1.0 Introduction
Alliance Technical Group, LLC (Alliance) was retained by Compass Minerals Ogden Inc. (Compass) to conduct
compliance testing at the Ogden, Utah facility. The facility is subject to provisions of the Title V Operating Permit
#5700001003. Testing was conducted to determine the emission rates of particulate matter (PM), particulate matter
less than 2.5 microns (PM2.5), and particulate matter less than 10 microns (PM10) from the exhaust of one (1)
scrubber designated as AH-513.

Due to stack diameter and/or entrained water limitations of AH-513, Methods 5 and 202 were conducted in lieu of
method 201A and 202. Particle sizing was conducted using scanning electron microscopy to determine PM10 and
PM2.5.
1.1 Process/Control System Descriptions
Compass operates a mineral recovery facility on the eastern shore of the south arm of the Great Salt Lake near
Ogden, Utah in Weber County. This facility produces sodium chloride (NaCl), sulfate of potash (SOP) (K2SO4),
and magnesium chloride (MgCl2). The process uses crystallized salts, including halite (sodium chloride) and a
mixed salt containing potassium sulfate and magnesium sulfate from solar evaporation ponds. The raw halite is
washed, wet-screened, dried, cooled, dry-screened, packages, and shipped. The mixed salt is washed, slurried,
thickened, crystallized, and converted to schoenite which is then filtered, dried, screened, half granulated/compacted
and shipped as sulfate of potash.

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.

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 3/3A – Oxygen/Carbon Dioxide
The oxygen (O2) and carbon dioxide (CO2) testing was conducted in accordance with U.S. EPA Reference Test
Method 3/3A. One (1) integrated Tedlar bag sample was collected during each test run. The bag samples were
analyzed on site with a gas analyzer. The remaining stack gas constituent was assumed to be nitrogen for the stack
gas molecular weight determination. The quality control measures are described in Section 3.5.
3.3 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.
3.4 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 stainless-steel 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 five (5) chilled impingers.
The first, second and third impingers were initially empty, the fourth 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. Condensate was collected in the first dry impinger,
therefore the front-half of the sample train (the nozzle, probe, and heated pre-weighed filter) was removed in order
to purge the back-half of the sample train (coil condenser, first and second impingers and CPM filter). A glass
bubbler was inserted into the first impinger. If needed, de-ionized ultra-filtered (DIUF) water was added to the first
impinger to raise the water level above the bubbler, then the coil condenser was replaced. Zero nitrogen was
connected to the condenser, and a 90-minute purge at 14 liters per minute was conducted. After the completion of
the nitrogen purge 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) and six (6) 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.
3.5 Quality Assurance/Quality Control – U.S. EPA Reference Test Method 3/3A
Cylinder calibration gases used met EPA Protocol 1 (+/- 2%) standards. Copies of all calibration gas certificates can
be found in the Quality Assurance/Quality Control Appendix.

Low-Level gas was introduced directly to the analyzer. After adjusting the analyzer to the Low-Level gas
concentration and once the analyzer reading was stable, the analyzer value was recorded. This process was repeated
for the High-Level gas. For the Calibration Error Test, Low, Mid, and High-Level calibration gases were
sequentially introduced directly to the analyzer. All values were within 2.0 percent of the Calibration Span or 0.5%
absolute difference.

At the completion of testing, the data was also saved to the Alliance server. All data was reviewed by the Field
Team Leader before leaving the facility. Once arriving at Alliance’s office, all written and electronic data was
relinquished to the report coordinator and then a final review was performed by the Project Manager.

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 Ryan Gillett on 2/22/24 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.
Number of Samples:23 (2 on Hold)
Labeling: Acceptable
Analyst:Jake Schmitt - Laboratory Analyst I
Eric Grosjean - Technical Director
Equipment:Mettler Toledo Balance ML-104, SN B217893065. This scale was used for analytical
determinations of filters and rinse vessels.

This is to certify the gases referenced have been calibrated/tested, and verified to meet the defined specifications. This
calibration/test was performed using Gases or Scales that are traceable through National Institute of Standards and
Technology (NIST) to the International System of Units (SI). The basis of compliance stated is a comparison of the
measurement parameters to the specified or required calibration/testing process. The expanded uncertainties use a coverage
factor of k=2 to approximate the 95% confidence level of the measurement, unless otherwise noted. This calibration certificate
applies only to the item described and shall not be reproduced other than in full, without written approval from Red Ball
Technical Gas Services. If not included, the uncertainty of calibrations are available upon request and were taken into account
when determining pass or fail.
