Definition - What does Stationary Source mean?
A stationary source refers to qualitative term used to describe any fixed emitter of air pollutants, such as crude oil-burning power plants, oil refineries, petrochemical plants and other heavy industrial facilities. The air pollutants released from a stationary source may accelerate the corrosion process.
Stationary sources are also known as point sources.
Corrosionpedia explains Stationary Source
Examples of stationary sources are buildings, facilities or structures that produces air pollutants. However, it does not include air pollutants released from a vehicle's internal combustion engine whether or not the vehicle is designated for transportation purposes.
Stationary sources play a critical role in the overall level of pollution reported from nearby industrial operations, and as such must be adequately represented in pollution calculations.
Facility pollution contributors that are mobile in nature, such as vehicles, temporary fixtures and spray units, are referred to as non-point sources.
