--------------------------------------------------------------------------------

Summary

      A Microsoft TEAMS conference call was held on August 25, 2021, between the EPA, the Coke Oven Environmental Task Force (COETF) of the American Coke and Coal Chemicals Institute (ACCCI), and coke ovens company representatives as part of the residual risk and technology review (RTR) for Pushing, Quenching, and Battery Stacks (PQBS) NESHAP (40 CFR part 63, subpart CCCCC). 
      
      Industry representatives expressed their concern with AERMOD and stated that there was a modeling code error in the buoyant line plume (BLP) model. Industry representatives said that the error would result in overstated risk values. Industry representatives requested that EPA work to prioritize the error before modeling for the PQBS industry and were concerned about public comments on the results if the error was not fixed. The EPA thanked industry for the information. The industry said they would be checking the NESHAP site for the corrected AERMOD input file.
