Yes thanks to Bill Clinton and ALGORE they passed a enviromental bill that count particulates in the air. all states will be conforming to a standard similar to the current Cali laws. Including lawn mowers , all 2 stroke motors will be required to either have a cat or be 2006 compliant, That is why the push for 4 stroke outboard motors on boats, Hell if Farming equipment kicks up a bunch of dust when fed regulators are there they can be fined for discharge of excessive particulates into the atmosphere. All 50 states will comply or face severe penality and loss of federal money
