I suspect the first thing the PaintCare drop-off service does in Maine or Vermont is to ask for a state ID ...... so only people from Maine or Vermont can use their disposal service.
Hellooooo New Hampshire legislature ...... any chance for joining up with
www.paintcare.org?
By not having a service like PaintCare, it ends up with people disposing their old paint into a semi-public trash can, such as at Lowe's, Home depot, Walmart, Irving Gas, or a private dumpster, or the town transfer station. Most everyone wants to do the correct thing with their left-over haz waste, and the existing NH system does not work good because it works to encourage people to dispose into retail trash.
If PaintCare is happening in Maine, Vermont, and Rhode Island, then it should probably happen in New Hampshire, too.
