On July 1, 2026, the U.S. Environmental Protection Agency (EPA) proposed a rule that would remove the current federal “minimum” public participation requirements for certain “minor” New Source Review (NSR) permits handled through State Implementation Plans (SIPs). If finalized, states and local air agencies would decide whether, when, and how long to provide public comment and hearing opportunities—so community experiences could vary more by location. EPA says the proposal would not change emission standards or weaken environmental protections.
