The bill amends several sections of the Revised Code of Washington (RCW) related to the management and testing of biosolids, specifically addressing the presence of PFAS (per- and polyfluoroalkyl substances) chemicals. Key changes include the insertion of new definitions, such as "PFAS chemicals," and the establishment of a timeline for the Department of Ecology to implement sampling and testing requirements for biosolids by July 1, 2028. Additionally, the department is required to analyze the levels of PFAS chemicals in biosolids produced in Washington by July 1, 2029, and submit a report with recommendations to the legislature by December 1, 2029.

The bill also emphasizes the importance of public involvement in the rule-making process by requiring the department to consult with an advisory committee composed of various stakeholders, including representatives from the farming community, toxicologists, and local governments, before adopting or amending any rules related to PFAS testing. Furthermore, it modifies existing provisions regarding the management of biosolids, ensuring that the program aligns with federal regulations and includes public input in the permitting process. The bill aims to enhance the safety and management of biosolids while addressing potential public health risks associated with PFAS chemicals.
