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.
The Toxics Release Inventory Reporting (Section 313) of "EPCRA requires the EPA and States to collect data on releases and transfers of listed toxic chemicals."

The 1990 CAA Amendments (Pub. L. 101–549 Title III) codified EPA's list, and required creation of technology-based standards according to "maximum achievable control technology" (MACT). Over the years, EPA has issued dozens of NESHAP regulations, which have developed NESHAPs by pollutant, by industry source category, and by industrial process.
New Source Performance Standards (NSPS) are pollution control standards issued by the United States Environmental Protection Agency (EPA). The term is used in the Clean Air Act Extension of 1970 (CAA) to refer to air pollution emission standards, and in the Clean Water Act (CWA) referring to standards for water pollution discharges of industrial wastewater to surface waters.
In December 2008, the D.C. Court of Appeals vacated the CAMR on the grounds that it illegally exempts utilities from the list of regulated source categories under the MACT standards. [35] On March 16, 2011 EPA proposes Mercury and Air Toxic Standards, the first nationwide limits on coal-fired power plant emissions of mercury.
The air emission regulations in the CR, a component of the National Emissions Standards for Hazardous Air Pollutants (NESHAP) under the Clean Air Act, became effective in 2001. The regulations, also known as "Maximum Achievable Control Technology" (MACT) regulations, apply to mills that use chemical pulping and call for hazardous air pollutants ...
The Clean Air Act requires the EPA to set US National Ambient Air Quality Standards (NAAQS) for the six CAPs. [6] The NAAQS are health based and the EPA sets two types of standards: primary and secondary. The primary standards are designed to protect the health of 'sensitive' populations such as asthmatics, children, and the elderly.
Section 202(a)(1) of the Clean Air Act requires the Administrator of the EPA to establish standards "applicable to the emission of any air pollutant from…new motor vehicles or new motor vehicle engines, which in [her] judgment cause, or contribute to, air pollution which may reasonably be anticipated to endanger public health or welfare" (emphasis added).
