°ÄÃÅÁùºÏ²Ê¿ª½±Ô¤²â of America urged the U.S. Environmental Protection Agency to not issue a final endangerment finding that current concentrations of greenhouse gas (GHG) emissions in the atmosphere endanger public health and welfare and that new motor vehicles (and engines) contribute to this endangerment.  An endangerment finding under the Clean Air Act (CAA) would open the door for EPA to control GHG emissions under the Act.  °ÄÃÅÁùºÏ²Ê¿ª½±Ô¤²â took the opportunity in this comment period to resubmit its November 26, 2008 comment letter to the agency regarding its advanced notice of proposed rulemaking for regulating GHG emissions under the CAA.  In that letter, °ÄÃÅÁùºÏ²Ê¿ª½±Ô¤²â maintained that the CAA is the wrong tool to regulate GHG emissions and identified several onerous regulatory programs in the Act that would be triggered should EPA regulate GHG emissions under any section of the Act.  In its June 23^rd comment letter on the proposed endangerment finding, °ÄÃÅÁùºÏ²Ê¿ª½±Ô¤²â argued that the disastrous implications of regulating GHG emissions under the CAA would provide EPA with a "reasonable explanation as to why it will not exercise its discretion to determine whether GHGs contribute to climate change."  The Supreme Court ruling, which charged EPA to reevaluate its decision not to regulate GHGs, did not go so far as to require EPA to make an endangerment finding determination.  °ÄÃÅÁùºÏ²Ê¿ª½±Ô¤²â also urged the agency to postpone its regulatory efforts in light of the fact that legislators are actively working to address GHG emissions.  EPA should allow Congress to act with policy specific to GHGs, instead of trying to force the CAA to address a pollutant that it was not intended to control.
