Air pollution affects all Missourians as well as our economy. As we continue to work to lower Missouri’s air emissions, it is important to know that even levels of air pollution below the federal and state standards can affect your health. Small sources of air pollution near our homes and neighborhoods can collectively have a huge impact on air quality. You can take simple, everyday steps while at home or traveling on the road to protect air quality and save money while doing it. You also can make your voice heard by attending public meetings and hearings, and commenting on public notices. Be air aware to protect your health and help improve our air quality. We invite you to help us make a difference and improve air quality.
