EPA Sharpens Air Permit Rules for Clarity

## Summary

The EPA is making it clearer which air pollution rules state and federal permits must follow, especially about new construction and accidental hazardous releases. This update affects businesses with operating permits and takes effect on October 26, 2026. It helps avoid confusion and keeps permit programs focused, with no new costs expected.

## Abstract

The U.S. Environmental Protection Agency (EPA) is updating the title V operating permit program regulations to codify the Agency's existing interpretations and policies concerning when and whether "applicable requirements" established in other Clean Air Act (CAA) programs may be reviewed, modified, and/or implemented through the title V operating permit program. Specifically, this final rule clarifies the limited situations in which requirements under the New Source Review (NSR) preconstruction permitting program would be reviewed using the EPA's title V oversight authorities. Additionally, this final rule clarifies that requirements related to an owner or operator's general duty to prevent accidental releases of hazardous substances are not "applicable requirements" for title V purposes and are, therefore, not implemented through title V.

- Regulatory Clarity with No New Costs: benefit, low. The rule, effective October 26, 2026, clarifies how "applicable requirements" from other Clean Air Act programs interact with title V permits, identifies limited situations where title V may address NSR or overlapping issues, and states that no new costs are expected from this final rule.
