The EPA has been totally out of control. I have covered some of their policy since the early 90s and they would be setting drinking water standards for things like low levels of radium based on data from Hiroshima. I'm talking levels low enough that it competes with eating the occasional banana from a risk factor. Maybe they were right, maybe they were wrong, but the real science just wasn't there. The result was huge water bills with no real scientific justification. They would set the standards so low that it was questionable that you would be able to actually measure for compliance with current technologies. And once a decision was made, that was it. Wrong, right or questionable it was cut in stone. That was the Carol Browner EPA and was one of the sore spots, along with his blanket support of ethanol, for me when AL Gore ran for president.
They do some of the same stuff with gasoline and diesel (though it's more at the retail end than the production end). Generally, though they are fairly restrained except for some new Wetlands regulation that is way too broad. The big problem here is that they have set some standards and requirements but lack the manpower/budget for enforcement. There is money there, billions set aside for such things in principal, but in usage it is kept accumulating to play accounting games with the agency in general (and congress uses the standing balance to make the deficit look lower and doesn’t want to authorize the expenditure of the funds). So most of the enforcement is passed off to the states which typically in even worse shape from a budget standpoint. You actually have the case of the industry being angry about lack of enforcement since most of the established players have gotten with the program (at considerable cost) yet some have not or are only partially complying.
The EPA has gotten better, at least some departments, realizing with petroleum that there is a huge ripple effect for the economy. But, just wait for the new diesel sulfur regs to hit in a couple of years (which Bush supports, BTW). I don’t think anybody, even honchos in the oil industry, know what’s going to happen to supply with that. But that was a case of the automakers solution for emissions reduction winning out over the oil industry, and requiring almost laboratory-grade diesel which really, really compliactes how you distribute fuel.
