Hi Cortney,
Attached are EPA's responses to the initial set of interagency comments.
We'll be sending responses to the second set of comments separately.  As we 
were working to address the comments, some questions arose regarding the HAP 
emission factors developed by our contractors.  Therefore, we determined that 
it would be more appropriate to use the HAP emission factors from AP-42, which 
is the approach that SBA recommended we use.
We have revised the emission reduction and cost per ton estimates to use the 
AP-42 emission factors for HAP.  The estimates for VOC also change since the 
VOC emissions are a function of the HAP emissions.  The revised estimates are 
attached.
(See attached file: Existing SI RICE NESHAP cost per ton and emission 
reduction estimates 8-2-10.xls)(See attached file: Interagency comments on 
RICE - EPA responses 8-2-10.doc)
