GENERAL TERMS AND CONDITIONS

(Continued)

 

3. MEASUREMENT

 

3.1 Measurement Unit: The unit of measurement of gas delivered

by Transporter shall be a dekatherm.

 

3.2 Determination of volume and total heating value: The volume

and the total heating value of the gas delivered by Transporter

shall be determined as follows:

 

(a) The unit of volume, for the purposes of measurement,

shall be one cubic foot of gas at a temperature of 60 degrees

Fahrenheit, and at a pressure of thirty-three hundredths (.33)

pounds per square inch above an assumed atmospheric pressure of

fourteen and four-tenths (14.4) pounds per square inch (fourteen

and seventy-three hundredths (14.73) pounds per square inch

absolute pressure.)

 

The reporting basis for gas volume is as cubic feet at

standard conditions of 14.73 psia, 60 degrees F, and dry. For gas

volumes reported in cubic meters, the standard conditions are

101.325 kPa, 15 degrees C, and dry. The reporting basis for

gigacalorie is as 1.035646 Kg/cm2 and 15.6 degrees C and dry.

 

(b) The total heating value of the gas per cubic foot shall

be that reported to the Transporter by the interconnecting

upstream pipeline(s) or Canadian Supplier(s).

 

(c) The Dth delivered shall be calculated by multiplying

the Mcf delivered by a fraction, the numerator of which is the

total heating value and the denominator of which is 1,000.

 

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

shall be determined for any day by the continuous use of a

recording thermometer so installed that it may properly record the

temperature of the gas flowing through the meters. The

arithmetical average of the temperature recorded each day shall be

used in computing gas volumes.

 

(e) The specific gravity of the gas delivered by

Transporter on any day shall be that reported to Transporter by

the upstream pipeline or Canadian supplier.
