Oh you going to play that card? Sure. Tell me, do you think that every single person in your society follows the same rules or are some of them more equal than others?
Zoning is a why to ensure things like hog farms that stink several miles away are not located near people
Jesus. Ok first off this isn’t a problem anymore. We have had odor scrubbers for decades. I know, I have designed and installed them. For situations where that is not appropriate we can often simply crank up the HVAC and do a burn off. For example coffee processing plants will often do that. Still not enough? Ok we can wrap the whole dang thing in a tarp and emit it slowly. Still not working? Cool, let’s put some trees around it and sink it down a meter or two. Odor is not an issue anymore if you put in effort. It hasn’t been for decades.
I have been to wastewater treatment plants in August and could only smell something when my head was directly over the wetwell. You of course know what a wetwell is since you are talking about zoning I am sure. Nope, no need to Google that ;)
Zoning laws are not about odor. They are about Karen’s getting to keep minorities and jobs out of certain areas.
