While doing weekly yard work, part of my routine is to spread my grass clippings over an area in my back yard that is bare with dirt. I then run my automatic sprinklers to keep it all down. I do this by pulling a 5ft harrow behind my 4-wheeler. It can get a little dusty when I'm doing this and blow onto the property across the road. My neighbor is mad as ever about the occassional dust I stir up while doing this. I try to do this when the breeze blows the opposite direction, but that isn't always the case. Am I at legal risk for dust blowing into his yard from mine? We live in a rural area where everyone has 2 acres or more and farming is being conducted just down the road from us.What is the name of your state (only U.S. law)?
