2.0 Sampling System
The sampling system used consisted of a Stainless steel probe, heated Teflon line, gas conditioning
system, and a Gasmet model DX4000 FTIR analyzer. The gas conditioning system used was a Gasmet
Personal Sampling System with a Zirconium Oxide oxygen sensor.
3.0 Methods Used
This extractive FTIR based field test method is used to quantify gas phase concentrations of multiple target
analytes (CO, NOX, CH2O, & VOC's) from stationary source effluent. Because an FTIR analyzer is
potentially capable of analyzing hundreds of compounds, this test method is not analyte or source specific.
The analytes, detection levels, and data quality objectives are expected to change for any particular testing
situation. It is the responsibility of the tester to define the target analytes, the associated detection limits for
those analytes in the particular source effluent, and the required data quality objectives for each specific
test program. Provisions are included in this test method that require the tester to determine critical
sampling system and instrument operational parameters, and for the conduct of QA/QC procedures.
Testers following this test method will generate data that will allow an independent observer to verify the
valid collection, identification, and quantification of the subject target analytes.
EPA Method 1 & 1A
EPA Method 2 & 2C
EPA Method 3A
The purpose of the method is to provide guidance for the selection of sampling ports and traverse points at
which sampling for air pollutants will be performed pursuant to regulations set forth in this part.
This method is applicable for the determination of the average velocity and the volumetric flow rate of a gas
stream. The average gas velocity in a stack is determined from the gas density and from measurement of
the average velocity head with a standard pitot tube. Velocity readings are taken from each stack at 16
separate traverse points (Table 6.1) and used to determine the engines mass emissions rate, calculated
utilizing the formulas seen in section 7.0 of this report.
This is a procedure for measuring oxygen (O2) and carbon dioxide (CO2) in stationary source emissions
using a continuous instrumental analyzer. Quality assurance and quality control requirements are included
to assure that the tester collects data of known quality. Documentation to these specific requirements for
equipment, supplies, sample collection and analysis, calculations, and data analysis will be included.

8.1 Calibration error test; how do I confirm my analyzer calibration is correct? After the tester has assembled, prepared and calibrated the
sampling system and analyzer, they conduct a 3-point analyzer calibration error test before the first run and again after any failed system bias test or
failed drift test. They then introduce the low-, mid-, and high-level calibration gases sequentially in direct calibration mode. At each calibration gas level
(low, mid, and high) the calibration error must be within ± 2.0 percent of the calibration span.
8.0 Oxygen Calibration
8.2 Initial system bias and system calibration error checks. Before sampling begins, it is determined whether the high- level or mid-level
calibration gas best approximates the emissions and it is used as the upscale gas. The upscale gas is introduced at the probe upstream of all sample-
conditioning components in system calibration mode.
8.3 Post-run system bias check and drift assessment - confirming that each sample collected is valid. Sampling may be performed for multiple
runs before performing the post-run bias or system calibration error check provided this test is passed at the conclusion of the group of runs. A failed
final test in this case will invalidate all runs subsequent to the last passed test.
(1) Next, zero gas is introduced as described above. The response must be within 0.5 percent of the upscale gas concentration.
(2) Low-level gas reading is observed until it has reached a final, stable value and the results are recorded. The measurement system will be
operated at the normal sampling rate during all system bias checks.
(3) If the initial system bias specification is not met, corrective action is taken. The applicable calibration error test from Section 8.2.3 of EPA
Method 7E is repeated along with the initial system bias check until acceptable results are achieved, after which sampling will begin. The pre-
and post-run system bias must be within ± 5.0 percent of the calibration span for the low-level and upscale calibration gases.
(1) If the post-run system bias check is not passed, then the run is invalid. The problem is then diagnosed and fixed, then another calibration
error test and system bias is passed before repeating the run.
(2) After each run, the low-level and upscale drift is calculated, using Equation 7E–4 in Section 12.5 from EPA Method 7E. If the post-run low-
and upscale bias checks are passed, but the low-or upscale drift exceeds the specification in Section 13.3, the run data are valid, but a 3-point
calibration error test and a system bias check must be performed and passed prior to additional testing.

Method 7E 3.4 To the extent practicable, the measured emissions should be between

cases of low concentration measurements or testing for compliance with an emission
limit when emissions are substantially less than the limit.

Annex 1.2
The test quality objectives completed for the emissions test are demonstrated throughout Annexes 1, 2, 3,
4, 5, 6, 7 & 8 as layed out per ASTM D6348-03. All reference methods, pre-test and post test procedures
were within acceptable limits. Data generated during the pre-test and post-test procedures are
summarized below in order of the distinctive Annex.
Three 60 minute test runs were performed. The final analyte concentrations are the average of each test
run. Data was taken at 60 second intervals. Each 60 second measurement was the average of 600 scans.
Propane is used as the surrogate compound for the Annex 5 Spiking Technique due to Propane being the
VOC that is most commonly found in the combustion process of natural gas.  Additionally, the molecular
weight of Propane coincides with with molecular weight of VOC's per the EPA.

Mr. Jordan Williamson
CEO
GAS Inc.
303 W. 3rd Street
Elk City, OK 73644
Dear Mr. Williamson:
We are writing in response to your letter received on September 17, 2020, in which you request the approval
of alternative testing procedures. The EPA’s Office of Air Quality Planning and Standards (OAQPS) is the
delegated authority for consideration of major alternatives to test methods and procedures as set forth in 40
CFR parts 60 and 63 under which your request must be addressed. GAS Inc. is requesting a change to one of
the test methods, ASTM D6348-03, used for conducting performance tests to determine compliance under
40 CFR part 60, Subpart JJJJ – Standards of Performance for Stationary Spark Ignition Internal Combustion
Engines (Subpart JJJJ) and 40 CFR part 63, Subpart ZZZZ – National Emissions Standards for Hazardous
Air Pollutants for Performance for Stationary Reciprocating Internal Combustion Engines (Subpart ZZZZ).
The change being requested will be used to check detector linearity of the Fourier Transform Infrared (FTIR)
instrumentation used to conduct this method. Specifically, you are requesting that the procedures of section
8.3.3 of Method 320 (40 CFR part 60, Appendix A), another FTIR-based method allowed under Subparts
JJJJ and ZZZZ, be used in lieu of section A6.4.1 of ASTM D6348-03 when conducting testing using ASTM
D6348-03 under 40 CFR part 60, Subpart JJJJ and 40 CFR part 63, Subpart ZZZZ.
In your request, you state that this alternative linearity check procedure will produce consistent results when
utilizing either Method 320 or ASTM D6348-03. Additionally, some FTIR instrumentation does not allow
for reducing the size of the aperture in the instrument and, thus, it would not be feasible to properly conduct
the entirety of the ASTM D6348-03 method in its current form using such an instrument.
Based on our understanding of FTIR instrument principles and recognition that the requested alternative
determination of detector linearity is both technically sound and contained within Method 320, we are
approving the requested change. We believe that this alternative is acceptable for use for use in testing all
engines subject to 40 CFR part 60 Subpart JJJJ and 40 CFR part 63, Subpart ZZZZ. Also, we will post this
letter as ALT-141 on EPA’s website (at www.epa.gov/emc/broadly-applicable-approved-alternative-
testmethods) to announce that our approval of this alternative test method is broadly applicable to engines for
the purposes of meeting Subparts JJJJ and ZZZZ.
March 15, 2021
Sincerely,
Steffan M. Johnson, Group Leader
Measurement Technology Group
If you should have any questions or require further information regarding this approval, please contact David
Nash of my staff at 919-541-9425 or email at [e-mail].

1.1 Introduction

An air emissions test program was conducted on a Caterpillar G3516LE engine, operated by
Ovintiv USA Incorporated and designated as Unit #2, located at the Pleasant Valley
Compressor Station in Duchesne County, Utah. The purpose of the testing was to
demonstrate annual compliance with the emissions limits contained in UDEQ Permit
#DAQE-AN0142100007-23 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 adjacent to the Ovintiv Myton Field Office 10530 South, County Road
33 Myton, UT 84052.
576,723 m Easting, 4,444,226 m Northing, UTM Zone 12

Three one hour test runs were performed on August 27, 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 as outlined in the submitted
Source Test Protocol dated May 17, 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.
Parameters include the engine RPM, air intake temperature, intake manifold pressure and site
elevation.

The following key personnel were present during testing:

TJ Schmidtberger, OEC
Brian Webb, Ovintiv

1.2 Deviation

EPA 40 CFR 60(A) Method 3 was used instead of Method 3A for the determination of CO2
and O2 as was submitted in the original test protocol.

2.1 Stack Sampling Location

The facility is located adjacent to the Ovintiv Myton Field Office 10530 South, County Road
33 Myton, UT 84052.
576,723 m Easting, 4,444,226 m Northing, UTM Zone 12

Testing was conducted on the Caterpillar G3516LE engine. The sampling port for moisture,
NOx, CO and VOC measurements was approximately 3.1 pipe diameters (36”) downstream
from the nearest flow disturbance (Distance B) and 10.4 pipe diameters (120”) 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 August 27, 2024 to analyze exhaust NOx, CO
and VOC (NMNEHC C3) emission levels to demonstrate annual compliance with the
emissions limits contained in the WDEQ Permit #DAQE-AN0142100007-23 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.

Based on operating parameters recorded during testing, the average, maximum load
was approximated at 892.6 bhp, and the average NOx and CO levels were found to be
1.82 lbs/hr and 0.01 lbs/hr respectively, below limitations. The VOC level tested at
0.21 lbs/hr, which tested in compliance.

3.1.2 Source Test 2: Caterpillar G3516LE, NOx, CO and VOC

The second test was performed from 10:50 to 11:49 for NOx, CO and VOC.

Based on operating parameters recorded during testing, the average, maximum load
was approximated at 892.6 bhp, and the average NOx and CO levels were found to be
1.72 lbs/hr and 0.01 lbs/hr respectively, below limitations. The VOC level tested at
0.22 lbs/hr, which tested in compliance.

3.1.3 Source Test 3: Caterpillar G3516LE, NOx, CO and VOC

The third test was performed from 11:51 to 12:50 for NOx, CO and VOC.

Based on operating parameters recorded during testing, the average, maximum load
was approximated at 892.6 bhp, and the average NOx and CO levels were found to be

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.

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
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 RPM, air intake temperature, intake manifold pressure and site elevation. 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 90.1%, 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.

EPA 40 CFR 60(A) Methods 1-3: Determination of Stack Gas Velocity and Flow Rate

Dry Molecular Weight (lb/lbmol)
= (0.44 * %CO2) + (0.32 * %O2) + ((0.28 * (%N2 + %CO))

Where:
%CO2 – Carbon Dioxide Content Of The Gas = 7.2%
%O2 – Oxygen Content Of The Gas = 7.9%
%N2 – Nitrogen Content Of The Gas
%CO – Carbon Monoxide Content Of The Gas

(%N2 +%CO) = (100 - %O2 - %CO2)

= (100 – 7.9 – 7.2)

= 84.9% Dry

= (0.44 * %CO2) + (0.32 * %O2) + ((0.28 * (%N2 + %CO))

= (0.44 * 7.2) + (0.32 * 7.9) + (0.28 * 84.9)

= 29.47 lb/lbmol

Wet Molecular Weight (lb/lbmol)
= MD * (1-BWS) + (18) * BWS

Where:
MD – Molecular Weight Of The Dry Gas (lb/lbmol) = 29.47 lb/lbmol
BWS – Moisture Content Of The Gas (%/100) = 12.71%

= MD * (1-BWS) + (18) * BWS

= 29.47 * (1 – (12.71/ 100)) + (18 * (12.71/ 100))

= 28.01 lb/lbmol

Average Stack Gas Velocity (ft/sec)
= Cp * (85.49) * ∆PAVG * (TS / (((PS / 13.6) + PB) * MA))

Where:
CP – Pitot tube constant (unitless) = 0.84
∆PAVG – Average square root of the stack gas pitot DP (inches water) = 1.230 in H2O
TS – Average stack temperature (R) = 1276 R
PB – Barometric pressure (in Hg) = 25.01 in Hg
PS – Stack pressure relative to barometric pressure (inches water) = 0.4 in H2O
MA – Molecular weight of the wet gas (lb/lbmol) = 28.01 lb/lbmol

= Cp * (85.49) * ∆PAVG * (TS / (((PS / 13.6) + PB) * MA))

= 0.84 * (85.49) * 1.230 * ( 1276 / (((0.4/ 13.6) + 25.01) * 28.01))

= 119.19 ft/sec

Average Dry Flowrate (dscfm)
= 60 * (1-BWS) * VS *  * (((DS / 2) / 12))2)* TSTD / TS * (PB + (PS / 13.6)) / 29.92

Where:
DS – Diameter of the stack (inches) = 11.5 inches
BWS – Moisture content of the gas (%) = 12.71%
TSTD – Standard temperature (528R)
TS – Average stack temperature (R) = 1276 R
PB – Barometric pressure (in Hg) = 25.01 in Hg
PS – Stack pressure relative to barometric pressure (inches water) = 0.4 in H2O
VS– Average Stack gas velocity (ft/sec) = 119.19 ft/sec

= 60 * (1-BWS) * VS *  * (((DS / 2) / 12))2)* TSTD / TS * (PB + (PS / 13.6)) / 29.92

= 60 * (1 - (12.71/ 100)) * 119.19 *  * (((11.5 / 2) / 12))2) * 528 / 1276 * (25.01 + (0.4 /
13.6)) / 29.92

= 1559.18 dscfm

Conversion of Dry Flowrate to m3/hr
= Q * 60 * 2.83168*10 -2

Where:
Q – Volumetric Flowrate = 1559.18 dscfm
2.83168*10 -2 – Conversion factor for cubic feet to cubic meter
60 – Minutes in an hour

= Q * 60 * 2.83168*10 -2

= 1559.18 *60 * 2.83168*10 -2

= 2649.06 m3/hr

ASTM D 6348-03: Determination of NOx, CO and VOC Emissions From Stationary Sources

NOx Emission Rate (g/Bhp-hr)
= (Cd * 1.912*10 -3 * Q * T) / HP-hr

Where:
Cd – Measured NOx concentration in ppm = 162.83 ppm
1.92*10 -3 - Conversion constant for ppm to g/m3 NOx
Q – Volumetric Flowrate = 2649.06 m3/hr
T – Time in Hours of Test Run = 1 hr
HP-hr – Unit Brake Horsepower = 892.6 Bhp

= (Cd * 1.912*10 -3 * Q * T) / HP-hr

= (162.83 * 1.912*10 -3 * 2649.06 * 1) / 892.6

= 0.92 g/Bhp-hr

NOx Emission Rate (lbs/hr)

2.0 Sampling System
The sampling system used consisted of a Stainless steel probe, heated Teflon line, gas conditioning
system, and a Gasmet model DX4000 FTIR analyzer. The gas conditioning system used was a Gasmet
Personal Sampling System with a Zirconium Oxide oxygen sensor.
3.0 Methods Used
This extractive FTIR based field test method is used to quantify gas phase concentrations of multiple target
analytes (CO, NOX, CH2O, & VOC's) from stationary source effluent. Because an FTIR analyzer is
potentially capable of analyzing hundreds of compounds, this test method is not analyte or source specific.
The analytes, detection levels, and data quality objectives are expected to change for any particular testing
situation. It is the responsibility of the tester to define the target analytes, the associated detection limits for
those analytes in the particular source effluent, and the required data quality objectives for each specific
test program. Provisions are included in this test method that require the tester to determine critical
sampling system and instrument operational parameters, and for the conduct of QA/QC procedures.
Testers following this test method will generate data that will allow an independent observer to verify the
valid collection, identification, and quantification of the subject target analytes.
EPA Method 1 & 1A
EPA Method 2 & 2C
EPA Method 3A
The purpose of the method is to provide guidance for the selection of sampling ports and traverse points at
which sampling for air pollutants will be performed pursuant to regulations set forth in this part.
This method is applicable for the determination of the average velocity and the volumetric flow rate of a gas
stream. The average gas velocity in a stack is determined from the gas density and from measurement of
the average velocity head with a standard pitot tube. Velocity readings are taken from each stack at 16
separate traverse points (Table 6.1) and used to determine the engines mass emissions rate, calculated
utilizing the formulas seen in section 7.0 of this report.
This is a procedure for measuring oxygen (O2) and carbon dioxide (CO2) in stationary source emissions
using a continuous instrumental analyzer. Quality assurance and quality control requirements are included
to assure that the tester collects data of known quality. Documentation to these specific requirements for
equipment, supplies, sample collection and analysis, calculations, and data analysis will be included.

8.1 Calibration error test; how do I confirm my analyzer calibration is correct? After the tester has assembled, prepared and calibrated the
sampling system and analyzer, they conduct a 3-point analyzer calibration error test before the first run and again after any failed system bias test or
failed drift test. They then introduce the low-, mid-, and high-level calibration gases sequentially in direct calibration mode. At each calibration gas level
(low, mid, and high) the calibration error must be within ± 2.0 percent of the calibration span.
8.0 Oxygen Calibration
8.2 Initial system bias and system calibration error checks. Before sampling begins, it is determined whether the high- level or mid-level
calibration gas best approximates the emissions and it is used as the upscale gas. The upscale gas is introduced at the probe upstream of all sample-
conditioning components in system calibration mode.
8.3 Post-run system bias check and drift assessment - confirming that each sample collected is valid. Sampling may be performed for multiple
runs before performing the post-run bias or system calibration error check provided this test is passed at the conclusion of the group of runs. A failed
final test in this case will invalidate all runs subsequent to the last passed test.
(1) Next, zero gas is introduced as described above. The response must be within 0.5 percent of the upscale gas concentration.
(2) Low-level gas reading is observed until it has reached a final, stable value and the results are recorded. The measurement system will be
operated at the normal sampling rate during all system bias checks.
(3) If the initial system bias specification is not met, corrective action is taken. The applicable calibration error test from Section 8.2.3 of EPA
Method 7E is repeated along with the initial system bias check until acceptable results are achieved, after which sampling will begin. The pre-
and post-run system bias must be within ± 5.0 percent of the calibration span for the low-level and upscale calibration gases.
(1) If the post-run system bias check is not passed, then the run is invalid. The problem is then diagnosed and fixed, then another calibration
error test and system bias is passed before repeating the run.
(2) After each run, the low-level and upscale drift is calculated, using Equation 7E–4 in Section 12.5 from EPA Method 7E. If the post-run low-
and upscale bias checks are passed, but the low-or upscale drift exceeds the specification in Section 13.3, the run data are valid, but a 3-point
calibration error test and a system bias check must be performed and passed prior to additional testing.

Method 7E 3.4 To the extent practicable, the measured emissions should be between

cases of low concentration measurements or testing for compliance with an emission
limit when emissions are substantially less than the limit.

The test quality objectives completed for the emissions test are demonstrated throughout Annexes 1, 2, 3,
4, 5, 6, 7 & 8 as layed out per ASTM D6348-03. All reference methods, pre-test and post test procedures
were within acceptable limits. Data generated during the pre-test and post-test procedures are
summarized below in order of the distinctive Annex.
Three 60 minute test runs were performed. The final analyte concentrations are the average of each test
run. Data was taken at 60 second intervals. Each 60 second measurement was the average of 600 scans.
Propane is used as the surrogate compound for the Annex 5 Spiking Technique due to Propane being the
VOC that is most commonly found in the combustion process of natural gas.  Additionally, the molecular
weight of Propane coincides with with molecular weight of VOC's per the EPA.

Mr. Jordan Williamson
CEO
GAS Inc.
303 W. 3rd Street
Elk City, OK 73644
Dear Mr. Williamson:
We are writing in response to your letter received on September 17, 2020, in which you request the approval
of alternative testing procedures. The EPA’s Office of Air Quality Planning and Standards (OAQPS) is the
delegated authority for consideration of major alternatives to test methods and procedures as set forth in 40
CFR parts 60 and 63 under which your request must be addressed. GAS Inc. is requesting a change to one of
the test methods, ASTM D6348-03, used for conducting performance tests to determine compliance under
40 CFR part 60, Subpart JJJJ – Standards of Performance for Stationary Spark Ignition Internal Combustion
Engines (Subpart JJJJ) and 40 CFR part 63, Subpart ZZZZ – National Emissions Standards for Hazardous
Air Pollutants for Performance for Stationary Reciprocating Internal Combustion Engines (Subpart ZZZZ).
The change being requested will be used to check detector linearity of the Fourier Transform Infrared (FTIR)
instrumentation used to conduct this method. Specifically, you are requesting that the procedures of section
8.3.3 of Method 320 (40 CFR part 60, Appendix A), another FTIR-based method allowed under Subparts
JJJJ and ZZZZ, be used in lieu of section A6.4.1 of ASTM D6348-03 when conducting testing using ASTM
D6348-03 under 40 CFR part 60, Subpart JJJJ and 40 CFR part 63, Subpart ZZZZ.
In your request, you state that this alternative linearity check procedure will produce consistent results when
utilizing either Method 320 or ASTM D6348-03. Additionally, some FTIR instrumentation does not allow
for reducing the size of the aperture in the instrument and, thus, it would not be feasible to properly conduct
the entirety of the ASTM D6348-03 method in its current form using such an instrument.
Based on our understanding of FTIR instrument principles and recognition that the requested alternative
determination of detector linearity is both technically sound and contained within Method 320, we are
approving the requested change. We believe that this alternative is acceptable for use for use in testing all
engines subject to 40 CFR part 60 Subpart JJJJ and 40 CFR part 63, Subpart ZZZZ. Also, we will post this
letter as ALT-141 on EPA’s website (at www.epa.gov/emc/broadly-applicable-approved-alternative-
testmethods) to announce that our approval of this alternative test method is broadly applicable to engines for
the purposes of meeting Subparts JJJJ and ZZZZ.
March 15, 2021
Sincerely,
Steffan M. Johnson, Group Leader
Measurement Technology Group
If you should have any questions or require further information regarding this approval, please contact David
Nash of my staff at 919-541-9425 or email at [e-mail].

2.0 Sampling System
The sampling system used consisted of a Stainless steel probe, heated Teflon line, gas conditioning
system, and a Gasmet model DX4000 FTIR analyzer. The gas conditioning system used was a Gasmet
Personal Sampling System with a Zirconium Oxide oxygen sensor.
3.0 Methods Used
This extractive FTIR based field test method is used to quantify gas phase concentrations of multiple target
analytes (CO, NOX, CH2O, & VOC's) from stationary source effluent. Because an FTIR analyzer is
potentially capable of analyzing hundreds of compounds, this test method is not analyte or source specific.
The analytes, detection levels, and data quality objectives are expected to change for any particular testing
situation. It is the responsibility of the tester to define the target analytes, the associated detection limits for
those analytes in the particular source effluent, and the required data quality objectives for each specific
test program. Provisions are included in this test method that require the tester to determine critical
sampling system and instrument operational parameters, and for the conduct of QA/QC procedures.
Testers following this test method will generate data that will allow an independent observer to verify the
valid collection, identification, and quantification of the subject target analytes.
EPA Method 1 & 1A
EPA Method 2 & 2C
EPA Method 3A
The purpose of the method is to provide guidance for the selection of sampling ports and traverse points at
which sampling for air pollutants will be performed pursuant to regulations set forth in this part.
This method is applicable for the determination of the average velocity and the volumetric flow rate of a gas
stream. The average gas velocity in a stack is determined from the gas density and from measurement of
the average velocity head with a standard pitot tube. Velocity readings are taken from each stack at 16
separate traverse points (Table 6.1) and used to determine the engines mass emissions rate, calculated
utilizing the formulas seen in section 7.0 of this report.
This is a procedure for measuring oxygen (O2) and carbon dioxide (CO2) in stationary source emissions
using a continuous instrumental analyzer. Quality assurance and quality control requirements are included
to assure that the tester collects data of known quality. Documentation to these specific requirements for
equipment, supplies, sample collection and analysis, calculations, and data analysis will be included.

8.1 Calibration error test; how do I confirm my analyzer calibration is correct? After the tester has assembled, prepared and calibrated the
sampling system and analyzer, they conduct a 3-point analyzer calibration error test before the first run and again after any failed system bias test or
failed drift test. They then introduce the low-, mid-, and high-level calibration gases sequentially in direct calibration mode. At each calibration gas level
(low, mid, and high) the calibration error must be within ± 2.0 percent of the calibration span.
8.0 Oxygen Calibration
8.2 Initial system bias and system calibration error checks. Before sampling begins, it is determined whether the high- level or mid-level
calibration gas best approximates the emissions and it is used as the upscale gas. The upscale gas is introduced at the probe upstream of all sample-
conditioning components in system calibration mode.
8.3 Post-run system bias check and drift assessment - confirming that each sample collected is valid. Sampling may be performed for multiple
runs before performing the post-run bias or system calibration error check provided this test is passed at the conclusion of the group of runs. A failed
final test in this case will invalidate all runs subsequent to the last passed test.
(1) Next, zero gas is introduced as described above. The response must be within 0.5 percent of the upscale gas concentration.
(2) Low-level gas reading is observed until it has reached a final, stable value and the results are recorded. The measurement system will be
operated at the normal sampling rate during all system bias checks.
(3) If the initial system bias specification is not met, corrective action is taken. The applicable calibration error test from Section 8.2.3 of EPA
Method 7E is repeated along with the initial system bias check until acceptable results are achieved, after which sampling will begin. The pre-
and post-run system bias must be within ± 5.0 percent of the calibration span for the low-level and upscale calibration gases.
(1) If the post-run system bias check is not passed, then the run is invalid. The problem is then diagnosed and fixed, then another calibration
error test and system bias is passed before repeating the run.
(2) After each run, the low-level and upscale drift is calculated, using Equation 7E–4 in Section 12.5 from EPA Method 7E. If the post-run low-
and upscale bias checks are passed, but the low-or upscale drift exceeds the specification in Section 13.3, the run data are valid, but a 3-point
calibration error test and a system bias check must be performed and passed prior to additional testing.

Method 7E 3.4 To the extent practicable, the measured emissions should be between

cases of low concentration measurements or testing for compliance with an emission
limit when emissions are substantially less than the limit.

The test quality objectives completed for the emissions test are demonstrated throughout Annexes 1, 2, 3,
4, 5, 6, 7 & 8 as layed out per ASTM D6348-03. All reference methods, pre-test and post test procedures
were within acceptable limits. Data generated during the pre-test and post-test procedures are
summarized below in order of the distinctive Annex.
Three 60 minute test runs were performed. The final analyte concentrations are the average of each test
run. Data was taken at 60 second intervals. Each 60 second measurement was the average of 600 scans.
Propane is used as the surrogate compound for the Annex 5 Spiking Technique due to Propane being the
VOC that is most commonly found in the combustion process of natural gas.  Additionally, the molecular
weight of Propane coincides with with molecular weight of VOC's per the EPA.

Mr. Jordan Williamson
CEO
GAS Inc.
303 W. 3rd Street
Elk City, OK 73644
Dear Mr. Williamson:
We are writing in response to your letter received on September 17, 2020, in which you request the approval
of alternative testing procedures. The EPA’s Office of Air Quality Planning and Standards (OAQPS) is the
delegated authority for consideration of major alternatives to test methods and procedures as set forth in 40
CFR parts 60 and 63 under which your request must be addressed. GAS Inc. is requesting a change to one of
the test methods, ASTM D6348-03, used for conducting performance tests to determine compliance under
40 CFR part 60, Subpart JJJJ – Standards of Performance for Stationary Spark Ignition Internal Combustion
Engines (Subpart JJJJ) and 40 CFR part 63, Subpart ZZZZ – National Emissions Standards for Hazardous
Air Pollutants for Performance for Stationary Reciprocating Internal Combustion Engines (Subpart ZZZZ).
The change being requested will be used to check detector linearity of the Fourier Transform Infrared (FTIR)
instrumentation used to conduct this method. Specifically, you are requesting that the procedures of section
8.3.3 of Method 320 (40 CFR part 60, Appendix A), another FTIR-based method allowed under Subparts
JJJJ and ZZZZ, be used in lieu of section A6.4.1 of ASTM D6348-03 when conducting testing using ASTM
D6348-03 under 40 CFR part 60, Subpart JJJJ and 40 CFR part 63, Subpart ZZZZ.
In your request, you state that this alternative linearity check procedure will produce consistent results when
utilizing either Method 320 or ASTM D6348-03. Additionally, some FTIR instrumentation does not allow
for reducing the size of the aperture in the instrument and, thus, it would not be feasible to properly conduct
the entirety of the ASTM D6348-03 method in its current form using such an instrument.
Based on our understanding of FTIR instrument principles and recognition that the requested alternative
determination of detector linearity is both technically sound and contained within Method 320, we are
approving the requested change. We believe that this alternative is acceptable for use for use in testing all
engines subject to 40 CFR part 60 Subpart JJJJ and 40 CFR part 63, Subpart ZZZZ. Also, we will post this
letter as ALT-141 on EPA’s website (at www.epa.gov/emc/broadly-applicable-approved-alternative-
testmethods) to announce that our approval of this alternative test method is broadly applicable to engines for
the purposes of meeting Subparts JJJJ and ZZZZ.
March 15, 2021
Sincerely,
Steffan M. Johnson, Group Leader
Measurement Technology Group
If you should have any questions or require further information regarding this approval, please contact David
Nash of my staff at 919-541-9425 or email at [e-mail].

2.0 Sampling System
The sampling system used consisted of a Stainless steel probe, heated Teflon line, gas conditioning
system, and a Gasmet model DX4000 FTIR analyzer. The gas conditioning system used was a Gasmet
Personal Sampling System with a Zirconium Oxide oxygen sensor.
3.0 Methods Used
This extractive FTIR based field test method is used to quantify gas phase concentrations of multiple target
analytes (CO, NOX, CH2O, & VOC's) from stationary source effluent. Because an FTIR analyzer is
potentially capable of analyzing hundreds of compounds, this test method is not analyte or source specific.
The analytes, detection levels, and data quality objectives are expected to change for any particular testing
situation. It is the responsibility of the tester to define the target analytes, the associated detection limits for
those analytes in the particular source effluent, and the required data quality objectives for each specific
test program. Provisions are included in this test method that require the tester to determine critical
sampling system and instrument operational parameters, and for the conduct of QA/QC procedures.
Testers following this test method will generate data that will allow an independent observer to verify the
valid collection, identification, and quantification of the subject target analytes.
EPA Method 1 & 1A
EPA Method 2 & 2C
EPA Method 3A
The purpose of the method is to provide guidance for the selection of sampling ports and traverse points at
which sampling for air pollutants will be performed pursuant to regulations set forth in this part.
This method is applicable for the determination of the average velocity and the volumetric flow rate of a gas
stream. The average gas velocity in a stack is determined from the gas density and from measurement of
the average velocity head with a standard pitot tube. Velocity readings are taken from each stack at 16
separate traverse points (Table 6.1) and used to determine the engines mass emissions rate, calculated
utilizing the formulas seen in section 7.0 of this report.
This is a procedure for measuring oxygen (O2) and carbon dioxide (CO2) in stationary source emissions
using a continuous instrumental analyzer. Quality assurance and quality control requirements are included
to assure that the tester collects data of known quality. Documentation to these specific requirements for
equipment, supplies, sample collection and analysis, calculations, and data analysis will be included.

8.1 Calibration error test; how do I confirm my analyzer calibration is correct? After the tester has assembled, prepared and calibrated the
sampling system and analyzer, they conduct a 3-point analyzer calibration error test before the first run and again after any failed system bias test or
failed drift test. They then introduce the low-, mid-, and high-level calibration gases sequentially in direct calibration mode. At each calibration gas level
(low, mid, and high) the calibration error must be within ± 2.0 percent of the calibration span.
8.0 Oxygen Calibration
8.2 Initial system bias and system calibration error checks. Before sampling begins, it is determined whether the high- level or mid-level
calibration gas best approximates the emissions and it is used as the upscale gas. The upscale gas is introduced at the probe upstream of all sample-
conditioning components in system calibration mode.
8.3 Post-run system bias check and drift assessment - confirming that each sample collected is valid. Sampling may be performed for multiple
runs before performing the post-run bias or system calibration error check provided this test is passed at the conclusion of the group of runs. A failed
final test in this case will invalidate all runs subsequent to the last passed test.
(1) Next, zero gas is introduced as described above. The response must be within 0.5 percent of the upscale gas concentration.
(2) Low-level gas reading is observed until it has reached a final, stable value and the results are recorded. The measurement system will be
operated at the normal sampling rate during all system bias checks.
(3) If the initial system bias specification is not met, corrective action is taken. The applicable calibration error test from Section 8.2.3 of EPA
Method 7E is repeated along with the initial system bias check until acceptable results are achieved, after which sampling will begin. The pre-
and post-run system bias must be within ± 5.0 percent of the calibration span for the low-level and upscale calibration gases.
(1) If the post-run system bias check is not passed, then the run is invalid. The problem is then diagnosed and fixed, then another calibration
error test and system bias is passed before repeating the run.
(2) After each run, the low-level and upscale drift is calculated, using Equation 7E–4 in Section 12.5 from EPA Method 7E. If the post-run low-
and upscale bias checks are passed, but the low-or upscale drift exceeds the specification in Section 13.3, the run data are valid, but a 3-point
calibration error test and a system bias check must be performed and passed prior to additional testing.

cases of low concentration measurements or testing for compliance with an emission
limit when emissions are substantially less than the limit.

Annex 1.2
The test quality objectives completed for the emissions test are demonstrated throughout Annexes 1, 2, 3,
4, 5, 6, 7 & 8 as layed out per ASTM D6348-03. All reference methods, pre-test and post test procedures
were within acceptable limits. Data generated during the pre-test and post-test procedures are
summarized below in order of the distinctive Annex.
Three 60 minute test runs were performed. The final analyte concentrations are the average of each test
run. Data was taken at 60 second intervals. Each 60 second measurement was the average of 600 scans.
Propane is used as the surrogate compound for the Annex 5 Spiking Technique due to Propane being the
VOC that is most commonly found in the combustion process of natural gas.  Additionally, the molecular
weight of Propane coincides with with molecular weight of VOC's per the EPA.

Mr. Jordan Williamson
CEO
GAS Inc.
303 W. 3rd Street
Elk City, OK 73644
Dear Mr. Williamson:
We are writing in response to your letter received on September 17, 2020, in which you request the approval
of alternative testing procedures. The EPA’s Office of Air Quality Planning and Standards (OAQPS) is the
delegated authority for consideration of major alternatives to test methods and procedures as set forth in 40
CFR parts 60 and 63 under which your request must be addressed. GAS Inc. is requesting a change to one of
the test methods, ASTM D6348-03, used for conducting performance tests to determine compliance under
40 CFR part 60, Subpart JJJJ – Standards of Performance for Stationary Spark Ignition Internal Combustion
Engines (Subpart JJJJ) and 40 CFR part 63, Subpart ZZZZ – National Emissions Standards for Hazardous
Air Pollutants for Performance for Stationary Reciprocating Internal Combustion Engines (Subpart ZZZZ).
The change being requested will be used to check detector linearity of the Fourier Transform Infrared (FTIR)
instrumentation used to conduct this method. Specifically, you are requesting that the procedures of section
8.3.3 of Method 320 (40 CFR part 60, Appendix A), another FTIR-based method allowed under Subparts
JJJJ and ZZZZ, be used in lieu of section A6.4.1 of ASTM D6348-03 when conducting testing using ASTM
D6348-03 under 40 CFR part 60, Subpart JJJJ and 40 CFR part 63, Subpart ZZZZ.
In your request, you state that this alternative linearity check procedure will produce consistent results when
utilizing either Method 320 or ASTM D6348-03. Additionally, some FTIR instrumentation does not allow
for reducing the size of the aperture in the instrument and, thus, it would not be feasible to properly conduct
the entirety of the ASTM D6348-03 method in its current form using such an instrument.
Based on our understanding of FTIR instrument principles and recognition that the requested alternative
determination of detector linearity is both technically sound and contained within Method 320, we are
approving the requested change. We believe that this alternative is acceptable for use for use in testing all
engines subject to 40 CFR part 60 Subpart JJJJ and 40 CFR part 63, Subpart ZZZZ. Also, we will post this
letter as ALT-141 on EPA’s website (at www.epa.gov/emc/broadly-applicable-approved-alternative-
testmethods) to announce that our approval of this alternative test method is broadly applicable to engines for
the purposes of meeting Subparts JJJJ and ZZZZ.
March 15, 2021
Sincerely,
Steffan M. Johnson, Group Leader
Measurement Technology Group
If you should have any questions or require further information regarding this approval, please contact David
Nash of my staff at 919-541-9425 or email at [e-mail].
