HB 5896 (Michigan, 2025-2026) – Summary
Purpose and main intent
- The bill aims to protect public health and the environment by strengthening testing and reporting requirements for sewage sludge (biosolids) and its derivatives used in land application.
- It expands PFAS (per- and polyfluoroalkyl substances) monitoring and creates mandatory testing, reporting, and permitting-related rules to limit PFAS concentrations in biosolids applied to land.
Key provisions and changes
1) Background and rulemaking authority (Sec. 3103)
- The Department of Environment, Great Lakes, and Energy (EGLE) shall continue to protect water resources and enforce environmental laws.
- The department may adopt rules to carry out its duties and may align with federal water pollution control requirements, while ensuring state funds are spent only as appropriated.
2) Land application of sewage sludge – PFAS testing and monitoring (Sec. 3131(1) and (2))
- By October 1, 1997, EGLE (in consultation with the Department of Agriculture and Rural Development) must promulgate rules to manage land application of sewage sludge and its derivatives.
- Rules must be at least as stringent as the federal minimums in 40 CFR Part 503, and may impose more stringent requirements to protect health and the environment.
- Monitoring: If a pollutant concentration in sludge exceeds levels from 40 CFR Part 503.13 Table 3, the monitoring frequency must be increased to at least double that in 40 CFR 503.16 Table 1 until concentrations fall to or below the Table 3 levels.
3) Recordkeeping and disclosure to local units (Sec. 3131(1))
- Sewage sludge generators or distributors must provide to a county, city, village, or township a copy of any record required under the rules for sludge or derivatives applied locally, free of charge and promptly after creation.
4) PFAS testing and reporting obligations (Sec. 3131(2))
- Operators who prepare biosolids and use them for land application must test the sludge for PFAS as directed by the department, before use.
- Test method: Use a multilaboratory-validated PFAS analysis method approved by the U.S. EPA, if available.
- Notification: The generator must inform landowners and farmers where the biosolids are applied of the PFAS concentration.
- Implementation: The department, with input from the Department of Agriculture and Rural Development, will promulgate rules under Michigan’s Administrative Procedures Act to implement these PFAS requirements.
5) Exemption and existing code sections (Sec. 3131(3)-(4))
- Certain exemptions apply to bulk biosolids or bulk derivatives that meet specified criteria, including being finished compost or stable/mature with minimal vector attraction, exceptional quality, and used in approved landscaping contexts (parks, athletic fields, cemeteries, nurseries, turf farms, golf courses, lawns, home gardens, or other director-approved sites).
- Recordkeeping for bulk exceptional-quality materials: If more than 20 cubic yards are sold or given away in a single transaction, the generator/distributor must maintain and provide a record to the department, including recipient details, quantity, and use.
Definitions (Sec. 3131(6))
- PFAS: Includes any member of fluorinated organic chemicals with at least one fully fluorinated carbon atom.
- Key terms (biosolids, bulk biosolids, derivative, exceptional quality, generator, residuals management program) align with Michigan administrative code definitions.
Affected parties and impacts
- Sewage treatment facilities, biosolids generators, and distributors: New PFAS testing requirements, reporting duties, and potential monitoring frequency increases.
- Landowners, farmers, and local units (counties, cities, villages, townships): Receiving records of sludge tests and PFAS concentration notices; potential changes in sludge acceptance/use due to PFAS limits.
- Environmental and public health regulators (EGLE and the Department of Agriculture and Rural Development): Expanded rulemaking authority, PFAS testing protocols, and compliance oversight.
Timeline and procedural notes
- Rulemaking provisions reference existing standards (40 CFR Part 503) and require action by October 1, 1997 for initial rules (although the bill’s 2026 introduction suggests modernization of those provisions within Michigan law).
- Future rules under the Administrative Procedures Act will be promulgated to implement PFAS testing and notification requirements.
- The bill is introduced and referred to the Committee on Government Operations; sponsor list includes multiple representatives and co-sponsors.
Overall impact
- Strengthens oversight of biosolids and sludge applied to land, with a clear focus on PFAS monitoring and transparency.
- Increases information flow to landowners and local governments.
- Potentially tighter controls on sludge use where PFAS levels are elevated, guiding safer land-application practices.
