(28) Low-pressure distribution system means a distribution system in which the gas pressure in the main is substantially the same as the pressure provided to the typical customer.

(29) Main means a distribution line that serves as a common source of supply for more than one service line.

(30) Master meter system means a pipeline system for distributing gas within, but not limited to, a definable area, such as a mobile home park, housing project, or apartment complex, where the operator purchases metered gas from an outside source for resale through a gas distribution pipeline system. The gas distribution pipeline system supplies the ultimate consumer who either purchases the gas directly through a meter or by other means, such as by rents.
