What:    Independent Workshop on Ozone NAAQS Science and Policy
When:   April 7-9, 2015
Where: The University of Texas at Austin


Texas Commission on Environmental Quality (TCEQ) held an Independent Workshop on Ozone NAAQS Science and Policy April 7-9, 2015. The U.S. Environmental Protection Agency (EPA) is proposing to lower the National Ambient Air Quality Standard (NAAQS) for ozone from the current level of 75 ppb to a level within a range from 65 to 70 ppb. This public workshop was designed to provide an independent evaluation and synthesis of key considerations for approaching the difficult ozone NAAQS decision. A diverse group of well known and respected science and policy experts engaged in robust discussions on key issues, so that TCEQ and others could gain a better understanding of the issues and implications.
