3.0 SPECIFIC TEST PROCEDURES
Detailed test procedures are appended. Complete test runs will be performed for each constituent in accordance with the following United States Environmental Protection Agency (USEPA) methods.
1. The reference method traverse points will be selected in accordance with Method 1 to ensure acquisition of representative samples of pollutant and diluent concentrations over the flue gas cross section and to meet the requirements of Performance Specification (P.S.) 2 in Appendix
B of 40CFR60 for NOx; P.S. 3 and Method 3A for O2; and P.S. 4 or 4A and Method 10 for CO. 2. O2, NOx, and CO tests will be performed using USEPA Methods 3A, 7E, and 10, (40CFR60,
Appendix A) respectively, and 40CFR75 (Appendix A) at each location. A minimum of nine (9) tests will be completed consisting of twenty-one (21) minutes of continuous gaseous monitoring per test run. Sampling will be performed, depending on the results of the stratification test (if applicable), at three points (0.4, 1.2, and 2.0 meters or 17%, 50% and 83% of stack diameter) from the inside wall of the ductwork as per PS-2, 4, and/or 4A. The average gas effluent concentrations for each run will be determined from the average gas concentrations displayed by the gas analyzers and adjusted for the zero and upscale sampling system bias checks immediately preceding and following each run. 3. The reference method tests will be conducted so that they will yield results representative of the pollution concentration and emission rate from each unit and can be correlated with the
measurements from the continuous NOx, CO, and O2 monitoring systems. The O2 measurements will be conducted simultaneously with the pollutant concentrations. To properly correlate individual CEM pollutant values with the reference method data (NOx, CO,
and O2) the beginning and end of each reference method test run will be marked to include the exact time of day on the data acquisition system.

Protocol No. P250204

4. Each relative accuracy test audit will be completed within a 7-day period while the unit is combusting its primary fuel, pipeline natural gas.
5. USEPA Method 201A will be used to determine the concentration of filterable PM10 emissions at the test location. USEPA Method 202 will be used to determine the concentration of CPM
emissions at the test location. The sum of filterable PM10 and CPM will be PM10. The sample will be withdrawn at a constant rate. Dwell times will be utilized to maintain an isokinetic sampling rate throughout the test. Method 201A and Method 202 will be run using the same sampling train. Filterable PM will be collected in the cyclone, PM head, and on a glass fiber filter and CPM will be collected in dry impingers. Three (3) approximately one-hundred twenty (~120) minute 201A/202 test runs will be performed sampling a minimum volume thirty (30) dry standard cubic feet (DSCF) per run. Results will be reported in units of pounds per million British thermal units (lb/MMBtu), and pounds per hour (lb/hr). 6. A default fuel factor for pipeline natural gas of 8710 dscf/MMBtu (O2-based) and Method 19 will be used to calculate NOx and PM10 lb/MMBtu.

Acceptable flow conditions will be confirmed prior to PM testing per Method 1, section 11.4. 8.2 Method 2 Volumetric Flow Rate Determination
In order to determine the emission rate on a lb/hr basis, the stack gas velocity and volumetric flowrate are determined using Method 2.
Velocity pressures are determined by traversing the test location with an S-type Pitot tube and a
0–10-inch differential pressure gauge. Temperatures are measured using a K-type thermocouple with a calibrated digital temperature indicator. The molecular weight and moisture content of the gases are determined to permit the calculation of the volumetric flowrate. Sampling points utilized
are determined using USEPA Test Method 1, 40CFR60, Appendix A. 8.3 Method 3A Oxygen (O2) and Carbon Dioxide (CO2) Determination
A Servomex 1440 or equivalent analyzer is used to determine O2 and CO2 concentrations in the
stack gas during PM10 testing. Readings will either be taken manually, or continuously recorded with a data logging system. Linearity calibrations will be performed at the beginning of each test day, and mid-range and zero calibration checks will be performed after each run. Final O2 and
CO2 concentrations will be corrected for calibration error of the instrument. The instrument has a nondispersive infrared-based detector and operates in a range of 0-25% for O2 and 0-20% for CO2. Calibration data is presented in the Appendix of the final report.

PacifiCorp – Currant Creek Power Plant 7 © Mostardi Platt
8.4 Method 201A Filterable PM10 Determination Flue gas filterable particulate concentrations and emission rates will be determined in accordance with USEPA Method 201A. An Environmental Supply Company, Inc. sampling train will be used to sample flue gas at a constant rate, as specified in Method 201A. Filterable particulate matter
(FPM) will be separated into three fractions using particle-sizing device to separate particles
into greater than and less than PM10. 8.5 Method 202 Condensable PM10 Determination
Stack gas condensable particulate concentrations and emission rates will be determined in accordance with the Method 202, 40CFR51, Appendix M, in conjunction with Method 201A sampling. Condensable particulate matter (CPM) is collected in the impinger portion of the sampling train.
Glassware that will be used to collect and analyze Method 202 condensable particulate samples will be cleaned prior to the test with soap and water, and rinsed using tap water, deionized water, acetone, and finally, hexane. The CPM is collected in impingers after PM10material is collected utilizing Method 201A. The
organic and aqueous fractions are then taken to dryness and weighed. The total of all fractions represents the CPM. Compared to the December 17, 1991 promulgated Method 202, this Method includes the addition of a condenser, followed by a water dropout impinger immediately after the final heated filter. One modified Greenburg Smith impinger and an ambient temperature filter follow the water dropout impinger. A schematic of the sampling train configured with these updates is found in the Appendix. CPM is collected in the water dropout, modified Greenburg Smith impinger and ambient filter
portion of the sampling train as described in this Method. The impinger contents are purged with nitrogen (N2) immediately after sample collection to remove dissolved sulfur dioxide (SO2) gases from the impingers. The impinger solution is then extracted with DI water, acetone, and hexane.
The organic and aqueous fractions are dried and the residues weighed. The total of the aqueous, organic, and ambient filter fractions represents the CPM. 8.6 Method 7E Nitrogen Oxides (NOx) Determination
Method 7E, 40CFR60, Appendix A, is used for determining nitrogen oxides (NOx) emissions from each source. A gas sample is continuously extracted from the gas stream through a heated sample probe and gas conditioning system. A portion of the sample stream is conveyed via a
sampling line to gas analyzers for determination of NOx content. Prior to emissions sampling, the nitric oxide (NO)/NOx analyzer is zeroed and calibrated. High-range, mid-range, and zero gases are introduced into the NOx sampling system.
The sample gas manifold is then adjusted for emissions sampling. After each test run, the zeroes are checked and mid-range NOx gas is introduced into the sampling system to check calibration. The chemiluminescent reaction of NO and ozone (O3) provides the basis for this instrument operation. Specifically:

Protocol No. P250204
PacifiCorp – Currant Creek Power Plant 8 © Mostardi Platt
Light emission results when electronically excited nitrogen dioxide (NO2) molecules revert to their ground state. To measure NO concentrations, the gas sample to be analyzed is blended with O3
in a reaction chamber. The resulting chemiluminescence is monitored through an optical filter by a high-sensitivity photomultiplier positioned at one end of the chamber. The filter/photomultiplier combination responds to light in a narrow-wavelength band unique to the above reaction (hence,
no interference). The output from the photomultiplier is linearly proportional to the NO concentration. To measure NOx concentrations (i.e., NO plus NO2), the sample gas flow is diverted through a NO2-to-NO converter. The chemiluminescent response in the reaction chamber to the converted effluent is linearly proportional to the NOx concentration entering the converter. The instrument is operated in the NOx mode during all tests and calibrations. 8.7 Method 10 Carbon Monoxide (CO) Determination
Stack gas CO concentrations and emission rates are determined in accordance with Method 10.
A Thermo Fischer Scientific 48 Series Gas Filter Correlation Carbon Monoxide Analyzer is used to determine CO concentrations, in the manner specified in the Method. The instrument operates in a range of 0 ppm to the high-level span calibration gas to be determined on site. A list of calibration gases used and the results of all calibration and other required quality assurance checks will be appended to the final report. Copies of calibration gas certifications will also be appended to the final report. This testing will meet the performance specifications as outlined in the Method. Calibration gases are Protocol One gases. 8.8 Method 19 NOx Emission Rate Determination
USEPA Method 19 will be used to calculate the NOx emission rate from the test location in units of lb/MMBtu. The calculations will be based on the O2 or CO2 content of the sample gas and an appropriate F factor, which is the ratio of combustion gas volumes to heat input. An O2 based F factor of 8,710 dscf/MMBtu for combustion of natural gas will be used. 8.9 Gaseous Sampling Plan
Mostardi Platt will complete a minimum of nine (9) twenty-one (21) minute tests at each unit. The system will be calibrated as described above. Following each mid-test calibration, a stable on-line response will be regained prior the start of the next run. Data will be collected by a data logger. The actual time of each test will be compared to the output of the monitor taking into consideration response times determined on both the Mostardi Platt and plant CEM system. The determination of relative accuracy will be calculated based on the emissions as reported by each system corrected on the same basis.

9.0 QUALITY ASSURANCE PROCEDURES
Mostardi Platt recognizes the previously described reference methods to be very technique-oriented and attempts to minimize all factors which can increase error by implementing its Quality Assurance Program into every segment of its testing activities.
Dry and wet test meters are calibrated according to methods described in the Quality Assurance Handbook for Air Pollution Measurement Systems, Sections 3.3.2, 3.4.2 and 3.5.2. Percent error
for the wet test meter according to the methods is less than the allowable error of 1.0%. The dry test meters measure the test sample volumes to within 2% at the flowrate and conditions encountered during sampling. Calibration gases are Protocol One gases.
Raw data is kept on file at the Mostardi Platt offices in Elmhurst, Illinois. All samples from the test program will be retained for 60 days after the submittal of the report, after which they will be discarded unless Mostardi Platt is advised otherwise. Calculations are performed by computer. An explanation of the nomenclature and calculations along with the complete test results will be appended. Calibration data and copies of the raw field data sheets will also be appended. Mostardi Platt is a self-certified air emissions testing body (AETB) per 40CFR75, Appendix A, Section 6.1.2. The AETB information is summarized below:

Mostardi Platt Natural Gas Emission Rate Calculations
A pollutant emission rate (E), expressed as pounds of pollutant per million Btu heat input from the fuel combusted can be calculated by the following methods: A. C = Cs/7000 where, C = pollutant concentration, lb/dscf cs = pollutant concentration, grains/dscf B. If fuel flow is monitored and the fuel combusted during the test is sampled and analyzed for gross calorific value, then:
E = 6sd10GCV (lb/hr) rateflow fuel

%CO2 and %O2 are expressed as percent values: Fc = a factor representing a ratio of the volume of carbon dioxide generated to the calorific value of the fuel combusted, 1040 scf CO2/million Btu. F = a factor representing a ratio of the volume of dry flue gases generated to the calorific value of the fuel combusted, 8710 dscf/million Btu. D.
