precursors, and air toxics.
Localities failing to meet the NAAQS for a particular criteria pollutant
over a three-year period are subject to classification as a nonattainment area.

This approach is consistent with how regulatory agencies have traditionally evaluated the benefits of reducing criteria pollutant
This rule will limit diesel particulate matter and criteria pollutant
