The compressed area shapefiles listed below were used to generate the maps on this website. They contain the boundary shapes for all of the areas that were designated nonattainment for a standard revision. The external data files contain the current area status information, indicating the reclassification and whether an area is nonattainment or has been redesignated to maintenance at the time of the Green Book posting. The external data files can be linked to the shapefiles through the composID field in each file.
