Biosolids; prohibiting certain land application. Emergency.

This bill prohibits the land application, sale, or distribution of biosolids (wastewater treatment byproducts) containing perfluoroalkyl substances (PFAS) on agricultural land in Oklahoma. It specifically bans materials like sewage sludge, compost made with sludge, or fertilizers derived from sludge, with limited exemptions for food-processing byproducts (e.g., spent grain from brewing) and animal manure. The Oklahoma Department of Environmental Quality and Agriculture must enforce the ban, develop PFAS remediation plans for affected farmers, and submit reports by February 2027 detailing implementation and costs. The law targets PFAS contamination risks in soil and crops while allowing alternative agricultural materials to be used.
