# 2.0 Executive Summary

Selected results of the test program are summarize d below, in Table 3. A complete summary of emission test results follows the narrative portion of this report. 

## Table 3

**Test Results**

Test Location Test Parameter Emission Rate

Unit 31/32 Common Stack HCl, lb/mmBtu < 0.012 590

HF, lb/mmBtu < 0.056 089

HCN, lb/mmBtu < 0.00021 0



### 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.ICR Boiler MACT Emissions Report PES Report No.: M101404A City, Water, Light and Power

# 3.0 Test Method olog y

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 follo wing 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

s ummarized below, in Table 4.



## Table 4
**Sample Point Selection**

Test Location Upstream Di stance Downstream D istance Test Parameter Number of Sampling Points

Unit 31/32 Common Stack > 2.0 > 8.0 HCl, HF, HC N 12



## 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 a t 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.ICR Boiler MACT Emissions Report PES Report No.: M101404A City, Water, Light and Power

## Method 3A Oxygen (O **2**



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



## ) Determination Stack gas molecular weight was dete rmined in accordance with Method 3A, 40 CFR, Part 60, Appendix A. A Servomex analyzer was used to determine stack gas oxygen and carbon dioxide content and, by difference, nitrogen content. All of the equipment used was calibrated in accordance with the s pecifications of the Method.



## Method 26A Halide Determination Stack gas Hydrogen Chloride (HCI), Hydrogen Fluoride (HF), and Hydrogen Cyanide (HCN) concentrations and emission rates were determined in accordance with modified 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 1.0 N sodium hydroxide. The sample train consisted of a Teflon® filter placed on the outlet of a heated borosilicate glass probe liner and five impingers. The first three impingers contained the 1.0 N sodium hydroxide (NaOH) scrubber solution to collect the HCl , HF and HCN, the fourth impinger was empty and the fifth impinger contained silica gel t o 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 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.ICR Boiler MACT Emissions Report PES Report No.: M101404A City, Water, Light and Power
