KEY: CO = carbon monoxide; NO2 = nitrogen
dioxide; O3 = ozone; Pb = lead; PM-10 = particulate matter smaller
than 10 microns; SO2 = sulfur dioxide; . = all areas in attainment for a
particle or pollutant.

a This is a simplified listing of classified nonattainment
areas. Unclassified and Section 185a (transitional) nonattainment areas are
not included. Names of nonattainment areas are listed alphabetically within
each state. Note that several smaller nonattainment areas may be inside one
larger nonattainment area. In these cases, the smaller nonattainment areas
are listed on the same line as the larger one, and the number of
nonattainment areas are indicated under each pollutant.

b Guam (U.S. territory)

c National
total includes Guam (U.S. territory).

d The number of nonattainment areas for each of the criteria
pollutants is listed. A dot (.) indicates that all areas are in attainment
for that pollutant.

e 1-hour ozone
standard.

f Ozone
nonattainment area is a portion of Dona Ana County, New Mexico.

g Lead
nonattainment area is Herculaneum, Missouri in Jefferson County.

h
Population figures were obtained from
the 2000 census data. For nonattainment areas defined as only partial
counties, population figures for just the nonattainment area were used when
these were available. Otherwise, whole
county population figures were used. When a larger nonattainment area
encompasses a smaller one, double counting the population in the "Total
exposed" column is avoided by only counting the population of the larger
nonattainment area.

The
"Total exposed" values represent estimated population living in
areas that are in nonattainment for at least one pollutant.

NOTE

Reference
numbers 1-124 do not indicate ranking.
