Coke Boiler Emission Calculations

Hello David,

Thank you for providing the new methodology for calculating emissions for boilers.

Please see attached and review the 'EP-4 BP Boiler Stacks' tab for an example calculation of Antimony emissions using the new methodology.

Please note, if the Boiler is not regulated under 40 CFR 63, Subpart DDDDD and was operating in 2019, it will be modeled in the CCCCC category file. If the Boiler is regulated under 40 CFR 63, Subpart DDDDD and was operating in 2019, it will be modeled in the Noncategory file. 
Please review columns Q and R in the 'EP-4 BP Boiler Stacks' tab.

For Plant A Boilers 1-4 and Plant H Boiler 8, no COETF data was provided. 
If these boilers were operating in 2019 and you have data, please fill in with your data in `EP-4 BP Boiler Stacks' tab. 
There is 2017 NEI data available to use for these boilers, if necessary. See the 'Plant A Boilers 1-4 2017 NEI' and 'Plant H Boiler 8 2017 NEI' tabs.

Please let us know if you have any questions.

If at all possible please have your review done before December 25, 2020.

Thank you,
Gabrielle
