This TSD describes how the emission inventories were prepared for air quality modeling by the U.S. Environmental Protection Agency (EPA) for air toxics and criteria air pollutants that represents the year 2015 based on the 2014 National Emissions Inventory (NEI), version 2 (2014NEIv2). This document focuses on the emissions modeling component of the 2015 modeling platform, which includes the emission inventories, the ancillary data files, and the approaches used to transform inventories for use in air quality modeling. Many emissions inventory components of this air quality modeling platform are based on the 2014NEIv2, including projections to year 2015 for some emissions sectors.You may need a PDF reader to view some of the files on this page. See EPA’s About PDF page to learn more.
