New EPA rules mean polluting US data centers can now keep their output secret from neighbors
EPA wants states to control public notice for minor pollution permits as data center construction expands and community concerns increase.
The United States Environmental Protection Agency (EPA) is proposing changes to its rules regarding pollution permits for data centers, which could grant state and local authorities the power to decide whether residents receive notice of new pollution sources. Currently, the Clean Air Act requires federal disclosure and public comment periods for minor industrial air permits.
If implemented, the proposed rule would make these requirements optional for states, potentially allowing data centers with gas turbines to operate without public scrutiny, even near residential areas. Mike Koerber, a former EPA deputy director, expressed concern that the proposal undermines the agency's commitment to transparency.
The Environmental Protection Network, comprised of former EPA employees, has also formally objected to the change. Data center construction is rapidly expanding in the U.S., particularly due to artificial intelligence development, and often relies on on-site gas turbines for power. These turbines can emit pollutants like nitrogen oxides, prompting concerns among nearby residents.
Despite public opposition to data centers near their homes, the Trump administration has continued to support the industry's expansion, citing its economic benefits.
