bThe boundaries for these designated areas are based on coordinates of latitude and longitude derived from EPA Region 9’s GIS database 

and are illustrated in a map entitled ‘‘Eastern San Diego County Attainment Areas for the 8-Hour Ozone NAAQS,’’ dated March 9, 2004, including an attached set of coordinates. The map and attached set of coordinates are available at EPA’s Region 9 Air Division office. The designated 

areas roughly approximate the boundaries of the reservations for these tribes, but their inclusion in this table is intended for CAA planning purposes only and is not intended to be a federal determination of the exact boundaries of the reservations. Also, the specific listing of these tribes 

in this table does not confer, deny, or withdraw Federal recognition of any of the tribes so listed nor any of the tribes not listed. 1This date is June 15, 2004, unless otherwise noted.
