Annual Air Emissions Estimators
(Based on WebFIRE Emissions Factors) for some Source Classification Codes 

These emissions estimators should only be used as a last resort. The owner or operator of an air emissions unit shall use, on a pollutant-specific basis, the most accurate of the approaches set forth in rule paragraph 62-210.370(2)(a), F.A.C., to compute the emissions of a pollutant from an emissions unit.

Instructions: For a spreadsheet to automatically estimate potential or actual annual emissions (tons/year), enter the appropriate fuel/process information in the cells in the upper left-hand corner of the spreadsheet (Emissions Unit Number (EU No.) is optional).
