## 1.0 Introduction

BT Environmental Consulting, Inc. (BTEC) was re tained by DTE Energy (D TE) to evaluate air pollutant emissions rates from Monroe Power Plant Unit 3 (MONPP Unit 3) located in Monroe, Michigan. The test project cons isted of (1) measurement of exhaust gas flowrates and moisture content, (2) measurement of exhaust gas oxygen (O 2 

## ) and carbon dioxide (CO 2 

## ) concentrations, (3) measurement of exhaust gas dioxin and fura n concentrations and emission rates, and (4) measurement of fuel sample higher heating value. Testing for this project was completed during the period beginning June 29 and ending July 1, 2010. The emissions test program was requested in a letter sent to DTE by the United States Environmental Protection Agency (U.S. EPA) pursuant to U.S. EPA authority under Section 114 of the Clean Air Act.

The following BTEC professionals participated in conducting this study: Thom Snyder, Project Manager; Jon Beach, Staff Environmental En gineer; and Matthew Smith, Environmental Technician. Mr. Mark Grigerit e with DTE provided on-site coordination for this project.

2.0 Process Description

The Monroe Power Plant (MONPP) located at 3500 E. Front Street in Monroe, Michigan, employs the use of four (4) Babcock and Wilcox co al-fired boilers (Units 1-4) each designed to produce nominally 5,717,865 pounds per hour of steam. Units 1 and 4 have a General Electric turbine generator with a rated capability of 817 gross megawatts (GMW). Units 2 and 3 have Westinghouse turbine generators each with a rated capability of 823 GMW. Units 1 and 2 exhaust into a common stack (Stack 1). Unit 3 and Unit 4 exhaust into individual stacks. The typical coal blend for Unit 3 is a 65% low-su lfur western (LSW) / 35% mid-sulfur eastern (MSE). Full load conditions fo r the Unit will be nominally 740-785 MW, but may be lower during the testing period due to unit-specific issu es. Testing will occur on Unit 3 as close to full load conditions as possible, but not less than 90% of full load.

3.0 Sampling and Analytical Methodologies

Sampling and analytical methodologies for the em issions test program can be separated into three 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 dioxin/furan HAP concentrations and emission rates using U.S. EPA Method 23.

Descriptions of sampling and analytical methodologies by category are su mmarized by Sections 3.1 through 3.3, respectively.

DTE Monroe Power Plant BTEC Project No. 10-3991.01 Unit 3 Emissions Test Report 8/31/2010 1

## 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 eachsample 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 23 sampling train (see Figure 3 for a schematic of the sampling train). Exhaust gas moisture content 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 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 480-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 4-point (zero, low, mid, and hi gh) bias check and calibration check was performed on the analyzers prior to in itiating the test program . Following each test run, a 2-point (zero and high) calibration drift check was performed.

## 3.3 Dioxin/furan HAP (USEPA Method 23)

40 CFR 60, Appendix A, Method 23, “Determination of Polychlo rinated Dibenzo-p-dioxins and Polychlorinated Dibenzofurans from Municipal Waste Combustors” was used to evaluate dioxin/furan HAP concentrations. The Method 23 sampling train consisted of (1) a borosilicate glass or quartz nozzle, (2) a steel probe w/ glass liner, (3) a heated quart z fiber filter assembly, (4) a glass recirculating ice wate r condenser system, (5) a XAD-2 sorbent trap, (6) an empty pot bellied impinger, (7) a set of five GS impingers , (8) a length of sample line, and (9) a Nutech ® control case equipped with a pump, dry gas meter, a nd calibrated orifice. Prior to each test, the second and third impingers were filled with 100 ml of HPLC water, the first and fourth impingers were empty, and the fifth impinger contained approximately 300 g of silica gel desiccant. A schematic drawing of the D/F sample train is provided as Figure 3.

After completion of the final leak test for each test run, the impinger train was carefully disassembled. The liquid volume of each impinger was measured gravimetrically and any mass increase was noted on field sheets. The adsorb ent module was removed from the sampling train, tightly capped at both ends, labeled, covered with al uminum foil, and stored in an iced cooler for later transport to the laboratory. The filter was recovered and placed in its original Petri dish. The nozzle, probe, filter housing, and condenser were brushed and triple rinsed with acetone and then methylene chloride (MeCl 2 

## ) which was collected in a pre-cleaned sample container. The nozzle, probe, filter housing, and condenser were then triple rinsed with toluene which was collected in a separate sample container.

BTEC labeled each container with the test number, test location, and test date, and marked the level of liquid on the outside of the container. In addition, bla nk samples of the HPLC water, acetone, MeCl 2 

## , toluene, adsorbent module, and filter were collected. Samples were couriered by Maxxam Analytics, Ltd. (Maxxam) personnel to the Maxxam laboratory for analysis.

Duplicate: Paired analysis of a separate portion of the same sample. Used to evaluate the variance in the measurement. Spiked Blank: A blank matrix to which a known amount of the analyte has been added. Used to evaluate analyte recovery. Method Blank: A blank matrix containing all reagents used in the analytical procedure. Used to identify laboratory contamination. Surrogate: A pure or isotopically labeled compound whose behavior mirrors the analytes of interest. Used to evaluate extraction efficiency. NC (RPD): The RPD was not calculated. The level of analyte detected in the parent sample and its duplicate was not sufficiently significant to permit a reliable calculation. ( 1 ) EMPC /

NDR - Peak detected does not meet ratio criteria and has resulted in an elevated detection limit.
