Climate Change: An Update on Legislation v. Regulation

The silence from Congress recently concerning climate change legislation has been deafening. The continued health care debate does not bode well for early passage of the Waxman-Markey bill. Meanwhile, EPA is not sitting on its hands.

Daily Environment Report noted last week that EPA has sent to the OMB a proposal to reverse the Agency’s policy that CO2 is not a pollutant subject to the PSD provisions of the Clean Air Act. Also last week, Greenwire reported that: “As Hill debate flounders, EPA plows ahead on emissions rules.” [And for those of you who can’t get enough of the debate between “founder” and “flounder”, take a look here.] The Greenwire story reports that EPA is moving ahead on rules governing emissions of GHGs from automobiles and large stationary sources.

The biggest debate continues to be whether EPA has legal authority to exempt small sources of CO2 (probably those emitting less than 25,000 tons per year) from PSD rules. Certainly, the D.C. Circuit’s treatment of EPA’s CAIR rule should give everyone pause that the Court will approve rules that don’t seem to have authority in the CAA, just because everyone thinks that the rules would be good public policy. The strongest argument in support of the exemption – or at least the one mentioned most often – is simply that no one would challenge such a rule, because it would obviously be such a good idea. I’m skeptical. Major sources who want to torpedo the entire rule might easily challenge such an exemption.

I hate to sound like a broken record, but I keep coming back to a slightly different question: Who in their right mind would prefer EPA rules under current CAA authority to comprehensive legislation, however imperfect the legislation might be? Those assessing the merits of legislation can’t compare it to the status quo, because, as these recent moves by EPA demonstrate, the status quo cannot hold for long. The comparison must therefore be between the Waxman-Markey bill and the world as it will be once EPA regulates under existing authority.

It’s looking more and more likely that Congress may not have sufficient momentum to pass legislation until the reality of EPA regulation becomes manifest. I’m not looking forward to that.
