The next Congress can simply defund the EPA.
Yeah, and who do you think will pay for it? Not the congress critters, you can bet on it
Defunding the EPA doesn't fix the problem. Most of the aspects of the Clean Air Act are enforceable by citizen lawsuit. That includes the things EPA does, the things they dont do (check how many EPA air regs are on a court ordered deadline), and ultimately, every permit for every project that has emissions of anything in the US.
The EPA is nothing more than a head-fake and willing punching bag. The way the CAA is written, all they have to do is wait for the inevitable strict constructionist ruling from a court and go from there.
The only solution is revising the clean air act. Anything less than that is pissing into the wind...
And air is not the only thing. Some of the new stuff under water laws mean the rain puddle on your property might be a "jurisdictional water" subject to regulation under the Clean Water Act.
Same issue - citizen enforced by abdication of Congressional responsibility to an unelected beauracracy...
Personally - I don't blame EPA. I blame Congress.
