I have a home on the NJ side of the Hudson River. The towns are NOT allowed to dump plowed snow into the Hudson.
It isn't pure enough, so says the EPA.
There the snow mountains sit, blocking streets, clogging shopping centers, and causing all kinds of misery for those driving in the area.
This is freshly fallen snow. There is no logic at all to the directive but there it is.
Evidently releasing tons of poisonous waste into a river that is sued for recreation, feeding crops, and thereby poisoning drinking water is just fine with the EPA.
