Supporting Documentation for Coke Battery Buoyancy Parameters and BLP Plume Heights


Dr. Jones,
 
As a follow-up to my email of August 31, 2020, attached please find a spreadsheet that presents the data and supporting calculations of the BLP Buoyancy Parameter (F') values, as well as the corresponding BLP-predicted median battery plume heights.  The F' calculations were conducted in accordance with the methodology described in our document "ENCLOSURE - COETF RESPONSE TO EPA 082420.pdf" that David Ailor sent you on August 24, 2020.  This spreadsheet includes all battery dimensions (including battery heights) and temperature/vertical velocity measurements that formed the basis for these calculations.  The median plume heights were generated using the EPA BLP model and 2019 HEM4 meteorological data.
 
Please let me and Jeff Knight know if EPA has any questions regarding this submission.  Thank you.
