Information pertaining to areas of Indian country in this table is intended for Clean Air Act planning purposes only and is not an EPA determination of Indian country status or any Indian country boundary. EPA lacks the authority to establish Indian country land status, and is making no determination of Indian country boundaries, in this table. 4 [Reserved] 5 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.
