(1) States were not included if respective counties got a grade of B or better for the 24-hour standard and a Passing grade for the annual standard.
(2) The weighted average was derived by counting the number of days in each unhealthful range (orange, red, purple) in each year (2001-2003), multiplying the total in each range by the
assigned standard weights (i.e., 1 for orange, 1.5 for red, 2.0 for purple), and calculating the average.
(3) Grades are assigned by weighted average as follows: A=0.0, B=0.3-0.9, C=1.0-2.0, D=2.1-3.2, F=3.3+.
(4) 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, October 12, 2005. An asterisk (*)
indicates that sufficient data were not available to grade that county.
(5) Grades are based on EPA’s determination of meeting or failure to meet the NAAQS for annual PM2.5 levels during 2002-2004. Counties meeting the NAAQS received grades of Pass; counties
not meeting received grades of Fail.
