hi Phyllis, 

This is the email I sent to Hitachi:

Subject: RE: CX catalyst question

hi Tony,

Here is some general information about the facility. Please let me know if there is additional information I 

need to provide to you in order to put together a budget quote and % NOx control and % SO2 to SO3 

conversion guarantees. 

As I mentioned when we spoke last Wednesday, we have not made any decisions for our regulatory 

action, therefore, we prefer to keep the facility anonymous and prefer you contact us rather than the 

facility regarding any questions you may have. 

Please also let me know if you will claim as confidential the information you already provided on CX and 

TRAC catalyst costs as well as future information on costs and guarantees for SCR systems .

Rick, my calendar is pretty open for the week of April 5 for a brief meeting. Mid-afternoon generally works 

best for me.

Thanks so much for your help!! 

- Anita
