A federal judge has allowed the NAACP’s lawsuit over pollution from xAI’s data center to proceed. The case accuses Elon Musk’s AI company of operating gas turbines without required environmental permits near Memphis, Tennessee.
U.S. District Judge Debra M. Brown rejected xAI’s motion to dismiss on October 30. The dispute concerns a gas-fired power plant in Southaven, Mississippi, supplying electricity to the company’s Colossus 2 data center.
Judge Rejects xAI’s Arguments Over Gas Turbine Permits.
The NAACP alleges that xAI installed and operated at least 35 combustion turbines and other pollution sources without required permits. The lawsuit claims the company violated the federal Clean Air Act and Mississippi’s environmental regulations.
xAI argued that its turbines qualify as mobile equipment and are therefore exempt from certain permitting requirements. It also challenged the NAACP’s legal standing and the constitutionality of citizen enforcement lawsuits.
In her 28-page court ruling, Brown rejected those arguments. She determined that the turbines do not qualify for the mobile-source exemption under Mississippi’s federally approved air pollution rules.
The judge also upheld the NAACP’s right to bring the lawsuit. She found that the Clean Air Act’s citizen enforcement provisions do not improperly transfer executive authority to private organizations.
The decision allows the lawsuit to continue but does not establish that xAI violated environmental law. The underlying pollution allegations remain subject to further proceedings.
NAACP Welcomes Ruling as Environmental Dispute Continues
NAACP environmental and climate justice director Abre’ Conner called the decision another important victory in efforts to hold xAI accountable. In an Earthjustice statement, environmental advocates said nearby communities deserve protection from potentially harmful emissions.
The ruling follows an earlier setback for the U.S. Department of Justice. On October 20, the court rejected the department’s attempt to block the NAACP’s lawsuit.
The Justice Department had previously supported xAI’s position, citing national and energy security concerns. TechAmerica.ai earlier reported on the federal government’s arguments and the ongoing dispute over turbine permits.
SpaceX has also outlined plans to replace the disputed equipment with permanent power infrastructure. Its previously announced turbine removal schedule extends into July 2027.
Data Center Expansion Faces Growing Public Opposition
The legal fight comes amid broader concerns about electricity consumption, air pollution and other effects of AI infrastructure projects.
According to Reuters, voters in 10 states will consider data center-related measures in the November 3 elections. The proposals include restrictions, construction delays and additional requirements for new facilities.
For xAI, the immediate issue remains whether its Mississippi power plant complies with environmental regulations. The court has not yet ruled on the NAACP’s request for a preliminary injunction, which could affect continued turbine operations.
