The states can handle anything useful the EPA is doing, or else we need a Constitutional amendment to authorize the EPA.
States don’t have control of the air that comes and goes, nor do they have control of the water that flows in and out and beyond their borders.
We’re family. We all share the same stuff, but we’re increasing in number and in our demands for and rights to these shared resources.
You fill our packed elevator with your buttgas and your personal dietary choices have now become our shared problem.
So, I don’t have a problem with a federal overseer of fair standards arbitrating where and where needed, because sooner or later it always is needed.
But, I do have a problem when something’s out of control, especially when that something has great power, but few checks and balances.
Like the EPA, for one swampy example.
