All,
 
All,
 
I have attached a link to the Model Clearinghouse reviews and approvals for the BLP/AERMOD Hybrid Alternative modeling studies conducted for the USS Clairton Plant, which we referenced in our document "Derivation of Coke Battery Buoyancy Parameters for Application to the Pushing, Quenching, and Battery Stack Risk and Technology Review."

Dr. Jones,
 
In preparation for our call on Monday, December 21, 2020, attached please find:
 The spreadsheet detailing our coke battery buoyancy parameter calculations;
 A document entitled "Derivation of Coke Battery Buoyancy Parameters for Application to the Pushing, Quenching, and Battery Stack Risk and Technology Review"; and
 Two referenced documents of studies of vertical velocity/temperature measurements at coke batteries used in the buoyancy parameter calculations.
 
Please note that the spreadsheet is the same as that provided in the COETF's September 29, 2020 and October 22, 2020 submissions to EPA, and the document/attachments are the same as those I sent to EPA on November 30, 2020 .
 
We look forward to our call on Monday.
