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 2.8. 2.5 U.S. EPA Reference Test Method 10 – 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 from 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 2.8. 2.6 U.S. EPA Alternative Test Method ALT-096 – Non Methane Hydrocarbons The non-methane hydrocarbon (NMHC) testing was conducted in accordance with U.S. EPA Alternate Test Method ALT-096. EPA Method 25A is incorporated by reference. The sampling system consisted of a stainless steel probe, heated Teflon sample line(s) and the Thermo 55i analyzer. The quality control measures are described in Section 2.9. 2.7 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 1 calibration gas, with a cylinder concentration within 10% 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 2%. These steps were repeated three (3) times. Copies of the Method 205 data can be found in the Quality Assurance/Quality Control Appendix. 2.8 Quality Assurance/Quality Control – U.S. EPA Reference Methods 3A, 7E and 10 Cylinder calibration gases used met EPA Protocol 1 (+/- 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 Mid Level gas. Next, High Level gas was introduced directly to the analyzer, and the response recorded when it was stable. 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 9 of 63 Source Test Report Testing Methodology AST-2023-4493 Nodal Power – Layton, UT Page 2-3 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 between pre- and post-run System Bias was within 0.5 ppmv absolute difference or 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% or 0.5 ppm (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 10% or 1.0 ppm 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 10% or 1.0 ppm 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 NO2 – NO converter check was performed on the analyzer prior to initiating 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 +/- 10 percent of the cylinder concentration. A Data Acquisition System (Dutech Analog Signal Modules) with battery backup was used to record the instrument response in one (1) 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. 2.9 Quality Assurance/Quality Control – U.S. EPA Reference Method ALT-096 EPA Protocol 1 Calibration Gases – Cylinder calibration gases used met EPA Protocol 1 (+/- 2%) standards. Copies of all calibration gas certificates are provided in the Quality Assurance/Quality Control Appendix. 10 of 63 Source Test Report Testing Methodology AST-2023-4493 Nodal Power – Layton, UT Page 2-4 Zero gas was introduced through the sampling system to the analyzer. After adjusting the analyzer to the Zero gas concentration and once the analyzer reading was stable, the analyzer value was recorded. This process was repeated for the High Level gas, and the time required for the analyzer reading to reach 95 percent of the gas concentration was recorded to determine the response time. Next, Mid and Low Level gases were introduced through the sampling system to the analyzer, and the response was recorded when it is stable. All values must be within +/- 5% of the calibration gas concentrations. Post Test Drift Checks – Mid Level gas were introduced through the sampling system. After the analyzer response was stable, the value was recorded. Next, Zero gas was introduced through the sampling system, and the analyzer value recorded once it reached a stable response. The Analyzer Drift must be less than 3 percent of the Calibration Span. Data Collection – A Data Acquisition System with battery backup was used to record the instrument response (analog 0-10 volt signal) in one (1) minute averages. The data was continuously stored as a *.CSV file in Excel format on the hard drive of a desktop computer. At the completion of the emissions testing the data was also saved to disk. 11 of 63 Appendix A 12 of 63 Appendix A Example Calculations Location Source Project No. Run No. Parameter(s) Meter Pressure (Pm), in.

The gas conditioning train will consist of a series of chilled impingers. Prior to testing, each impinger will be filled with a known quantity of water or silica gel. Each impinger will be analyzed gravimetrically before and after each test run on the same analytical balance to determine the amount of moisture condensed. 3.4 U.S. EPA Reference Test Method 7E – Nitrogen Oxides The nitrogen oxides (NOx) testing will be conducted in accordance with U.S. EPA Reference Test Method 7E. Data will be collected online and reported in one-minute averages. The sampling system will consist of a stainless steel probe, Teflon sample line(s), gas conditioning system and the identified gas analyzer. The gas conditioning system will be a non-contact condenser used to remove moisture from the stack gas. If an unheated Teflon sample line is used, then a portable non-contact condenser will be placed in the system directly after the probe. Otherwise, a heated Teflon sample line will be used. The quality control measures are described in Section 3.9. 3.5 U.S. EPA Reference Test Method 10 – Carbon Monoxide The carbon monoxide (CO) testing will be conducted in accordance with U.S. EPA Reference Test Method 10. Data will be collected online and reported in one-minute averages. The sampling system will consist of a stainless steel probe, Teflon sample line(s), gas conditioning system, and the identified gas analyzer. The gas conditioning system will be a non-contact condenser used to remove moisture from the gas. If an unheated Teflon sample line is used, then a portable non-contact condenser will be placed in the system directly after the probe. Otherwise, a heated Teflon sample line will be used. The quality control measures are described in Section 3.9. 3.6 U.S. EPA Reference Test Method 25A – Volatile Organic Compounds The volatile organic compounds (VOC) testing will be conducted in accordance with U.S. EPA Reference Test Method 25A. Data will be collected online and reported in one-minute averages. The sampling system will consist of a stainless steel probe, heated Teflon sample line(s) and the identified gas analyzer. The quality control measures are described in Section 3.10. 3.7 U.S. EPA Alternative Test Method ALT-096 – Volatile Organic Compounds The volatile organic compounds (VOC) testing will be conducted in accordance with U.S. EPA Alternate Test Method ALT-096. EPA Method 25A is incorporated by reference. The sampling system will consist of a stainless steel probe, heated Teflon sample line(s) and a Thermo 55i analyzer. VOC data will be collected in one (1) minute averages. The quality control measures are described in Section 3.11. 3.8 U.S. EPA Reference Test Method 205 – Gas Dilution System Certification A calibration gas dilution system field check will be conducted in accordance with U.S. EPA Reference Method 205. An initial three (3) point calibration will be conducted, using individual Protocol 1 gases, on the analyzer used to complete the dilution system field check. Multiple dilution rates and total gas flow rates will be utilized to force the dilution system to perform two dilutions on each mass flow controller. The diluted calibration gases will be sent directly to the analyzer, and the analyzer response recorded in an electronic field data sheet. The analyzer response must agree within 2% of the actual diluted gas concentration. A second Protocol 1 calibration gas, with a cylinder concentration within 10% of one of the gas divider settings described above, will be introduced directly to the 57 of 63 Site Specific Test Plan Testing Methodology AST-2023-4493 Nodal Power – Layton, UT Page 3-3 analyzer, and the analyzer response recorded in an electronic field data sheet. The cylinder concentration and the analyzer response must agree within 2%. These steps will be repeated three (3) times. 3.9 Quality Assurance/Quality Control – U.S. EPA Reference Test Methods 3A, 7E and 10 Cylinder calibration gases will meet EPA Protocol 1 (+/- 2%) standards. Copies of all calibration gas certificates will be included in the Quality Assurance/Quality Control Appendix of the report. Low Level gas will be introduced directly to the analyzer. After adjusting the analyzer to the Low Level gas concentration and once the analyzer reading is stable, the analyzer value will be recorded. This process will be repeated for the High Level gas. For the Calibration Error Test, Low, Mid, and High Level calibration gases will be sequentially introduced directly to the analyzer. The Calibration Error for each gas must be within 2.0 percent of the Calibration Span or 0.5 ppmv/% absolute difference. High or Mid Level gas (whichever is closer to the stack gas concentration) will be 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 will be recorded. The analyzer reading will be observed until it reaches a stable value, and this value will be recorded. Next, Low Level gas will be 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) will be recorded. If the Low Level gas is zero gas, the acceptable response must be 5.0 percent of the upscale gas concentration or 0.5 ppm/% (whichever was less restrictive). The analyzer reading will be observed until it reaches a stable value and this value will be recorded. The measurement system response time and initial system bias will be determined from these data. The System Bias for each gas must be within 5.0 percent of the Calibration Span or 0.5 ppmv/% absolute difference. High or Mid Level gas (whichever is closer to the stack gas concentration) will be introduced at the probe. After the analyzer response is stable, the value will be recorded. Next, Low Level gas will be introduced at the probe, and the analyzer value will be recorded once it reaches a stable response. The System Bias for each gas must be within 5.0 percent of the Calibration Span or 0.5 ppmv/% absolute difference or the data is invalidated and the Calibration Error Test and System Bias must be repeated. The Drift between pre- and post-run System Bias must be within 3 percent of the Calibration Span or 0.5 ppmv/% absolute difference or the Calibration Error Test and System Bias must be repeated. To determine the number of sampling points, a gas stratification check will be conducted prior to initiating testing. The pollutant concentrations will be measured at twelve traverse points (as described in Method 1) or three points (16.7, 50.0 and 83.3 percent of the measurement line). Each traverse point will be sampled for a minimum of twice the system response time. If the pollutant concentration at each traverse point do not differ more than 5% or 0.5 ppm/0.3% (whichever is less restrictive) of the average pollutant concentration, then single point sampling will be conducted during the test runs. If the pollutant concentration does not meet these specifications but differs less than 10% or 1.0 ppm/0.5% from the average concentration, then three (3) point sampling will be 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 differs by more than 10% or 1.0 ppm/0.5% from the average concentration, then sampling will be conducted at a minimum of twelve (12) traverse points. Copies of stratification check data will be included in the Quality Assurance/Quality Control Appendix of the report. 58 of 63 Site Specific Test Plan Testing Methodology AST-2023-4493 Nodal Power – Layton, UT Page 3-4 An NO2 – NO converter check will be performed on the analyzer prior to initiating testing or at the completion of testing. An approximately 50 ppm nitrogen dioxide cylinder gas will be introduced directly to the NOx analyzer and the instrument response will be recorded in an electronic data sheet.

The QC checks and procedures described in this section represent an integral part of the overall sampling and analytical scheme. Adherence to prescribed procedures is quite often the most applicable QC check. 4.1 Equipment Field test equipment is assigned a unique, permanent identification number. Prior to mobilizing for the test program, equipment is inspected before being packed to detect equipment problems prior to arriving on site. This minimizes lost time on the job site due to equipment failure. Occasional equipment failure in the field is unavoidable despite the most rigorous inspection and maintenance procedures. Therefore, replacements for critical equipment or components are brought to the job site. Equipment returning from the field is inspected before it is returned to storage. During the course of these inspections, items are cleaned, repaired, reconditioned and recalibrated where necessary. Calibrations are conducted in a manner, and at a frequency, which meets or exceeds U.S. EPA specifications. The calibration procedures outlined in the U.S. EPA Methods, and those recommended within the Quality Assurance Handbook for Air Pollution Measurement Systems: Volume III (EPA-600/R-94/038c, September 1994) are utilized. When these methods are inapplicable, methods such as those prescribed by the American Society for Testing and Materials (ASTM) or other nationally recognized agency may be used. Data obtained during calibrations is checked for completeness and accuracy. Copies of calibration forms are included in the report. The following sections elaborate on the calibration procedures followed by Alliance for these items of equipment.  Dry Gas Meter and Orifice. A full meter calibration using critical orifices as the calibration standard is conducted at least semi-annually, more frequently if required. The meter calibration procedure determines the meter correction factor (Y) and the meter’s orifice pressure differential (ΔH@). Alliance uses approved Alternative Method 009 as a post-test calibration check to ensure that the correction factor has not changed more than 5% since the last full meter calibration. This check is performed after each test series.  Pitot Tubes and Manometers. Type-S pitot tubes that meet the geometric criteria required by U.S. EPA Reference Test Method 2 are assigned a coefficient of 0.84 unless a specific coefficient has been determined from a wind tunnel calibration. If a specific coefficient from a wind tunnel calibration has been obtained that coefficient will be used in lieu of 0.84. Standard pitot tubes that meet the geometric criteria required by U.S. EPA Reference Test Method 2 are assigned a coefficient of 0.99. Any pitot tubes not meeting the appropriate geometric criteria are discarded and replaced. Manometers are verified to be level and zeroed prior to each test run and do not require further calibration.  Temperature Measuring Devices. All thermocouple sensors mounted in Dry Gas Meter Consoles are calibrated semi-annually with a NIST-traceable thermocouple calibrator (temperature simulator) and verified during field use using a second NIST-traceable meter. NIST-traceable thermocouple calibrators are calibrated annually by an outside laboratory.  Digital Calipers. Calipers are calibrated annually by Alliance by using gage blocks that are calibrated annually by an outside laboratory.  Barometer. The barometric pressure is obtained from a nationally recognized agency or a calibrated barometer. Calibrated barometers are checked prior to each field trip against a mercury barometer. The 61 of 63 Site Specific Test Plan Quality Assurance Program AST-2023-4493 Nodal Power – Layton, UT Page 4-2 barometer is acceptable if the values agree within ± 2 percent absolute. Barometers not meeting this requirement are adjusted or taken out of service.  Balances and Weights. Balances are calibrated annually by an outside laboratory. A functional check is conducted on the balance each day it is use in the field using a calibration weight. Weights are re-certified every two (2) years by an outside laboratory or internally. If conducted internally, they are weighed on a NIST traceable balance. If the weight does not meet the expected criteria, they are replaced.  Other Equipment. A mass flow controller calibration is conducted on each Environics system annually following the procedures in the Manufacturer’s Operation manual. Other equipment such as probes, umbilical lines, cold boxes, etc. are routinely maintained and inspected to ensure that they are in good working order. They are repaired or replaced as needed. 4.2 Field Sampling Field sampling will be done in accordance with the Standard Operating Procedures (SOP) for the applicable test method(s). General QC measures for the test program include:  Cleaned glassware and sample train components will be sealed until assembly.  Sample trains will be leak checked before and after each test run.  Appropriate impinger temperatures will be maintained.  The sampling port will be sealed to prevent air from leaking from the port.  Dry gas meter, ΔP, ΔH, temperature and pump vacuum data will be recorded during each sample point.  All raw data will be maintained in organized manner.  All raw data will be reviewed on a daily basis for completeness and acceptability. 62 of 63 Last Page of Report 63 of 63 TEST REPORT SUMMARY CORPORATE OFFICE 255 Grant St. SE, Suite 600 Decatur, AL 35601 256.351.0121 www.alliancetechnicalgroup.com Client Information / Test Location Source Information Nodal Power Engine/Unit ID: LFG Generator Davis Landfill Engine Make/Model: Caterpillar G3520C Layton, Utah Engine Serial Number: GZJ00710 Engine Type: Compression/Spark, Rich/Lean Engine Date of Manufacture: 7/7/1905 Engine Rating: 2,233 HP Regulatory Applicability Project No. DAQE-AN101290026-22 AST-2023-3003 Run No. Run 1 Run 2 Run 3 Average Date 8/10/23 8/10/23 8/10/23 -- Engine Load, % * 88 87 87 88 Nitrogen Oxides Data Emission Rate, lb/hr 1.5 1.4 1.4 1.4 Permit Limit, lb/hr -- -- -- 2.46 Percent of Limit, % -- -- -- 57 Emission Factor, g/HP-hr 0.33 0.32 0.32 0.32 Permit Limit, lb/hr -- -- -- 0.5 Percent of Limit, % -- -- -- 65 Carbon Monoxide Data Emission Rate, lb/hr 11.7 11.2 11.6 11.5 Permit Limit, lb/hr -- -- -- 12.31 Percent of Limit, % -- -- -- 93 Emission Factor, g/HP-hr 2.7 2.6 2.7 2.7 Permit Limit, lb/hr -- -- -- 2.5 Percent of Limit, % -- -- -- > 100 Non- Methane HC Data Emission Rate, lb/hr 0.70 0.70 0.73 0.71 Permit Limit, lb/hr -- -- -- 4.33 Percent of Limit, % -- -- -- 16 Emission Factor, g/HP-hr 0.16 0.16 0.17 0.16 Permit Limit, lb/hr -- -- -- 0.88 Percent of Limit, % -- -- -- 19 * Performance testing was conducted while the engine was operating at the highest achievable load at current site conditions.

Portions of the facility are subject to provisions of the Utah Department of Environmental Quality – Division of Air Quality (UDAQ) Permit No. DAQE-AN101290026-22. Testing was conducted at the exhaust of the new landfill gas (LFG) generator engine. Compliance testing was conducted to determine the emission rates of nitrogen oxides (NOx), carbon monoxide (CO) and volatile organic compounds (VOC). Testing consisted of three (3) 60-minute test runs for the source. Performance testing was conducted while the engine was operating at the highest achievable load at current site conditions. The Test Report Summary (TRS) provides the results from the compliance testing, including the three (3) run average, with comparisons to the applicable limits. Any difference between the summary results listed in the TRS and the detailed results contained in the appendices is due to rounding for presentation. 1.1 Facility and Process Description Wasatch Integrated Waste Management District operates Davis Landfill, a municipal solid waste (MSW) landfill located in Davis County, Utah.

Method descriptions are provided below while quality assurance/quality control data is provided in Appendix C. Table 2-1: Source Testing Methodology Parameter U.S. EPA Reference Test Methods Notes/Remarks Volumetric Flow Rate 1 & 2 Full Velocity Traverses Oxygen/Carbon Dioxide 3A Instrumental Analysis Moisture Content 4 Gravimetric Analysis Nitrogen Oxides 7E Instrumental Analysis Carbon Monoxide 10 Instrumental Analysis (Non-Methane) Hydrocarbons 25A Instrumental Analysis Gas Dilution System Certification 205 -- 2.1 U.S. EPA Reference Test Methods 1 & 2 – Volumetric Flow Rate The sampling location and number of traverse (sampling) points were selected in accordance with U.S. EPA Reference Test Method 1. To determine the minimum number of traverse points, the upstream and downstream distances were equated into equivalent diameters and compared to Figure 1-2 in U.S. EPA Reference Test Method 1. 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. 2.2 U.S. EPA Reference Test Method 3A – Oxygen/Carbon Dioxide The oxygen (O2) and carbon dioxide (CO2) testing were 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. Sampling was conducted at three traverse points passing through the centroidal area of the duct (rake probe for strat). The quality control measures are described in Section 2.8. 2.3 U.S. EPA Reference Test Method 4 – Moisture Content The stack gas moisture content was determined in accordance with U.S. EPA Reference Test Method 4. The gas conditioning train consisted of a series of chilled impingers. The impingers were pre and post-measured to determine the amount of moisture condensed during each test run. 8 of 78 Source Test Report Testing Methodology AST-2023-3003 Nodal Power – Layton, UT Page 2-2 2.4 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 2.8. 2.5 U.S. EPA Reference Test Method 10 – 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 from 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 2.8. 2.6 U.S. EPA Reference Test Method 25A – Non Methane Hydrocarbons The non-methane hydrocarbon (NMHC) testing was conducted in accordance with U.S. EPA Reference Test Method 25A. Data was collected online and reported in one-minute averages. The sampling system consisted of a stainless steel probe, heated Teflon sample line(s) and the identified gas analyzer equipped with a non-methane cutter. The quality control measures are described in Section 2.9. 2.7 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 1 calibration gas, with a cylinder concentration within 10% 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 2%. These steps were repeated three (3) times. Copies of the Method 205 data can be found in the Quality Assurance/Quality Control Appendix. 2.8 Quality Assurance/Quality Control – U.S. EPA Reference Methods 3A, 7E and 10 Cylinder calibration gases used met EPA Protocol 1 (+/- 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 Mid Level gas. Next, High Level gas was introduced directly to the analyzer, and the response recorded when it was stable. 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 9 of 78 Source Test Report Testing Methodology AST-2023-3003 Nodal Power – Layton, UT Page 2-3 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 between pre- and post-run System Bias was within 0.5 ppmv absolute difference or 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% or 0.5 ppm (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 10% or 1.0 ppm 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 10% or 1.0 ppm 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 NO2 – NO converter check was performed on the analyzer prior to initiating 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 +/- 10 percent of the cylinder concentration. A Data Acquisition System (Dutech Analog Signal Modules) with battery backup was used to record the instrument response in one (1) 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. 2.9 Quality Assurance/Quality Control – U.

After adjusting the analyzer to the Zero gas concentration and once the analyzer reading was stable, the analyzer value was recorded. This process was repeated for the High Level gas, and the time required for the analyzer reading to reach 95 percent of the gas concentration was recorded to determine the response time. Next, Low and Mid Level gases were introduced through the sampling system to the analyzer, and the response was recorded when it was stable. All values were less than +/- 5 percent of the calibration gas concentrations. Mid Level gas was introduced through the sampling system. After the analyzer response was stable, the value was recorded. Next, Zero gas was introduced through the sampling system, and the analyzer value recorded once it reached a stable response. The Analyzer Drift was less than +/- 3 percent of the span value. A Data Acquisition System (Dutech Analog Signal Modules) with battery backup was used to record the instrument response in one (1) 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.

EPA Method 25A is incorporated by reference. The sampling system will consist of a stainless steel probe, heated Teflon sample line(s) and a Thermo 55i analyzer. VOC data will be collected in one (1) minute averages. The quality control measures are described in Section 3.11. 3.8 U.S. EPA Reference Test Method 205 – Gas Dilution System Certification A calibration gas dilution system field check will be conducted in accordance with U.S. EPA Reference Method 205. An initial three (3) point calibration will be conducted, using individual Protocol 1 gases, on the analyzer used to complete the dilution system field check. Multiple dilution rates and total gas flow rates will be utilized to force the dilution system to perform two dilutions on each mass flow controller. The diluted calibration gases will be sent directly to the analyzer, and the analyzer response recorded in an electronic field data sheet. The analyzer response must agree within 2% of the actual diluted gas concentration. A second Protocol 1 calibration gas, with a cylinder concentration within 10% of one of the gas divider settings described above, will be introduced directly to the 57 of 78 Site Specific Test Plan Testing Methodology AST-2023-2904 Nodal Power – Layton, UT Page 3-3 analyzer, and the analyzer response recorded in an electronic field data sheet. The cylinder concentration and the analyzer response must agree within 2%. These steps will be repeated three (3) times. 3.9 Quality Assurance/Quality Control – U.S. EPA Reference Test Methods 3A, 7E and 10 Cylinder calibration gases will meet EPA Protocol 1 (+/- 2%) standards. Copies of all calibration gas certificates will be included in the Quality Assurance/Quality Control Appendix of the report. Low Level gas will be introduced directly to the analyzer. After adjusting the analyzer to the Low Level gas concentration and once the analyzer reading is stable, the analyzer value will be recorded. This process will be repeated for the High Level gas. For the Calibration Error Test, Low, Mid, and High Level calibration gases will be sequentially introduced directly to the analyzer. The Calibration Error for each gas must be within 2.0 percent of the Calibration Span or 0.5 ppmv/% absolute difference. High or Mid Level gas (whichever is closer to the stack gas concentration) will be 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 will be recorded. The analyzer reading will be observed until it reaches a stable value, and this value will be recorded. Next, Low Level gas will be 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) will be recorded. If the Low Level gas is zero gas, the acceptable response must be 5.0 percent of the upscale gas concentration or 0.5 ppm/% (whichever was less restrictive). The analyzer reading will be observed until it reaches a stable value and this value will be recorded. The measurement system response time and initial system bias will be determined from these data. The System Bias for each gas must be within 5.0 percent of the Calibration Span or 0.5 ppmv/% absolute difference. High or Mid Level gas (whichever is closer to the stack gas concentration) will be introduced at the probe. After the analyzer response is stable, the value will be recorded. Next, Low Level gas will be introduced at the probe, and the analyzer value will be recorded once it reaches a stable response. The System Bias for each gas must be within 5.0 percent of the Calibration Span or 0.5 ppmv/% absolute difference or the data is invalidated and the Calibration Error Test and System Bias must be repeated. The Drift between pre- and post-run System Bias must be within 3 percent of the Calibration Span or 0.5 ppmv/% absolute difference or the Calibration Error Test and System Bias must be repeated. To determine the number of sampling points, a gas stratification check will be conducted prior to initiating testing. The pollutant concentrations will be measured at twelve traverse points (as described in Method 1) or three points (16.7, 50.0 and 83.3 percent of the measurement line). Each traverse point will be sampled for a minimum of twice the system response time. If the pollutant concentration at each traverse point do not differ more than 5% or 0.5 ppm/0.3% (whichever is less restrictive) of the average pollutant concentration, then single point sampling will be conducted during the test runs. If the pollutant concentration does not meet these specifications but differs less than 10% or 1.0 ppm/0.5% from the average concentration, then three (3) point sampling will be 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 differs by more than 10% or 1.0 ppm/0.5% from the average concentration, then sampling will be conducted at a minimum of twelve (12) traverse points. Copies of stratification check data will be included in the Quality Assurance/Quality Control Appendix of the report. 58 of 78 Site Specific Test Plan Testing Methodology AST-2023-2904 Nodal Power – Layton, UT Page 3-4 An NO2 – NO converter check will be performed on the analyzer prior to initiating testing or at the completion of testing. An approximately 50 ppm nitrogen dioxide cylinder gas will be introduced directly to the NOx analyzer and the instrument response will be recorded in an electronic data sheet. The instrument response must be within +/- 10 percent of the cylinder concentration. A Data Acquisition System with battery backup will be used to record the instrument response in one (1) minute averages. The data will be continuously stored as a *.CSV file in Excel format on the hard drive of a computer. At the completion of testing, the data will also be saved to the Alliance server. All data will be reviewed by the Field Team Leader before leaving the facility. Once arriving at Alliance’s office, all written and electronic data will be relinquished to the report coordinator and then a final review will be performed by the Project Manager. 3.10 Quality Assurance/Quality Control – U.S. EPA Reference Test Method 25A Cylinder calibration gases will meet EPA Protocol 1 (+/- 2%) standards. Copies of all calibration gas certificates will be included in the Quality Assurance/Quality Control Appendix of the report. Within two (2) hours prior to testing, zero gas will be introduced through the sampling system to the analyzer. After adjusting the analyzer to the Zero gas concentration and once the analyzer reading is stable, the analyzer value will be recorded. This process will be repeated for the High Level gas, and the time required for the analyzer reading to reach 95 percent of the gas concentration will be recorded to determine the response time. Next, Low and Mid Level gases will be introduced through the sampling system to the analyzer, and the response will be recorded when it is stable. All values must be less than +/- 5 percent of the calibration gas concentrations. Mid Level gas will be introduced through the sampling system. After the analyzer response is stable, the value will be recorded. Next, Zero gas will be introduced through the sampling system, and the analyzer value recorded once it reaches a stable response. The Analyzer Drift must be less than +/- 3 percent of the span value. A Data Acquisition System with battery backup will be used to record the instrument response in one (1) minute averages. The data will be continuously stored as a *.CSV file in Excel format on the hard drive of a computer. At the completion of testing, the data will also be saved to the Alliance server. All data will be reviewed by the Field Team Leader before leaving the facility. Once arriving at Alliance’s office, all written and electronic data will be relinquished to the report coordinator and then a final review will be performed by the Project Manager. 3.11 Quality Assurance/Quality Control – U.S. EPA Reference Method ALT-096 EPA Protocol 1 Calibration Gases – Cylinder calibration gases used will meet EPA Protocol 1 (+/- 2%) standards. Copies of all calibration gas certificates will be provided in the Quality Assurance/Quality Control Appendix. Zero gas will be introduced through the sampling system to the analyzer. After adjusting the analyzer to the Zero gas concentration and once the analyzer reading is stable, the analyzer value will be recorded. This process will be repeated for the High Level gas, and the time required for the analyzer reading to reach 95 percent of the gas concentration will be recorded to determine the response time. Next, Mid and Low Level gases will be introduced through the sampling system to the analyzer, and the response will be recorded when it is stable. All values must be within +/- 5% of the calibration gas concentrations. 59 of 78 Site Specific Test Plan Testing Methodology AST-2023-2904 Nodal Power – Layton, UT Page 3-5 Post Test Drift Checks – Mid Level gas will be introduced through the sampling system. After the analyzer response is stable, the value will be recorded. Next, Zero gas will be introduced through the sampling system, and the analyzer value recorded once it reaches a stable response. The Analyzer Drift must be less than 3 percent of the Calibration Span. Data Collection – A Data Acquisition System with battery backup will be used to record the instrument response (analog 0-10 volt signal) in one (1) minute averages. The data will be continuously stored as a *.CSV file in Excel format on the hard drive of a desktop computer. At the completion of the emissions testing the data will be also saved to the Alliance server. All data will be reviewed by the Field Team Leader before leaving the facility. Once arriving at Alliance’s office, all written and electronic data will be relinquished to the report coordinator and then a final review will be performed by the Project Manager. 60 of 78 Site Specific Test Plan Quality Assurance Program AST-2023-2904 Nodal Power – Layton, UT Page 4-1 4.0 Quality Assurance Program Alliance follows the procedures outlined in the Quality Assurance/Quality Control Management Plan to ensure the continuous production of useful and valid data throughout the course of this test program. The QC checks and procedures described in this section represent an integral part of the overall sampling and analytical scheme. Adherence to prescribed procedures is quite often the most applicable QC check. 4.1 Equipment Field test equipment is assigned a unique, permanent identification number. Prior to mobilizing for the test program, equipment is inspected before being packed to detect equipment problems prior to arriving on site. This minimizes lost time on the job site due to equipment failure. Occasional equipment failure in the field is unavoidable despite the most rigorous inspection and maintenance procedures. Therefore, replacements for critical equipment or components are brought to the job site. Equipment returning from the field is inspected before it is returned to storage. During the course of these inspections, items are cleaned, repaired, reconditioned and recalibrated where necessary. Calibrations are conducted in a manner, and at a frequency, which meets or exceeds U.S. EPA specifications. The calibration procedures outlined in the U.S. EPA Methods, and those recommended within the Quality Assurance Handbook for Air Pollution Measurement Systems: Volume III (EPA-600/R-94/038c, September 1994) are utilized. When these methods are inapplicable, methods such as those prescribed by the American Society for Testing and Materials (ASTM) or other nationally recognized agency may be used. Data obtained during calibrations is checked for completeness and accuracy. Copies of calibration forms are included in the report. The following sections elaborate on the calibration procedures followed by Alliance for these items of equipment.  Dry Gas Meter and Orifice. A full meter calibration using critical orifices as the calibration standard is conducted at least semi-annually, more frequently if required. The meter calibration procedure determines the meter correction factor (Y) and the meter’s orifice pressure differential (ΔH@). Alliance uses approved Alternative Method 009 as a post-test calibration check to ensure that the correction factor has not changed more than 5% since the last full meter calibration. This check is performed after each test series.  Pitot Tubes and Manometers. Type-S pitot tubes that meet the geometric criteria required by U.S. EPA Reference Test Method 2 are assigned a coefficient of 0.84 unless a specific coefficient has been determined from a wind tunnel calibration. If a specific coefficient from a wind tunnel calibration has been obtained that coefficient will be used in lieu of 0.84. Standard pitot tubes that meet the geometric criteria required by U.S. EPA Reference Test Method 2 are assigned a coefficient of 0.99. Any pitot tubes not meeting the appropriate geometric criteria are discarded and replaced. Manometers are verified to be level and zeroed prior to each test run and do not require further calibration.  Temperature Measuring Devices. All thermocouple sensors mounted in Dry Gas Meter Consoles are calibrated semi-annually with a NIST-traceable thermocouple calibrator (temperature simulator) and verified during field use using a second NIST-traceable meter. NIST-traceable thermocouple calibrators are calibrated annually by an outside laboratory.  Nozzles. Nozzles are measured three (3) times prior to initiating sampling with a caliper. The maximum difference between any two (2) dimensions is 0.004 in.  Digital Calipers. Calipers are calibrated annually by Alliance by using gage blocks that are calibrated annually by an outside laboratory. 61 of 78 Site Specific Test Plan Quality Assurance Program AST-2023-2904 Nodal Power – Layton, UT Page 4-2  Barometer. The barometric pressure is obtained from a nationally recognized agency or a calibrated barometer. Calibrated barometers are checked prior to each field trip against a mercury barometer. The barometer is acceptable if the values agree within ± 2 percent absolute. Barometers not meeting this requirement are adjusted or taken out of service.  Balances and Weights. Balances are calibrated annually by an outside laboratory. A functional check is conducted on the balance each day it is use in the field using a calibration weight. Weights are re-certified every two (2) years by an outside laboratory or internally. If conducted internally, they are weighed on a NIST traceable balance. If the weight does not meet the expected criteria, they are replaced.  Other Equipment. A mass flow controller calibration is conducted on each Environics system annually following the procedures in the Manufacturer’s Operation manual. Other equipment such as probes, umbilical lines, cold boxes, etc. are routinely maintained and inspected to ensure that they are in good working order. They are repaired or replaced as needed. 4.2 Field Sampling Field sampling will be done in accordance with the Standard Operating Procedures (SOP) for the applicable test method(s). General QC measures for the test program include:  Cleaned glassware and sample train components will be sealed until assembly.  Sample trains will be leak checked before and after each test run.  Appropriate probe, filter and impinger temperatures will be maintained.  The sampling port will be sealed to prevent air from leaking from the port.  Dry gas meter, ΔP, ΔH, temperature and pump vacuum data will be recorded during each sample point.  All raw data will be maintained in organized manner.  All raw data will be reviewed on a daily basis for completeness and acceptability. 62 of 78 SSTP-Appendix A 63 of 78 Method 1 Data Location Source Project No. Date in in 0.00 in --ft2 -- ft --(must be > 0.5) ft --(must be > 2) 0 Measurer (Initial and Date): Reviewer (Initial and Date): 2 3 4 5 6 7 8 9 10 11 12 1 25.0 16.7 12.5 10.0 8.3 7.1 6.3 5.6 5.0 4.5 4.2 1 -- -- -- 2 75.0 50.0 37.5 30.0 25.0 21.4 18.8 16.7 15.0 13.6 12.5 2 -- -- -- 3 -- 83.3 62.5 50.0 41.7 35.7 31.3 27.8 25.0 31.8 20.8 3 -- -- -- 4 -- -- 87.5 70.0 58.3 50.0 43.8 38.9 35.0 22.7 29.2 4 -- -- -- 5 -- -- -- 90.0 75.0 64.3 56.3 50.0 45.0 40.9 37.5 5 -- -- -- 6 -- -- -- -- 91.7 78.6 68.8 61.1 55.0 50.0 45.8 6 -- -- -- 7 -- -- -- -- -- 92.9 81.3 72.2 65.0 59.1 54.2 7 -- -- -- 8 -- -- -- -- -- -- 93.8 83.3 75.0 68.2 62.5 8 -- -- -- 9 -- -- -- -- -- -- -- 94.4 85.0 77.3 70.8 9 -- -- -- 10 -- -- -- -- -- -- -- -- 95.0 86.4 79.2 10 -- -- -- 11 -- -- -- -- -- -- -- -- -- 95.5 87.5 11 -- -- -- 12 -- -- -- -- -- -- -- -- -- -- 95.8 12 -- -- -- *Percent of stack diameter from inside wall to traverse point.
