Kathleen D'Agostino, Environmental Scientist, Attainment Planning and Maintenance Section, Air Programs Branch (AR-18J), Environmental Protection Agency, Region 5, 77 West Jackson Boulevard, Chicago, Illinois 60604, (312) 886-1767, *[email protected]* .
**SUPPLEMENTARY INFORMATION:**
EPA published a final rule document on December 19, 2016, (81 FR 91841) updating 40 CFR part 81, “Designation of Areas for Air Quality Planning Purposes” for the 2008 8-Hour Ozone NAAQS. This final rule included a revision to 40 CFR 81.350 reclassifying the Sheboygan, Wisconsin area (Sheboygan County) as “moderate” nonattainment for the 2008 ozone NAAQS. The entry for the Sheboygan County designated area in the Wisconsin-2008 8-Hour Ozone NAAQS (Primary and secondary) table erroneously indicated that the effective date of the classification is January 18, 2017 when, in fact, the effective date should have been December 19, 2016. 81 FR 91846. Therefore, the entry for the Sheboygan County area is being corrected to reflect the correct classification date.
