House Bill 6066 of 2026

Summary

House Bill 6066 would substantially revise Michigan’s Public Health Code to create a new statewide framework for onsite wastewater treatment systems, including septic systems, alternative systems, holding tanks, outhouses, and related greywater systems. The bill adds a new Part 128 and amends existing sections to define key terms, establish statewide standards, and shift more of the regulation of non-sewered properties into a uniform state/local permitting and inspection structure. It authorizes local health departments to administer conventional and alternative system programs under state rules, while the Department of Environment, Great Lakes, and Energy (EGLE) retains ultimate authority and must promulgate a statewide sewage code within three years. The bill requires permits for installation, alteration, repair, and replacement of onsite wastewater systems, and it conditions building permits and certificates of occupancy on health department approvals. It also creates a registration system for proprietary wastewater products and a registration system for evaluators who inspect systems and prepare reports. The legislation establishes mandatory evaluation schedules for properties not connected to public sanitary sewers, with more frequent review for older systems and systems near surface water or sensitive areas, and it requires corrective action when failures are identified. It further creates an onsite wastewater treatment system administration fund and a public education and training fund, financed by application fees, administrative fees, civil fines, and other revenue sources. The bill’s impact on state law would be significant: it would replace or supersede existing administrative rules governing outhouses and onsite wastewater systems with a statewide sewage code, expand inspection and enforcement authority, and create new civil and criminal penalties for noncompliance or false reporting. It also gives local health departments new responsibilities for plan development, permitting, inspections, evaluations, recordkeeping, and enforcement, while authorizing grants and loans for low-income homeowners to help pay for evaluations and repairs. In addition, it limits local point-of-sale ordinances by requiring them to be consistent with or at least as stringent as the new state standards and by prohibiting them from blocking property transfers. Because no committee transcripts or recorded votes were provided, the bill’s sentiment can only be inferred from its structure and policy design. Overall, the bill appears to reflect a public-health and water-quality oriented approach, with strong emphasis on system maintenance, inspection, and long-term oversight. At the same time, it includes fee waivers, funding assistance, phased implementation timelines, and grandfathering provisions for some existing systems, suggesting an effort to balance regulatory tightening with implementation flexibility and homeowner affordability. The main points of contention likely concern the scope and cost of the new mandates, especially the required evaluations, fees, registration requirements, and potential fines and liens for noncompliance. Property owners, local governments, evaluators, installers, and manufacturers may differ over the burden of statewide standards, the treatment of proprietary technologies, and the extent to which local ordinances should be preempted or constrained. Another likely issue is the bill’s broad enforcement authority and the requirement that owners of older or rural systems undergo periodic inspections, which could be viewed as necessary environmental protection by supporters and as an administrative and financial burden by critics.

Impact

HB6066 would amend Michigan’s Public Health Code to create a comprehensive statewide regulatory system for onsite wastewater treatment systems, including septic systems, alternative systems, greywater systems, holding tanks, and outhouses. It would establish new permitting, inspection, evaluation, registration, reporting, and enforcement requirements; create new state funds; and require EGLE to promulgate a statewide sewage code that governs local health department administration. The bill would also affect building permit and occupancy approval processes, local point-of-sale ordinances, and the authority of local health departments and the department over onsite wastewater regulation.

Sentiment

No committee testimony or vote record was provided, so there is no direct evidence of legislative support or opposition in the supplied materials. Based on the bill text, the measure is framed as a public health and water quality protection bill, with a generally regulatory and preventative orientation. Its inclusion of phased implementation, fee waivers for lower-income owners, and grant/loan support suggests an attempt to make the policy more acceptable to affected property owners and local agencies.

Contention

Likely areas of contention include the cost and frequency of mandatory evaluations, the new fees and fines, the potential for recorded liens on property, and the administrative burden placed on homeowners and local health departments. Stakeholders may also disagree over state preemption of local ordinances, the regulation of proprietary wastewater products, and whether the bill gives too much discretion to EGLE and local health departments. Rural property owners, septic system owners, local governments, installers, evaluators, and product manufacturers are the most likely groups to hold differing views.
