This bill establishes new regulations regarding the land application, spreading, sale, and distribution of certain materials related to biosolids, specifically targeting sludge generated from municipal, commercial, or industrial wastewater treatment plants and septage. It defines key terms such as "biosolids," "PFAS," "sewage sludge," and "septage," and prohibits the application or sale of these materials for agricultural purposes, with specific exceptions outlined. Notably, the bill allows for the disposal of these materials at lined and monitored solid waste landfills and permits the use of compost derived from food processing and other specified agricultural sources, provided certain conditions are met.

Additionally, the bill mandates the Department of Environmental Quality to develop a long-term plan to prohibit the land application of septage, including an assessment of wastewater treatment capacities and recommendations for managing septage. The Oklahoma Department of Agriculture, Food, and Forestry is tasked with creating a plan to protect agricultural producers from PFAS contamination and to collaborate with them on best practices for remediation. Both departments are required to submit reports to the legislature by specified deadlines, and the bill includes an emergency clause for immediate enactment upon approval.
