Wednesday, (May 8, 2019)

Training Session #1 - Prognostic Meteorology
(Acquiring, evaluating, and preparing prognostic meteorological data for use in dispersion models)

Chris Misenis, EPA-OAQPS

Training Session #2 - AERSURFACE
(This session will look at the changes in the land cover classifications since the 1992 NLCD, the challenges these changes present in assigning surface characteristic values, and features in the new draft version of AERSURFACE to address these challenges.)

Clint Tillerson, EPA-OAQPS
Training Session #3 - Secondary PM2.5 MERPs Demonstrations
(A step by step demonstration of how to apply Tier 1 MERPs to assess secondary PM2.5 impacts in PSD permits, including a refined analysis to address long-range transport into Class I areas)
Michael Moeller, EPA-Region 4

Training Session #4 - MCH Lean Implementation
(From the Big Call to SOPs & checklist, this training session will present the steps that the Agency is implementing to fulfill the MCH Lean project and the draft material that will be added to the
MCH Operational Plan for the co-regulating agencies to follow.)
