What Does NSR Stand For?
NSR stands for New Source Review
New Source Review (NSR) is a regulatory framework under the Clean Air Act that requires industrial facilities to obtain permits before constructing or modifying operations that may emit significant levels of air pollutants. The NSR process ensures that new and modified sources implement the best available control technologies to minimize environmental impact, thereby protecting air quality and public health.
