We reported previously on U.S. EPA's proposed finding that greenhouse gas (GHG) emissions are pollutants that endanger the public's health and welfare (a first step to potential regulation under the Clean Air Act). Comments were due yesterday, and can be found here (search Docket No. EPA-HQ-OAR-2009-0171). Just a quick look at the docket suggests that hundreds of comments were filed.
[Update: There is a controversy brewing over whether EPA suppressed internal documents challenging its decision to move forward with the endangerment finding. See here for a good roundup of the issue (CBS News Political Hot Sheet). Also, you can find what may be the source of the controversy here (including the internal EPA emails and study) at the Competitive Enterprise Institute. Interesting. (Moved up.)]
