Abstract
EPA is approving Wisconsin's revision to its State Implementation Plan (SIP), which updates its ambient air quality standards for fine particulates to conform with current Federal ambient air quality standards for the same criteria air pollutants. EPA received comments on its April 8, 2010, proposed rule and withdrew the accompanying Direct Final Rule. After considering the comments, EPA is approving the revisions to the Wisconsin SIP as requested by the State on September 11, 2009.
