More rumblings that EPA may move forward with regulation of greenhouse gases under its existing authority under the Clean Air Act.  It appears EPA has started to rattle its saber in an effort to re-energize the cap-and-trade proposal currently in the Senate.

The San Francisco Chronicle reported that Administrator Lisa Jackson said the "endangerment finding" would be issued in the next few  months

Lets get everyone up to speed with events on regulation of greenhouse gases (GHGs) including CO2:

1.  Supreme Court says CO2 is a pollutant under the Clean Air Act.  In Massachusetts v. EPA decided in April of 2007, the Supreme Court held that GHGs are pollutants that may be regulated under the Clean Air Act.  But

For the first time a court has revoked a permit due to concerns over C02 emissions and climate change.  While there have been previous instances where states have denied permits due to concerns with C02 emissions, this is the first time a court has revoked a previously issued permit.  Notably, the Court did not base its decision on state law, rather it ruled the Clean Air Act (CAA) requires analysis and control of C02 emissions. 

Other courts are currently hearing similar challenges.  If this decision is a trend it will have major implications for any new facilities seeking an air permit.  In a future blog post I will discuss the implications of using the Clean Air Act, specifically the New Source Review provisions, to regulate CO2.  Much speculation has been made as to whether CO2 will be regulated even without action by Congress on comprehensive climate change legislation.

The CO2 decision was issued on June 20, 2008 in Georgia’s Fulton County Superior Court.  The Georgia Environmental Protection Division had approved a permit for the construction of a proposed 1200-megawatt coal-fired power plant.   Environmental groups, including the Sierra Club, challenged the permit saying the plant’s emission of 8-9 million tons of CO2 had to be considered. Siding with the Sierra Club, the Court overturned the State’s issuance and sent the permit back to perform the analysis it said was required under the CAA. 

Note: According to Sourcewatch, between 2007 and 2008, plans for 69 coal plants have been canceled.Continue Reading First Court Revokes Air Permit Over CO2 and Clean Air Act
