EPA Just Makes It Up As It Goes Along

'We don't have the evidence, we can't support the findings, but hey!!  We did it anyway!!'

That's the Clinton/Bush/Obozo Congressionally-funded EPA. 

...McCarthy admitted that EPA cannot produce all of the original data from the 1993 Harvard Six Cities Study (HSC) and the American Cancer Society’s (ACS) 1995 Cancer Prevention Study II, which is currently housed at New York University.
 
Both studies concluded that fine airborne particles measuring 2.5 micrograms or less (PM2.5) – 1/30th the diameter of a human hair – are killing thousands of Americans every year.

These epidemiological studies are cited by EPA as the scientific foundation for clean air regulations that restrict particulate emissions from vehicles, power plants and factories...

Umpty-zillion dollars in expenses and forward-projected costs for EPA regulation, and not a damn thing to justify it.

Never bothered Petri, Sensenbrenner, or Ryan to vote for continuing the money-flow to these clowns, either.
