Biosolids; prohibiting land application, spreading, sale, and distribution of certain materials; reporting; remediation; funding policies; emergency.

HB 1726 prohibits the land application, spreading, sale, or distribution of biosolids (treated wastewater solids) and related materials like sewage sludge or septage-derived compost in Oklahoma, except for specific exemptions including food-processing byproducts (e.g., apple or blueberry waste) and animal manure. It holds violators civilly liable for PFAS contamination costs and directs the Department of Environmental Quality to enforce the ban while the Agriculture Department oversees agricultural impacts. The bill requires both agencies to develop long-term plans for safe biosolids management and remediation funding by December 2025, with a report to legislators. This directly affects wastewater treatment facilities, agricultural businesses using biosolids-based products, and landowners who previously applied such materials.
