1.0 Introduction
Alliance Technical Group, LLC (Alliance) was retained by Interstate Rock Products (Interstate) to conduct
compliance testing at the Hurricane, Utah facility. Portions of the facility are subject to provisions of DAQE-
AN110600003-23 and 40 CFR 60, Subpart I. Testing was conducted to determine the emission rate of particulate
matter (PM) at the exhaust of the Drum Mix Asphalt Plant Baghouse. Visible emissions evaluations (VEE) were
also conducted to determine the opacity of the Drum Mix Asphalt Plant Baghouse exhaust.
1.1 Facility Description
Interstate’s Hurricane facility is located at 42 South 850 West in Hurricane, Utah, where it manufactures asphaltic
concrete for paving applications. Facility operations include an active aggregate mine, crushing and screening plant,
and a hot mix asphalt plant with a drum mixer, conveyors, screens, augers, weigh hoppers, silos, and cold aggregate
bins. Engines provide electrical power to the plant.

The permit limits production of asphaltic concrete to 150,000 tons per any 12 consecutive-month period, of which
no more than 37,500 may be reclaimed asphalt pavement (RAP). The Approval Order also limits the fuel that can be
used in the hot mix asphalt plant to natural gas.

consisted of determining the emission rate of PM at the exhaust of the Drum Mix Asphalt Plant Baghouse. VEEs
were also conducted to determine the opacity of the Drum Mix Asphalt Plant Baghouse exhaust.

Table 2-1 provides a summary of the emission testing results with comparisons to the applicable UDAQ permit
limits. Any difference between the summary of results listed in the following table and the detailed results
contained in the appendices is due to rounding for presentation.

3.0 Testing Methodology
The emission testing program was conducted in accordance with the test methods listed in Table 3-1. Method
descriptions are provided below while quality assurance/quality control data is provided in Appendix D.

3.1 U.S. EPA Reference Test Methods 1 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 1. To determine the minimum number of traverse points, the upstream and downstream
distances were equated into equivalent diameters and compared to Figure 1-1 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.

The O2 and CO2 concentration were assumed to be ambient for molecular weight and volumetric flow rate
calculations.

Stack gas velocity pressure and temperature readings were recorded during each test run. The 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 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 quantity 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.
3.3 U.S. EPA Reference Test Methods 5 and 202 – Total Particulate Matter
The total particulate matter (filterable and condensable PM) testing was conducted in accordance with U.S. EPA
Reference Test Methods 5 and 202. The complete sampling system consisted of a silicon nozzle, glass-lined probe,
pre-weighed quartz filter, coil condenser, un-weighed Teflon filter, gas conditioning train, pump and calibrated dry
gas meter. The gas conditioning train consisted of a coiled condenser and four (4) chilled impingers. The first, and
second impingers were initially empty, the third contained 100 mL of de-ionized water and the last impinger
contained 200-300 grams of silica gel. The un-weighed 90 mm Teflon filter was placed between the second and
third impingers. The probe liner heating system was maintained at a temperature of 248 ±25°F, and the impinger

temperature was maintained at 68°F or less throughout testing. The temperature of the Teflon filter was maintained
greater than 65°F but less than or equal to 85°F.

Following the completion of each test run, the sampling train was leak checked at a vacuum pressure greater than or
equal to the highest vacuum pressure observed during the run. The nitrogen purge was omitted due to minimal
condensate collected in the dry impingers. After the leak check the impinger contents were measured for moisture
gain.

The pre-weighed quartz filter was carefully removed and placed in container 1. The probe, nozzle and front half of
the filter holder were rinsed three (3) times with acetone to remove any adhering particulate matter and these rinses
were recovered in container 2. All containers were sealed, labeled and liquid levels marked for transport to the
identified laboratory for filterable particulate matter analysis.

The contents of impingers 1 and 2 were recovered in container CPM Cont. #1. The back half of the filterable PM
filter holder, the coil condenser, impingers 1 and 2 and all connecting glassware were rinsed with DIUF water and
then rinsed with acetone, followed by hexane. The water rinses were added to container CPM Cont. #1 while the
solvent rinses were recovered in container CPM Cont. #2. The Teflon filter was removed from the filter holder and
placed in container CPM Cont. #3. The front half of the condensable PM filter holder was rinsed with DIUF water
and then with acetone, followed by hexane. The water rinse was added to container CPM Cont. #1 while the solvent
rinses were added to container CPM Cont. #2. All containers were sealed, labeled and liquid levels marked for
transport to the identified laboratory for condensable particulate matter analysis.
3.4 U.S. EPA Reference Test Method 9 – Visible Emissions Evaluations
The stack gas opacity was determined in accordance with U.S. EPA Reference Test Method 9. Visible emission
evaluations were conducted by a certified visible emissions evaluator. Opacity readings were recorded in 15-second
intervals during each of three (3) 60-minute evaluations.

Project Narrative
Analytical Method(s):Method 5 - Determination of Particulate Matter Emissions From Stationary Sources
Method 202 - Dry Impinger Method for Determining Condensable Particulate Matter
Emissions From Stationary Sources
Filterable The filter(s) were either oven dried and/or desiccated per the method until a final
weight was obtained. The liquid fractions were extracted if required, evaporated and
cooled until a final weight was obtained. These fractions were summed together to
provide the total Particulate Matter collected.
Condensable The filter(s) were extracted per the method. The organic extract was added to the
organic rinse, and the inorganic extract was added to the inorganic rinse. The
inorganic fraction was extracted with solvent per the method. Extracts were combined
with the organic rinse. The organic and inorganic fractions were evaporated and
desiccated until a final weight was obtained.
MDL The Minimum Detection Level (MDL)is 0.5 mg per fraction.If the measured result for a
fraction is less than the MDL, the MDL was used in ensuing calculations.
Blank Correction If blank correction is performed,only blank values returned higher than the MDL are
used.If a blank returns a value less than the MDL,no correction is included.Method 202
Recovery Blank corrections are applied by fraction (inorganic subtracted from
inorganic; organic subtracted from organic).
Custody:The samples were received by Eric Grosjean on 08/23/2024 at 07:52 in Arvada, CO. The
samples were received in good condition with proper Chain-of-Custody
documentation. No apparent container problems were noted upon receipt. Prior to
analysis, the samples were kept secure with access limited to authorized personnel of
AST.

Equipment:Mettler Toledo Balance ML-104, SN B217893065. This scale was used for analytical
determinations of filters and rinse vessels.
Denver Instruments Balance TB-6201, SN 17904189. This scale was used to measure the
total mass of rinse collected for blank correction.
Analysis was performed on the same balance as the associated tare.
Quincy Lab Inc oven, 30CG, SN G3-012673.
QC Notes:The samples met the minimum criteria established by the relevant method.
A blank correction was applied per the method.
Reporting Notes:M5/202-Asphalt Baghouse-Run 2 Cont. 5 was received leaking and the lid was
