On December 7, EPA Administrator Lisa Jackson announced that the agency was finalizing its “Endangerment finding” that greenhouse gases (GHG) endanger the public’s health and welfare.   The finding now requires EPA to regulate GHG under the Clean Air Act (CAA), and allows the agency to finalize the GHG standards proposed earlier this year for new light-duty vehicles as part of a joint rulemaking with the Department of Transportation.

Significantly, this vehicles rulemaking may be the most significant of all of the pending GHG rulemakings because it will trigger Prevention of Significant Deterioration (“PSD”) controls for GHG emissions at least a million stationary sources throughout the United States that had never before been subject to Clean Air Act regulation.

It will become effective 30 days after it is published in the Federal Register.
