				  entirely submerged when the liquid level is six (6) inches above the bottom of
				  the tank; or when applied to a tank which is loaded from the side, shall mean
				  any fill pipe the discharge of which is entirely submerged when the liquid

				  manifold or vent piping is also considered a substantial
				  modification.

				  system" means a Stage II vapor collection and control system which employs a
				  pump, blower or other vacuum inducing device to collect and/or process gasoline

				  between the vapor spaces of an unloading vessel and a receiving vessel such
				  that vapors displaced from the receiving vessel are transferred to the vessel
				  being unloaded.

				  means equipment that allows no loss of vapors. Equipment is considered
				  vapor-tight if the vapor concentration at a potential leak source is not equal
				  to or greater than 100 percent (100%) of the Lower Explosive Limit when
				  measured with a combustible gas detector, calibrated with propane, at a
				  distance of one (1) inch from the source.
30. "Vapor-mounted seal" means a primary seal
				  mounted so there is a vapor space underneath the seal. The annular vapor space
				  is bounded by the bottom of the primary seal, the tank wall, the liquid
				  surface, and the floating roof.
