## Summary

**Limit New Source Review triggers to real, measurable emission rate increases.** This bill would change the Clean Air Act to redefine when a physical change at a stationary source counts as a "modification" or "construction". It ties modification to an increase in the maximum hourly emission rate above the highest hour in the prior 10-year period and narrows prevention of significant deterioration (PSD) and nonattainment permit triggers to physical changes to discrete parts of an emissions unit, while adding exceptions for reliability, safety, and efficiency improvements unless the Administrator finds significant harm. - Facility operators: Adds clear exceptions for changes meant to reduce emissions per unit or to restore safety and reliability, so those projects generally would not trigger permits unless they raise maximum hourly emissions enough to harm health or the environment. - Regulators and permitting authorities: Narrows PSD and nonattainment construction definitions to physical work on discrete emissions-unit parts, which focuses preconstruction review on concrete, measurable changes. - Communities near major plants: Fewer alterations may require New Source Review because the bill emphasizes actual hourly emission increases and annual actual emissions when deciding modifications.

## Provisions PRIA read

- Fewer pollution permits for plant owners: benefit, medium. This bill would change when a plant change counts as a "modification" that triggers pollution permits. A change would increase emissions only if the post-change maximum hourly emission rate is higher than any hour in the prior 10 years. Projects meant to cut pollution per unit or to restore, mainta…
- Limits on air permits for large plants: benefit, medium. This bill would narrow when preconstruction air permits are required at major emitting facilities. PSD preconstruction rules would apply only to physical construction of discrete parts of an emissions unit. The bill would define "emissions unit" as any part of a stationary source that emits or can…
