New Source Review - Subchapter B Permit
If a facility is not de minimis and cannot meet a PBR or standard permit, it must be authorized by a case-by-case NSR permit. These types of authorizations provide more flexibility to applicants because they can authorize more emissions and, unlike a PBR or standard permit, facility-specific information can be considered during the technical review, which includes a BACT and impacts review.
NSR permits are subject to public notice and an opportunity for a contested case hearing. These permits are issued with a ten-year renewal cycle. However, some older NSR permits were previously issued with a 15-year renewal date.
More specifics on the NSR process for new permits, amendments, and renewals will be discussed in Module 3.
