> A federal judge in Mississippi refused to dismiss the Clean Air Act case over turbines that power xAI’s Colossus 2 data centre. The ruling does not decide whether the company broke the law.

A lawsuit over the gas turbines that power one of xAI’s data centres can go ahead. In a ruling reported on 31 October, US District Judge Debra M. Brown denied a motion by xAI, the AI company now owned by SpaceX, to dismiss a Clean Air Act case brought by the NAACP, TechCrunch reported.

## The case

The NAACP, represented by the Southern Environmental Law Center, sued in April over turbines in Southaven, Mississippi, which supply power to xAI’s Colossus 2 data centre across the state line in Memphis. It alleges that xAI installed and ran at least 35 combustion turbines without the required air permits, and asks the court to stop them running until they go through permitting, as well as for civil penalties.

xAI argued that the turbines were mobile and so exempt from permits, and that the NAACP had no standing to sue. The judge disagreed on both counts at this stage. She found that the turbines are not “mobile sources” under Mississippi’s air quality plan, and rejected the argument that citizen lawsuits under the Clean Air Act are unconstitutional, writing that such plaintiffs “are not exercising the federal government’s executive power.” Earlier in October, the court also turned down a Justice Department motion to dismiss the case.

## What the ruling means

The decision is procedural. It lets the case go ahead but does not find that xAI violated the law. Abre’ Conner, the NAACP’s director of environmental and climate justice, called the ruling “another important victory in our effort to hold xAI accountable,” adding: “xAI cannot operate gas turbines without the required permits.” TechCrunch said SpaceX had not responded to a request for comment.

The case is one of the clearest tests of how pollution law applies to the private power plants that AI companies are building to get electricity faster than the grid can provide it. Data centres’ demands on power and water may also be a factor in this autumn’s US midterm elections.
