The federal government is the worst polluter in this country, by a wide margin.
There is no way we should also be entrusting it to also be our environmental steward.
The EPA needs to be defunded, and let the states do that work instead.
Every state but Alaska and Iowa has authorization to perform oversight of at least some Hazardous Waste cleanup, even at federal-government facilities.
Much of EPA's hazardous-waste-regulation funding goes to states in the form of grants based on how many facilities they have. But states often need more horsepower than they have, so they lean on technical and regulatory expertise from the federal level.
Plus, some sites cross state/tribal lines. For example, groundwater plumes don't just stop at political boundaries.
Yeah, EPA needs
very strong pruning, but it would be an inefficient mess to get rid of it or defund too much.
