Condensed Nonattainment Areas List(a) (continued) Notes: (a) This is a simplified listing of Classified Nonattainment areas. Unclassified and section 185a nonattainment areas are not included. In certain cases, footnotes are used to clarify the areas involved. For example, the lead nonattainment area listed within the Dallas-Fort Worth ozone nonattainment area is in Frisco, Texas, which is not in Dallas county, but is within the designated boundaries of the ozone nonattain­ ment area. Readers interested in more detailed information should use the official Federal Register citation (40 CFR 81). (b) Names of nonattainment areas are listed alphabetically within each state. The largest city determines which state is listed first in the case of multiple-city nonattainment areas. When a larger nonattainment area, such as ozone, contains one or more smaller nonattainment areas, such as PM10 or lead, the common name for the larger nonattainment area is used. Note that several smaller nonattainment areas may be inside one larger nonattainment area, as is the case in Figure 1. For the purpose of this table, these are considered one nonattain­ ment area and are listed on one line. Occasionally, two nonattainment areas may only partially overlap, as in Figure 2. These are counted as two distinct nonattainment areas and are listed on separate lines. (c) The number of nonattainment areas for each of the criteria pollutants is listed. (d) Population figures (in 1000s) were obtained from 1990 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 “All” column is avoided by only counting the population of the larger nonattainment area. (e) NO2 population same as O3 and CO. (f) Carbon monoxide nonattainment area includes San Francisco county, and parts of Alameda, Contra Costa, Marin, Napa, San Mateo Santa , Clara, Solano, Sonoma counties. (g) Lead nonattainment area is a portion of Franklin township, Marion county, Indiana. (h) Sulfur dioxide nonattainment area is a portion of Boyd county. (i) PM10 nonattainment area is Granite City, Illinois, in Madison county. (j) Lead nonattainment area is Herculaneum, Missouri in Jefferson county. (k) Lead nonattainment area is a portion of Lewis and Clark county, Montana. (l) Ozone nonattainment area is a portion of Dona Ana county, New Mexico. (m)Youngstown has been redesignated for ozone but not the rest of the MSA and the population has been adjusted accordingly. (n) Lead nonattainment area is a portion of Shelby county, Tennessee. (o) Lead nonattainment area is a portion of Williamson county, Tennessee. (p) Lead nonattainment area is Frisco, Texas, in Collin county. Figure A-1. (Multiple NA areas within a larger NA area) Two SO 2 areas inside the Pittsburgh–Beaver Valley ozone NA. Counted as one NA area. Figure A-2. (Overlapping NA areas) Searles Valley PM10 NA partially overlaps the San Joaquin Valley ozone NA. Counted as two NA areas.
