Where is ozone a problem?
[Back to Top] Ground-level ozone is a problem anywhere it exists. Typically, it is produced in urban areas where there are lots of cars, industry, and other sources of combustion. Ozone can travel with the wind to other places and become a problem there, too. In North Carolina, our greatest areas of concern are the greater Charlotte area, the Triad (Greensboro, Winston-Salem, and High Point), and the Triangle (Raleigh, Durham, and Chapel Hill). Each of these areas has had a violation of the federally enforced one-hour ozone standard in previous years. Future growth projections in population and vehicle use indicate that these areas along with other communities of North Carolina could potentially violate the proposed eight-hour federal standard.
