  "definition": "1. All of the data within the EIS data store at a particular point in time. It includes data submitted by S/L/T Agencies, datasets created by EIAG, and datasets obtained from other Agency sources.\n\n2. EPA prepares a national database of air emissions information with input from numerous state and local air agencies, from tribes, and from industry. This database contains information on stationary and mobile sources that emit criteria air pollutants and their precursors, as well as hazardous air pollutants. The database includes estimates of annual emissions, by source, of air pollutants in each area of the country, on an annual basis. The National Emissions Inventory includes emission estimates for all 50 states, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands.\n\n3. A national database of air emissions data. EPA prepares NEI with input from many state and local air agencies, from tribes, and from industry. This database contains information on stationary and mobile sources that emit criteria air pollutants and their precursors, as well as hazardous air pollutants. NEI includes estimates of annual emissions, by source, of air pollutants in each area of the country. NEI includes emission estimates for all 50 states, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands.\n\n4. A Clean Air Act (CAA) collection of point, area, mobile and biogenic emissions data periodically submitted to EPA's Office of Air and Radiation by State and local air programs. These data are used for air dispersion modeling, regional strategy development, regulation-setting, air toxics risk assessment, and tracking trends in emissions over time.",
