# Executive summary

On January 22, 2009 an Administrative Order by Consent ("Agreed Order") was executed between the Minnesota Pollution Control Agency ("MPCA") and ArcelorMittal Minorca Mine, Inc. ("ArcelorMittal") outlining a procedure for generating data on NOx emissions from the pellet furnace (Emission Unit EU026 from Air Emissions Permit No . 13700062-002) . MPCA has determined that it needs NOx emissions data from taconite ore processing facilities to complete its determination of Best Available Retrofit Technology (BART) requirements under the Regional Haze Rule (40 CFR 51.300 - 51 .309). MPCA asked that ArcelorMittal agree to monitor nitrogen oxides ("NOx ") emissions from its pellet furnace over an extended period of time (at least 150 hours of data) and under a range of operating conditions that may influence NOx emissions . ArcelorMittal agreed to conduct an extended NOx test to generate the data required to justify an " Alternative Method" for monitoring NOx emissions in the future without installing continuous emission monitors for NOx. The Agreed Order established the testing procedure and a method for calculating the relative variability index ("RVI ") . If the RVI during testing was low (.:s0 .20), ArcelorM ittal's proposed Alternative Method would merely track relevant operating parameters to demonstrate that NOx emissions remained comparable to the rate established during the test. Every two years thereafter, ArcelorMittal would verify the NOx emission rate when conducting the standard 3-hour stack test currently required in its operating permit. A high RVI during testing would require a more elaborate Alternative Method using a predictive equation to translate relevant operating parameter data into calculated NOx emissions . The predictive equation would be calibrated with an annual EPA Method 7E test. The test data from the extended NOx test generated a low RVI of 0.16. This Report satisfies ArcelorMittal's initial data collection and reporting obligations set forth in sections 9 and 10 of the Agreed Order. Section 9 requires that ArcelorMittal submit a Plan for gathering and analyzing the data for the Alternative Method. With MPCA 's knowledge and approval, ArcelorMittal moved forward with the NOx testing in advance of the final Agreed Order. Thus, the Test Plan to satisfy Section 9 was originally submitted to MPCA prior to the March 2008 test period and, after discussions between ArcelorMittal and MPCA about the Plan, MPCA issued a Plan approval letter dated March 6, 2008. The Plan documents satisfying Section 9 of the Agreed Order are attached as Appendix G.

# Introduction
Barr Engineering conducted nitrogen ox ides (NO x) emissions testing at ArcelorMittal Minorca Mine, Inc. (ArcelorMittal) located in Virginia, Minnesota. The test was performed to evaluate the variability of NO x emissions as it relates to the normal operation of taconite production. The test simultaneously measured the NO x concentration and volumetric air flow rates from the four indurating furnace waste gas stacks for a total of 157 valid hours. A test plan dated February 8, 2008 was submitted to the Minnesota Pollution Control Agency (MPCA). A pretest meeting was held on March I with representatives of ArcelorMittal, Barr Engineering and Andy Place of the MPCA. A copy of the test plan and the test plan approval letter issued by MPCA on March 6, 2008 are provided in Appendix G. The testing was performed in response to the proposed Administrative Order by Consent ("Agreed Order") between the MPCA and ArcelorMittal. The Agreed Order addresses the U.S. Environmental Protection Agency regulations on visibility impairment for Class I wilderness areas referred to as the Regional Haze Rule (40 CFR part 51.300-51.309) . The rule identifies key pollutants that contribute to regional haze such as particulate matter, sulfur dioxide (SOz) and NO x. To help MPCA evaluate NO x emissions for defining the Best Available Retrofit Technology (BART), ArcelorMittal agreed to collect NO x data from the furnace waste gas stacks using an extended Method 7E test procedure designed to determine the relative variability of NO x emissions during normal operating conditions. The alternative method defined in the Agreed Order details the testing requirements for data collection in support of the NO x relative variability index (RVI) calculation . Testing was performed as required with method exceptions defined in the test plan and test plan approval letter. During the test, the indurating furnace was operated under normal operating conditions . The process operating data is provided in Appendix F . Pete Rossmiller and Aaron Aamold of Barr Engineering performed the NO x testing. Jaime Baggenstoss and Jon Maki of ArcelorMittal coordinated the test team and facility operations. Though provided notice and an invitation to attend, MPCA chose to not witness the test. A Iist of project participants is provided in Appendix H.

# Results Testing of ArcelorM ittal' s pellet indurating furnace waste gas stacks began on March 11, 2008 and continued until March 22, 2008. ArcelorMittal has two standard ore blends, LC5 / UCI and LC4 / UC3. On March 6, ArcelorMittal introduced the LC5 / UC lore blend. This meant that some LC4 / UC3 ore was still in the fine ore stockpile during the course of the NOx study . These different blends process differently. By processing the two different ore blends during the test period, ArcelorMittal increased the potential variability of the study. The primary variables identified in the test plan include the green pellet feed rate (GP2), gas flows to the chambers and preheaters, firing chamber temperatures and the pellet tonnage . In an effort to establish target operating ranges during the extended testing, process data between January 1, 2002 and March 2, 2008 for days greater than 23.5 hours of operation was used. Two standard deviations from the average were used as the desired operating target range for the Extended Method 7E test period. Table 2 demonstrates that the average values for the key parameters fell within the desired ranges during the extended testing. Since reclaimed pellets can affect the pellet rates, GP2 can be the best indicator of feed to the grate. Other secondary operating parameters that were monitored during the testing include burn-through temperature , bed depth , fan horsepower, firing chamber temperatures, and others as indicated in Appendix F. Data was considered valid when all four analyzer systems were operating correctly and simultaneously. It was agreed in the MPCA pretest meeting that a minimum of forty-five minutes of valid data in an hour would be used to represent one hour of valid data. This allowed normal daily analyzer drift checks and system bias checks to be performed without invalidating an hourly data point as long as the procedure could be completed in fifteen minutes or less. Similarly, when sample gas filters required changing, the procedure was normally completed in less than fifteen minutes. These events are identified in the data set. The data collection system used during the test experienced an occasional fault. During the fault event, the system recorded an invalid value for each parameter during a single ten second averaging period . This error occurred nine times during the eleven days of testing. In cases where it was obviously a data collection error, the minute including the error was excluded and the fifteen-minute average was calculated using fourteen minutes of unaffected data . The result has a minimal effect on

## the data as only one minute out of sixty minutes during each affected hour was excluded . Affected hours meet the criteria for a valid hour of data (45+ minutes). There was a significant interruption of data collection due to a plant breakdown. The interruption occurred with a plant shutdown on March 14 at 6:30 p.m. and continued until the plant was restarted and the furnace process stabilized on March 17 at 5:00 p.m. The MPCA was contacted about the delay and it was agreed that the Extended Method 7E testing could continue when the plant resumed operation. Intermittent problems occurred with the testing company's airflow measuring equipment. Several times moisture migrated into the pitot lines and froze giving false readings . Affected data was flagged when the problem appeared until the problem was corrected . These issues were discussed with Andrew Place and MPCA agreed that testing should continue until an excess of 150 hours of valid data had been collected. Periods of process shutdown and invalidated hours due to instrument failure are identified in the dataset. A copy of the data file 

## NOx test data 

## 3-11 through 3-22-08 values.xis is provided in an unlocked electronic spreadsheet on a CD with this report. This dataset contains all of the test data and emission rate calculations. The one-hour data provided is calculated using fifteen-minute averages. Hard copies of the data were not printed due to the large volume of data. The relative variability index is calculated as described in the Agreed Order using 157 one-hour data points and is summarized in Table 1. The calculated RVI is 0.16 which is below (less than) the MPCA defined maximum RVI of 0.20 for low variability for NO x emissions.

## 7 the data as only one minute out of sixty minutes during each affected hour was excluded. Affected hours meet the criteria for a valid hour of data (45+ minutes). There was a significant interruption of data collection due to a plant breakdown. The interruption occurred with a plant shutdown on March 14 at 6:30 p.m. and continued until the plant was restarted and the furnace process stabilized on March 17 at 5:00 p.m. The MPCA was contacted about the delay and it was agreed that the Extended Method 7E testing could continue when the plant resumed operation. Intermittent problems occurred with the testing company's airflow measuring equipment. Several times moisture migrated into the pitot lines and froze giving false readings . Affected data was flagged when the problem appeared until the problem was corrected. These issues were discussed with Andrew Place and MPCA agreed that testing should continue until an excess of 150 hours of valid data had been collected. Periods of process shutdown and invalidated hours due to instrument failure are identified in the dataset. A copy of the data file

# Process description
ArcelorMittal mines taconite ore (magnetite) and produces flux iron-bearing peIlets. The peIlets are then shipped to ArclorMittal Indiana Harbor's No.7 Blast Furnace . The emission sources tested capture the waste gases from the peIlet indurating process . Concentrate slurry flows to a storage tank where limestone is added to make flux peIlets. The concentrate is dewatered by vacuum disk filters , mixed with bentonite and conveyed to baIling disks . Green balls produced on the baIling disks are transferred to a roIl conveyor for additional removal of over and undersize material. The green balls are distributed evenl y across paIlet cars, prior to entry into the peIlet furnace . The pallet cars have a layer of fired pellets, called the hearth layer, on the bottom and sides of the car. The hearth layer acts as a buffer between the pallet car and the heat generated through the exothermic conversion of magnetite to hematite. There is one natural gas -fired furnace at ArcelorMittal's taconite plant. The straight grate furnace has several distinct zones. The first two stages are updraft and downdraft drying zones. The next zones are the preheat zone and firing zone. The temperature increases as the peIlets pass through each zone reaching a peak in the firing zone. The peIlets enter the after-firing zone, where the conversion of magnetite to hematite is completed. The last two zones are cooling zones that aIlow the peIlets to be discharged at a temperature of around 120 degrees Fahrenheit. Heated air discharged from the two cooling zones is recirculated to the drying, preheat and firing zones. Off-gases from the furnaces are vented primarily through two ducts , the hood exhaust which handles the drying and recirculated cooling gases , and the windbox exhaust which handles the preheat, firing, and after-firing gases . The windbox exhaust flows through a multiclone, which protects the downstream fan, and then enters a common header shared with the hood exhaust stream. The exhaust gases are subsequently divided into four streams which lead to four, venturi rod scrubbers and exhaust from individual stacks .

# Stack testing procedures and methods
The testing was performed from ports meeting EPA Method I criteria. Test port location and full traverse drawings are provided in Figures I and 4. An initial airflow using an S-type pitot was performed using EPA Method 2 criteria at each stack. An S-type pitot tube was fixed at the point in the stack most representative of the average differential pressure. A calibrated Dw yer Magnesense gauge was used to read the differential pressure at this point. Calibrated type " K" thermocouples were positioned in the stack to measure stack temperature . The stack static pressure was measured daily. Calculations of volumetric airflow were made with fifteen-minute average data values for velocity pressure, temperature , barometric pressure , oxygen and carbon dioxide. Stack gas moisture was measured using an approximation method (wet bulb-dry bulb technique) from EPA Method 4. Several daily readings indicated that wet bulb temperatures were consistently one degree Fahrenheit less than dry bulb temperatures; therefore all subsequent moistures were calculated assuming a wet bulb value one degree less than the measured dry bulb value. The oxygen and carbon dioxide concentrations of the stack gas were measured at one stack continuously during the testing, with daily measurements made at the other three stacks. The 

## 02/C02 analyzer was calibrated per EPA Method 3A and was fed a split gas stream off the NO x system. The oxygen and carbon dioxide concentrations used for calculation of gas stream molecular weights for the three stacks which had only spot checks were performed using the average of the two readings on either end of the data set. Nitrogen oxides concentrations were determined using a modified EPA Method 7E. Protocol I gas standards were used for daily instrument calibration, system bias checks , and calibration drift checks. Analyzers were calibrated at the beginning of the project and after the plant shutdown. No intermediate instrument calibration adjustments were needed as drift and calibration error remained within specifications of the method . The upper span gas used to calculate maximum drift and system bias was 462 ppm NO x . The MPCA agreed to accept data within 7.5 percent system bias error but application of that allowance was not needed. The system bias calibrations were performed at least once each day and these calibration results were used to bias correct the raw NO x averages between calibration times.
