# Introduction

Barr Engineering conducted performance tests at Northshore Mining Company located in Silver Bay, Minnesota. Tests were conducted on the Concentrator Bin — Section 9 (SVO40) and Furnace 5 (EU634) Hood Exhaust/Waste Gas Stacks —501, 502, 503 (SV266, SV267, SV268). Testing at each source included particulate matter (PM) determinations to be used in determining compliance with the 40 CFR Part 63 Subpart RRRRR "Taconite Iron Ore Processing" MACT standards. One test at the Furnace 5 Hood Exhaust/Waste Gas — 501 included determining the sulfur dioxide emissions. Total particulate matter (TPM) and particulate matter less than 10 microns (PM 10 ) determinations were also made on the Furnace 5 Hood Exhaust/Waste Gas — 503 (SV268) to fulfill the performance testing requirements for the Pellet Indurating Furnaces (GPO 14) in Air Emission Permit No. 07500003-004.
Testing was performed on August 26-28, 2008 by Mark Petersen and Aaron Aamold of Barr Engineering. Scott Gischia provided the coordination of the test team and facility operations. The MACT notification was submitted on February 15, 2008. The test plan was submitted to the Minnesota Pollution Control Agency (MPCA) on July 28, 2008 and discussed on August 22, 2008. The stack testing was not witnessed by a representative of the MPCA. A list of project participants is provided in Appendix G and a copy of the stack test plan with the approval letter is provided in Appendix F.

Each test consisted of three 120-minute test runs. Particulate matter (PM) was determined at each source to be used in demonstrating compliance with the 40 CFR Part 63 Subpart RRRRR "Taconite Iron Ore Processing" MACT. Sulfur dioxide (SO 2 ) was determined in conjunction with the PM test on Furnace 5 Hood Exhaust/Waste Gas — 501 (SV266). Total particulate matter (TPM) and particulate less than 10 microns (PM io ) was determined in conjunction with the PM test on Furnace 5 Hood Exhaust/Waste Gas — 503 (SV268). The SO 2 , TPM and PK () determinations were made to fulfill the performance testing requirements for the Pellet Indurating Furnaces (GPO 14) in Air Emission Permit No. 07500003-004 after the start-up of Furnace 5 (EU634). EPA Methods 5 and 202 were used to determine total particulate emissions (TPM). Results reported here in the text of the report are in the same units as the more stringent associated pollutant limitations. The TPM results represent the dry catch (filterable) plus the organic condensibles. All sample fractions (dry catch, organic condensibles, aqueous phase condensibles (inorganics)) were determined and assumed to equal particulate matter less than 10 microns (PMio).

Test results are presented in the following section. Field and laboratory data along with supporting documentation is located in the appendices.

# Summary of Results
Particulate results are reported as PM (dry catch only); TPM — total particulate matter (dry catch plus organic condensibles) and PM io (dry catch plus organic and aqueous phase condensibles). Only the applicable particulate emissions and the more stringent limit are discussed in this section, when applicable standards apply.



## Concentrate Bin — Section 9 (SVO40) Table 1 summarizes the results with the resulting average PM concentration of 0.0016 grains per dry standard cubic foot (GR/DSCF). The airflow rate during the test averaged 30,400 DSCFM and the ore throughput rate at the rod mill during the test averaged 121 long tons per hour (ltph).



## Furnace 5 Hood Exhaust/Waste Gas — 501 (SV266) Table 2 summarizes the results with the resulting average PM concentration of 0.009 grains per dry standard cubic foot (GR/DSCF). Sulfur dioxide (SO 2 ) was also determined to be 6.8x10 -8 pounds per dry standard cubic foot, resulting in an emission rate of 0.0071 pounds per million British thermal units (1b/M1VIBtu). This SO 2 emission rate is less than the permitted limit of 0,072 lb/MMBtu. The airflow rate during the test averaged 52,200 dry standard cubic feet per minute (DSCFM).



## Furnace 5 Hood Exhaust/Waste Gas — 502 (SV267) Table 3 summarizes the results with the resulting average PM concentration of 0.011 GR/DSCF. The airflow rate during the test averaged 50,800 DSCFM.



## Furnace 5 Hood Exhaust/Waste Gas — 503 (SV268) Table 4 summarizes the results with the resulting average PM concentration of 0.0086 GR/DSCF. The airflow rate during the test averaged 56,200 DSCFM. TPM and PM io were also determined on this source for Title V purposes. The TPM concentration averaged 0.009 GR/DSCF with an emission rate of 0.0012 lb/MMBtu. These are less than the permitted limits of 0.01 GR/DSCF and 0.18 lb/MMBtu. PM10 concentrations averaged 0.012 GR/DSCF, which is less than the permitted emissions limit of 0.020 GR/DSCF.



## Flow-weighted Mean Concentration The flow-weighted mean concentration using equation 4 in 40 CFR Part 63.9621 (c)(3) result is 0.01 GR/DSCF, as shown in Table 5. This meets the 'Taconite' MACT standard of 0.01 GR/DSCF for a "Straight grate indurating furnace processing magnetite".

During test run one on the Furnace 5 Hood Exhaust/Waste Gas —501 and 503, the circuit breaker for the sampling equipment was tripped and caused a delay. Once power was secured the sampling was continued from the point where it was interrupted. During the delay it was also noticed that the power grids were still on and the desired testing

5

## condition was to have them off. The power grids were turned off at this point, but the run was not restarted because of this. No other irregularities or difficulties where encountered during the tests.

# Process Description

The fine crushed ore used in the concentrators is stored in Concentrator Storage Bins for each concentrator section (rodmill sections). During the test period Section 9 rodmill throughput averaged 121 long tons of ore per hour. The concentrate storage bins' air emissions are controlled by Donaldson Torit fabric filter (baghouse). Appendix E contains the baghouse pressure drop readings during the test.

Northshore's No. 6 Pelletizer is a straight grate furnace manufactured by Arthur G. McKee Company. The furnace has three major operating zones referred to as the drying zone, firing zone and the cooling/recoup zone.

Unfired green balls comprised of iron concentrate and a composite binder composed of bentonite and organic binder (starch) enter the furnace at the drying zone. The green balls are then dried using heat recouped from the furnace. The air from the drying zone is referred to as 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 and oil fired burners are located in the firing zone for providing necessary heat. During the stack testing, the furnaces were fired on natural gas. 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.

The Furnace 5 hood exhaust and waste gas air streams are combined and directed to wet wall electrostatic precipitators (WWESP) for emissions control. The source gases are distributed uniformly between three WWESPs (CE266-268).

Operating parameters of the Furnace 5 Hood Exhaust/Waste Gas stack and W'WESPs were recorded every ten minutes for the duration of each test run. During the test the power grids were turned off. The taconite production rate during the testing averaged 127 long tons of fired pellets per hour (LTPH). The liquid flow rates, water flow rate, and power grid readings for all the tests are located in Appendix E.

# Sampling and AnaIri7 rrocedure

All testing was performed from ports meeting EPA Method 1 criteria (40 CFR Part 60, Appendix A). Test port locations and traverse point detail are presented in Figures 1-4. The Furnace 5 Hood Exhaust/Waste Gas Stacks are identical to each other.

Volumetric airflow determinations were performed in accordance with EPA Method 2 (40 CFR Part 60, Appendix A) using an S-type pitot and using an S-type pitot in conjunction with the Method 5 sampling train.

The molecular weight of the source gas determined by EPA Method 3/3A (40 CFR Part 60, Appendix A). An integrated bag sample was collected analyzed using an oxygen and carbon dioxide analyzer calibrated following Method 3A analyzer calibration instructions. The oxygen and carbon dioxide concentrations at all three Furnace 5 Hood Exhaust/Waste Gas Stacks are the same, so only one set of bag samples was collected during Test 2 and Test 4 (501 and 503 stack tests) because they were performed simultaneously, and the oxygen and carbon dioxide results were used for both4ests. The Concentrator Bin — Section 9 (5VO40) is a non-combustion source so ambient air conditions of 20.9% 02 and 0.03% CO2 was assumed and was verified using a Teledyne portable oxygen analyzer.

Stack gas moisture content was determined using EPA Method 4 (40 CFR Part 60, Appendix A) in conjunction with the Method 5 sampling train.

Particulate matter concentration and emission rates were determined in accordance with EPA Method 5 (40 CFR Part 60, Appendix A). Particulate concentration determinations that included condensible particulate matter were determined using EPA Method 202 (40 CFR Part 51, Appendix M). All particulate matter is assumed to be less than 10 microns for the purposes of determining PM 10 emissions,

Sulfur dioxide concentrations were determined in accordance with EPA Method 6 (40 CFR Part 60, Appendix A) in conjunction with Method 5 as discussed in section 6.1.1.

EPA Method 19 (40 CFR Part 60, Appendix A) was used to determine the particulate and sulfur dioxide emission rates using Equation 19-1 'Oxygen-Based F Factor, Dry Basis'. The F Factor of 8,710 dscf/MMBtu for natural gas from Table 19-2 was used in Equation 19-1.

## Reason the emission unit is to be tested: Satisfy the performance testing requirements under GP014 for Furnace 5 (EU634) particulate and sulfur dioxide emissions. All particulate tests will be performed using EPA Method 5 with the assumption that all filterable particulate matter is less than or equal to 10 microns (PM 10 ). All three stacks (SV266, 5V267, SV268) will be tested for filterable particulate matter emissions for demonstrating compliance with the MACT limits. One of the three stacks will also be tested for PM10 determination by using EPA Method 202 in conjunction with EPA Method 5 and one stack for sulfur dioxide (SO 2 ) determination by EPA Method 6 or 6C.

PM 10 emissions will be determined on the Furnace 5 Discharge (EU635, SV269) using EPA Method 5 and Method 202. The results Will be used to demonstrate compliance with the air emissions permit limits.

## One filterable particulate test will be performed on one of the Concentrator Bin Sections 8 or 9 (SV039 or SVO40: in GP010) for demonstrating compliance with the MACT limits.
Diagrams of the sampling locations, giving all relevant dimensions, will be provided in the test report for this project or upon request. PART II: Testing Requirements The table below gives a summary of the pollutants to be tested and test methods.

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

Test Method' Method 1 Sample and Velocity Traverses for Stationary Sources. (once at each stack vent) Method 2 Determination of Stack Gas Velocity and Volumetric Flow Rate. One determination concurrent with each Method 5 sample test run. Method 3 Determination of Oxygen and Carbon Dioxide Concentrations in Emissions from Stationary Sources. One integrated gas sample collected during each Method 5 test run at the indurating furnace stacks. The Furnace Discharge and Concentrator Bins are non-combustion sources and ambient conditions will be assumed (20.9% oxygen and 0.03% carbon dioxide). 20.9% oxygen will be verified using a portable oxygen analyzer.

Northshore Mining Company Page 3 of 5

## Test Method
. ' Method 4 Determination of Moisture Content in Stack Gases. One determination concurrent with each Method 5 test run. The moisture content of the indurating furnace stacks and the Furnace Discharge are expected to be saturated. If this is determined to be true, the moisture content of the stack gas will be limited to the saturated value of the average stack temperature recorded during the test run. Method 5 Determination of particulate matter. Three runs per test with a sampling time equal to or greater than 60 minutes per run and a sample volume greater than or equal to 32 dry standard cubic feet. For MACT testing the run times will be increased to 120 minutes or more per run. All filterable particulate matter will be assumed to be PM 10

. Method 202 Determination of condensible particulate matter. Used in the determination of PM 10

. Method 6 or 6C Determination of sulfur dioxide. Three runs of 60 minutes or more. If Method 6 is performed, it will be in conjunction with the Method 5 sampling by replacing the water in the impingers with hydrogen peroxide. The emission rate will be determined using the following equation:



## E (1b1 MMB1u) = 

## Cd ><FFactor[20 .9 1(20.9 — % 

## 02dry)] where:

Cd is the pollutant concentration in lb/scf 8710 is the F factor for natural gas (Table 19-1 CFR 40 Part 60, Appendix A) 0 2 dry is the exhaust oxygen concentration percent-dry

All test methods are found in 40 CFR Part 60 Appendix A and 40 CRF Part 60 Appendix M with modifications listed above.



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

Part VI: Other The particulate determinations will be reported in units of grains per dry standard cubic foot (gr/dscf) and pounds per hour (1b/hr) from each stack for PM, TPM and PK () where appropriate. Sulfur dioxide will be reported in ppm, lb/hr and lb/MMBtu.
