3.1 U.S. EPA Reference Test Methods 1 and 2 – Sampling/Traverse Points and Volumetric Flow Rate
The sampling location and number of traverse (sampling) points were selected in accordance with U.S. EPA
Reference Test Method 1. To determine the minimum number of traverse points, the upstream and downstream
distances were equated into equivalent diameters and compared to Figure 1-2 in U.S. EPA Reference Test Method 1.

Full velocity traverses were conducted in accordance with U.S. EPA Reference Test Method 2 to determine the
average stack gas velocity pressure, static pressure and temperature. The velocity and static pressure measurement
system consisted of a pitot tube and inclined manometer. The stack gas temperature was measured with a K-type
thermocouple and pyrometer.

Stack gas velocity pressure and temperature readings were recorded during each test run. The data collected was
utilized to calculate the volumetric flow rate in accordance with U.S. EPA Reference Test Method 2.
3.2 U.S. EPA Reference Test Method 3A – Oxygen/Carbon Dioxide
The oxygen (O2) and carbon dioxide (CO2) testing was conducted in accordance with U.S. EPA Reference Test
Method 3A. Data was collected online and reported in one-minute averages. The sampling system consisted of a
stainless-steel probe, Teflon sample line(s), gas conditioning system and the identified gas analyzer. The gas
conditioning system was a non-contact condenser used to remove moisture from the stack gas. If an unheated
Teflon sample line was used, then a portable non-contact condenser was placed in the system directly after the
probe. Otherwise, a heated Teflon sample line was used. The quality control measures are described in Section 3.6.
3.3 U.S. EPA Reference Test Method 25A – Total Hydrocarbons
The total hydrocarbons (THC) testing was conducted in accordance with U.S. EPA Reference Test Method 25A. Data
was collected online and reported in one-minute averages. The sampling system consisted of a stainless-steel probe,
heated Teflon sample line(s) and the identified gas analyzer. The quality control measures are described in Section 3.7.
3.4 U.S. EPA Reference Test Method 320 – Moisture Content, Methane & Ethane
The moisture content and concentrations of methane and ethane were determined in accordance with U.S. EPA
Reference Test Method 320. Each source gas stream was extracted at a constant rate through a heated probe, heated filter
and heated sample line and analyzed with a MKS MultiGas 2030 FTIR operated by a portable computer. The computer

has FTIR spectra of calibration gases stored on the hard drive. These single component calibration spectra are used to
analyze the measured sample spectra. The gas components to be measured were selected from the spectra library and
incorporated into the analytical method. The signal amplitude, linearity, and signal to noise ratio were measured and
recorded to document analyzer performance. A leak check was performed on the sample cell. The instrument path length
was verified using ethylene as the Calibration Transfer Standard. Dynamic spiking was performed using a certified
standard of the target compound or appropriate surrogate in nitrogen with sulfur hexafluoride blended as a tracer to
calculate the dilution factor. All test spectra, interferograms, and analytical method information are recorded and stored
with the calculated analytical results. The quality control measures are described in Section 3.8.
3.5 U.S. EPA Reference Test Method 205 – Gas Dilution System Certification
A calibration gas dilution system field check was conducted in accordance with U.S. EPA Reference Method 205.
An initial three (3) point calibration was conducted, using individual Protocol 1 gases, on the analyzer used to
complete the dilution system field check. Multiple dilution rates and total gas flow rates were utilized to force the
dilution system to perform two dilutions on each mass flow controller. The diluted calibration gases were sent
directly to the analyzer, and the analyzer response recorded in an electronic field data sheet. A mid-level supply gas,
with a cylinder concentration within 10% of one of the gas divider settings described above, was introduced directly
to the analyzer, and the analyzer response recorded in an electronic field data sheet. The cylinder concentration and
the analyzer response agreed within 2%. These steps were repeated three (3) times. The average analyzer response
agreed within 2% of the predicted gas concentration. No single injection differed more than 2% from the average
instrument response for that dilution. Copies of the Method 205 data can be found in the Quality Assurance/Quality
Control Appendix.
3.6 Quality Assurance/Quality Control – U.S. EPA Reference Test Method 3A
Cylinder calibration gases used met EPA Protocol 1 (+/- 2%) standards. Copies of all calibration gas certificates can
be found in the Quality Assurance/Quality Control Appendix.

Low Level gas was introduced directly to the analyzer. After adjusting the analyzer to the Low-Level gas
concentration and once the analyzer reading was stable, the analyzer value was recorded. This process was repeated
for the High-Level gas. For the Calibration Error Test, Low, Mid, and High Level calibration gases were
sequentially introduced directly to the analyzer. All values were within 2.0 percent of the Calibration Span or 0.5%
absolute difference.

High or Mid-Level gas (whichever was closer to the stack gas concentration) was introduced at the probe and the
time required for the analyzer reading to reach 95 percent or 0.5% (whichever was less restrictive) of the gas
concentration was recorded. The analyzer reading was observed until it reached a stable value, and this value was
recorded. Next, Low Level gas was introduced at the probe and the time required for the analyzer reading to
decrease to a value within 5.0 percent or 0.5% (whichever was less restrictive) was recorded. If the Low-Level gas
was zero gas, the response was 0.5% or 5.0 percent of the upscale gas concentration (whichever was less restrictive).
The analyzer reading was observed until it reached a stable value and this value was recorded. The measurement
system response time and initial system bias were determined from these data. The System Bias was within 5.0
percent of the Calibration Span or 0.5% absolute difference.

High or Mid-Level gas (whichever was closer to the stack gas concentration) was introduced at the probe. After the
analyzer response was stable, the value was recorded. Next, Low Level gas was introduced at the probe, and the
analyzer value recorded once it reached a stable response. The System Bias was within 5.0 percent of the

Calibration Span or 0.5% absolute difference or the data was invalidated and the Calibration Error Test and System
Bias were repeated.

Drift between pre- and post-run System Bias was within 3 percent of the Calibration Span or 0.5% absolute
difference. If the drift exceeded 3 percent or 0.5%, the Calibration Error Test and System Bias were repeated.

To determine the number of sampling points, a gas stratification check was conducted prior to initiating testing. The
pollutant concentrations were measured at three points (16.7, 50.0 and 83.3 percent of the measurement line). Each
traverse point was sampled for a minimum of twice the system response time.

If the diluent concentration at each traverse point did not differ more than 5 percent or 0.3% (whichever was less
restrictive) of the average pollutant concentration, then single point sampling was conducted during the test runs. If
the pollutant concentration did not meet these specifications but differed less than 10 percent or 0.5% from the
average concentration, then three (3) point sampling was conducted (stacks less than 7.8 feet in diameter - 16.7, 50.0
and 83.3 percent of the measurement line; stacks greater than 7.8 feet in diameter – 0.4, 1.0, and 2.0 meters from the
stack wall). If the pollutant concentration differed by more than 10 percent or 0.5% from the average concentration,
then sampling was conducted at a minimum of twelve (12) traverse points. Copies of stratification check data can
be found in the Quality Assurance/Quality Control Appendix.

A Data Acquisition System with battery backup was used to record the instrument response in one (1) minute
averages. The data was continuously stored as a *.CSV file in Excel format on the hard drive of a computer. At the
completion of testing, the data was also saved to the Alliance server. All data was reviewed by the Field Team
Leader before leaving the facility. Once arriving at Alliance’s office, all written and electronic data was
relinquished to the report coordinator and then a final review was performed by the Project Manager.
3.7 Quality Assurance/Quality Control – U.S. EPA Reference Test Method 25A
Cylinder calibration gases used met EPA Protocol 1 (+/- 2%) standards. Copies of all calibration gas certificates can
be found in the Quality Assurance/Quality Control Appendix.

Within two (2) hours prior to testing, zero gas was introduced through the sampling system to the analyzer. After
adjusting the analyzer to the Zero gas concentration and once the analyzer reading was stable, the analyzer value
was recorded. This process was repeated for the High-Level gas, and the time required for the analyzer reading to
reach 95 percent of the gas concentration was recorded to determine the response time. Next, Low and Mid-Level
gases were introduced through the sampling system to the analyzer, and the response was recorded when it was
stable. All values were less than +/- 5 percent of the calibration gas concentrations.

Mid-Level gas was introduced through the sampling system. After the analyzer response was stable, the value was
recorded. Next, Zero gas was introduced through the sampling system, and the analyzer value recorded once it
reached a stable response. The Analyzer Drift was less than +/- 3 percent of the span value.

A Data Acquisition System with battery backup was used to record the instrument response in one (1) minute
averages. The data was continuously stored as a *.CSV file in Excel format on the hard drive of a computer. At the
completion of testing, the data was also saved to the Alliance server. All data was reviewed by the Field Team
Leader before leaving the facility. Once arriving at Alliance’s office, all written and electronic data was
relinquished to the report coordinator and then a final review was performed by the Project Manager.

3.8 Quality Assurance/Quality Control – U.S. EPA Reference Method 320
EPA Protocol 1 Calibration Gases – Cylinder calibration gases used met EPA Protocol 1 (+/- 2%) standards. Copies
of all calibration gas certificates can be found in the Quality Assurance/Quality Control Appendix.

After providing ample time for the FTIR to reach the desired temperature and to stabilize, zero gas (nitrogen) was
introduced directly to the instrument sample port. While flowing nitrogen the signal amplitude was recorded, a
background spectra was taken, a linearity check was performed and recorded, the peak to peak noise and the root
mean square in the spectral region of interest was measured and a screenshot was recorded.

Following the zero gas checks, room air was pulled through the sample chamber and the line width and resolution
was verified to be at 1879 cm-1, the peak position was entered and the FWHH was recorded (screenshot).
Following these checks, another background spectra was recorded, and the calibration transfer standard (CTS) was
introduced directly to the instrument sample port. The CTS instrument recovery was recorded, and the instrument
mechanical response time was measured.

Next, stack gas was introduced to the FTIR through the sampling system and several scans were taken until a stable
reading was achieved. The native concentration of our target or surrogate spiking analyte was recorded. Spike gas
was introduced to the sampling system at a constant flow rate ≤ 10% of the total sample flow rate and a
corresponding dilution ratio was calculated along with a system response time. Matrix spike recovery spectra were
recorded and were within the ± 30% of the calculated value of the spike concentration that the method requires.

The matrix spike recovery was conducted once at the beginning of the testing and the CTS recovery procedures
were repeated following each test run. The corresponding values were recorded.

This is to certify the gases referenced have been calibrated/tested, and verified to meet the defined specifications. This
calibration/test was performed using Gases or Scales that are traceable through National Institute of Standards and
Technology (NIST) to the International System of Units (SI). The basis of compliance stated is a comparison of the
measurement parameters to the specified or required calibration/testing process. The expanded uncertainties use a coverage
factor of k=2 to approximate the 95% confidence level of the measurement, unless otherwise noted. This calibration certificate
applies only to the item described and shall not be reproduced other than in full, without written approval from Red Ball
Technical Gas Services. If not included, the uncertainty of calibrations are available upon request and were taken into account
when determining pass or fail.

This is to certify the gases referenced have been calibrated/tested, and verified to meet the defined specifications. This
calibration/test was performed using Gases or Scales that are traceable through National Institute of Standards and
Technology (NIST) to the International System of Units (SI). The basis of compliance stated is a comparison of the
measurement parameters to the specified or required calibration/testing process. The expanded uncertainties use a coverage
factor of k=2 to approximate the 95% confidence level of the measurement, unless otherwise noted. This calibration certificate
applies only to the item described and shall not be reproduced other than in full, without written approval from Red Ball
Technical Gas Services. If not included, the uncertainty of calibrations are available upon request and were taken into account
when determining pass or fail.

This is to certify the gases referenced have been calibrated/tested, and verified to meet the defined specifications. This
calibration/test was performed using Gases or Scales that are traceable through National Institute of Standards and
Technology (NIST) to the International System of Units (SI). The basis of compliance stated is a comparison of the
measurement parameters to the specified or required calibration/testing process. The expanded uncertainties use a
coverage factor of k=2 to approximate the 95% confidence level of the measurement, unless otherwise noted. This
calibration certificate applies only to the item described and shall not be reproduced other than in full, without written approval
from Red Ball Technical Gas Services. If not included, the uncertainty of calibrations are available upon request and were
taken into account when determining pass or fail.
