The SESARM Regional Haze Project was directed by Visibility Improvement State and Tribal Association of the Southeast (VISTAS). This project included technical analyses to meet the requirements of the Regional Haze Rule (RHR). As part of this project, VISTAS collected available visibility monitoring data, prepared emissions inventories, and performed regional modeling. The results of the SESARM Regional Haze Project analyses are archived on this web page. An effort has been made to include all pertinent summary files and final data sets that were used by SESARM and VISTAS states in RHR SIPs. Contact information is provided for individuals and agencies which are in possession of more detailed data archives.

The SESARM Fine Particle/Ozone Project was directed by the Association for Southeastern Integrated Planning (ASIP). This project included technical analyses to demonstrate attainment of the annual PM2.5 and 8-hour ozone National Ambient Air Quality Standards (NAAQS). As part of this project, ASIP gathered available data at Federal Reference Method (FRM) and Speciated Trends Network (now called Chemical Speciation Network, CSN) sites, prepared emissions inventories, and performed regional modeling. The results of the ASIP analyses related to PM2.5 and ozone attainment are archived on this web page. Contact information is provided for individuals and agencies which are in possession of more detailed data archives.
