The proposed rule, which would apply to state plans under the Clean Air Act's minor New Source Review (NSR) program, would remove mandatory public participation requirements for minor industrial air pollution permits. Currently, federal rules require public notice and a comment period for such permits. Under the new proposal, state and local air quality authorities would decide whether and how to involve the public.
The Environmental Protection Network (EPN), which has submitted formal comments opposing the change, argues it would undermine transparency. "By eliminating the long-standing federal requirement for public notice, this proposal continues efforts by the current administration to turn its back on the fundamental EPA principle of transparency," said Mike Koerber, a former deputy director of the EPA's Office of Air Quality Planning and Standards.
EPA Administrator Lee Zeldin has stated that the Trump administration will not set national environmental rules for the datacenter industry, arguing that state and local governments are better equipped due to differing local conditions such as water availability, air quality, and electricity needs. However, the EPN says the proposed rule contradicts Zeldin's earlier transparency memorandum, which pledged "the fullest possible public participation in our decision making."
The datacenter boom, driven by the AI gold rush, has led many operators to install on-site gas-turbine generators to bypass grid connection delays. These generators emit nitrogen oxides (NOx) and other pollutants linked to smog and health problems. Without public notice, communities may lose the ability to weigh in on such facilities.
Public opposition to datacenter construction is high; a recent Gallup survey found over 70 percent of Americans oppose having such a facility in their neighborhood. President Trump has voiced support for datacenters, recently praising their economic benefits and warning against regulatory delays.
The EPA has not yet responded to a request for comment on the proposed rule. The EPN notes that without mandatory public review, some facilities may avoid major-source pollution controls entirely by being classified as minor or synthetic-minor sources.
