To produce HMA, raw materials such as sand, coarse aggregate, lime, fly ash, asphalt oil, and/or recycled asphalt pavement (RAP) is brought on site and stored. Sand, coarse aggregate, and RAP are stockpiled; lime and fly ash are pneumatically loaded into silos; and asphalt oil is unloaded into storage tanks. The stockpiled aggregate materials are sized and sorted via crushers, conveyors and screens. The aggregate materials are then dried and mixed with lime and asphalt in a heated mixer to produce HMA. The finished HMA product is stored in silos on site and unloaded into trucks for sale and distribution. This facility is powered via line power, apart from the natural gas-fired, hot mix asphalt counter-flow drum burner. A baghouse is employed to process stream emissions from the HMA plant exhaust. The HMA plant has a maximum production rate of 500 tons per hour (tph) and 80,000 tons of HMA per rolling 12-month period; it may be fired on natural gas, propane, #1 or #2 fuel oil, or on-specification used oil. 8 of 89 GP081AS-041316-RT-1661 Kilgore Companies, West Valley, UT Dillman 500 TPH Portable Counter-flow Hot Mix Asphalt Plant 2024 PM, PM10, and PM2.5 and VEs Compliance Test Report 2.2 Flue Gas Sampling Locations Actual stack measurements, number of traverse points, and location of traverse points were evaluated in the field as part of the test program.

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 Method 5/202 sampling train in Figure 3-1. 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 single-point, integrated sampling. The gas sample is analyzed for percent CO2 and percent O2 using an Orsat analyzer. 10 of 89 GP081AS-041316-RT-1661 Kilgore Companies, West Valley, UT Dillman 500 TPH Portable Counter-flow Hot Mix Asphalt Plant 2024 PM, PM10, and PM2.5 and VEs Compliance Test Report Pertinent information regarding the performance of the method is presented below: • Target and/or Minimum Required Sample Duration: 62.5 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 used to measure the moisture content of gas streams. Gas is sampled 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 5/202) sample trains o Minimum Required Sample Volume: 21 scf As the EPA Method 5/202 sampling train were used to collect moisture, sampling was not constant; rather, sampling was isokinetic as per the criteria set forth in EPA Methods 5/202. The typical sampling system is detailed as part of the EPA Method 5/202 sampling train in Figure 3-1. 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 through 4. A glass probe liner was used and maintained at a temperature of 248 ± 25°F for the duration of the test program. The particulate filter holder was also kept at a temperature of 248 ± 25°F. The back-half condensable part of the train consisted of a condenser and water dropout followed by an empty impinger. After the empty impinger, a Teflon filter (CPM Filter) was placed prior to an impinger containing a 100 mls of water and the last impinger contained a known amount of silica gel. All impingers and the water dropout were weighed before and after each test to determine the moisture content of the gases. The condensor, knockout, empty impinger and CPM Filter were purged with nitrogen for one (1) hour at fourteen (14) liters per minute following each run. After the nitrogen purge, each of those components, 11 of 89 GP081AS-041316-RT-1661 Kilgore Companies, West Valley, UT Dillman 500 TPH Portable Counter-flow Hot Mix Asphalt Plant 2024 PM, PM10, and PM2.5 and VEs Compliance Test Report along with the back of the heated filter housing and the front half of the CPM filter were rinsed twice with water and the contents placed in a sample container labeled water rinse. Following the water rinse, each of the components were then rinsed once with acetone and then twice with hexane and the contents were placed in sample container labeled organic rinse. The water rinse and the organic rinse were evaporated and weighed and included to the total particulate catch. The CPM filter was also weighed to dryness before and after each run, and the weight was included in the total wash. The CPM filter was maintained at a temperature between 65°F and 85°F during each sample run. A binderless glass fiber filter was employed as the capture media for the particulate emissions. The probe, nozzle and pre-filter glassware was washed with AR grade acetone. The acetone was then evaporated and weighed. The acetone catch was added to the filter weight and used in the emissions calculation for particulate determinations. The acetone catch, filter weight and the back-half condensibles were be used to calculate PM10/PM2.5 emissions. The FPM, CPM, and total (TPM) results are reported in emission concentration and emission rate units. Pertinent information regarding the performance of the method is presented below: • The cross-over piece located between the filter and the probe was modified to receive a thermocouple to measure the temperature of the gases leaving the probe. • Condensed water is measured gravimetrically. • Target Sample Duration: 60 minutes. • Minimum Required Sample Volume: 31.8 dscf. • Alt-009 was used for the post-test dry gas meter calibration. The typical sampling system is detailed in Figure 3-1. 12 of 89 GP081AS-041316-RT-1661 Kilgore Companies, West Valley, UT Dillman 500 TPH Portable Counter-flow Hot Mix Asphalt Plant 2024 PM, PM10, and PM2.5 and VEs Compliance Test Report 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).
