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.

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

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 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. The 95 percent

confidence interval (alpha 0.05) was calculated as shown in Table 1.

Process data is summarized in Table 2 and detailed data provided in Appendix F.

Table 3 is a summary of total NOx emissions from the furnace by data point and a statistical

summary. The average NOx emission rate for the 157 data points was 994 Ibs/hr which is below the

permit limit of 1088 Ibs/hr.

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.

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 ofthe 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 NOx averages between

calibration times.
