## Abstract

The Environmental Protection Agency (EPA) is taking direct final action to approve the 2011 base year inventories for the five Pennsylvania marginal nonattainment areas for the 2008 8-hour ozone national ambient air quality standard (NAAQS), the Allentown-Bethlehem- Easton, Lancaster, Pittsburgh-Beaver Valley, and Reading nonattainment areas and the Pennsylvania portion of the Philadelphia-Wilmington- Atlantic City nonattainment area. The Commonwealth of Pennsylvania submitted the emission inventories to meet the nonattainment requirements for marginal ozone nonattainment areas for the 2008 8-hour ozone NAAQS. EPA is approving the 2011 base year emissions inventories for the 2008 8-hour ozone NAAQS as a revision to the Pennsylvania State Implementation Plan (SIP), in accordance with the requirements of the Clean Air Act (CAA).
