Dear Ms. McNelis:

In a letter to the Pipeline and Hazardous Materials Safety Administration (PHMSA), dated January 19, 2024, you requested an interpretation of the Federal pipeline safety regulations in 49 Code of Federal Regulations (CFR) Parts 191 and 192. Specifically, you requested an interpretation with respect to the definition of a master meter system under § 191.3.

You stated that the City of Kansas City (the City) constructed an airport terminal that opened on February 28, 2023. During the construction process, the operator of the local gas distribution company (LDC), Spire Missouri, provided natural gas service to the airport through a single large meter. The City constructed natural gas distribution piping within the airport terminal to serve concessionaries within the new airport terminal.

You stated that the natural gas distribution piping installed by the City consists of both above-ground and buried piping. The buried pipe is a 6-inch diameter high density polyethylene (HDPE) pipeline, "connecting from the outlet of the LDC's meter to the transition to steel prior to entering the new airport terminal." Within the terminal, the piping consists of welded, threaded, and mechanically joined steel pipe, ranging from 6-inch to 1-inch diameter at the various concession areas. The City furnishes utilities, including natural gas, to food and beverage providers (sublessees) renting space within the terminal. Sublessees utilize natural gas for cooking food, which is sold within the airport terminal. Your letter does not specify whether the concessionaries currently purchase metered gas or purchase gas by rents or other means.

Applicable definitions under 49 CFR § 191.3 are reprinted below:

Master Meter System means a pipeline system for distributing as 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;

Operator means a person who engages in the transportation of gas.

You asked PHMSA the following questions in your letter, and PHMSA's response follows each question.

Question 1: Does this system meet the definition of master meter system in 49 CFR § 191.3?

Response to Question 1: Yes, the pipeline system at the Kansas City Airport as described in your letter constitutes a master meter system in which the City of Kansas City is the operator. The pipeline system is used for distributing gas, where the operator (the City) purchases metered gas from an outside source (the LDC) and distributes the gas within a definable area (the airport) for resale through a gas distribution pipeline system. Using the gas distribution pipeline system within the airport, your letter indicates the City supplies gas to the ultimate consumer (the concessionaries). Your letter was not clear whether the concessionaries purchase the gas directly through a meter or by other means, such as by rents.

Question 2: Would the applicability of the definition be different under the following situations?

Question 2a: If the cost of gas is individually metered to the sublessees?

Response to Question 2a: No, the applicability of the definition would not be different (i.e., the system remains a master meter system) if the cost of gas is individually metered to the sublessees. In this scenario, the City's gas distribution pipeline system is supplying the ultimate consumer who purchases the gas directly through a meter.

Question 2b: If the cost of gas is prorated based on some factor (e.g., square footage) as opposed to metering?

Response to Question 2b: No, the applicability of the definition would not be different (i.e., the system remains a master meter system) if the cost of gas is prorated based on some factor (e.g., square footage) as opposed to metering. In this scenario, the City's gas distribution pipeline system is supplying the ultimate consumer who purchases the gas by other means, such as rents.

Question 2c: If the cost of gas was not directly passed on to sublessees through metering or prorating, but indirectly through rent of space?

Response to Question 2c: No, the applicability of the definition would not be different (i.e., the system remains a master meter system) if the cost of gas was not directly passed on to sublessees through metering or prorating, but indirectly through rent of space. In this scenario, the City's gas distribution pipeline system is supplying the ultimate consumer who purchases the gas by other means, such as rents.

Question 2d: If the City outsources management of the sublessees to another company, and that company recovers the cost of gas from the individual sublessees?

Response to Question 2d: No, the applicability of the definition would not be different (i.e., the system remains a master meter system) if the City outsources management of sublessees to another company, and that company recovers, on behalf of the City, the cost of gas from the individual sublessees. In this scenario, PHMSA presumes that the City remains the operator of the gas distribution pipeline system. If the City outsources the operation and management of the pipeline system within the airport to another entity, then that entity could become the operator of the master meter system.
