EPA responses to SunCoke's review of coke modeling file shell

 Hello Kris and Katie,
 
Thank you again for your review of the coke modeling file shell. Please see attached for EPA Responses to SunCoke's review of the coke modeling file shell. CokeOven_CategoryNonCategory_RTR_ModFile_20201015-Suncoke_comments_EPA-responses-11-23-20.xlsx.  Column F in this file has the EPA responses. Please provide any follow-up industry responses in Column E and also let us know if we have missed anything that already has been revised.
 
Color Key:
EPA concurs and will update
EPA has followup questions/does not concur
 
We noticed that SunCoke made revisions/comments to the model file shell in the following two main categories: 
-Changing pushing&charging units from mobile line sources to point sources.
-Combining pushing&charging units that serve multiple batteries. 
 
For EP-9 HNR Pushing (CD) line source units, the release point width will be the width of the stack. For fugitive pushing emissions, the source width will be the default width of 0.9 m (to represent edge of the battery where the escaping emissions would come from). For EP-8 HNR Charging (CD) line source units, the width will be the physical battery width. 

This is the same protocol used for all mobile units and pushing fugitives in the by-product industry.

We hope you both have a good holiday, as best as possible under these unique circumstances.
 
Regards,
Donna Lee Jones, Ph.D.
