The Environmental Protection Agency (EPA) is taking final action to approve certain elements of State Implementation Plan (SIP) submissions from the State of Nebraska for the 2010 Nitrogen Dioxide (NO2) and Sulfur Dioxide (SO2) National Ambient Air Quality Standards (NAAQS) and the 2012 Fine Particulate Matter (PM2.5) NAAQS. States are required to have a SIP that provides for the implementation, maintenance, and enforcement of the NAAQS. Whenever EPA promulgates a new or revised NAAQS, states are required to make a SIP submission to establish that they have, or to add, the provisions necessary to address various requirements to address the new or revised NAAQS. 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 Clean Air Act (CAA).
