EPA is not determining the boundaries of any area of Indian country in this table, including any area of Indian country located in the larger designation area. The inclusion of any Indian country in the designation area is not a determination that the state has regulatory authority under the Clean Air Act for such Indian country. The lands of the Navajo Nation, including those lands located geographically within New Mexico, are excluded, as they are separately designated under Section 81.303.
