We also asked in our original request that the Category HAPs spreadsheet be updated to includ e the

correct emissions except for POM speciated HAP emissions. How are you making out because Century

is the last company that we are waiting for and we need it by next week? Thanks. Call me if you have

any questions.

The spreadsheet that needs the data updated is the ReleasePoint spreadsheet and the KMZ file

containing the current lat/longs that need to be corrected. The password to unprotect the Excel files for

primary aluminum is "erg1984". Let me know if that doesn't work.

Rochelle

I spoke with you the other day regarding the EPA’s request to update the Primary Aluminum facility HAP

data bases.

Please let me know which files need to be updated and returned to you of the files that were sent to the

plant in the zipped directory(see below). Also, what is the password to unprotect these sheets?

Thank you
