What it does

Summary by the , the Legislature's nonpartisan drafting office. It's their wording, not ours.

Current law requires the Department of Natural Resources (DNR) to administer a safe drinking water program and to establish all safeguards that DNR determines to be necessary in protecting public health from impure drinking water supplies. DNR has promulgated a rule that requires municipal drinking water systems to provide continuous disinfection of the water that they provide, beginning no later than December 1, 2013.

This bill prohibits DNR from requiring a municipal water system to provide continuous disinfection of the water that it provides, unless continuous disinfection is required under federal law.
