Curtailment.

"Curtailment" means reduction or cutoff of supply to interruptible contract customers that is related directly to deficiencies in gas supply.

Subp. 6.

Design day.

"Design day" means the 24-hour period of the greatest theoretical gas demand at a given average temperature.

Subp. 7.

Design day availability.

"Design day availability" means the volume of each type of gas arranged to be available on the design day and the maximum total volume of such supply.

Subp. 8.

Equivalent Mcf.

"Equivalent Mcf" shall mean the volume in thousands of cubic feet (Mcf) of the liquefied gas if it were gasified, measured at 14.73 pounds per square inch absolute (psia) and 60 degrees Fahrenheit.

Subp. 9.

Firm contract customers.

"Firm contract customers" means customers served under schedules or contracts that neither anticipate nor permit interruption unless a state of emergency exists.

Subp. 10.

Forecast years.

"Forecast years" means the 18 calendar years consisting of the calendar year the application is filed with the agency, the ten previous calendar years, and the first five, tenth, and 15th subsequent calendar years.

Subp. 11.

Gas volume.

"Gas volume" means the volume of gas as measured at 14.73 psia and 60 degrees Fahrenheit. All volumes shall be in Mcf unless otherwise stated.

Subp. 12.

Interruptible contract customers.

"Interruptible contract customers" means customers served under schedules or contracts that anticipate or permit interruption of service during the term of the contract.

Subp. 13.

Large gas pipeline.

"Large gas pipeline" means any pipeline for transporting natural or synthetic gas at pressures in excess of 200 psia with more than 50 miles of its length in Minnesota.

Subp. 14.

Large liquefied gas storage facility.

"Large liquefied gas storage facility" means any facility designed for or capable of storing on a single site more than 100,000 gallons of liquefied natural or synthetic gas.

Subp. 18.

MMcfpd-mile.

"MMcfpd-mile" means a descriptive unit used as a measure of the size of the pipeline, the quantity of which is obtained by multiplying:

A.

either the length in miles of the Minnesota portion of the new (sections of) pipeline, or 50 if the capacity expansion would be achieved by adding power, with

B.

the new or additional design throughput in thousands of Mcf or equivalent Mcf-per-day (MMcfpd).

If the capacity would be expanded by a combination of looping and adding power, then the MMcfpd-mile corresponding to each method of expansion shall be calculated and the pipeline size shall be the sum of the two quantities thus calculated.

Subp. 19.

Natural gas.

"Natural gas" means a naturally occurring mixture of hydrocarbon and nonhydrocarbon gases and vapors found in porous geologic formations beneath the earth's surface, the principal constituent of which is methane.

Subp. 20.
