This section provides a description of the sampling and analyical procedues for each test metlod that will be
employed during the test program. All equipment, procedures and quality assurance measures necessary for the
completion of the test progrilm meet or exceed the specifications of each relevant test method. The emission testing
program will be conducted in accordance with the test methods listed in Table 3- l .
Table 3-l: Source Testing Methodology
All stack diameters, depths, widths, upstream and downstream disturbance distances and nipple lengths will be
measrued on site with an EPA Method I verification measurement provided by the Field Team Leader. These
measwements will be included in the test report.
3.1 U.S. EPA Reference Test Methods I 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 l. To determine the minimum number of traverse points, the upstream and downstream
distances will be equated into equivalent diameters and compared to Figure l-1 (for isokinetic sampling) and/or
Figure l-2 (measuring velocity alone) in U.S. EPA Reference Test Method l.
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.
Stack gas velocity pressure and temperature readings will be recorded during each test run. The data collected will
be utilized to calculate the volumetric flow rate in accordance with U.S. EPA Reference Test Method 2.
Stack gas velocity pressru€ and temperature readings will be recorded during each test run. The data collected will
be utilized to calculate the volumetric flow rate for comparison to the continuous emission rate monitoring system
(CERMS). The relative accuracy of the CERMS will be determined based on procedures found in 40 CFR 60,

The relative accuracy of the CO CEMS will be determined based on procedures found in 40 CFR 60, Performance
Specification 4 or 4A.
3.7 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 I gases, on the analyzer used
to complete the dilution system f,reld check. Multiple dilution rates and total gas flow rates will be utilized to force
the dilution system to perform nvo dilutions on each mass flow controller. The diluted calibration gases will be sent
directly to the analyzer, and the analyzer response will be recorded in an electronic field data sheet. A mid-level
supply gas, with a cylinder concentration within l0%o of one of the gas divider settings described above, will be
intoduced directly to the analyzer, and the analyzer response recorded in an electonic field data sheet. The
cylinder concentration and the analyzer response must agree within 2Yo. Tlrese steps will be repeated three (3)
times. The average analyzer response must agree within ZYo of the predicted gas concentation. No single injection
shall differ more than 2Yo from the average instrument response for that dilution.
3.8 Quality Assurance/Quelity Control - U.S. EPA Reference Test Methods 3A, 6C, 7E and 10
Cylinder calibration gases will meet EPA Protocol I (+/- 2%) standards. Copies of all calibration gas certificates
will be included in the Quality Assurance/Quality Contol Appendix of the report.
Low Level gas will be inhoduced directly to the analyzer. After adjusting the analyzer to the Low Level gas
concenfration 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 ppmvl%o absolute difference.
High or Mid Level gas (whichever is closer to the stack gas concenffation) will be inEoduced 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
concentation 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 ppnr/% (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 gzrs concenhation or 0.5 ppm/%
(whichever was less reskictive). The analyzer reading will be observed until it reaches a stable value and this value
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 differance.
High or Mid Level gas (whichever is closer to the stack gas concentation) will be intoduced at the probe. After the
analyzer response is stable, the value will be recorded. Next, Low Level gas will be intoduced 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.

Testins MethodolopvTECIINICAL GROUP
The thift 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 statification check will be conducted prior to initiating testing.
The pollutant concentrations will be measured at twelve traverse points (as described in Method l) or three points
(16.7, 50.0 and 83.3 percent of the measurement [ine). Each haverse 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 5o/o or 0.5 ppmlD.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 lo%o or 1.0 ppml0.5% from the
average concentration, then three (3) point sarnpling 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 l0% 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 NOz - NO converter check will be perfonned 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 electonic data sheet. The ins0rrment response must be within +/- l0
percent of the cylinder concentation.
A Data Acquisition System with battery backup will be used to record the instrument response in one (l) minute
averages. The data will be continuously stored as a *.CSV file in Excel fomrat 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
Tearn Leader before leaving the facility. Once arriving at Alliance's office, all written and electonic data will be
relinquished to the report coordinator and then a final review will be performed by the Project Manager.

Quality Assurance ProgramTEC[INICAL GROUP
4.0 Quality Assurence Program
Alliance follows the procedures outlined in the Quality Assurance/Quality Contol 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 identifrcation number. Prior to mobilizing for the test
program, equipment is inspected before being packed to detect equipmant problems prior to aniving 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
rehrmed 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 1e1 Js5ting and
Materials (ASTM) or other nationally recognized agency may be used. Data obtained during calibrations is checked
for completeness and accwacy. 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.
o Drv 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 detennines
the meter correction factor (Y) and the meter's orifice pressure differential (AH@). 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 geomekic criteria required by U.S. EPA
Reference Test Method 2 are assigned a coefficient of 0.84 unless a specific coeffrcient has been
determined from a wind tunnel calibration. If a specific coefficient from a wind tunnel calibration has been
obtained that coeflicient will be used in lieu of 0.84. Standaxd pitot tubes that meet the geometric criteria
required by U.S. EPA Reference Test Method 2 are assigred a coeffrcient 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 firrther calibration.
. Temperature Measurinq Devices. All thermocouple sensors mounted in Dry Gas Meter Consoles are
calibrated semi-annually with a MST-traceable thermocouple calibrator (temperature simulator) and
verified during field use using a second MST-traceable meter. NlST-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 0.0M in.
o Dieital Calipers. Calipers are calibrated annually by Alliance by using gage blocks that are calibrated
annually by an outside laboratory.

TECF.I NICAL GROUP Site Specifc Test Plan
Quality A s suranc e Pro gr am
Barometer. The barometric pressure is obtained from a nationally recognized agency or a calibrated
barometer. Calibrated barometers are checked prior to each field tip against a mercury barometer. The
barometer is acceptable if the values agree within a 2 percent absolute. Barometers not meeting this
requirement are adjusted or taken out ofservice.
Balances and Weiehts. 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
MST traceable balance. If the weight does not meet the expected criteria, they are replaced.
Other Eouipment. A mass flow contoller calibration is conducted on each Environics system annually
following the procedures in the Manufacturer's Operation manual. A methane/ethane penefation 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:
o Cleaned glassware and sample hain components will be sealed until assembly.
o Sample tains will be leak checked before and after each test run.
o Appropriate probe, filter and impinger temperatures will be maintained.
o The sarnpling port will be sealed to prevent air from leaking from the port.
. Dry gas meter, AP, AH, temperature and pump vacuum data will be recorded during each sarnple point.
o All raw data will be maintained in organized manner.
. All raw data will be reviewed on a daily basis for completeness and acceptability.

3.0 Testing Methodology
This section provides a description of the sampling and analytical procedures for each test method that will be
employed during the test prograrn. All equipment, procedures and quality itssurance measures necessary for the
completion of the test program meet or exceed the specifications of each relevant test method. The emission testing
progmm will be conducted in accordance with the test methods listed in Table 3-1.
Table 3-1: Source Testing Methodology
All stack diameters, depths, widths, upstream and downsfteam disturbance distances and nipple lengths will be
measured on site with an EPA Method I verification measwement provided by the Field Team Leader. These
measurements will be included in the test report.
3.1 U.S. EPA Reference Test Methods I and 2 - Sampling/Trayerse Points end Volumetric Flow Rate
The sampling location and number of traverse (sampling) points will be selected in accordance with U.S. EPA
Reference Test Method l. To determine the minimum number of haverse points, the upsheam and downstream
distances will be equated into equivalent diameters and compared to Figure l-l (for isokinetic sampling) and/or
Figure l-2 (measuring velocity alone) in U.S. EPA Reference Test Method l.
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.
Stack gas velocity pressure and temperature readings will be recorded during each test run. The data collected will
be 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 - Orygen/Carbon Dioxide

3.7 U.S. EPA Reference Test Method 205 - Gas Dilution System Certilication
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 I 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 nvo dilutions on each mass flow controller. The diluted calibration gases will be sent
directly to the analyzer, and the analyzer response will be recorded in an electronic field data sheet. A mid-level
supply gas, with a cylinder concentration within l0% of one of the gas divider settings described above, will be
introduced directly to the analyzEr, and the analyzer response recorded in an elechonic field data sheet. The
cylinder concenEation and the analyzer response must agree within 2Yo. T\ese steps will be repeated three (3)
times. The average analyzer response must agree within 2o/o of the predicted gas concentration. No single injection
shall differ more than 2Yofrom the average instnrment response for that dilution.
3.8 Quality Assurance/Quelity Control - U.S. EPA Reference Test Methods 3A, 6C, 7E and l0
Cylinder calibration gases will meet EPA Protocol | (+l- 2%) standards. Copies of all calibration gas certificates
will be included in the Quality Assurance/Quality Conffol Appendix of the report.
Low Level gas will be introduced directly to the analyzer. After adjusting the analyzer to the Low Level gas
concentation 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 inffoduced direcfly to the analyzer. The Calibration Error for each gas must be within 2.0 percent of the
Calibration Span or 0.5 ppmvl%o 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/oh (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 pprn/% (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 concenhation or 0.5 ppm/%
(whichever was less reskictive). The analyzer reading will be observed until it reaches a stable value and this value
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 intoduced at the probe. After the
analyzer response is stable, the value will be recorded. Next, Low Level gas will be intoduced 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 betwean 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 deterrnine the number of sa:npling points, a gas statification check will be conducted prior to initiating testing.
The pollutant concentrations will be measured at twelve taverse points (as described in Method l) 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 tav€rse point do not differ more than 5% or 0.5 ppm/0.3% (whichever is less
restrictive) of the average pollutant concenmtion, then single point sampling will be conducted during the test runs.
If the pollutant concentration does not meet these specifications but ditrers less than l0Yo or 1.0 pprn/0.5% from the
average concentration, then ttrree (3) point sampling will be conducted (stacks less than 7.8 feet in diameter - 16.7,
50.0 and 83.3 percant of the measurement line; stacks greater than 7.8 feet in diameter - 0.4, I .0, and 2.0 meters
from the stack wall). If the pollutant concentation differs by more than l0% or 1.0 pprn/0.5% from the average
concentation, then sarpling will be conducted at a minimum of twelve (12) taverse points. Copies of stratification
check data will be included in the Quality Assurance/Quality Connol Appendix of the report.
An NOz - NO converter check will be performed on the analyzer prior to initiating testing or at the completion of
testing. An approximately 50 ppm nibogen dioxide cylinder gas will be intoduced directly to the NOx analyzer and
the instrument response will be recorded in an electronic data sheet. The instrument response must be within +/- l0
percent of the cylinder concentration.
A Data Acquisition System with battery backup will be used to record the instrument response in one (l) 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 Progrem
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 ariving on site. This
minimizes lost time on the job site due to equipmant failure. Occasional equipment failure in the field is
unavoidable despite the most rigorous inspection and maintenance procedures. Therefore, replacemenc for critical
equipment or components are brought to the job site. Equipment returning from the field is inspected before it is
retumed 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 recogpized 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.
o 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 detemrines
the meter correction factor (Y; and the meter's orifice pressure differential (AH@). Alliance uses approved
Altemative 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.
r 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. Standaxd pitot tubes that meet the geometric criteria
required by U.S. EPA Reference Test Method 2 are assigned a coeffrcient of 0.99. Any pitot tubes not
meeting the appropriate geometic criteria are discarded and replaced. Manometers are verified to be level
and zeroed prior to each test run and do not require further calibration.
o Temperature Measuring Deyices. All thermocouple sensors mounted in Dry Gas Meter Consoles are
calibrated semi-annually with a MST-haceable thermocouple calibrator (temperahre simulator) and
verified during field use using a second MST-traceable meter. NlST-traceable thermocouple calibrators
are calibrated annually by an outside laboratory.
o 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.
o Dieital Calipers. Calipers are calibrated annually by Alliance by using gage blocls that are calibrated
annually by an outside laboratory.

Ouality Assurance Program
Barometer. The barometric pressrue is obtained from a nationally recognized agency or a calibrated
barometer. Calibrated barometers are checked prior to each field tip against a mercury barometer. The
barometer is acceptable if the values agree within * 2 percent absolute. Barometsrs not meeting tlis
requirement are adjusted or taken out ofservice.
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 intemally. If conducted internally, they are weighed on a
MST traceable balance. If the weight does not meet the expected criteria, they are replaced.
Other Equipment. A mass flow contoller 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 prograJn include:
o Cleaned glassware and sample hain components will be sealed until assembly.
o Sample trains will be leak checked before and after each test run.
o Appropriate probe, filter and impinger temperatures will be maintained.
r The sa:npling port will be sealed to prevent air from leaking from the port.
o Dry gas meter, AP, AH, temperature and pump vacuum data will be recorded during each sample point.
o An isokinetic sampling rate of 90-l l0% will be maintained, as applicable.
o All raw data will be maintained in organized manner.
. All raw data will be reviewed on a daily basis for completeness and acceptability.
