1.0 Introduction 1.1 Summary of Test Program Staker Parson contracted Montrose Air Quality Services, LLC (Montrose) to perform a compliance emissions test program on the following units at the facility to be located near White Mesa, San Juan County, UT: Astec 600 TPH Portable HMAP. The tests are conducted to determine the emissions of PM/PM10 and the opacity of emissions (VEs) from the exhaust of the HMAP. Also, as this same portable HMAP is anticipated to be put in service at the Spanish Valley Pit later in the year (past the test date proposed in this test plan), testing will be conducted to determine the portable HMAP’s compliance status with Permit Condition II.B.5 contained in Utah Department of Environmental Quality (UDEQ) Approval Order (AO) DAQE-AN159360002-20, issued October 20, 2020. It is hoped that the test results from this test program also demonstrate compliance with the emission limitations contained in AO DAQE-AN159360002-20. The portable HMAP is also subject to 40 CFR Part 60, Subpart I emission limits. The specific objectives are to: • Measure emissions of PM/PM10 at the outlet of the Astec 600 TPH Portable HMA Plant, controlled by a baghouse. • Determine the opacity of emissions (VEOs) at the outlet of the Astech 600 TPH Portable HMA Plant, controlled by a baghouse. • Conduct the test program with a focus on safety. Montrose will provide the test personnel and the necessary equipment to measure emissions as outlined in this test plan. Facility personnel will provide the process and production data to be included in the final report. A summary of the test program and proposed schedule is presented in Table 1-1.

Aggregate constitutes 92 weight percent of the total mixture. Aside from the amount and grade of asphalt used, mix characteristics are determined by the relative amounts and types of aggregate used. A certain percentage of fine aggregate (% less than 74 micrometers in physical diameter) is required to produce good quality asphaltic concrete. The drum mix process simplifies the conventional process by using proportioning feed controls in place of hot aggregate storage bins, vibration screens, and the mixer. Aggregate is introduced near the burner end of the revolving drum mixer, and the asphalt is injected midway along the drum. A variable flow asphalt pump is linked electronically to the aggregate belt scales to control mix specifications. The hot mix is discharged from the revolving drum mixer into surge bins or storage bins. Emissions from the asphalt drum mixer are vented to a baghouse before being emitted to the atmosphere. The pressure drop across the baghouse will be maintained between 2 and 6 inches of water column. The estimated removal efficiency for the baghouse is 99+ percent for total suspended particulate material (and PM10). 2.2 Flue Gas Sampling Location Actual stack measurements, number of traverse points, and location of traverse points will be evaluated in the field as part of the test program. Table 2-1 presents the anticipated stack measurements and traverse points for the sampling locations listed. Table 2-1 Sampling Location Sampling Location Stack Inside Diameter (in.)

Staker Parson Companies 2025 Compliance Source Test Plan, Astech 600 TPH Portable HMA Plant, Near White Mesa, Utah 3.0 Sampling and Analytical Procedures 3.1 Test Methods The test methods for this test program have been presented in Table 1-1. Additional information regarding specific applications or modifications to standard procedures is presented below. 3.1.1 EPA Method 1, Sample and Velocity Traverses for Stationary Sources EPA Method 1 is used to assure that representative measurements of volumetric flow rate are obtained by dividing the cross-section of the stack or duct into equal areas, and then locating a traverse point within each of the equal areas. Acceptable sample locations must be located at least two stack or duct equivalent diameters downstream from a flow disturbance and one-half equivalent diameter upstream from a flow disturbance. 3.1.2 EPA Method 2, Determination of Stack Gas Velocity and Volumetric Flow Rate (Type S Pitot Tube) EPA Method 2 is used to measure the gas velocity using an S-type pitot tube connected to a pressure measurement device, and to measure the gas temperature using a calibrated thermocouple connected to a thermocouple indicator. Typically, Type S (Stausscheibe) pitot tubes conforming to the geometric specifications in the test method are used, along with an inclined manometer. The measurements are made at traverse points specified by EPA Method 1. The molecular weight of the gas stream is determined from independent measurements of O2, CO2, and moisture content. The stack gas volumetric flow rate is calculated using the measured average velocity head, the area of the duct at the measurement plane, the measured average temperature, the measured duct static pressure, the molecular weight of the gas stream, and the measured moisture. Pertinent information regarding the performance of the method is presented below: o S-type pitot tube coefficient is 0.84. o Shortridge multimeter may be used to measure velocity. The typical sampling system is detailed as part of the EPA Method 5/202 sampling train in Figure 3-1. Staker Parson Companies 2025 Compliance Source Test Plan, Astech 600 TPH Portable HMA Plant, Near White Mesa, Utah 3.1.3 EPA Method 3, Gas Analysis for the Determination of Dry Molecular Weight EPA Method 3 is used to calculate the dry molecular weight of the stack via measurement of the percent O2 and CO2 in the gas stream. A gas sample is extracted from a stack by multi- point, integrated sampling. The gas sample is analyzed for percent CO2 and percent O2 using either an Orsat or a Fyrite analyzer. Alternatively, an assigned value of 30.0 lb/lb-mol, in lieu of actual measurements, is used for processes burning natural gas, coal, or oil. Pertinent information regarding the performance of the method is presented below: • Method Options: o An Orsat analyzer is used to measure the analyte concentrations. o Multi-point integrated sampling is performed. • Method Exceptions: o A value of 30.0 is assigned for dry molecular weight, in lieu of actual measurements, for processes burning natural gas, coal, or oil. • Target and/or Minimum Required Sample Duration: 60 minutes • Target and/or Minimum Recommended Sample Volume: 1.0 ft3 • Target Analytes: O2 and CO2 Staker Parson Companies 2025 Compliance Source Test Plan, Astech 600 TPH Portable HMA Plant, Near White Mesa, Utah 3.1.4 EPA Method 4, Determination of Moisture Content in Stack Gas EPA Method 4 is a manual method used to measure the moisture content of gas streams. Gas is sampled at a constant sampling rate through a probe and impinger train. Moisture is removed using a series of pre-weighed impingers containing methodology-specific liquids and silica gel immersed in an ice water bath. The impingers are weighed after each run to determine the percent moisture. Pertinent information regarding the performance of the method is presented below: o Condensed water is measured gravimetrically. o Since it is theoretically impossible for measured moisture to be higher than psychrometric moisture, the psychrometric moisture is also calculated, and the lower moisture value is used in the calculations. o Minimum Required Sample Volume: 21 scf o Moisture content is determined from the EPA Methods 5 and 202 sampling training. In this case, gas is sampled at an isokinetic rate, not constant. o Method Options: o EPA Approved Alternative Method 009 (ALT-009) is used as an alternative to a two-point post-test meter box calibration. This procedure uses a calculation to check the meter box calibration factor rather than requiring a physical post-test meter box calibration using a standard dry gas meter. The average calculated meter box percent (%) error must result in a percent error within ±5% of Y. If not, a full calibration is performed, and the results are presented using the Y factor that yields the highest emissions. o EPA Approved Alternative Method 011 (ALT-011) is used as an alternative to the EPA Method 2 two-point thermocouple calibration. This procedure involves a single-point in-field check using a reference thermometer to confirm that the thermocouple system is operating properly. The temperatures of the thermocouple and reference thermometers shall agree to within ±2 °F. The typical sampling system is detailed in Figure 3-1 as part of the EPA Method 2 and 4 sampling train. Staker Parson Companies 2025 Compliance Source Test Plan, Astech 600 TPH Portable HMA Plant, Near White Mesa, Utah 3.1.5 EPA Methods 5 and 202, Determination of Particulate Matter from Stationary Sources and Dry Impinger Method for Determining Condensable Particulate Emissions from Stationary Sources EPA Methods 5 and 202 are manual, isokinetic methods used to measure FPM and CPM emissions. The methods are performed in conjunction with EPA Methods 1, 2, 3, and 4. The stack gas is sampled through a nozzle, probe, heated filter, unheated CPM filter, condenser, and impinger train. FPM is collected from the probe and heater filter. CPM is collected from the unheated CPM filter and the impinger train. The samples are analyzed gravimetrically. The sum of FPM and CPM represents TPM. The FPM, CPM, and TPM results are reported in emission concentration and emission rate units. Pertinent information regarding the performance of the method is presented below: • Method Options: o Glass sample nozzles and probe liners are used. o Stainless steel sample nozzles and glass probe liners are used. o As an alternative to baking glassware, a field train proof blank sample is recovered. o The post-test nitrogen purge is performed using the sampling system meter box and vacuum pump. o The post-test nitrogen purge is performed by passing nitrogen through the train under pressure. • Method Exceptions: o Stainless steel probe liners are used. o A heated flexible probe extension is used to connect the sample probe to the impinger box. o Single-point isokinetic sampling is performed at this stack due to space restrictions. o The sum of the filterable PM (via Method 5) and CPM (via Method 202) are used as a surrogate for PM10 and/or PM2.5. • Target and/or Minimum Required Sample Duration: 60 minutes • Analytical Laboratory: MAQS, Spanish Fork, Utah The typical sampling system is detailed in Figure 3-1.

The observer stands at a distance sufficient to provide a clear view of the emissions with the sun oriented in the 140° sector to their back. The line of vision is perpendicular to the plume direction and does not include more than one plume diameter. Observations are recorded at 15- second intervals and are made to the nearest 5% opacity. The qualified observer is certified according to the requirements of EPA Method 9, section 3.1. Pertinent information regarding the performance of the method is presented below: • Method Options: o Averaging period is 6 minutes (40 CFR Part 60, Subpart I). Observations are attempted to be made 30 minutes before, during, or within 30 minutes after each concurrent particulate run, unless weather conditions are unfavorable. 3.2 Process Test Methods The applicable regulations do not require process samples to be collected during this test program. Staker Parson Companies 2025 Compliance Source Test Plan, Astech 600 TPH Portable HMA Plant, Near White Mesa, Utah 4.0 Quality Assurance and Reporting 4.1 QA Audits Montrose has instituted a rigorous QA/QC program for its air quality testing. Quality assurance audits are performed as part of the test program to ensure that the results are calculated using the highest quality data available. This program ensures that the emissions data we report are as accurate as possible. The procedures included in the cited reference methods are followed during preparation, sampling, calibration, and analysis. Montrose is responsible for preparation, calibration, and cleaning of the sampling apparatus. Montrose will also perform the sampling, sample recovery, storage, and shipping. Approved contract laboratories may perform some of the preparation and sample analyses, as needed. 4.2 Quality Control Procedures Montrose calibrates and maintains equipment as required by the methods performed and applicable regulatory guidance. Montrose follows internal procedures to prevent the use of malfunctioning or inoperable equipment in test programs. All equipment is operated by trained personnel. Any incidence of nonconforming work encountered during testing is reported and addressed through the corrective action system. 4.2.1 Equipment Inspection and Maintenance Each piece of field equipment that requires calibration is assigned a unique identification number to allow tracking of its calibration history. All field equipment is visually inspected prior to testing and includes pre-test calibration checks as required by the test method or regulatory agency. 4.2.2 Audit Samples When required by the test method and available, Montrose obtains EPA TNI SSAS audit samples from an accredited provider for analysis along with the samples. Currently, the SSAS program has been suspended pending the availability of a second accredited audit sample provider. If the program is reinstated, the audit samples will be ordered. If required as part of the test program, the audit samples are stored, shipped, and analyzed along with the emissions samples collected during the test program. The audit sample results are reported along with the emissions sample results. 4.3 Data Analysis and Validation Montrose converts the raw field, laboratory, and process data to reporting units consistent with the permit or subpart. Calculations are made using proprietary computer spreadsheets or data acquisition systems. One run of each test method is also verified using a separate example calculation. The example calculations are checked against the spreadsheet results and are included in the final report. The “Standard Conditions” for this project are 29.92 inches of mercury and 68 °F. Staker Parson Companies 2025 Compliance Source Test Plan, Astech 600 TPH Portable HMA Plant, Near White Mesa, Utah 4.4 Sample Identification and Custody The on-site Field Project Manager will assume or assign the role of sample and data custodian until relinquishing custody.
