GENERAL TERMS AND CONDITIONS
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
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.
