Probably, an ice-eater or aqua-therm permit and fee would be issued by the town, so it's a state statute, and the town can choose whether or not to issue permits.
Most likely, people know when they have too much splish-splash going on, and will adjust it on their own, without having their neighbors 'dime-ing' them out by calling in the splish-splash police.
"Look-ee here neighbor ...... you all just got too much splish-splash going on ..... you all want to be down-sizing your splish-splash ..... or, I will notify the splish-splash police ...... you get the message!" ...
