# 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.

Table 1-1: HAPs Categories and Potential Surrogates Category HAPs Group Potential Surrogate A Non-dioxin / Furan Organic Carbon Monoxide, Volatile Organic Compounds or Total Hydrocarbons B Dioxin / Furan Organic Ratio of Fuel-bound Sulfur to Fuel-bound Chlorine

# 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).

# TEST PROGRAM SYNOPSIS (CONTINUED) Oxygen (O 2 

# ) and carbon dioxide (CO 2 

# ) data (units of dry volume percent, % dv 

# ) used in molecular weight calculations, O 2 

# correction and calculation of F d 

# -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 O 2 

# and CO 2 

# 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 O 2 

# and CO 2 

# 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, O 2 

# and CO 2 

# data were obtained from a continuous paramagnetic / non-dispersive infrared (NDIR) analyzer operated concurrently and in parallel with the other analyzers.

H 2 

# O 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, H 2 

# O 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 (N 2 

# ), 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.

# 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 (CH 4 

# ) Total hydrocarbons (THC) and methane (CH 4 

# ) emissions were determined, using a flame ionization analyzer (FIA) equipped with a chromatographic column for separate CH 4 

# 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 (C 3 

# H 8 

# ) 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. H 2 

# O data, used for moisture correction of concentration data, was obtained from an overlapping Category A (Non-dioxin / Fura n Organic HAPS) test run, with an incorporated Method 4 measurement. Analyzer calibrations were performed by introducing zero air, high, mid- and low range C 3 

# H 8 

# and CH 4 

# 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 CH 4 

# (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.
VOCVOC 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. H 2 

# O 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 wereprovided from ALS Laboratory Group inBurlington, 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 surrogate s 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 Ameri ca 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.

# TEST PROGRAM SYNOPSIS (CONTINUED) SVOCSVOC 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 H 2 

# O 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 (dsc m), 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.

# O 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. Miksch, et al., Analytical Chemistry, November 1981, 53, pp. 2118-2123.

# 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 CO 2 

# 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. H 2 

# O data, used for moisture correction of concentration data, were obtained from an overlapping Method 5/29 test run.

# 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 H 2 

# O 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.

FPM 2.5 

# / Condensable Particulate Matter (CPM) FPM 2.5 

# 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 H 2 

# O 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 FPM 2.5 

# 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 FPM 2.5 

# 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 FPM 2.5 

# / 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 (SO 2 

# ) and nitrogen oxides (NO X 

# ) 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 NO X

# 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.
