Emission rates were calculated using a standard fuel factor of 9,780 dscf/mmBtu 

for Bituminous Coal. Run 2 failed a post test leak check and consequently an 

additional run was added to the test program. Additionally, another mercury test 

was performed on April 29, 2010 after results for the first test run that day 

indicated no mercury was detected in one sample. The field data sheets for Run 

2 and the additional mercury test are found in the Appendix. 

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 rate for these compounds.

3.0 Test Methodology 

Emissions testing were conducted following the methods specified in 40 CFR, 

Part 60, Appendix A and 40CFR63, Appendix A. Schematics of the sampling 

trains used and copies of field data sheets 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 characteristics of the measurement location are 

summarized below, in Table 4.

Method 2 Volumetric Flow Rate Determination 

Gas velocity was measured following Method 2, 40 CFR, Part 60, Appendix A, 

for purposes of calculating stack gas volumetric flow rate. An S-type pitot tube, 

differential pressure gauge, thermocouple and temperature readout were used to 

determine gas velocity at each sample point. All of the equipment used was 

calibrated in accordance with the specifications of the Method. Calibration data is 

presented in the Appendix.

Method 3A Oxygen (O2)/Carbon Dioxide (CO2) Determination 

A Servomex analyzer was used to determine stack gas oxygen (O2) and carbon 

dioxide content and, by difference, nitrogen content in accordance with Method 

3A, 40 CFR, Part 60, Appendix A for purposes of calculating stack gas molecular 

weight as well as for calculating emissions on a lb/mmBtu basis. The O2

instrument has a nondispersive infrared-based detector and operates in a range 

of 0-25%, the CO2 instrument also uses a nondispersive infrared-based detector 

and operates in the range of 0-20%. All of the equipment used was calibrated in 

accordance with the specifications of the Method. 

OTM27 Filterable Particulate Determination

Stack gas filterable particulate concentrations and emission rates were 

determined in accordance with Other Test Method 27 (OTM27) for determination 

of particulate matter less than 2.5 microns. An Environmental Supply Company, 

Inc. sampling train was used to sample stack gas at a constant rate, as specified 

in the Method. Filterable particulate matter was separated into two fractions; one 

containing less than PM2.5, the other greater than PM2.5. 

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 (CPM) was collected in impingers after 

filterable particulate material was collected 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 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 

changes is found in the Appendix. 

CPM was 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 were purged with nitrogen (N2) immediately after sample 

collection to remove dissolved sulfur dioxide (SO2) gases from the impingers. 

The impinger solution was then extracted with acetone and methylene chloride 

(MeCl2). The organic and aqueous fractions were dried and the residues 

weighed. The total of the aqueous and organic fractions represents the CPM. 

The samples were analyzed by PES personnel in Des Plaines, Illinois.

Method 29 Trace Metals Determination

Stack gas metals concentrations and emission rates were determined in 

accordance with Method 29. An Environmental Supply Company, Inc. sampling 

train was used to sample stack gas, in the manner specified 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 (ICP): Antimony, Arsenic, Beryllium, 

Cadmium, Chromium, Cobalt, Lead, Manganese, Nickel, and Selenium. All of the 

equipment used was calibrated in accordance 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 using three (3) test points at the Boiler 4 Outlet Duct. 

Per Method 30B sampling, each sample was collected on the paired in-situ 

sorbent traps. A tube of silica 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. analyzer for total gaseous mercury.
