The U.S. Environmental Protection Agency (EPA) has recently made a determination: the gas turbines employed by Musk's xAI at its 'Colossus' datacenter in Memphis, Tennessee, are required to adhere to the pertinent emission standards stipulated in the Clean Air Act. In the past, xAI took advantage of a regulatory oversight by designating the gas turbines as 'non-road engines.' This classification allowed them to sidestep the air pollution permit approval procedure. The EPA's fresh regulation unequivocally declares that such turbines can no longer be classified as non-road engines. Moreover, companies are now obligated to secure permits before installation, particularly when the combined emissions of these turbines are anticipated to surpass the 'major pollution source threshold.' This decision is widely regarded as a major triumph for local community activists. These activists have been vocally opposing the project for a long time, arguing that it significantly worsens air pollution in the adjacent neighborhoods.
