2.0 Process Description

Belle River Power Plant employs the use of tw o (2) Babcock and Wilcox coal-fired boilers (Units 1 & 2) each designed to produce nom inally 4,550,000 pounds per hour of steam. Each Unit has a Siemens Power Corporation turbine generator with a rated capability of 635 (Unit 1) and 645 (Unit 2) gross megawatts (GMW). The typi cal coal blend for Unit 2 is a 70% low-sulfur western (LSW) / 30% midsulfur eastern (MSE). Full load conditions for the Unit will be nominally 600-645 MW, but may be lower during th e testing period due to unit-specific issues. Testing will occur on Unit 2 as close to full load conditions as possible, bu t not less than 90% of full load.

3.0 Sampling and Analytical Methodologies

Sampling and analytical methodologies for the emissions test program can be separated into nine categories as follows:

(1) Measurement of exhaust gas velocity, mo lecular weight, and moisture content; (2) Measurement of exhaust gas oxygen (O 2 

## ) and carbon dioxide (CO 2 

## ) concentrations using the procedures of U.S. EPA Method 3A; (3) Measurement of exhaust gas sulfur dioxide (SO 2 

## ) concentrations and emission rates using U.S. EPA Method 6C; (4) Measurement of exhaust gas carbon monoxide (CO) concentrations and emission rates using U.S. EPA Method 10; (5) Measurement of exhaust gas formaldehyde concentrations and emission rates using Method 0011; (6) Measurement of exhaust gas total hydrocarbons (THC) concentrations and emission rates using U.S. EPA Method 25A; DTE Belle River Power Plant BTEC Project No. 10-3991.00 Unit 2 Emissions Test Report 8/31/2010 1

## (7) Measurement of exhaust gas methane concentrations and emission rates using U.S. EPA Method 18; (8) Measurement of exhaust gas semi volatile organic HAPs concentrations and emission rates using Method 0010; and (9) Measurement of exhaust gas speciated vol atile organic HAPs concentrations and emission rates using Method 0031.

Descriptions of sampling and analytical met hodologies by category are su mmarized by Sections 3.1 through 3.9, respectively.

3.1 Exhaust Gas Velocity and Moisture Content

Measurement of exhaust gas velocity and mois ture content were conducted using the following reference test methods codified at Title 40, Part 60, Appendix A of the Code of Federal Regulations (40 CF R 60, Appendix A):

• Method 1 - “Sample and Velocity Trave rses for Stationary Sources” • Method 2 - “Determination of Stack Gas Velo city and Volumetric Flowrate” • Method 4 - “Determination of Moisture Content in Stack Gases”

Stack gas velocity traverses were conducted in accordance with the procedures outlined in Methods 1 and 2 (see Figure 1 for an exhaust stack tr averse point diagram). An S-type pitot tube with a thermocouple assembly, cal ibrated in accordance with Me thod 2, Section 4.1.1, was used to measure exhaust gas velocity pressures (using a manometer) a nd temperatures during testing. The S-type pitot tube dimensions were within sp ecified limits, therefore, a baseline pitot tube coefficient of 0.84 (dimensionless) was assigned.

A cyclonic flow check was performed at the samp ling location. The existence of cyclonic flow is determined by measuring the flow angle at each sample point. The flow angle is the angle between the direction of flow and the axis of the stack. If the average of the absolute values of the flow angles is greater than 20 degrees, cyclonic flow exists. The null angle was determined to be less than 20 degree s at each sampling point.

Exhaust gas moisture content was evaluated usin g Method 4. Exhaust gas was extracted as part of the Method 0010, 0011, and 0031 sampling trains (see Figures 4, 54, and 6 for schematics of the sampling trains). Exhaust gas moisture co ntent was then determined gravimetrically.

3.2 Oxygen and Carbon Dioxi de (USEPA Method 3A)

Exhaust gas O 2 

## and CO 2 

## concentrations were measured using the procedures of 40 CFR 60, Appendix A, Method 3A, “Determination of Oxygen and Carbon Dioxide Concentrations in Emissions from Stationary Sources” . The O 2 

## content of the gas stream was measured using a Teledyne paramagnetic O 2 

## gas analyzer. The CO 2 

## content of the gas stream was measured using a Teledyne infrared CO 2 

## gas analyzer. The gas stream was drawn through a stainless-steel probe
with a heated in-line filter to rem ove any particulate, a heated Teflon ® sample line, through a refrigerated Teflon® sample c onditioner to remove the moisture from the sample before it

DTE Belle River Power Plant BTEC Project No. 10-3991.00 Unit 2 Emissions Test Report 8/31/2010 2

## entered the analyzers. Data was recorded on a PC equipped with data acquisition software. Recorded concentrations were averaged and repo rted for the duration of each 120-minute test (as drift corrected per Method 7E). A drawing of the sampling train used for the testing program is presented as Figure 2.

In accordance with Method 7E, a 3-point (zero, mid, and high) bi as check and calibration check was performed on the analyzers prior to initiating the test program. Following each test run, a 2- point (zero and high) calibrati on drift check was performed.

3.3 Sulfur Dioxide (USEPA Method 6C)

The sulfur dioxide content of the gas stream was evaluated according to procedures outlined in Title 40, Part 60, Appendix A, Method 6C. The SO 2 

## content of the gas stream was measured using a Western Research SO 2 

## gas analyzer (see Figure 2 for a schematic of the sampling train). A sample of the gas stream was drawn through an insulated stainless-steel probe with an in-line glass fiber filter to remove any particulate, a heated Teflon ® 

## sample line, through a refrigerated sample conditioner with a peristaltic pump to re move the moisture from the sample before it entered the analyzer. Data was recorded at 4-second intervals on a PC equipped with Labview ® 

## II data acquisition software. Recorded SO 2 

## concentrations were aver aged over the course of each 120-minute test. The analyzer was calibrated for a range of 0 to 500 ppm.

A three-point (zero, mid, and high) ca libration check was performed on the SO 2 

## analyzer. Calibration drift checks we re performed at the completion of each run.

3.4 Carbon Monoxide (USEPA Method 10)
The CO content of the exhaust gas was evalua ted according to procedures outlined in 40 CFR 60, Appendix A, Method 10. The CO content of the gas stream was measured using a TECO 48 CO gas analyzer. The gas stream was drawn thr ough a stainless-steel probe with a heated in-line filter to remove any particulate, a heated Teflon ® sample line, through a refrigerated sample conditioner with a peristaltic pump to remove the mo isture from the sample before it entered the analyzer. Data was recorded on a PC equipped with Labview ® II data acquisition software. Recorded CO concentrations were averaged and reported for the dur ation of each 120-minute test (as drift corrected per Method 7E). The analyzer was cali brated for a range of 0 to 200 ppm.

In accordance with Method 10, a 3- point (zero, mid, and high) calibration check was performed on the CO analyzer. Calibration drift checks we re performed at the completion of each run.

3.5 Formaldehyde (Method 0011)

Exhaust gas formaldehyde concentrations were measured using the pr ocedures of Method 0011, “Sampling For Selected Aldehyde and Ke tone Emissions from Stationary Sources” . The Method 0011 sampling train consisted of: (1) a borosilicate or quartz nozzle, (2) a h eated borosilicate or quartz probe liner; (3) a set of five Greensburg- Smith (GS) impingers with first containing 200 ml of DNPH, (4) the second and third impinge rs each containing 100 mL DNPH, (5) a fourth empty impinger, (6) a modified GS impinger cont aining a known weight of silica gel desiccant;

## (7) a length of sample line, and (6) a Nutech c ontrol case equipped with a pump, dry gas meter, and calibrated orifice. Figure 5 provides an illustration of the Method 0011 sample train.

After completion of the final leak test for each test run, the impinger train was carefully disassembled. The nozzle and probe line were br ushed and rinsed with methylene chloride (MeCl 2 

## ) which was collected in a pre-cleaned samp le container. The liquid volume of each impinger was measured gravimetrically and any mass increase was noted on field sheets. The impinger catch solution was then added to the probe rinse sample container. The impingers were then triple rinsed with MeCl 2 

## and the rinses added to the samp le container. A final rinse with MeCl 2 

## and deionized water (DI H 2 

## O) was performed on the nozzle, probe liner, and impingers.

BTEC labeled each container with the test number, test location, and test date, and marked the level of liquid on the outside of the containe r. In addition, blank samples of the DI H 2 

## O and MeCl 2 

## were collected. Samples were couriered by Maxxam Analytics, Ltd. (Maxxam) personnel to the Maxxam laboratory for analysis.

3.6 Total Hydrocarbons (USEPA Method 25A)

Total hydrocarbons (THC) concentrations were measured according to 40 CFR 60, Appendix A, Method 25A. A sample of the gas stream was draw n through a stainless steel probe with an inline glass fiber filter to remove a ny particulate, and a heated Teflon ® sample line to prevent the condensation of any moisture from the sample befo re it enters the analyzer. Data was recorded at 4-second intervals on a PC equipped with Labview ® II data acquisition so ftware. BTEC used a VIG Model 20 THC hydrocar bon analyzer to determine the THC concentration.

The VIG THC hydrocarbon analyzer channels a fr action of the gas sample through a capillary tube that directs the sample to the flame i onization detector (FID), where the hydrocarbons present in the sample are ionized into carbon. The carbon concentration is then determined by the detector in parts per million (ppm). This c oncentration is transmitted to the data acquisition system (DAS) at 4-second intervals in the form of an analog signal, sp ecifically voltage, to produce data that can be averaged over the durati on of the testing program. This data is then used to determine the average ppm for total hydr ocarbons (THC) using the equivalent units of propane (calibration gas). The analyzer wa s calibrated for a ra nge of 0 to 50 ppm.

In accordance with Method 25A, a 3-point (z ero, mid, and high) calibration check was performed on the THC analyzer. Calibration drift checks were performed at the completion of each run.

3.7 Methane (USEPA Method 18)

Methane concentrations were measured according to 40 CFR 60, Appendix A, Method 18. A tedlar bag was placed inside an integrated ba g sampling lung. A sample of the gas was drawn into the tedlar bag by keep th e lung under negative pressure us ing a pump. Sample extraction was done in conjunction with Method 25A. Integrat ed bag samples were shipped via fed-ex to Enthalpy Laboratories for Methane analysis.

## 3.8 Semi Volatile Organic HAPs (Method 0010)

Method 0010, was used to evaluate semi volatile organic HAP’s concentrations. The Method 0010 sampling train consisted of: (1 ) a stainless steel or borosilicat e glass nozzle, (2) a heated borosilicate or quartz probe liner; (2) a heated bo rosilicate or quartz glass filter holder containing a pre-weighed 90-mm quartz filter with Teflon filter support; (3) a vert ical condenser, (4) a sorbant trap, (5) an empty pot bellied impinger, (6) two Greenburg-Smith (GS) impingers each containing 100 ml of DI H 2 

## O, (7) an empy GS impinger, (8) a modified GS impinger containing a known weight of silica gel desiccant; (9) a length of sample line, and (10) a Nutech control case equipped with a pump, dry gas meter, a nd calibrated orifice. Figure 4 provides an illustration of the Method 0010 sample train.

After completion of the final leak test for each test run, the impinger train was carefully disassembled. The nozzle, probe, and front half of the filter housing were brushed and rinsed with a solvent mixture (1:1 v/v methanol/methyl ene chloride) and collected in a pre-cleaned glass sample container. The filter was recovere d and placed in its original Petri dish. The sorbant trap was removed and capped with para film. The liquid volume of the pot bellied impinger was measured gravimetrically and transfe rred to a glass sample container. The back half of the filter housing, the condenser, and pot bellied impinger were rinsed with the solvent mixture and the rinse was collected in a separa te glass sample container. The remaining impingers were gravimetrically analyzed for mo isture gain and the liquid was discarded.

BTEC labeled each container with the test number, test location, and test date, and marked the level of liquid on the outside of th e container. In addition, blank samples of the solvent mixture, filter, and sorbant trap were collected. Sa mples were couriered by Maxxam personnel to the Maxxam laboratory for analysis.

3.9 Volatile Organic HAPs (Method 0031)

Exhaust gas volatile organic HAPs concentrations were measured using the procedures of Method 0031, “Sampling Method For Volati le Organic Compounds (SMVOC)” . The Method 0031 sampling train consisted of: (1) a heated borosilicate or quartz probe liner; (2) a three way glass/Teflon isolation valve, (3) a vertical conde nser, (4) two Tenax-GC so rbent traps in series, (5) a condensate trap, (6) anothe r vertical condenser, (7) an Anas orb-747 sorbent trap, (8) a small impinger containing a known weight of silica gel de siccant; (9) a length of sample line, and (10) a Nutech control case equipped w ith a pump, dry gas meter, and calibrated orifice. Figure 5 provides an illustration of the Method 0031 sample train.

The probe was placed at the center of the stack for non-isokinetic sampling. The sample train was run for 40 minutes at a rate of 0.5 L/min at which point all the sorben t traps were recovered and replaced with new traps. A to tal of three sets of sorbent traps were used for each test for a total sample time of 120 minutes per test. The mass of liquid condensed in the condensate trap and silica gel impingers were measured gr avimetrically for moisture analysis.

Custody Heather Tarjeft received the samples on 6/23/10 after being relinquished by BT Environmental Consulting, Inc. The samples were received at ambient temperature. The sample, Run 2 had a very low sample volume upon receipt. Prior to, during, and after analysis, the samples were kept under lock with access only to authorized personnel by Enthalpy Analytical, Inc. Analysis The samples were analyzed for methane using the analytical procedures in EPA Method 18, Measurement of Gaseous Organic Compound Emissions by Gas Chromatography (40 CFR Part 60, Appendix A). The standards and samples were analyzed following the procedures specified in section 8.2.1, Integrated Bag Sampling and Analysis. All samples and standards were introduc ed directly to the column using an automated 6-port Valco gas sampling valve equipped with a stainless steel loop. Methane was referenced to certified gas phase standards. The Agilent Technologies Model 6890, Gas Chromatograph ("Gummo" S/N US00028451) was equipped with a Fl ame Ionization Detector and a Restek Rtx-624, 30 m x 0.32 mm column (S/N 926828).

Calibration The calibration curves are located in the back of this report and referenced in the Analysis Method column on the Detailed Results page. For each calibration curve used, the first page of the curve contains all method specific parameters (i.e., curve type, origin, weight, etc.) used to quantify the samples. The calibration curve section also includes a table with the Retention Time (Ret Time), Level (Lvl), Amount (corresponding units), Area, Response Factor (Amt/Area) and the analyte Name. The calibration table is used to identify (by retention time) and quantify each target compound.

Chromatographic Conditions The acquisition method gc114p103.m is included in the Calibration Curve Chromatograms section of this report.

# Enthalpy Analytical Narrative Summary (continued)

QC Notes As required by section 8.4.2, Recovery Study for Bag Sampling, a recovery study is performed on a bag sample. The bag sample Run 1 was spiked at 11:30 AM on 6/24/10. Th e recovery efficiency value met the method-required limit of between 70 and 130%. The recovery efficiency value is used to adjust the results following equation 18-7 from section 12.8. A Laboratory Control Sample (LCS) bag was analyzed with the samples. The recovery value was 89.2%. All sample preparation and analytical holding times specified in the method were met. Reporting Notes The results presented in this report are representative of the samples as provided to the laboratory. These analytical results are reported on a wet basis. The user of this report should determine the % moisture in the sample and correct the reported value to ppmvd as appropriate. There was only one injection made for Run 2 as there was not enough volume for any more injections. Enthalpy Analytical, Inc. is accredited to perform this method for compliance purposes by the National Environmental Laboratory Accreditation Conference (NELAC) through the Louisiana Environmental Laboratory Accredita tion Program (LELAP), certificate number 04010.

# General Reporting Notes

The following are general reporting notes that are applicable to all Enthalpy Analytical, Inc. data reports, unless specifically noted otherwise.

The acronym MDL represents the Minimum Detection Limit. Below this value the laboratory cannot determine the presence of the analyte of interest reliably. The acronym LOQ represents the Limit of Quantification. Below this value the laboratory cannot quantitate the analyte of interest within the criteria of the method. The acronym ND following a value indicates a non-detect or analytical result below the MDL.
The letter J following a value indicates an analytical result between the MDL and the LOQ. A J flag indicates that the laboratory can positively identify the analyte of interest as present, but the value should be considered an estimate.
The letter E following a value indicates an analytical result exceeding 100% of the highest calibration point. The associated value should be considered as an estimate. The acronym DF represents Dilution Factor. This number represents dilution of the sample during the preparation and/or analysis process. The analytical result taken from a laboratory instrument is multiplied by the DF to determine the final undiluted sample results.
The addition of MS to the Sample ID represents a Matrix Spike. An aliquot of an actual sample is spiked with a known amount of analyte so that a percent recovery value can be determined. This shows what effect the sample matrix may have on the target analyte, i.e. whether or not anything in the sample matrix interferes with the analysis of the analyte(s).
The addition of MSD to the Sample ID represents a Matrix Spike Duplicate. Prepared in the same manner as an MS, the use of duplicate matrix spikes allows further confirmation of laboratory quality by showing the consistency of results gained by performing the same steps multiple times.
The addition of LD to the Sample ID represents a Laboratory Duplicate. The analyst prepares an additional aliquot of sample for testing and the results of the duplicate analysis are compared to the initial result. The result should have a difference value of within 10% of the initial result (if the results of the original analysis are greater than the LOQ).
The addition of AD to the Sample ID represents an Alternate Dilution. The analyst prepares an additional aliquot at a different dilution factor (usually double the initial factor). This analysis helps confirm that no additional compound is present and coeluting or sharing absorbance with the analyte of interest, as they would have a different response/absorbance than the analyte of interest. The Sample ID LCS represents a Laboratory Control Sample. Clean matrix, similar to the client sample matrix, prepared and analyzed by the laboratory using the same reagents, spiking standards and procedures used for the client samples. The LCS is used to assess the control of the laboratory’s analytical system. Whenever spikes are prepared for our client projects, two extra spikes are prepared. The extras (randomly chosen) are labeled with the associated project number and kept in-house at the appropriate temperature conditions. When the project samples are received for analysis, the LCSs are analyzed to confirm that the analyte could be recovered from the media, separate from the samples which were used on the project and which may have been affected by source matrix, sample collection and/or sample transport.

# General Reporting Notes
(continued)

Significant Figures : Where the reported value is much greater than unity (1.00) in the units expressed, the number is rounded to a whole number of units, rather than to 3 significant figures. For example, a value of 10,456.45 ug catch is rounded to 10,456 ug. Ther e are five significant digits displayed, but no confidence should be placed on more than two significant digits. Manual Integration : The data systems used for processing will flag manually integrated peaks with an “M”. There are several reasons a peak may be manually integrated. These reasons will be identified by the following two letter designations. The peak was not integrated by the software “NI” , the peak

was integrated incorrectly by the software “II” or the wrong peak was integrated by the software “WP” . These codes will accompany the analyst’s manual integration stamp placed next to the compound name.

GENERAL COMMENTS

ABNMM5-TR

Benzoic acid and Benzidine are above 20% RSD in initial calibration.

Benzidine is above 30% RSD in 8270 Reference Standard.

PAHMM5-TR 7,12-Dimethylbenzo(a)anthracene is above 25% RSD in initial calibation and D8-Acenaphthylene is above 25% RSD in continuing

. No positive found for this compound.

Not calibrated for Benzo(b)Anthracene, Picene, Dibenzo(a,c) anthracene or Triphenylene. An estimated mdl for each of these compounds is 0.15ug. Since Dibenzo(a,c) anthracene co-elutes with Dibenzo(a,h) anthracene and Triphenylene with Chrysene each would have a value below estimated mdl. Benzo(b)Anthracene elutes after Benzo(a)Anthracene and Chysene. Picene elutes after Dibenzo(a,h) anthracene. Searched for ions specific to these 2 compounds in the appropriate retention time range with no possible positives detected

Sample GH4657-01: ABNMM5-TR

Low recovery of 2,6-Dibromo-4-fluorophenol and 2,4,6-Tribromophenol in this sample.

Sample GH4660-01: ABNMM5-TR

Internal Std area response criteria was low in this sample. The sample was rerun with similar result. Original run reported.

Sample GH4663-01: ABNMM5-TR

Sample was rerun at a 2x dilution for Benzoic acid due to exceedence of linear range. Mdl was raised accordingly.

Results relate only to the items tested.
