KEY: B = the nonattainment year was prior to 1995; ppm = parts per million.

NOTES: Nonattainment areas do not meet the national primary or secondary ambient air quality standard for the specified pollutant. Nonattainment areas are classified based on design values: moderate = an area with a design value of 9.1 up to 16.4 ppm.
