Federal Agency Actions Following the Supreme Court's Climate Change Decision in 'Massachusetts v. EPA': A Chronology [August 29, 2013]   [open pdf - 333KB]

"On April 2, 2007, the Supreme Court rendered one of its most important environmental decisions. In Massachusetts v. EPA , the Court held 5-4 that greenhouse gases (GHGs), widely viewed as contributing to climate change, constitute 'air pollutants' as that phrase is used in the Clean Air Act (CAA). As a result, said the Court, the U.S. Environmental Protection Agency (EPA) had improperly denied a petition seeking CAA regulation of GHG emissions from new motor vehicles by saying the agency lacked authority over such emissions. This report offers a chronology of major federal agency actions, mainly by EPA, that involve GHGs or climate change and that occurred in the wake of Massachusetts v. EPA. Most of the listed actions trace directly or indirectly back to the decision. Examples include EPA's 'endangerment finding' for GHG emissions from new motor vehicles; the agency's standards for GHG emissions from new motor vehicles; its interpretation of 'pollutants subject to regulation,' the CAA trigger for requiring best available control technology (BACT) for such pollutants in 'prevention of significant deterioration' areas; its guidance for determining BACT for GHG emissions; the 'tailoring rule' (limiting the stationary sources that initially will have to install BACT and obtain CAA Title V permits based on their GHG emissions); and settlements of litigation seeking to compel new source performance standards (NSPSs) for GHG emissions from electric power plants and petroleum refineries. A few agency actions were included solely because of their relevance to climate change and their post- Massachusetts occurrence--for example, EPA's responses to California's request for a waiver of CAA preemption allowing that state to set its own limits for GHG emissions from new motor vehicles, and EPA's monitoring rule for GHG emissions."
