### Emission rates were calculated using a st andard fuel factor of 9,820. Compounds expressed above as less than or equal to values had a fraction or fractions that were below detection limits. Detection limits for each fraction were used to determine the emission ra te for these compounds.ICR Boiler MACT Emissions R eport PES Report No.: M101402 We Energies –Oak Creek Power Plant Unit 8 Outlet Duct April 6, 8, and 9, 2010

# 3.0 Test Methodology

Emissions testing were conducted followi ng the methods specified in 40 CFR, Part 60, Appendix A and 40CFR63, Appendi x A. Schematics of the sampling trains used and copies of field data sheet s for each test run are included in the Appendix.
The following methodologies were used during the test program:



## Method 1 Sample and Velocity Traverse Determination Test measurement points were selected in accordance with Method 1, 40 CFR, Part 60, Appendix A. The characteristi cs of the measurement location are summarized below, in Table 4.

## Method 2 Volumetric Flow Rate Determination Gas velocity was measured following Meth od 2, 40 CFR, Part 60, Appendix A, for purposes of calculating stack gas volume tric flow rate. An S-type pitot tube, differential pressure gauge, thermocoupl e and temperature readout were used to determine gas velocity at each sample point. All of t he equipment used was calibrated in accordance with the specificat ions of the Method. Calibration data is presented in the Appendix.ICR Boiler MACT Emissions R eport PES Report No.: M101402 We Energies –Oak Creek Power Plant Unit 8 Outlet Duct April 6, 8, and 9, 2010



### 4 

## Method 3A Oxygen (O2)/Carbon Dioxide (CO2) Determination A Servomex analyzer was used to determine stack gas oxygen (O 2 

### ) and carbon dioxide content and, by difference, ni trogen content in accordance with Method 3A, 40 CFR, Part 60, Appendix A for purpos es of calculating stack gas molecular weight as well as for calculat ing emissions on a lb/mmBtu. The O 2 

### instrument has a nondispersive infrared-based detector and operates in a range of 0-25%, the CO 2 

### instrument also uses a nondispersi ve infrared-based detector and operates in the range of 0-20%. All of the equipm ent used was calibrated in accordance with the specifications of the Method.



## OTM27 Filterable Particulate Determination Stack gas filterable particulate c oncentrations and emission rates were determined in accordance with Other Te st Method 27 (OTM27) for determination of particulate matter less than 2.5 micr ons. An Environmental Supply Company, Inc. sampling train was used to sample sta ck gas at a constant rate, as specified in the Method. Filterable particulate ma tter was separated into two fractions; one containing less than PM 2.5, 

### the other greater than PM 2.5


### .



## OTM 028 Condensable Particulate Determination Stack gas condensable particulate concentrations and emission rates were determined in accordance with the dry draft impinger method, in conjunction with Method OTM27 filterable particulate sampling. Condensable particulate matter was collected in the impinger portion of the Method OTM027 sampling train.
The condensable particulate matter (CP M) was collected in impingers after filterable particulate material was co llected utilizing Method OTM27. The organic and aqueous fractions were 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 afte r the final heated filt er. One modified Greenburg Smith impinger and an ambient temperature f ilter follow the water dropout impinger. A schematic of the sampling train configured with these changes is found in the Appendix.
CPM was collected in the water dropou t, modified Greenburg Smith impinger and ambient filter portion of the sampling tr ain as described in this Method. The impinger contents were purged with nitrogen (N 2 

### ) immediately after sample collection to remove dissolved sulfur dioxide (SO 2 

### ) gases from the impingers. The impinger solution was then extrac ted with acetone and methylene chloride (MeCl 2 

### ). The organic and aqueous fractions were dried and the residues weighed. The total of the aqueous and or ganic fractions represents the CPM. The samples were analyzed by PES personnel in Des Plaines, Illinois.ICR Boiler MACT Emissions R eport PES Report No.: M101402 We Energies –Oak Creek Power Plant Unit 8 Outlet Duct April 6, 8, and 9, 2010



### 5 

## Method 29 Trace Metals Determination Stack gas metals concentrations and emission rates were determined in accordance with Method 29. An Environm ental Supply Company, Inc. sampling train was used to sample stack gas, in the manner specifi ed in the Method. Analyses of the samples collected were conducted by Maxxam Analytics, Inc. Samples were analyzed for the following metals, using Inductively Coupled Argon Plasma emission spectroscopy (I CP): Antimony, Arsenic, Beryllium, Cadmium, Chromium, Cobalt, Lead, Manganese, Nickel, and Selenium. All of the equipment used was calibrated in accor dance with the specifications of the Method. Calibration data is presented in the Appendix.



## Mercury Determination by Method 30B (Sorbent Trap Method) Paired trains were utilized sampling three (3 ) test points at the Unit 8 Outlet Duct.
Per Method 30B sampling, each sample was collected on the paired in-situ sorbent traps. A tube of silic a was used to capture remaining moisture prior to the sample reaching the gas metering system.
The sample train used for this test program was designed by APEX, Inc. and meet all requirements for Method 30B sampling. Samples were analyzed onsite utilizing an Ohio Lumex, Inc. analyze r for total gaseous mercury.ICR Boiler MACT Emissions R eport PES Report No.: M101402 We Energies –Oak Creek Power Plant Unit 8 Outlet Duct April 6, 8, and 9, 2010
