Subject: 
Review of Whole Industry Test Data, Coke Byproduct Chemical Plant Emissions, and Revised Clairton Byproducts Spreadsheet

Hello Gabrielle,
 
Attached please find our comments on the latest Whole Industry Test Data and Coke Byproduct Chemical Plant spreadsheets, as well as a revised Byproducts spreadsheet for Clairton.
 
In the Whole Industry Test Data spreadsheet, we discovered that EPA apparently misinterpreted our Aug-Sept 2020 comments on the Erie Coke pushing test data and made push sample time adjustments to all of the pollutants, instead of just the dioxins and furans.  It is our understanding that the lb/hr emission rates in the Erie Coke pushing test report already accounted for pushing sampling time.  It was just the dioxins and furans emission rates that we believe EPA needed to correct in the August 2020 version of the spreadsheet.  
 
For the Coke Byproducts Chemical Plant spreadsheet, we noted that we failed to include emissions from the Clairton aeration basin and byproducts pitch traps, which we have added.  Accordingly, we are including the revised stand-alone Clairton byproducts emissions spreadsheet that lists these emissions.  Please note that we have included these revised Clairton emissions in the "Clairton" tab of the industry byproducts spreadsheet.  The addition of these Clairton byproducts emissions was noted in the Coke 2017 EIS-NEI noncategory-other-units spreadsheet that Mary Kaplan is sending today, and we wanted to alert EPA of any inadvertent "double-counting" of these emissions.  We apologize for any inconvenience this has caused.
 
We have no comments on the Method 303, fugitive pushing, boilers, and flare emissions spreadsheets.
