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 29th, 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 there 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 representative 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_MassenaWest_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
