The main goal of the Baton Rouge 8-Hour Ozone Attainment Demonstration Study is to develop the photochemical modeling data bases and associated analysis tools needed to reliably simulate the processes responsible for 8-hour ozone exceedances in the Baton Rouge region and the evaluation of realistic emissions reduction strategies for inclusion in the Baton Rouge 8-hour ozone SIP.

 

Based on measured ozone data from 2001-2003, the EPA designated the Baton Rouge 5-Parish area as a Marginal 8-hour ozone non-attainment area. Although EPA does not require a modeled attainment demonstration for Marginal non-attainment areas, the Baton Rouge area has experienced high ozone conditions in 2005 and to date in 2006 and will not attain the 8-hour ozone standard in 2006 to meet the June 15, 2007 attainment date for Marginal areas.
