Introduction:
Emissions Science, Inc. was contracted to perform a series of source compliance tests at the Vernal Compressor Station located in Uintah County, Utah and operated by
Northwest Pipeline GP. The tested source was a Solar Taurus 70 Model T-10302S fitted with a compressor package. The Solar Taurus Turbine is used to compress natural gas
into a pipeline for delivery.
The testing was required by the U.S. EPA Region 8 and the State of Utah, DAQ. The turbine was required to meet the emission standards set forth in NSPS 40 CFR Part 60,
Subpart KKKK.
One source was tested for concentrations of Nitrogen Oxides (NOx) to satisfy the standards mandated by 40 CFR Part 60, Subpart KKKK.
All testing was done under the guidelines and within allowable tolerances under: 40 CFR Part 60.
Test Methods:
The specific EPA Test Methods used in this source testing program are as follows;
 Method 1: Method 1: Sample and Velocity Traverses Stack inside diameter determination.
Proper sample port location as based on upstream / downstream disturbance distance.
Stack Gas Stratification Test.
 Method 3A: Determination of Oxygen & Carbon Dioxide Concentrations.
 Method 7E: Determination of Nitrogen Oxides Emissions.
Tested Source:
Three, twenty-minute sample runs were performed on the combustion turbine detailed on the following page. The source was tested at the maximum available load based on site
conditions and facility production capabilities on the test date.

Compressor Station operated by Northwest Pipeline, LLC. The source is a Solar Taurus Model 70-10302S Simple Cycle Combustion Turbine used to compress natural gas into a
pipeline. The turbines were tested under the requirements found under NSPS - 40 CFR part 60, Subpart KKKK.
ESI used an emissions gas analyzer based on Chemiluminescence technology for the measurement of Nitrogen Oxides (NOx) and a paramagnetic based sensor for O2 to
measure the concentrations at the EPA compliant sample port of the combustion turbine.
The analyzer sensors were put through an intensive series of calibration and sampling system bias checks to ascertain quality assurance of the data prior to performing any
compliance testing. This calibration data can be found in the applicable appendix for the sampled source. The data from the source test was collected over each 20-minute test
period in one-minute increments and then averaged over the total sample run. This data was then transferred to a laptop computer where it was entered into the test forms.
Analyzer bias checks were also performed on each measured component after the completion of each test run.
A sample line heated to keep the sample gas at a temperature above the condensation
point (approximately 250 degrees F) was used to transport the sample gas to the emissions analyzers and the moisture removal system. A leak check was performed on
the entire sampling system before the commencement of any sample runs and the check indicated no system leaks.
The test program was designed to meet the concentration limits for new turbines firing natural gas in the category of, > 50 MMBtu/hr - < 850 MMBtu/hr as is noted in table one
(NOx Emission Standards) of the NSPS 40 CFR Part 60, Subpart KKKK Final Rule. The concentration limit for this source was NOx 25 ppmvd corrected to the diluent
concentration of 15% O2.
The source was operating in a normal condition during the test program and was reportedly at maximum achievable load on the test date.

Detailed Sampling Description (Continued).

Although not required under the KKKK test method, EPA Method 19 was used with the
industry standard value of 8710 SCF/MMBtu and the bias corrected Nitrogen Oxide and
Oxygen concentrations to determine mass emission rates for the purposes of verifying the
mass emission rates requirements for NOx by the Utah, DAQ permit for this facility.

EPA Method 205 was used to dilute an NO calibration gas to a level appropriate with the
measured stack concentrations. The mandatory field test was completed successfully in
triplicate demonstrating the mass flow controllers were functioning correctly.

For the purposes of this test program, Sulfur Dioxide (SO2) was not measured in the
exhaust stream as Northwest Pipeline LLC has elected to periodically monitor the sulfur
content in the fuel gas as is allowed under section § 60.4370 in the 40 CFR Part 60,
Subpart KKKK Final Rule. A recent fuel-gas analysis or Tarif Sheet indicating sulfur
compounds are at allowable levels can be found within appendix 8 in this report.

After each test, all measured parameters, (NOx, & O2) were checked for consistency by
comparing the analyzer values to EPA 1 Protocol Calibration Gases. The measured
values were then corrected for span and zero analyzer drift and concentration rates as
well as mass emission rates were then calculated based on these corrected concentrations.

All other Q/A – Q/C procedures such as; an NO2 converter oven efficiency test (prior to
and after the completion of the test program) and barometric pressure measurements from
a nearby location shown by the National Weather Service (corrected to site elevation)
were followed and based on this and other data, the source tests for these turbines were
deemed to be accurate and valid.

A stratification test from an EPA compliant sample port on the turbine was performed by
E.S.I. prior to testing and the stack was found to be minimally stratified (< 5%) as
allowed under EPA Method 1 and 7E, so single point sampling near the center of the duct
was found to be a technically sound procedure for this testing program.

Sample Calculations

Note: As the calculations, formulae and unit conversions used for these test procedures are too numerous to list, the following is a selection of the primary calculations used in the selected method.
EPA Reference Method 1
• Stack Diameter * Distance Percentage from Stack Wall (Based on # of Traverse Points from Table F1-2)
• Disturbances up & downstream from sample ports (minimum 2* diameter downstream and 0.5 * diameter upstream.
EPA Method 7E (Section 8.1.2 Stratification Testing)

• Minimum Requirement: Measure across single stack plane and record concentrations at points 16.7, 50.0 & 83.3% from stack wall. Results indicating
< 5% stratification will be considered “non-stratified” and single-point sampling from the approximate center of the duct is a viable technique.
Results > 5% Stratification will require multi-point sampling. (Avg. 3 points – Point 1, 2,3) / Avg.3 Points * 100 11.1 Calibration Corrections—The tester may choose to correct the emissions data
for a test run using the pretest and post-test calibration error results according to the
following formula:
CGAS = (Cr – Co) CMA / Cm - Co

Where: CGAS = corrected flue gas concentration CR = flue gas concentration indicated by gas analyzer,
CO = average of initial and final zero checks,
CM = average of initial and final span checks, and
CMA = actual concentration of span gas.
Measured Concentration Nitrogen Oxides Corrected to 15 % O2.
(Measured NOx concentration * (5.9/20.9- Measured O2 Concentration))

Quality Assurance / Quality Control Plan
40 CFR Part 60, Subpart KKKK

• Verification of Correct Calibration Gas Selection and check on expiration dates.
• Use of non-reactive sample transport and probe material (stainless-steel, glass, PTFE)
and line heated above condensation point.
• Linearity and stability tests performed on each sensor used in the compliance test. These
tests are valid for 5 days after the successful completion (ASTM D6522-00).

• System Leak Check

• Pre-Test & Post-Test Bias Challenges. Analyzer Reading vs. EPA Protocol Gases.

• Exhaust Stack measured for potential stack-gas stratification. Stratification tests will
determine single-point or multiple-point sampling.

• NOx Convertor Oven Test (Before and After Compliance Test)

• One-minute intervals for data recorder on sample run data (averaged at end of run).

• Calibration and run ‘raw’ data preserved as indelible record.

Report Introduction:

Emissions Science, Inc. was contracted to perform a series of source compliance tests at the Vernal Compressor Station located in Uintah County, Utah and operated by NW
Pipeline GP. The Vernal Facility is a natural gas compression station and the tested source provides backup emergency electricity in the case of a pole-power interruption.
The testing was required by the U.S. EPA Region 8. This engine was required to meet the
emission standards set forth in NSPS 40 CFR Part 60, Subpart JJJJ. One source (EG-1) was tested for concentrations of Nitrogen Oxides (NOx), Carbon
Monoxide (CO) and Volatile Organic Compounds (NMEOC’s). All testing was done under the guidelines and within allowable tolerances under: 40 CFR Part 60.
Test Methods:
The specific EPA Test Methods used in this source testing program are as follows;
 Method 1: Sample and Velocity Traverses Stack inside diameter determination.
Proper sample port location as based on upstream / downstream disturbance distance.
Stack Gas Stratification Test.
 Method 3A: Determination of Oxygen & Carbon Dioxide Concentrations.
 Method 4: Determination of Moisture Content in Stack Gases.
 Method 7E: Determination of Nitrogen Oxides Emissions.
 Method 10: Determination of Carbon Monoxide Emissions

 Method 25A (Alt-106): Determination of Total Gaseous Organic Concentrations
(using a flame ionization detector equipped with a non-methane cutter).

Tested Source:
Three, one-hour sample runs were performed on the source described below. The source was operating in a normal condition and a load-bank was used to get appropriate load on
the generator engine for testing. The source was reportedly at the maximum available load based on site conditions and facility production capabilities on the test date.
The source is used to generate electricity for the Vernal Facility.
The tested source is described below: EG-1 - Caterpillar 3412 C TA, Four-cycle, lean-burn (RICE). Site Rated at 637 BHP.
Serial # CTP02968. This engine is controlled with a Caterpillar factory installed Air / Fuel Ratio Controller (AFR). It could not be determined if the AFR operates based on O2
or NOx concentrations. The source was not equipped with an oxidation catalyst system. Test Results:
The tested source (EG-1) at the Vernal Compressor Station was found to be in compliance for the pollutants of CO, NOx, and VOC’s (as NMNEOC) based on the
allowable concentration limits corrected to the diluent concentration of 15% O2.

Detailed Sampling Description:
Emissions Science, Inc. (ESI) tested the exhaust stack of one source (EG-1) at the Vernal Compressor Station operated by NW Pipeline GP. The Caterpillar G 3412 TA engine is
used to generate backup emergency electricity for the facility. The engine was tested under the requirements found under EPA - 40 CFR Part 60, Subpart JJJJ.
ESI used an emissions gas analyzer based on non-dispersive infra-red (NDIR) technology for the measurement of CO and CO2, a paramagnetic based sensor for O2 and a Chemiluminescence based analyzer for NOx to measure the concentrations from the exhaust stack.
A Flame Ionization Detector (FID) equipped with a Gas Chromatograph (GC) was used
to measure the organic compounds from the exhaust stack under EPA Method 25A (& ALT-106). Organic compounds C3 or heavier were measured as Propane and were the
target compound for this testing event. Concentrations and mass emission rates for VOC’s were derived from the propane measurements. The analytes, methane and ethane
are also shown on the chromatograms but were not counted as VOC’s. All measured analytes met acceptable calibration requirements before and after the sampling program.
Four, Tedlar sample bags were collected from the stack at various times during each sample run (approximately 15-minute intervals). Each bag was then analyzed
individually to provide an average representing the entire sample run.
After the known retention time of ethane had passed, the valve on the GC was set to rotate and a back-flush was performed in order to measure NMNE hydrocarbons. Theses
hydrocarbons were measured as propane and the measured values were then entered into the tests form where they were corrected for sample system bias and stack moisture
content. The chromatograms can be found at the end of Appendix 1 and are separated by sample run.
The bias corrected concentrations were then normalized to the standard of 15% Oxygen
for comparison to the emission limits found under, 40 CFR Part 60, Subpart JJJJ.
The analyzers were put through an intensive series of calibration and sampling system bias checks to ascertain quality assurance of the data prior to performing any compliance
testing. This calibration data can be found in the applicable appendices for the sampled source. The data from the source test was collected over each, 60-minute test period in
one-minute increments and then averaged over the total sample run. This data was then transferred to a laptop computer where it was entered into the test forms.

Detailed Sampling Description (continued).
A sample line heated to keep the sample gas at a temperature above the condensation point (approximately 255 degrees F) was used to transport the sample gas to the
emissions analyzers. A leak check was performed on the entire sampling system before the commencement of any sample runs and the results were zero leaks.
A series of moisture knock-out impingers were used in conjunction with a dry, gas-meter to gravimetrically measure the moisture content of the stack gas. Multiple leak checks were performed on the entire moisture train system and the results indicated zero leakage.
After each sample run, all measured parameters CO, NOx, O2, CO2 and organics (C3 and heavier as propane) were checked for consistency by comparing the analyzer values to
EPA Protocol or Primary Standard Calibration Gases (both with 1% relative uncertainty). The measured values were corrected for span and zero analyzer drift.
A stratification test was performed on the exhaust stack of this source and the results
indicated minimal stratification (< 5%) of the exhaust gases. As indicated in EPA Method 7E (Section 8.1.2) the measured results from the stratification test indicated single-point
sampling from a point near the center of the duct was a technically sound procedure for this source.
All other Q/A – Q/C procedures such as; a NO2 converter oven efficiency test, NIST
traceable equipment to verify temperature and altitude corrected barometric pressure measurements obtained from a nearby NOAA weather station were followed and based
on this and other data, the source test for this generator engine was deemed to be accurate and valid.
Horsepower:

The horsepower values for the test runs were obtained by using Caterpillar engine display screen with produced kilo-watts (kW). The following equation was used to calculate HP.
(kW*1.732*0.996/0.746) where 0.996 is the power factor for triple-phase power shown on the panel. The source was reportedly operating at maximum achievable load during
the test program. Source Test Deviations:

VOC corrected to ppmvd = (Bias Corrected VOC Concentration / (1-Stack Moisture Content %))
Lb/Hr VOC (as C3H8) = Lb/hr = corrected concentration ppmvd *(DSCF/M) (1.556*10^-7) (44.1)
Corrected VOC @ 15% O2 = Bias Corrected VOC * (5.9/(20.9-Corrected O2)
Ton/Year = Lb/Hr * 8760/2000
g/bhp-hr = ppm*1.833*10^-3*M3*60/bhp (EPA 4J Equation)
g/BHP-Hr = (lb/hr*453.6)/hp

Method 25 Methane/Nonmethane GC System 18

FID Detector
HayeSep-D Column
10-port "Backflush" Gas Sampling Valve
Built-in "whisper quiet" Air Compressor
1 channel PeakSimple Data System
...on the compact 8610C chassis
The SRI Method 25 GC system is equipped with an FID detector, built-in air compressor, and a 10-port Backflush gas sampling valve to quickly determine methane/non-methane hydrocarbons as per EPA Method 25.
In this typical methane/non-methane analysis, the non-methane hydrocarbons were backflushed after the ethane peak, but the valve timing could have been set to backflush after the methane, or after the
C3, C4, C5 or C6 hydrocarbons,
depending on the operator's needs.
The sample is connected to the valve inlet port on the GC valve oven, where it fills the 1mL sample loop on the gas sampling valve. The valve is then automatically rotated to inject the sample onto the column, which separates the methane (and optionally the ethane) away from the rest of the hydrocarbons. After the elution of the compound(s) of interest, the gas sampling valve is automatically returned to the starting position, which backflushes the rest of the hydrocarbons into the detector.
The single channel PeakSimple data system controls the temperature programmable column oven and the gas sampling valve, collects the data, quantitates the non-methane hydrocarbons, and produces a printed report. The Method 25 GC comes standard with a HayeSep-D column, but may be equipped with other column types as desired.
(VOLTAGE: for 110VAC, use 8610-0025-1 for 220VAC, use 8610-0025-2)

Sample Calculations for EPA Reference Method Tests
Note: As the calculations, formulae and unit conversions used for these test procedures are too numerous to list, the following is a selection of the primary calculations used in the various methods.
EPA Reference Method 1
• Stack Diameter * Distance Percentage from Stack Wall
(Based on # of Traverse Points from Table F1-2) EPA Reference Method 2
• Section 12.5: Molecular Weight of Stack Gas Ms = Md (1 – Bws) + 18.0*Bws …Eq. 2-6
Where:
Ms = Molecular weight of stack gas, wet basis… (lb/lbmole) Md = Molecular weight of stack gas, dry basis Bws = Water vapor in the gas stream proportion by volume
Section 12.6: Average Stack Gas Velocity
o KPCP√∙Pavg√(Ts(abs) / PsMs) …Eq. 2-7

• 85.49 m/sec [(1b/1b-mole) (in. Hg) / (oR) (in. H20)]1/2
Where: Kp = Velocity equation constant. Cp = Pitot tube coefficient, dimensionless
·Pavg = Average velocity head of stack gas… (in. H2O)
Ts(abs) = Absolute stack temperature… (oR)
Ps = Absolute stack pressure (Pbar + Pg)… (in. Hg) Ms = Molecular weight of stack gas, wet basis… (lb/lbmole

• Section 12.7: Average Stack Gas Dry Volumetric Flow Rate o Q = 3600 (1-Bws) Vs A[ Tstd Ps / Ts(abs) Pstd] …Eq. 2-8
Where: 3600 = Conversion Factor… (Sec/hr) Bws = Water vapor in the gas stream proportion by volume
Vs = Average stack gas velocity… (ft/sec)
A = Cross-sectional area of stack… (ft2)
Tstd = Standard absolute temperature… (528 oR) Ts(abs) = Absolute stack temperature… (oR) Pstd = Standard absolute pressure… (29.92 in. Hg)

Sample Calculations for EPA Reference Method Tests
EPA Method 7E (Section 8.1.2 Stratification Testing)
• Minimum Requirement: Measure across single stack plane and record
concentrations at points 16.7, 50.0 & 83.3% from stack wall. Results indicating < 5% stratification will be considered “non-stratified” and single-point
sampling from the approximate center of the duct is a viable technique. Results > 5% Stratification will require multi-point sampling.
(Avg. 3 points – Point 1, 2,3) / Avg.3 Points * 100

11.1 Calibration Corrections—The tester may choose to correct the emissions data for a test run using the pretest and post-test calibration error results according to the following formula: CGAS = (Cr – Co) CMA / Cm - Co
Where: CGAS = corrected flue gas concentration
CR = flue gas concentration indicated by gas analyzer,
CO = average of initial and final zero checks, CM = average of initial and final span checks, and CMA = actual concentration of span gas.
Measured Concentration Carbon Monoxide Corrected to 15 % O2.
(Measured CO concentration * (5.9/20.9- Measured O2 Concentration))

ER (Emission Rates)
Lb/hr = Bias Corrected CO ppm *DSCFM *(1.556*10^-7)*28.01 Gram/BHP-Hr = (lb/hr*453.6)/hp

Note: The proceeding test calculations are examples of the equations used in the testing procedures.
Additional or alternate EPA approved equations may also be used during the testing program. Some formulae appear in the report where actually used.
