EPA Proposes Pre-Permit Construction Rule to Boost AI Infrastructure

The U.S. Environmental Protection Agency proposed a rule on May 12, 2026, allowing data centers, gas-fired power plants, and factories to begin constructing non-polluting components before receiving federal New Source Review air emission permits. Non-emitting components covered under the proposal include piping, wiring, cement pads, support structures, and site preparation activities such as clearing vegetation and excavating land. Construction on components that emit pollutants remains prohibited until permits are issued, and companies undertake early work at their own economic risk. EPA Administrator Lee Zeldin announced the proposal, stating it aims to streamline critical American infrastructure and advance technological development, specifically to support the AI race against China. The changes will undergo a 45-day public comment period. Separately, EPA air chief Aaron Szabo issued guidance to accelerate Title V permit approvals by allowing the agency's review to occur concurrently with the public comment period, reducing overall project approval timelines. President Donald Trump issued an executive order to revoke guardrails slowing AI development, providing the broader policy context for the EPA actions. Environmental advocates strongly opposed the proposal. Attorneys from Earthjustice and the Southern Environmental Law Center argued the move undermines the Clean Air Act by creating sunk costs that make it politically difficult for regulators to reject permits based on air quality concerns.
