MEMORANDUM TO THE DOCKET:  Air Quality Modeling Technical Support Document for the Determination Regarding Good Neighbor Obligations for the 2008 Ozone National Ambient Air Quality Standard
      
      For the final Determination Regarding Good Neighbor Obligations for the 2008 Ozone National Ambient Air Quality Standard, EPA relied upon the air quality modeling performed for the proposal. This modeling is described in the Air Quality Modeling Technical Support Document (AQM TSD) prepared for the proposal (docket ID# EPA-HQ-OAR-2018-0225-0040). Since no changes were made to the air quality modeling for the final rule EPA has not updated the AQM TSD for the final rule.
