Where are nonattainment areas?
A geographic area that meets or does better than the primary standard is called an attainment area; areas that don’t meet the primary standard are called nonattainment areas. In some cases, a designated nonattainment area can include portions of 2, 3, or 4 states rather than falling entirely within a single state.
What is attainment vs nonattainment?

What must a city do if their air quality is in non-attainment of the National Ambient Air Quality Standards?
Attainment of Air Quality Standards Nonattainment areas must develop plans to attain the NAAQS, and attainment areas must develop plans to maintain attainment. Failure of a state to reach attainment of the NAAQS by the target date can trigger penalties, including withholding of federal highway funds.
