The Trump administration’s EPA wants to eliminate a federal requirement that has forced industrial polluters to notify the public before receiving air permits — a move that would let data center developers break ground without neighbors ever knowing until the bulldozers arrive. The proposal targets New Source Review, a permitting framework that’s been on the books since the 1970s and covers everything from landfills to power plant expansions. Under the plan, states and local air agencies would decide whether to notify residents about so-called “minor” pollution sources, a label advocates say is dangerously misleading.
Keri Powell, senior attorney at the Southern Environmental Law Center, didn’t mince words about the timing. “You can see why that would be so interesting to an administration that wants to rush through the construction of data centers,” she said, describing a future where permits are “issued in secret behind closed doors.” She’s not wrong about the stakes. The generative AI boom has turned data centers into a permitting flashpoint, with communities pushing back on everything from diesel generator emissions to the power plants built to feed them. xAI’s Colossus facility in Tennessee — billed as the “most powerful AI training system yet” — applied for a minor source permit just last year, triggering a hearing and thousands of public comments.
EPA administrator Lee Zeldin framed the change as cutting “unnecessary and burdensome red tape,” arguing that local authorities should handle permitting decisions. But air pollution doesn’t respect state lines, which is exactly why federal oversight existed in the first place. Nearly 200 health and environmental groups filed comments opposing the proposal before last week’s deadline, including the SELC and NAACP, which also threatened to sue xAI over unpermitted gas turbines at its Tennessee site. Kentucky Resources Council Senior Attorney Byron Gary argued that stripping public comment would deprive agencies of “lived experience data” from communities already dealing with cumulative pollution burdens.
The public comment period closed with more than 4,900 submissions, and the EPA says it’s still reviewing them before finalizing the rule. That’s a lot of pushback for a proposal dressed up as administrative streamlining. The real question is whether the agency will actually weigh those voices — or whether the bulldozers show up first.
