# Introduction

Barr Engineering performed continuous nitrogen oxides (NO„) emissions testing at Northshore Mining Company located in Silver Bay, Minnesota. The Furnace 11 testing was conducted between July 26-28, 2010 and the Furnace 12 testing occurred from July 29-30, 2010.
The testing was performed in accordance with the Administrative Order by Consent voluntarily entered into by Northshore Mining and the Minnesota Pollution Control Agency on April 7, 2008. Recurrent annual stack testing is part of Northshore's June 2008 Alternative Method Proposal that is used to demonstrate current NOx emissions from the facility. During the tests, the indurating furnaces were operated under normal conditions.
A test plan dated July 15, 2010 was submitted to the Minnesota Pollution Control Agency (MPCA). A pretest meeting was held on July 19, 2010 with representatives of Northshore Mining Company, Barr Engineering and Andy Place of the MPCA. A copy of the test plan and the test plan approval letter issued on July 20, 2010 are provided in Appendix F. Testing was performed as required with method exceptions defined in the test plan and test plan approval letter.
Barr Engineering performed the NO testing with Jennifer Ramsdell of Northshore Mining Company coordinating the test team and facility operations. The tests were not witnessed by a MPCA representative. A list of project participants is provided in Appendix G.
At least 30 hours of valid one-hour NOx emission data points were required from each Waste Gas stack, There were 36 hours of valid data collected on Line 11 and 33 hours on Line 12. NO emissions were measured simultaneously from the two indurating furnace Waste Gas stacks at each furnace line.

# Results

Testing of Northshore Mining Company's Furnace 11 resulted in a total of 36 valid one-hour data points collected and Furnace 12 resulted in a total of 33 data points.
Data was considered valid when all the analyzers/systems were operating correctly and simultaneously. It was agreed in the MPCA pretest meeting that forty-five minutes of data in an hour could be used to represent one hour of valid data. This would allow normal daily analyzer drift checks and system bias checks to be performed without omission of data provided the procedure could be completed in fifteen minutes.
Periods where process problems, equipment issues or calibrations occurred are flagged appropriately in the results tables. If these occurrences happened within a fifteen minute period, the 45 minutes of valid data within the hour is used to represent the one-hour average. These events where 45 minutes of valid data are used to represent a one-hour average are further identified in the data set with an "R" flag.
The stack temperatures were also recorded and used to calculate the moisture content of the stacks. Moisture content of the stack gas is determined by calculating the saturated value using the average stack temperature for each hour. These sources have continuous airflow monitors that record in actual cubic feet per minute (acfm) and these data are used with the moisture content and barometric pressure to calculate a dry standard cubic feet per minute (dscfm) airflow rate. The dscfm and NOx concentrations are used to calculate the pound per hour (lb/hr) emissions from each stack. Hourly emission rates are shown in Tables 1 and 2.

# Process Description

Northshore's No. 11 and No. 12 Pelletizers are second generation straight grate furnaces manufactured by Arthur G. McKee Company and were installed in 1962. Each furnace has four major operating zones referred to as the drying zone, pre-heat zone, firing zone and the cooling/recoup zone.
Unfired green balls comprised of iron concentrate and bentonite enter the furnace at the drying zone. A layer of previously fired pellets is placed on the grate (hearth layer) and the green balls are then placed on the hearth layer at the furnace entrance. The green balls are then dried using heat recouped from the furnace. The air from the drying zone is directed to the Hood Exhaust.
The dried pellets enter the firing zone where they are heated sufficiently to start an exothermic reaction caused by conversion of the magnetite to hematite. Natural gas burners are located in the firing zone for providing the necessary heat. The waste gas is exhausted from the firing zone.
Once the exothermic reaction is started the pellets enter the cooling/recoup zone where the exothermic reaction of the pellets is completed and the reacted pellets are cooled before exiting the furnace. The hot exhaust from this zone is recouped for furnace operation and the excess enters the Hood Exhaust.
Furnace 11 and 12 hood exhaust and waste gas streams are directed to wet wall electrostatic precipitators (WWESP) for emissions control. The waste gas is split evenly between two WWESPs (CE104, CE105 and CE114, CE115). The hood exhaust is directed to three parallel WWESPs (CE101-103 and CE111-113).
Operating parameters of the Furnace 11 and Furnace 12 were recorded every hour for the duration of the tests and are located in Appendix E.

# Sampling and Analysis Procedurnc

The testing was performed from ports meeting EPA Method 1 criteria. Test port location drawings are provided in Figures 1-2.

Data from the continuous airflow monitors (acfm) were used with the saturated moisture content of the average stack temperature and the barometric pressure to determine the dscfm airflow rates. The continuous airflow monitors were verified at least once per stack during each 30-hour test period using EPA Method 2.
Nitrogen oxides concentrations were determined using a modified EPA Method 7E. EPA Protocol gas standards were used for daily instrument calibration, system bias checks, and calibration drift checks. Analyzers were calibrated at the beginning of each furnace line test. Intermediate instrument calibration adjustments were not needed as drift and calibration error remained within specifications of the method. The upper span limit used to calculate maximum drift and system bias was 244 ppm NO for the Waste Gas stacks. The MPCA agreed to accept data within 7.5 percent system bias error, but application of that allowance was not needed. System bias calibrations were performed prior to testing and at the completion of the testing at a minimum. Final NO x averages are not bias corrected.
A Campbell Scientific CR1000 with multiplex board data logger system was used to record the output signals from the stack thermocouples and NO analyzers. The data logger was programmed to collect data every ten seconds and generate one-minute and 15-minute averages. Four fifteen-minute averages collected by the data logger were used to calculate one-hour averages. The average of the three valid fifteen minute readings is used to represent a one-hour average when only one fifteen minute period within the hour is invalid. If there is more than one fifteen-minute period with invalid data during one hour due to process or equipment problems, the resulting hourly average is flagged appropriately in the results tables.
U. S. EPA test Methods 1, 2, and 7E are found in 40 CFR Part 60, Appendix A. Calibration documentation for the instruments is provided in Appendix C. Copies of the gas certification analyses are provided in Appendix D.

### Part 

## IV: Test Methods All tests will be performed using the following USEPA reference test methods.

Test Methods for NOx Testing on the Waste Gas Stacks (30-hrs) 

### Modified Method 1 One sample point will be used to collect the gas sample for NOx and 02/002 analysis.

Airflow Rate The continuous airflow rate monitors that are in stalled on the stacks will be used to obtain the airflow rates of each stack. These results will be corrected for the saturated moisture content of the stack to determine the dry standard airflow rate. If the airflow rate monitors are not available during.the time of the NOx testing, the following procedures will be used. An "S" type pitot tube fixed at a representative single point in each stack. A full traverse of the stack will be recorded (once at each stack vent) and a correction factor will be made based on the average differential pressure readings from the full traverse to correct any bias from the single point readings. Differential pressure recorded with one minute and one hour averages in inches of water. (30 1-hr data points for each stack vent) Stack temperature using a type K thermocouple, recorded with one minute and one hour averages in gF. (30 1-hr data points for each stack vent) Modified Method 4 Determination of Moisture Content in Stack Gases. Wet bulb/dry bulb readings will be taken to verify saturated stack conditions. Further moisture calculations will assume saturation at the average stack temperature. Method 7E Determination of Oxides of Nitrogen Emissions from Stationary Sources. The measurement of NOx concentration will be performed at each of the Waste Gas stacks and will be performed following Modified EPA Method 7E and OEM guidelines. The method performance will be modified by collecting data over 30 hours of representative plant operation. Chemiluminescent NO/NO x analyzers will be used to determine NOx concentrations on a dry basis. All analyzers will be calibrated initially for linearity and the NO 2 converter efficiency check will be conducted with a NIST traceable NO2 in N2 

### balance calibration gas. Daily system bias calibrations with zero and span calibration gases. All Method 7E calibration criteria will be met except that a system bias of up 7.5% of span will be used for the upper limit of acceptability for data validating. If the bias calibration results are greater than 5% the analyzer will be recalibrated for linearity and system bias will be checked again. A span range of -250 ppm is expected for the Waste Gas stacks. Following OEM data guidelines any one hour data point is considered valid if 45 minutes of data during that hour is valid, the average of the valid data will be used for that hour's average. Therefore calibration time completed within 15 minutes/system will result in no data loss time. Data will be used like CEM data. No bias correction will be done to the raw concentration recordings.



## Part V: Continuous Emissions Monitors There are no continuous emissions monitors that are germane to this test.

Northshore Mining Company Page 3 of 4
