"SUBPART 'ZZZZ' EMISSIONS TESTING FOR CARBON MONOXIDE
(CO) REDUCTION ON ALLEN GRAVEL'S CATERPILLAR (3412) 725
KW ENGINE/GENERATOR LOCATED AT THEIR
FACILITY IN COVE, UTAH"
1.0 Introduction
1.1 Test Purpose
At the request of Allen Gravel's, Mr. Troy Allen, Montrose Air Quality Services, LLC.,
{MAQS) conducted testing for carbon monoxide {CO) at the inlet to the oxidation catalyst
and at the exit of the oxidation catalyst to verify a 70% reduction of CO emissions on one
(1) Caterpillar 725 KW Engine/Generator at their facility in Cove, Utah.
The Utah Department of Environmental Quality {UDEQ) issued Allen Gravel LLC. Intent
To Approve {ITA) {DAQE-IN119950003-23) on May 21, 2023. A copy of this ITA is
included in Appendix "A".
The Environmental Protection Agency {EPA) has implemented a National Emissions
Standards for Hazardous Air Pollutants (NESHAP) for Stationary Reciprocating Internal
Combustion Engines {40CFR, Part 60, Subpart "ZZZZ"). This requires that a catalyst be
installed on the engine/generator exhaust and CO emissions be measured before and
after the catalyst with at least a 70% reduction.
To satisfy the testing requirements, Allen Gravel requested that MAQS prepare a "Pretest
Protocol" to be submitted to the Utah Department of Environmental Quality. This Pretest
Protocol is presented in Appendix "B".
MAQS performed emissions testing as set forth in the Code of Federal Regulations
(CFR), Title 40 , Chapter I, Part 60, Appendix "A". The following methods were used to
evaluate the emissions testing:
Method 3A -"Gas Analysis for Carbon Dioxide, Oxygen, Excess Air and Dry
Molecular Weight" (Instrumental Analyzer Procedure)
Method 1 O -"Determination of Carbon Monoxide Emissions from Stationary
Sources"
2.0 Summary of Results
2.1 CO Emissions (EPA 10)
The emissions data accumulated for CO during the March 5, 2024 testing is summarized
in Table 2 .1.1 for the Inlet and Table 2.1.2 for the Outlet, for the Caterpillar 725 KW
Engine/Generator.

The average CO emission concentration corrected to 15% 02 for the Outlet was 9.92
ppm and the Inlet was 399 .18 ppm. This is below the 23 ppmvd@ 15% 02 and shows a
97.5% reduction of CO across the catalyst.
The CO (ppm) value is the concentration taken from the analyzer, while the CO (ppm
corrected) value is the concentrations after it has been corrected for bias and drift
calibration values. This corrected concentration is the value from which the mass
emissions are calculated.
3.0 Source Operation
3.1 General Plant Operations
Diesel oxidation catalysts (DOC's) are exhaust after-treatment devices that reduce
emission from diesel engines. Typically packaged with the engine muffler, DOC's are
widely used as a retrofit technology because they require little or no maintenance.
DOCs consist of a flow-through honeycomb structure that is coated with a precious metal
catalyst and surrounded by a stainless steel housing. As hot diesel exhaust flows through
the honeycomb (or substrate), the precious metal coating causes a catalytic reaction that
breaks down the pollutants. These devices may be formulated to operate with fuel sulfur
levels of 500 ppm or less, but they are most effective when fuel sulfur is 15 ppm or less.
DOCs can be coupled with closed crankcase ventilation, selective catalytic reduction or
lean NOx catalyst technologies for additional emission reductions.
The Caterpillar 725 KW Engine/Generator is used to create power to run a crushing
spread. This unit is variable output and changes for the demands of the crushing spread.
The engine has been closely monitored to acquire data relating to performance,
reliability, component performance and emissions levels.
The catalyst pressure drop and inlet temperature to the catalyst are shown at the tops of
the actual emissions data sheets and are shown in Appendix "C ".

4.0 Sampling and Analysis Procedures
4.1
A
Emissions Testing
EPA Method 3A; for gas analysis of carbon dioxide, oxygen, excess air, and dry
molecular weight.
This reference method requires that a gas sample be extracted from the stack for
analysis concurrently with each moisture run. The continuous gas sample is then
analyzed via a California Analytical analyzer for carbon monoxide, carbon dioxide
and oxygen. The nitrogen values are obtained by difference from 100% and the
cumulative CO, CO2 and 02 percentages. The Inlet and Outlet testing location
are shown in Figure 4.1.1.

CAT Engine/Generator
Figure 4.1.1: Caterpillar 725 ~ Engine/Generator
B. EPA Method 1 O; for gaseous emissions from Stationary Sources (Instrumental
Analyzer Procedures).
The sample train used to extract and condition the stack gases for analysis is
shown in Figure 4.1.2. A TECO Model 48i analyzer was used to measure CO
concentrations on the Inlet to the catalyst and a separate TECO Model 48i
analyzer was used on the Outlet. Readings were taken every minute for 60
minutes for three separate runs. These readings are included in Appendix "C".

Specific items used in the EPA approved sample trains require pretest and post-test
calibrations. The frequency of the calibrations and guidelines for procedural items are
delineated in the EPA's "Quality Assurance Handbook for Air Pollution Measurement
Systems".
For EPA Method 10, the quality assurance guidelines are intended to insure that the
gaseous emissions are quantified in a manner consistent with the most stringent
sampling criteria possible. MAQS testing personnel are thoroughly trained in all aspects
of the EPA required QA/QC guidelines . The crew supervisors have certified at the front of
this report that the test crew adhered to those guidelines in the regulations applicable to
compliance testing at Sunroc Corporation.

SOURCE INFORMATION
General Description
Allen Gravel LLC (AG) operates an aggregate pit in Cove, Cache County. Aggregate is harvested by
bulldozers or front-end loaders from the pit. Front-end loaders collect and take the aggregate to the
crushing/screening area of the pit. Crushers, dry screens, and wash (wet) screens process the aggregate.
The sized aggregate is stored on site. Sized aggregate and unprocessed aggregate are loaded into trucks
and taken to customers off-site. The plant will produce up to 600,000 tons of sized aggregate and
200,000 tons of unprocessed aggregate per year.

Project Description
AG has requested a modification to AO DAQE-AN0 119950002-l 0, dated F ebruary 18 , 20 I 0, t o add a
wash plant and make other equipment changes. The wash plant will consist of two washers, two wet
screens, sand screws, and various conveyor and stackers. The other equipment changes to the permit
include refurbishing the generator engine and adding a catalytic converter to it; replacing a three-deck
(dry) screen with a two-deck (dry) screen; and removing the 250-gallon gasoline storage tank and the
6,000-gallon diesel fuel storage ta nk. These two fuel storage tanks were never installed. Instead of thes e
two fuel storage tanks AG uses a 1,300-gallon diesel fuel storage tank and an 800-gallon diesel fuel
storage tank. The 1,300-gallon diesel fuel storage tank is attached underneath a refer trailer. The 800-
gallon diesel fuel storage tank is attached to a lubrication truck. Each one of these diesel fuel storage
tanks are on wheels and are therefore, mobile sources according to Title 2 of the Clean Air Act.
Therefore, because these storage t anks are considered mobile sources they are not included in the
stationary source permit issued by the Division of Air Quality.
SUMMARY OF EMISSIONS
The emissions listed below are an estimate of the total potential emissions from the source. Some
rounding of emissions is possible.

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 5-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 02, 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 mol;cular weight of
the gas stream, and the measured moisture.
Pertinent information regarding the performance of the method is presented below:
• Method Options:
o 5-type pitot tube coefficient is 0.84
o Shortridge multimeter may be used to measure velocity
o A dry molecular weight of 29.0 lb/lb-mole may be used to calculate gas
volumetric flow rate for sources that emit essentially air
The sampling apparatus is detailed in Figure 3-1.

Document No: GP081AS-037020-RT-1556
3.1.3 EPA Methods 3/3A, Gas Analysis for the Determination of Dry
Molecular WeightProcedures found in EPA Methods 3 and 3A may be used to
calculate the dry molecular weight of the stack gas using multi-point, integrated
sampling. The integrated gas sample bag is analyzed for percent CO2 and percent
02 using a calibrated paramagnetic 02 analyzer and a calibrated infrared CO2
analyzer.
3.1.4 EPA Method 4, Determination of Moisture Content in Stack
GasEPA 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 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 calculati o"h s
o Minimum Required Sample Volume: 21 scf.
The typical sampling system is detailed in Figure 3-1.
3.1.5 EPA Methods 3A, and 10, Determination of Oxygen, Carbon
Dioxide and Carbon Monoxide Concentrations in Emissions
from Stationary Sources (Instrumental Analyzer Procedures)
Concentrations of 02, CO2, and CO are measured simultaneously using EPA
Methods 3A and 10, which are instrumental test methods. Conditioned gas is sent
to a series of analyzers to measure the gaseous emission concentrations. The
performance requirements of the method must be met to validate the data.
Pertinent information regarding the performance of the method is presented below:
• A dry extractive sampling system may be used to report emissions on a dry
basis.
• Sampling may be performed using a dilution probe.
• A paramagnetic analyzer is used to measure 02.
• A nondispersive infrared analyzer is used to measure CO2.
• A gas filter correlation nondispersive infrared analyzer is used to measure CO ..
• Minimum Required Sample Duration: 60 minutes.

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.
