2014 National Emissions Inventory (NEI) Documentation
The NEI database includes air emissions sources of both criteria of both criteria and hazardous air polluntants. Data are available for many facilities and as county totals. The 2014 NEI is the next inventory on the three-year cycle and the EPA will create it using data provided by State, Local and Tribal air agencies. The Emissions Inventory System (EIS) helps the EPA to build the NEI.
