SUMMARY

      A TEAMS conference was held on December 21, 2020, between the EPA and the Coke Oven Environmental Task Force (COETF), to discuss coke battery modeling, as part of the Pushing, Quenching, and Battery Stacks (PQBS) Residual Risk and Technology Review (RTR) for 40 CFR part 63, subpart CCCCC. The conference call was a follow-up to industry review of the coke modeling file "shell" data submitted to the EPA in response to EPA's information collection request (ICR). The COETF is made up of coke company representatives, their attorney, technical support, and director.
      
      Industry had previously submitted information on F' values and buoyant line plume (BLP) heights on November 30, 2020 (Attachment 1). The EPA reviewed and provided questions and responses on December 11, 2020 (Attachment 2). Industry provided additional background and technical documentation regarding buoyancy parameters on December 18, 2020, and a link to decision made by Region III concerning U.S. Steel Clairton, PA, coke modeling (Attachment 3). The EPA and industry discussed their previously submitted documentation regarding buoyancy line and point source modeling in light of the EPA questions.
