## EPA Tightens Rules on xAI's Generators The U.S. Environmental Protection Agency (EPA) now requires permits to operate gas turbine generators, even temporary ones. This closes a loophole in some local ordinances that waived this requirement for deployments lasting less than 364 days. This new regulation directly impacts xAI, Elon Musk's artificial intelligence company, which was using these generators to power its operations. The previous exemption, based on local ordinances, is no longer valid. ## General Context Power generation using gas turbine generators is often used in emergency situations or in areas with limited access to the power grid. However, such generators can have a significant environmental impact, which is why they are subject to strict regulations to limit polluting emissions.
