Approval and Promulgation of Implementation Plans; Oregon: Interstate Transport of Lead and Nitrogen Dioxide
The Clean Air Act (CAA) requires each State Implementation Plan (SIP) to contain adequate provisions prohibiting air emissions that will have certain adverse air quality effects in other states. On October 20, 2015, the State of Oregon made a submittal to the Environmental Protection Agency (EPA) to address these requirements. The EPA is proposing to approve the submittal as meeting the requirements that each SIP contain adequate provisions to prohibit emissions that will contribute significantly to nonattainment or interfere with maintenance of the 2008 lead (Pb) and 2010 nitrogen dioxide (NO2) National Ambient Air Quality Standards (NAAQS) in any other state.
