measured oxygen concentration, the published fuel factor, a calibrated gas meter and the fuel heating value.
The pollutant concentrations will be converted to mass emission factors (lbiMMBtu) using procedures outlined in
U.S. EPA Reference Test Method 19. The published dry 01 based fuel factor (F-Factor) of 8,7 l0 dscf/MMBtu for
natural gas will be used in the calculations.
3.6 Quality Assurance/Quality Control - tl.S. EPA Reference Test Methods 3A, 7E and l0
Cylinder calibration gases will meet EPA Protocol I (+l- 2oh) 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 rvill 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 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 rvill be observed until it reaches a stable value, and this value
rvill 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. lf the Low-
Level gas is zero gas, the acceptable response must be 5.0 percent of the upscale gas concentration or 0.5 ppml9/o
(whichever was less restrictive). 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 Systern Bias for each gas must be within 5.0 percent of the Calibration Span or 0.5 ppmv/%o 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

Sire Specific Test Plan
Testing Methodology
percent of the Calibration Span or 0.5 ppmv/7o 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 Systern Bias must be within 3 percent of the Calibration Span or 0.5 ppmvi%
absolute difference or the Calibration Error Test and System Bias must be repeated.
To determine the nurnber of sampling points, a gas stratification check will be conducted prior to initiating testing.
The pollutant concentrations will be measured at fwelve traverse 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 systern response time.
lf the polf utant concentration at each traverse point does not differ more than 5oh or 0.5 ppml}.3oh (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 l07o 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 l0% or 1.0 ppm/0.5%o from the average
concenffation, then sampling will be conducted at a minimum of fwelve (12) traverse points. Copies of stratification
check data will be included in the Quality Assurance/Quality Control Appendix of the report.
An NO:- NO converter check will be performed on the analyzer prior to initiating testing. Mid-level nitrogen oxide
protocol I calibration gas will be mixed at a l:l ratio with span [evel protocol I oxygen calibration gas in a Tedlar
sample bag to form NO2 gas. The NOz gas will be delivered to the nitrogen oxides analyze( directly from a Tedlar
sample bag. The response of the analyzer must be stable for the 30-minute duration of the test with the variation
less than 2.0o/o at the end of the test from the nraximum value of the test.
A Data Acquisition System with banery backup will be used to record the instrument response in one (l) minute
averages. Thedatawill becontinuouslystoredasa*.CSVfileinExcel fonnatontheharddriveofacomputer. At
the completion of testing, the data will also be saved to the Alliance seryer. 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, pennanent 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
recal ibrated 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.
r 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 ofservice.
o Other Equinment. 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, Subpan 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:
r The sampling port will be sealed to prevent air from leaking from the port.
o All raw data will be maintained in an organized manner.
o All raw data will be reviewed on a daily basis for completeness and acceptability.
