Air Emissions Modeling

2011 Version 6.3 Platform

The 2011v6.3 platform is based on the 2011NEI version 2 and includes projected future years of 2017, 2023, and 2028. The modeling cases 2011ek and 2017ek supported the Final Cross-State Air Pollution Rule (CSAPR) Update, a rule related to interstate transport for the 2008 Ozone National Ambient Air Quality Standards (NAAQS). Updates to the platform were made to support preliminary modeling of interstate transport for the 2015 Ozone NAAQS with cases 2011el and 2023el, and preliminary modeling for the assessment of reasonable progress for regional haze with cases 2011el and 2028el. The inventories were further updated based on public comments for an updated analysis of interstate transport for the 2008 Ozone NAAQS with cases 2011en and 2023en.
