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 will be used in lieu of 

isokinetic testing for Method 26A as there are no entrained water droplets in the flue gas stream. Sampling will be 

conducted at a constant sampling rate of 0.75 cfm.
