Judge allows NAACP Clean Air Act lawsuit against xAI over Colossus data center to proceed
A federal judge denied xAI's motion to dismiss an NAACP suit alleging the company operated at least 35 combustion turbines and other pollution sources at the Colossus data center outside Memphis without required preconstruction or operating air permits, violating the Clean Air Act. Judge Debra M. Brown found the plaintiffs have statutory standing, the turbines are not 'mobile sources' under Mississippi's State Implementation Plan, and constitutional challenges fail, so the case will proceed (a similar DOJ motion was also denied earlier).
