The Environmental Protection Agency (EPA) is proposing to approve revisions to the State of Rhode Island's State Implementation Plan (SIP) relating to 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 proposing to take action on other minor changes to Rhode Island's PSD permitting program. In addition, EPA is proposing to convert several conditionally approved infrastructure SIP elements to fully approved elements in relation to the 2008 ozone, 2008 lead, 2010 nitrogen dioxide and the 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 (CAA).
