Yesterday, the U.S. Environmental Protection Agency issued its decision that stationary sources will not be required to get federal permits under the Clean Air Act for greenhouse gases (GHGs) before January 2011. According to EPA Administrator Lisa P. Jackson, “This is a common sense plan for phasing in the protections of the Clean Air Act. It gives large facilities the time they need to innovate, governments the time to prepare to cut greenhouse gases.” Jackson also announced that during the latter half of 2011 and 2013, the threshold for permitting will be raised “substantially higher” than the originally proposed 25,000-ton limit, with the smallest sources exempted from Clean Air Act permitting requirements until at least 2016.
