RE: SunCoke - pushing - lb/ton coke - confirmation

Hi Gabrielle,

We are fine with using the Erie coke factors, as the wet coal to coke ratio should be similar between byproduct and non-recovery plants despite differences in overall operation.
Thanks,

Kris

PS  -  I'm finishing up the capacity utilization factors for the charging emissions calculations.

Hello,

Thank you for your response regarding the emission factor units of measurement for pushing units:
Whole Industry EF and ICR Data:
 Confirm lb/ton coke produced is okay for pushing units.  Yes, lb/ton coke produced is appropriate for the pushing units.
EPA just wanted to clarify and confirm if you were okay with how those lb/ton coke values were calculated.
Apologies for the additional email in your inbox!

Currently, EPA is using the SunCoke stack test reported values of lb/ton wet coal charged and converting to lb/ton coke using the "Erie Wet Coal Charged Capacity/Coke Produced Capacity" value of 1.27.
Did SunCoke have a wet coal to coke ratio value you want to use instead of the Erie Coke value of 1.27 that is currently being used in EPA's methodology? 
If so, please provide or confirm the Erie coke value is okay to use.
Thank you again for all your help.
Gabrielle
