Permitting: Emission Calculation Sheets


The following emission calculation sheets are provided to help small businesses estimate their emissions. The emission factors used are from EPA's AP-42 Compilation of Air Pollutant Emission Factors. If you have manufacturers or industry emission factors you may use them, just include the reference from which the factor originated. The sheets are in Adobe Acrobat (PDF) file for a manual calculation and Microsoft Excel (XLS) for a computer calculation.

Note: These tables are under construction, so come back in the future to see what has been added and how many NAs (not available) have been updated to a usable document.
