## Abstract

The Environmental Protection Agency (EPA) is taking final action to approve a submittal by the Idaho Department of Environmental Quality (Idaho DEQ) demonstrating that the State Implementation Plan (SIP) meets certain interstate transport requirements of the Clean Air Act (CAA) for the National Ambient Air Quality Standards (NAAQS) promulgated for nitrogen dioxide (NO<INF>2</INF>) on January 22, 2010. Specifically, the Idaho DEQ reviewed monitoring and modeling data to show that sources within Idaho do not significantly contribute to nonattainment, or interfere with maintenance, of the NO<INF>2</INF> NAAQS in any other state.
