This page provides links to maps available throughout the Green Book. Maps are updated as needed each time a new version of the Green Book is posted. Each map contains a month/year date indicating the last time the map was updated for a Green Book posting. Links for new sets of maps will be added to this page as nonattainment areas are redesignated to maintenance for new standards, and as new NAAQS are promulgated.

The maps are downloadable as zipped PDF files. The filenames of the zipped maps includes the date the Green Book was posted. The individual state maps have been generated with ESRI shapefiles for the pollutants areas listed below (these shapefiles are available on the Green Book GIS Downloads web page). Since area shapefiles are not available for standards other than those designated since 2004, maps for older pollutant standards are national maps based on whole county boundaries.
