## Abstract

EPA is approving a State Implementation Plan (SIP) revision submitted by the State of Delaware on March 14, 2012. This SIP revision pertaining to Delaware's Prevention of Significant Deterioration (PSD) and nonattainment New Source Review (NSR) programs incorporates preconstruction permitting requirements for fine particulate matter (PM<INF>2.5</INF>) into the Delaware SIP. In addition, EPA is approving SIP revisions and portions of SIP submissions for the purpose of determining that Delaware has met its statutory obligations with respect to the infrastructure requirements of the Clean Air Act (CAA) which relate to Delaware's PSD permitting program and are necessary to implement, maintain, and enforce the 1997 national ambient air quality standards (NAAQS) for PM<INF>2.5</INF> and ozone, the 2006 PM<INF>2.5</INF> NAAQS, and the 2008 lead NAAQS. EPA is approving these revisions in accordance with the requirements of the Clean Air Act (CAA).
