Dear Mr. Burge,
Holcim (US) lnc. ("Holcim") owns and operates a Portland cement manufacturing plant located
in Morgan, UT. The Devil's Slide Plant operates under Utah Division of Air Quality issued Title V
Permit, No. 2900001004. The Plant is subject to the National Emission Standards for
Hazardous Air Pollutants for the Portland Cement lndustry ("Portland Cement NESHAP"), 40
C.F.R. Part 63, Subpart LLL and is a major source of HAPs.
Holcim is submitting this notification of performance and RATA testing of a newly acquired
Fridas24 Flame-ionization detector THC analyzer that is anticipated to be installed on or around
October 3'd. Our former FlD14 THC analyzer had ongoing issues associated with the main
board and permanent replacement was determined to be necessary in order to mitigate
downtime.
Holcim will immediately complete a Cylinder Gas Audit (CGA) and a 7-day drift test of the new
THC analyzer to verify accuracy. With this notification Holcim is scheduling RATA testing on
November 19-20, 2024. This provides for the 45-day advance notification required under R307-
170-7(2). Holcim remains open to accelerating the RATA testing if required or advised by the
Division. The purpose of this RATA is to demonstrate compliance with the test methods and
procedures in 40 CFR 63.1349, R307-170, and 40 CFR 63.7. (40 CFR 63.13a8(a)) for THC.

5. The reference method tests will be conducted so that they will yield results representative
of the pollution concentration and emission rate from each unit and can be correlated with
the measurements from the continuous Oz and THC monitoring systems. To properly
correlate individualCEM pollutant values with the reference method data (e.9., THC ppm,
etc.) the beginning and end of each reference method test run wil! be marked to include
the exact time of day on the data acquisition system. The expected anallzer range is 0-
20o/ofor Oz and 0-50 ppm for THC.

6.0 TEST METHODOLOGY
Emission testing will be conducted following the methods specified in 40CFR60, Appendix A.
Schematics of the sampling trains and data sheets to be used are appended.
The following methodologies will be performed during the test program:
6.1 Method 1 Sample and Velocity Traverse Determination
Test measurement points are selected in accordance with Method 1, 40 CFR, Part 60, Appendix
A. The characteristic of the measurement location is summarized below.
6.2 Method 3A Oxygen (Oz) Determination
An oxygen (Oz) analyzer will be used to determine Oz concentrations in the stack gas in
accordance with Method 3A, 40CFR60. This instrument has a paramagnetic detector and
operates in the nominal range of 0o/o to 25o/o Oz. High-range calibrations will be performed using
Protocol One gas. Zero nitrogen (a low ppm pollutant in balance nitrogen calibration gases) wi!!
be introduced during other instrument calibrations to check instrument zero. High- and a mid-
range o/o Oz levels in balance nitrogen will also be introduced. Zero and mid-range calibrations
will be performed using USEPA Protocol gas after each test run.
6.3 Method 4 Moisture (HzO) Determination
Stack gas moisture content will be determined using a Method 4 sampling train. ln this technique,
stack gas is drawn through a series of four impingers. The first two impingers are each charged
with 100 mls of deionized, distilled water. lmpingerthree is left empty and impingerfour is charged
with clean, dried silica gel. The entire impinger train is measured or weighed before and after
each test run to determine the mass of moisture condensed.
During testing, the sample train will be operated in the manner specified in USEPA Method 4. All
of the data specified in Method 4 (gas volume, delta H, impinger outlet welltemperature, etc.)will
be recorded on field data sheets.
All of the equipment used is calibrated in accordance with the specifications of the Method.
Calibration data will be appended to the final report.

6.4 Method 25A THC Determination
The Method 25A sampling and measurement system meets the requirements for stack sampling
of THC set forth by the United States Environmental Protection Agency (USEPA). ln particular, it
meets the requirements of USEPA Reference Method 25A, "Determination of Total Gaseous
Organic Concentration Using a Flame lonization Analyzer," 40CFR60, Appendix A. This method
applies to the measurement of total gaseous organic concentration of hydrocarbons. With this
method, gas samples are extracted from the sample locations through heated Teflon sample lines
to the analyzers.
The flame ionization detectors (FlDs) to be used during this program are Thermo 51 Series Total
Hydrocarbon Analyzers. They are highly sensitive FlDs that provide a direct reading of total
organic vapor concentrations with linear ranges of 0-10, 100, 1000, and 10,000 ppm by volume.
The instruments are calibrated using ultra-zero air and propane in air EPA Protocol standards.
The calibrations are performed before and after sampling with calibration checks performed
between each test run. Final concentrations will be reported in ppm volume, dry as propane.
Calculations are performed by computer or by hand. An explanation of the nomenclature and
calculations along with the complete test results is included in the appendix. Also appended are
calibration data and copies of the raw field data sheets.
7.0 QUALITY ASSURANCE PROCEDURES
Mostardi Platt recognizes the previously described reference methods to be very technique
oriented and attempts to minimize all factors that can increase error by implementing its Quality
Assurance Program into every segment of its testing activities.
Copies of all pertinent calibration data (calibration gas certifications, Pitot tubes, dry gas meters,
nozzles, etc.) will be given to the on-site observer from the observing agency prior to testing and
included in the finaltest report.
Calculations are performed by computer. An explanation of the nomenclature and calculations
along with the complete test results wi!! be appended in the fina! report. Calibration data and
copies of the raw field data sheets will also be appended. Analyzer interference data is kept on
file at Mostardi Platt.
All the data necessary for the agency to reproduce the reported results will be included in the fina!
test report. The data shall include, but not be limited to DAS printouts, unit operationa! data (e.9.,
steam flow, etc.) calibration data, uncorrected run averages, raw lab analysis (including
chromatograms, spectra or other instrument output, and calibration and OA/QC data) with
summary tables, and raw field data.
Dry gas meters are calibrated according to methods described in the Code of Federa!
Regulations. The dry test meters measure the test sample volumes to within 2 percent at the
flowrate and conditions encountered during sampling.
