Saturday, January 01, 2011 - The Southwest Clean Air Agency now has an interactive combustion monitoring worksheet available as a Microsoft Excel file. This new worksheet will help facilities correctly report emissions after testing their combustion devices. SWCAA also has an example of this worksheet filled out and available as a PDF. These documents are located on our Forms page under Miscellaneous. SWCAA encourages facilities to use this worksheet in place of the form included with the permit because it interactively corrects the test results for drift, span gas and oxygen level, thus eliminating the need for a manual calculation. The form also has a few built in warning messages to alert the user to common problems that can result in the emission tune up not providing valid results. Please use this new worksheet and provide us with feedback. If you have questions about how to use this worksheet, call us at 360-574-3058.
