A Master Meter SystemIs Still a Gas Operator.
Mobile home parks, apartment complexes, campuses and housing authorities that buy gas through a master meter and pipe it to tenants are operators under 49 CFR Part 192. X3 keeps the short list of duties that apply in one place, with a reminder before each one is due.

The Duties That Apply to You.
Fewer than a utility carries, but each has a date and an inspector who will ask to see the record.
What makes you an operator
A master meter system buys metered gas from an outside source and distributes it within an area such as a mobile home park, housing project or apartment complex, to people who pay for it directly or in their rent (191.3).
No DIMP plan
Master meter systems are outside the distribution integrity management rules (192.1003(b)(3)), so there is no DIMP plan to keep.
Surveys, corrosion and the emergency plan
Leak surveys (192.723), corrosion monitoring on metallic pipe (192.465, 192.481), an emergency plan (192.615) and qualified people for covered tasks (Subpart N).
Messages to your customers
A written procedure to give your customers public awareness messages twice a year (192.616(j)). No distribution annual report is filed (191.11(b)).

These are federal PHMSA cases. State pipeline safety programs inspect most intrastate and distribution systems, and their findings are not in this data. In Michigan, no new master meter system may be supplied since January 1, 2019 without a commission waiver (Mich. Admin. Code R 460.20335).
