Lynn@ epa. gov' Cc: Reeves, David Subject: Revised Mag Tape Inputs Here are the revised inputs for the Magnetic Tape risk test. ( You should alread y have the supporting data, including contact reports, memos, and process diagra ms, which I provided at the last meeting.)

I have broken down the emissions for each facility by emission point using facil ity reported information, where available. I have also included NEI data in a c ouple of cases: ( 1) For Quantegy, I filled in a few gaps with NEI data. ( I also eliminated the fugitive emission point at Quantegy which emits styrene. Our contact at Quanteg y says this process, which was a plastic injection molding process, has shut dow n.) ( 2) For Imation, it was possible to segregate the magnetic tape emission points in the NEI from the rest of the facility based on SIC code 3695. Since the emis sion estimates in the NEI are comparable to what we have from the TRI, and they are more specific to the magnetic tape process, I substituted the NEI data for a ll of the TRI data previously submitted.

For Sony, I included two sets of emission data: ( 1) One set of data is based just on the TRI ( same data as submitted before). ( 2) The other set of data uses data from the Alabama DEM for cobalt and data fro m the TRI for everything else.

For the rest of the facilities ( JVC, Kodak, and 3M), I used the same data as bef ore.

Let me know if you have any questions.
