The legislature finds that:
Municipal sewage sludge is an unavoidable by-product of the wastewater treatment process;
Population growth and technological improvements in wastewater treatment processes will increase the production of biosolids in the future;
Sludge management is often a financial burden to municipalities and to ratepayers;
Properly managed municipal sewage sludge is a valuable commodity and can be beneficially used in agriculture, silviculture, and in landscapes as a soil conditioner; and
Municipal sewage sludge can contain metals and microorganisms that, under certain circumstances, may pose a risk to public health.
The legislature declares that a program shall be established to manage municipal sewage sludge and that the program shall, to the maximum extent possible, ensure that municipal sewage sludge is reused as a beneficial commodity and is managed in a manner that minimizes risk to public health and the environment.
The purpose of this chapter is to provide the department and local governments with the authority and direction to meet federal regulatory requirements for municipal sewage sludge. The department may seek delegation and administer the sludge permit program required by the federal clean water act as it existed on the effective date of this section.
The definitions in this section apply throughout this chapter unless the context clearly requires otherwise.
"Biosolids" means municipal sewage sludge that is a primarily organic, semisolid product resulting from the wastewater treatment process, that can be beneficially recycled and meets all requirements under this chapter. For the purposes of this chapter, "biosolids" includes septic tank sludge, also known as septage, that can be beneficially recycled and meets all requirements under this chapter.
"Department" means the department of ecology.
"Local health department" has the same meaning as "jurisdictional health department" in RCW 70A.205.015.
"Municipal sewage sludge" means a semisolid substance consisting of settled sewage solids combined with varying amounts of water and dissolved materials generated from a publicly owned wastewater treatment plant.
"PFAS chemicals" has the same meaning as defined in RCW 70A.350.010.
The department shall adopt rules to implement a biosolid management program within twelve months of the adoption of federal rules, 40 C.F.R. Part 503, relating to technical standards for the use and disposal of sewage sludge. The biosolid management program shall, at a minimum, conform with all applicable federal rules adopted pursuant to the federal clean water act as it existed on the effective date of this section.
In addition to any federal requirements, the state biosolid management program may include, but not be limited to, an education program to provide relevant legal and scientific information to local governments and citizen groups.
Rules adopted by the department under this section shall provide for public input and involvement for all state and local permits.
Materials that have received a permit as a biosolid shall be regulated pursuant to this chapter.
The transportation of biosolids and municipal sewage sludge shall be governed by Title 81 RCW. Certificates issued by the utilities and transportation commission before June 11, 1992, that include or authorize transportation of municipal sewage sludge shall continue in force and effect and be interpreted to include biosolids. In addition to the provisions of Title 81 RCW, the biosolid management program must require a biosolids transporter, subject to regulation by the utilities and transportation commission, that is transporting class B biosolids to be used for land application, as defined by the department's rules, to carry a manifest or similar document specifying the class of biosolids being transported.

By July 1, 2026, the department shall establish PFAS chemical sampling or testing requirements for biosolids regulated under this chapter. In developing the sampling or testing requirements, the department shall consult with the advisory committee created in section 6 of this act.
By July 1, 2027, the department shall complete an analysis of the levels of PFAS chemicals in biosolids produced in Washington state and provide a report of the analysis to the appropriate committees of the legislature and members of the public.
For the purposes of this subsection, "biosolids" do not include septic tank sludge, also known as septage.
The department shall establish annual fees to collect expenses for issuing and administering biosolids permits under this chapter. An initial fee schedule shall be established by rule and shall be adjusted no more often than once every two years. This fee schedule applies to all permits, regardless of date of issuance, and fees shall be assessed prospectively. Fees shall be established in amounts to recover expenses incurred by the department in processing permit applications and modifications, reviewing related plans and documents, monitoring, evaluating, conducting inspections, overseeing performance of delegated program elements, sampling or testing, and providing technical assistance and supporting overhead expenses that are directly related to these activities.
The annual fee paid by a permittee for any permit issued under this chapter shall be determined by the number of residences or residential equivalents contributing to the permittee's biosolids management system. If residences or residential equivalents cannot be determined or reasonably estimated, fees shall be based on other appropriate criteria.
The biosolids permit account is created in the state treasury. All receipts from fees under this section must be deposited into the account. Moneys in the account may be spent only after appropriation. Expenditures from the account may be used only for the purposes of administering permits under this chapter.
The department shall make available on the department's website information on fees collected, actual expenses incurred, and anticipated expenses for the current and following fiscal years.
The department shall work with the regulated community and local health departments to study the feasibility of modifying the fee schedule to support delegated local health departments and reduce local health department fees paid by biosolids permittees.
Before adopting or amending any rules relating to sampling or testing biosolids for PFAS chemicals, the department shall consult with an advisory committee of experts, interested parties, and other similar stakeholders, convened by the department. The purpose of consultation required under this section is to ensure that the department is soliciting and receiving sufficient input on requirements and standards for sampling or testing biosolids for PFAS chemicals.
For the purposes of this section, "biosolids" do not include septic tank sludge, also known as septage.
