Well all those code enforcement minions have it totally wrong.
The problem is not uncontrolled smoke from the pit, it's the uncontrolled wind blowing across you yard/business from the road (which the local government owns). Simple thermodynamics and airflow analysis can show the smoke was forced out of your yard and into the neighbor's area of enjoyment by the movement of heated air which arose from the black asphalt, concrete sidewalks and other thermal masses owned, installed, and maintained by the local governing body. So the code enforcement minions need to ticket the mayor or county manager.
And think of the potential for lawsuits for the illegal encroachment of that unwanted wind across your property! You, my friend, are a victim of wanton government run a muck and should be justly compensated as such.....
