The bill amends several sections of the Revised Code of Washington (RCW) related to the management and testing of biosolids, specifically focusing on the presence of PFAS (per- and polyfluoroalkyl substances) chemicals. Key changes include the establishment of a biosolid management program that aligns with federal regulations and the introduction of specific requirements for sampling and testing biosolids for PFAS chemicals. The Department of Ecology is tasked with publishing guidance on PFAS sampling requirements by July 1, 2026, and facilities generating biosolids must adhere to these guidelines, including quarterly testing starting January 1, 2027, and reporting results by September 30, 2028.

Additionally, the bill creates an advisory committee to consult with various stakeholders, including the farming community and toxicologists, to ensure comprehensive input on the standards for PFAS testing in biosolids. The legislation also modifies definitions and clarifies the roles of local governments and the Department of Ecology in managing biosolids, emphasizing the importance of public health and environmental safety. The bill aims to enhance the regulatory framework surrounding biosolids management while addressing potential risks associated with PFAS chemicals.
