RE: SunCoke's review - target date

Hello,

Thank you very much for providing comments and information to EPA's responses.

One issue that EPA wanted to follow up on is regarding calculating tons per year (TPY) for the HNR charging units.

The EPA will use lb/ton wet coal charged values as the industry emission factor unit of measurement starting point for calculating TPY emissions for the units that do not have Coke ICR Enclosure 2 test data (Thank you for providing the Appendix G for confirmation of these values).

With that in mind, the EPA still needs some additional data to use in conjunction with the emission factors in order to calculate TPY emissions.

The EPA response to the SunCoke whole industry data review outlined 4 additional data needed options: 
For the new methodology, we need one of these four data options for wet coal charged values to move forward with the TPY calculation:
1) Annual wet coal charged per PCM; or
2) Annual wet coal charged per Battery; or
3) Wet coal charged capacity per PCM w/ CU%; or
4) Wet coal charged capacity per Battery w/ CU%.
Please let us know which additional data option you think is the best methodology for calculating TPY emissions for the charging units. 
Attached is the EPA response applicable to this issue for your reference with the tab `Units' for you to input the needed data for all the SunCoke facilities.

Please let us know if you have any questions or if there is something we are misunderstanding about your last response on this issue.

Thank you!
