(a) Measurement Unit


The unit of the natural gas deliverable shall be a Dekatherm

(one Dt) of gas on the measurement basis hereinafter set forth.


(b) Quantity and Heating Value


The quantity and the Heating Value of the natural gas delivered

by Company to or for the account of Customer or delivered by

Customer or Customer's transporter to Company for

liquefaction shall be determined as follows:


(i) The unit of measurement for the purpose of service

under any of Company's rate schedules shall be one (1)

dekatherm (Dth), consisting of one million (1,000,000)

British Thermal Units. The number of dekatherms delivered

shall be determined by multiplying the number of cubic

feet of gas received or delivered, measured on the measurement

basis hereinafter specified, by the total heating value of

such gas, in British Thermal Units per cubic foot, as defined

in Section 1 of the General Terms and Conditions, and by

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


(ii) The unit of quantity for the purpose of measurement shall

be 1 cubic foot of gas at a temperature of 60o Fahrenheit

and at an absolute pressure of 14.73 pounds per square inch.


(iii) The unit of weight for the purpose of measurement shall

be one (1) pound mass of gas.


(iv) The average absolute atmospheric pressure shall be assumed

to be 14.7 pounds per square inch.


(v) The temperature of the gas passing through the meters

shall be determined by the use of electronic transducers,

recording thermometer or other temperature measuring devices.

The arithmetic average of the temperature recorded each 24-hour

day shall be used in computing gas quantities or continuous

instantaneous temperature measurements as may be applied to

metering instruments to provide the quantity computation.
