The Trump administration has intervened in an environmental lawsuit against Elon Musk’s xAI, asking a federal court to dismiss a case brought by the NAACP over illegal air pollution from natural gas turbines powering the $20 billion Colossus 2 data centre in Memphis, Tennessee. The move has drawn attention from Texas business and legal observers watching the intersection of AI infrastructure, environmental regulation, and federal power.
The Justice Department’s Argument
In a motion filed on Monday, the Department of Justice claimed the NAACP’s lawsuit threatens “national, economic, and energy security” by seeking to shut off the power supply for AI systems that support the Department of War’s military operations. The Pentagon’s top AI official, Cameron Stanley, said in a sworn declaration that xAI’s Grok model was used to launch more than 2,000 munitions at 2,000 targets within the first 96 hours of the US-Israel war on Iran, as Al Jazeera reported. The DOJ also argued that the Constitution vests the power to seek civil penalties “conclusively and preclusively” in the executive branch.
Environmental and Legal Pushback
The NAACP alleges xAI built dozens of natural gas turbines without the necessary permits, exposing predominantly Black communities to harmful pollutants linked to asthma, respiratory diseases, heart problems, and certain cancers. Earthjustice, representing the NAACP, called the intervention a “massive power grab” by the Trump administration. UCLA environmental law professor Ann Carlson described it as a “brazen attempt” to limit enforcement of the Clean Air Act, telling Al Jazeera it would let “polluters off the hook even for blatant violations of the law.”
Implications for Texas Data Centres
Texas has become a major hub for data centre construction, attracted by cheap land, abundant energy, and deregulated electricity markets. The xAI case could set a precedent for how environmental regulations apply to AI infrastructure nationwide. If the federal government succeeds in blocking citizen lawsuits on national security grounds, it could accelerate permitting for Texas data centres — but also reduce community recourse against pollution from the massive power demands of AI compute clusters. The case is being closely watched by both the Texas tech industry and environmental groups across the state as a potential bellwether for the balance between national security imperatives and local environmental protections. The Texas Commission on Environmental Quality has been reviewing its own permitting processes for data centre power generation, with several large projects in the Dallas-Fort Worth and Austin areas seeking expedited approvals. The outcome of the xAI case could influence how Texas regulators balance economic development with environmental compliance.
