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 list can be found on Wikipedia at National Emissions Standards for Hazardous Air Pollutants, and on EPA at . Subcategories This category has the following 4 subcategories, out of 4 total.
Under the CAA, hazardous air pollutants (HAPs, or air toxics) are air pollutants other than those for which NAAQS exist, which threaten human health and welfare. The NESHAPs are the standards used for controlling, reducing, and eliminating HAPs emissions from stationary sources such as industrial facilities.
Household air pollution (HAP) is a significant form of indoor air pollution mostly relating to cooking and heating methods used in developing countries. [1] Since much of the cooking is carried out with biomass fuel , in the form of wood , charcoal , dung , and crop residue , in indoor environments that lack proper ventilation, millions of ...
sulfur dioxide emissions fell from 31 million tons to 15 million tons; particulate emissions fell by 80%; and; lead emissions fell by more than 98%. A 2020 paper reported that about half of air pollution and half of the resulting deaths are caused by emissions from outside a given state's boundaries, typically from prevailing winds moving west ...
The fugitive air pollutant emission factors from relief valves, piping valves, open-ended piping lines or drains, piping flanges, sample connections, and seals on pump and compressor shafts are discussed and included in the report EPA-458/R-95-017, "Protocol for Equipment Leak Emission Estimates" which is included in the Chapter 5 section of AP ...
HAPs, also known as toxic air contaminants, are defined by the EPA as “those known to cause cancer and other serious health impacts”. [13] In the United States, legislation known as the Clean Air Act mandated the EPA to regulate appropriate levels of HAP emissions from source categories such as industrial and mobile. [14]
A high altitude platform can provide observation or communication services. A high-altitude platform station (HAPS, which can also mean high-altitude pseudo-satellite or high-altitude platform systems), also known as atmospheric satellite, is a long endurance, high altitude aircraft able to offer observation or communication services similarly to artificial satellites.
