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). The Gencor 400 TPH Drum Mix HMA is limited to 728,000 tons of aphalt production per rolling 12-month period and 5,600 tons of asphalt per day. The static differential pressure across the baghouse must be maintained between 2.0 to 5.0 inches of water column on the pressure gauge. 9 of 88 GP081AS-046104-RT-1766 Staker Parson, Huntington Asphalt and Aggregate Pit 2024 Compliance Source Test Report, Gencor 400 TPH Drum Mix HMA Plant, Near Huntington, Utah 2.2 Flue Gas Sampling Location Table 2-1 presents the stack measurements and traverse points for the sampling location listed.

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 samples or measurements of volumetric flow rate of each Stack 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 Gas Velocity and Volumetric Flow Rate (Type S Pitot Tube) EPA Method 2 is used to measure the gas velocity of each Stack 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. 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. The typical sampling system is detailed as part of the EPA Methods 5 and 202 sampling train in Figure 3-1. 11 of 88 GP081AS-046104-RT-1766 Staker Parson, Huntington Asphalt and Aggregate Pit 2024 Compliance Source Test Report, Gencor 400 TPH Drum Mix HMA Plant, Near Huntington, 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 gas by measuring the percent O2 and CO2 in the gas stream. A gas sample is extracted from the stack by one of the following methods: (1) single-point, grab sampling; (2) single-point, integrated sampling; or (3) multi-point, integrated sampling. The gas sample is analyzed for percent CO2 and percent O2 using either an Orsat or a Fyrite analyzer. 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 Single-point integrated sampling is performed. o Less than 28 L (1.0 ft3) is collected. • Target and/or Minimum Required Sample Duration: 60 minutes • Target and/or Minimum Recommended Sample Volume: 1.0 ft3 • Target Analytes: O2 and CO2 3.1.4 EPA Method 4, Determination of Moisture Content in Stack Gas EPA Method 4 is a manual, non-isokinetic 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 Moisture sampling is performed as part of the pollutant (Method 5) sample trains. 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 As the EPA Method 5 sampling train was used to collect moisture, sampling was not constant; rather, sampling was isokinetic as per the criteria set forth in EPA Method 5. The typical sampling system is detailed as part of the EPA Methods 5 and 202 sampling train in Figure 3-1. 12 of 88 GP081AS-046104-RT-1766 Staker Parson, Huntington Asphalt and Aggregate Pit 2024 Compliance Source Test Report, Gencor 400 TPH Drum Mix HMA Plant, Near Huntington, 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: • Glass sample nozzles and probe liners are used. • Condensed water is measured gravimetrically. • As an alternative to baking glassware, a field train proof blank sample was recovered. • The post-test nitrogen purge was performed using the sampling system meter box and vacuum pump. • Method 5 results are used to demonstrate compliance with the individual PM and PM10 emission limits. • Target Sample Duration: 60 minutes • Minimum Required Sample Volume: 31.8 dscf (0.90 dscm) • 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. As the average calculated meter box percent (%) error resulted in a percent error within ±5% of Y, a full calibration was not performed. o EPA Approved Alternative Method 011 (ALT-011) was used as an alternative to the EPA Method 2 two-point thermocouple calibration. This procedure involved a single-point in-field check using a reference thermometer to confirm that the thermocouple system was operating properly. The temperatures of the thermocouple and reference thermometers agreed to within ±2 ºF. The typical sampling system is detailed in Figure 3-1. 13 of 88 GP081AS-046104-RT-1766 Staker Parson, Huntington Asphalt and Aggregate Pit 2024 Compliance Source Test Report, Gencor 400 TPH Drum Mix HMA Plant, Near Huntington, Utah Figure 3-1 EPA Methods 5 and 202 Sampling Train 3.1.6 EPA Method 9, Visual Determination of the Opacity of Emissions EPA Method 9 is used to observe the visual opacity of emissions (opacity). 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. o Observations are attempted to be made during each concurrent particulate run, unless weather conditions are unfavorable. o Total Observation Period Duration: 6 minutes per run 14 of 88 GP081AS-046104-RT-1766 Staker Parson, Huntington Asphalt and Aggregate Pit 2024 Compliance Source Test Report, Gencor 400 TPH Drum Mix HMA Plant, Near Huntington, Utah 4.0 Test Discussion and Results 4.1 Field Test Deviations and Exceptions No field deviations or exceptions from the test plan or test methods were reported by the test crew during this test program. 4.2 Presentation of Results The average results are compared to the permit limits in Table 1-2.
