In my own case, my closest neighbor is about 200 yards away, and there is no neighbor where any smoke drifting their direction doesn’t first have to go through a line of trees. While they might smell the smell at times, they never get smoked.
The onus of the regulation will be felt by the people who tend to be most widely spread from their neighbors, where the natural dilution of any pollutants will take care of the problem before others are affected.
It is generally a non-problem, with the exception of some valleys where local ordinances can take care of the problem.
The EPA, typically, is heavy handed in wielding a solution fro a (non)problem that did not need it.
