## Abstract

The Environmental Protection Agency (EPA) is taking final action to partially approve and disapprove 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 1997 and 2006 National Ambient Air Quality Standards (NAAQS) for fine particulate matter (PM<INF>2.5</INF>), 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. Additionally, EPA is taking final action approving the revocation of the coarse particulate matter (PM<INF>10</INF>) annual standard and adoption of the 24hr PM<INF>2.5</INF> standard.
