Emissions Modeling Technical Support Document: Tier 3 Motor Vehicle Emission and Fuel Standards

The U.S. Environmental Protection Agency (EPA) developed a year 2007 air quality modeling platform in support of the Tier 3 Motor Vehicle Emission and Fuel Standards. The air quality modeling platform consists of all of the emissions inventories, ancillary files needed for emissions modeling, and the meteorological, initial condition, and boundary condition files needed to run the air quality model. This platform uses all Criteria Air Pollutants (CAPs) and a select set of Hazardous Air Pollutants (HAPs). This document focuses on the emissions modeling components of the 2007 platform, including the emission inventories and the ancillary data and the approaches used to transform emission inventories for use in air quality modeling. This document contains five sections. Section 2 describes the inventories input to Sparse Matrix Operator Kernel Emissions (SMOKE) for the 2007 base case. Section 3 describes the emissions modeling and the ancillary files used to process the emission inventories into a form that can be used by the air quality model. Section 4 describes the development of the 2018 and 2030 Tier 3 FRM reference and control case inventories (projected from 2007). Data summaries comparing the 2007 base case and the 2018 and 2030 reference and control cases are provided in Section 5. Section 6 provides references.
