Evaluating Ozone Control Programs in the Eastern United States (1997-2004): State and Local Information

EPA and state and local agencies have worked diligently to limit ozone formation by reducing emissions of its key precursor gases: nitrogen oxides (NOx) and volatile organic compounds (VOCs). Emissions and ozone trends reflect implementation of these programs. In the eastern United States, emissions of NOx and VOCs have decreased by 25 and 21 percent, respectively, from 1997 to 2004. In response, ozone has declined by 14 percent, on average.
