has data used in 2346132 2008 National Emissions Inventory: Review, analysis and highlights
The National Emissions Inventory (NEI) is a comprehensive and detailed estimate of air emissions of both Criteria and Hazardous air pollutants from all air emissions sources. The NEI is prepared every three years by the USEPA based primarily upon emission estimates and emission model inputs provided by State, Local, and Tribal air agencies for sources in their jurisdictions, and supplemented by data developed by the USEPA. The 2008 NEI was built from emissions data in the Emissions Inventory System (EIS).

The data presented below are for the 2008 NEI version 3. For a detailed list of caveats and changes from version 2, and older versions, please see the Version 3 issues file.
