Executive summary 

Barr Engineering Company performed particulate matter emissions tests on seven emission sources, 

the Primary Crusher scrubber (SV001), Primary Crusher Ore Handling baghouse (SV002), Fine Ore 

Crusher scrubber (SV008), Fine Ore Drop baghouse (SV009), Machine Discharge scrubber (SV018), 

Hearth Layer Bin scrubber (SV019), and P-3 baghouse (SV022) at the ArcelorMittal Minorca Mine 

Inc. located in Virginia, Minnesota. The tests were performed to demonstrate compliance with the 

facility’s Air Emission Permit and the Taconite MACT. Control device parametric resets were not 

performed during this series of tests. Results of the tests are presented in the summary table below.

Stack testing procedures and methods 

Testing was performed from ports meeting EPA Method 1 criteria. The Method 1 criteria are listed in 

the table below for each source. Sample port location and traverse point detail are provided in

Volumetric airflow determinations were performed in accordance with EPA Method 2 using an Stype pitot tube. Airflows were determined in conjunction with the Method 5 tests. 

Stack gas compositions used to determine gas molecular weight were at ambient concentrations. 

Stack gas moisture content was determined by the performance of Method 4 in conjunction with the 

Method 5 performance tests. 

Filterable particulate concentrations and emissions rates were determined in accordance with Method 

5. Condensible particulate matter concentrations collected in the back half of the sample train were 

determined using the pre-January 1, 2011 Method 202 except that hexane was used as the wet catch 

rinse in place of methylene chloride. 

Visible emissions tests were conducted following EPA Method 9. Copies of field data sheets are 

located in Appendix B. The observer certification for EPA Method 9 is located in Appendix E. 

The EPA test methods referenced above are found in 40 CFR part 60, Appendix A, except for 

Method 202, which is found in 40 CFR Part 51, Appendix M prior to January 1, 2011.
