any Indian country in each county or area, unless otherwise specified. 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.
2 This date is August 3, 2018, unless otherwise noted.
3 EPA revised the nonattainment boundary in response to a court decision, which did not vacate any designations for the 2015 ozone NAAQS, but which remanded the designation for the identified county. Because this additional area is part of a previously designated nonattainment area, the associated implementation dates for the overall nonattainment area e.g., the August 3, 2021 attainment date remain unchanged regardless of this later designation date.

by removing the entry Dona Ana County Sunland Park Area, NM and adding the entry El Paso-Las Cruces, TXNM in its place to read as follows:
