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.
