At most Gov't cleanup sites, I have been to several sad to say we trained at a couple, this is a huge issue that will not go away anytime soon. This is why the American people have to watch what the Gov't does.
Just to play devils advocate, maybe the waste is in the specs to change the classification, I don't know, but personally I do not think that is the case. @
Just AnotherPerson, I think you are right to be concerned and I think you should push your state Gov't to continue the fight, along with that I suggest that you push all of your states members of congress in both houses on this as well. Then of course the courts are always an option for locals, not an easy one but that is why they are there.
The only problem I see with you post is the attempt to say Trump is doing this, while yes he is the POTUS, this process was going on for years and this kind of thing has happened the entire time as well, A great many more sights have been downgraded than cleaned up completely, and the number of sites continue to grow.
In perspective do you think Clinton was guilty of environmental crimes when in 1995 funding for cleanups dropped significantly after taxes on the industries that create the sites expired. If so Bush Jr and Obama would also be as they did little to nothing to reinstate that. To his Credit Obama did weakly try to reinstate them in 2009 and did fund some cleanup in his stimulus but that was a trickle compared to the original funding. I will also add that it is now up to Trump to push Congress to better fund cleanup, but it is also up to every American to do the same.
