Biosolids; directing certain entity to disclose biosolid use on certain property. Effective date.

This bill requires businesses selling agricultural products like compost, fertilizer, or mulch to clearly label if they contain biosolids (treated wastewater byproducts). It also mandates property owners to display visible public signage where biosolids were applied and disclose this when selling or leasing land. The Department of Environmental Quality must publish an annual public map showing all biosolids application sites, including dates and landowner names. These rules apply to all agricultural product sales, property transactions, and agritourism businesses within four miles of application sites.
