	Notes for out May 23 telephone conversation
	
	

Dear Mr. Nugent:

Here are my notes from out May 23 conversation.  I know I didn't capture 
everything here.

On May 23, 2007, a telephone conversation took place between Mr. Keith 
Barnett of the U.S. Environmental Protection Agency and Mr. Dan Nugent of 
Buzzi Unicem USA, Inc.  The purpose of the conversation was to discuss 
several site specific issues on the sampling of kiln feed and fuel 
materials and cement kiln dust.

1.  Mr. Barnett conformed that cement kiln dust samples did not have to be 
analyzed for total organic carbon.

2.  Mr Barnett confirmed that 2006 data were sufficient ( for something 
here but I didn't record what)

3.  Facility with raw materials storage in a hall enclosure.  large 
concrete bin with bottom reclaimed to raw mill.  Only opportunity to 
sample is feed conveyer.  Mr Barnett confirmed this is acceptable.  I 
think we also discussed getting representative samples from the piles?

4.  Facility has raw materials form several suppliers.  Stockpiled in a 
storage area and stockpiles are mixed.  A mixed sample is acceptable.

5.  Facility with 4 long dry kilns.  All four get same fuel and feed.   
Dust from PM control is commingled into common duct.   One set of samples 
will be sufficient here.  

6.  If a kilns runs only 8-20 hours per day two samples a day will be 
sufficient.
