There are no exceptions that would allow this major source of air pollution to evade the law, and citizens have the right to defend themselves in Court against illegal pollution

On Friday, the U.S. District Court for the Northern District of Mississippi denied xAI's motion to dismiss a Clean Air Act lawsuit brought against the company by the NAACP. The lawsuit seeks to hold the tech company accountable for its continued operation of an illegal, unpermitted power plant that supports its Colossus 2 data center. The ruling comes shortly after the Court denied a similar motion from the U.S. Department of Justice.
"This decision is another important victory in our effort to hold xAI accountable. The courts have repeatedly rejected attempts by xAI and the DOJ to dismiss the NAACP's Clean Air Act case, affirming our right to pursue justice for communities impacted by pollution. Our position has been clear: xAI cannot operate gas turbines without the required permits. Now that the motion to dismiss has been denied, we look forward to continuing to defend our position in court," Abre' Conner, NAACP Director of Environmental and Climate Justice said.
In its motion to dismiss, xAI claimed that citizen suits-which give communities the right to defend themselves from unlawful pollution-were unconstitutional. The court rejected this argument, finding that "because citizen suit plaintiffs sue on their own behalf, in their own name, and seek penalties that redress harm to themselves, they are not exercising the federal government's executive power."
The tech company also argued that the dozens of unpermitted gas turbines running at its illegal power plant were somehow exempt from the Clean Air Act. The Court rejected this argument, making it clear that methane gas turbines, even so-called 'temporary' turbines, are subject to the Clean Air Act and require air permits. The Court held that "because the Plant is not a 'mobile source' according to the federal regulations…the Plant was not (and is not) exempted from permitting requirements under the Clean Air Act."
"The Clean Air Act promises that communities that have been failed by federal, state, and local leaders have the right to go to court to protect themselves from illegal pollution, and this ruling makes it clear that this right cannot be tossed aside simply because a massive corporation finds it inconvenient," Kym Meyer, Litigation Director for the Southern Environmental Law Center said. "This decision is a victory for communities across the nation, but especially for those in South Memphis and North Mississippi that have been forced to breathe the unlawful air pollution being spewed from xAI's unpermitted power plant. We will continue to fight to hold the tech company accountable in court."
"There is no massive loophole in the Clean Air Act that will allow Elon Musk's company, xAI, to avoid accountability for illegally pumping pollution into its neighbors' backyards," said Laura Thoms, Director of Enforcement for Earthjustice. "We're glad the judge will move forward with this case so we can continue to pursue the relief the surrounding communities so desperately need."
xAI's gigantic, unpermitted power plant in Southaven, Mississippi is one of the largest sources of air pollution in the region-illegally pumping out tons of pollution. These gas turbines can emit more than 5,000 tons of smog-forming nitrogen oxides (NOx), 400 tons of fine particulate matter, and 47 tons of formaldehyde each year. These harmful pollutants are tied to increases in asthma, heart disease, respiratory illnesses, cancer, and premature death.
The NAACP is represented by the Southern Environmental Law Center and Earthjustice in this case. The Court has yet to rule on NAACP's motion for a preliminary injunction.
