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].

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.

D6348 Annexes 1. Test Plan Requirements
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].
