INTRODUCTION 

Ameren Services Company (Ameren Services) contracted Clean Air Engineering 

(CleanAir) to perform emissions testing at the Ameren UE Sioux Power Plant (Sioux), 

located in West Alton, Missouri, to provide data for the Utility Boiler MACT ICR. 

All testing was conducted using reference test methods promulgated by the US 

Environmental Protection Agency (EPA), the ASTM International (ASTM), and in 

coordination with OSHA and Sioux safety requirements. 

Key Project Participants 

Individuals responsible for coordinating and conducting the test program were: 

 Don Schuh – Ameren Services Company 

 Mike Tomasovic – Ameren Services Company 

 Steve Norfleet – RMB Consulting and Research 

 Ben Wiltse – CleanAir 

Background 

On November 10, 2009, the EPA, under authority of Section 114 of the Clean Air Act 

(CAA), issued an Information Collection Request (ICR) for coal- and oil-fired 

electrical generating units (EGUs), in support of its efforts to develop National 

Emission Standards for Hazardous Air Pollutants (NESHAP). Included in the ICR 

were requirements for sampling and analysis of stack gases, fuels and scrubber water 

from a large number of EGUs throughout the United States. 

This information will be used to determine if a correlation exists between certain 

categories of hazardous air pollutants (HAPs) and potential surrogates. If so, future 

HAPs regulations may be based upon emission levels of surrogate pollutant standards. 

Table 1-1 lists the four (4) HAPs categories and their potential surrogates.

Discussion of Test Program 

General Considerations 

The primary goal of the test program was to obtain a complete set of gaseous emissions 

data and fuel analysis data for HAPs Categories A, C and D from Unit 2. Per EPA 

Method 1 requirements, a verification of the absence of cyclonic flow was performed at 

the Unit 2 Stack prior to sampling. 

Test runs for constituents in the same category were performed at concurrent or 

overlapping times. All gaseous emissions tests were comprised of three (3) test runs 

that met or exceeded the minimum sampling times and volumes specified by Tables 

1.2a, 1.2b, 1.2c and 1.2d in the Utility Boiler MACT ICR (excluding specifications 

known to be erroneous).

Revision D0a, Draft 

TEST PROGRAM SYNOPSIS (CONTINUED) 

Oxygen (O2) and carbon dioxide (CO2) data (units of dry volume percent, %dv) used in 

molecular weight calculations, O2 correction and calculation of Fd-based emissions 

(units of lb/MMBtu) were obtained in the following manner during the test program: 

• For non-instrumental (wet) sampling methods, a modified version of EPA 

Method 3B was utilized. 

o Multi-point, integrated gas samples (IGS) were continuously collected at a 

constant rate from a slipstream of the exhaust of the sample trains into a 

flexible vinyl bag (IGS bag), per Method 3B specifications. 

o A calibrated paramagnetic/IR analyzer was used in place of a traditional 

Orsat analyzer to measure drift-corrected O2 and CO2 concentrations of the 

IGS bags, per Method 3A specifications. 

o Multiple IGS bags were collected during lengthy sample runs to ensure 

sample train integrity. Average O2 and CO2 results for each test run were 

calculated. 

o Documentation of preliminary instrument calibrations and post analysis 

calibration checks were included in the appendices of the final report. 

• For instrumental (continuous) test methods and SW-846 0031, O2 and CO2 data 

were obtained from a continuous paramagnetic / non-dispersive infrared 

(NDIR) analyzer operated concurrently and in parallel with the other analyzers. 

H2O data (units of volume percent, %v), used for moisture correction of concentration 

data, were obtained in the following manner during the test program: 

• For non-instrumental (wet) sampling methods, EPA Method 4 measurements 

were incorporated into the sampling and recovery procedures. 

• For instrumental (continuous) sampling methods using traditional CEM 

analyzers, H2O data were obtained from another overlapping test run with an 

incorporated moisture measurement. 

Gaseous Emissions Testing - Category A 

Carbon Monoxide (CO)

Carbon monoxide (CO) emissions were determined by infrared (IR) absorbance, per 

Method 10 procedures. A sample gas stream was extracted at a constant rate, 

conditioned to remove moisture, and delivered to an IR analyzer which measured 

concentration on a dry basis. 

Calibration error checks were performed by introducing zero nitrogen (N2), high-range 

CO and mid-range CO calibration gases to the inlet of the analyzer during calibration 

error checks. Bias checks were performed before and after each sampling run by 

introducing calibration gas to the inlet of the sampling system’s heated filter. 

Documentation of interference checks is included in Appendix D.

SIOUX POWER PLANT CleanAir Project No: 10959-2 

PROJECT OVERVIEW 1-7 

Revision D0a, Draft 

TEST PROGRAM SYNOPSIS (CONTINUED) 

Minute-average data points for CO concentration (dry basis) were collected over a 

period of two (2) hours. The sampling system traversed all of the Method 1 points 

during each run; therefore, no stratification check was necessary. Per Method 10 

requirements, the average results were drift-corrected. 

Note that the minimum sample volume of 1.7 cubic meters, specified in Table 1.2a of 

the Utility Boiler MACT ICR, was known to be erroneous as sample volume 

requirement. Continuous instrumental analyzer test methods generally do not have 

sample volume requirements. 

Total Hydrocarbons (THC) and Methane (CH4)

Total hydrocarbons (THC) and methane (CH4) emissions were determined, using a 

flame ionization analyzer (FIA) equipped with a chromatographic column for separate 

CH4 measurement. EPA approval for the use of THC analyzers equipped with a 

separate chromatographic column was given in the response to TEST-029, under the 

FAQ section of the utility MACT ICR website: 

(http://utilitymacticr.rti.org/FAQ/FAQEmissionsTesting.aspx). 

Sample gas stream was extracted at a constant rate and delivered at 248 ± 25°F to an 

FIA, which measured concentration in terms of propane (C3H8) on an actual (wet) 

basis. A portion of the sample was separated within the THC analyzer and sent to the 

gas chromatograph (GC), which measured the methane concentration in the sample. 

H2O data, used for moisture correction of concentration data, was obtained from an 

overlapping Category A (Non-dioxin / Furan Organic HAPS) test run, with an 

incorporated Method 4 measurement. 

Analyzer calibrations were performed by introducing zero air, high, mid- and low range 

C3H8 and CH4 calibration gases to the inlet of the sampling system’s heated filter. Drift 

checks were performed before and after each sampling run in a similar manner. 

Minute-average data points for THC concentration (as propane, wet basis) and CH4

(wet basis) were collected over a period of two (2) hours for each run. The sampling 

system traversed all of the Method 1 points during each run. 

VOC

VOC emissions were determined using SW846-0031 and a constant rate (nonisokinetic), single-point sample train. The sampling train consisted of a condenser, a 

set of three (3) traps (two Tenax®-GC and one Anasorb®-747) and a dry gas meter. 

H2O data, used for moisture correction of concentration data, were obtained from 

overlapping SW-846 0010 test runs.

TEST PROGRAM SYNOPSIS (CONTINUED) 

Sampling was conducted from a single point in the stack. Approximately 20 L of 

sample gas was drawn through a set of sample traps at a rate of approximately 1 liter 

per minute (lpm). Afterwards, the traps were capped and replaced with a fresh set. 

Four (4) sets of traps were used per test run. Each run was executed over the two-hour 

period of the other Category A tests, but only 80 minutes of actual sampling occurred. 

This was verified with EPA as the intent of the seemingly conflicting specifications for 

sample volume and time in Table 1.2a of the Utility Boiler MACT ICR. 

One (1) set of tubes per test run was attached to the sample train during the leak-check 

and recovered as a field blank. One (1) set of unused/unopened tubes was collected to 

serve as a trip blank. An HPLC water reagent blank was also collected during sample 

recovery. All SW846-0031 sample traps were stored under refrigeration or on ice or 

cold packs prior to analysis, including shipment to the laboratory for analysis. 

The sample trap sets and condensate liquid were shipped to Test America in Knoxville, 

Tennessee, for analysis. The tubes were provided from ALS Laboratory Group in 

Burlington, Ontario, but they became unable to conduct the analyses within the holdtime required by the method. The laboratory followed specifications in SW846 8260 

when conducting the requisite surrogate spiking, samples and blank analysis, and 

reporting of the results. Reporting of tentatively identified compounds (TICs) was not 

conducted since it was not required for the ICR. 

The tubes collected from Runs 1D, 2D and 3D were not reported. Test America had 

previously observed poor recovery of surrogates and spikes from “Anasorb only” tubes. 

Test America usually uses Anasorb tubes containing a small amount of Tenax at the 

front of the tube. Since the tubes used during the tests were supplied by ALS 

Laboratory Group, the Anasorb tubes did not contain any Tenax. 

The lab suspected that there would be problems spiking and analyzing the Anasorb 

tubes, so a series of test samples were analyzed to demonstrate the recovery of target 

analytes and surrogates from the Anasorb tubes used. This study was conducted using 

the tube set from Run 1D. The results of this study are included in the miscellaneous 

section of the Test America Lab Report. 

An abbreviated version of the Test America laboratory report is included in Appendix 

G, while the full version of the lab report is contained in the electronic Adobe pdf 

version of this report.

SVOC

SVOC emissions were determined following SW846-0010, using an isokinetic, multipoint sample train. The sampling system consisted of a nozzle, heated probe, heated 

pre-cleaned filter, condenser, XAD trap (packed with an SVOC-adsorbing resin), 

impinger train (for additional SVOC collection and H2O removal/measurement) and a 

dry gas meter. 

The sampling system traversed all of the Method 1 points during each sample run. A 

minimum of 1.7 dry standard cubic meters (dscm), or 60 dry standard cubic feet (dscf), 

were sampled during each two-hour run. After each sampling run, the probe rinse, 

filter, XAD trap and the impinger train catch and rinse were recovered following 

method procedures. 

One (1) complete field train blank (transported to the location, heated, leak-checked 

and recovered as if it were an actual test sample) and reagent blanks were collected as 

part of sample recovery. All samples were stored under refrigeration or on ice or cold 

packs prior to analysis, including shipment to the laboratory for analysis. The sample 

traps, rinses and blanks were shipped to ALS Laboratory Group in Burlington, Ontario, 

for analysis. The laboratory followed specifications in SW846 8270D when conducting 

the requisite surrogate spiking, sample and blank analyses, and reporting of the results. 

CH2O

CH2O emissions were determined following EPA Method 316, as approved in the EPA 

response to Question EPA-003, under the FAQ section of the utility MACT ICR 

website (http://utilitymacticr.rti.org/FAQ/FAQAllCategories.aspx#EPA-003). Flue gas 

was sampled isokinetically from the source and CH2O present was collected in a series 

of impingers containing high purity water (ASTM Type 1 or equivalent). 

The sampling system traversed all of the Method 1 points during each run. A minimum 

of 1.7 dry standard cubic meters (dscm), or 60 dry standard cubic feet (dscf), was 

sampled during each two-hour sample run. 

Sample analysis was performed by Enthalpy Analytical, Inc., located in Durham, North 

Carolina. The samples were analyzed following Method 316 procedures, incorporating 

procedures mentioned in Section 4.0 of the method and described in reference R.R.

TEST PROGRAM SYNOPSIS (CONTINUED) 

Gaseous Emissions Testing - Category C 

Hydrogen Chloride (HCl), Hydrogen Fluoride (HF) and Hydrogen Cyanide (HCN) 

Hydrogen chloride (HCl), hydrogen fluoride (HF) and hydrogen cyanide (HCN) 

emissions were determined, using a modified Method 26A sample train. The sampling 

train was modified by using a series of four (4) impingers containing 6N sodium 

hydroxide (NaOH) solution to allow the pH to be kept above 12 in order to collect any 

HCN present in the flue gas. 

Sampling was conducted isokinetically traversing all of the Method 1 sampling points 

during each run. A minimum of 0.85 dry standard cubic meters (dscm), or 30 dry 

standard cubic feet (dscf), was sampled during each 60-minute sampling run. The pH 

of the impinger solution was monitored during sampling by adding Alizarin-yellow R 

indicator to the impinger solution and by installing a pH meter probe in the last NaOH 

impinger. The color and pH of the impinger solution were recorded on the field data 

sheets during each set of sample readings. 

The EPA approved sampling for one (1) hour, instead of three (3), if the CO2

concentration was greater than 3%, which was the case at Unit 2. The approval can be 

found in the EPA response to Question TEST-025, under the FAQ section of the utility 

MACT ICR website (http://utilitymacticr.rti.org/FAQ/FAQEmissionsTesting.aspx). 

The samples were sent to Enthalpy Analytical, Inc., located in Durham, North Carolina, 

for analysis. The samples were analyzed following Method 26A procedures, while also 

meeting Conditional Test Method (CTM) 033 QA/QC requirements for HCN analysis. 

The HCl concentration in the reagent blank was comparatively high relative to the 

concentrations in the samples. The HCl results were not blank-corrected. HF and HCN 

concentrations in the reagent blank were below detection. 

Gaseous Emissions Testing - Category D 

Mercury (Hg)

Mercury (Hg) emissions were determined following EPA Method 30B, using a constant 

rate, multi-point sampling apparatus. Sample gas was drawn through paired in-stack 

sorbent traps, each with two (2) sections containing iodinated, activated charcoal (to 

demonstrate lack of breakthrough). The first section of one (1) of the traps was spiked 

with a known amount of Hg (to demonstrate recovery) during all runs. Each trap had a 

separate sample path with a unique moisture removal system and a dry gas meter. H2O 

data, used for moisture correction of concentration data, were obtained from an 

overlapping Method 5/29 test run.

Revision D0a, Draft 

TEST PROGRAM SYNOPSIS (CONTINUED) 

The Method 30B sampling system traversed all of the Method 1 points. The volume of 

gas sampled varied during each of the two-hour runs, depending on the prevailing flue 

gas Hg concentrations. (Method 30B specifies collection of 50% to 150% of the 

preliminary spike amount during each test run.) A preliminary run was conducted to 

determine the sampling rate used for Run 1; subsequent runs were adjusted 

accordingly. 

Sorbent traps were analyzed on-site using direct thermal desorption with Zeeman 

atomic absorption spectrometry. An Ohio Lumex model RA-915+ analyzer with 

RP-M324 detector was used for the analyses. The actual analytical procedures were 

similar to those contained in Method 30B. 

Run 1 did not meet all of the QA/QC criteria required by the method. A fourth sample 

run was conducted and reported. The data from Run 1 is included in the appendices of 

this report, but not included in average or in Table 2-13 on Page 2-69. 

Runs 2 through 4 met all QA/QC criteria required by the method. Copies of QA/QC 

results from all sampling results can be found in Appendix G. 

Filterable Particulate Matter (FPM) / Metals

Filterable particulate metals (FPM) and metals emissions (excluding Hg) were 

determined using a combined EPA Method 5/29 isokinetic, multi-point sample train. 

The sampling system consisted of a nozzle, heated probe, tared high-efficiency quartz 

filter, impinger train (for metals collection and H2O removal/measurement) and a dry 

gas meter. 

The sampling system traversed all of the EPA Method 1 points during each run. A 

minimum of 3.4 dry standard cubic meters (dscm), or 120 dry standard cubic feet 

(dscf), was sampled during each four-hour run. The nozzle, probe and filter were 

recovered, per Method 5 specifications; the entire sample train (nozzle, probe, filter, 

impinger train) were then recovered, per Method 29 requirements. 

Gravimetric analysis of the FPM fractions was performed by Clean Air Engineering, 

located in Palatine, Illinois. The metals analysis was conducted by Element One, Inc., 

located in Wilmington, North Carolina. Once the particulate weights were determined, 

the probe and nozzle rinses and filters were also sent to Element One, where they were 

re-dissolved in concentrated acid and combined. The combined samples, as well as the 

samples recovered from the impinger train, were each be reduced to near dryness, 

digested and analyzed for metals, using inductively-coupled plasma mass spectroscopy 

(ICPMS). Element One, Inc. performed the metals analysis per 

SW846-6020 requirements.

TEST PROGRAM SYNOPSIS (CONTINUED) 

The FPM results from combined Method 5/29 sampling are included in Table 2-9 on 

page 2-54. The metals results from the sampling are included in Table 2-11 on pages 

2-56 through 2-58. 

FPM2.5 / Condensable Particulate Matter (CPM)

FPM2.5 and condensable particulate matter (CPM) emissions were determined using a 

combined OTM-27/OTM-28 isokinetic, multi-point sample train. The sampling system 

consisted of an in-stack cyclone/filter assembly (which speciated and collected FPM 

greater than and less than 2.5 microns), Teflon-lined probe, impinger train with a 

Teflon membrane filter (for CPM collection and H2O removal/measurement) and dry 

gas meter. 

The sampling system traversed all of the EPA Method 1 points during each run. A 

minimum of 3.4 dry standard cubic meters (dscm), or 120 dry standard cubic feet 

(dscf), were sampled during each run. Table 1.2d in the Utility Boiler MACT ICR 

specifies a four-hour run; however, nominally six-hour sample runs were performed to 

ensure the minimum required amount of volume was sampled. 

The FPM2.5 portion of the cyclone and the filter were recovered, per OTM-27 

requirements. The impinger train was purged with nitrogen at a rate of 20 liters per 

minute (lpm) for one (1) hour following each test run and prior to recovery. 

One (1) complete field train blank and reagent blanks were collected as part of sample 

recovery. Samples and blanks were returned to CleanAir Analytical Services for 

gravimetric analysis. The FPM2.5 and CPM results were blank-corrected. 

The silica gel impinger from the Run 1 sample train broke during the post test nitrogen 

purge. The failure did not preclude the recovery and analysis of the sample collected in 

the other impingers. To reduce the potential of this type of failure, the silica gel 

impinger from the sampling run was replaced with a fresh, pre-weighed silica gel 

impinger prior to purging the sample trains for Runs 2 and 3. The net weight gain from 

both the silica gel impinger used for the run and the one used for the purge was added 

together for the total moisture calculations for both runs. 

Based on moisture data from Runs 2 and 3, an estimated gross weight was used for the 

silica gel impinger from Run 1 to yield a similar silica gel weight gain with respect to 

the other impingers. The test conditions were very similar for all three (3) runs so the 

moisture contents would be expected to be similar. 

The flue gas moisture content and isokinetic sampling rates during FPM2.5 / CPM 

sampling, as well as during concurrent FPM / metals sampling, are included in Tables 

2-10 through 2-12 on pages 2-64 and 2-68 of this report.

TEST PROGRAM SYNOPSIS (CONTINUED) 

Unit Operating Conditions 

All testing was performed at base load operating capacity. All air pollution control 

(APC) devices were in service and fully operational during this test program. To the 

nearest extent possible, operating set points should be the same as those used during 

annual compliance testing. 

Fuel Analysis 

Sioux representatives collected the required fuel samples and delivered them to 

CleanAir personnel prior to demobilization from the site. One (1) composite coal 

sample was prepared for each test run of an emissions testing category. Therefore, this 

test program required collection of: 

• Three (3) composite samples for Category A, 

• Three (3) composite samples for Categories C and D (since emissions testing 

occurred concurrently for these categories). 

Each composite fuel sample was labeled with a collection date, collection time and run 

number by Sioux representatives. 

Section 2.2 of the ICR, Part B, Enclosure 1, detailed the required multi-stage 

compositing procedure for each fuel sample. The guidance document containing 

additional information on fuel sampling, publicly available from the Electric Power 

Research Institute (EPRI), was also followed. 

The fuel samples were analyzed by CONSOL, located in South Park, Pennsylvania. 

The results of analyses can be found in Appendix J. 

Process Data 

Ameren Services supplied process data required for the ICR. The process was 

collected and reported as daily averages over a 30-day period, which included the 

emission testing and fuel analysis reporting. Sulfur dioxide (SO2) and nitrogen oxides 

(NOX) data from the Unit 2 continuous emissions monitoring system (CEMS) were 

collected and reported as daily averages over a 30-day period, which included the 

emission testing and fuel analysis reporting in lieu of conducting stack testing. The 

Unit 2 CEMS meets the requirements of the applicable Performance Specifications. 

Copies of process and CEMS data are included in Appendices H and I, respectively.

PROCESS DESCRIPTION 

Ameren UE owns and operates the Sioux Power Plant, located in West Alton, Missouri. 

Unit 2 is a Babcock and Wilcox cyclone-fired boiler installed in 1968 and rated at 

approximately 524 MWe gross and 4,920 million Btu per hour (MMBtu/hr) heat input. 

The boiler fires a mix of sub-bituminous and bituminous coals. 

The Unit 2 boiler utilizes an over-fire air system to control NOX emissions. Unit 2 is 

equipped with a cold side electrostatic precipitator (ESP) with flue gas conditioning to 

control particulate emissions. 

The testing described in this document was performed at the Unit 2 Stack. 

A schematic of the process indicating sampling locations is shown in Figure 3-1.

 Barrett Parker of USEPA requested that 4 points per point be sampled instead of the 3 points per point 

required by Method 1 since the furthest point in cannot be reached due to clearance issues.

 Clearance issues within the stack annulus limited overall sample train length to 72 inches. Because of 

this, the sample probe was only be able to reach 51-53 inches from the inside stack wall. The first point 

was located as far in as possible
