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 Stack gas is moisture saturated, so impingers were not weighed for moisture. Header Data Vlc box milliliter H20 captured was calculated to match saturation moisture percentage. U3 Stack
