The following describes any modifications and/or deviations to the applicable test 

methods. If alternative methods were requested, see the attachments for documentation 

of request AND approval, including dates.

Per discussion with Peter Westlin from the EPA on January 22, 2010, a three point traverse was used for Method 

26A in lieu of isokinetic testing as the unit did not have any entrained water droplets in the flue gas stream. A 

constant sampling rate of 0.75 cfm was used for this testing.
