## Total Facility Approach For Setting MACT Floors

August 6, 2010

## As part of an evaluation of MACT floors usi ng a total facility appr oach (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 av ailable for all four pollutants. Five kilns for which we had data on all pollutants were identifie d 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 99 th 

## confidence upper predicti on limit (UPL) for mercury and PM emissions. For THC where we had between 2 and 3 years of daily recordings, we calculated the 99 th 

## percentile. The data used in the calculation are in attachme nts 2 - 4. Table 2 summarizes the results of the MACT floor analyses using a total facility approach.
