Major stationary source
Encyclopedia
A major stationary source is a source that emits more than a certain amount of a pollutant
as defined by the U.S. Environmental Protection Agency
(EPA). The amount of pollutants allowed for certain new sources is defined by the EPA's New Source Performance Standard
s (NSPS).
A stationary source in air quality terminology is any fixed emitter of air pollutants, such as fossil fuel
burning power plants, petroleum refineries, petrochemical plants
, food processing plants
and other heavy industrial sources.
A mobile source in air quality terminology is a non-stationary source of air pollutants, such as automobiles, buses, trucks, ships, trains, aircraft and various other vehicles.
Pollutant
A pollutant is a waste material that pollutes air, water or soil, and is the cause of pollution.Three factors determine the severity of a pollutant: its chemical nature, its concentration and its persistence. Some pollutants are biodegradable and therefore will not persist in the environment in the...

New Source Performance Standard
New Source Performance Standards are pollution control standards issued by the United States Environmental Protection Agency . The term is used in the Clean Air Act Extension of 1970 to refer to air pollution emission standards, and in the Clean Water Act referring to standards for discharges...

Fossil fuel
Fossil fuels are fuels formed by natural processes such as anaerobic decomposition of buried dead organisms. The age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years...

Petrochemical
Petrochemicals are chemical products derived from petroleum. Some chemical compounds made from petroleum are also obtained from other fossil fuels, such as coal or natural gas, or renewable sources such as corn or sugar cane....
