The following methodologies were used during the test program:



# Method 1 Sample and Velocity Traverse Determination Test measurement points were selected in acc ordance 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 deter mine 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 (O **2**



# )/Carbon Dioxide (CO **2**



# ) Determination A Servomex analy zer was used to determine stack gas oxygen (O 2 

## ) 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 emis sions 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 nodispersive infrared

- based detector and operates in the range of 0

- 20%. All of the equipment used was calib rated 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 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 me thod, 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 mat eri al was colle cted 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, follo wed 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 i n 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 (N 2 

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

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

## ). The organic and aqueous fractions were dried and the residues weighed. The total of the aqueo us and organic fractions represents the CPM. The s amples 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 Environmenta l 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 pres ented 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 t rain 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 cyani de (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 Analyt ics, 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 imp ingers. 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 accordan ce 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 2 3, 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 a nalyzed by Maxxam Ana lytics, Inc. following the procedures specified in the Method. The specific techniques employed in analysis and laboratory data are detailed in the Appendix.
