Once a week or so we see diesel or something else spilled from one of them. We're probably talking many gallons, too. I don't think I've ever seen any of them fined.
Of course not, that would make to much sense...kind of like banning that awful copper from "recreational boats, under 65'".....while a week later we find hospitals are going to use copper sheeting to "kill germs, eliminate MRSA" and other things...
Bad or not bad? Matters not to the powers that be....and the enforcers. They are busy siting people on the lakes for not having their un-used sinks plugged...you no, NO discharges
