criteria air pollutants - primary ( meaning emmitted directly) and secondary (meaning formed by chemical reactions amoung primary pollutants in the atmosphere) pollutants that pose health-based risks. These include: PM-10 (particulate matter with a diameter less than 10 micrometers), SO2, NO2, CO, particulate Pb,and ozone.
emmission factor - a measure of an average rate of emmission of a pollutant for a defined activity rate.
emmission standards - used to regulate emmissions from industrial sources and to estimate the maximium rate of emmissions from a propsed new source.
fuel NOx - results from the combustion of fuels that contain organic nitrogen; this depends on local combustion conditions and nitrogen content of the fuel.
fugitive emmissions - emmissions that are not captured by the system process.
global climate change (GCC) - also termed the "green house effect", refers to the retension of infrared radiation (heat) by certain gases in the atmosphere before the heat is lost to space resulting in enhanced warming of the earth's average global temperature.
NAAQS - National Ambient Air Quality Standards
NESHAPs - National Emmssion Standards for Hazardous Air Pollutants
non-point source - an emmission from a mobile source.
NSPS - National New Source Performance Standards
point source - emmission from a stationary source.
thermal NOX - formed by reactions between nitrogen and oxygen in the air used for combustion; highly depandant upon temperature.
thermal oxidizer - also termed an afterburner, method of pollution control that can applied to incineration as a method of pollution control for air polluted with small particles or combustable solids or liquids.
