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.

CTM-033 was modified to use three impingers with 2 Normal NaOH solution and a 60 minute run time, as described 

in the attached ICR TEST FAQ 025. The first impinger pH was checked at each port change and replaced with a 

fresh impinger when the pH was less than 12.

Hydrogen Fluoride Method 26A 3 180 0 The stack gas is 

saturated with 

moisture, so the 

impingers were not
