The U.S. District Court for the Northern District of Mississippi 10 30 denied xAI's motion to dismiss. The NAACP, represented by the Southern Environmental Law Center (SELC) and Earthjustice, alleges that xAI operated gas turbines at a power plant supplying electricity to its Colossus 2 data center in Southaven, Mississippi, without obtaining construction and operating air permits, thereby violating the Clean Air Act. xAI argued that these turbines qualify as "mobile sources" exempt from permitting, that the plaintiffs lack standing, and that the citizen suit provision is unconstitutional; Judge Debra M. Brown rejected all these arguments. A similar motion to dismiss previously filed by the Department of Justice was also denied this month.
Confidence: High (85) · Event Date 2026-10-30
Reasoning
- Using gas turbines directly next to data centers to meet construction deadlines is a common practice. This ruling clarifies that such "temporary" turbines also require air permits, sending a precedent-setting signal to other AI data centers built in this manner. The plaintiffs claim these turbines can emit more than 5000 tons of nitrogen oxides annually.
- According to TechCrunch, public opinion on data centers in the U.S. has shifted noticeably: New York State recently passed a moratorium on new data centers, and Amazon and Microsoft have pledged to stop signing non-disclosure agreements when dealing with government agencies, with midterm elections approaching.
Usage
- None.
Risks
- This is merely a procedural ruling; the merits of the case have not yet been decided. The court has not yet ruled on the plaintiffs' motion for a preliminary injunction.
- The number of turbines and emission figures are claims made by the plaintiffs. SpaceX, to which xAI belongs, did not respond to TechCrunch's request for comment. The editors did not read the original court opinion, relying instead on a press release from the plaintiffs' counsel, SELC (which quoted the ruling), and TechCrunch's reporting.
