Elon Musk's xAI has installed 59 unpermitted natural gas turbines to power its Colossus 2 data center near Memphis, roughly double what the company publicly disclosed, without obtaining required federal Clean Air Act permits. Emissions from these turbines — including nitrogen oxides, soot, and formaldehyde — are disproportionately affecting predominantly Black neighborhoods in the area, triggering NAACP litigation and a Department of Justice intervention citing national security concerns over the Grok AI system. The pollution violations raise both environmental justice and regulatory accountability questions that will likely extend into 2027 as lawsuits proceed.
