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.

RE: USS- Minnesota Ore Operations (Minntac) 

Notification of Testing and Test Plan 

Dear Andrew, 

This document is the Notification of Testing and Test Plan for performance tests to be conducted 

during the week of April J 8, 2005. Tests will be performed on the Agglomerator Line 6 and Line 

7 waste gas stacks (SV144 and SV151 respectively), and the Crusher 078-01-2501 tertiary 

crusher dust collector (SV054). 

Notification was previously given to test the Crusher dust collector, SV054. The test was to have 

been conducted during the week of February 14-18, but could not be completed because of a 

process line breakdown. An extension was granted by Andy Place of the MPCA following e-mail 

communications with Ray Potts ofMinntac.

regulation for the emission limit. 

Group 11 Agglomerator Line 6 and Line 7 --PM, PM10, Opacity, CO, S02, VOC, and 

Fluoride 

There are no permitted emissions limits for PM10 CO, VOC and Fluoride until the PSD · 

permit is in effect. The following emissions limits are in effect. 

Particulate Matter (PM) 

Opacity 

Minn. R 7011.0610 subp. l(A)(J) 

0.30 grains per dry standard cubic foot, or the less stringent of either Minn. R

Opacity 

Minn. R 7011.0610 subp. l(B) 

Less than or equal to 20% opacity . 

. (2) Description of procedure for fuel sampling and analysis, where applicable. 

Coal will be sampled during the testing and analyzed for moisture, Btu value, and sulfur 

content. 

Part 3. Operating Conditions 

(I) List the process or operating rate and conditions of the process equipment and the air 

pollution control equipment for the test. 

All tests will be performed while the associated process equipment is operating normally 

and all control equipment will be operated normally. 

Green ball feed rnte range 525 to 600 L TPH during both tests 

Fuel will be a blend of natural gas and western coal during both tests. 

The emission units associated with the SV054 collector include 4 bins that feed 8 crushers. It 

is the operator's goal to keep the bins optimized but there are situations, feed to the crushers 

may actually stop for short periods of time. For that reason we have estimated large ranges 

of operating rates for the collectors. 

(2) Explanation of why the proposed conditions are considered to be in accordance with Part 

7017.2025, Subpart 2, for required testing conditions. 

The statement about the assumption of worst case conditions in the cited subpart applies. 

(3) List the range of process or operating rates for this emission unit. 

The minimum process rate is zero. The maximum is approximately 600 long tons per 

hour of green ball feed rate. 

~ 3 -
SV054 serves the inlet to 4 surge bins that feed 8 third.stage crushers. It is anticipated that, 

during the testing, the bins will be filled at a rate of between 1600 and 4000 long tons per 

hour. 

(4) Descriptions of how air pollution control and process equipment wilt be monitored. 

The emission control units will be monitored for pressure drop and water flow during all 

tests. 

The 078-0l-25G 1 (SV054) dust collector is a wet scrubber and will be monitored for 

wa:ter flow and pressure drop during the tests. Scrubber water flow rates and pressure 

drops will be recorded at least every fifteen minutes during the testing. Process rates will 

be monitored during all three test runs for the stack. There are no weigh scales associated 

with the 078-01-25Gl (SV054). For this collector the process weight will be the average 

output from the four bins (the sum of the crushers being fed from the bins). The 

assumption is that the feed to the bins should be approximately equal to what is being 

discharged from them. 

Part 4. Test Methods 

(I) List ofthe methods to be used to determine the emission rate of each pollutant. 

Test Port Location 

·Determination of velocity and volumetric flow 

Determination of gas molecular weight 

Determination of moisture content 

Determination of PM 

Determination of Condensable PM 

Determination of CO concentration 

Determination of VOC concentration 

Determination of S02 concentration 

Determination of Fluoride concentration 

Visual Determination of the Opacity of Emissions 

EPA Method 1 

EPAMethod2 

EPA Method 3A 

EPAMethod4 

EPA MethodS 

EPA Method 202 

EPA Method I 0 

EPA Method 25A 

EPA Method 6C 

EPA Method l3B 

EPA Method 9 

Note- both filterable and condensable particulate matter will he measured. PM10 measurements 

(Method 20 lA) cannot be made at the waste gas stack because of high moisture content in the gas 

stream. PM10 will be determined by adding the inorganic condensible particulates to the dry plus 

inorganic particulates. 

(2) Numher of test runs, length of the test runs, and sampling rate for each method. 

3 one-hour test runs except for Methods I, 2 and 9 

Method 9 will be 1 one-hour observation performed in conjunction with one Method 5 

test run. 

·4-
(3) Reference to any compliance document, federal regulation, or Minnesota rule or statute 

requiring use of specific methods or procedures. 

Not applicable 

(4) Summary ofreasons for proposing to use alternative or equivalent method. 

None proposed 

(5) For test methods other than reference methods, statement of the detection limit and the 

degree· of accuracy of that method at the expected emission rate and under the conditions of 

the performance test. 

None applicable 

Test Schedule and Pretest Meeting 

The testing is scheduled to occur during the week of April 19-22, 2005. At the preference 

of the l:vfPCA, we would suggest the pretest meeting could occur no less than 7 days 

before the testing begins and be conducted via telephone.
