Young University Main Campus in Utah County, UT. Testing will be performed the week of February 3,
2025, to determine compliance with the emission limits found in condition II.B.2.b of Approval Order
DAQE-AN107900021-23 and 40 CFR Part 60 Subpart Db.

PROTOCOL CONDITIONS:

1. RM 1 used to determine sample velocity traverses: OK
2. RM 2 used to determine stack gas velocity and volumetric flow rate: OK
3. RM 3A used to determine dry molecular weight of the gas stream: OK
4. RM 4 used to determine moisture content: OK
5. RM 7E used to determine NOx emissions: OK

DEVIATIONS: None.

CONCLUSION: The protocol appears to be acceptable.

RECOMMENDATION: The methods proposed in the pretest protocol are sufficient to
determine NOx emissions from Boiler #4 and Boiler #6. It is
recommended that the pretest protocol be determined as
acceptable.

Project Organization and Responsibility
The following personnel and the testing contractor are presently anticipated to be involved in the
testing program. Utah Department of Environmental Quality, Division of Air Quality (DAQ)
may have their own personnel or contractor to observe all phases including the process.

During these tests only Brigham Young University (BYU) personnel listed above or assigned
personnel from the operation are authorized to answer or obtain answers to pertinent questions on
the process conditions or the test protocol.
Test Schedule
It is planned to complete this test project January 9-11, 2023. The testing crew will arrive and set
up the test equipment January 9, 2023. It is anticipated that testing will begin the morning of
January 10th and continue until all testing has been completed. A pretest meeting may be held at
the request of BYU or DAQ.
Project Description
This test project will be conducted to comply with the requirements of BYU’s Approval Order,
DAQE-AN107900019-20, dated January 29, 2020, which requires testing Boilers #4 and #6 for
NOx emissions every three years. Testing will be performed according to EPA Methods 1-4, and
7E and will include accumulating process and production data.
Test Procedures
Three tests runs will be conducted on each unit for NOx emissions. Testing will be EPA
Methods 1-4 and 7E as specified in 40 CFR 60, Appendix A. One Method 4 test may span up to
three Method 7E test runs. Specific test procedures are as follows:
EPA Methods 1-4
1.Boilers #4 and #6 have a common exhaust duct with inside dimensions of 48 inches by 84
inches. The sample ports are located approximately 18.5 feet downstream and 6 feet
upstream from any flow disturbance and conform to EPA Method 1. Sample points will
be selected according to EPA Method 1 for a non-particulate traverse.
2.EPA Method 2 will be used to determine gas stream velocity. Type “S” pitot tubes will
be used with a Cp factor of 0.84. Dual inclined/vertical manometers with graduations in
0.01 inches of water will be used. If flows are below 0.05 inches of water a more
sensitive manometer will be used. The graduations marks on int are 0.005 inches of
water. Direction of gas flow will be checked for cyclonics prior to testing.
3.A barometer will be used to measure the barometric pressure. It is periodically checked
against a mercury barometer. Prior to testing it will be checked to assure an accurate
barometric pressure.
4.EPA Method 3, or 3A, will be used to determine the gas stream dry molecular weight.
For Method 3 an integrated flue gas sample would be taken from the exhaust line after the
dry gas meter orifice during each run and analyzed at the completion of the test with an
Orsat to determine the molecular weight of the effluent gas stream.
5.All Method 4 test run durations will be sufficient to sample at least 21 dscf as required by
Method 4.
6.The probe liners will be 316 stainless steel.
7.Preparation and clean-up by the contractor will be performed in the contractor's testing
trailer. Laboratory work and analysis will be performed by the testing contractor as soon
as possible after all tests have been completed.
8.If plant maintenance or operating problems arise during the test, the test may be stopped.
This determination will be made by the Brigham Young University representatives or
operating personnel in consultation with agency representatives.
2
9.Current calibration data is submitted in Appendix A of this protocol. Any equipment
calibration that fall past due prior to the test date will be recalibrated prior to use.
Gaseous Analyzer Measurements
The following procedures will be used fo the Method 7E tests:
1.A gaseous analyzer will be used to measure the NOx concentrations during the emissions
test project. It is planned to run the NOx machine on the 0-250 ppm range. EPA Protocol
1 gases will be used as calibration standards with dry nitrogen as a zero gas.
2.A gaseous analyzer may be used to measure the O2 and CO2 concentrations in place of an
Orsat analysis during the emissions test project. If operated, the O2 and CO2 analyzer
would be run on the 0-10, or 0-20, percent range. EPA Protocol 1 gases would be used
as calibration standards with dry nitrogen as a zero gas.
3.The gas analyzer sampling train will consist of the following: an in-stack glass fiber
filter, heated stainless steel probe, Teflon heated sampling line to the water removal
system, water removal system, Teflon transport lines, gas manifold, and out of stack
Teflon filter after the gas manifold but prior to analyzers. The sampling train is built such
that the sampled gas only comes in contact with inert materials, i.e., Teflon, stainless
steel, and glass.
4.The number of sample points for the Method 7E sampling train will be determined
according to the results of a stratification check as per Method 7E, section 8.1.2.
5 The NOx converter efficiency check will be completed according to Method 7E, section
16.2.2.
6.Bias checks, calibration drift, zero drift and calibration error will follow the specified
guidelines of EPA Method 7E. Interference responses were determined in the factory and
no alterations have been done, therefore, factory specifications are satisfactory.
7.A data logger will be used to record measured concentrations. Gas analyzer data during
port changes will not be considered valid data.
Test Area
The test area shall include the Heating Plant control room, main floor, and stack areas, and the
area around the contractors testing trailer.
3
Process Data
Process parameters are available via computer in the Heating Plant control room. Pertinent
process parameters will be made available to DAQ personnel and included in the test report.
Quality Assurance
All testing and analysis in these tests will be conducted according to Methods 4 and 7E as
specified in this protocol, and appropriate sections of the EPA Quality Assurance Handbook for
Air Pollution Measurement Systems Vol. III.
Reporting
Complete copies of raw data, calculations and summary of test will be included in reports. All
process and production data will be recorded and retained for inspection and copying by DAQ.
The contractor will furnish copies of the test report to Brian Harris, Environmental Manager,
BYU.

METHOD 5 DRY GAS METER CALIBRATION USING CRITICAL ORIFICES
1) Select three critical orifices to calibrate the dry gas meter which bracket the expected operating range.
2) Record barometric pressure before and after calibration procedure.
3) Run at tested vacuum (from Orifice Calibration Report), for a period of time
necessary to achieve a minimum total volume of 5 cubic feet.
4) Record data and information in the GREEN cells, YELLOW cells are calculated.

This cylinder was certified according to the 2012 EPA Traceability Protocol, Document #EPA-600/R-12/531, using Procedure G1. Uncertainty above is expressed as absolute expanded
uncertainty at a level ·°',confidence of approximately 95% with a coverage factor k = 2. Do Nbt Use this Standard if Pressure is less than 100 PSIG.
·CO2 responses have been corrected for Oxygen IR Broadening effect. 02 responses have been corrected for CO2 inter;ference.
