Filed April 14, 2026 in the Northern District of Mississippi (No. 3:26-cv-00074-MPM-JMV) by the NAACP and the NAACP Mississippi State Conference. See NAACP v. xAI (Clean Air Act gas-turbine suit).
The allegation
The complaint opens on the industry's own slogan: "'Move fast and break things' is the unofficial motto of the tech industry. As the motto promises, artificial intelligence company Defendant X.AI Corp. and its subsidiaries broke Clean Air Act requirements that protect public health when rushing to build gas power plants for their 'Colossus' data centers in the greater Memphis area." It cites xAI's own marketing against it — the company "boasts on its website about the speed of construction 'outpacing every estimate'."
The operative factual allegation: "between August and December 2025, Defendants xAI and its wholly owned subsidiary MZX Tech LLC installed and began operating twenty-seven polluting gas turbines (the 'Colossus Gas Plant') in Southaven, Mississippi, which is in DeSoto County, without an air permit or regard for the health and safety of people living nearby."
The statutory theory is straightforward: "Congress specified that permits for new major pollution sources require implementation of the best available pollution controls," so operating without a permit also means operating without those controls.
The AI connection
The complaint states the chain explicitly rather than treating the data center as generic industry: "Defendants' Colossus Gas Plant powers xAI's nearby Colossus 2 data center, which in turn powers the chatbot 'Grok'." This makes it one of the clearest instances of AI compute demand producing a direct environmental-law claim. See AI Data Centers.
The environmental-justice framing
The affected population is characterized demographically: "Tens of thousands of people, including members of Plaintiffs NAACP and NAACP MS, live, worship, study and work in the homes, churches, and schools that immediately surround the Colossus Gas Plant, and hundreds of thousands more live in the greater Memphis area. A much larger share of this population is Black than that of the country's population as a whole."
The complaint frames this as a pattern rather than an isolated permitting lapse. "About a year ago, fewer than ten miles away from the Colossus Gas Plant… the nearby historically and majority Black community in Memphis's Boxtown neighborhood fought back against unpermitted air pollution from turbines powering xAI's Colossus 1 data center. Now xAI is planning a third data center ('Colossus 3') even closer to the Colossus Gas Plant."
The NAACP is described as "the nation's oldest and largest civil rights organization," founded 1909; the Mississippi State Conference asserts "an established history of environmental justice advocacy across Mississippi." Both plead status as a "person" under 42 U.S.C. §§ 7602(e) and 7604(a), the Clean Air Act citizen-suit provisions.
Relief sought
Declaratory and injunctive relief ordering xAI and MZX Tech to "cease operating the Colossus Gas Plant unless and until they obtain the required permits; to apply the necessary pollution controls; and to pay appropriate civil penalties for each day of violation." The complaint's stated stakes: absent an order, defendants "will continue to emit illegal air pollution… which will continue to harm members of the NAACP and NAACP MS."
