MI HB4985

Amends the Safe Drinking Water Act definition of "public water supply" to exempt agricultural waterworks systems that provide water solely for agricultural purposes and are not intended for human consumption.

Agricultural waterworks systems are exempt from regulation if they are tested annually (or according to the Manufacturing Milk Law of 2001 if applicable) and meet chemical, physical, and biological standards required under that law.

Changes the definition of "community supply" by replacing "which" with "that" in the statutory language describing public water supplies serving at least 15 living units or 25 residents on a year-round basis.

Changes the definition of "public water supply" by replacing "either" with "any of" to clarify the exclusions that apply to systems serving only 1 living unit, systems consisting solely of customer site piping, and the newly exempted agricultural systems.

Takes effect 90 days after enactment.
