Environmental protection: sewage; onsite wastewater treatment systems; regulate, and provide for assessments and evaluations. Amends sec. 12752 of 1978 PA 368 (MCL 333.12752) & adds pt. 128.

This bill updates Michigan's public health code to strengthen the regulation of onsite wastewater treatment systems, such as septic tanks, for properties not connected to public sewer lines. It establishes new definitions for various waste systems and grants local health departments expanded authority to inspect, evaluate, and enforce compliance with these regulations. The legislation also clarifies that connecting to an available public sewer system is a priority for public health and safety.
