Industry:Pollution control
Uniform national EPA air emission standards that limit the amount of pollution allowed from new sources or from modified existing sources. For more information, please go to our Title V website.
Industry:Pollution control
Those sources for which a methodology is used to estimate emissions. This can include area-wide, mobile and natural sources, and also groups of stationary sources (such as dry cleaners and gas stations). The California Clean Air Act requires air districts to include area sources in the development and implementation of the AQMP. In the California emission inventory all sources which are not reported as individual point sources are included as area sources. The federal air toxics program defines a source that emits less than 10 tons per year of a single hazardous air pollutant (HAP) or 25 tons per year of all HAPs as an area source. For more information, please visit our area-wide source methodologies website.
Industry:Pollution control
Under the Clean Air Act, the rate of emissions that reflects (1) the most stringent emission limitation in the State Implementation Plan of any state for a given source unless the owner or operator demonstrates such limitations are not achievable; or (2) the most stringent emissions limitation achieved in practice, whichever is more stringent.
Industry:Pollution control
The temperature at which a solid becomes a liquid. At this temperature, the solid and the liquid have the same vapor pressure.
Industry:Pollution control
The use of materials, processes, or practices to reduce, minimize, or eliminate the creation of pollutants or wastes. It includes practices that reduce the use of toxic or hazardous materials, energy, water, and/or other resources. For more information, please go to our pollution prevention program website.
Industry:Pollution control
The vapor density is expressed in grams per liter (g / L) and is comparedto the density of air (air=1).
Industry:Pollution control
The warming effect of the Earth's atmosphere. Light energy from the sun which passes through the Earth's atmosphere is absorbed by the Earth's surface and re-radiated into the atmosphere as heat energy. The heat energy is then trapped by the atmosphere, creating a situation similar to that which occurs in a car with its windows rolled up. A number of scientists believe that the emission of CO<sub>2</sub> and other gases into the atmosphere may increase the greenhouse effect and contribute to global warming.

Industry:Pollution control
The weight of a pollutant emitted per unit of time (e.g., tons / year).
Industry:Pollution control
The sum of all hydrocarbon air pollutants except methane. NMHCs are significant precursors to ozone formation.
