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 (SO2) 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 -8pounds per dry standard cubic foot, 

resulting in an emission rate of 0.0071 pounds per million British thermal units (1b/M1VIBtu). This SO 2emission 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 PMiowere 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. 

6 
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. 

7 
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 PM10emissions, 

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.

Testing Company and Contact: 

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. 

PM10emissions 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 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) 

02dry 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.

Please contact me at 651-296-7169 if you have any questions regarding this approval. 

Please be aware that enforcement action will be taken for performance test failures indicating emissions above applicable limits 

(excess actual emissions to the environment). Failures commonly result in assessment of a monetary penalty. Upon the first test 

failure, the Company should take immediate measures to minimize emissions. The measures taken should be documented, as they 

will become part of the record of corrective actions.
