1. Executive Summary
1.1 Introduction
U.S. Magnesium ("U.S. Mag") contracted Optimal Air Testing Services, lnc. ("Optimal" or
'OATS') to conduct air emissions testing at the U.S. Magnesium facility in Tooele County,
Utah. The objective of the test program was to accurately measure concentrations and
emissions of Nitrogen Oxides (NOx) and Carbon Monoxide (CO) from the Lithium Carbonate
Plant's 1,500 horsepower boiler.
Coordinating the field portion of the test program were Jeffrey Mensinger and Roger Francom
of U.S. Mag and Daniel Klassen of Optimal. No representative from the local regulatory
agency was present during the testing.
1.2 Summary of Test Program
The test program followed the procedures prescribed in Title 40 of the Code of Federal

2. Test Program Description
2.1 Test Method Description
2.1.1 Determination of Stack Points
40CFR60 Appendix A,1 was used to determine sample points for traverses
measuring velocity head temperature.
Velocity and temperature points were based on upstream and downstream
distances from flow d and the stack diameter according to Figure 1-1 as
presented in Section 4.2 ot report.
2.1.2 Determination of Stack Velocity
40CFR60 Appendix A,2 procedures were followed to calculate stack gas
velocity during each run.
The velocity and sampling apparatus consisted of calibrated
Stausscheibe (Type S)steel pitot tube and a thermocouple to measure gas
temperature. Velocity s were checked for leaks before and after each test
verified in field following the testing by following therun. The thermocouples
procedures in Method 2 10.3 orALT-011.

December 26,2023
2023 LITHIUM BOILER EMISSIONS
lnstrumental Reference Method procedures for determination of orygen (Oz) and
carbon dioxide (CO, concentrations were conducted utilizing a common sample
apparatus. The gas sample was extracted from the source at a constant rate through
a probe, filter, and sampling system at stack temperatures or heated to 250 oF until
introduction to a gas conditioning system for removal of moisture. The particulate
free and dry gas sample was then introduced to the analyzers.
The following gas analyzers were used for sample analysis:
The Calibration Error Test, or 3-point analyzer calibration error test, was performed
by introducing the zero and high level gases, and making adjustments, in Direct
Calibration Mode, the mid level gas was then introduced, without making
adjustments, to veriff linearity. The values achieved were validated by the Analyzer
Calibration Error, maintaining within two percent of the Calibration Span.
System Bias Checks were performed during the testing program to determine
analyzer bias and drift. The check is performed after every run. The analyzer biases
(pre and post run) were less than the allowable five percent difference from the direct
calibration values and the analyzer drift was less than the allowable three percent
from the pre-run calibration value for all runs. The pre/post-run bias check values
were used to calculate bias corrected numbers from the recorded data average for
analyzer bias and drift. EPA Traceability Protocol 1 calibration gases with known
concentrations were used for all calibrations.
A data acquisition system (DAS) was used to continuously record all gas
concentrations and integrate these values into minute intervals/averages. These
results were transferred to a spreadsheet where average values corrected for
calibration responses are reported.
2.1.4 Determination of Moisture Content
40CFR60 Appendix A, Method 4 procedures were followed to assemble the sampling
equipment and to calculate moisture content during each run.
A sample of the stack gas was drawn into impingers immersed in an ice bath to cool
the gas below 68oF, which condensed the moisture collected into the impingers. The
total weight gain of the impingers (condensate) and the measured volume of the gas
drawn through the impingers was used to calculate moisture concentration.
2.'1.5 Determination of Volumetric Flow Rate
Data collected from Methods 1-4 was used to determine the Volumetric Flow Rate.
2.1.6 Determination of Pollutant Concentrations
40CFR60 Appendix A, lnstrumental Reference Method procedures 7E (NOx) and 10
(CO) were followed for the determination of pollutant concentrations. The gas sample
was extracted using a common sampling apparatus as described above for the
diluent gases.
Report No. RPT 23USM-A -5of45-December 26,2023
2023 LITHIUM BOILER EMISSIONS
The continuous gas analyzers used for sample analysis consisted of the following:
The calibration procedures used were identical to those listed above for the diluent
gases.
2.1.7 Determination of Visible Emissions
40CFR60 Appendix A, Metlrod 9 was used to determine visible emissions. A trained
and certified observer recoded plume opacity from the sources. Method 9 quality
assurance guidelines for observer position, field records, observations, and data
reduction were followed. Opacity observations included 18O-minutes of observations
simultaneously with other testing.
2.1.8 Galculation of Mass Emission Factor and Volumetric Flow Rate
40CFR60 Appendix A, Method 19 procedures were followed to calculate emission
rates of constituents. The Method 19 dry fuel factor of 8,710 dscf/mmBTU, for Natural
Gas, was used in these calculations.
The dry fuelfactor along with the measured Oz content were utilized to calculate the
pounds per million btu (lb/mmBTU).
2.1.9 Verification of Gas Dilution System
40CFR51 Appendix M, Mdthod 205 procedures were followed to verify the gas
dilution system during the,testing project. Protocol gases were blended with a
certified and calibrated mdss flow gas divider to arrive at the desired calibration
concentrations for analyzer lcalibrations and quality assurance checks.
An Environics Model 4040 gas divider with three mass flow controllers was used to
blend nitrogen (Nz) and protocol gas mixtures for the desired calibration gas
concentrations. The mass flow controllers in the gas divider were calibrated prior to
testing, and the gas dividgr operation on-site was verified with the oxygen (Oz)
analyzer and an independent protocol Oz calibration gas.
The on-site verification was performed by entering two target concentrations into the
gas divider software. A higl1 range protocol Oz gas and the zero Nz gas were blended
with the mass flow controllers to meet the target concentrations introduced to the Oz
analyzer one at a time. Analyzer response was verified by introducing a mid-level
calibration gas directly into the analyzer. This process was repeated in triplicate. All
analyzer responses for the target concentrations and the verification gas did not
deviate more than two percent from the predicted concentrations or more than two
percent from the average instrument response for each concentration.
2.2 Deviations from Published Test lUethods and Testing Comments
No deviations from standard EPA air sampling methodologies were utilized during this testing
program. The procedures outlined in the testing protocolwere adhered to during this testing
program.
