No AI Data Centers on Federal Lands Act
Latest action (23 Jul 2026): Introduced
What this bill does
H.R. 9939, the "No AI Data Centers on Federal Lands Act," would prohibit the construction or operation of artificial intelligence data centers, as well as related infrastructure such as transmission lines, power substations, natural gas facilities, and water/cooling systems, on federal land. The bill defines an AI data center broadly to include facilities used for developing or operating AI models at scale, or those exceeding certain power-capacity thresholds. Federal land is defined to cover land owned or managed by the United States, including Department of Defense land, but excludes land held in trust for Indian Tribes.
The bill would require any federal agency currently operating, leasing, constructing, or planning such facilities to halt operations or construction within 30 days of enactment and begin removing the data centers and associated infrastructure. Removal and site restoration would have to follow existing environmental cleanup law (CERCLA). The measure would primarily affect federal agencies and any private companies leasing federal land for AI data center operations, requiring them to cease activity and dismantle existing facilities.
The bill was introduced on July 23, 2026, by Rep. Rashida Tlaib and referred to the House Committee on Natural Resources. It has not yet received a committee vote, floor action, or further congressional consideration.
