Dear Hector:

I did get the additional data.

Also, in the original 114 submittal the Mason City Kilns are listed as kilns 2

and 3, but in the newer submittal then are listed as kilns 1 and 2. Is kiln 2

now 1 and kiln 3 now 2?

(See attached file: ALL THC Daily 30

This is all the other data

remember that Holcim Kilns not in the top 5 only included emissions when the

kilns was at or greater than 70% production (CSI protocol for report to parent

company) holcim kiln within the top 5 (i.e., trident and Mason City) have already been

updated to include all emissions when the kiln was in operation if you have any

questions please call or email me

thanks
