MountainWest Pipeline, LLC and designated as Unit T-1, located at the Blind Canyon
Compressor Station in Duchesne County, Utah. The purpose of the testing was to
demonstrate ongoing compliance with the emissions limits contained in Approval Order
#DAQE-AN130790006-12 and NSPS Subpart KKKK, for oxides of nitrogen (NOx) and
carbon monoxide (CO).
The Blind Canyon Compressor Station is utilized to boost the line pressure to accommodate
additional gas flow through the pipeline. The natural gas enters the station through a valve on
the main pipeline and flows through various filters and vortex separators to remove liquids
and other impurities (slugs) prior to compression. The filtered and separated impurities from
the pipeline are pumped to one of the on-site condensate storage tanks. After filtering, the
natural gas flows to the compressor engines where it is compressed to increase the pressure of
the gas. The temperature of the gas also increases upon compression. Therefore, after
compression the gas flows through an after cooler to be cooled to pipeline temperate prior to
being reintroduced to the main pipeline. Natural gas from the main pipeline is used to power
the on-site compressors and generators. The generators provide power for the facility and as
such, are not considered emergency backup generators.
Three, one hour test runs were performed on July 17, 2024 to analyze exhaust NOx and CO
emission levels in accordance with the procedures of 40 CFR 60(A) Methods 1, 3A, 7E, 10
and 19 and Subpart KKKK, as outlined in the submitted Source Test Protocol dated May 29,
2024. 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 and fuel
characteristics. Parameters include turbine gas producer speed, temperatures, and fuel gas
analysis.
The following key personnel were present during testing:

2.1 Stack Sampling Location
Sampling was conducted on the Solar Centaur 50 turbine (Unit T-1, SN OHE20-H9586). The
sampling ports for NOx and CO measurements were approximately 120.0" (3.3 pipe
diameters) downstream from the nearest flow disturbance (Distance B) and 37.0" (1.0 pipe
diameters) 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 12 traverse points determined
according to Table 1 below.

4.3 Process Parameters

Operating parameters recorded during testing were used in conjunction with a Solar program
to approximate the turbine load. Parameters include turbine gas producer speed and
temperatures. This was conducted and provided by MountainWest personnel. The supplied
fuel gas analysis was used to determine the Fd factor. Results are provided in Appendix C.

5.1 Quality Assurance

Precautions are taken to keep the gas analyzer in a clean, thermally stable, vibration free
environment to minimize analyzer drift and associated errors. Pre test calibrations and
most post test operations are performed within the testing trailer environment.

The data from the samples are converted directly into computer language and recorded in the
Compliance Specialist’s laptop computer. This eliminates the need for sample labeling and
secures the preservation of the data while reducing human error. In addition, parameters
associated with the turbine are recorded on test sheets at the time of the tests.

Preventive diagnostic functions are built directly into the equipment utilized for the testing.
This diagnostic function provides the Compliance Specialist with failure warnings allowing
the determination of when repairs are necessary without performing painstaking preventative
maintenance procedures. However, equipment is inspected regularly by the compliance
specialists and the Field Operations Manager to guarantee maximum operational status. The
process involved with equipment calibration ensures that there is no divergence from the
manufacturer’s specifications.

All pre and post calibration error checks, leak checks, and other quality assurance issues
conformed with the requirements specified in EPA 40 CFR 60(A), Methods 1, 3A, 7E, 10
and 19 and Subpart KKKK.

Linearity checks are performed using NOx, CO, O2 and Ultra High Purity Nitrogen certified
calibration gases to ensure that the zero, mid, and upscale calibrations are within the required
+/-2% of the certified calibration level and zero. Pre-Test calibrations are then conducted on
the zero and selected mid or upscale calibration gas determined by observing the native
concentration of the target analytes in the sampled exhaust. After each test run the same zero
and selected mid or upscale calibration gas are analyzed to verify they are within required
specifications. Calibration Error for post-test calibrations must remain within +/- 5% of the
certified calibration gas or zero. Drift is required to stay within +/- 3% during post-test
calibrations.

The following is a step-by-step calculation for the first test run conducted on the Blind Canyon
Compressor Station T-1.

Test Parameters
 Average O2 = 15.7%  Turbine Load = 3511.0 bhp
EPA Method 19: Determination of Stack Gas Flow Rate
Volumetric Flow Rate At Outlet (dscfm) = q * Fd * 1E-6 * HHV * 20.9 / (20.9 - O2)
Where:
q – Fuel flow = 590.2 scf/min Fd – Fuel factor (dry) = 8630.5 dscf/mmBtu HHV – Higher Heating Value of fuel = 1060.84 Btu/scf
O2 – Oxygen content in exhaust (%) = 15.7% 1E-6 – Conversion from Btu to mmBtu

= q * Fd * 1E-6 * HHV * 20.9 / (20.9 - O2)
= 590.2 * 8630.5 * 1E-6 * 1060.84 * 20.9 / (20.9 - 15.7)

= 21578.5 dscfm

EPA Method 7E and 10: Determination of NOx and CO Emissions From Stationary Sources Corrected Flue Gas Concentration (PPM) = (CR - CO) * CMa / (CM – CO)
Where:
CR – Average flue gas concentration indicated by gas analyzer (ppm) CO – Average of initial and final zero system bias checks (ppm)
CM – Average of initial and final span system bias checks (ppm)
CMa – Actual concentration of span gas (ppm)

NOx Emission Rate (lbs/hr) = PPMO * QO * MW* 60/(385.3*1000000)
Where: NOx – Nitrogen Oxides
PPMO – Average Concentration Of Corrected Pollutant At Outlet = 8.67 ppm
QO – Volumetric Flow Rate At Outlet (dscfm) = 21578.5 dscfm MW – Molecular Weight = 46.01
60 – Conversion factor (Minutes per Hour)
385.3 – Volume Occupied By One Pound Of Gas At Standard Condition (dscf/lb-mole)
1000000 – Conversion Factor (PPM To Mole Fraction)

= 8.67 * 21578.5 * 46.01* 60/(385.3*1000000)

= 1.34 lbs/hr
NOx Correction to 15% O2 = PPMO * (20.9 – 15) / (20.9 - O2)
Where:
NOx – Nitrogen Oxides
PPMO – Average Concentration of Corrected Pollutant at Outlet = 8.67 ppm O2 – Oxygen Concentration In Exhaust Stream = 15.7%

= PPMO * (20.9 – 15) / (20.9 - O2)
= 8.67 * (20.9 – 15) / (20.9 - 15.7)
= 10 ppm @ 15% O2
CO Emission Rate (lbs/hr)
= PPMO * QO * MW * 60/(385.3*1000000)
Where:
CO – Carbon Monoxide
PPMO – Average Concentration Of Corrected Pollutant At Outlet = 0.67 ppm QO – Volumetric Flow Rate At Outlet (dscfm) = 21578.5 dscfm MW – Molecular Weight = 28.01
60 – Conversion factor (Minutes per Hour)
385.3 – Volume Occupied By One Pound Of Gas At Standard Condition (dscf/lb-mole)
1000000 – Conversion Factor (PPM To Mole Fraction) = PPMO * QO * MW * 60/(385.3*1000000)

1.1 Introduction
An air emissions test program was conducted on a Solar Centaur 50 turbine, operated by
MountainWest Pipeline, LLC and designated as Unit T-2, located at the Blind Canyon
Compressor Station in Duchesne County, Utah. The purpose of the testing was to
demonstrate ongoing compliance with the emissions limits contained in Approval Order
#DAQE-AN130790006-12 and NSPS Subpart KKKK, for oxides of nitrogen (NOx) and
carbon monoxide (CO).
The Blind Canyon Compressor Station is utilized to boost the line pressure to accommodate
additional gas flow through the pipeline. The natural gas enters the station through a valve on
the main pipeline and flows through various filters and vortex separators to remove liquids
and other impurities (slugs) prior to compression. The filtered and separated impurities from
the pipeline are pumped to one of the on-site condensate storage tanks. After filtering, the
natural gas flows to the compressor engines where it is compressed to increase the pressure of
the gas. The temperature of the gas also increases upon compression. Therefore, after
compression the gas flows through an after cooler to be cooled to pipeline temperate prior to
being reintroduced to the main pipeline. Natural gas from the main pipeline is used to power
the on-site compressors and generators. The generators provide power for the facility and as
such, are not considered emergency backup generators.
Three, one hour test runs were performed on July 17, 2024 to analyze exhaust NOx and CO
emission levels in accordance with the procedures of 40 CFR 60(A) Methods 1, 3A, 7E, 10
and 19 and Subpart KKKK, as outlined in the submitted Source Test Protocol dated May 29,
2024. 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 and fuel
characteristics. Parameters include turbine gas producer speed, temperatures, and fuel gas
analysis.
The following key personnel were present during testing:

2.1 Stack Sampling Location
Sampling was conducted on the Solar Centaur 50 turbine (Unit T-2, SN OHC22-H7094). The
sampling ports for NOx and CO measurements were approximately 103.0" (2.9 pipe
diameters) downstream from the nearest flow disturbance (Distance B) and 45.0" (1.3 pipe
diameters) 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 12 traverse points determined
according to Table 1 below.

4.3 Process Parameters

Operating parameters recorded during testing were used in conjunction with a Solar program
to approximate the turbine load. Parameters include turbine gas producer speed and
temperatures. This was conducted and provided by MountainWest personnel. The supplied
fuel gas analysis was used to determine the Fd factor. Results are provided in Appendix C.

5.1 Quality Assurance

Precautions are taken to keep the gas analyzer in a clean, thermally stable, vibration free
environment to minimize analyzer drift and associated errors. Pre test calibrations and
most post test operations are performed within the testing trailer environment.

The data from the samples are converted directly into computer language and recorded in the
Compliance Specialist’s laptop computer. This eliminates the need for sample labeling and
secures the preservation of the data while reducing human error. In addition, parameters
associated with the turbine are recorded on test sheets at the time of the tests.

Preventive diagnostic functions are built directly into the equipment utilized for the testing.
This diagnostic function provides the Compliance Specialist with failure warnings allowing
the determination of when repairs are necessary without performing painstaking preventative
maintenance procedures. However, equipment is inspected regularly by the compliance
specialists and the Field Operations Manager to guarantee maximum operational status. The
process involved with equipment calibration ensures that there is no divergence from the
manufacturer’s specifications.

All pre and post calibration error checks, leak checks, and other quality assurance issues
conformed with the requirements specified in EPA 40 CFR 60(A), Methods 1, 3A, 7E, 10
and 19 and Subpart KKKK.

Linearity checks are performed using NOx, CO, O2 and Ultra High Purity Nitrogen certified
calibration gases to ensure that the zero, mid, and upscale calibrations are within the required
+/-2% of the certified calibration level and zero. Pre-Test calibrations are then conducted on
the zero and selected mid or upscale calibration gas determined by observing the native
concentration of the target analytes in the sampled exhaust. After each test run the same zero
and selected mid or upscale calibration gas are analyzed to verify they are within required
specifications. Calibration Error for post-test calibrations must remain within +/- 5% of the
certified calibration gas or zero. Drift is required to stay within +/- 3% during post-test
calibrations.

Example Calculations: MountainWest Pipeline, LLC, Blind Canyon
Compressor Station, T-2

The following is a step-by-step calculation for the first test run conducted on the Blind Canyon
Compressor Station T-2.

Test Parameters
 Average O2 = 15.8%  Turbine Load = 3666.0 bhp
EPA Method 19: Determination of Stack Gas Flow Rate
Volumetric Flow Rate At Outlet (dscfm) = q * Fd * 1E-6 * HHV * 20.9 / (20.9 - O2)
Where:
q – Fuel flow = 573.5 scf/min Fd – Fuel factor (dry) = 8630.5 dscf/mmBtu HHV – Higher Heating Value of fuel = 1060.84 Btu/scf
O2 – Oxygen content in exhaust (%) = 15.8% 1E-6 – Conversion from Btu to mmBtu

= q * Fd * 1E-6 * HHV * 20.9 / (20.9 - O2)
= 573.5 * 8630.5 * 1E-6 * 1060.84 * 20.9 / (20.9 - 15.8)

= 21653.5 dscfm

EPA Method 7E and 10: Determination of NOx and CO Emissions From Stationary Sources Corrected Flue Gas Concentration (PPM) = (CR - CO) * CMa / (CM – CO)
Where:
CR – Average flue gas concentration indicated by gas analyzer (ppm) CO – Average of initial and final zero system bias checks (ppm)
CM – Average of initial and final span system bias checks (ppm)
CMa – Actual concentration of span gas (ppm)

NOx Emission Rate (lbs/hr) = PPMO * QO * MW* 60/(385.3*1000000)
Where: NOx – Nitrogen Oxides
PPMO – Average Concentration Of Corrected Pollutant At Outlet = 3.98 ppm
QO – Volumetric Flow Rate At Outlet (dscfm) = 21653.5 dscfm MW – Molecular Weight = 46.01
60 – Conversion factor (Minutes per Hour)
385.3 – Volume Occupied By One Pound Of Gas At Standard Condition (dscf/lb-mole)
1000000 – Conversion Factor (PPM To Mole Fraction)

Docusign Envelope ID: F095A0C7-F55A-4E2E-8CFB-282192831E9E
= PPMO * QO * MW* 60/(385.3*1000000)
= 3.98 * 21653.5 * 46.01* 60/(385.3*1000000)

= 0.62 lbs/hr
NOx Correction to 15% O2 = PPMO * (20.9 – 15) / (20.9 - O2)
Where:
NOx – Nitrogen Oxides
PPMO – Average Concentration of Corrected Pollutant at Outlet = 3.98 ppm O2 – Oxygen Concentration In Exhaust Stream = 15.8%

= PPMO * (20.9 – 15) / (20.9 - O2)
= 3.98 * (20.9 – 15) / (20.9 - 15.8)
= 5 ppm @ 15% O2
CO Emission Rate (lbs/hr)
= PPMO * QO * MW * 60/(385.3*1000000)
Where:
CO – Carbon Monoxide
PPMO – Average Concentration Of Corrected Pollutant At Outlet = 1.07 ppm QO – Volumetric Flow Rate At Outlet (dscfm) = 21653.5 dscfm MW – Molecular Weight = 28.01
60 – Conversion factor (Minutes per Hour)
385.3 – Volume Occupied By One Pound Of Gas At Standard Condition (dscf/lb-mole)
1000000 – Conversion Factor (PPM To Mole Fraction) = PPMO * QO * MW * 60/(385.3*1000000)
= 1.07 * 21653.5* 28.01* 60/(385.3*1000000)

= 0.10 lbs/hr
