EPA Proposes Air Pollution Exemption “Deal” for Data Centers in Georgia

The EPA has proposed a rule that would remove public notice and comment requirements for air pollution permits issued to "minor sources," a category that covers most data centers and the large diesel generators they use for backup power. Under current rules, these permits allow some public input. The new proposal would cut that out entirely, meaning neighbors would no longer have a formal way to learn about or challenge new generator installations near their homes.

This matters most right now in Georgia, where data centers have been expanding quickly and often rely on fleets of diesel generators for backup power. The Sierra Club has spent nearly two years pushing Georgia's environmental regulators for more transparency on how many generators are running at these sites and what their combined pollution adds up to. The group argues the EPA's proposal would weaken one of the few tools residents have to push back on these facilities, since data centers are often permitted piecemeal in ways that can obscure their total air quality impact.

If you live near a data center or one is being proposed in your area, this rule change could affect whether you get any advance notice or chance to comment before new generators go in. The EPA has scheduled a public hearing on the proposal for July 22, and written comments are being accepted through August 21, 2026.
