Total Facility Approach For Setting MACT Floors 

August 6, 2010 
As part of an evaluation of MACT floors using a total facility approach (as opposed to a 

pollutant-by-pollutant approach), kilns were identified for which we had emissions data for 

mercury, THC, HCl and PM. Attachment 1 presents all of the kilns for which we have emissions 

data. For most kilns, emissions data were not available for all four pollutants. Five kilns for 

which we had data on all pollutants were identified and their emissions are summarized in Table 

1. For each pollutant we ranked each kiln from lowest emissions to highest. The lowest emitter 

for a pollutant received a rank of 1 and the highest a rank of 5. We did this for each pollutant and 

then summed the rankings for each kiln. The rankings ranged from 10 to 16. These are also 

presented in Table 2. For the best 3 performing kilns, kilns 2, 3, and 4, we calculated the MACT 

floor using the 99th confidence upper prediction limit (UPL) for mercury and PM emissions. For 

THC where we had between 2 and 3 years of daily recordings, we calculated the 99th percentile. 

The data used in the calculation are in attachments 2 - 4. Table 2 summarizes the results of the 

MACT floor analyses using a total facility approach.
