RE: Coke - EPA responses to Model Shell File Review and emissions files


Gabrielle,
 
Per your question regarding the Process ID/Emission Unit Description, below is our response:
 
Our comments on doors simply referred to the terminology used in the spreadsheet.  The spreadsheet referred to doors as "coal side" and "coke side."  For the coke byproducts recovery industry, coal charging is conducted through open lids on charging ports on top of the battery and not through doors on the battery sides, as is the case for the nonrecovery coke industry.  The correct terminology for byproducts industry doors is "push side" and "coke side."  The push side is the side of the battery where the pusher machine ram contacts the coke and pushes the coke out of the oven.  The coke side is the side where the coke exits the oven.  We wanted to make this clarification because, for emissions calculating purposes, byproducts recovery battery "coal side" and "coke side" doors are treated the same, while for nonrecovery batteries they are not.
 
I hope this clarifies any questions you may have.  Feel free to contact us with any other questions.
 
Best regards,
 
Allen C. Dittenhoefer, Ph.D.

Subject: RE: Coke - EPA responses to Model Shell File Review and emissions files
 
Hello,
 
Thank you very much for your review on the modeling and emissions files.
Below are the EPA responses and revised files attached. 
 
1) Coke_2017-EIS-NEI_Noncategory-Other-Units_01282021_COETF Rev(2) 02-12-21.xlsx
COETF Comment: Per Al Dittenhoefer's e-mail earlier this afternoon, we've noted where some sources/emissions are already accounted for in the byproducts plant emissions.  
EPA Response:
ABC Coke, will delete rows from NONCATEGORY file.
Bluestone, will delete rows from NONCATEGORY file. 
USS Clairton, will delete rows from NONCATEGORY file.
COETF Comment: We had one additional comment concerning emergency engines with highly intermittent emissions.
Emissions for Bluestone Coke in rows 760-769 are for diesel-powered emergency generators and are highly intermittent sources.  If these sources will be modeled, what release parameters will be used as they are all missing?
EPA Response:
Will delete rows from the NONCATEGORY file due to intermittent operation.
 
Revised file attached:
Coke_2017-EIS-NEI_Noncategory-Other-Units_02162021.xlsx
2) CokeOven_RTR_ModFile_COETFResp_122420_EPAResp_010521_COETFResp012221_EPAresp_01282021_COETF_021221.xlsx
COETF Comment:
a. Provided responses in EPA 01-28-21 tab regarding Warren scrubber car and noted in Cell I135 that several boilers were incorrectly placed in the category tab.
EPA Response:
Will move all boilers to noncategory file.
 
b. Revised stack parameters for the Warren scrubber car in Row 84 of the category tab based on updated information from the facility.
EPA Response:
Thank you for the parameter revisions:
STACK_[or FUGITIVE] HEIGHT (ft): 22.6667 --> EPA is using the Battery height of 49.02 ft for fugitive two-dimensional sources (Release Point Type = 9). 
 
STACK_DIAMETER (ft): 6.4585 --> EPA is already using 6.4585 ft for FUGITIVE_WIDTH_SIGMAY_FT provided by COETF on 12/24/20.
 
EXIT_GAS_TEMPERATURE (F): 334.483 --> EPA will use COETF revised value. 
 
EXIT_GAS_VELOCITY (ft/sec): 45.35 --> EPA will use COETF revised value.
 
c. Added scrubber car F' calculation to Tab 18.
EPA Response: Thank you for the additional Fprime data, will send to EPA modelers.
 
Revised file attached:
CokeOven_RTR_ModFile_COETF021221_EPAresp02162021.xlsx
3) CokeOven_Category&NonCategory_RTR_ModFile_20210128_COETF_021021.xlsx
COETF Comment:
a. Revised stack parameters for the Warren scrubber car in Row 64 of the category tab based on updated information from the facility.
EPA Response:
See EPA response for 2)b. above.
b. Noted where boilers on the category tab should be moved to the non-category tab in Column A of the category tab.
EPA Response:
Will move all boilers to noncategory file.
c. Noted where the Process ID/Emission Unit Description is incorrect for EP-11 Doors as the descriptions do not apply to byproducts plants in Column B of the non-category tab.
EPA Response:
Can COETF provide more information about what the EPA needs to correct specifically for the Process ID/Emission Unit Description? 
Attached is an excel file with only the EP-11 door sources with columns for Industry Comments. 
Coke_EP-11_Doors.xlsx
COETF Comment: We have no comments on the Coke_IIS_Modeling_Emissions.xlsx file.
EPA Response: Thank you for your final review.
 
 
Thank you again for all your help!
