    dct:description "The Nonattainment Area - Nitrogen Dioxide (NO2-1971) dataset was updated on June 30, 2025 by the Environmental Protection Agency (EPA) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). This dataset provides detailed information about the nonattainment area for the Nitrogen Dioxide (1971) National Ambient Air Quality Standards (NAAQS). On September 22, 1998 the only Nitrogen Dioxide (1971) nonattainment area was redesignated to maintenance. These data are weekly from an OAQPS internal database. However, that does not necessarily mean the data have changed. For more information about this non-attainment area, please see the website https://www.epa.gov/green-book/green-book-nitrogen-dioxide-1971-area-information. A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/1529064" ;
