2. MEASUREMENTS AND MEASURING EQUIPMENT

2.1 Unit of Measurement and Basis of Measurement of Gas:

The volumetric measurement base shall be one (1) cubic foot of gas

at an absolute pressure of fourteen and seventy-three-hundredths

(14.73) psia at a temperature of sixty (60) degrees Fahrenheit.

Measurement shall be in accordance with the March, 1978 Revision of

the American National Standard ANSI/API 2530, First Edition,

Orifice Metering of Natural Gas. The data, procedures, reporting

and equipment used to determine the quantity of gas measured shall

be as follows:

(a) Atmospheric Pressure: The assumed atmospheric pressure shall be

twelve and twenty-hundredths (12.20) psia at the Idaho-Nevada

Receipt Point, twelve and fifty-eight-hundredths (12.58) psia

at the Wadsworth Junction Receipt Point, twelve and sixty-five-

hundredths (12.65) psia at the LNG Plant, and as specified in

the executed Service Agreement at the Delivery Point(s).

(b) Flowing Temperature: The temperature of the natural gas flowing

through Paiute's meter stations shall be obtained by the use of

a recording thermometer or using a meter correcting apparatus

correcting to sixty (60) degrees Fahrenheit.

(c) Specific Gravity: The air specific gravity of gas received and

delivered hereunder shall be determined by means of a recording

gravitometer or gas chromatgraphy or other generally accepted

methods of determining specific gravity.

(d) Ownership of Gas Custody Transfer Measuring Equipment: Paiute

shall install, own, maintain and operate at points of delivery

a measuring station properly equipped with the necessary

metering equipment by which the quantity of gas received and
