This bill establishes new regulations regarding the land application, sale, and distribution of biosolids and related materials in Oklahoma. It defines key terms such as "biosolids," "perfluoroalkyl and polyfluoroalkyl substances (PFAS)," "sewage sludge," and "septage." The bill prohibits the application or spreading of sludge from municipal, commercial, or industrial wastewater treatment plants, as well as any products derived from such sludge, for agricultural purposes. However, exceptions are made for certain materials, including those disposed of in lined landfills or derived from food processing, provided they do not come from previously treated soil with biosolids.

Additionally, the bill mandates the Department of Environmental Quality to develop a long-term plan to prohibit the land application of septage and to submit a report by February 1, 2026, detailing the capacity of wastewater treatment facilities and recommendations for managing septage. The Oklahoma Department of Agriculture, Food, and Forestry is tasked with creating a plan to assist agricultural producers affected by PFAS contamination, including identifying contamination sources and implementing best practices for remediation. The bill emphasizes collaboration between the two departments for effective enforcement and requires a report on the costs associated with PFAS removal to be included in the general appropriations bill for the next fiscal year. An emergency clause is included, allowing the act to take effect immediately upon passage.
