does it cost for yard trimmings? Or is there a place just to take yard trimmings?

Yes- there is a fee to drop off yard trimmings at the Trans-Jordan Landfill. For a load to qualify as “green waste disposal” the entire load must be clean green waste (no contamination). $8.00 minimum for all regular trucks and trailers or $17.00 per ton All loads must be secured and covered to avoid a double charge

Trans Jordan does take green waste no dirt sod plastic or metal to qualify there is a small fee per ton I believe its 8.00. Depending on where your coming from of your up north you can go to sl county landfill there's also diamond tree on 500 west and about 3500 south the prices vary
