### Rochelle,

Yes, in 2012 we permitted the new #31 Furnace which rendered #14 Melter inactive. The new

dioxin/furan emission factor from #31 Furnace (M0031) should be used for the following representative

sources: M001A, M001B, M003C, M024D, M024F and M0031. Thanks.

### Thanks for the update. Has a request been submitted to your permitting

authority to render #14 Melter as inactive? Otherwise, we will have to count those

originally reported emissions.

### Rochelle,

You are correct, the summary we sent only had the test results for one furnace, M0031 (31

furnace.) Here’s why:

On March 29 th 

### , 2012 the Massena West Casthouse sustained a major roof fire which completely

shut down the entire Casthouse facility and took out all SMACT sources within it. Since then

we have restarted the following sources: M0034 (#35 Melter/Holder), M0035 (#36

Melter/Holder), M024D (#33 Melter/Holder) & M024F (#32 Melter/Holder). In addition, we

have permanently shut down M003A (#14 Melter/Holder) and have added a new source, M0031

(#31 Melter/Holder) . All other sources have not restarted and ther e are no foreseeable future

plans to do so.

We tested M0031 for two purposes. First it was a new source and we had to test it to show

initial compliance. Secondly, since it was nearly an identical furnace to M024F and M024D, it

was considered a repres entative source and thus the emission factors from the test will be

applied to all other representative sources.

I have highlighted the changes in the attached excel spreadsheet tab

“Modeling_File_Calc_Inputs” and revised table 38a. in tab “2011_Massena West_ICR_response”

to reflect the changes.

Please let me know if you have any other questions. Thank you.

### The summary that you sent me only had the test results for one

furnace. Did you test the other equipment emitting dioxins and

furans? Can you also review the attached information for

accuracy? Thanks
