**SUPPLEMENTARY INFORMATION:**
EPA published a final rule document on June 2, 2014, (79 FR 31566) updating 40 CFR part 81, “Designation of Areas for Air Quality Planning Purposes” for the 1997 and 2006 PM <sub>2.5</sub> NAAQS nonattainment areas. This final rule included revisions to 40 CFR 81.350 to remove the tables titled “Wisconsin—PM <sub>2.5</sub> (Annual NAAQS)” and “Wisconsin—PM <sub>2.5</sub> [24-hour NAAQS]” and to add three tables titled “Wisconsin—1997 Annual PM <sub>2.5</sub> NAAQS (Primary and Secondary)” and “Wisconsin—1997 24-hour PM <sub>2.5</sub> NAAQS (Primary and Secondary)” and “Wisconsin—2006 24-hour PM <sub>2.5</sub> NAAQS (Primary and Secondary)”. The entry for the Milwaukee-Racine designated area in the Wisconsin—2006 24-hour PM <sub>2.5</sub> NAAQS table erroneously indicated that the area was designated as nonattainment when, in fact, the area had been redesignated to attainment status on April 22, 2014. 79 FR 22415. Therefore, the entry for the Milwaukee-Racine area is being corrected to reflect the correct attainment designation.
