See Code of Federal Regulations, Section 40 Part 81, for detailed information about Ambient Air Quality Standards. This data set is specifically designed for use with ArcGIS and related software. Data may be used for reference to boundaries of attainment areas in Region 9. This layer is presented in the WGS84 coordinate system for web display purposes. Downloadable data are provided in native coordinate system or projection.
