## Abstract

The Environmental Protection Agency (EPA) is taking direct final action to approve elements of a State Implementation Plan (SIP) submission from the State of Nebraska addressing the applicable requirements of Clean Air Act (CAA) section 110 for the 2010 Nitrogen Dioxide (NO<INF>2</INF>) and Sulfur Dioxide (SO<INF>2</INF>) National Ambient Air Quality Standards (NAAQS), and the 2012 Fine Particulate Matter (PM<INF>2.5</INF>) NAAQS, which requires that each state adopt and submit a SIP to support implementation, maintenance, and enforcement of each new or revised NAAQS promulgated by EPA. These SIPs are commonly referred to as "infrastructure" SIPs. The infrastructure requirements are designed to ensure that the structural components of each state's air quality management program are adequate to meet the state's responsibilities under the CAA.
