Overview
- On Monday the Department of Justice filed to intervene in the NAACP’s April lawsuit and asked a federal judge to dismiss the case on the grounds that halting xAI’s turbines would threaten national security.
- DOJ filings and a Department of Defense declaration say xAI’s Grok model runs on Secret and Top‑Secret networks and was used to support recent military strikes, which the government says makes continuous power to Colossus sites essential.
- Plaintiffs and environmental groups say emails show turbine counts at Colossus 2 rose from about 27 to roughly 57 by mid‑May and that that expansion sharply increased NOx, PM2.5 and formaldehyde emissions that harm nearby mostly Black communities.
- xAI and some state regulators contend the trailer‑mounted turbines qualify for a temporary mobile exemption that delays permitting, while the EPA and plaintiffs argue many units are effectively stationary and must meet Clean Air Act rules.
- The case now raises legal and policy stakes for how courts treat citizen enforcement of pollution laws when the federal government claims enforcement priority on national‑security grounds and could set a template for other AI and cloud operators.
