Reclassification of the Sheboygan, Wisconsin Area To Moderate Nonattainment for the 2008 Ozone NAAQS

Riepilogo

The Environmental Protection Agency (EPA) is proposing to determine that the Sheboygan, Wisconsin area (Sheboygan County) has failed to attain the 2008 ozone National Ambient Air Quality Standards (NAAQS) by the applicable attainment date of July 20, 2016, and that this area is not eligible for an extension of the attainment date. EPA is proposing to reclassify this area as "moderate" nonattainment for the 2008 ozone NAAQS. Once reclassified as moderate, the State of Wisconsin must submit State Implementation Plan (SIP) revisions that meet the statutory and regulatory requirements that apply to areas classified as moderate nonattainment for the 2008 ozone NAAQS. EPA is proposing to require submission of the necessary moderate area SIP revisions as expeditiously as practicable, but no later than January 1, 2017.
