This Michigan bill establishes the Data Center Water Regulation Act, which requires new and existing data centers to either use a closed-loop cooling system that recirculates water or source all water exclusively from municipal systems. Facilities that currently rely on groundwater or surface water must immediately stop operations once the law takes effect, while those violating the rules face civil fines of up to $1 million per day. The legislation also grants the Michigan Public Service Commission the authority to create specific rules for implementation and mandates that collected fines be deposited into the state's general fund.
