The Emissions Modeling System for Hazardous Air Pollutants (EMS-HAP) is a series of computer programs that process emission inventory data for subsequent air quality modeling. EMS-HAP accomplishes two goals: (1) It processes an emission inventory, such as the 1996 National Toxics Inventory, for use in the Assessment System for Population Exposure Nationwide (ASPEN) dispersion model. (2) It allows you to estimate future-year emissions data for use in the ASPEN dispersion model. To accomplish the first goal, EMS-HAP: quality assures point source inventory location and stack parameter data and defaults missing or erroneous data where possible, groups and/or partitions individual pollutant species (e.g., groups lead oxide, lead nitrate into a lead groups; partitions lead chromate into lead and chromium groups), facilitates the selection of pollutants and pollutant groups for modeling, spatially locates county-level area and mobile source emissions to the census tract level using spatial surrogates such as population, allocates county-level aircraft emissions to airport locations, temporally allocates annual emission rates to annually averaged (i.e., same rate for every day of the year) 3-hour emission rates based on the type of source, and, produces emission files formatted for direct input into the ASPEN model.
