New Source Performance Standards

Section 111 of the Clean Air Act, "Standards of Performance of New Stationary Sources," requires EPA to establish federal emission standards for source categories which cause or contribute significantly to air pollution. These standards are intended to promote use of the best air pollution control technologies, taking into account the cost of such technology and any other non-air quality, health, and environmental impact and energy requirements. These standards apply to sources which have been constructed or modified since the proposal of the standard. Since December 23, 1971, the Administrator has promulgated 94 such standards and associated test methods. These standards can be found in the Code of Federal Regulations at Title 40 (Protection of Environment), Part 60 (Standards of Performance for New Stationary Sources). For an electronic compilation of the standards, see the Government Printing Office's e-CFR Database. Exit EPA Click for Disclaimer

Generally, state and local air pollution control agencies are responsible for implementation, compliance assistance, and enforcement of the new source performance standards (NSPS). EPA retains concurrent enforcement authority and is also available to provide technical assistance when a state or local agency seeks help. EPA also retains a few of the NSPS responsibilities -- such as the ability to approve alternative monitoring methods -- to maintain a minimum level of national consistency.

If you have questions about the standards, we encourage you to first discuss them with your respective state or local air pollution control agency. If you are located outside the Region 7 geographic area (e.g Iowa, Kansas, Missouri, and Nebraska) please consult with the state or local agency or EPA Regional Office in your area. If you are a state or local agency located in Region 7 and need assistance with the interpretation of regulatory language, please contact us.
