1 See the Air Quality Design Value site spreadsheet footnotes for information about "Insufficient Data" Meets NAAQS Determinations.

Design Values in ppm. "Current Design Values" are current as of the posted Green Book date. Check the Air Quality Design Value site for design value updates.


County subtotals and grand totals may not equal sum of the counties. Part counties are only counted one time within groupings. Multi-state nonattainment areas are counted in totals as maintenance areas when all states in the area have been redesignated. Multi-state areas are counted only once in area totals.
