Abstract
(HB6066 · 103rd Legislature) Environmental protection: sewage; onsite wastewater treatment systems; regulate, and provide for assessments and evaluations. Amends secs. 12751, 12752, 12757 & 12771 of 1978 PA 368 (MCL 333.12751 et. seq.) & adds pt. 128. Latest action (2026-06-10): Bill Electronically Reproduced 06/09/2026
Why this matters
Michigan remains the only state without a statewide septic code, so parallel House and Senate vehicles (HB6066 and SB0771) signal a coordinated push to create uniform standards under a new Part 128 of the Public Health Code. For homeowners, this could mean mandatory point-of-sale or periodic septic inspections and potential remediation costs; for local health departments and municipalities, it would replace the current patchwork with baseline state requirements.
