<H2 id=cair>About the Clean Air Interstate Rule</H2>
<P><A title=CAIR 
href="http://www.epa.gov/airmarkets/progsregs/cair/index.html">The Clean Air 
Interstate Rule</A> (CAIR) was designed to address interstate transport of ozone 
and fine particulate matter (PM<SUB>2.5</SUB>) pollution. To do so, <SPAN 
class=caps>CAIR</SPAN> required certain states to limit annual emissions of 
nitrogen oxides (NO<SUB>X</SUB>) and sulfur dioxide (SO<SUB>2</SUB>), which 
contribute to the formation of ozone and PM<SUB>2.5</SUB>. It also required 
certain states to limit ozone season NO<SUB>X</SUB> emissions which contribute 
to the formation of ozone during the summer ozone season. <SPAN 
class=caps>CAIR</SPAN> developed three separate <A 
title="EPA's Cap and Trade page" href="http://www.epa.gov/captrade/">cap and 
trade</A> programs that could be used to achieve the required reductions — the 
<SPAN class=caps>CAIR NO</SPAN><SUB>X</SUB> ozone season trading program, the 
<SPAN class=caps>CAIR</SPAN> annual NO<SUB>X</SUB> trading program, and the 
<SPAN class=caps>CAIR SO</SPAN><SUB>2</SUB> trading program. The <SPAN 
class=caps>CAIR NO</SPAN><SUB>X</SUB> ozone season and annual programs began in 
2009, while the <SPAN class=caps>CAIR SO</SPAN><SUB>2</SUB> annual program began 
in 2010. The reduction in ozone and PM<SUB>2.5</SUB> formation resulting from 
implementation of the <SPAN class=caps>CAIR</SPAN> programs provides health 
benefits as well as improved visibility in national parks and improved stream 
quality in the eastern U.S.</P>
<H2 id=litigation>Litigation and the <SPAN class=caps>CAIR</SPAN> Replacement 
Rule</H2>
<P>On July 11, 2008, the U.S. Court of Appeals for the D.C. Circuit issued a 
ruling vacating <SPAN class=caps>CAIR</SPAN> in its entirety. <SPAN 
class=caps>EPA</SPAN> and other parties requested a rehearing, and on December 
23, 2008, the Court revised its decision and remanded <SPAN 
class=caps>CAIR</SPAN> to <SPAN class=caps>EPA</SPAN> without vacatur. This 
ruling leaves <SPAN class=caps>CAIR</SPAN> and the <SPAN class=caps>CAIR</SPAN> 
Federal Implementation Plans (FIPs) — including the <SPAN class=caps>CAIR</SPAN> 
trading programs — in place until <SPAN class=caps>EPA</SPAN> issues new rules 
to replace <SPAN class=caps>CAIR</SPAN>.</P>
<P><SPAN class=caps>EPA</SPAN> is committed to issuing rules to replace <SPAN 
class=caps>CAIR</SPAN> that will help states address the interstate air 
emissions transport problem in a timely way and that fully comply with the 
requirements of the Clean Air Act and the opinions of the D.C. Circuit. <SPAN 
class=caps>EPA</SPAN> has developed a proposed <A title="Transport Rule" 
href="http://epa.gov/airtransport/">Transport Rule</A> which, if finalized as 
proposed, would replace <SPAN class=caps>CAIR</SPAN> in 2012. The proposed rule 
was signed in July 2010.</P><!-- #EndEditable --><!-- BEGIN AREA FOOTER --><!-- ADD TEXT/LINKS FOR AREA FOOTER WITHIN THIS PARAGRAPH TAG -->
