The amount of petroleum product that moves through a particular facility during a given period of time.
For example, if a station has a monthly gasoline throughput of 150,000 gallons, it simply means that in a typical month the station dispenses around 150,000 gallons of gasoline.
The term often appears in regulations related to petroleum marketing facilities. A regulation requiring installation of Stage II vapor recovery equipment, may apply only to facilities with a monthly throughput in excess of 10,000 gallons, or a similar figure.
