While this general welfare clause has been expanded over the years, it still fails on several levels. The courts have only allowed the general welfare clause to be used with the taxing and spending powers of congress. No court and no competent constitutional authority has ever said it extends congress's powers to create departments that can make law independent of congress or constitutional processes nor have they used the clause to establish fines and/or imprisonment terms to anyone. There is simply no constitutional basis for it.
It is your reading comprehension that needs adjusting. The departments don't create the law. They enforce it. That is what I said. It was Congress that created the department as the Constitution allows.
Can congress create a department of the second amendment, staff it with a bunch of people who create regulation saying you have to own at least 3 guns per person in the household, molest your children at least once in their life time, spin in circles twice before taking a piss all without congressional action? Can the EPA make any of these regulations? The answer is no to all because there is no constitutional authority for it. The only difference is how silly the regulations might be but the general welfare claim can be made just the same.
Again, it isn't the EPA creating the regulations. It is Congress. The EPA is merely enforcing the regulations that Congress created. If you want to know the specific act it is NEPA. I leave it as an exercise for you to look it up.
The rest of your post is totally nonsense repeating the same line you refused to understand... Namely that Congress created the EPA and Congress has the power to destroy it. But know the consequences when you do. Things like the Gulf spill will go unaddressed. The Freedom Enterprises MCHM spill would have no legal recourse. The impoundment failure in Tennessee would be common place. Not to mention Love Canal...
