## Abstract

The Environmental Protection Agency (EPA) is approving Wisconsin's December 23, 2015, state implementation plan (SIP) revision to the Milwaukee-Racine-Waukesha (Milwaukee), Wisconsin 2006 24-Hour Particulate Matter (PM<INF>2.5</INF>) maintenance plan. This SIP revision establishes new Motor Vehicle Emissions Budgets (MVEB) for Volatile Organic Compounds (VOC) for the years 2020 and 2025. The MVEBs for Oxides of Nitrogen (NO<INF>X</INF>), Sulfur Dioxide (SO<INF>2</INF>), and PM<INF>2.5</INF> will remain the same. EPA is approving the allocation of a portion of the safety margin for VOC in the PM<INF>2.5</INF> maintenance plan to the 2020 and 2025 MVEBs. The 2020 and 2025 total year emissions of VOC for the area will remain below the attainment level required by the transportation conformity regulations.
