Speaking of Appropriations Riders. . .

Grist mulls over the possibility that Congress might use an appropriations rider to kill EPA authority to regulate GHGs under the mobile source and BACT provisions of the Clean Air Act, in response to Monday's revelation that EPA's endangerment finding had been sent to the White House. You can read the piece here.

[Proviso: I disagree with many of the Grist piece's characterizations of the Mass v. EPA decision; it is not quite as slam-dunk in "requiring" GHG regulation under the CAA as the piece makes it out to be.]

It is certainly true that even Democrats have been making a lot of noise about taking away EPA's Clean Air Act Authority over GHGs as a condition of creating a new climate bill. (You can see this in questioning of Lisa Jackson by the Senate Environment and Public Works committee a few weeks ago, detailed in this post.) But unilaterally getting rid of EPA CAA authority over GHGs without passing a climate bill would be pretty shocking. And I for one believe (hope?) that the White House knows what its doing, and that Congress won't be able to kill EPA authority through an appropriations rider. This can be seen in the way that the White House and EPA have broken the endangerment finding process into digestible bits--making the finding, for instance, but not creating the concomitant regulations of vehicle GHG emissions--and has been feeding those bits slowly to Congress at strategic moments--just before Kerry-Boxer was introduced, just before Ban Ki-moon's visit--to keep it moving along. (For a good overview of how this has been trucking along since last spring, see the "Climate Change" section of Ohio Environmental Law Blog, here.)
