** A master metered system is a pipeline system, other than one designated as a local distribution system, for distributing natural 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.
