All stack diameters, depths, widths, upstream and downstream disturbance distances and nipple lengths will be
measured on site with an EPA Method 1 verification measurement provided by the Field Team Leader. These
measurements will be included in the test report.
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 will be selected in accordance with U.S. EPA
Reference Test Method 1. To determine the minimum number of traverse points, the upstream and downstream
distances will be equated into equivalent diameters and compared to Figure 1-1 and Figure 1-2 in U.S. EPA
Reference Test Method 1

Full velocity traverses will be 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 will consist of a pitot tube and inclined manometer. The stack gas temperature will be measured with a K-
type thermocouple and pyrometer.
3.2 U.S. EPA Reference Test Method 3/3A – Oxygen/Carbon Dioxide
The oxygen (O2) and carbon dioxide (CO2) testing will be conducted in accordance with U.S. EPA Reference Test
Method 3/3A. One (1) integrated Tedlar bag sample will be collected during each test run. The bags will be
collected from the positive pressure side of the sample pump and conditioner. They will be collected through a
manifold with a restriction (either rotometer or critical orifice) to ensure even filling throughout the course of the
run. Samples will be concurrent with the test runs. The bag samples will be analyzed on site with a gas analyzer.
The remaining stack gas constituent will be assumed to be nitrogen for the stack gas molecular weight
determination. The quality control measures are described in Section 3.9.

AST-2024-2436-002 Chevron – North Salt Lake, UT Page 3-2

3.3 U.S. EPA Reference Test Method 3A – Oxygen/Carbon Dioxide
The oxygen (O2) and carbon dioxide (CO2) testing will be conducted in accordance with U.S. EPA Reference Test
Method 3A. Data will be collected online and reported in one-minute averages. The sampling system will consist
of a stainless steel probe, Teflon sample line(s), gas conditioning system and the identified gas analyzer. The gas
conditioning system will be a non-contact condenser used to remove moisture from the stack gas. If an unheated
Teflon sample line is used, then a portable non-contact condenser will be placed in the system directly after the
probe. Otherwise, a heated Teflon sample line will be used. The quality control measures are described in Section
3.10.
3.4 U.S. EPA Reference Test Method 4 – Moisture Content
The stack gas moisture content will be determined in accordance with U.S. EPA Reference Test Method 4. The gas
conditioning train will consist of a series of chilled impingers. Prior to testing, each impinger will be filled with a
known quantity of water or silica gel. Each impinger will be analyzed gravimetrically before and after each test run
on the same analytical balance to determine the amount of moisture condensed.
3.5 U.S. EPA Reference Test Method 5F – Non-Sulfate Particulate Matter
The non-sulfate filterable particulate matter sampling will be conducted in accordance with U.S. EPA Reference
Test Method 5F. The complete sampling system will consist of a siliconized nozzle, heated stainless steel-lined
probe, pre-weighed heated quartz filter, gas conditioning train, pump and calibrated dry gas meter. The gas
conditioning train will consist of four (4) chilled impingers – the first and second will contain 100 mL of H2O, the
third impinger will be initially empty and the fourth will contain 200-300 grams of silica gel. The probe liner and
filter heating systems will be maintained at a temperature of 120 ± 14°C (248 ±25°F) and the impinger temperature
will be maintained at 20°C (68°F) or less throughout the testing.

Following the completion of each test run, the sampling train will be leak checked at a vacuum pressure greater than or
equal to the highest vacuum pressure observed during the run, and the contents of the impingers will be measured for
moisture gain. The probe and nozzle will be rinsed and brushed six (6) times with water to remove any adhering
particulate matter. This rinse will be recovered in Container 2. The front half of the filter holder will be rinsed three (3)
times with water and this rinse will be added to Container 2. The pre-weighed quartz filter will be carefully removed and
placed in Container 1. All containers will be sealed, labeled and liquid levels marked for transport to the identified
laboratory.
3.6 U.S. EPA Reference Test Method 7E – Nitrogen Oxides
The nitrogen oxides (NOx) testing will be conducted in accordance with U.S. EPA Reference Test Method 7E. Data
will be collected online and reported in one-minute averages. The sampling system will consist of a stainless steel
probe, Teflon sample line(s), gas conditioning system and the identified gas analyzer. The gas conditioning system
will be a non-contact condenser used to remove moisture from the stack gas. If an unheated Teflon sample line is
used, then a portable non-contact condenser will be placed in the system directly after the probe. Otherwise, a
heated Teflon sample line will be used. The quality control measures are described in Section 3.10.
3.7 U.S. EPA Reference Test Method 19 – Mass Emission Factors
The pollutant concentrations will be converted to mass emission factors (lb/MMBtu) using procedures outlined in
U.S. EPA Reference Test Method 19. The published dry O2 based fuel factor (F-Factor) of 8,710 dscf/MMBtu for
natural gas will be used in the calculations.

3.8 U.S. EPA Reference Test Method 205 – Gas Dilution System Certification
A calibration gas dilution system field check will be conducted in accordance with U.S. EPA Reference Method
205. An initial three (3) point calibration will be 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 will be utilized to force
the dilution system to perform two dilutions on each mass flow controller. The diluted calibration gases will be sent
directly to the analyzer, and the analyzer response recorded in an electronic field data sheet. The analyzer response
must agree within 2% of the actual diluted gas concentration. A second Protocol 1 calibration gas, with a cylinder
concentration within 10% of one of the gas divider settings described above, will be introduced directly to the
analyzer, and the analyzer response recorded in an electronic field data sheet. The cylinder concentration and the
analyzer response must agree within 2%. These steps will be repeated three (3) times.
3.9 Quality Assurance/Quality Control – U.S. EPA Reference Test Method 3/3A
Cylinder calibration gases will meet EPA Protocol 1 (+/- 2%) standards. Copies of all calibration gas certificates
will be included in the Quality Assurance/Quality Control Appendix of the report.

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

A Data Acquisition System with battery backup will be used to record the instrument response in one (1) minute
averages. The data will be continuously stored as a *.CSV file in Excel format on the hard drive of a computer. At
the completion of testing, the data will also be saved to the Alliance server. All data will be reviewed by the Field
Team Leader before leaving the facility. Once arriving at Alliance’s office, all written and electronic data will be
relinquished to the report coordinator and then a final review will be performed by the Project Manager.
3.10 Quality Assurance/Quality Control – U.S. EPA Reference Test Methods 3A and 7E
Cylinder calibration gases will meet EPA Protocol 1 (+/- 2%) standards. Copies of all calibration gas certificates
will be included in the Quality Assurance/Quality Control Appendix of the report.

Low Level gas will be introduced directly to the analyzer. After adjusting the analyzer to the Low-Level gas
concentration and once the analyzer reading is stable, the analyzer value will be recorded. This process will be
repeated for the High-Level gas. For the Calibration Error Test, Low, Mid, and High-Level calibration gases will be
sequentially introduced directly to the analyzer. The Calibration Error for each gas must be within 2.0 percent of the
Calibration Span or 0.5 ppmv/% absolute difference.

High or Mid-Level gas (whichever is closer to the stack gas concentration) will be introduced at the probe and the
time required for the analyzer reading to reach 95 percent or 0.5 ppm/% (whichever was less restrictive) of the gas
concentration will be recorded. The analyzer reading will be observed until it reaches a stable value, and this value
will be recorded. Next, Low-Level gas will be introduced at the probe and the time required for the analyzer reading
to decrease to a value within 5.0 percent or 0.5 ppm/% (whichever was less restrictive) will be recorded. If the Low-
Level gas is zero gas, the acceptable response must be 5.0 percent of the upscale gas concentration or 0.5 ppm/%
(whichever was less restrictive). The analyzer reading will be observed until it reaches a stable value, and this value

Site Specific Test Plan
Testing Methodology

AST-2024-2436-002 Chevron – North Salt Lake, UT Page 3-4

will be recorded. The measurement system response time and initial system bias will be determined from these data.
The System Bias for each gas must be within 5.0 percent of the Calibration Span or 0.5 ppmv/% absolute difference.

High or Mid-Level gas (whichever is closer to the stack gas concentration) will be introduced at the probe. After the
analyzer response is stable, the value will be recorded. Next, Low-Level gas will be introduced at the probe, and the
analyzer value will be recorded once it reaches a stable response. The System Bias for each gas must be within 5.0
percent of the Calibration Span or 0.5 ppmv/% absolute difference or the data is invalidated, and the Calibration
Error Test and System Bias must be repeated.

The Drift between pre- and post-run System Bias must be within 3 percent of the Calibration Span or 0.5 ppmv/%
absolute difference or the Calibration Error Test and System Bias must be repeated.

To determine the number of sampling points, a gas stratification check will be conducted prior to initiating testing.
The pollutant concentrations will be measured at twelve traverse points (as described in Method 1) or three points
(16.7, 50.0 and 83.3 percent of the measurement line). Each traverse point will be sampled for a minimum of twice
the system response time.

If the pollutant concentration at each traverse point do not differ more than 5% or 0.5 ppm/0.3% (whichever is less
restrictive) of the average pollutant concentration, then single point sampling will be conducted during the test runs.
If the pollutant concentration does not meet these specifications but differs less than 10% or 1.0 ppm/0.5% from the
average concentration, then three (3) point sampling will be 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 differs by more than 10% or 1.0 ppm/0.5% from the average
concentration, then sampling will be conducted at a minimum of twelve (12) traverse points. Copies of stratification
check data will be included in the Quality Assurance/Quality Control Appendix of the report.

An NO2 – NO converter check will be performed on the analyzer prior to initiating testing or at the completion of
testing. An approximately 50 ppm nitrogen dioxide cylinder gas will be introduced directly to the NOx analyzer and
the instrument response will be recorded in an electronic data sheet. The instrument response must be within +/- 10
percent of the cylinder concentration.

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

4.0 Quality Assurance Program
Alliance follows the procedures outlined in the Quality Assurance/Quality Control Management Plan to ensure the
continuous production of useful and valid data throughout the course of this test program. The QC checks and
procedures described in this section represent an integral part of the overall sampling and analytical scheme.
Adherence to prescribed procedures is quite often the most applicable QC check.
4.1 Equipment
Field test equipment is assigned a unique, permanent identification number. Prior to mobilizing for the test
program, equipment is inspected before being packed to detect equipment problems prior to arriving on site. This
minimizes lost time on the job site due to equipment failure. Occasional equipment failure in the field is
unavoidable despite the most rigorous inspection and maintenance procedures. Therefore, replacements for critical
equipment or components are brought to the job site. Equipment returning from the field is inspected before it is
returned to storage. During the course of these inspections, items are cleaned, repaired, reconditioned and
recalibrated where necessary.

Calibrations are conducted in a manner, and at a frequency, which meets or exceeds U.S. EPA specifications. The
calibration procedures outlined in the U.S. EPA Methods, and those recommended within the Quality Assurance
Handbook for Air Pollution Measurement Systems: Volume III (EPA-600/R-94/038c, September 1994) are utilized.
When these methods are inapplicable, methods such as those prescribed by the American Society for Testing and
Materials (ASTM) or other nationally recognized agency may be used. Data obtained during calibrations is checked
for completeness and accuracy. Copies of calibration forms are included in the report.

The following sections elaborate on the calibration procedures followed by Alliance for these items of equipment.

• Dry Gas Meter and Orifice. A full meter calibration using critical orifices as the calibration standard is
conducted at least semi-annually, more frequently if required. The meter calibration procedure determines
the meter correction factor (Y) and the meter’s orifice pressure differential (ΔH@). Alliance uses approved
Alternative Method 009 as a post-test calibration check to ensure that the correction factor has not changed
more than 5% since the last full meter calibration. This check is performed after each test series.
• Pitot Tubes and Manometers. Type-S pitot tubes that meet the geometric criteria required by U.S. EPA
Reference Test Method 2 are assigned a coefficient of 0.84 unless a specific coefficient has been
determined from a wind tunnel calibration. If a specific coefficient from a wind tunnel calibration has been
obtained that coefficient will be used in lieu of 0.84. Standard pitot tubes that meet the geometric criteria
required by U.S. EPA Reference Test Method 2 are assigned a coefficient of 0.99. Any pitot tubes not
meeting the appropriate geometric criteria are discarded and replaced. Manometers are verified to be level
and zeroed prior to each test run and do not require further calibration.
• Temperature Measuring Devices. All thermocouple sensors mounted in Dry Gas Meter Consoles are
calibrated semi-annually with a NIST-traceable thermocouple calibrator (temperature simulator) and
verified during field use using a second NIST-traceable meter. NIST-traceable thermocouple calibrators
are calibrated annually by an outside laboratory.
• Nozzles. Nozzles are measured three (3) times prior to initiating sampling with a caliper. The maximum
difference between any two (2) dimensions is 0.004 in.
• Digital Calipers. Calipers are calibrated annually by Alliance by using gage blocks that are calibrated
annually by an outside laboratory.

• Barometer. The barometric pressure is obtained from a nationally recognized agency or a calibrated
barometer. Calibrated barometers are checked prior to each field trip against a mercury barometer. The
barometer is acceptable if the values agree within ± 2 percent absolute. Barometers not meeting this
requirement are adjusted or taken out of service.
• Balances and Weights. Balances are calibrated annually by an outside laboratory. A functional check is
conducted on the balance each day it is use in the field using a calibration weight. Weights are re-certified
every two (2) years by an outside laboratory or internally. If conducted internally, they are weighed on a
NIST traceable balance. If the weight does not meet the expected criteria, they are replaced.
• Other Equipment. A mass flow controller calibration is conducted on each Environics system annually
following the procedures in the Manufacturer’s Operation manual. A methane/ethane penetration factor
check is conducted on the total hydrocarbon analyzers equipped with non-methane cutters every six (6)
months following the procedures in 40 CFR 60, Subpart JJJJ. Other equipment such as probes, umbilical
lines, cold boxes, etc. are routinely maintained and inspected to ensure that they are in good working order.
They are repaired or replaced as needed.
4.2 Field Sampling
Field sampling will be done in accordance with the Standard Operating Procedures (SOP) for the applicable test
method(s). General QC measures for the test program include:
• Cleaned glassware and sample train components will be sealed until assembly.
• Sample trains will be leak checked before and after each test run.
• Appropriate probe, filter and impinger temperatures will be maintained.
• The sampling port will be sealed to prevent air from leaking from the port.
• Dry gas meter, ΔP, ΔH, temperature and pump vacuum data will be recorded during each sample point.
• An isokinetic sampling rate of 90-110% will be maintained, as applicable.
• All raw data will be maintained in organized manner.
• All raw data will be reviewed on a daily basis for completeness and acceptability.
4.3 Analytical Laboratory
Analytical laboratory selection for sample analyses is based on the capabilities, certifications and accreditations that
the laboratory possesses. An approved analytical laboratory subcontractor list is maintained with a copy of the
certificate and analyte list as evidence of compliance. Alliance assumes responsibility to the client for the
subcontractor’s work. Alliance maintains a verifiable copy of the results with chain of custody documentation.
