Summary

Highlight any text to annotate
This bill prohibits the construction and operation of artificial intelligence data centers on all federal lands, including those managed by the Department of Defense, while explicitly excluding tribal lands. Any federal agency currently operating, leasing, or constructing an AI data center must cease operations and begin removing the facility and its associated infrastructure within 30 days of the law's enactment. The bill defines AI data centers broadly to include facilities with over 20 megawatts of power capacity or those using advanced cooling systems, along with all supporting infrastructure like power lines and water pipelines. The removal process must comply with environmental cleanup standards under the Comprehensive Environmental Response, Compensation, and Liability Act, ensuring sites are properly remediated after the data centers are demolished or deconstructed. The legislation does not authorize specific funding and establishes an immediate 30-day deadline for agencies to begin the removal process.
