Air Plan Approval; Rhode Island; Infrastructure State Implementation Plan Requirements for Particle Matter, Ozone, Lead, Nitrogen Dioxide and Sulfur Dioxide

The Environmental Protection Agency (EPA) is approving most elements of State Implementation Plan (SIP) submissions from Rhode Island regarding the infrastructure requirements of the Clean Air Act (CAA or Act) for the 1997 fine particle matter (PM<INF>2.5</INF>), 2006 PM<INF>2.5</INF>, 2008 lead (Pb), 2008 ozone, 2010 nitrogen dioxide (NO<INF>2</INF>), and 2010 sulfur dioxide (SO<INF>2</INF>) National Ambient Air Quality Standards (NAAQS). Additionally, EPA is disapproving the submissions with respect to CAA section 110(a)(2)(H), for which a Federal Implementation Plan has been in place for this requirement since 1973. EPA is also correcting an earlier approval of this element for the 1997 8-hour ozone NAAQS infrastructure requirements. Finally, EPA is approving several statutes submitted by Rhode Island in support of their demonstration that the infrastructure requirements of the CAA have been met. Lastly, EPA is conditionally approving certain elements of Rhode Island's submittal relating to Prevention of Significant Deterioration (PSD) requirements.
