(1) This list represents cities with the lowest levels of annual PM2.5 air pollution.
(2) Cities are ranked by using the lowest design value for any county within that metropolitan area.
(3) The Design Value is the calculated concentration of a pollutant based on the form of the national ambient air quality standard, and is used by EPA to determine whether or not the air quality in a county meets the standard. The source for the Design Values is EPA, communication from the Office of Air Quality Planning & Standards, Mark Schmidt, February 1, 2005.
