Yellow Cells: Where there is no reported data for a coal subcategory, the baseline average for coal/stoker was used to fill the data gap. Where there is no reported data for a bagasse subcategory, the baseline averages from the same 

wet biomass subcategory were used to fill the data gaps. Where there is no reported data for a wet biomass subcategory, the baseline averages from the same dry biomass subcategory were used to fill the data gaps. Where there is no 

reported data for a dry biomass subcategory, the baseline average for dry biomass/stoker was used to fill the data gaps.

Notes:

Metals/PM Control Groups: It was assumed that all coal and biomass units had at least a cyclone 

or multiclone installed for metals and PM control. Control groups 5 and 6 for metal and PM emissions 

from solid-fuel boilers were merged together into a single control group (5).

Green cells: Whenever there is not an uncontrolled average but there is an average for another 

control group, the percent reductions were used to back-calculate an uncontrolled average. 

Additional data gaps were filled by applying percent reductions to the calculated uncontrolled average 

(see % Reductions tab). Uncontrolled baseline averages that were back-calculated and the averages 

based on those values appear as green cells.

Orange cells: Where there is no reported data for bagasse, the wet biomass baseline average from 

the same control group was used to fill the data gaps.

Yellow cells: Whenever there is an average based on reported data for the uncontrolled group (i.e., 

control group 6 for Mercury), any data gaps for that pollutant were filled using percent reductions 

applied to the uncontrolled average (see % Reductions tab). Baseline averages that were calculated 

using percent reductions based on a reported uncontrolled average appear as yellow cells.
