One person's effective, efficient job in keeping the environment as clean as possible is another person's out of control bureaucracy.
But it highlights the key psychological difference between progressives and right-wingers. Progressives want to look out for people beneath them on the totem pole of life. Right-wingers, typically people with authoritarian personalities, defer to and seek to protect the interests of people at the top of the totem pole (even when this goes against rational self-interest).
"Most men with nothing would rather protect the possibility of becoming rich than face the reality of being poor - and that is why they will follow us."
Most people I know who are "right wingers" are either people of modest means who have strong religious convictions, disaffected people hurt by the mediocre economy, or small businesspeople who feel that their ability to prosper (or even continue) in business is being choked by unnecessary over-regulation.
Very few care a whit about the "people at the top" you feel that the right wing is protecting.
I know that there are many conservatives in talk radio, and probably a lot of them in the conservative movement, who look up to the "people at the top", and may want to see them protected for some reason.
But you get out among the actual people in day-to-day life who are conservative, most of them just want a fair shake at a decent job, or a chance to build and prosper their small business without having to take all the extra time to keep track of all the paperwork.
And it's not just the EPA. The EPA is just one of the more obvious regulation agencies -- it's a popular target because everybody knows about the EPA. The IRS is another one. Everybody knows about it, so it is also used as an example.
But most of the regulation that affects people -- especially small business -- is on the local level. When I hear small businesspeople talk about "government regulation", they may mention the big national agencies like the IRS and EPA, but the actual regulative mechanisms they are complaining about are on the local and State level, not Federal.
