Build several urban based ground separation units in each major metro area, to collect ground level ozone, then pump & eject it into the upper stratospheric levels.
They can reduce ground level ozone pollution, without rewriting the rules; “replenish/repair” the (ozone was never there, it isn't missing) ozone hole; and blow tons of money, employing lots of moonbats.
Just before (say, at the 85-90% complete stage) EPA could pay Greenpeace & Sierra Club to sue them to shut it down due to some unforeseen “environmental damage” of some sort: a win-win-win-win-win for the lunatics!
