Abstract
(SB0771 · 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 (2026-06-17): Placed On Order Of Third Reading With Substitute (s-2)
Why this matters
Michigan is currently the only U.S. state without a uniform statewide code governing onsite wastewater treatment (septic) systems, leaving assessment and inspection standards to individual county health departments. SB0771’s proposed Part 128 would create statewide assessment and evaluation requirements — a significant shift for homeowners, real-estate transactions, local health departments, and surface-water quality across the state.
