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

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. The O2 instrument has 

a nondispersive infrared-based detector and operates in a range of 0-25%, the 

CO2 instrument also uses a nodispersive 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 or equal to 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

OTM27 filterable particulate sampling. Condensable particulate matter was 

collected in the impinger portion of the OTM027 sampling train. 

The condensable particulate matter (CPM) was collected in impingers after 

filterable particulate material was collected utilizing 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 sampling three (3) test points at the Unit 8 Stack

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. 

Method CTM 033 Hydrogen Cyanide Determination

Stack gas hydrogen cyanide (HCN) concentrations were determined in 

accordance with Method CTM 033. An Environmental Supply Company sampling 

train was used to sample stack gas, in the manner specified in the Method. A 

multiple-point sample was extracted isokinetically from the gas stream and 

passed through 1.0 N sodium hydroxide (NaOH). In the sodium hydroxide, the 

HCN dissolved and formed cyanide (CN) ions. The sample train consisted of a 

Teflon® filter placed on the outlet of a heated borosilicate glass probe liner and 

four impingers. The first two impingers contained the sodium hydroxide, the third 

impinger was initially empty, and the fourth impinger contained silica gel to 

absorb any remaining moisture. A DI rinse was performed on each set of 

impingers, and samples were stored in nalgene sample containers for transport. 

The sodium hydroxide samples were then analyzed for HCN by Maxxam 

Analytics, Inc. All of the equipment used was calibrated in accordance with the 

specifications of the Method. Calibration data is presented in the Appendix.

Method 26A Hydrogen Chloride (HCl) and Hydrogen Fluoride 

(HF) Determination

Stack gas Hydrogen Chloride (HCI) and Hydrogen Fluoride (HF) concentrations 

and emission rates were determined in accordance with Method 26A. An 

Environmental Supply Company, Inc. sampling train was used to collect the 

sample. A multiple-point sample was extracted isokinetically from the gas stream 

and passed through dilute (0.1 N) sulfuric acid. In the dilute acid, the HCl 

dissolved and formed chloride (Cl) ions. The sample train consisted of a Teflon® 

filter placed on the outlet of a heated borosilicate glass probe liner and six 

impingers. The first three impingers contained the dilute sulfuric acid, the fourth 

and fifth impingers contained a 0.1 N sodium hydroxide (NaOH) scrubber 

solution, and the sixth impinger contained silica gel to absorb any remaining 

moisture. A DI rinse was performed on each set of impingers, and samples were 

stored in nalgene sample containers for transport. The dilute sulfuric acid 

samples were then analyzed for the above halides by Maxxam Analytics, Inc. All 

of the equipment used was calibrated in accordance with the specifications of the 

Method. Calibration data is presented in the Appendix.

Method 23 Dioxin and Furan/PCB and PAH Determination

Stack gas dioxin and furan, and PCB concentrations and emission rates were 

determined in accordance with Method 23, 40 CFR, Part 60, Appendix A with a 

spiked trap. An Environmental Supply Company sampling train was used to 

sample for concentrations of each of the constituents in the manner specified in 

the Method. 

After recovery, samples were analyzed by Maxxam Analytics, Inc. following the 

procedures specified in the Method. The specific techniques employed in 

analysis and laboratory data are detailed in the Appendix.
