Great. The EPA needs to be reigned in significantly, as it is currently an out of control monster bent on "de-industrializing" the US and making China the number one economy sooner rather then later. It also needs to have its funding cut by 50% (2008 levels would actually be a 59% cut I think).
And I think its wonderfull that we can take that useless Global Warming Committee and put it to good use, before utlimately abolishing it.
What enumerated power does the EPA draw its' power from?
The commerce clause. Environmental degradation has repeatedly been shown to have large effects on interstate, Indian, and international commerce.
The EPA has no real power, it's not a branch of government.
Under the Necessary and Proper Clause, it has long been recognized that Congress may create agencies to carry into execution its powers on a particular subject.
