New Source Performance Standards
['Air Programs']
- NSR is source-specific, whereas the NSPS program applies to all sources nationwide.
The Clean Air Act (CAA) requires the Environmental Protection Agency (EPA) to create a list of the important categories of stationary sources of air pollution, and to establish federal standards of performance for new sources within these categories. These New Source Performance Standards (NSPS) apply to newly constructed sources or those that undergo major upgrades or modifications. The NSPS include both equipment specifications and operation and measurement requirements.
The NSPS are codified in 40 CFR Part 60.
NSPS vs. NSR
The important difference between the New Source Review (NSR) permits and the NSPS program is that NSR is source-specific, whereas the NSPS program applies to all sources nationwide. This gives states the authority to require more stringent controls to meet the ambient air quality standards in specific geographic areas.
