Update on Portland Cement NESHAP Emissions Data
	
		
		Dear Jim:
		
		We wanted to give you an update on the Portland Cement NESHAP.  
		
		1.  Attached below is a listing for the emission factors for all 89 kilns 
in our data base.  We gave you a partial listing at a previous meeting, 
but this is all 89 kilns  rather then a subset.
		
		
		
		2.  Attached below is all the THC data we recently received.  
		
		
		
		3.  Attached below is the HCl data.  Note that HCl emissions data was 
obtained by Method 321 and Method 26.  Due to issues raised about 
inaccuracies of Method 26 for this source category, we believe the Method 
321 data are more accurate.
		
		
		  
		4.  As you correctly noted, we have collected more PM data as part of the 
NSPS review which you recently sent to Steve Silverman.  We are 
incorporating that information in the NESHAP docket. 
		
		Let me know if you have any questions.
