A non-attainment area is an area that has air quality worse than the National Ambient Air Quality Standards as defined in the Clean Air Act Amendments of 1970. It means that an area must clean up emissions to attain the official, health-based limits for that pollutant. These areas exist all over the United States. Are you and your facility prepared for stricter pollutant limits for your air permit renewal, plant expansion, or plans for a new site in a non-attainment area? This presentation will walk you through what you need to know, using the Northern Ohio area as an example, in order to learn how the designation of serious non-attainment for particulate matter and ozone can affect your facility.
