GENERAL TERMS AND CONDITIONS

(continued)

4. MEASUREMENT

The volume and total heating value of the gas shall be determined as

follows:

a. The unit of gas transported shall be one million (1,000,000) Btu's

(as defined in Section 1 hereof) (MMBtu). The number of MMBtu's

received or delivered shall be determined by multiplying the

number of cubic feet of gas received or delivered, measured on the

measurement basis herein after specified, by the total heating

value of such gas, in British thermal units per cubic foot, and by

dividing the product by a million (1,000,000).

b. Unit of Volume. The unit of volume for the purpose of measurement

and for the determination of total heating value shall be one

cubic foot of gas at a temperature of sixty (60) degrees

Fahrenheit and an absolute pressure of 14.73 psia.

c. Assumed Atmospheric Pressure. The average atmospheric pressure

shall be assumed to be fourteen and seventy-three hundredths

(14.73) pounds per square inch absolute (14.73 psia) irrespective

of actual elevation or location of the point of delivery above sea

level or variations in such atmospheric pressure from time to

time.

d. Flowing Temperature. At points of delivery where the installation

of a recording thermometer is provided, the arithmetic average of

the temperature of the gas, flowing through the meters, as

recorded, shall be used in computing gas volumes; where recording

thermometers, correcting indices or temperature compensating

meters are not installed, the temperature of the gas shall be

assumed to be the climatological standard normal average monthly

temperature as established by the nearest National Oceanic and

Atmospheric Administration weather bureau and published by the

U. S. Department of Commerce.

e. Orifice Meters. When orifice meters are used the volumes

delivered shall be computed in accordance with the American Gas

Association's Gas Measurement Committee Report No. 3 (API 14.3)

latest edition.
