Subject: Re: SunCoke's review - target date

I forgot to mention that we are looking for all industry comments to be returned to EPA by 12/24 so we can work on the revisions between holiday breaks (when its quiet around EPA). 

The items we need from SunCoke are listed below:

Whole Industry EF and ICR Data:
 Control efficiency from the pushing multiclone; We have not tested the efficiency of the multiclones, however, from our permit application for Middletown, the estimated particulate control efficiency is 98% (based on AP-42 factors).
 How to calculate lb/ton coal charged for charging units; Our ICR stack test report already calculated emission factors on a lb/ton of coal charged. See attached portion of the ICR test report Appendix G (PCM test results start on page 87).
 Confirm lb/ton coke produced is okay for pushing units.  Yes, lb/ton coke produced is appropriate for the pushing units.

Will send the following separately - 
·  Modeling Shell:
 Review and respond to EPA's responses.
Other Emissions Files:
 Review and respond.
Thanks!

Thanks Donna Lee. We will let you know if we have any follow-up comments.
 
Hope you have a nice holiday as well!

Subject: 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.
