Current through Register Vol. 51, No. 14, July 12, 2024
A. In this chapter,
				  the following terms have the meanings indicated.
B. Terms Defined.
(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.
(6) "Internal floating roof" means a double
				  deck or a pontoon single deck cover which rests upon and is supported by the
				  liquid being contained in a closed top tank.
(6-1) "Marine vessel" means any tank ship or barge that
					 transports volatile organic compounds (VOCs) in bulk as cargo.
(7) "Motor vehicle" means a
				  vehicle registered with the Maryland Motor Vehicle Administration or the
				  equivalent agency of any other state.
(8) "Pipeline breakout station" means a
				  facility that receives gasoline from a main pipeline and distributes the
				  gasoline by smaller spur pipelines to bulk gasoline terminals.
(9) "Primary seal" means a continuous seal in
				  a storage tank that extends from a floating roof to the tank wall to prevent
				  the escape of vapors into the atmosphere.
(10) "Secondary seal" means a continuous seal
				  in a storage tank that extends from the floating roof to the tank wall covering
				  the entire primary seal.
(11) "Tank
				  truck" means a truck or trailer equipped with storage tanks and used for the
				  transport of gasoline or volatile organic compounds (VOC) from sources of
				  supply to stationary storage tanks.
(12) "Vapor balance system" means coaxial or
				  dual piping that creates a closed system between a tank truck and a stationary
				  storage tank and contains the vapors during the transfer of gasoline.
(13) "Vapor control system" means any piping,
				  hoses, equipment, and devices that collect and process gasoline or VOC vapor,
				  using a vapor processing system.
(14) "Vapor processing system" means any
				  equipment used for recovering or oxidizing VOC vapors.
