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.

This bill updates Michigan's Public Health Code to strengthen regulations and oversight of onsite wastewater treatment systems, such as septic tanks and holding tanks, primarily affecting property owners and local health departments. It establishes new definitions for various waste treatment systems and grants the Department of Environment, Great Lakes, and Energy, along with local health departments, expanded authority to inspect, evaluate, and investigate these facilities on private property. To support compliance and public safety, the legislation creates a dedicated public education and training fund financed by a $5 fee added to application charges, which will be used to fund outreach programs and training for health officials and evaluators.
