratification check was conducted prior to initiating testing. The pollutant concentrations were measured at three points (16.7, 50.0 and 83.3 percent of the measurement line). Each haverse point was sampled for a minimum of twice the system response time. AST-2024-4550 RTK - Magna, UT Page 3-2 Aliatpe Source Test Report Testing Methodologlt If the pollutant concentration at each traverse point did not differ more than 5 percent or 0.5 ppmv/0.3% (whichever was less restrictive) of the average pollutant concentration, then single point sampling was conducted during the test runs. If the pollutant concentration did not meet these specifications but differed less than l0 percent or 1.0 ppmvl0.5Yo from the average concentration, then three (3) point sampling was conducted (stacks less than 7.8 feet in diameter - 16.7,50.0 and 83.3 percent of the measurement line; stacks greater than 7.8 feet in diameter - 0.4, 1.0, and 2.0 meters from the stack wall). If the pollutant concentration differed by more than l0 percent or 1.0 ppmvl}.SYo from the average concentration, then sampling was conducted at a minimum of twelve (12) kaverse points. Copies of stratification check data can be found in the Quality Assurance/Quality Control Appendix. An NOz - NO converter check was be performed on the analyzer prior to initiating testing and at the completion of testing. An approximately 50 ppm nitrogen dioxide cylinder gas was introduced directly to the NOx analyzer and the instrument response was recorded in an electronic data sheet. The instrument response was within +i- l0 percent of the cylinder concentration. A Data Acquisition System with battery backup was used to record the instrument response in one (l) minute averages. The data was continuously stored as a *.CSV file in Excel format on the hard drive of a computer. At the completion of testing, the data was also saved to the Alliance server. All data was reviewed by the Field Team Leader before leaving the facility.
