INTRODUCTION

Test Purpose

This test was conducted to determine the NOx emissions from Utah Municipal Power Agency’s
(UMPA), Provo facility, Caterpillar G3520H Engines 1 - 5. Emissions are expressed in parts per
million (ppm), grams per horsepower-hour (g/hp-hr), and pounds per hour (lb/hr). Results are
used to determine compliance with the facility’s Approval Order, DAQE-AN107950015-16.

Test Location, Type of Process

All testing was conducted at UMPA’s power generating facility located in Provo, Utah.

The five Caterpillar G3520H engines’ exhaust stacks were identical in configuration. A
schematic representation of the stacks is found in Appendix D as Figure 1.

Test Dates

Two runs were completed on Engine 5 January 9, 2024. The final run on Engine 5 and three runs
on Engine 4 were completed January 10, 2024. Engine two was tested January 11, 2024.
Engine 1 was tested January 12, 2024, and Engine 3 was completed January 16, 2024.

Pollutant Tested and Methods Applied

SOURCE OPERATION

Sampling Port Location

The inside diameters of the Caterpillar G3520H engines exhaust stacks were 21.75 inches. Port
location is depicted in Figure 1 in Appendix D. The ports were located 11.59 diameters (252
inches) downstream from the last disturbance and 7.45 diameters (162 inches) upstream from the
next disturbance. Two, two-inch diameter ports were available for testing on each stack. The port
reference measured 2.75 inches.

Sampling Point Location

Table II shows the distance of each sampling point for Method 4 from the inside wall. Each point
was marked with a glass tape wrapping and numbered. These points were determined by
measuring the distance from the inside wall and adding the reference (port) measurement. Table II. Sample Point Location Sample Point #
Point Location from Inside Wall (inches) 1 0.96 2 3.18 3 6.44 4 15.31 5 18.57 6 20.79
Sampling Train Description To determine the actual emission rates for these stacks 40 CFR Part 60 Appendix A, Methods 1-4 and 7E were followed. All sampling trains were made of inert materials (Teflon, stainless steel, and glass) to prevent interference of the sampled gas. The stack analyzer used to conduct Methods 1-4 was constructed to meet the specifications outlined in the CFR. The temperature sensors were K-type thermocouples. Heater, vacuum, and

5
pitot line connections were designed to be interchangeable with all units used by the tester. The probe liner was made of 316 stainless steel. A sampling train sketch is found as Figure 2 in Appendix E. Sample boxes were prepared for testing by following the prescribed procedure outlined in Method 4. The NOx analyzer was an Horiba VIA 510SS Chemiluminescence unit. The analyzer was spanned at 22.3 ppm for all tests. EPA Protocol 1 gases were used as the span and mid-range for the NOx analyzer during all tests; their concentrations were 11.2 and 22.3 ppm. Dry nitrogen was used as the zero gas for the machine. The CO2 /O2 dual gas analyzer was a CAI ZRE unit. The CO2 detector was nondispersive infared and the O2 detector was an electrochemical cell. The CO2 analyzer was spanned at 20.41 percent for all tests and calibrated with EPA Protocol 1 gases of 20.41 and 9.75 percent CO2. The O2 analyzer was spanned at 20.73 percent for all tests and calibrated with EPA Protocol 1 gases of 20.73 and 9.77 percent O2. Dry nitrogen was used as the zero gas for both gases. The sampling train for Method 7E was constructed with a heated stainless steel sampling probe about 3 feet long. The sample line between the sampling probe and gas conditioner was heated Teflon. Both were maintained above 220 degrees Fahrenheit. The sample conditioner used Peltier plates to remove moisture. Sample lines from the gas conditioner to the analyzer were Teflon. A sampling train sketch for this method appears as Figure 3 in Appendix E. Sampling and Analytical Procedures All test procedures employed were as specified in 40 CFR 60, Appendix A. Quality Assurance All equipment set-up, sampling procedures, sample recovery, and equipment calibrations were carried out according to the procedures specified in 40 CFR 60, Appendix A. and the Quality
Assurance Handbook for Air Pollution Measurement Systems.

Facility Location and Description

Utah Municipal Power Agency (UMPA) operates a power generating facility in Provo, Utah.
The plant operates five (5) Caterpillar G3520H 2547 kW natural gas-fired engines equipped with
a combination of SCR and oxidation catalyst to control emissions.

Test Objective

The purpose of this test project is to demonstrate compliance with the NOx emission limits for
the Caterpiller engines as required in the facilities Approval Order, DAQE-AN107950015-16,
section II.B.1.c.1 which requires testing of the engines once every three (3) years.

Test results will be reported in terms of grams per horsepower-hour (g/hp-hr) and/or pounds per
hour (lb/hr). Testing will be conducted according to the principals of EPA Methods 1-4, and 7E.

2

Test Schedule

It is planned to complete all testing the week of January 8, 2024. More than one engine may be
tested each day testing occurs.

If necessary, a pretest meeting may be scheduled by DAQ or UMPA.

Operational Data and Instrumentation

Each test will be conducted within 10 percent of 100 percent of the highest achievable load. The
kilowatts produced by each engine will be recorded at least once every 15 minutes during each
test run. Any additional, pertinent process data will be made available to DAQ personnel.

Test Procedures

Three test runs will be completed on each engine. The duration of each test run will be at least
60-minutes. Stack testing will be EPA Methods 1-4 and 7E as specified in 40 CFR 60, Appendix
A. Specific procedures are as follows:

EPA Methods 1-4

1. The configuration and dimensions of each stack are identical. The inside diameters are
21.75 inches. The sample ports are located 252 inches downstream and 162 inches
upstream from any flow disturbance and meet the requirements of EPA Method 1 for
undisturbed flow. The total number of sample points will be based on Method 1 for a
nonparticulate traverse.

2. EPA Method 2 will be used to determine the gas stream velocity. Type S pitot tubes will
be used with a Cp factor of 0.84. A dual inclined/vertical manometer with graduations of
0.01 inches of water will be used. If the measured pressure differential is below 0.05
inches of water a more sensitive manometer will be used with graduation marks of 0.005
inches of water. Previous testing has verified the absence of cyclonic flow and there have
not been any configurational changes to the ducting that would increase any cyclonic
flow; therefore, cyclonic flow measurement should not be required for this testing
project.

3. EPA Method 3 or 3A will be used to determine the gas stream dry molecular weight. For
Method 3, an integrated flue gas sample will be taken from the exhaust line after the dry
gas meter orifice during each test run and analyzed at the completion of the test with an
Orsat to determine the molecular weight of the effluent gas stream.

3
4. EPA Method 4 will be followed to determine the gas stream moisture content. The dry
gas meter (DGM) sample volume will be sufficient to sample at least 21 dscf per test run.

5. Probe liners will be 316 stainless steel.

6. The barometric pressure will be measured with a barometer which is periodically checked
against a mercury barometer. The barometer will be checked prior to testing to assure an
accurate barometric pressure.

7. Calibration data is provided with this protocol in the Appendix. Equipment calibrations
that fall past due prior to the test dates will be recalibrated prior to being used. Any
calibration not included with this protocol, such as new or additional equipment, will be
made available to DAQ representatives upon request.

8. If maintenance or operating problems arise during the test, the test may be stopped. This
determination will be made by UMPA representatives and operating personnel in
consultation with agency representatives.

9. Any necessary preparation and clean-up by the contractor will be performed in the
contractor's sampling trailer or a clean area on UMPA=s property. The laboratory work
and analysis will be done by the contractor as soon as possible after all tests have been
completed.

Gaseous Analyzer Measurements

A gaseous analyzer will be used to measure the NOx concentrations simultaneously with EPA
Methods 1-4. It is planned to run the NOx machine on the 0-25, or 0-50 ppm range. EPA
Protocol 1 gases will be used as calibration standards with dry nitrogen as a zero gas.

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. The average NOx ppm level
will be corrected according to equation 7E-5.

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 analyzer. The sampling train is built such that the sampled gas only contacts inert
materials, i.e., Teflon, stainless steel, and glass.

A data logger will be used to provide a recorded gas concentration measurement. Gas analyzer
data taken between port changes will be discarded; this allows for moving of the gas analyzer
probe to allow the flows and moisture test probe to have undisturbed access to all ports.

Test Area

The test area shall include the engine room, control room, stack and associated areas, and the
area around the contractor=s testing trailer for preparation and clean-up.

Quality Assurance

All testing and analysis in these compliance tests will be conducted according to Methods 1-4,
and 7E and appropriate sections of the EPA Quality Assurance Handbook for Air Pollution
Measurement Systems Volume III.

Reporting

Complete copies of raw data, calculations and summary of the test will be included in the test
report. All process and production data will be recorded and retained for inspection and copying
by DAQ. Preliminary verbal results will be reported to UMPA on site. The written reports will
be submitted to DAQ within 30 days following completion of the tests.
