Abstract
The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the State of Rhode Island. This revision establishes the regulation of fine particulate matter (that is, particles with an aerodynamic diameter less than or equal to a nominal 2.5 micrometers, generally referred to as "PM<INF>2.5</INF>"), PM<INF>10</INF> (particles with an aerodynamic diameter less than or equal to a nominal 10 micrometers), and nitrogen oxides (NO<INF>X</INF>) within the context of Rhode Island's Prevention of Significant Deterioration (PSD) permitting program. The EPA is also approving other minor changes to Rhode Island's PSD permitting program. In addition, EPA is converting several conditionally approved infrastructure SIP elements to fully approved elements for the 2008 ozone, 2008 lead, 2010 nitrogen dioxide, and 1997 and 2006 PM<INF>2.5</INF> National Ambient Air Quality Standards (NAAQS). These actions are being taken in accordance with the Clean Air Act.
