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 Methods I and 2 - Sampling/Traverse Points and Volumetric Flow Rate The sampling location and number of traverse (sampling) points were selected in accordance with U.S. EPA Reference Test Method l. To determine the minimum number of traverse points, the upstream and downsffeam distances were equated into equivalent diameters and compared to Figure I -2 in U.S. EPA Reference Test Method I . Full velocity traverses were conducted in accordance with U.S. EPA Reference Test Method 2 to determine the average stack gas velocity pressure, static pressure and temperature. The velocity and static pressure measurement system consisted of a pitot tube and inclined manometer. The stack gas temperature was measured with a K-type thermocouple and pyrometer. Stack gas velocity pressure and temperature readings were recorded before and after each test run. The data collected before and after each test run was averaged. The averages were utilized to calculate the volumetric flow rate in accordance with U.S. EPA Reference Test Method 2. Stack gas velocity pressure and temperature readings were recorded during each test run. The data collected was utilized to calculate the volumetric flow rate for comparison to the continuous emission rate monitoring system (CERMS). The relative accuracy of the CERMS was determined based on procedures found in 40 CFR 60, Performance Specifi cation 6. 3.2 U.S. EPA Reference Test Method 3A - Oxygen/Carbon Dioxide The oxygen (Oz) 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 3.7. AST-2024-2322-001 RTK * Magna, UT Page 3-l AI ir i.l l(Source Test Report Tesling Methodologt 3.3 U.S. EPA Reference Test Method 4 - Moisture Content The stack gas moisture content (BWS) was determined in accordance with U.S. EPA Reference Test Method 4. The gas conditioning train consisted of a series of chilled impingers. Prior to testing, each impinger was filled with a known quantiry of water or silica gel. Each impinger was analyzed gravimetrically before and after each test run on the same balance to determine the amount of moisture condensed. 3.4 U.S. EPA Reference Test Method 6C - Sulfur Dioxide The sulfur dioxide (SOz) testing was conducted in accordance with U.S. EPA Reference Test Method 6C. Data was collected online and reported in one-minute averages. The sampling system consisted of a heated stainless steel probe, Teflon sample line(s), gas conditioning system and the identified analyzer. The gas conditioning system was a non-contact condenser used to remove moisfure from the source 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 3.7. The relative accuracy of the SOz CEMS was determined based on procedures found in 40 CFR 60, Performance Specification 2. 3.5 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 lE. Data was collected online and repofted 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 3.7. The relative accuracy of the NOx CEMS was determined based on procedures found in 40 CFR 60, Performance Specification 2. 3.6 U.S. EPA Reference Test Method 205 - Gas Dilution System Certification A calibration gas dilution system field check was conducted in accordance with U.S. EPA Reference Method 205. 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 were sent directly to the analyzer, and the analyzer response recorded in an electronic field data sheet. The analyzer response agreed within 2% of the actual diluted gas concentration. A second Protocol I calibration gas, with a cylinder concentration within l0% of one of the gas divider settings described above, was inffoduced directly to the analyzer, and the analyzer response recorded in an electronic field data sheet. The cylinder concentration and the analyzer response agreed within 2o/o. These steps were repeated three (3) times. Copies of the Method 205 data can be found in the Quality Assurance/Quality Control Appendix. 3.7 Quality Assurance/Quality Control - U.S. EPA Reference Test Methods 3A, 6C 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 FtalEe (r; ilrI , r' AST-2024-2322-001 RTK - Magna, UT Page 3-2 Source Tesl Report Testing Methodologt 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 lo/o absolute difference. High or Mid-Level gas (whichever was closer to the stack gas concentration) was infroduced at the probe and the time required for the analyzer reading to reach 95 percent or 0.5 ppmv/% (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 ppmv/% (whichever was less restrictive) was recorded. If the Low- Level gas was zero gas, the response was 0.5 ppmvlo/o 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 analyzet 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 ppmvloh absolute difference or the data was invalidated and the Calibration Error Test and System Bias were repeated. Drift between pre- and post-run System Bias was within 3 percent of the Calibration Span or 0.5 ppmv/7o absolute difference. If the drift exceeded 3 percent or 0.5 ppmv/%, the Calibration Enor 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 traverse point was sampled for a minimum of twice the system response time. 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. Ifthe pollutant concentration did not meet these specifications but differed less than l0 percent or 1.0 ppmvl0.5%o 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 fiom the stack wall). If the pollutant concentration differed by more than l0 percent or 1.0 ppmv/0.5% from the average concentration, then sampling was conducted at a minimum of twelve (12) traverse points. Copies of stratification check data can be found in the Quality Assurance/Quality Control Appendix. An NOz - NO converter check was performed on the analyzer prior to initiating testing. An approximately 50 ppm n itrogen 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 +/- 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. Once arriving at Alliance's office, all written and electronic data was relinquished to the report coordinator and then a final review was performed by the Project Manager.

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 Methods I and 2 - Sampling/Traverse Points and Volumetric Flow Rate The sampling location and number of traverse (sampling) points were selected in accordance with U.S. EPA Reference Test Method L To determine the minimum number of traverse points, the upstream and downstream distances were equated into equivalent diameters and compared to Figure I -2 in U.S. IIPA Reference Test Method I . Full velocity traverses were conducted in accordance with U.S. EPA Reference Test Method 2 to determine the average stack gas velocity pressure, static pressure and temperature. The velocity and static pressure measurement system consisted of a pitot tube and inclined manometer. The stack gas temperature was measured with a K{ype thermocouple and pyronreter. Stack gas velocity pressure and temperature readings were recorded during each test run. 'lhe data collected was utilized to calculate the volumetric flow rate in accordance with U.S. EPA Reference Test Method 2. 3.2 U.S. EPA Reference Test Method 3/3A - Oxygen/Carbon Dioxide The oxygen (O:) and carbon dioxide (COz) testing was conducted in accordance with U.S. EPA Reference Test Method 3/3A. One (l) integrated Tedlar bag sample was collected during each test run. 'fhe bag samples were analyzed on site with a gas analyzer. The remaining stack gas constituent was assumed to be nitrogen for the stack gas molecular weight determination. The quality control measures are described in Section 3.6. 3.3 U.S. EPA Reference Test Method 4 - Moisture Content l'he stack gas rnoisture content (BWS) was determined in accordance with U.S. EPA Reference Test Method 4. I'he gas conditioning train consisted of a series of chilled impingers. Prior to testing, each impinger was filled with a known quantity of water or silica gel. IJach impinger was analyzed gravintetrically before and after each test run on the sarne balance to deterrnine the anrount of moisture condensed. 3.4 U.S. EPA Reference Test Method 6C - Sulfur Dioxide I'he sullur dioxide (SO2) testing was conducted in accordance with U.S. EPA Reference Test Method 6C. Data was collected online and reported in one-minute averages. The sampling systern consisted of a heated stainless steel probe, T'eflon sarnple line(s), gas conditioning systern and the identified analyzer. 1-he gas conditioning system was a non-contact condenser used to remove moisture from the source gas. If an unheated J'eflon sanrple line was used, AS',I -2024-2322-002 I{1 K Magna. Ll l' rla i l'.,,'t AI lEe {i I Source Tesl Report Tesling Methodolop, 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 3.7. The relative accuracy of the SOz CEMS was determined based on procedures found in 40 CFR 60, Performance Specification 2. 3.5 U.S. EPA Reference Test Method 205 - Gas Dilution System Certification A calibration gas dilution system field check was conducted in accordance with U.S. EPA Reference Method 205. 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 within2Yo of the predicted gas concentration. No single injection differed more than 2%ofrom 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 Method 3/3A 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 0.5o/o absolute difference. 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. Once arriving at Alliance's office, all written and electronic data was relinquished to the report coordinator and then a final review was performed by the Project Manager. 3.7 Quality Assurance/Quality Control - U.S. EPA Reference Test Method 6C Cyf inder calibration gases used met EPA Protocol | (+l- 2%) standards.

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 ppmv/% (whichever was less restrictive) was recorded. If the Low- Level gas was zero gas, the response was 0.5 ppmvlo/o 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 fi'om 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 ppmvlo/o absolute difference or the data was invalidated and the Calibration Error Test and System Bias were repeated. Drift between pre- and post-run System Bias was within 3 percent of the Calibration Span or 0.5 ppmv/7o absolute difference. If the drift exceeded 3 percent 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 traverse point was sampled for a minimum of twice the system response time. If the pollutant concentration at each traverse point did not differ more than 5 percent or 0.5 ppmv/O.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 ppmvl}.5%o 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}.5Yo from the average concentration, then sampling was conducted at a minimum of twelve (12) traverse points. Copies of stratification check data can be found in the Quality Assurance/Quality Control Appendix. 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. Once arriving at Alliance's office, all written and electronic data was relinquished to the report coordinator and then a final review was performed by the Project Manager.
