New Source Review Permitting Programs
New Source Review (NSR) is a title applied to programs regulating the new construction of, and/or modifications to, industrial sources which emit, or will emit, air pollutants. The permits resulting from this process are termed NSR, Prevention of Significant Deterioration, Minor New Source Review, and/or Nonattainment Area Permits depending on the issuing agency, area designation for state and National Ambient Air Quality Standards (attainment, nonattainment, and unclassifiable areas), and the amount and type of pollutants that the source will emit. In California, local air districts have the primary responsibility for issuance of air permits.
