(1) "Bulk gasoline plant" means a gasoline storage and distribution facility with a maximum daily throughput of 20,000 gallons (75,500 liters) or less which receives gasoline from bulk terminals, stores it in tanks, then dispenses the gasoline via trucks to local farms, businesses, and gasoline dispensing facilities.

(2) "Bulk gasoline terminal" means a gasoline storage facility with a minimum daily throughput greater than 20,000 gallons (75,500 liters) which receives gasoline by pipeline, ship, or barge and delivers gasoline to bulk gasoline plants or to commercial or retail accounts by tank truck.

(3) "External floating roof" means a double deck or a pontoon single deck cover in an open top tank which rests upon, and is supported by, the liquid being contained.

(4) "Gasoline" means a petroleum distillate or alcohol, or their mixtures, having a true vapor pressure within the range of 1.5 to 11 pounds per square inch absolute (psia) (10.3 to 75.6 kilonewtons/square meter) that is used as fuel for internal combustion engines or aircraft.

(5) "Gasoline leak" means a reading equal to or greater than 100 percent of the lower explosive limit measured as propane at a distance of 1 inch from any point on the perimeter of a potential leak source.
