The bill amends several sections of the Revised Code of Washington (RCW) related to the management of biosolids, which are primarily organic, semisolid products resulting from wastewater treatment. Key changes include the replacement of the term "population increases" with "population growth" and the clarification that the production of biosolids is expected to increase in the future. The bill establishes a program to manage municipal sewage sludge, emphasizing its beneficial reuse while minimizing risks to public health and the environment. It also introduces new definitions, including "PFAS chemicals," and mandates the Department of Ecology to adopt rules for a biosolid management program that aligns with federal regulations.

Additionally, the bill sets specific requirements for PFAS chemical sampling and testing in biosolids, with deadlines for establishing these requirements and completing an analysis of PFAS levels in Washington state biosolids. The Department of Ecology is required to consult with an advisory committee before adopting any rules related to PFAS testing, ensuring stakeholder input. The bill also outlines the establishment of annual fees for biosolid permits, the creation of a biosolids permit account, and the need for transparency regarding fees and expenses related to biosolid management.
