1.1 Introduction
An air emissions test program was conducted on a Caterpillar G3516B engine, operated by
Ovintiv USA Incorporated and designated as Unit #6 (14338), located at the Ranch
Compressor Station in Duchesne County, Utah. The purpose of the testing was to
demonstrate ongoing compliance with the emissions limits contained in UDEQ Permit
# DAQE-AN143380009-24 and EPA 40 CFR 60, Subpart JJJJ, for oxides of nitrogen (NOx),
carbon monoxide (CO) and volatile organic compounds (VOC) defined as non-methane, non-
ethane hydrocarbons, reported as propane (NMNEHC C3).
The facility is located on tribal land, in Duchesne County, Utah.
Latitude: 40.13082 Longitude: -110.29638
Three one hour test runs were performed on December 10, 2024 to analyze NOx, CO and
VOC emission levels. Test runs were performed according to methodologies outlined by EPA
40 CFR 60(A) Methods 1-3 & EPA 40 CFR 63(A), Method 320. Each one hour test run
consisted of 60 readings taken at one minute intervals.
Process parameters were recorded during each test run in order to determine the load.
Parameters include the engine panel load percent reading.
The following key personnel were present during testing:

2.1 Stack Sampling Location
The facility is located on tribal land, in Duchesne County, Utah.
Latitude: 40.13082 Longitude: -110.29638
Testing was conducted on the Caterpillar G3516B engine. The sampling port for moisture,
NOx, CO and VOC measurements was approximately 2.5 pipe diameters (30”) downstream
from the nearest flow disturbance (Distance B) and 33.3 pipe diameters (400”) upstream from
the nearest disturbance (Distance A), as seen in Figure 1. The stack sampling location was
placed at approximately 50% insertion depth based on an O2 stratification check which
demonstrated a non-stratified flow regime. The stratification was conducted according to
EPA 40 CFR 75(A), §6.5.6.1 using 3 traverse points determined according to Table 1 below.

3.1 Discussion of NOx, CO and VOC Test Results
Three, one hour test runs were performed on December 10, 2024 to analyze exhaust NOx, CO
and VOC (NMNEHC C3) emission levels to demonstrate ongoing compliance with the
emissions limits contained in the UDEQ Permit # DAQE-AN143380009-24 and EPA 40
CFR 60, Subpart JJJJ. Testing for NOx, CO and VOC were run concurrently with one
another. Each test was performed at the maximum achievable load. Measured emissions were
below permitted limits. Please refer to the Appendices for a listing of all raw data, calibration
error response and calculations performed per EPA 40 CFR 60(A) requirements.
3.1.1 Source Test 1: Caterpillar G3516B, NOx, CO and VOC
The first test was performed from 10:08 to 11:07 for NOx, CO and VOC.
Based on operating parameters recorded during testing, the load was approximated at
979.8 bhp, and the average NOx and CO levels were found to be 0.52 lbs/hr and 0.07
lbs/hr respectively, below limitations. The VOC level tested at 0.35 lbs/hr, which
tested in compliance.
3.1.2 Source Test 2: Caterpillar G3516B, NOx, CO and VOC
The second test was performed from 11:09 to 12:08 for NOx, CO and VOC.
Based on operating parameters recorded during testing, the load was approximated at
979.8 bhp, and the average NOx and CO levels were found to be 0.53 lbs/hr and 0.06
lbs/hr respectively, below limitations. The VOC level tested at 0.35 lbs/hr, which
tested in compliance.
3.1.3 Source Test 3: Caterpillar G3516B, NOx, CO and VOC
The third test was performed from 12:10 to 13:09 for NOx, CO and VOC.
Based on operating parameters recorded during testing, the load was approximated at
966.0 bhp, and the average NOx and CO levels were found to be 0.52 lbs/hr and 0.06
lbs/hr respectively, below limitations. The VOC level tested at 0.35 lbs/hr, which
tested in compliance.

4.2 Equipment Utilization
The following equipment was used during the tests performed at this facility in conjunction
with procedures outlined by EPA 40 CFR 60(A) Methods 1-3 & EPA 40 CFR 63(A), Method
320.
• (1) MKS MultiGas 2030 FTIR Continuous Gas Analyzer (0.210 L/min sample flow, 0.014
atmosphere sample pressure, 1 atmosphere cell pressure, 191°C cell temperature)
• (1) Laptop Computer for the FTIR Analyzer using MKS MG2000 Software
• (1) 75ft or 100ft Heated Teflon Line w/ Heated Sample Probe and Spike Bypass Line
• S-Type Pitot Tube c/w 20 ft. Heated Sample Line (coefficient 0.84)
• (1) Fyrite O2/CO2 Analyzer
• (5) EPA Protocol G1 Calibration Gas (NOx, CO, C3H8, C2H4 and NO2)
The MKS Multigas 2030 FTIR Analyzer operated with a spectral resolution of 0.5 cm-1 and a
scan time of 30 seconds. The FTIR spectrometer utilizes a multi-pass gas cell with a 5.11
meter effective pathlength.
Figure 2 - Sampling Train Schematic-Method 320
Table 4 - Concentrations and Interference
The MKS 2030 software provides a Natural Gas Method that is designed to minimize all
expected interferences by removing the regions in the quant region where they are most
7
absorbed (i.e. picket fence approach). So, for example, all the water peaks that are greater
than about 0.1 abs are removed from the quant region. Since the spectral noise measured
(sample spectrum) is in the range of 0.001 absorbance, it is desirable to have any error within
this range. The MKS software will match the water calibration spectrum to the sample
spectrum at any 1 point in the spectrum to about 1% precision. So, 1% of 0.1 absorbance is
0.001 abs. This is why any peaks greater than this for interfering compounds are usually
excluded so they do not interfere. To summarize, the MKS software and the method are
designed to minimize any interferences by removing their largest interfering absorptions.
4.3 Measurement of VOC (NMNEHC C3)
The algorithm currently used for NMNEHC C3 and developed for natural gas fired
applications by Dr. Spartz and MKS instruments in accordance with EPA standards, is the
following:
(2.4*c8/(1+exp((2-c8)/0.2))+1.9*c11/(1+exp((2-c11)/0.2))+6*c12/(1+exp((0.5-c12)
/0.2))+2.85*c13/(1+exp((2-c13)/0.2))+3*c14/(1+exp((1-c14)/0.2)))/3
c8= acetylene
c11= ethylene
c12= hexane
c13= propylene
c14= propane
Note: The constants in front of each of the compounds listed represents the FID response
factor when calibrated with Propane.
As with any CEMS analyzer, the FTIR may demonstrate a negative zero bias. The “exp”
functions listed in the algorithm above are intended to mathematically filter out any negative
biases and set them to approach zero.
4.4 Process Parameters
The engine operating parameters were used in order to determine the load. Parameters
include the engine panel load percent reading. Results are provided in Appendix C.

5.1 Quality Assurance
The MKS Multigas 2030 FTIR Analyzer was used to measure NOx, CO and VOC on a dry
basis. A pre Direct and System calibration measurement was made on compounds of NOx,
CO, C3H8 and C2H4. In addition, post System calibrations were made on compounds of NOx,
CO, C3H8 and C2H4. Compounds of CO2 and C3H8 were measured for the quality assurance
spiking requirements. Levels for calibrations and zeroes must be within +/- 5% of the
certified calibration gas or response to zero gas, respectively.
CTS procedures were followed according to EPA requirements for both pre and post testing.
Similarly, QA spiking procedures were followed. Analysis of the CO2 exhaust effluent was
used to determine the dilution factor. Steady levels of the CO2 were observed and a sufficient
duration of time was allowed to elapse for a representative average.
The calibration gas was spiked into the effluent stream using a bypass line at approximately
10% of the sampling rate. The dilution factor was obtained from observation of the stack CO2
behavior using the following equation:
CO2AVG – CO2SPIKE
DF = ------------------------
CO2 AVG
Where:CO2AVG = The average undiluted CO2 stack gas concentration of spike measurements
CO2SPIKE = The average diluted CO2 stack gas concentration when spiked
The sample recovery was then obtained from the following equation:
% REC = (Spike MEAS – Stack MEAS)* (1 – DF)
---------------------------------------------------------
CS * DF
Where:Spike MEAS = The average diluted stack gas concentration when spiked
Stack MEAS = The average undiluted stack gas concentration
DF = Dilution factor
CS = Certified concentration of calibration standards
The Sample Recovery average level for C3H8 was found to be 79.0%, which was within the
allowable tolerance of Method 320 (70% to 130%). A summary of all spiking
procedures/results can be found in Appendix B.
