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 definition of "biosolids" to encompass municipal sewage sludge that can be beneficially recycled, and the introduction of specific requirements for facilities generating biosolids to sample for PFAS chemicals. By July 1, 2026, the Department of Ecology is mandated to publish guidance on PFAS sampling requirements, and facilities must adhere to these guidelines, conducting tests at least quarterly starting January 1, 2027, until June 30, 2028. Additionally, the department is required to report on the levels of PFAS in biosolids by July 1, 2029.

The bill also establishes an advisory committee to consult with various stakeholders, including the farming community and toxicologists, to ensure comprehensive input on biosolid testing standards. Furthermore, it modifies the fee structure for biosolid permits to include costs associated with sampling and testing, while ensuring transparency in the department's financial activities related to biosolid management. Overall, the legislation aims to enhance public health protections and environmental safety concerning the management of biosolids in Washington State.
