Usually what you do for your own use on your own property is very difficult to Federally regulate under the constitution. Local state and county laws or ordinances can be different, especially if your property is in an incorporated city area. Given the sparse and mostly rural use of these engines, and the small scale of their effects, I can't see any real "public" benefit from restricting the use of the Listers. This is a general requirement for Federal regulation under the Constitution.
That said, the previous administration would have done away with our constitution if they could have gotten away with the deed.
Now Scott Pruit, the guy now in charge of the EPA, in his previous role once filed numerous lawsuits against the EPA. There's hope here! Way back in his early local political career, I had spoken with him a few times on various issues. I always got the impression he was a pretty down to earth and practical person with lots of good common sense. We'll have to wait and see what he does in the long run with that EPA agency. I know the Sierra club hates him, which is actually a good sign. Maybe he has some common sense changes in mind for the future. Trump, his boss, would just as soon do away with the EPA all together.
