I have found this:
The annual standard for PM2.5 is met whenever the 3 year average of the annual mean PM2.5 concentrations for designated monitoring sites in an area is less than or equal to 15.0 µg/m3. The 24 hour standard for PM2.5 is met whenever the 3 year average of the annual 98th percentile of values at designated monitoring sites in an area is less than or equal to 35 µg/m3.
In addition to air quality data, EPA guidance on the PM2.5 designations process also discusses other important factors, including emissions of pollutants that lead to PM2.5 formation, population, commuting patterns, and expected growth, that states should evaluate in order to determine whether a county is a likely contributor to the area’s air quality problem.

It seems the linked page above has moved.
Alternatively I found this table. There are primary and secondary standards.
https://www.epa.gov/criteria-air-pollutants/naaqs-table
"Primary standards provide public health protection, including protecting the health of "sensitive" populations such as asthmatics, children, and the elderly. Secondary standards provide public welfare protection, including protection against decreased visibility and damage to animals, crops, vegetation, and buildings."
It is secondary standards (15.0 µg/m3) but not primary standards (12.0 µg/m3) we shall check, is that right?
