AB 2469: Data centers: water use disclosures.
The bill aims to regulate data center construction and expansion by requiring cities, counties, and city-counties to consider water scarcity and supply when approving permits. To be approved, a data center must provide detailed information on its water use, including a water scarcity plan, supply assessment, and use assessment. The bill also prohibits data center construction within certain groundwater basins and requires the applicant to cover the cost of necessary water infrastructure improvements. Additionally, the bill would establish a new classification system for large consumptive use facilities, including data centers, to track their water use. This classification would be separate from existing CII water use classifications.
