Yes, we have comments and requests for more information that I will send you later today. We just developed a final draft to our response letter yesterday so this is timely question.

Dr. Jones and team,
 
We are checking in to see if you have been able to review the supporting information for the F' values and BLP plume heights submitted by the COETF.  Please let us know if EPA plans to use these values in the RTR modeling or, if EPA has any other questions or needs additional information, we can arrange a call to discuss as soon as possible and before the end of the month.

Subject: Technical Documentation on Buoyancy Parameters and BLp Plume Heights 
 
Dr. Jones and team,
 
Attached for your review is a document entitled "Derivation of Coke Battery Buoyancy Parameters for Application to the Pushing, Quenching, and Battery Stack Risk and Technology Review."  This document provides the additional background and technical support that EPA requested relating to the buoyancy parameter (F') and BLP plume height information that the COETF provided via email on September 29 and October 22, 2020.  I have also attached copies of two technical documents that describe the coke battery vertical velocity and temperature data used to derive F' values. 
 
Please let me and Jeff Knight know if EPA has any questions regarding this submission.
