The Clean Air Act NSPS dictate the level of pollution that a new stationary source may produce. These standards are authorized by Section 111 of the CAA [2] and the regulations are published in 40 CFR Part 60. [3] NSPS have been established for a number of individual industrial or source categories. Examples:
The National Emission Standards for Hazardous Air Pollutants (NESHAP) are air pollution standards issued by the United States Environmental Protection Agency (EPA). The standards, authorized by the Clean Air Act, are for pollutants not covered by the National Ambient Air Quality Standards (NAAQS) that may cause an increase in fatalities or in serious, irreversible, or incapacitating illness.
Title 40 is a part of the United States Code of Federal Regulations. Title 40 arranges mainly environmental regulations that were promulgated by the US Environmental Protection Agency (EPA), based on the provisions of United States laws (statutes of the U.S. Federal Code).

Major rewrite of CAA, setting National Ambient Air Quality Standards (NAAQS), New Source Performance Standards (NSPS) Hazardous Air Pollutant standards, and auto emissions tailpipe standards.
Tightening U.S. standards "wouldn't improve public health, but it would put as many as 30% of all U.S. counties out of compliance under federal law, leading to aggressive new permitting ...
EPA issues these limitations based on the performance of pollution control and prevention technologies. [22] For existing dischargers, this level of treatment is equivalent to "Best Available Technology Economically Achievable" (BAT) and for new discharges, the treatment level is "New Source Performance Standards" (NSPS).
