Show Summary Details

Quick Reference

A geographical area in which levels of a criteria air pollutant meet the national ambient air quality standard for that pollutant. An area may have an acceptable level for one criteria air pollutant but not for others, so it could be both an attainment and a non‐attainment area at the same time. See non‐attainment area.
