DOJ Seeks to Dismiss NAACP Lawsuit Over Musks Mississippi Data-Center Turbines
The suit, lodged in April, accuses the company of operating dozens of natural‑gas turbines without the required permits to power a $20 billion data center in Southaven, Mississippi. The plaintiffs claim the turbines violate the Clean Air Act and threaten the health of nearby homes, schools and churches.
In the motion, presented to the federal court in Jackson, the DOJ argues that the turbines are essential for an AI system the company calls “Grok,” which the agency says is “critical to the economy” and the U.S. military. Associate Attorney General Stanley Woodward said the state of Mississippi—not the federal government—has the authority to issue air‑permit approvals and that the state had determined no permit was required. He added that the DOJ’s intervention is intended to protect national security and promote American energy and innovation.
The lawsuit alleges that xAI and its subsidiary MZX Tech installed nearly 50 portable gas turbines at the data‑center site without obtaining state air‑pollution permits, a requirement of the Clean Air Act. The NAACP’s complaint is filed under the Act’s citizen‑suit provision, which allows private parties to enforce federal environmental law. The plaintiffs argue that the lack of permits and controls on emissions endangers communities in North Mississippi and the Memphis area.
The Environmental Protection Agency (EPA) referred questions about the case to the DOJ, stating it is not a party to the dispute. Earthjustice, an environmental law firm representing the NAACP and the Southern Environmental Law Center, criticized the DOJ’s filing as an attempt to shield a wealthy tech company from accountability. “The DOJ wants to shield Elon Musk’s data‑center company from being held accountable for its illegal pollution,” said Earthjustice director Laura Thoms.
The DOJ’s intervention comes amid a broader Trump‑era policy shift that has emphasized artificial intelligence as a national security priority while rolling back environmental regulations. The administration has also supported Musk’s businesses financially, noting that SpaceX, Musk’s rocket company and parent of xAI, recently completed the largest initial public offering in history.
SpaceX has not responded to a request for comment. The company has previously stated it is in full compliance with the law and takes its environmental responsibilities seriously.
The NAACP’s director of environmental and climate justice, Abre’ Conner, said the Clean Air Act was designed to hold polluters accountable for harm to communities. Conner added that the organization will continue to challenge what it calls federal bullying and authoritarianism.
Legal experts note that the DOJ’s motion to intervene and dismiss the lawsuit is unprecedented. A professor of law at UCLA said the DOJ is attempting to undermine the citizen‑suit mechanism that has historically allowed private parties to enforce environmental statutes.
At present, the lawsuit remains pending. The DOJ’s motion will be considered by the federal court, and the outcome could determine whether the NAACP’s claims proceed to trial. The case also highlights the tension between rapid technological development and environmental regulation.
The next steps include the court’s decision on the DOJ’s motion, potential appeals, and any further filings by the parties. The outcome will have implications for how environmental law is applied to large data‑center projects and for the role of federal agencies in enforcing the Clean Air Act.
