What are New Source Performance Standards?
The general provisions to the New Source Performance Standards (NSPS) in 40 CFR Parts 60 and the National Emission Standards for Hazardous Air Pollutants (NESHAP) in 40 CFR Parts 61 and 63, under the Clean Air Act, provide that a source owner or operator may request a determination of whether certain intended actions constitute the commencement of construction, reconstruction, or modification. EPA’s written responses to these inquiries are broadly termed applicability determinations. The NSPS and NESHAP also allow sources to seek permission to use monitoring or recordkeeping which is different from the promulgated requirements. EPA’s written responses to these inquiries are broadly termed alternative monitoring decisions. Further, EPA responds to written inquiries about the broad range of NSPS and NESHAP regulatory requirements as they pertain to a specific source. These inquiries question whether a regulation applies to a specific source, or may relate to the testing, monitoring, reco
New Source Performance Standards (NSPS) are federal standards adopted by the U.S. Environmental Protection Agency (EPA) to regulate air emissions of criteria pollutants by many types of industrial facilities. The standards are intended to promote use of the best air pollution control technologies. All industries subject to NSPS must meet certain general requirements, such as monitoring and recordkeeping. In addition, certain specific requirements apply to each type of industry subject to NSPS. Each NSPS defines the facilities subject to it and prescribes emission limits for specified pollutants, compliance requirements, monitoring requirements, and test methods and procedures.
