The Trump administration is exempting power plants serving artificial intelligence data centers from Clean Air Act acid rain rules and moving to roll back public participation in minor air permit applications. The actions coincide with New York enacting a moratorium and Palm Beach County rejecting a major campus expansion.
Exemptions From Acid Rain Regulations for Dedicated Power Plants
The federal government is lifting specific pollution limits for power facilities that supply electricity exclusively to artificial intelligence infrastructure. According to reporting, power plants built to serve data centers rather than human communities will no longer need to participate in the Clean Air Act’s Acid Rain Program. These facilities escape requirements to cut emissions of sulfur dioxide and nitrogen oxides. Nearly 60 of these islanded power plants are currently operating or under construction nationwide after receiving federal fast-tracking.
Administration officials defended the policy shift as essential for technological infrastructure.
“Ensuring that the United States maintains our artificial intelligence dominance is essential to national security and economic prosperity,”
Aaron Szabo, EPA Assistant Administrator for Air and Radiation
He added that the agency is proud to further the President’s agenda through commonsense approaches to regulating
as projected energy demands climb. Bloomberg estimates that data centers will drive 20 percent of the nation’s total energy consumption within the next eight years.
Environmental researchers note that precursor gases tied to acid rain strip soil nutrients, damage vegetation, and degrade water systems. Furthermore, human exposure to these emissions can exacerbate cardiac and respiratory conditions, causing symptoms ranging from coughing and shortness of breath to eye irritation.
Proposed Rollbacks on Public Notice for Minor Air Permits
Parallel to the acid rain exemptions, the Environmental Protection Agency held a public hearing regarding a proposed rule change that would shift oversight of public participation in minor air pollution permits directly to state authorities. The adjustment affects minor sources like diesel generators and gas turbines increasingly used behind the meter by operators such as Meta and xAI.
Under current federal rules, the Clean Air Act mandates public involvement steps for major pollution sources alongside baseline requirements for minor permits. The new guidance would put state and local agencies most familiar with local issues in the driver’s seat to determine whether, when, and for how long to provide opportunities for public participation for proposed new minor sources and modifications
, according to an EPA spokesperson who emphasized that underlying emissions standards remain unchanged.
Community advocates and legal experts warn the change could shut residents out of upcoming infrastructure reviews. Vanessa Lynch, an organizer with Moms Clean Air Force in Pennsylvania, testified at the EPA hearing that People want to have a say
, pointing to Georgia as a jurisdiction where public engagement is already a concern. Keri Powell, an attorney with the Southern Environmental Law Center, noted that legal groups rely on existing public notice frameworks to review facility applications early in the development cycle.
State-Level Moratoriums and Palm Beach County Pushback
While federal regulators ease restrictions, local and state authorities are pushing in the opposite direction. New York Governor Kathy Hochul instituted a one-year temporary moratorium on building new large-scale data centers consuming 50 megawatts or more. The pause directs the Department of Environmental Conservation to halt discretionary permits while officials complete a Generic Environmental Impact Statement examining energy demands, water usage, and air quality.
President Donald Trump criticized the New York pause on Truth Social, describing data centers as cash cows
and calling the moratorium a terrible decision. Governor Hochul’s office defended the action through social media, stating that communities powering artificial intelligence deserve to share in its success.
Conflict over data center expansion also played out in Florida. Commissioners in Palm Beach County voted 5-1 to reject an expansion proposal for Project Tango, a hyperscale artificial intelligence campus near Arden. The denial followed more than 12 hours of public debate involving hundreds of residents and local stakeholders raising concerns regarding noise, vibration, and water utilization.
Project spokesperson Ernie Cox expressed disappointment in the outcome.
“We are disappointed with the Commission’s decision. We reconfirmed our commitment to all conditions asked of us associated with our request and we addressed concerns through in-depth technical studies and analysis. We remain committed to helping meet the region’s growing critical infrastructure needs and will be taking time to evaluate our options moving forward.”

Because commissioners denied the application without prejudice, developers retain the option to revise their plans and resubmit them for future consideration.
