Abstract
The Environmental Protection Agency is taking final action to correct an error in the initial delineation of the boundary of the Yakima County nonattainment area (Yakima NAA) for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM-10). This correction revises the boundary of the Yakima NAA to exclude a small portion that lies within the exterior boundary of the Yakama Indian Reservation. The excluded area will revert to an unclassifiable designation, consistent with the original and current designation of the Yakama Indian Reservation.
