AI firms want more data centers; Trump's EPA may give neighbors less say

The Trump administration is considering a rule change that would let states decide how the public participates in air pollution permitting for new sources, potentially reducing community notice for data center power plants. The Environmental Protection Agency held a hearing on the proposal Wednesday as data centers face growing local opposition, with Vanessa Lynch of Moms Clean Air Force stating, "People want to have a say.

The Trump administration is quietly considering a rule change that could make it easier for polluters to build facilities—including certain gas plants https://www.wired.com/story/new-gas-powered-data-centers-could-emit-more-greenhouse-gases-than-entire-nations/ and diesel generators that power data centers https://www.wired.com/story/data-centers-are-driving-a-us-gas-boom/ —with little to no notice to the public. On Wednesday, the Environmental Protection Agency held a public hearing on a proposed rule change that would hand the power to states to decide how the public participates in the permitting process for certain new sources of air pollution https://www.wired.com/story/one-in-three-americans-live-in-areas-with-dangerous-air-pollution/ . The proposed rollback comes as data centers face greater pushback https://www.wired.com/story/the-data-center-resistance-has-arrived/ across the US, with many communities using the permitting process to try to slow down development https://www.wired.com/story/anti-data-center-movement-reshaping-michigan-politics/ . Any changes could have major consequences for how ordinary people are given notice about new or expanded polluting facilities coming into their neighborhoods. “As someone actively working in communities with data centers, I know this to be fundamentally true: People want to have a say,” Vanessa Lynch, a Pennsylvania organizer with Moms Clean Air Force, said at the EPA hearing. Companies building any kind of facilities that release air pollution are required to get permits under the Clean Air Act. Polluting sources can either be put through a “major” permitting process, meaning that they meet or exceed thresholds for certain pollutants, or a “minor” one for those that don’t. Major sources of pollution are reviewed by both federal and state regulators and have extensive requirements before and after construction. However, there’s less oversight of minor sources. The scope of what gets permitted as a minor source is extremely broad and can include everything from dry cleaners and auto body shops to to diesel and gas engines. The latter two are increasingly being used to power data centers, with operators such as xAI https://www.wired.com/story/spacex-ipo-how-people-living-near-xai-data-centers-feel/ and Meta using minor source permitting processes to build behind-the-meter gas plants.
