Why did the U.S. Department of Justice intervene in the lawsuit against xAI’s unpermitted gas turbines in Mississippi?

The U.S. Department of Justice sought to join the lawsuit citing national security reasons for allowing the unpermitted gas turbines—57 in total—to power xAI’s data center complex in Memphis, arguing that federal enforcement discretion permits bypassing local air permit requirements when aligned with broader national interests; the DOJ contends that if the federal government chooses not to enforce environmental laws in such cases, local communities cannot sue over resulting pollution.

What is the core legal and environmental concern raised by experts regarding the DOJ’s intervention in this case?

Experts, including former top EPA enforcement official David Uhlmann, warn that the DOJ’s position represents an 'unprecedented attack on the Clean Air Act' because it seeks to eliminate citizen suit rights—the law’s 'fail safe' mechanism allowing public enforcement when the government fails to act—thereby enabling any administration to shield favored industries or projects from accountability regardless of pollution impacts on public health.
