(b) "Customer" means any person, firm, associati ## Document text (a) "Utility" means any gas company operating under the jurisdiction of the Commission, including in the case of safety rules and regulations, any interstate pipeline company subject to the safety jurisdiction of the Commission pursuant to G.S. 62 50. (b) "Customer" means any person, firm, association, or corporation, or any agency of the federal, State, or local government, being supplied with gas service by a gas utility. (c) "Premises" means a piece of land or real estate, including buildings and other appurtenances thereon. (d) "Gas plant" means all facilities owned by a gas utility for the production, storage, transmission, and distribution of gas. (e) "Main" means a gas pipe, owned, operated, or maintained by a utility, which is used for the purpose of transmission or distribution of gas, but does not include "gas service line." (f) "Gas service line" is the pipe that runs between a main or a pipeline and a customer's meter. (g) "Meter," without other qualification, shall mean any device, or instrument which is used by a utility in measuring a quantity of gas. (h) "Check flow" means a flow at approximately 20% of the rated capacity of a meter at a pressure of 1-1/2" water column on prover. (i) "Full rated flow" means a flow of 100% of the rated capacity of meter at a pressure of 1-1/2" water column on prover. (j) "Open rated flow" means a flow with meter outlet unrestricted at a pressure of 1-1/2" water column on prover. (k) "Cubic foot" of gas as used in these rules shall have the following meanings: (1) Where gas is supplied and metered to customers at the pressure normally used for domestic customers' appliances, a cubic foot of gas shall be that quantity of gas which, at the temperature and pressure existing in the meter, occupies one cubic foot. (2) When gas is supplied to customers at other than the pressure in (1) above, a cubic foot of gas shall be that quantity of gas which, at a temperature of 60° F. and a base pressure of 14.73 pounds per square inch absolute, occupies one cubic foot, atmospheric pressure assumed to be 14.73. (3) The standard cubic foot of gas for testing the gas itself for heating value shall be that quantity of gas, saturated with water vapor, which at a temperature of 60° F. and a pressure of 30 inches of mercury, occupies one cubic foot. (Temperature of mercury = 32° F. acceleration due to gravity = 32.17 feet per second; density 13.595 grams per cubic centimeter). (l) "Interruption of service" means any disturbance of the gas supply whereby the pilot flame on the appliances of at least 50 customers shall have been extinguished. (m) The abbreviations used, and their meanings, shall be as follows: (1) BTU - British Thermal Unit. (2) LP Gas - Liquified Petroleum Gas. (3) psig - Pounds Per Square Inch, Gauge. (4) W.C. - Water Column.

Chapter 6 also reaches interstate natural-gas companies only insofar as the Commission has safety jurisdiction; it does not establish state jurisdiction over every pipeline or customer-owned installation in North Carolina.", "incorporationCaveat": "R6-39 and R6-41 incorporate federal pipeline requirements and amendments, including 49 CFR Parts 191, 192, 193, 198, and 199, with stated North Carolina modifications.
