Master Meter Systems: Jurisdictional Evaluation & Compliance
The Pipeline and Hazardous Materials Safety Administration (PHMSA) regulates natural gas pipeline systems under federal law (49 CFR Parts 191 & 192). PHMSA defines a master meter gas operator as, 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;
The Three Elements of a Master Meter System:
• Bulk Gas Purchase: Gas is bought from a local utility through a unified primary master meter.
• Private Distribution: Gas runs downstream through privately owned, underground piping infrastructure across the property.
• Downstream Consumption: Tenants consume the gas and pay through sub-meters or consolidated rental/lease agreements.
Some Possible Jurisdictional Status Scenarios
Property Setup Scenario | Jurisdictional Status | Enforcement & Impact |
Scenario A: Multi-unit commercial storefronts. Local utility provides separate individual meters directly to every business space. | NOT Jurisdictional | The public utility retains complete legal responsibility for infrastructure maintenance. |
Scenario B: Mobile home parks, housing projects, or malls. Single utility master meter feeds a private underground network servicing separate lots/tenants. | 100% JURISDICTIONAL | The property owner is legally deemed a pipeline operator subject to state and federal safety inspections. |
Essential Master Meter Compliance Checklist
If your gas network is jurisdictional, you must actively track, perform, and maintain the following core safety requirements:
Operations & Maintenance (O&M;) Plan: Formalized written protocol outlining operations, sub-surface maintenance, and asset repair mandates.
Emergency Response Plan: Documented local procedures detailing instant remediation steps for gas leaks, pipe failures, fires, or unexpected pressure dropouts.
Routine Sub-Surface Leak Surveys: Periodic tracking utilizing specialized leak-detection technology to uncover leaks.
Cathodic Protection (CP) Monitoring: Ongoing electrical field tracking to proactively protect underground metallic pipelines from corrosion and structural degradation.
Operator Qualification (OQ): All technicians servicing the gas pipes are qualified in accordance with 49 CFR 192.
One-Call System Registration: membership with the state's 811 system to manage third-party excavation notices.
Public Awareness Bulletins: Continuous gas education letters delivered directly to tenants highlighting odor markers and emergency reporting steps.
Regulatory Note: Master meter operators are fully exempt from the complex Distribution Integrity Management Program (DIMP) requirements. However, traditional O&M; protocols and regular state-level auditing still apply.
