EXECUTIVE SUMMA_RY OF EMISSIONS 

On March 23 and 31, 2006, Environmental Monitoring Laboratories performed air emissions 

testing for Columbus Brick Company in Columbus, Mississippi. Testing was performed to 

determine particulate, SO2, HC1, and HF, emissions from the No. 3 Brick Kiln in accordance 

with requirements of the Mississippi Department of Environmental Quality. 

The following table is a summary of test results. 

# per hour concentration #/ton produced Allowable 

Emissions 

Particulate 0.64 0.0073 grains/dscf 0.048 0.42 #/ton 

SOa 8.17 77 ppm 0.60 500 ppm 

HC1 0.61 11 ppm 0.045 0.26 #/ton 

HF 0.61 20 ppm 0.045 0.057 #/ton 

Mr. Ed Thebaud of Columbus Brick Company coordinated the testing project. Otis Rayburn 

and Bill Norwood of Environmental Monitoring Laboratories collected samples. HC1 and HF 

samples were shipped to Oxford Laboratories Danny Russell of Environmental Monitoring 

Laboratories prepared a report of testing. 

Following is a report of the test. 
1.0 TEST RESULTS: 

The following tables are summaries, of the measured flow parameters and test results for sulfur 

dioxide emissions testing done on March 23, 2006, and particulate, HC1, and HF, emissions testing 

done on March 31, 2006, for the No. 3 Brick Kiln at Columbus Brick Company's manufacturing 

facility in Columbus, Mississippi.

2.0 SOURCE DESCRIPTION: 

The No. 3 Kiln is a typical brick tulmel kiln used to fire bricks. It operates at a 24 hour and 6 

minute cycle. There are 21 car positions in the kiln and therefore a 20.99 car per day throughput. 

Each car has 9216 bricks with a fired weight of 3.35 pounds per brick. Production rate then is 324 

tons per day or 13.5 tons per hour. Production records for the days of testing are provided in 

Appendix C. 

The No. 3 Brick Kiln exhausts to the atmosphere by way of a 43.5 inch diameter vertical stack 

extending through the roof of the building housing the kiln. Two sample ports at 90 ° 

are provided 

at a location 104 inches (2.4 diameters) below the stack exit and 354 inches (8.1diameters) above 

an inlet duct. 

3.0 TEST PROCEDURES: 

Test procedures used are those described in the Code of Federal. Regulations, Title 401 Part 60, 

Appendix A. Specifically, Methods 1 through 4 were used to determine the number of sample 

points, volumetric flowrates, and moisture content, and Method 6 was used to measure SO2 

emissions. The Method 6 option of using a Method 5 sample train for SO2 was used in order to take 

advantage of simultaneous determination with velocity and moisture. Particulate matter and HC1-HF 

emissions were measured in a single combined Method 5 and Method 26A sample train. Sample 

duration was 60 minutes for each of triplicate samples for the SO2 test and for the PM, HC1, HF test. 

HC1 and HF samples were shipped to Oxford Laboratories in Wilmington, NC for analysis. A report 

of that analysis is provided in Appendix C.
