Abstract
The Environmental Protection Agency (EPA) is approving a submittal by the Washington Department of Ecology (Ecology) 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 lead (Pb) on October 15, 2008 and nitrogen dioxide (NO<INF>2</INF>) on January 22, 2010. Specifically, Ecology conducted an emissions inventory analysis and reviewed monitoring data to show that sources in Washington do not significantly contribute to nonattainment or interfere with maintenance of the 2008 Pb and 2010 NO<INF>2</INF> NAAQS in any other state.
