"Corporate or commercial fleets" means vehicles used for business purposes which are owned by corporations, governments, universities or other organizations.8. "Daily throughput" means the average amount of gasoline that a bulk gasoline terminal or plant dispenses in a day from that facility and is defined as the thirty (30) day rolling average throughput of the facility. This is used to determine applicability, not compliance.9. "External floating roof" means a storage vessel cover in an open top tank consisting of a double deck or pontoon single deck which rests upon and is supported by the petroleum liquid being contained and is equipped with a closure seal or seals to close the space between the roof edge and tank shell.10. "Gasoline" means any petroleum distillate having a Reid vapor pressure of more than four (4.0) psia as determined by ASTM Method D323-15a, incorporated in § 11.2(C)of this Part. This term includes but is not limited to mixtures of alcohols and gasoline.11. "Gasoline dispensing facility" means any site where gasoline is dispensed to motor vehicle gasoline tanks from stationary storage vessels.12. "Leak" means a meter reading from a combustible gas detector greater or equal to one hundred percent (100%) lower explosive limit as propane.13. "Liquid-mounted seal" means a primary seal mounted in continuous contact with the liquid around the circumference of the tank between the tank wall and the floating roof.14. "Monthly throughput" means the amount of gasoline that a gasoline dispensing facility dispenses in a month. This amount is used to determine applicability, not compliance.15. "Motor Vehicle Fuel"? means any petroleum distillate having a Reid Vapor Pressure or more than four pounds per square inch as determined by ASTM Method D323 and which is used primarily to power motor vehicles. This definition includes, but is not limited to, gasoline and mixtures of simple alcohols and gasoline. This definition excludes jet fuel.16. "Onboard refueling vapor recovery" or "ORVR" means a vehicle emission control system that captures fuel vapors from the vehicle gas tank during refueling.17. "Operator" means any person who leases, operates, controls or supervises a facility at which gasoline is dispensed.18. "Owner" means any person who has legal or equitable title to the gasoline storage vessel at a facility.19. "Petroleum liquids" means crude oil, condensate and any finished or intermediate products manufactured or extracted in a petroleum refinery whose true vapor pressure is greater than 1.52 psia (10.5 kilo pascals) at sixty-nine degrees Fahrenheit (69ºF).20. "Splash filling" means the filling of a tank truck or stationary storage tank through a pipe or hose whose discharge opening is above the surface level of the liquid in the tank being filled.21. "Stage I or Phase I vapor control system" means a closed system between the vapor spaces of an unloading gasoline tank truck and a receiving gasoline dispensing facility storage tank such that vapors displaced from the storage tank are transferred to the tank truck that is being unloaded.22. "Stage II vapor collection and control system" means a system which collects gasoline vapors displaced from motor vehicle gasoline tanks during refueling and which routes the vapors to a stationary storage tank.23. "Submerged fill pipe" means any fill pipe the discharge opening of which is 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 level is eighteen (18) inches or twice the diameter of the fill pipe, whichever is greater, above the bottom of the tank.24. "Submerged filling" means the filling of a tank truck or stationary tank through a submerged fill pipe whose discharge opening is entirely submerged when the pipe normally used to withdraw liquid from the tank can no longer withdraw any liquid.25. "Substantially modified" means a modification of an existing gasoline dispensing facility which involves the addition, repair, replacement, or reconditioning of stationary storage tanks. Any excavation at an existing gasoline dispensing facility which has the potential to affect the integrity or pitch of any Stage II vapor return, manifold or vent piping is also considered a substantial modification.26. "Vacuum assist 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 vapors.27. "Vapor" means those components of gasoline that have been volatilized to the gaseous phase from the liquid phase.28. "Vapor balance system" means a combination of pipes or hoses which create a closed system 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.29. "Vapor tight" 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.250 R.I. Code R. 250-RICR-120-05-11.3
